Background: Chest wall perforator flaps are emerging in oncoplastic breast conservation, mostly as an alternative to mastectomy. However, standardization and consensus on patient selection, techniques, and outcomes have not yet been reached. The aim of this international multicentre collaborative study was to explore practice patterns and outcomes in high-volume centres from different countries., Methods: Patients with both pre-invasive and invasive breast cancer treated at the Uppsala University Hospital in Uppsala, Sweden, the Royal Marsden Hospital in London, UK, and the Westmead Breast Cancer Institute in Sydney, Australia, were included in this study. The rationale for offering chest wall perforator flaps and surgical outcomes were prospectively documented., Results: In total, 603 patients were analysed median age of 54 (interquartile range (i.q.r.) 48-63) years, median BMI of 25.0 (i.q.r. 22.5-28.1) kg/m2, median tumour extent of 30 (IQR 19-45) mm, median breast volume of 280 (i.q.r. 216-430) ml, and median calculated resection ratio of 16% (i.q.r. 9%-28%). In 67.7%, the treating surgeon had offered chest wall perforator flaps to avoid mastectomy. The procedure was performed as day surgery in 69.5% of patients, with an overall complication rate of 8.6% and the majority of complications being classified as Clavien-Dindo grade I (5.3% of patients). The re-excision rate was 15.9%, with only 1.5% of patients converting to a mastectomy. There were no flap losses. At a median follow-up of 22 (range 12 to 98) months, rates of local recurrence, distant recurrence, and breast cancer-related mortality were 1.9%, 4.9%, and 1.7% respectively., Conclusion: Chest wall perforator flaps are a useful option to allow more women to avoid mastectomy. In experienced hands, the procedure is safe and should be offered to suitable patients., (© The Author(s) 2024. Published by Oxford University Press on behalf of BJS Foundation Ltd.)

Rationale: Persistent left superior vena cava (PLSVC) is a rare congenital venous anomaly occurring in approximately 0.3% to 0.5% of the population. The presence of PLSVC complicates central venous catheter placement, increasing procedural risks. This case report describes the successful placement of a chest wall venous infusion port in a patient with PLSVC, offering valuable insights for managing similar cases and ensuring safer clinical outcomes., Patient Concerns: A 51-year-old female, 3 weeks post-right breast cancer surgery, was admitted for her first adjuvant hemotherapy session. She requested the placement of a venous infusion port due to the prolonged duration of chemotherapy., Diagnoses: Imaging studies suggested the presence of PLSVC. Echocardiography revealed a dilated coronary sinus, and subsequent chest computed tomography and angiography confirmed the presence of PLSVC., Interventions: A chest wall venous infusion port was inserted via the left internal jugular vein. Due to the PLSVC, the catheter was adjusted to ensure proper placement., Outcomes: The patient successfully completed chemotherapy without any complications or discomfort associated with the venous port. Imaging studies, including chest X-ray and computed tomography, confirmed proper port function and catheter positioning, with no evidence of thrombosis, infection, or other related issues. The patient remained in good overall condition throughout the treatment., Lessons: Detailed preoperative evaluations, intraoperative imaging guidance, and postoperative follow-ups are crucial for the safe and effective management of PLSVC patients undergoing central venous catheter placement., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Resection of thoracic wall tumors results in significant defects in the chest wall, leading to various complications. In recent years, the use of three-dimensional (3D) printed titanium alloy prostheses in clinical practice has demonstrated enhanced outcomes in chest wall reconstruction surgery. A cohort of seven patients with sternal tumors was identified for this study. Following a helical CT scan, a digital model was generated for the design of the prosthesis. Subsequently, the tumors were then removed together with the affected sternum and ribs. The chest wall was then reconstructed using 3D-printed titanium alloy prosthesis for bone reconstruction, mesh for pleural reconstruction, and flap for soft tissue reconstruction. Patients were monitored for a period of one year post-surgery. In the seven cases examined, the tumors were found in various locations with varying degrees of invasion. Based on the scope of surgical resection and the size of the defect, 3D-printed titanium alloy prosthesis was custom-designed for chest wall reconstruction. Prior to bone reconstruction, pleural reconstruction was achieved with Bard Composix E/X Mesh, while soft tissue repair involved muscle flap and musculocutaneous flap procedures. A one-year follow-up assessment revealed that the utilization of the 3D-printed titanium alloy prosthesis led to secure fixation, favorable histocompatibility, and enhanced lung function. The findings demonstrate that the utilization of 3D printed titanium alloy prostheses represents a significant advancement in the field of chest wall reconstruction and thoracic surgical procedures., (© 2024.

Background: The cross-bar technique of minimally invasive pectus excavatum (PE) correction remains underreported, which is especially true of pediatric patients. We therefore reviewed the experience of a Turkish and an Austrian center. An additional novelty characterizing both pediatric cohorts was the use of short bars., Methods: In a retrospective study, pediatric PE corrections involving 'short bars crossed' were analyzed for complications and intra-/postoperative outcomes. Cases with two or three bars were included, given that a horizontal third bar was placed whenever considered useful for upper-chest elevation. All bars were fitted with a single stabilizer near the surgical entry point. In the Austrian center, intercostal nerve cryoablation was used for pain management. Descriptive statistics are presented., Results: Seventy-eight patients ≤18 years old were evaluable at the Turkish (n = 56) and Austrian (n = 22) centers. Total median values were 16.2 (IQR: 15.1-17.4) years for age and 4.60 (IQR: 3.50-6.11) for Haller index. Ten mild or moderate complications (12.8%) were observed, including just one revision requirement due to bar migration (1.28%). Intercostal nerve cryoablation (n = 13) was associated with longer surgical procedures at 150 (IQR: 137-171) versus 80 (IQR: 60-100) minutes but with shorter hospital stays, given an IQR of 3-4 days versus 4-5 days., Conclusion: 'Short bars crossed'-with a single stabilizer in a ventral position close to the surgical entry point-ensure a wide distribution of forces, protect against bar migration, are safe and effective, and offer stability at an age characterized by growth and physical activity., Level of Evidence: IV., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to disclose., (Copyright © 2024 The Author(s).

Introduction: Chest wall reconstruction in children after large resection of tumors may be performed with rigid or soft materials. Cementoplasty is commonly used with the "Sandwich" method i.e. gore-tex meshes surrounding both faces of the cement., Hypothesis: Is antibiotic loaded single-side gore-tex "Tartine" methyl-methacrylate cementoplasty an interesting alternative to the double-side "sandwich" method for chest wall reconstruction?, Material and Methods: Consecutive patients who were treated from 2011 to 2023 in our hospital were included., Results: Among the ten children treated with a median 5.6 years follow-up, there were no surgical complications related to the reconstruction, loss of function, infections, post operative complications (versus 22.7% in meta-analysis encompassing the 50 rigid reconstructions reported worldwide) nor scoliosis (versus 25%). Three patients have an asymmetric chest wall appearance., Discussion: "Tartine" cementoplasty is a simple, low-cost technique for pediatric chest wall reconstruction. It is well tolerated and checks key demands for chest wall reconstructions., Level of Evidence: IV; retrospective case series., (Copyright © 2024. Published by Elsevier Masson SAS.)

Present case is a 74-year-old man, given a diagnosis of huge mediastinal dedifferentiated liposarcoma. Surgical complete resection of the tumor and involved anterior chest wall( all body of sternum and bilateral 3rd~5th rib) followed by reconstruction of the defected chest wall using three artificial prosthetic materials of putting titanium mesh plate between ePTFE mesh seat at inner (mediastinal) site and polypropylene mesh seat at outer site was perfomed. The patient is doing well without respirately failure and disease free even 6 years after surgery. This surgical procedure could be thought of effective treatment method in sense of preventing postoperative complication and preserving respiratory function.

Background: Intercostal nerve cryoablation (INC) has been shown to reduce postoperative pain and length of stay following surgical correction of pectus excavatum (SCOPE). Some patients have developed chest wall dermatological symptoms after INC that can be mistaken for metal allergy or infection. The purpose of this study is to report the symptoms, severity, incidence, and treatment of post-cryoablation dermatitis., Methods: A retrospective single institution review was performed for patients who underwent SCOPE with and without INC between June 2016 and March 2023 to assess for incidence of postoperative dermatological findings. Characteristics associated with these findings were evaluated., Results: During study period, 383 patients underwent SCOPE, 165 (43.1%) without INC and 218 (56.9%) with. Twenty-three (10.6%) patients who received INC developed exanthems characteristic of post-cryoablation dermatitis with two distinct phenotypes identified. No patients who underwent SCOPE without INC developed similar manifestations. Early dermatitis, characterized by a painless, erythematous, and blanching rash across the anterior thorax, was observed in 16 patients, presenting on median postoperative day 6.0 [IQR 6.0-8.5], with median time to resolution of 23.0 [IQR 12-71.0] days after symptom onset. Late dermatitis, characterized by hyperpigmentation spanning the anterior thorax, was observed in 7 patients, presenting on median postoperative day 129.0 [IQR 84.5-240.0], with median time to resolution of 114.0 [IQR 48.0-314.3] days., Conclusion: This is the first report of dermatological manifestations following SCOPE with INC, a phenomenon of unknown etiology and no known long-term sequela. In our experience, it is self-resolving and lacks systemic symptoms suggesting observation alone is sufficient for resolution., Level of Evidence: IV., (Copyright © 2024 Elsevier Inc.

Background: Scoliosis is one of the long-term consequences of surgical resection of pediatric chest wall tumors. This study aimed to identify the risk factors associated with scoliosis development following the resection of chest wall tumors., Methods: Retrospective cohort study of 64 children who underwent resection of malignant chest wall tumors from 2009 to 2022. Univariate and multivariate analyses were used to investigate factors associated with scoliosis development., Results: The median age at the time of surgery was 7 years (range, 3-21), with 33 (51.6%) patients undergoing surgery before the age of 10 years. The most common histology was Ewing sarcoma (n = 57). A median of 3 (range, 1-5) contiguous ribs were resected. A total of 34 (53.1%) patients had anterior CWTs and 30 (46.9%) had posterior CWTs. Concomitant partial lung and diaphragmatic resection were performed in 12 patients (lung, n = 7; diaphragm, n = 5). Scoliosis convex towards the resection side developed in 21 (32.8%). The primary risk factors for scoliosis were resecting 3 or more ribs (OR 6.44) and resection of the posterior rib segment (OR 5.49). Patients with a tumor resection below 10 years old were not associated with a higher risk of scoliosis., Conclusions: Scoliosis following resection of a primary malignant pediatric chest wall tumor is associated with resection involving three or more ribs and resection of the posterior rib sector., Type of Study: Retrospective observational., Level of Evidence: IV., Competing Interests: Conflict of interest The authors declare there are no competing interests related to this work., (Copyright © 2024 Elsevier Inc.

Introduction: A reconstructive option for extensive chest wall reconstruction is the free myocutaneous vastus lateralis muscle (VL) flap which can be performed in isolation or in conjunction with a fasciocutaneus anterolateral thigh (cVLALT) and/or myofasciocutaneous tensor fascia lata flap (cVLTFL). We aimed to directly compare the outcomes of these reconstructive options., Methods: Patients who underwent oncological chest wall reconstruction with a free VL, cVLALT, or cVLTFL flap between February 2010 and 2022 were included in this retrospective study. Patient demographics, surgical characteristics, as well as medical and reconstructive outcomes, were evaluated. The operative outcomes between myocutaneous VL, cVLALT, and cVLTFL flap reconstructions were compared., Results: A total of 41 patients underwent chest wall reconstruction with a free myocutaneous VL (n = 25; 61%), cVLALT (n = 14; 34%), or cVLTFL Three acute flap thromboses occurred in the entire cohort (3/41, 7%), with one myocutaneous VL flap failing because of recurrent venous thrombosis during the salvage procedure. Total flap necrosis was seen in two cases (5%; VL flap: n = 1; cVLALT flap: n = 1), and partial flap necrosis in one VL flap (1/25, 4%) and in the distal ALT portion of three cVLALT flaps (3/14, 21%). No significant difference was seen between isolated VL and conjoined VL flaps regarding the partial (p = .28) or total flap necrosis rate (p = .9)., Conclusion: The free (conjoined) VL flap provides reliable outcomes for obliterating dead space achieving durable reconstruction of complex chest wall defects., (© 2024 Wiley Periodicals LLC.)

Large open chest wall wounds can be difficult to manage due to full-thickness tissue loss with underlying rib fractures and exposed lung parenchyma. Historically, the use of synthetic material has been discouraged in the traumatic setting with the concern that it may be associated with an increased risk of infection. We present 4 patients with large open injuries to the thorax-one from blunt and three from penetrating trauma. We describe our initial management followed by prompt surgical repair using biologic mesh, titanium rib spanning plates, and rotational tissue flaps with Z-plasty of the skin for definite closure. All patients did well post-operatively without complications or wound infections. With the appropriate management, we suspect there may be an advantage in performing immediate reconstruction and closure in large open thoracic injuries utilizing biologic mesh and titanium rib spanning plates with a lower risk of infection than previously believed., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Abstract The Ultrasound‐guided Erector Spinae Plane Block (US‐ESPB), used as an anesthesiological block, could represent a safe and effective alternative for thoracic wall surgery especially in fragile, obese patients and those with respiratory and/or hemodynamic problems.

Background: Chest wall surgery for the correction of pectus excavatum or pectus carinatum has gained increased interest in recent years. Adequate pain treatment, respiratory physiotherapy and early ambulation are key to improving the outcomes. Although thoracic epidural analgesia is highly effective, its safety is controversial, leading to extensive scrutiny and questioning of its role., Objectives: We hypothesise that thoracic epidural analgesia is effective and well tolerated to use in adolescents, with a high success rate and low pain scores., Design: Observational retrospective cohort study., Setting: All adolescent cases in a high-volume academic tertiary chest wall surgery centre between March 1993 and December 2017 were included., Patients: A total of 1117 patients aged from 12 to 19 years of age and receiving either Ravvitch, Nuss or Abramson chest wall reconstruction for pectus excavatum were identified in our institutional chest wall surgery database. After applying selection and exclusion criteria, 532 patients were included in the current analysis., Main Outcome Measures: The primary endpoint of this study was the safety of epidural analgesia, assessed by the incidence of acute adverse events. Secondary endpoints were block success rates using a specific novel definition, and analgesic efficacy using recorded postoperative pain scores., Results: More than 60% of patients experienced one or more adverse events. However, all events were minor and without consequences. No serious or long-term adverse events were detected. The success rate of thoracic epidural placement was 81%. Low postoperative pain scores were observed., Conclusion: Thoracic epidural analgesia is an extremely effective pain control technique, with a surprisingly high number of minor adverse events but safe with regard to serious adverse events., Trial Registration: The local research ethics committee approved and registered this study on 16 May 2022 (registration number: S66594)., (Copyright © 2024 European Society of Anaesthesiology and Intensive Care.

Objectives: Both superficial and deep serratus anterior plane (SAP) blocks are effective for anterior chest wall surgeries, but there is little clarity on which is more effective. Hence, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the comparative efficacy of the 2 approaches for SAP block after anterior chest wall surgery., Materials and Methods: A systematic literature search was performed using PubMed, Embase, Scopus, and Cochrane Central Registers of Controlled Trials for eligible RCTs from inception until August 2023. The primary outcome was opioid consumption during the first 24 hours of the postoperative period. The secondary outcomes included pain scores at various intervals, intraoperative opioid consumption, time to first analgesic request, block-related complications, opioid-related side effects, and patient satisfaction scores. Statistical analysis of the pooled data was performed using Review Manager Version 5.3., Results: We identified 7 RCTs published between 2020 and 2022, enrolling 371 patients (186 in the superficial SAP block and 187 in the deep SAP block). Moderate certainty of evidence suggests that both the approaches (deep and superficial) of SAP block were comparable for 24-hour oral morphine equivalent consumption with a mean difference (MD) of 3.78 mg (95% CI: -1.70 to 9.29; P = 0.18; I2 = 87%). The results of other secondary outcomes were comparable, including resting pain scores with an MD of 0.08 (95% CI: -0.27 to 0.43; P = 0.67; I2 = 87%) for early pain and MD of 0.63 (95% CI: -1.28 to 0.01; P = 0.05; I2 = 95%) for late pain scores, time to first analgesic request with MD of -0.41 hour (95% CI: -1.40 to 0.59; P = 0.42; I2 = 90%), and incidence of postoperative nausea and vomiting (odds ratio: 1.45 (95% CI: 0.72 to 2.90; P = 0.30; I2 = 0%)., Conclusion: Current evidence does not support the preference for one approach of SAP block over the other for postoperative pain. Based on the available data, we recommend further future trials to determine any differences between these interventions., Competing Interests: The authors declare no conflict of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Pulmonary mucormycosis is a rare, life-threatening fungal infection usually seen in immunocompromised patients. Mortality in such patients is high due to underlying immunosuppression and poor general condition of the patients. Invasion of the adjacent structures is known but, to the best of our knowledge, pulmonary mucormycosis presenting with a full thickness chest wall erosion has not been reported. We report such a case with chest wall destruction with superadded bacterial infection. The use of prosthetic materials for chest wall reconstruction was not possible due to the presence of infection. In addition, there were other intra-operative and post-operative challenges which we managed using a multidisciplinary approach. This report highlights the successful outcome of this complex situation using pre-operative optimisation, adequate surgical debridement and effective management of post-operative complications with patience and perseverance., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Background: Malignant chest wall tumors need to be excised with wide resection to ensure tumor free margins, and the reconstruction method should be selected according to the depth and dimensions of the tumor. Vascularized tissue is needed to cover the superficial soft tissue defect or bone tissue defect. This study evaluated differences in complications according to reconstruction strategy., Methods: Forty-five patients with 52 operations for resection of malignant tumors in the chest wall were retrospectively reviewed. Patients were categorized as having superficial tumors, comprising Group A with simple closure for small soft tissue defects and Group B with flap coverage for wide soft tissue defects, or deep tumors, comprising Group C with full-thickness resection with or without mesh reconstruction and Group D with full-thickness resection covered by flap with or without polymethyl methacrylate. Complications were evaluated for the 52 operations based on reconstruction strategy then risk factors for surgical and respiratory complications were elucidated., Results: Total local recurrence-free survival rates in 45 patients who received first operation were 83.9% at 5 years and 70.6% at 10 years. The surgical complication rate was 11.5% (6/52), occurring only in cases with deep tumors, predominantly from Group D. Operations needing chest wall reconstruction (p = 0.0016) and flap transfer (p = 0.0112) were significantly associated with the incidence of complications. Operations involving complications showed significantly larger tumors, wider areas of bony chest wall resection and greater volumes of bleeding (p < 0.005). Flap transfer was the only significant predictor identified from multivariate analysis (OR: 10.8, 95%CI: 1.05-111; p = 0.0456). The respiratory complication rate was 13.5% (7/52), occurring with superficial and deep tumors, particularly Groups B and D. Flap transfer was significantly associated with the incidence of respiratory complications (p < 0.0005). Cases in the group with respiratory complications were older, more frequently had a history of smoking, had lower FEV1.0% and had a wider area of skin resected compared to cases in the group without respiratory complications (p < 0.05). Preoperative FEV1.0% was the only significant predictor identified from multivariate analysis (OR: 0.814, 95%CI: 0.693-0.957; p = 0.0126)., Conclusions: Surgical complications were more frequent in Group D and after operations involving flap transfer. Severe preoperative FEV1.0% was associated with respiratory complications even in cases of superficial tumors with flap transfer., (© 2024. The Author(s).)

Background: Surgical treatment of pediatric chest wall tumors requires accurate surgical planning and tumor localization to achieve radical resections while sparing as much healthy tissue as possible. Augmented Reality (AR) could facilitate surgical decision making by improving anatomical understanding and intraoperative tumor localization. We present our clinical experience with the use of an AR system for intraoperative tumor localization during chest wall resections. Furthermore, we present the pre-clinical results of a new registration method to improve our conventional AR system., Methods: From January 2021, we used the HoloLens 2 for pre-incisional tumor localization during all chest wall resections inside our center. A patient-specific 3D model was projected onto the patient by use of a five-point registration method based on anatomical landmarks. Furthermore, we developed and pre-clinically tested a surface matching method to allow post-incisional AR guidance by performing registration on the exposed surface of the ribs., Results: Successful registration and holographic overlay were achieved in eight patients. The projection seemed most accurate when landmarks were positioned in a non-symmetric configuration in proximity to the tumor. Disagreements between the overlay and expected tumor location were mainly due to user-dependent registration errors. The pre-clinical tests of the surface matching method proved the feasibility of registration on the exposed ribs., Conclusions: Our results prove the applicability of AR guidance for the pre- and post-incisional localization of pediatric chest wall tumors during surgery. The system has the potential to enable intraoperative 3D visualization, hereby facilitating surgical planning and management of chest wall resections., Level of Evidence: IV TYPE OF STUDY: Treatment Study., (Copyright © 2024 The Authors.

Anterior chest wall instability as a result of sternocostal non-union is a rare complication but can give rise to invalidating pain and cardiac arrhythmias. A woman in her 40s was referred to us with anterior chest wall pain and instability after a modified Ravitch procedure. Sternocostal pseudoarthrosis was seen for which multiple operations were performed which were complicated by low-grade infections. A patient-specific three-dimensional modelled and printed prostheses was used in an operation to both lift the sternum for pectus correction and to reconnect the sternum and the sternal costal junction to regain anterior chest wall stability., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Ewing sarcoma (ES) represents the second most common primary osseous malignancy in children and young adults, most often occurring in the diaphysis of the long bones. While rare, ES can present as an osseous tumor of the ribs and/or chest wall. These tumors are known as Askin's tumors and most commonly present with symptoms resembling pneumonia. We report the case of a 26-year-old man who was found to have a right lung mass extending into his anterolateral chest wall after presenting to the hospital for evaluation of unremitting chest pain. Biopsy was performed and the patient diagnosed with ES. After completion of neoadjuvant chemotherapy, the patient underwent resection of the right chest wall mass. The chest wall was reconstructed in a novel fashion with titanium plates and a reinforced tissue matrix patch. Due to a paucity of cases, no treatment or reconstruction algorithm currently exists for management of these malignancies., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The advent of propeller flaps has permitted new and less invasive coverage solutions for thoracic defects compared to conventional flaps. Through a retrospective analysis of our cases, we would like to show the advantages of the internal mammary artery perforator (IMAP) flap for anterior chest wall reconstruction., Methods: We included patients who underwent anterior chest wall reconstruction with an IMAP propeller flap in the Toulouse University Hospital's plastic surgery department from January 2019 to December 2022. The data were collected on patient data, skin defects, and flap characteristics., Results: Twenty-three IMAP flaps were realized to cover locoregional defects. The skin paddle size of the IMAP flap averaged 15.6cm long (12-20)×6.7cm wide (4-10). The average arc of rotation of the flap was 113.5° (range 70-140°). In 3 cases, the IMAP flap was performed with a superior epigastric artery perforator flap (SEAP). In 3 cases out of 23, the flap partially necrotized, requiring surgical revision. In 1 case, the flap was fully necrotized and had to be removed., Discussion and Conclusion: Our series of 23 IMAP flaps on thoracic reconstruction is one of the largest published to date. Our series shows that the IMAP flap offers a simple and reliable solution with minor donor site morbidity for reconstructing small to medium-sized defects in the medial and paramedian regions of the chest wall., (Copyright © 2024 Elsevier Masson SAS.

Background: Autologous costal cartilage has gained widespread acceptance as an important material for ear reconstruction in patients with microtia. Despite its recognition as being "worth the trade-off," attention should be directed toward donor-site deformities. This systematic review focused on existing English literature related to microtia reconstruction and aimed to reveal the incidence of chest wall deformities and assess the effectiveness of the various proposed surgical techniques aimed at reducing donor-site morbidities., Methods: A comprehensive search was conducted on Pubmed and OVID using the keywords "microtia," and "chest deformity" or "rib harvest." Articles were screened based on predefined inclusion and exclusion criteria. Data acquisition encompassed patient demographics, employed surgical techniques, methods for evaluating chest deformity, and incidence of associated complications., Results: Among the 362 identified articles, 21 met the inclusion criteria. A total of 2600 cases involving 2433 patients with microtia were analyzed in this review. Perichondrium preservation during cartilage harvesting led to a significant reduction in chest deformities. However, the wide incidence range (0% to 50%) and the lack of specific assessment methods suggested potential underestimation. Computed tomography revealed reduced chest wall growth in the transverse and sagittal directions, resulting in decreased thoracic area. Innovative surgical techniques have shown promising results in reducing chest deformities., Conclusions: Although a quantitative analysis was not feasible, objective evidence of deformities was established through computed tomography scans. This analysis highlighted the need for dedicated studies with larger sample sizes to further advance our understanding of chest wall deformities in microtia reconstruction., Competing Interests: Conflicts of interest We declare no conflicts of interest., (Copyright © 2024.

Introduction: To date, only a limited number of case reports have documented the co-occurrence of PNS and melanocytic nevus in the medical literature. This study aims to report an exceptionally rare case of posterior chest wall PNS in conjunction with a melanocytic nevus., Case Presentation: A 46-year-old female presented with a long-standing black lesion on her left upper posterior chest wall, that had become painful in the two months prior to presentation. There was a painful, dark blue, non-erythematous, and non-tender nodule on the left upper posterior chest wall. Based on the patient's desire for cosmetic purposes, the lesion was excised totally with primary closure under local anaesthesia. Histopathological examination revealed intradermal melanocytic nevus with inflamed pilonidal sinus., Discussion: The rarity of posterior chest wall PNS associated with nevi poses unique diagnostic and therapeutic challenges for clinicians. The distinct anatomical location, different from the conventional region, and the rare association between the two conditions may delay accurate diagnosis and result in mismanagement or inappropriate interventions., Conclusion: The posterior chest wall PNS is another type of atypical PNS that is extremely rare. The association between PNS and blue nevus is a fascinating medical finding that deserves further investigation., (© 2024. The Author(s).)

Background: Chest wall tumors are a heterogeneous group of tumors that are managed by surgeons from diverse specialties. Due to their rarity, there is no consensus on their diagnosis and management., Materials: This retrospective, descriptive analysis includes patients with malignant chest wall tumors undergoing chest wall resection. Tumors were classified as primary, secondary, and metastatic tumors. The analysis includes clinicopathological characteristics, resection-reconstruction profile, and relapse patterns., Results: A total of 181 patients underwent chest wall resection between 1999 and 2020. In primary tumors (69%), the majority were soft tissue tumors (59%). In secondary tumors, the majority were from the breast (45%) and lung (42%). Twenty-five percent of patients received neoadjuvant chemotherapy, and 98% of patients underwent R0 resection. Soft tissue, skeletal + soft tissue, and extended resections were performed in 45%, 70%, and 28% of patients, respectively. The majority of patients (60%) underwent rib resections, and a median of 3.5 ribs were resected. The mean defect size was 24 cm 2 . Soft tissue reconstruction was performed in 40% of patients, mostly with latissimus dorsi flaps. Rigid reconstruction was performed in 57% of patients, and 18% underwent mesh-bone cement sandwich technique reconstruction. Adjuvant radiotherapy and chemotherapy were given to 29% and 39% of patients, respectively., Conclusions: This is one of the largest single-institutional experiences on malignant chest wall tumors. The results highlight varied tumor spectra and multimodality approaches for optimal functional and survival outcomes. In limited resource setting, surgery, including reconstructive expertise, is very crucial., (© 2023. Society of Surgical Oncology.)

Chest-wall perforator-based techniques to replace volume for breast conservative therapy allow excision of large breast areas with minimal sequalae, such as the nipple-areolar complex displacement, parenchymal indentation or contour deformity. Furthermore, chest wall perforator flaps facilitate the maintenance of breast symmetry, hence decreasing the need for contralateral surgery. Lateral intercostal flap was described in numerous variants among which the most famous are the propeller flap and the turnover version. The turnover version is the easiest and fastest version that allows the replacement of large amount of volume. In this paper, we evaluate patients reported outcomes, before and after surgery, collected through the Breast Q. This study was conducted on 21 patients who were admitted to the plastic surgery department. A prospectively maintained database was used to identify the patients and their records were assessed retrospectively. The pre/post operative patients data were collected. The Breast-Q questionnaire was administered before the surgery and at least 1 year after. No major surgical complications were reported. Mean Breast-Q scores were evaluated at least 1 year after surgery and radiotherapy and compared with pre-surgical scores. Among all the modules, no significant differences between the pre-surgical and post-surgical Breast-Q scores were observed. Until now, the lateral intercostal artery perforator flap has not been widely used, due to a difficult dissection and a challenging preoperative planning. According to the reported surgical technique, the execution is easy. This technique provides the same breast-related quality of life compared to preoperative values, reduces the mastectomy rate and increases the overall survival., (© 2023.

Background: Chest-wall sarcomas are treated with extensive resections and complex defect reconstruction to restore chest-wall integrity. It is a difficult surgical procedure that incorporates a multidisciplinary approach for the best outcome, preventing paradoxical chest movement issues and reducing complications., Objective: We aimed to describe our experience of chest-wall reconstruction using polypropylene mesh (Marlex® Mesh) combined with methyl-methacrylate and soft-tissue coverage with a latissimus dorsi flap following sarcoma resection., Patients and Methods: Among the 53 patients treated for primary chest-wall sarcomas at the European Institute of Oncology (IEO) in Milan, Italy, from 1998 to 2020, 14 cases underwent chest-wall resection and reconstruction using polypropylene mesh, methyl-methacrylate and the latissimus dorsi flap. Patients with locally advanced breast cancers, locally advanced lung cancers, squamous cell carcinomas, and other secondary chest-wall malignancies were excluded from the study, as were the patients with different types of chest-wall reconstruction., Results: In this study, 14 patients (6 men and 8 women) with various primary chest-wall sarcomas were enrolled. On an average, 2 ribs (range: 1-5) were removed during the surgeries, and the chest-wall defects ranged from 20 to 150 cm 2 with an average size of 73 cm 2 . The mean follow-up period for these patients was approximately 63.80 months CONCLUSION: The combination of Marlex® mesh filled with methyl-methacrylate and covered using latissimus dorsi myocutaneous flap provides safe, low-cost and effective single-stage chest-wall reconstruction after surgery for primary sarcomas., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background: Pectus arcuatum, also known as horns of steer anomaly or Currarino-Silverman Syndrome, is a distinct chest wall anomaly characterized by severe manubriosternal angulation, a shortened sternum, and mild pectus excavatum. The anomaly is typically repaired using open techniques, employing orthopedic fixation devices. Here, we report the results of a minimally invasive hybrid procedure to repair pectus arcuatum., Methods: The procedure combines a standard Nuss procedure to correct the depressed sternum with a short upper chest (in boys) or inter-mammary (in girls) incision for bilateral subperichondrial resection of the upper costal cartilages, osteotomy, and correction of the manubrial angulation. The medical records of all patients who underwent the procedure over the last 10 years were reviewed., Results: Five patients, 3 boys and 2 girls, aged 14 to 17 years, underwent the procedure. Three patients had their pectus bars removed 3-4 years after repair. Follow-up after correction ranged from 6 months to 7 years. Good correction resulted in all patients achieving recovery without complications and recurrence. To date, all patients have been satisfied with their results., Conclusions: The minimally invasive hybrid procedure adequately corrects pectus arcuatum with minimal scarring and high satisfaction., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background and Objectives : Chest wall defect reconstruction is a complex procedure aimed at restoring thoracic structural integrity after trauma, tumor removal, or congenital issues. In this study, postoperative complications were investigated to improve the care of patients with these critical conditions. Materials and Methods : A retrospective study of chest wall reconstructions from 2004 to 2023 was conducted at Klinikum Nürnberg and Evangelisches Waldkrankenhaus Spandau-Berlin. Data included patient demographics, comorbidities, defect etiology, surgery details, and complications using the Clavien-Dindo classification. Results : Among the 30 patients included in the study, a total of 35 complications occurred in 35 thoracic wall defect reconstructions. These complications were classified into 22 major and 13 minor cases. Major complications were more common in patients with cancer-related defects, and considerable variations were observed between free flap and pedicled flap surgeries. Notably, the use of the anterolateral thigh (ALT) flap with vastus lateralis muscle demonstrated promise, exhibiting fewer complications in select cases. The reconstruction of chest wall defects is associated with substantial complications regardless of the etiology of the defect and the particular surgical procedure used. Interestingly, there was a lower complication rate with free flap surgery than with pedicled flaps. Conclusions : The ALT flap with vastus lateralis muscle deserves further research in this field of reconstruction. Multidisciplinary approaches and informed patient discussions are crucial in this complex surgical field, emphasizing the need for ongoing research and technique refinement.

Background and Objectives: As one of the cutting-edge advances in the field of reconstruction, three-dimensional (3D) printing technology has been constantly being attempted to assist in the reconstruction of complicated large chest wall defects. However, there is little literature assessing the treatment outcomes of 3D printed prostheses for chest wall reconstruction. This study aimed to analyze the surgical outcomes of 3D custom-made prostheses for the reconstruction of oncologic sternal defects and to share our experience in the surgical management of these rare and complex cases., Methods: We summarized the clinical features of the sternal tumor in our center, described the surgical techniques of the application of 3D customized prosthesis for chest wall reconstruction, and analyzed the perioperative characteristics, complications, overall survival (OS), and recurrence-free survival of patients., Results: Thirty-two patients with the sternal tumor who underwent chest wall resection were identified, among which 13 patients used 3D custom-made titanium implants and 13 patients used titanium mesh for sternal reconstruction. 22 cases were malignant, and chondrosarcoma is the most common type. The mean age was 46.9 years, and 53% (17/32) of the patients were male. The average size of tumor was 6.4 cm, and the mean defect area was 76.4 cm 2 . 97% (31/32) patients received R0 resection. Complications were observed in 29% (9/32) of patients, of which wound infection (22%, 7/32) was the most common. The OS of the patients was 72% at 5 years., Conclusion: We demonstrated that with careful preoperative assessment, 3D customized prostheses could be a viable alternative for complex sternal reconstruction., (© 2024 Wiley Periodicals LLC.)

Objective: There can be anatomical constraints on patient selection for minimally invasive surgery. For example, robot-assisted coronary artery bypass was reported to be more challenging when patients had a cardiothoracic ratio >50% and a sternum-vertebra anteroposterior and transverse diameter ratio <0.45. We sought to examine the impact of chest wall anatomic parameters on surgical outcomes in our totally endoscopic coronary artery bypass (TECAB) procedures., Methods: We retrospectively reviewed patients who underwent robotic TECAB, all of whom had a preoperative chest radiograph at our institution from July 2017 to October 2021. The cohort was divided into 2 groups, which were patients undergoing single-vessel grafting using the left internal thoracic artery (ITA; group 1) and patients undergoing multivessel grafting with bilateral ITA grafts (group 2). We measured several anatomical parameters from the preoperative chest radiograph., Results: A total of 352 patients undergoing TECAB were retrospectively analyzed. After exclusions, 193 were included in this study. In group 1 ( n = 91), no parameters correlated with operative time. In group 2 ( n = 102), a significant negative correlation was observed between operative time and the sternum-vertebrae anteroposterior diameter ( r s = -0.228, P = 0.022) and lung anteroposterior diameter ( r s = -0.246, P = 0.013). To confirm these results in group 2, a propensity-matched analysis was performed and showed a statistically significant difference in surgical time based on chest anteroposterior diameters., Conclusions: In single-vessel robotic TECAB, chest wall anatomic dimensions measured on chest radiograph did not affect operative time. In multivessel cases with bilateral ITA grafts, larger anteroposterior diameter correlated with shorter operative times., Competing Interests: Declaration of Conflicting InterestsThe authors declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Husam Balkhy is a proctor for Intuitive, maker of the da Vinci robot.

Background: There are various reconstructive methods after total sternectomy. Reproducibility is scarce due to overall small patient numbers. Therefore we present a standardized, interdisciplinary approach for thoracic and plastic surgery., Methods: Four patients underwent interdisciplinary chest wall reconstruction with STRATOS® titanium bars and myocutaneous vastus lateralis muscle free flap in our center., Results: All patients reported chest wall stability after reconstruction. They reported good quality of life, no dyspnea, prolonged pain or impairment in lung function from rigid reconstruction. FEV1/FVC was overall better after surgery. Secondary wound healing was not impaired and there was no implant defect in follow up., Conclusions: We recommend an interdisciplinary surgical approach in chest wall reconstruction after total sternectomy. The combination of rigid reconstruction with titanium bars and a myocutaneous vastus lateralis muscle free flap renders excellent results in patient satisfaction and is objectifiable via spirometry., (© 2024.

Background: Very large chest wall resections can lead to acute thoracic insufficiency syndrome due to the interdependence of lung expansion and thoracic volume. Chest wall tumor surgeries often encounter complications, with the size of the chest wall defect being a significant predictor. Several methods for large chest wall reconstruction have been described, aiming to provide stability, prevent flail chest, and ensure airtight closure. However, no single method fulfills all requirements. Composite chest wall reconstruction using titanium plates and Gore-Tex patches has shown the potential to minimize physiologic abnormalities caused by extensive defects., Case Presentation: A 42-year-old man with myxofibrosarcoma underwent multiple surgeries, chemotherapies, and radiation therapies due to repeated local recurrences. After right arm amputation and resection of the right third to fifth ribs, a local recurrence was detected. A 30 × 40 cm chest wall defect was resected en bloc, and a titanium plate was used for three-dimensional formability, preventing flail chest and volume loss. The Gore-Tex patch was then reconstructed into an arch shape, allowing lateral thoracic mobility. The patient recovered well and did not experience respiratory dysfunction or local recurrence but later succumbed to distant metastasis., Conclusions: In this case, the combination of a titanium plate and a Gore-Tex patch proved effective for reconstructing massive lateral chest wall defects. The approach provided stability, preserved thoracic volume, and allowed for lateral mobility. While the patient achieved a successful outcome in terms of local recurrence and respiratory function, distant metastasis remained a challenge for myxofibrosarcoma patients, and its impact on long-term prognosis requires further investigation. Nevertheless, the described procedure offers promise for managing extensive chest wall defects., (© 2024. The Author(s).)

Background: Over the last two decades, the acute management of rib fractures has changed significantly. In 2021, the Chest Wall injury Society (CWIS) began recognizing centers that epitomize their mission as CWIS Collaborative Centers. The primary aim of this study was to determine the resources, surgical expertise, access to care, and institutional support that are present among centers., Methods: A survey was performed including all CWIS Collaborative Centers evaluating the resources available at their hospital for the treatment of patients with chest wall injury. Data about each chest wall injury center care process, availability of resources, institutional support, research support, and educational offerings were recorded., Results: Data were collected from 20 trauma centers resulting in an 80% response rate. These trauma centers were made up of 5 international and 15 US-based trauma centers. Eighty percent (16 of 20) have dedicated care team members for the evaluation and management of rib fractures. Twenty-five percent (5 of 20) have a dedicated rib fracture service with a separate call schedule. Staffing for chest wall injury clinics consists of a multidisciplinary team: with attending surgeons in all clinics, 80% (8 of 10) with advanced practice providers and 70% (7 of 10) with care coordinators. Forty percent (8 of 20) of centers have dedicated rib fracture research support, and 35% (7 of 20) have surgical stabilization of rib fracture (SSRF)-related grants. Forty percent (8 of 20) of centers have marketing support, and 30% (8 of 20) have a web page support to bring awareness to their center. At these trauma centers, a median of 4 (1-9) surgeons perform SSRFs. In the majority of trauma centers, the trauma surgeons perform SSRF., Conclusion: Considerable similarities and differences exist within these CWIS collaborative centers. These differences in resources are hypothesis generating in determining the optimal chest wall injury center. These findings may generate several patient care and team process questions to optimize patient care, patient experience, provider satisfaction, research productivity, education, and outreach., Level of Evidence: Therapeutic/Care Management; Level V., (Copyright © 2023 Wolters Kluwer Health, Inc.

Aims: To evaluate Patient Reported Outcome Measures (PROMs) and surgical outcomes in patients undergoing Chest Wall Perforator Flaps (CWPFs)., Methods: This was an observational single cohort study using an audit approach and a survey instrument. 84 patients who had undergone CWPFs in the last 5 years at the Department of Breast Surgery, City Hospital Birmingham, were identified from a pre-existing database. Surgical outcomes were recorded. Patients were contacted telephonically or in person at the time of follow-up and were asked to fill up a PROMs questionnaire., Results: Out of 84 patients, 58 patients chose to respond. The average age of the patients was 51.3 years (±8.2 years). The average follow-up was 15.4 months (±9.9 months). The most common histological subtype was Infiltrating ductal carcinoma (IDC)-Not otherwise specified 34/58 (58.6%). Majority of the patients had T2 cancers-28/58 (48.3%). 26/58 (44.8%) were node negative. Eight patients (13.7%) had post-operative complications. No patient had total/partial flap loss. Nine patients (15.5%) had margin re-excision. One patient developed distant metastasis while 1 patient developed a second primary. Fifty-one patients (88%) were either satisfied or very satisfied with the post-operative appearance of the breasts. Thirty-six patients (62%) had no/little persistent pain or tenderness post-surgery. Eighty-six per cent (38/44) of the patients undergoing Lateral Intercostal Artery Perforator (LICAP) Flap and 16/18 (89%) of patients undergoing Anterior Intercostal Artery Perforator (AICAP) flap had no/little difficulty in carrying out normal activities at follow up., Conclusion: CWPFs are associated with a low complication rate and a high patient satisfaction rate., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Purpose: Surgical stabilization of rib fractures (SSRF) improves outcomes in certain patient populations. The Chest Wall Injury Society (CWIS) began a new initiative to recognize centers who epitomize their mission as CWIS Collaborative Centers (CWIS-CC). We sought to describe incidence and epidemiology of SSRF at our institutions., Methods: A retrospective registry evaluation of all patients (age > 15 years) treated at international trauma centers from 1/1/20 to 7/30/2021 was performed. Variables included: age, gender, mechanism of injury, injury severity score, abbreviated injury severity score (AIS), emergency department disposition, length of stay, presence of rib/sternal fractures, and surgical stabilization of rib/sternal fractures. Classification and regression tree analysis (CART) was used for analysis., Results: Data were collected from 9 centers, 26,084 patient encounters. Rib fractures were present in 24% (n = 6294). Overall, 2% of all patients underwent SSRF and 8% of patients with rib fractures underwent SSRF. CART analysis of SSRF by AIS-Chest demonstrated a difference in management by age group. AIS-Chest 3 had an SSRF rate of 3.7, 7.3, and 12.9% based on the age ranges (16-19; 80-110), (20-49; 70-79), and (50-69), respectively (p = 0.003). AIS-Chest > 3 demonstrated an SSRF rate of 9.6, 23.3, and 39.3% for age ranges (16-39; 90-99), (40-49; 80-89), and (50-79), respectively (p = 0.001)., Conclusion: Anticipated rate of SSRF can be calculated based on number of rib fractures, AIS-Chest, and age. The disproportionate rate of SSRF in patients age 50-69 with AIS-Chest 3 and age 50-79 with AIS-Chest > 3 should be further investigated, as lower frequency of SSRF in the other age ranges may lead to care inequalities., (© 2023.

Background: Usually, pectus bars are removed 3 years after the Nuss procedure in patients with pectus excavatum. However, the optimal timing for postoperative pectus bar removal remains undefined. Our study investigated the effects of delayed pectus bar removal after Nuss repairs., Methods: Retrospective data were collected on patients who underwent Nuss procedures for pectus excavatum and had their bars removed from August 2014 to December 2020. Patients with correction periods > 3 years were divided into group A (< 6 years) and group B (≥ 6 years). Propensity score matching was used to compare complications and radiological outcomes associated with bar removal., Results: Of the 542 patients who underwent bar removal, 451 (Group A: 419 patients, Group B: 32) had correction duration > 3 years. The average correction duration was 4.5 ± 1.4 years. After propensity score matching analysis, group B [median duration: 8.0 (6.0-16.2) years] exhibited significantly longer median operative times (85 vs. 55 min; P = 0.026), higher callus formation rates (68.8% vs. 46.9%; P = 0.029), and greater median intraoperative blood loss (35 vs. 10 mL; P = 0.017) than group A [median duration: 4.2 (3.0-5.9) years]. However, following bar removal, the groups showed no statistical differences in the surgical complication rates (group A: 6.3% vs. group B: 9.4%; P = 0.648) or median ratio of radiological improvement (an improvement on the Haller index on chest radiography; 21.0% vs. 22.2%; P = 0.308)., Conclusions: Delaying pectus bar removal after Nuss repair presents certain challenges but does not compromise overall outcomes. These findings suggest that a longer correction period may be unnecessary. However, further multicenter studies with long-term follow-up are warranted to assess long-term outcomes., (© 2024.

Background: Chest wall chondrosarcomas, although common, pose unique challenges due to their aggressive nature, rarity of abdominal wall involvement, and propensity for recurrence. We highlight the critical role of meticulous surgical planning, multidisciplinary collaboration, and innovative reconstruction techniques in achieving optimal outcomes for patients with composite giant chest and abdominal wall chondrosarcoma., Case Presentation: A 38-year-old female patient presented with progressive left chest and abdominal wall swelling for two years; on evaluation had a large lobulated lytic lesion arising from the left ninth rib, scalloping eighth and tenth ribs measuring 13.34 × 8.92 × 10.71 cm (anteroposterior/transverse/craniocaudal diameter) diagnosed with chondrosarcoma grade 2. A three-dimensional (3D) composite mesh was designed based on computed tomography using virtual surgical planning and computer-assisted design and manufacturing technology. She underwent wide local excision and reconstruction of the chest and abdominal wall with 3D-composite mesh under general anesthesia. The postoperative condition was uneventful, with no recurrence at 12 months follow-up., Conclusion: A 3D-composite mesh facilitates patient-specific, durable, and cost-effective chest and abdominal wall reconstruction., (© 2024.

In the majority of cases implosion injuries to the thoracic wall are caused by blunt, massive force acting on the thorax. Basically, different regions and directions of the acting energy have to be taken into account. In common usage, the term implosion injury has become established, especially for the sequelae of lateral energy impact. Particular attention should be paid to the stability of the shoulder girdle, the underlying hemithorax and its intrathoracic organs., (© 2024.

Thoracotomy is defined as an incision made by the surgeon in the chest wall in order to allow visibility of the thoracic cavity content. This can be used by surgeons to treat thoracic cavity content diseases including the heart, lungs, esophagus, and other organs. Thoracic incision closure remains an item with no consensus. Therefore, we present an easy way and give a little tip for closure using the slipknot that will allow the correct approach of ribs and the successful closure of the intercostal space., Competing Interests: None declared., (Thieme.

Background: Often missed in blunt chest wall injury, costal cartilage injuries can cause chest wall instability, refractory pain, and deformity. Notably, there is only a small amount of evidence regarding hardware performance when applied to costal cartilage. In a prior multicenter study, hardware failure rate was found to be approximately 3% following surgical stabilization of rib fractures (SSRFs) for all fracture locations. The aim of the current study was to evaluate hardware performance for costal cartilage injuries., Methods: All patients undergoing SSRF performed at our institution from 2016 to 2022 were queried, including both acute and chronic injuries. Both radiographic and clinical follow-up were retrospectively reviewed to evaluate for hardware failure defined as plate fracture, malposition, or screw migration following cartilage fixation., Results: After screening 359 patients, 43 were included for analysis. Mean age was 64 years, and 67% of patients were male. Median number of fractures per patient was 7 with 60% of patients sustaining a flail chest injury pattern. Median total plates per operation was 6 and median costal cartilage plates was 3. In total, 144 plates were applied to the costal cartilage for the group. Mean follow-up was as follows: clinical 88 days, two-view plain radiography 164 days, and chest computed tomography 184 days. Hardware failure was observed in 3 of 144 plates (2.1%), in three separate patients. Two cases were asymptomatic and did not require intervention. One patient required revisional operation in the acute setting., Conclusion: In our institution, hardware failure for costal cartilage fractures was observed to be 2.1%. This aligns with prior reports of hardware failure during SSRF for all injury locations. Surgical stabilization of anterior and cartilaginous chest wall injury with appropriate plate contouring and fixation technique appears to provide adequate stabilization with a relatively low rate of hardware malfunction., Level of Evidence: Therapeutic/Care Management; Level V., (Copyright © 2023 Wolters Kluwer Health, Inc.

Traumatic injuries of the thorax can entail thoracic wall instability (flail chest), which can affect both the shape of the thorax and the mechanics of respiration; however, so far little is known about the biomechanics of the unstable thoracic wall and the optimal surgical fixation. This review article summarizes the current state of research regarding experimental models and previous findings. The thoracic wall is primarily burdened by complex muscle and compression forces during respiration and the mechanical coupling to spinal movement. Previous experimental models focused on the burden caused by respiration, but are mostly not validated, barely established, and severely limited with respect to the simulation of physiologically occurring forces. Nevertheless, previous results suggested that osteosynthesis of an unstable thoracic wall is essential from a biomechanical point of view to restore the native respiratory mechanics, thoracic shape and spinal stability. Moreover, in vitro studies also showed better stabilizing properties of plate osteosynthesis compared to intramedullary splints, wires or screws. The optimum number and selection of ribs to be fixated for the different types of thoracic wall instability is still unknown from a biomechanical perspective. Future biomechanical investigations should simulate respiratory and spinal movement by means of validated models., (© 2023.

Every year ca. 60,000 people in Germany undergo cardiopulmonary resuscitation (CPR). The two most frequent underlying causes are of cardiopulmonary and traumatic origin. According to the current CPR guidelines chest compressions should be performed in the middle of the sternum with a pressure frequency of 100-120/min and to a depth of 5-6 cm. In contrast to trauma patients where different injury patterns can arise depending on the accident mechanism, both the type of trauma and the injury pattern are similar in patients after CPR due to repetitive thorax compression. It is known that an early reconstruction of the thoracic wall and the restoration of the physiological breathing mechanics in trauma patients with unstable thoracic injuries reduce the rates of pneumonia and weaning failure and shorten the length of stay in the intensive care unit. As a result, it is increasingly being propagated that an unstable thoracic injury as a result of CPR should also be subjected to surgical treatment as soon as possible. In the hospital of the authors an algorithm was formulated based on clinical experience and the underlying evidence in a traumatological context and a surgical treatment strategy was designed, which is presented and discussed taking the available evidence into account., (© 2023.

The impact of energy on the thorax can lead to serial rib fractures, sternal fractures, the combination of both and to injury of intrathoracic organs depending on the type, localization and intensity. Sometimes this results in chest wall instability with severe impairment of the respiratory mechanics. In the last decade the importance of surgical chest wall reconstruction in cases of chest wall instability has greatly increased. The evidence for a surgical approach has in the meantime been supported by prospective randomized multicenter studies, multiple retrospective data analyses and meta-analyses based on these studies, including a Cochrane review. The assessment of form and severity of the trauma and the degree of impairment of the respiratory mechanism are the basis for a structured decision on an extended conservative or surgical reconstructive strategy as well as the timing, type and extent of the operation. The morbidity (rate of pneumonia, duration of intensive care unit stay and mechanical ventilation) and fatality can be reduced by a timely surgery within 72 h after trauma. In this article the already established and evidence-based algorithms for surgical chest wall reconstruction are discussed in the context of the current evidence., (© 2024.

The Ultrasound‐guided Erector Spinae Plane Block (US‐ESPB), used as an anesthesiological block, could represent a safe and effective alternative for thoracic wall surgery especially in fragile, obese patients and those with respiratory and/or hemodynamic problems. [ABSTRACT FROM AUTHOR]

Background: Pectus excavatum (PE) is the most common congenital abnormality of the chest wall. Most patients with PE have slim bodies. Some studies have been conducted on the physical growth of children and adolescents who underwent the Nuss procedure. This study aimed to evaluate body measurement changes in adult patients with PE after the Nuss procedure., Methods: A total of 272 adult PE patients, who underwent the Nuss procedure and pectus bars removal from August 2014 to December 2020, were evaluated retrospectively. Body measurement [body height (BH), body weight (BW), and body mass index (BMI)] of the patients were collected before Nuss repair and after bar removal. We used the interquartile range (IQR) to identify and exclude outliers. Associations between changes in body measurement and clinical and radiological features were evaluated., Results: The BH, BW and BMI showed significantly increased after pectus bar removal, compared to pre-Nuss procedure parameters (BH 173.8 ± 5.9 cm vs. 173.9 ± 5.9 cm, P < 0.001; BW 60.3 ± 8.1 kg vs. 61.1 ± 8.8 kg, P = 0.005; BMI 19.9 ± 2.2 kg/m2 vs. 20.1 ± 2.4 kg/m2, P = 0.02). The same result were observed in the male subgroup, the HI ≥ 4 group and the male subgroup within the HI ≥ 4 group., Conclusions: The BH, BW and BMI were significantly increased after completing surgical correction of PE using the Nuss procedure, particularly in young males and patients with more pronounced deformities., (© 2024.

Foreign bodies fully embedded in soft tissues present a unique challenge to surgeons attempting excision. Small fragments can be nonpalpable, and many prove difficult to visualize intra-operatively by means of classic radiologic techniques. A 35-year-old active duty soldier presented requesting excision of ballistic fragment embedded in his chest wall that had previously failed a previous attempt at removal. The metallic foreign body was successfully localized intra-operatively using a handheld magnetometer probe and removed without complication. This case demonstrates the utility and cost-effectiveness of the handheld magnetometry for intra-operative localization of metallic foreign bodies. Metallic foreign bodies may be localized intra-operatively using inexpensive and reusable equipment that does not require radiation or bulky radiographic imaging equipment., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2023.
