Objectives: Ebstein’s anomaly is a congenital defect characterized by a lack of delamination and apical displacement of the tricuspid valve, tricuspid insufficiency, right atrial enlargement, and ventricular dysfunction. To analyze the results and evolution of the different surgical strategies, data were collected from 45 patients operated on during 1990-2018. Twenty-six patients were included with a median age at initial surgery of 11.3 years (range: 13 days-18.6 years). Method: Procedures were plastic 10 patients (38%), cone technique reconstruction 11 (42%), and replacement 5 (19%). Additional interventions were required in 7 patients: cavo-pulmonary anastomosis 4 and Cox-maze 4. Nine patients (34.6%) required reoperation due to severe tricuspid insufficiency. Six had previous plastic, two bioprothesis, and one, cone. Results: Overall mortality was 11.5% (3) at a median of 10.1 years post-surgery (range: 5.7-10.12) associated with arrhythmias (p = 0.05), right (p = 0.008), left (p = 0.0001) ventricular dysfunction and reoperations (p = 0.03). None were previous conus. Median follow-up was 6.5 years (range: 1-29.1). Ninety-one-point-six percent were in functional class I/II and 79.2% in sinus rhythm. Conclusions: The results of the different classic techniques were similar, although not free of complications and reoperations. Cone reconstruction proved to be effective, with low surgical mortality, less need for reoperations, and durability in the medium term. [ABSTRACT FROM AUTHOR]

Objective: in recent years, bariatric surgery has gained popularity as a treatment for obesity worldwide. While patients do experience weight loss after surgery, it is important to be aware that serious nutritional deficiencies may also occur. This study was conducted to evaluate the nutritional status of morbidly obese patients in the first six months after sleeve gastrectomy. Methods: the study was planned as a retrospective study. The data of 76 patients aged 19-64 years who had undergone bariatric surgery and were followed by a dietitian for at least 6 months were included in the study. Preoperative and postoperative biochemical parameters and anthropometric measurements of the patients were taken. Results: the lowest body weight of the patients was found at postoperative month 6 (81.74 ± 14.83 kg), the body weight at the preoperative period (115.86 ± 21.28 kg) and postoperative month 1 (100.39 ± 18.28 kg), and the body weight at postoperative month 1 was statistically lower than at the preoperative period. The preoperative body weights and BMI values of the patients were higher than at postoperative months 1 and 6, and the postoperative month 1 values were higher than at postoperative month 6 (p < 0.05). The lowest fasting blood glucose (83.48 ± 8.44 mg/dL), HbA1c (4.96 ± 0.95 %), and Homa-IR (3.34 ± 0.92) were observed at the postoperative month 6. Compared with the preoperative period, the iron level of the patients increased from 69.54 ± 29.82 µg/dL to 96.52 ± 25.39 µg/dL in postoperative month 6, vitamin D levels from 14.48 ± 8.70 µg/dL to 23.96 ± 4.79 µg/dL. While preoperative blood triglyceride and LDL values were statistically higher than in postoperative months 1 and 6, the HDL value was lower (p < 0.05). [ABSTRACT FROM AUTHOR]

The German Conrad Johann Martin Langenbeck made important contributions to anatomical and surgical knowledge during the late 18th and early 19th centuries. However, His work and legacy is little known and difficult to access, both in Europe and in America. Literature review of the databases PubMed, LILACS, Cochrane Library; "Google" and university libraries. The following keywords have been used: "anatomy and surgery". In this analysis a critical analysis of the known literature about this historical figure is carried out. His multiple contributions to the study of human morphology, his surgical interventions, his legacy at the University of Göttingen and the German model of surgery are noted. Langenbeck was a prominent anatomist, surgeon, professor and researcher, before the discovery of anesthesia changed everything, a time when cadaver dissection was essential to the design of successful operations. The name of CJM Langenbeck will always endure through his work, anatomical terms and operations, and he should be remembered as the last anatomist surgeon of the 19th century. [ABSTRACT FROM AUTHOR]

Osteosynthesis is a surgical technique performed in bone fractures for the reduction of bone fragments and their stabilization in a suitable position, allowing the patient to recover their motor activity. This report deals with the case of a giant anteater in the municipality of Yopal, Colombia, which was admitted to the veterinary service due to a thoracic limb injury caused by a car accident. The treatment performed was surgical, after a fracture of the radio-ulnar diaphysis was diagnosed. Resolution was carried out through osteosynthesis of both bone structures with a double locking titanium plate system under an anesthetic plan of 4 mg/Kg ketamine, 0.025 mg/kg dexmedetomidine and 0.1 mg/Kg midazolam. Maintenance was performed with isoflurane at a rate of 3% at the beginning of anesthesia and 1.5% as maintenance. The reduction of the fracture using the aforementioned technique resulted in its effective stabilization. The real and growing problem of bone fractures affects different wild fauna that move in search of food, water or shelter, directly threatening biodiversity. [ABSTRACT FROM AUTHOR]

Introduction: 310 million major surgeries are performed annually and 1 to 4% will have life-threatening complications, with bleeding being one of the main complications; because of this, strategies are sought to reduce post-surgical mortality from this cause, such as the use of desmopressin 30 minutes before surgery. However, this measure is still rarely used. Material and methods: systematized search in PubMed with key words desmopressin, bleeding, surgery, decreased bleeding, limited to humans, review and experimental articles; obtaining 115 results, selecting 21 and adding two independent search articles on surgery and hemorrhage statistics worldwide. Results: desmopressin used presurgery has been shown to reduce bleeding in cardiac, oncological, otolaryngology, and renal biopsy surgery. Conclusion: desmopressin administered at doses of 0.3-0.5 μg/kg intravenously 30 minutes prior to the start of surgery or renal biopsy has been shown to reduce bleeding without serious adverse effects.

Presentamos el primer caso clínico en nuestro paísde un paciente con estenosis del canal anal, su forma de presentación, tratamiento quirúrgico y evolución.

Arthrofibrosis is a challenging complication associated with knee injuries in both children and adults. While much is known about managing arthrofibrosis in adults, it is necessary to understand its unique aspects and management strategies in the pediatric population. This paper provides an overview of arthrofibrosis in pediatric orthopedic surgery, focusing on its causes, implications, classifications, and management. This paper is a comprehensive review of the literature and existing research on arthrofibrosis in pediatric patients. Arthrofibrosis is characterized by excessive collagen production and adhesions, leading to restricted joint motion and pain. It is associated with an immune response and fibrosis within and around the joint. Arthrofibrosis can result from various knee injuries in pediatric patients, including tibial spine fractures, ACL and PCL injuries, and extra-articular procedures. Technical factors at the time of surgery play a role in the development of motion loss and should be addressed to minimize complications. Preventing arthrofibrosis through early physical therapy is recommended. Non-operative management, including dynamic splinting and serial casting, has shown some benefits. New pharmacologic approaches to lysis of adhesions have shown promise. Surgical interventions, consisting of arthroscopic lysis of adhesions (LOA) and manipulation under anesthesia (MUA), can significantly improve motion and functional outcomes. Arthrofibrosis poses unique challenges in pediatric patients, demanding a nuanced approach that includes prevention, early intervention with non-operative means, and improvements in surgical techniques. Modern pharmacological interventions offer promise for the future. Customized interventions and research focused on pediatric patients are critical for optimal outcomes. [ABSTRACT FROM AUTHOR]

The trauma of surgery induces systemic stress that alters homeostasis and develops postoperative complications, particularly in high-risk patients. Surgical stress is produced by an acute inflammatory process and by the imbalance between the levels of pro-oxidant molecules and the activity of antioxidant systems. This imbalance is known as oxidative stress (OS). These two mechanisms underlie perioperative complications are reduced with anaesthetic management since some anaesthetics have antioxidant capacity. OS could negatively impact all forms of major surgery, particularly in elderly patients and patients with comorbidities. This review aims to present the concept and cellular bases of OS and its relationship with the most common complications in the perioperative period of cardiac and noncardiac surgery, as well as the quantitative determination of the level of OS through serum biomarkers. Furthermore, the effect of anaesthetics on OS and the use of antioxidant therapies in preventing postoperative complications induced by OS are reviewed. [ABSTRACT FROM AUTHOR]

Objective: It is imperative to create a teamwork that generates a two-way interaction radiologist-surgeon that allows the accurate diagnosis of external abdominal wall hernias. Method: The clinical records of the patients shown as illustrative examples with a diagnosis of abdominal wall hernia were analyzed. Standardization in the interpretation of the studies is proposed, establishing a structured radiological report that contains and describes in detail 10 points. Results: The clinical information sent in the study requests did not have complete information and the surgical history was not indicated, considered essential especially in the event of mesh placement and/or associated complications. Both ultrasound and computed tomography are objective study methods. Conclusion: Referral to a surgeon for a targeted clinical evaluation, emphasizing the importance of performing a thorough and targeted examination of the patient, regardless of the reason for consultation, prior to imaging facilitates accurate diagnosis and reduces the cost of care. External hernias of the abdominal wall represent a frequent pathology, so the specific radiological report in this regard will allow the generation of a learning curve. [ABSTRACT FROM AUTHOR]

El Adenoma Hepatocelular (AH) es un tumor hepático benigno, su diagnóstico ha avanzado gracias a los avances en los métodos moleculares, facilitaron dividirlos en subtipos, con diferentes pronósticos e indicaciones terapéuticas. Se presenta el caso clínico de una paciente, de 40 años con hallazgo ecográfico de tumor hepático, la Tomografía de Abdomen y Pelvis voluminosa lesión sólida heterogénea, en la Resonancia Magnética compatible con Adenoma esteatósico (asociado a mutación HNF1 alfa). Se decide tratamiento quirúrgico, con resección de los segmentos 6 y 7. La Anatomía patológica concluye: Compatible con el subtipo inflamatorio. Los Adenoma hepáticos (AH) son tumores raros, solitarios de estirpe epitelial, benignos. Se presentan en mujeres de edad fértil y asociado al consumo de anticonceptivos orales y estrógenos. Estos tumores predominan en hígado derecho, con proliferación de células parecidas a los hepatocitos normales, pero desorganizados y sin arquitectura lobular normal, sin ductos biliares ni tejido conectivo de sostén. Los AH así como el resto de los tumores hepáticos benignos, han aumentado su incidencia de la mano con el avance de la imagenología abdominal. La importancia de la diferenciación con el resto de los tumores hepáticos benignos surge del potencial maligno de éstos. Podemos clasificar a los pacientes según el perfil molecular asociado a marcadores inmunohistoquímicos. Los estudios de imagen son fundamentales para la diferenciación tumoral en diagnóstico y planear la terapéutica. El tratamiento será individualizado, determinada por la clínica, la variedad de subtipos, y la evolución. Debido a la complejidad de la enfermedad, el tratamiento de la HA es uno de los mejores ejemplos de abordaje individualizado en unidades hepatobiliares.

The treatment of obesity is complex, and in some cases lifestyle changes are not enough to improve comorbidities in some pediatric patients, so we can rely on the use of drugs to improve them and avoid progression of these alterations. Currently, only 3 drugs are approved for the treatment of obesity in the pediatric population: metformin, orlistat and liraglutide. It is suggested that pharmacological treatment be reserved for patients with associated comorbidities who have not responded to a structured weight reduction program. With respect to surgical treatment, this has been reserved for those patients who have failed pharmacological treatment and present serious obesity-related complications. Finally, it is important that the patient and parents or guardians understand the limitations, adverse effects of drugs and the risks of surgical management, insisting that the mainstay of obesity management is lifestyle change.

Introduction: our aim was to evaluate the clinical outcomes and complications of anterior tibialis tendon transfer (ATTT) in children with dynamic supination after clubfoot treatment. Material and methods: children with dynamic supination after initial treatment with Ponseti method or surgery who underwent ATTT between 2008 and 2020 were included for evaluation. Demographic data, previous treatment, associated procedures and fixation method were analyzed. Functional results were evaluated with the grading system described by Thompson. Complications and their treatment were analyzed. Results: a total of 39 patients (57 feet) were analyzed. 70% received previous treatment with Ponseti method, 19.3% underwent surgical posteromedial release, and 10.7% another type of surgical treatment. 88% of cases required associated procedures including Achilles tendon lengthening or tenotomy, plantar fasciotomy, tibial osteotomy, lateral column shortening, posterior release. The predominant type of fixation was the pull-out button method (96.5%). The average follow-up was 31.5 months. According to the Thompson grading system, 52 patients presented good results, two fair and three poor. 98.2% of the feet showed active contraction of the transferred tibialis anterior tendon. There were four complications: plantar irritation, synovial cyst in the dorsum of the foot and deep infection. Two feet required unplanned surgery. Conclusion: anterior tibialis tendon transfer is an effective technique to correct residual dynamic supination in patients with clubfoot. [ABSTRACT FROM AUTHOR]

Introduction: Hemorrhoidectomy produces intense postoperative pain, recommending multimodal analgesia for its management, remaining as an unresolved problem. The aim of this study was to evaluate the analgesic effectiveness of three pharmacological combinations for post-hemorrhoidectomy pain. Material and Method: A prospective, randomized clinical study, conducted at the INDISA Clinic, between December 2019 and December 2021, including patients with an indication for elective hemorrhoidectomy. Hemorrhoidectomies associated with another surgical procedure, pregnant/lactating women, adverse drug reactions (ADRs) to the study drugs, liver and kidney diseases, or mental disorders/disabilities were excluded. Group I (control): Ketorolac, Tramadol, Paracetamol. Group II: Group I and Nifedipine 0.2% topical. Group III: Buprenorphine patch 10 mcg/hour, Paracetamol and Ketorolac. Associated with a diet rich in fiber, polyethylene glycol, sitz baths, and omeprazole. Descriptive and analytical statistics were used using Chi-square, ANOVA-Bonferroni, Kruskal Wallis, Wilcoxon and Fisher test. Software R, using an alpha of 5%. Of 117 patients, 39 = Group I, 41 = Group II and 37 = Group III were enrolled. Results: There were no differences in analgesic effectiveness (p = 0.45). For the ADRs, it was observed that the patients with Buprenorphine had more nausea (p = 0.08), vomiting (p = 0.04), dermatitis (p < 0.001) and itching (p = 0.006). Discussion and Conclusion: There were no significant differences for post-hemorrhoidectomy analgesic effectiveness when comparing the study groups. The use of topical nifedipine is recommended as a complement to multimodal therapy as it improves results without increasing adverse drugs reaction (ADR).The use of buprenorphine presented more ADR without better results as an analgesic.The main determinant for pain relief was the time elapsed since surgery.

Background: Necrotizing enterocolitis (NEC) is the most common surgical disease in the neonatal period with a high mortality rate. To date, there is no consensus on the indications for surgery in the absence of pneumoperitoneum. This study aimed to determine the indications for surgery in pre-term infants with NEC and their mortality. Methods: We conducted a descriptive, observational, cross-sectional, and retrospective study including pre-term infants with NEC from two perinatal hospitals in Toluca, Mexico, between 2017 and 2022. Descriptive and inferential statistics and group comparisons were performed using Fisher and Kruskal-Wallis tests. Results: Of 236 patients with NEC, 52 (22%) required surgery; we analyzed 42 cases with complete clinical records. The indications for surgery were divided into (a) clinical deterioration (33.3%); (b) radiographic findings (31%); (c) laboratory alterations (19%); and (d) positive paracentesis (16.7%). The group of radiographic findings underwent surgery later, up to 2 days after the other groups. The mortality rate of surgical NEC was 42.9%. Conclusions: The most common indication for surgery in pre-term infants with NEC was clinical worsening despite optimal medical management; radiographic findings were the indication associated with the highest mortality. Laboratory abnormalities and positive paracentesis were the indications with the best outcomes but the least used. [ABSTRACT FROM AUTHOR]

Morton's neuroma (NM) is caused by the damage of the interdigital nerve located between the third and fourth metatarsal. Treatment is multidisciplinary and is aimed at relieving pain. Available alternatives include surgical procedures and physical therapy. Therefore, the aim of the study was to provide a comprehensive overview of the available treatments that health professionals can apply by choosing the best option and individual therapy for each patient. The methodology consisted of a search for scientific articles in the databases like PubMed, Google Scholar and Springerlink. To do this, keywords such as Morton's neuroma, surgery, physiotherapy were combined with the Boolean operators AND, OR and NOT. The results showed that physical therapy is indicated for the treatment of pain even before surgery or when patients are not candidates for surgical intervention. Its maximum effect lasts about 6 months. In contrast, surgery can reduce discomfort completely. It was concluded that according to the evidence reviewed, surgery is the treatment of choice because in the long term patients experience a total reduction of pain and the effects are sustained over time.

Introduction: Spiegel-Casseri’s hernia (HSC) is an infrequent entity that represents about 2 % of abdominal wall herniary defects, but frequency could be increased due to its subdiagnosis. The diagnosis of HSC is usually diffi cult and unsuspected and it presents high risk of jamming and strangulation so its surgical management is imperative. A TC is essential for diagnosis. Case report: Male, with pathological antecedents of myasthenia gravis, who consults about bilateral inguinal hernia and left Spiegel-Casseri’s hernia. Due to his clinical history, an open preperitoneal surgical approach with Lichtenstein plastic to repair all the three defects is done. During the postoperative, he had a bruise on the dropped hernial sac, treated with conservative measures and control and didn’t require drainage. Discussion: Most series of notifi ed cases of HSC in the literature show variable incidence of attendant abdominal wall’s defects. In this case, myasthenia gravis, a chronic and weakening disease, prompted three associated parietal defects and limited anesthesiologist options and surgical approaches. HSC is an unusual entity and its association with others hernias even more, but it exists and must be taken into account to achieve an optimal treatment for the patient. [ABSTRACT FROM AUTHOR]

Introduction: parosteal osteosarcoma is an extramedullary malignant bone tumor in which cells produce osteoid, represents less than 5% of all osteosarcomas, it occurs predominantly in women between the second and fourth decade of life. It is often located in the distal region of the femur and proximal tibia. Clinically it presents with increased volume and thigh or knee pain. Due to its low incidence and clinical features, a clinical case of femoral parosteal osteosarcoma is presented, with description of the surgical technique performed. Case report: a 14-year-old female presented with a 6-month history of increased volume and right thigh pain. Radiological studies revealed a bone lesion with malignant characteristics, for which she was sent to third-level hospital where oncology study protocol was set up; consisting in two percutaneous biopsies of the lesion with Jamshidi needle, which were histopathology reported as negative for malignant cells. The pulmonary high-resolution computed tomography showed metastasis and a Tc-99m MDP bone scintigraphy showed increased osteoblastic activity in the right femoral shaft. Given the results, is confirmed the need of en-bloc resection and intercalary prosthesis implantation with adjuvant chemotherapy. Conclusion: the intercalary prosthesis is a suitable therapeutic option in limb-salvage surgery for patients with femoral parosteal osteosarcoma. [ABSTRACT FROM AUTHOR]

Background: Neonatal surgery is one of the most specialized and demanding areas of pediatric surgery due to the specific anatomical and physiological characteristics of this vulnerable group of patients. This study aimed to present the experience of 10 years of neonatal surgical management in a secondary care perinatal hospital in Mexico. Methods: We conducted a descriptive, observational, cross-sectional, and retrospective study in a perinatal hospital in Toluca, Mexico, from August 01, 2012, to July 31, 2022. We included patients who underwent surgery within the hospital facilities by the Service of Pediatric Surgery. We studied demographic, clinical, and surgical variables and performed descriptive and inferential statistics. Results: A total of 551 patients underwent surgery during this period with a prevalence of 0.5%. The number of patients operated in the neonatal period was 497 (90.1%). Forty-eight pathologies were recorded, with a predominance of congenital malformations in 64.6% and prenatal diagnosis in 40.5% of cases. The survival rate was 89.7%. In the bivariate analysis of mortality, we found an inverse relationship between weight and gestational age (p < 0.05). Conclusion: Although not a local or national reference center, the hospital where the study was conducted treats various congenital and acquired diseases, with a mortality rate that tends to decrease, close to the international average, and lower than national reports.

La cirugía radioguiada emplea fuentes radioactivas para identificar y extirpar lesiones de difícil localización. Los tumores mesenquimales constituyen un grupo heterogéneo de neoplasias derivados del mesodermo, incluyendo lesiones benignas y sarcomas malignos. El objetivo de este estudio fue evaluar la capacidad de la semilla radioactiva de 125I para guiar la localización intraoperatoria de tumores mesenquimales, analizando sus tasas de complicación y evaluando los márgenes de las piezas quirúrgicas recuperadas. Estudio observacional retrospectivo de todos los pacientes consecutivos sometidos a cirugía radioguiada de un tumor mesenquimal con semilla radioactiva de 125I desde enero de 2012 hasta enero de 2020 en un centro de referencia terciario en España. La semilla fue insertada mediante punción percutánea guiada con ecografía o tomografía computarizada de forma ambulatoria. Se extirparon 15 lesiones en 11 cirugías a 11 pacientes, recuperando todas las lesiones marcadas (100%) con semilla de 125I. Las lesiones incluyeron áreas de fibrosis benigna (26,7%), angiofibroma celular (6,7%), tumor desmoide (20%), tumor fibroso solitario (13,3%), condrosarcoma (6,7%) y sarcoma pleomórfico (26,7%), con una tasa elevada de tumores recurrentes (60%). Solo hubo una complicación (6,7%) por caída de la semilla dentro del lecho quirúrgico. Según la clasificación de la Union for International Cancer Control de tumor residual, el 80% de las lesiones resultaron en una resección R0, el 6,7% fueron una resección R1 y el 13,3% fueron una resección R2. La cirugía radioguiada fue una técnica precisa para la extirpación de tumores mesenquimales de difícil localización. Radioguided surgery uses radioactive substances to identify and remove hard-to-locate lesions. Mesenchymal tumors constitute a heterogeneous group of neoplasms derived from the mesoderm, including benign lesions and malignant sarcomas. The aim of this study was to evaluate the ability of the 125I radioactive seed to guide intraoperative localization of mesenchymal tumors, analyzing its complication rates and evaluating the margins of the surgical specimens retrieved. Retrospective observational study of all consecutive patients undergoing radioguided surgery of a mesenchymal tumor with a 125I radioactive seed from January 2012 to January 2020 at a tertiary referral center in Spain. The seed was inserted percutaneously guided by ultrasound or computed tomography on an outpatient setting. Fifteen lesions were removed in 11 surgeries on 11 patients, recovering all marked lesions (100%) with a 125I seed. The lesions included areas of benign fibrosis (26.7%), cellular angiofibroma (6.7%), desmoid tumor (20%), solitary fibrous tumor (13.3%), chondrosarcoma (6.7%), and pleomorphic sarcoma (26.7%), with a high rate of recurrent tumors (60%). There was only one complication (6.7%) due to the seed falling within the surgical bed. According to the UICC classification of residual tumor, 80% of the lesions resulted in an R0 resection, 6.7% were an R1 resection, and 13.3% were an R2 resection. Radioguided surgery was a precise technique for the removal of hard-to-locate mesenchymal tumors. [ABSTRACT FROM AUTHOR]

Introduction: atlas assimilation can occur alone or in association with other craniocervical junction malformations and deformities. The etiological and pathological mechanisms are not clear. Case presentation: patient in her sixth decade of life, who was treated at the «Eugenio Espejo» Hospital, with asymmetric pyramidal symptoms after a low-energy kinetic fall. The condition completely reverted with conservative management. The patient is currently under periodic observation. Conclusion: the atlas assimilation, a congenital malformation, often asymptomatic; it is part of an embryological compensation when it is associated with other malformations. The appearance of deformity is necessary to reach atlantoaxial instability that it is not early. The knowledge of the concepts and distinction of the craniocervical junction abnormalities allows to indicate the best treatment in order to obtain the most suitable results with the individualization of each case.

The study intended to evaluate the incidence and evolution of sacroiliac joint dysfunction (SIJD). To reach 50 patients with SIJD diagnosis, 192 patients with low back pain and failure in conservative approach were consecutively examined (26% incidence). Initially patients underwent intra-articular (IA) corticosteroid sacroiliac joint (SIJ) block followed, if necessary, by cooled SIJ radiofrequency or referred to surgical intervention, in order of complexity. From the 50 patients submitted to IA SI block, 41 (82%) referred pain and quality of life improvement and lesser rescue analgesics consumption for 25 weeks. The block induced a prompt onset of pain relief and there was a drop in mean pain score from 8 to 2 cm (p < 0.001) maintained up to 25 weeks. Rescue analgesic consumption also significantly dropped (p < 0.05). However, nine patients (18%) did not refer long lasting improvement in the third week evaluation and underwent cooled radiofrequency. From this population of nine, seven were successful (78%) while two were recommended surgery. In view of the 50 patients, 82% were comfortable after IA block, 18% were submitted to radiofrequency, with a success rate of 78%. The final incidence of surgery suggestion was 4%.

Introduction: hip revision arthroplasty surgery is a surgical procedure that has been growing in recent years. Revision total hip arthroplasty (THA) is a notable surgical challenge due to the technical difficulty of the surgery itself. Complications of revision surgery includes dislocation, aseptic loosening, and infection. Objective: to compare the clinical-radiological results, as well as the incidence of complications, of two independent samples of patients who underwent revision total hip arthroplasty (rTHA) with mild-moderate acetabular defects using dual mobility implants compared to monopolar implants. Material and methods: retrospective comparative study of two cohorts of 30 patients who underwent acetabular revision surgery using large 36 mm monopolar heads or dual mobility respectively. All patients had Paprosky type I or II acetabular defects. The results on the VAS scale, WOMAC, and Harry hip score (HHS) were evaluated pre and postoperatively in both cohorts. Likewise, the incidence of postoperative complications and the survival rate between both groups were analyzed. Results: mean follow-up was 5.8 years (1-10.3 years). The difference between the pre and postoperative results in each cohort was significant for the VAS, WOMAC and HHS scale. The differences obtained in these scales between the different study groups did not find significant differences. The incidence of postoperative complications between both cohorts was similar, without finding significant differences. Conclusions: we consider that dual mobility does not provide superiority in terms of clinical-functional results and incidence of postoperative complications with respect to monopolar assemblies in acetabular revision surgery with mild-moderate defects.

Currently there is still little information about multilevel vertebral fractures (MVF), in addition to the fact that there are no classifications that help us group them in a simpler way, and guide us on their prognosis. The objective of this work is to propose a new classification of continuous type MVF, based on the number of end plates injured of the vertebral bodies and their severity, where we form four groups. A review of continuous MVF cases that we found in our hospital over a 6-year period was carried out, managing to designate 100% of the fractures, by their characteristics, to the corresponding group. In addition, we observed a better neurological prognosis in group 1. This classification is a proposal that will help us to group these injuries, that can be very varied, in only four groups; with the aim of later creating a more standardized management proposal, and knowing its neurological prognosis.

La resección quirúrgica se considera el tratamiento curativo por excelencia para los pacientes con tumores hepáticos primarios o metastásicos. Sin embargo, menos de 40% de ellos son candidatos a cirugía, ya sea por factores no modificables (comorbilidades, edad, disfunción hepática...), como por la invasión o proximidad del tumor a los principales pedículos vasculares, la falta de un futuro remanente hepático (FRH) adecuado para mantener una función hepática postoperatoria, o criterios de tamaño y numero tumoral. En estos últimos factores, la radioembolización hepática ha mostrado tener un papel como herramienta prequirúrgica, ya sea mediante la hipertrofia del FRH o mediante la reducción del tamaño tumoral que consigue disminuir la estadificación tumoral (término conocido como « downstaging »). A estos se suma un tercer factor, que es su capacidad de aplicar el test del tiempo, que permite identificar aquellos pacientes que presenten en un plazo corto de tiempo progresión de la enfermedad (tanto a nivel local como a distancia), evitándoles una cirugía innecesaria. En este trabajo se pretende hacer una revisión de la radioembolización como herramienta facilitadora de la cirugía hepática, tanto a través de la experiencia de nuestro centro como de la evidencia científica disponible. Surgical resection is considered the curative treatment par excellence for patients with primary or metastatic liver tumors. However, less than 40% of them are candidates for surgery, either due to non-modifiable factors (comorbidities, age, liver dysfunction...), or to the invasion or proximity of the tumor to the main vascular requirements, the lack of a future liver remnant (FLR) adequate to maintain postoperative liver function, or criteria of tumor size and number. In these last factors, hepatic radioembolization has been shown to play a role as a presurgical tool, either by hypertrophy of the FLR or by reducing tumor size that manages to reduce tumor staging (term known as "downstaging"). To these is added a third factor, which is its ability to apply the test of time, which makes it possible to identify those patients who present progression of the disease in a short period of time (both locally and at distance), avoiding a unnecessary surgery. This paper aims to review RE as a tool to facilitate liver surgery, both through the experience of our center and the available scientific evidence. [ABSTRACT FROM AUTHOR]
