A successful case of crossover replantation of the left foot to the stump of the right leg was described. The lower extremities were amputated at different levels. On the left side, there was a complete amputation in the distal part of the lower leg with comminuted fracture of the distal tibia. On the right side, there was a complete amputation in the hindfoot with comminuted fracture of both the talus and calcaneus. Since anatomical replantation was impossible, we performed crossover replantation of the left foot to the right lower leg. At the latest follow-up examination, forty-six months after the accident, the patient walked independently with a prosthesis on the stump of the left leg. Crossover replantation should be considered in bilateral amputations for the salvage of at least one extremity.

Summary: The aim of this review was to identify studies that used thromboelastography (TEG) or rotational thromboelastometry (ROTEM) in microsurgical free flap reconstruction and analyse whether it is a useful adjunct at predicting and identifying thrombotic complications.A search was conducted using the MEDLINE database using the keywords “thromboelastogram”, “TEG”, “thromboelastography”, “free flaps” and “free tissue transfer” using a two-component search with the Boolean operators “OR” and “AND”.Eight studies were retrieved using the search criteria. Seven studies met the inclusion criteria, and a further study was found citing several articles from the initial search. Combined, there were 528 patients who underwent 600 free flaps. A total of 10.3% (62) arterial and venous thromboses were reported in the studies, and the combined flap failure rate was 5.2% (26).A total of 67% (4/6) of the studies supported the use of TEG as a predictive tool to detect thromboses, including three retrospective case series and one prospective cohort, which were all statistically significant.There is low-quality evidence (level IV) that a pre-operative TEG and functional fibrinogen to platelet ratio of ≥42 can identify patients at risk of adverse post-operative thrombotic events following free flap surgery; however, further validation is required. Higher quality, standardised prospective or randomised control trials are required to further evaluate the predictive value of TEG. As a pre-operative screening tool, TEG can help to detect pathological changes in coagulation, aid in the transfusion of blood products, target anticoagulation therapy and predict possible adverse events aiding to further reduce patient morbidity.

Background: Mortality studies inform hospital disease trends and predict possible poor outcome. This study aimed to establish mortality trends over the last 5 years and the associated risk factors at the Kenyatta National Hospital (KNH) surgical operating theaters and to establish the completeness of surgical safety checklist. Methods: In this analytical retrospective study, study population was 94,820 patients operated between January 2015 and December 2019 and a sample of all 145 patients who died intraoperatively. Sampling was done by census. Data were extracted from available 118 deceased patients’ records and analyzed using Statistical Package for Social Sciences version 25. Results: Theater mortality rate was 0.153%. Sex-specific mortality rate was higher in males than in females (23.7 and 7.4 per 10,000, respectively). The mortality rate slowly declined over the period. The risk of death in theater was higher in neonates and in patients older than 80 years (54.3 and 39.2 per 10,000, respectively), emergency patients, and general anesthesia (p

Background: Upper gastrointestinal bleeding (UGIB) is a common indication for endoscopy. We aimed to describe the endoscopic findings in patients referred to our center with UGIB. Methods: This was a singlecenter retrospective study of the endoscopic findings in patients with UGIB between August 1, 2017, and April 30, 2019, in Lagos, Nigeria. Data were analyzed using Statistical Package for Social Sciences version 23.0.Results: Eight hundred thirty-two patients underwent endoscopy, of which 129 (16%) were for UGIB, which occurred twice as frequently in males. Melena was the most frequent presentation. Endoscopic abnormalities including gastric/duodenal peptic ulcers (39%),gastroduodenal erosions (36%), and varices (12%), were identified in 83% of the participants. Most ulcers were ow risk. Conclusion: Patients presenting to our center with UGIB commonly have gastric/duodenal peptic ulcers or gastroduodenal erosions.

Beckwith-Wiedemann Syndrome is a congenital disease that is rare and has low prevalence worldwide. It presents classically with features of macroglossia, abdominal wall defects (omphalocele), and macrosomia at birth. Other typical manifestations include facial nevus simplex, ear lobe abnormalities (creases and/or pits), transient hypoglycemia, and renal abnormalities seen on ultrasound. We report a case of a female preterm infant of twin gestation presenting at our level 4 hospital’s newborn unit with typical features of the syndrome. We aimed to create further awareness on the diagnosis in secondary health institutions and management of common features and complications of the syndrome. There is a paucity of pictorial evidence of morphology and literature related to the syndrome in an African child and this case report aims to improve that. No case has been previously reported in the Kenyan setting.

Background: Hydatidosis is a major health problem is many countries. It is a parasitic disease that can affect adults as well as children. Hydatid cyst often involves the lungs in children. Given the anatomical and physiological differences between children and adults, generalization from adult studies is inappropriate. Methods: To determine particularities of lung echinococcosis in children, we conducted a retrospective study of all cases treated for hydatid cyst of the lung at our department. Results: One hundred fifteen children (average age, 7 years 6 months; range, 3–15 years) were managed for pulmonary hydatid cyst, which corresponds to 66% of all hydatid localizations. Male predominance was noted (sex ratio=1.94). Cough (60.9%) and chest pain (59.1%) were the most common clinical features. Fever and fatigue were noted in 57 (49.5%) and 34 (29.5%) cases, respectively. Giant cysts were seen in 11 patients (10%). The cysts were mostlydiagnosed when they are intact (68.7%). Mixed hepatic and pulmonary cysts were noted in 27 cases (4.25%). Conservative muscle-sparing surgery was performed in all cases. Complications were noted in 20% of the cases. Conclusion: As hydatidosis has a different pattern in children, optimal management requires a better knowledge of its particularities in this age group.

Infection of prosthetic vascular grafts can manifest as pain, pseudoaneurysms, or arterial insufficiency in the leg. We present the case of a female patient with a medical history of a right external iliac artery endofibrosis, with a persistently infected synthetic iliofemoral bypass graft, which we replaced with a bioengineered human acellular vessel. At the 12-month follow-up visit, the clinical and radiologic studies demonstrated adequate human acellular vessel patency, with no signs of infection, stenosis, or pseudoaneurysm. Subsequent to the initiation of hormone therapy and cessation of antiplatelet therapy, the patient developed graft thrombosis. She continued to do well after restoration of patency with lytic therapy. At 22 months, secondary patency has been maintained with continued anticoagulation therapy, and the patient has remained asymptomatic.

In the treatment of retroperitoneal sarcoma involving major vessels, complete resection with vascular reconstruction is challenging. We describe the case of a 72-year-old man who presented with 8 months of abdominal pain. Diagnostic workup revealed occlusion of the celiac trunk and the origin of the superior mesenteric artery due to a soft tissue sarcoma. Radical resection of the tumor and vessels was performed. Guided by intraoperative angiography, arterial reconstruction was performed without mesenteric ischemia. All arterial margins were negative. At the 6-year follow-up, the patient was alive with no evidence of recurrence.

Subclavian artery aneurysms are rare peripheral artery aneurysms, and open surgical repair is the reference standard treatment. We have reported the case a patient with a right subclavian artery aneurysm who was not indicated for open surgical repair because of comorbidities. Thus, endovascular treatment using the Gore Excluder Iliac Branch Endoprosthesis (WL Gore and Associates, Flagstaff, Ariz) was performed, leading to complete aneurysmal exclusion without perioperative complications. Although anatomic limitations exist, this technique could be alternative treatment option for right subclavian artery aneurysms.

Background: Macrodactyly is a rare congenital disorder of overgrowth affecting the digits of the upper or lower extremity. Mostly, patients are surgically treated during childhood to reduce the digit or to stop growth. There are no standardized guidelines for the treatment and follow-up of macrodactyly. Consequently, follow-up may not be regularly scheduled into adulthood. Methods: A retrospective, descriptive analysis of patients with the long-term progression of macrodactyly who presented at our tertiary referral hospital between July 2018 and March 2020 was performed. All patients from our local macrodactyly database were screened for progression of macrodactyly since adulthood; this resulted in four patients. The aim of these case series is to highlight the clinical features and disease course at long-term follow-up. Results: All patients were surgically treated during childhood and showed progression of tissue overgrowth during adult life. All patients developed severe secondary degenerative bone changes in macrodactyly affected digits, such as ankyloses of joints, new bone formation, and bony spurs. Subsequently, tissue overgrowth and degenerative bone changes led to functional problems. Conclusion: Patients with macrodactyly may experience growth during adult life, which may progress to deforming changes. Consequently, patients should be informed about the possible growth, and the progressive growth should be monitored.

At present, no consensus has been reached regarding the optimal management of stent graft thrombosis in the femoropopliteal artery. We present a case of long thrombosis of a Viabahn stent graft implanted in the superficial femoral artery that was successfully treated by thrombectomy using a trans-Viabahn approach at the mid-thigh segment. The advantages of this approach include that it preserves the common femoral artery and popliteal artery untouched without scarring, allowing for a future site of surgical anastomosis. This technique could be a reasonable approach when performing surgical thrombectomy for stent graft thrombosis in the femoropopliteal artery.

Summary: Bullous pemphigoid (BP) is an autoimmune subepidermal blistering dermatological condition that can be triggered by several external factors. Here, we present a case of an immunocompetent patient with no prior dermatological history, who developed BP as a result of autologous skin graft surgery. It is an uncommon surgical complication and was most likely triggered by the trauma of the surgery itself.Our patient's bullae first developed a month after his surgery at both surgical sites and subsequently became widespread. The diagnosis was confirmed histologically using punch biopsies of a bulla and the perilesional skin for direct immunofluorescence together with indirect immunofluorescence of the serum for anti-skin antibodies. Initial topical treatment and regular wound care were not improving the patient's condition at a satisfactory rate. Therefore, the patient was started on systemic steroids, which unfortunately resulted in a presumed split skin graft infection requiring admission. After histological diagnosis confirmation was achieved, the Dermatology team formulated a treatment plan, which combined both topical and systemic medication. The patient is currently making a good recovery and the graft loss resulting from the condition is only partial, requiring no further surgery.We present this case as a reminder to all clinicians that, although rare, BP can be triggered by skin grafting, even in patients with no prior history of it or any predisposing conditions. This autoimmune condition needs to be recognised and treated promptly to ensure optimal clinical outcomes and minimise graft loss.

Cerebrospinal fluid drainage is recommended for high-risk patients to prevent spinal cord ischemia during aortic surgery; however, it is associated with complications. We report a case of a late-onset spinal subdural hematoma that developed after removal of the cerebrospinal fluid drainage tube from a patient who undergon thoracic endovascular aortic repair. Spinal hematoma usually develop 2 to 3 days after tube removal; however, in our patient’s case, it developed after 7 days. Therefore, a spinal subdural hematoma can occur ≤1 week after drainage tube removal, necessitating prompt magnetic resonance imaging for patients with lower limb weakness or back pain.

Background Biliary atresia (BA) is a rare disorder characterized by obstructive jaundice in infants, shortly after birth. Postoperatively, some patients exhibit portal hypertension and progressive liver fibrosis. Splenomegaly is a symptom of portal hypertension. We aimed to investigate splenomegaly as a marker for complications of portal hypertension and the relationship between splenomegaly and liver fibrosis in the long-term native liver (NL). Methods Between 1977 and 2018, 71 patients underwent hepaticojejunostomy. We included 54 patients (34 NL group, 20 liver transplant (LT) group) who fulfilled the eligibility criteria. Spleen volume (SV), total bile acids, hyaluronic acid, type IV collagen, and aspartate aminotransferase-to-platelet ratio index (APRi) were measured. Data were analyzed using Student's t-test, regression analysis, and receiver operating characteristic (ROC) curve analysis (P Results Total bile acids, hyaluronic acid, type IV collagen, and APRi increased in NL patients with a large SV at >25 years. SV and type IV collagen were correlated with NL for >25 years (r = 0.79 [P = 0.006], y = 1.1 - [0.03 × type IV collagen] [P = 0.008]). In the ROC curve analysis, the cutoff value for type IV collagen was 165 ng/mL (P = 0.07). Conclusions We suggest that SV as a prognostic index for End-Stage Liver Disease may be useful in biliary atresia. Long-term follow-up is necessary because the clinical course may be favorable in childhood but worsen during adulthood.

SUMMARY: Background: Pre-operative estimation of breast mound volume for immediate breast reconstruction is necessary for operative planning, especially in direct-to-implant reconstruction. Our purpose was to investigate the relationship between pre-operative predictions of breast mound weight from 3D imaging and actual mastectomy weight and implant size. Methods: A retrospective chart review of all patients who had previously undergone nipple-sparing mastectomy (NSM) by a single surgeon was performed. Pre-operative 3D images were reviewed and calculations of breast mound weight were performed by three independent reviewers. Intra-operative mastectomy weight and final implant weight were collected from patient charts. A regression analysis between calculated and actual values was performed. Results: There were 59 reconstructed breasts included. Pre-operative 3D imaging-guided breast weight calculations were similar across reviewers (R=0.96). Pre-operative calculations of breast weight were 49.4g (SD=134.0) smaller than actual mastectomy specimens. Mastectomy specimens were 41.0g (SD=130.2) smaller than final implant sizes. Thereby, the relationship was as follows: Pre-operative calculated breast weight < actual Mastectomy weight < implant weight. Mastectomy weight and final implant size had linear relationships with pre-operative calculations of breast weight. Formulas for predicting mastectomy weight [mastectomy weight = 63.2 + 0.95 (pre-operative calculated weight)] and implant size [Implant weight = 209.7+ 0.56 (pre-operative calculated weight)] from pre-operative calculations of breast weight were generated. Conclusions: Three-dimensional scanning technologies may be a useful tool to predict implant sizes for direct-to-implant breast reconstruction. Final implant size was heavier than intra-operative mastectomy weight and pre-operative calculated breast mound weight.

We report a Case of a mycotic abdominal aortic aneurysm caused by invasive group B streptococcus. Given the anatomical suitability with healthy segments of aortoiliac vessels, in-situ repair was performed. A cryopreserved femoral vein graft was chosen due to risks of graft reinfection and negated the need for bilateral femoral vein harvest. The patient remained clinically well and the graft patent with no concerns at 6 months follow-up. A review of literature on group B streptococcus aortitis was performed.

The duration that renal parenchyma will tolerate ischemia has continued to be debated. We have reported the cases of three patients who had undergone revascularization procedures with successful return of baseline renal function after prolonged renal artery occlusion of 14 days to 3 months. These cases highlight that aggressive revascularization can lead to successful renal salvage in selected patients. We examined the characteristics of these patients and those of others in the literature and reviewed the factors favoring recovery.

Repeated ventral hernia repair is associated with increased risk of complications and recurrence. The authors present the first study looking at how repeated ventral hernia repair affects quality of life, and whether there is a relationship between the number of prior repairs and quality-of-life improvement after surgery.A retrospective chart review was conducted of patients undergoing ventral hernia repair between August of 2017 and August of 2019, who completed at least one preoperative and postoperative Abdominal Hernia-Q. Patients were split into four cohorts based on number of prior repairs (zero, one, two, or three or more). Categorical data were compared using chi-square and Fisher's exact tests, and continuous data were analyzed using Kruskal-Wallis tests.Ninety-three patients met inclusion criteria, with 19 (20 percent), 45 (48 percent), 15 (16 percent), and 14 patients (15 percent) in each cohort, ranging from zero to three or more prior repairs. Patients with more prior repairs were significantly more likely to be readmitted and undergo reoperation (p = 0.04 and p = 0.01, respectively), in addition to significantly higher cost of care (p = 0.004). Patients with three or more prior repairs had significantly lower preoperative quality of life when compared to patients with two or fewer prior repairs (p = 0.04). However, all patients reported a similar absolute level of quality of life postoperatively, irrespective of prior repairs (p = 0.34).Treatment of recurrent hernia remains a challenge because of poor clinical outcomes and higher risk of recurrence. This study shows that patients with multiple prior ventral hernia repairs report similar postoperative quality of life as patients undergoing primary repair. This information is valuable in determining appropriate surgical candidates and improving preoperative counseling.Risk, II.

Background and Aim The aim of this study was to compare the gender-based differences in baseline characteristics, clinical presentation, and outcomes among patients who underwent percutaneous coronary intervention (PCI) in our institute. Methods This is a single-center, retrospective observational study. A total of 1,595 patients underwent PCI from a period of January 2019 to December 2019, in which 1,293 were males and 302 were females. Demographic characteristics, clinical and procedural details, and their in-hospital outcomes were all collected and analyzed. Results Females presenting with symptoms were older than males (58 vs. 60.8 years, p p p p p-0.009) and the rate of thrombolysis is low in women who presented with ST-elevation myocardial infarction (13.5 vs. 6.3%, p p-0.006). Conclusion Women who underwent PCI tend to be older and had higher rates of diabetes, hypertension, and obesity. Although mortality rates did not differ between groups, bleeding risk is higher in women.

A 60-year-old male, diabetic, nonhypertensive, tobacco chewer, presented with a history of inferior wall myocardial infarction in 2007. Patient underwent percutaneous transluminal coronary angioplasty with stent to right coronary artery in 2007, but no reports available. Now, patient was admitted with new onset crescendo angina for the last 1 month.

Objective To study the indications, technical nuances, learning curve, and outcomes associated with minimally invasive tubular discectomy of spine (MITDS) and minimally invasive tubular decompression (MITD) using the tubular retractor system and compare the outcomes with open microdiscectomy and open decompression. Materials and Methods All patients who underwent MITDS and MITD received a trial of conservative management for 6 weeks prior to surgery. Patients who had undergone open microdiscectomy and open decompression during the same period were used as controls. Operating time, intraoperative blood loss, preop and postop visual analogue scale (VAS) scores, preop and postop Oswestry disability index (ODI) scores, duration of hospital stay, complications, and need for redo surgery were analyzed. Results Thirty-two patients who underwent MITDS and 8 patients who underwent MITD were compared with an equal number of patients who underwent open microdiscectomy and open decompression, respectively. MITDS and MITD were associated with shorter hospital stay. Short-term pain outcome was better in MITDS and MITD group, although it was not statistically significant in MITD group. Functional outcome measured in terms of ODI at 6 months was not statistically significant between minimally invasive and open procedures. Conclusion Both MITDS and MITD have a significant learning curve and have a distinct advantage of shorter hospital stay. MITDS has the distinct advantage of better short-term pain relief compared with open procedures. For MITD, comparison of short-term pain relief requires a larger sample size. To establish long-term advantages of MITDS and MITD, larger sample size and long-term follow-up are needed.

Prevalence of pulmonary thromboembolism (PTE) is very high when we compare the coronavirus disease 2019 positive patients with the other patients who are admitted in intensive care unit for other different infection. Thorough evaluation of the different causative factors for PTE should be better evaluated and prevention can be tried accordingly. Incidence of subclinical PTE that can give rise to future cardiac disease needs to be studied and plan of action can be done accordingly. Newer modalities of detecting PTE using non-invasive or simple invasive techniques need to be investigated to cope up in pandemic situation. Abstract Image

Background Gliomas are a heterogeneous group of tumors where large multicenter clinical and genetic studies have become increasingly popular in their understanding. We reviewed and analyzed the findings from large databases in gliomas, seeking to understand clinically relevant information. Methods A systematic review was performed for gliomas studied using large administrative databases up to January 2020 (e.g., National Inpatient Sample [NIS], National Surgical Quality Improvement Program [NSQIP], and Surveillance, Epidemiology, and End Results Program [SEER], National Cancer Database [NCDB], and others). Results Out of 390 screened studies, 122 were analyzed. Studies included a wide range of gliomas including low- and high-grade gliomas. The SEER database (n = 83) was the most used database followed by NCDB (n = 28). The most common pathologies included glioblastoma multiforme (GBM) (n = 67), with the next category including mixes of grades II to IV glioma (n = 31). Common study themes involved evaluation of descriptive epidemiological trends, prognostic factors, comparison of different pathologies, and evaluation of outcome trends over time. Persistent health care disparities in patient outcomes were frequently seen depending on race, marital status, insurance status, hospital volume, and location, which did not change over time. Most studies showed improvement in survival because of advances in surgical and adjuvant treatments. Conclusions This study helps summarize the use of clinical administrative databases in gliomas research, informing on socioeconomic issues, surgical outcomes, and adjuvant treatments over time on a national level. Large databases allow for some study questions that would not be possible with single institution data; however, limitations remain in data curation, analysis, and reporting methods.

Background Empty nose syndrome (ENS) can be relieved by conservative therapeutic modalities such as nasal hygiene, nasal moisturizers, or nasal irrigation; however, surgery may be required for reestablishing nasal resistance and physiologic airflow. Surgical operation for ENS is often accompanied by procedural difficulties and complications. Aims To introduce and evaluate the use of nasal floor augmentation as a simple method to increase nasal resistance and ameliorate the symptoms of ENS. Materials and methods In this prospective study, the nasal floor in six patients with ENS was augmented with pieces of auricular cartilage. Subjective symptoms were examined using questionnaire assessments performed before and 3 months after surgery. Pre- and postoperative nasal resistance was evaluated using rhinomanometry. Results The nasal floor was successfully augmented in all six cases. At 3 months after surgery, the total questionnaire score reduced, and the nasal resistance increased. Conclusions and significance The findings of this study suggest that nasal floor augmentation for ENS is effective in increasing nasal resistance and reducing the nasal symptoms causally related to ENS. Informed consent statement This study was approved by the institutional Ethics Committee Review Board. All the patients provided full written and informed consent to participate in this study. The project conforms to the Code of Ethics of the World Medical Association (Declaration of Helsinki).

We want to highlight a simple technique for performing smaller craniotomies, using a marker computed tomography scan, which does not require any special equipment, training or cost and is not time-consuming. Pictorial description of two such cases have been provided.

Objectives This study aims to evaluate the subgroup consisting of uncommon pathological entities presenting with temporal lobe epilepsy (TLE). Methodology Twenty-four consecutively operated patients of lesional temporal lobe epilepsy were included in the study. Eleven cases were identified that had pathologies implicated as “uncommon” in previously done studies on the pathology of TLE. A subgroup analysis consisting of these uncommon lesions was done for clinical presentation and seizure outcome. The seizure outcome was assessed in terms of Engel and International League Against Epilepsy (ILAE) classification. Results Nine different pathological entities were identified within the study group. The mean age at surgery was 18.6 years (range 2–30 years). The mean duration of epilepsy was 48.3 months and the average duration of follow-up was 39.2months. All patients had seizures as the only complaint except three. Three patients had focal-aware seizures, two had focal motor onset, and the rest all had focal-unaware seizures. Seven patients were seizure free and the average age at diagnosis for these patients was 15.4 years (range 2–24 years.). The duration of seizure in the postoperative seizure-free group was 29.7 months and it was 81 months for the other group. All the patients with persistent postoperative seizures had focal-unaware seizures preoperatively. Conclusion Despite the small and heterogeneous nature of this subgroup of uncommon lesions causing temporal lobe epilepsy, the clinical presentation, prognostic factors, and seizure outcome are similar to the cohort of common pathologies, including mesial temporal sclerosis.

Background: The movement of the arm relative to the trunk results from 3-dimensional (3D) coordinated movements of the glenohumeral (GH) and scapulothoracic (ST) joints and dictates the scapulohumeral rhythm (SHR). Alterations in SHR increase joint overload and may lead to low functional scores, pain, and failures in patients undergoing reverse total shoulder arthroplasty (RSA). The goal of this systematic review and meta-analysis was to examine 3D SHR kinematics after RSA and compare it to that of asymptomatic shoulders. Methods: A systematic review and meta-analysis of articles in English were performed using PubMed, Embase, Cochrane Library, and SciELO. Additional studies were identified by searching bibliographies. Search terms included “Reverse shoulder arthroplasty”, “3D”, and “scapula”. It was selected cross-sectional studies that reported SHR with 3D motion analysis systems in patients who underwent RSA and asymptomatic controls. Two authors independently performed the extraction of articles using predefined data fields, including study quality indicators. Results: Data from four studies were included in quantitative analysis, totaling 48 shoulders with RSA and 63 asymptomatic shoulders. Pooled analyses were based on random-effects model (DerSimonian-Laird). A statistically smaller SHR ratio was observed in the RSA group than that in the control group (P < .00001), meaning a greater contribution of ST joint in relation to GH joint for arm elevation. The standardized mean difference was −1.16 (95% confidence interval: −1.64, −0.67). A sensitivity analysis with three more studies that had imputed data on control group did not change the direction of the effect. The standardized mean difference on sensitivity analysis was −0.60 (P = .03; 95% confidence interval: −1.13, −0.06). It was detected as “not important heterogeneity” within the comparison (I2: 22%). Chi-square was not statistically significant (Chi2: 3.85), and I2 was 22%. Tau2 was not zero (Tau2: 0.05). Sensitivity analysis showed an I2 of 74%, which might represent substantial heterogeneity, Chi-square was not statistically significant (Chi2: 23.01), and Tau2 was not zero (Tau2: 0.37). Conclusion: This study found that RSA shoulders have an increased contribution of ST joint during arm elevation, compared with asymptomatic shoulders. More movement in ST joint in proportion to GH joint increases GH joint contact forces, which could lead to component loosening or other complications. Further studies should address the clinical implications of this kinematic finding.

Introduction COVID-19 has affected plastic surgeons like never before. We conducted an all-India survey to find how the practice was affected among public/private sector, reconstructive/aesthetic practice, and consultants/residents. We have proposed some solutions to the identified problems, which are supported by previous literature. Methods A survey framed in Google forms was circulated through WhatsApp and emails in August 2020. Closed and semiopen questions regarding changes in personal and professional lives, coping strategies adopted, and open questions for suggestions in improving practice, academics and measures to tackle the pandemic were included. Responses were collected in an Excel sheet and analysis done using SPSS software. Results A total of 220 consented responses were obtained. Public hospital practitioners had to bear the COVID-related administrative as well as executive works, especially residents, which led to anxiety, family concern, burnout, and concern about the loss of skills and academics. Patient interaction was also reduced. Aesthetic surgeons bore more financial loss. Conclusions Plastic surgeons in India faced decrease in caseload, financial loss, COVID-related duties, workload for residents, reduced academics, family and mental health problems, difficulty with personal protection equipment (PPE) during surgeries, and queries from patients. These can be solved by doing cases within the limits of protocols and safety, pooling public and private sector for COVID duties, rotating residents' groups to reduce workload, using telemedicine for academics and patient consultations, and providing social support groups to surgeons.

We present a rare case of reconstruction surgery of Ideberg type V intra-articular scapular fracture nonunion postoperatively. Sufficient osteotomy for the mobilization of displaced fragments and good visualization of the glenoid fossa by infraspinatus tenotomy, capsular incision, and partial detachment of the glenoid posterior labrum through the Judet approach contributed to a good anatomical reduction of the glenoid fossa and favorable clinical outcomes. We describe a detailed surgical technique, management and clinical outcomes after a 1-year follow-up, with a review of the literature.

Oxidized regenerated cellulose (ORC) is an absorbable hemostat commonly used during gynecologic surgery. We present a case in which ORC was used in a patient undergoing posterior pelvic exenteration with ureteroneocystostomy for excision of a malignant pelvic mass. At the conclusion of these procedures, the laparotomy pad count was reported as incomplete likely due to the large number of laparotomy pads used and changes in nursing staff. Abdominal radiographs were obtained to verify no pads were retained in the abdominal cavity. These identified a poorly defined radiolucency deep in the patient’s pelvis, requiring the surgical incision be reopened. Upon reexploration, no evidence of a retained surgical sponge could be identified. However, ORC was identified at the site of the radiolucency in question. Radiographs of this material, once removed, confirmed its radiolucent appearance. This experience clearly demonstrates that oxidized regenerated cellulose can mimic a retained surgical sponge on intraoperative radiographs. Dissemination of this knowledge will hopefully help to avoid radiographic misidentification of ORC in the perioperative window and minimizing the risk of unnecessary surgical interventions in the future.

Langerhans cell histiocytosis (LCH) is a proliferative disease of histiocytic cells that rarely affects adults. Different therapeutic options have been used in the treatment of this condition depending on the severity of the disease. However, the management of LCH is often controversial when a resection with clean margins is not achieved. We present a 37-year-old male who was diagnosed with LCH affecting the middle third of the clavicle. The patient was subjected to a wide resection of the lesion creating a large bone defect. The reconstruction was then performed using a 3-D printed porous pseudo-prosthesis (Ti6AL4V) which was fixed using an anatomical clavicular plate (Depuy-Synthes, Raynham, MA, USA) and locking screws. The implant trabeculae were filled with bioactive bone graft substitute (GlassBONETM, Noraker, France). After two years of follow-up the patient was pain free, had a full range of movement, and scored 100 on the Constant Scale and 2.5 points on the disabilities of the arm, shoulder and hand score (DASH). Moreover, in this case, the implantation of the 3-D printed pseudo-prosthesis avoided the use of adjuvant therapies such as radiotherapy. The use of a 3-D printed pseudo-prosthesis achieved an excellent clinical and functional outcome in the treatment of a large bone defect, following a resection of a LCH of the clavicle. 3-D printed pseudo-prostheses could be useful instruments for the treatment of bone defects following large bone resections in musculoskeletal tumors.

Bony stabilization procedures are a reliable solution for recurrent shoulder instability, but have a steep learning curve due to technical difficulties. Meticulous capsular closure is critical, and can be augmented with suture anchor constructs. Additionally, while fracture or fragmentation of the coracoid graft is a relatively uncommon, it is devastating. Here, we describe the use of additional circumferential suture fixation to Improve compression across the graft/glenoid interface, and help mitigate the risk of fracture bony augmentation procedures

A displaced surgical neck fracture can be a good indication for antegrade intramedullary nailing. However, nail insertion may result in malreduction and translational displacement of the humeral head fragment because of muscle traction and size discrepancies between the diameters of the medullary canal and the intramedullary nail. We used blocking screw augmentation in 20 fractures with residual medial displacement of the distal fragment after nail insertion to anatomically reduce displacement of the fracture and to maintain the reduced position before bone union. A blocking screw was placed percutaneously at the lateral side of the canal. Next, a straight intramedullary nail was reinserted medial to the blocking screw. Finally, the nail was locked both proximally and distally. All cases showed bone union without fixation failure at the time of the final follow-up. Blocking screw augmentation with intramedullary nailing is feasible for the treatment of humeral surgical neck fractures and is thought to be helpful for fracture reduction during surgery and stable fixation after surgery.

Background Monthly incidence of elbow ulnar collateral ligament (UCL) injuries and surgeries is relatively unknown. Defining seasonal peaks of UCL injuries and surgeries may identify opportunities for injury-prevention strategies. The purpose of this study is to analyze seasonal and monthly variations in UCL injuries and surgeries across the United States with emphasis on the timing of baseball season. Methods The Truven Health MarketScan database (2013-2015) was queried for patients younger than 40 years with a diagnosis code of elbow UCL sprain and a procedural code for UCL repair or reconstruction. Differences in patient characteristics were evaluated using chi-square and Mann-Whitney U-tests. Negative binomial regression models were calculated for UCL injuries and surgeries to assess monthly trends. Results UCL injuries were sustained by 13,894 patients, with 1404 (10.1%) patients having undergone surgery. The median age at first diagnosis was 17 years, and the median age of patients requiring surgery decreased from 20 to 18 years from 2013 to 2015 (P = .75). Most UCL injuries (n = 3785) and surgeries (n = 438) occurred during the spring season (March 21-June 20), and spring injuries were most likely to result in surgical management (11.6%). During the baseball season (March to September), the number of UCL injuries peaked in April/May, then declined, except for a second peak in September/October (incidence rate ratio 0.97; confidence interval 0.95, 0.99; P = .01). The number of UCL surgeries steadily increased from March (n = 116) to June (n = 152), followed by a gradual decline (incidence rate ratio 1.00; confidence interval 0.96, 1.04; P = .99). Conclusion Athletes frequently experienced UCL injuries and surgeries in the early months (April-June) of the baseball season. More emphasis should be paid to rehabilitative strategies at the beginning of a baseball season to help mitigate injury risk.

Summary: To compare the clinical efficacy and safety of Thulium laser enucleation of prostate (ThuLEP) and Holmium laser enucleation of prostate (HoLEP). We systematically searched PubMed, Embase, and Cochrane Library databases within a period from the date of database establishment to October 2020. RevMan 5.4. was used for calculation and statistical analyses. 8 studies of 2125 patients were included. ThuLEP provided less hemoglobin decrease (MD: −0.37, 95%CI -0.61 to −0.14, P = 0.002) and shorter length of hospital stay (MD: −0.41, 95%CI -0.72 to −0.10, P = 0.01). During the postoperative follow-ups, statistically significant differences only were found in IPSS (MD: −0.96; 95%CI -1.27 to −0.65; P

Aim: There lacks a predictive model for overall survival (OS) of node-negative perihilar cholangiocarcinoma (PHC). This study aimed at developing and validating a prognostic nomogram to predict OS of node-negative PHC after resection. Methods: We established a nomogram via multivariate regression analysis by using the design cohort (n = 410, obtained from Surveillance, Epidemiology, and End Results database), and its external verification was done in the validation cohort (n = 100, the First Affiliated Hospital of Sun Yat-sen University). Predictive accuracy of the nomogram was assessed by concordance-index (C-index), calibration curves, and decision curve analysis (DCA). Performance of the nomogram was compared with the American Joint Committee on Cancer (AJCC) staging system. Results: Multivariate regression analysis revealed that age, tumor grade, and the count of examined lymph nodes were independent prognostic factors for OS of node-negative PHC. The nomogram had a C-index of 0.603 and 0.626 in design cohort and validation cohort, respectively, which was better than that of AJCC staging system (both p

Summary Introduction To analyze the clinicopathological characteristics, immunohistochemistry, genotyping and prognosis of patients in the multicenter GIST data in Inner Mongolia, China. Methods Retrospective analysis was performed on GIST data from January 2013 to January 2018 in Inner Mongolia. Descriptive statistics were used to analyze the clinical characteristics of GIST patients. The Chi-square test was performed on the modified NIH criteria by age distribution, and Kaplan-Merie method was used for survival analysis. Results A total of 804 patients were included in the GIST database in Inner Mongolia, with a male to female ratio of 1.1102:1. The most common location was the gastric (465). Mitotic count ≤5/50HPFs was found in 67.3 % patients. There were 276 patients with tumor diameter of 2–5 cm and 354 patients with tumor diameter of 5.1–10 cm.The modified NIH criteria was mainly of intermediate risk (210) and high risk (342). The recurrence and metastasis of patients were related to the tumor location, mitotic index, tumor size, and modified NIH criteria. All patients were followed up for 1–10 years, in which 63.1 % of them were followed up for at least three years. The 3-year survival rates of patients with modified NIH criteria of very low risk, low risk, intermediate risk, and high risk were 100 %, 100 %, 100 %, and 96.3 %, respectively. Conclusions The incidence of GIST in middle-aged and elder people in Inner Mongolia is high, and the long-term prognosis of patients after surgical treatment is good, which can objectively reflect the incidence, diagnosis and treatment of GIST in Inner Mongolia.

Background Distal humerus fractures (DHF) pose a treatment challenge in elderly patients. We sought to systematically review and report the clinical outcomes of the nonoperative approach (e.g., “bag of bones”) for the treatment of these injuries, and the rate of conversion to delayed surgery. Methods A comprehensive review of the literature using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines was conducted. Studies involving outcomes following nonoperative treatment of DHF in patients >65 years of age were included from 1985 to present. Data regarding patient age, DHF type, nonoperative treatment method, complications, conversion to delayed surgery, range of motion, union rate, and surgeon and patient reported outcome measures were extracted. Results A total of five studies met inclusion criteria (all level IV evidence), yielding a total of 143 patients (mean age: 73.5 years to 87.4 years) with 7.1 months to 55 months of follow-up. The mean Mayo Elbow Performance Index (MEPI) scores were good to excellent across several studies (range 83 - 93.1). Multiple studies reported good range of motion (mean arc of motion: 81 to 106 degrees) and low levels of upper extremity disability (mean Quick Disability of the Arm-Shoulder-Hand (Q-DASH) scores: 31.3 to 38.5) at final follow-up. The rate of conversion to total elbow arthroplasty and operative fixation ranged from 0% to 7.5% and 0% to 5%, respectively. Conclusion Nonoperative management of distal humerus fractures in the elderly seems to be associated with acceptable functional outcomes and low rates of delayed surgery. This information is important for patient counseling and treatment decision-making.

Background: Cerclage fixation is a known orthopedic technique shown to be beneficial for circumferential augmentation when screw fixation cannot be used or is undesirable. However, ongoing advances in suture materials and knot techniques exist, and there is a paucity of evidence existing which evaluates comparisons between the two. The objective of this study was to investigate the strength and durability of cerclage fixation between the Nice knot suture technique and monofilament wire. Methods: Static displacement over time and compression load testing were analyzed. Compression testing was conducted with the Jamar Hydraulic Hand Dynamometer. Distraction testing was conducted using the Instron test system with its associated program. The Nice knot was tied using number 2 and number 5 FiberWire (Arthrex) and compared to monofilament wire. Clinical failure (displacement of 10 mm), absolute failure (opening of the knot or material failure), maximum compression achieved, and steady state compression maintained were the outcomes of interest. Results: Double-stranded monofilament wire produces maximum consistent compression of 90 kg, followed by single-stranded monofilament wire (60 kg). Number 5 FiberWire has a higher maximum compression load than number 2 FiberWire (50 kg vs. 22 kg), but it is lower than that of the double-stranded monofilament wire constructs. When compared to the single-stranded monofilament construct, the number 5 FiberWire Nice knot is comparable (P < .05). Average steady state compression achieved after 10 minutes of resting showed double-stranded monofilament wire to be 65 kg compared to single- stranded monofilament wire at 42 kg, which when, compared to suture, number 5 FiberWire measured at 15 kg and number 2 FiberWire at 8 kg. Average tension results from Instron distraction testing showed the double-stranded monofilament wire construct was able to withstand greater forces up to a displacement of 6 mm, after which the number 5 FiberWire Nice knot was stiffer. Number 5 FiberWire shows the most linear tension relationship, revealing it more efficiently withstands elastic forces. Load to failure was higher in the number 5 FiberWire Nice knot construct than that in both the monofilament wire constructs. The modes of failure for the Nice knot were always at the knot suture interface rather than at the knot. Conclusion: We propose this suture technique to be a viable alternative method for cerclaging to fix upper limb long-bone fractures.

Context Tumors of the jugular foramen present a challenge to skull base surgeons. Their rarity, coupled with the complex anatomy of the region require exquisite knowledge and surgical technique. We present the history of the craniocervical approach to the jugular foramen, as well as surgical advice on how to manage the different extensions these tumors may present. The surgical nuances come from the experience of our skull base team managing over 150 tumors of the jugular foramen over the past 30 years. The history of the craniocervical approach was obtained by reviewing articles on surgery of the jugular foramen published on PUBMED over the past 100 years. History The first craniocervical approach may be attributed to Gardner et al. in 1891, with posterior contributions from Shapiro and Neues, Gejrot, Kempe et al, Hilding and Greenberg, and Glasscock. Nuances Cervical dissection with identification of the jugular vein, carotid bifurcation, and IX to XII cranial nerves was performed. Mastoidectomy with exposition of the fallopian canal, labyrinth, middle ear, sigmoid sinus, followed by a trans-sigmoid craniotomy with transposition of the vertebral artery gave access to the temporal and intracranial region. Conclusion Approaching the jugular foramen is the epitome of skull base surgery. Several modifications of the standard approach may be necessary depending on the extension of the tumor.

Introduction: There is a growing momentum for the collaboration between multiple disciplines for the prevention and treatment of skeletal-related events (SREs) in patients with metastatic spinal tumors. However, the effectiveness of multidisciplinary approaches remains unclear. Hence, we conducted an exploratory study to examine the impact of liaison treatment for metastatic spinal tumor (LMST) on the prevention of SREs among patients with a metastatic spinal tumor. Methods: This study was an exploratory interrupted time series conducted in a single medical center. Overall, 1,043 patients with a metastatic spinal tumor diagnosed between January 2011 and December 2020 were included. The LMST was implemented in January 2014. The LMST team consisted of the orthopedic surgery, thoracic surgery, breast and thyroid surgery, clinical oncology, urology, and radiology departments. Monthly joint conferences were held for patients with spinal instability, and the incidence of SRE was measured at 6-month intervals. Results: Throughout the study period, we identified 66 SRE incidences. After the implementation of the LMST, a level change of −5.2% (95% confidence interval [CI]: −11.7 to 1.3, p = 0.11) was observed. Subsequently, a post-implementation trend change of −0.3% (95% CI: −2.0 to 1.5, p = 0.75) beyond the baseline was noted. Conclusions: We suggest both immediate and gradual effects of the introduction of the LMST on deterring the development of SREs. Our results support the global trend of introducing a multidisciplinary approach for the treatment of metastatic spinal tumors.

Introduction: Due to the narrow portal of entry, microendoscopic laminectomy (MEL) is associated with a risk of postoperative spinal epidural hematoma (POSEH). This risk might be higher when performing multiple-level (m-) MEL. The purpose of this study is to clarify the incidence rate of POSEH following single-level (s-) and m-MEL by each interlaminar level and identify the risk factors for POSEH following m-MEL. Methods: A total of 379 patients underwent MEL of the lumbar spine (s-MEL, n=141; m-MEL, n=238). We determined the incidence of POSEH following s-MEL and m-MEL by each interlaminar level. For m-MEL, we clarified the correlation between POSEH and possible risk factors, such as operative findings, the sequence of operated interlaminar levels, and the preoperative cross-sectional dural area (CSA) on magnetic resonance imaging. Results: The incidence rate at L2/3 was significantly higher than that at L3/4 and L4/5. Patients who underwent L2/3 decompression at the end of the procedure showed a higher incidence of POSEH at the L2/3 level. Preoperative spinal stenosis was associated with POSEH at the L2/3 level, and CSA of 56 mm2 was a predictive factor for POSEH. Logistic regression analysis revealed that both were significant risk factors. Conclusions: In patients undergoing m-MEL, the incidence of POSEH is highest at the L2/3 level, and treatment of the L2/3 level at the end of the procedure and the presence of spinal stenosis are risk factors for POSEH.

Introduction: The loco-check is a simple tool for evaluating locomotive syndrome (LS), and a previous report suggested that it can be used to identify patients with stage 2 LS. The purpose of this study was to investigate the improvement in LS stage after surgery based on the loco-check in elderly patients with lumbar spinal stenosis (LSS) and to clarify the characteristics associated with improvement to non-stage 2 LS. Methods: We reviewed 40 elderly patients with LSS who underwent surgery at our institution. We compared the pre- and postoperative Japanese Orthopaedic Association score, loco-check, Oswestry Disability Index, EuroQoL-5 dimension utility values, and the EuroQoL-visual analog scale. We divided patients according to the presence or absence of stage 2 LS after surgery and compared their preoperative clinical findings and assessment measures. Results: Ninety percent of all patients had been preoperatively diagnosed with stage 2 LS according to the loco-check. After surgery, patients showed a decreased number of affirmative answers on the loco-check, according to which only 65% were postoperatively diagnosed with stage 2 LS. The receiver operating characteristic curve analysis identified less than four affirmative answers on the loco-check before LSS as predictive of improvement to non-stage 2 LS. Conclusions: Surgical treatment for elderly patients with LSS could improve LS. In patients with less than four affirmative answers on the loco-check preoperatively, improvement to non-stage 2 LS status may be possible.

Introduction: Assessments of early postoperative bony union after posterior lumbar interbody fusion via computed tomography (CT) have revealed cases in which interbody fixation by bony union resulted in nonfusion due to bone absorption. The apparent bone union state reverted to a nonunion state several months later, exhibiting a so-called “fake union” phenomenon. Additionally, few reports have evaluated the effect of teriparatide on bony union. The present study aimed to evaluate the frequency of change in assessment from fusion to nonfusion in the postoperative follow-up of lumbar interbody fusion, compare the late postoperative bony union rates in groups with or without early postoperative fusion, and examine the effect of postoperative teriparatide in those groups. Methods: Sixty-nine subjects enrolled from multiple hospitals were prospectively evaluated following single-level lumbar interbody fusion. The patients were randomly allocated into treatment with or without weekly postoperative teriparatide. The subjects were then classified as having bony union or nonfusion at 2 months postoperatively, and fusion rates at 6 months were compared. For the evaluation of bony union, blinded radiological examinations were performed via CT. Additional comparisons were made according to teriparatide use. Results: The rate of nonunion at 6 months postoperatively in patients with fusion at 2 months postoperatively was 27.8%. Among subjects with bony union at 2 months postoperatively, the fusion rate at 6 months in those who received teriparatide was 93.3% (p=0.027) versus 57.1% in those who did not. Conclusions: The rate of nonunion at 6 months postoperatively in patients exhibiting union at 2 months after surgery was 27.8%. Postoperative weekly teriparatide treatment significantly reduced the rate of fake union.

Introduction: Sacroiliac joint (SIJ) arthrodesis using a minimally invasive technique, particularly the triangular implant system, is performed in patients with SIJ dysfunction in the United States and Europe. We report three-year clinical outcomes of the first minimally invasive SIJ arthrodesis procedures using the implants performed in Japan. Methods: Five patients (one man and four women; age: 56.4±16.9 years) with SIJ pain who underwent SIJ arthrodesis using a triangular implant system in 2017 were included. In addition to operation time and blood loss, pain intensity (visual analog scale [VAS]) and functional impairment (Oswestry disability index [ODI]) were assessed preoperatively and at a 36-month follow-up. Implant loosening and osseous bridging across the joint were evaluated using computed tomography images, and patients' satisfaction with the surgery was also assessed at 12 and 36 months. Results: The surgical time was 67.7±13.1 minutes, and blood loss was 7.4±6.9 mL. The mean VAS value improved significantly from 88.0±8.4 mm to 33.6±31.9 mm at 3 months and was maintained at 46.4±30.9 mm at 36 months (P
