Introduction: Pelvic fractures are frequently associated with high-energy trauma. Mortality varies from 5%-46%. In these patients, the factors related to poor outcomes are still controversial. Purpose: To explore if the variables analyzed were related with the long term outcomes of the treatment of an anterior-posterior compression type II pelvic fracture (APCII; AO/OTA: 61B2.3). Materials and Methods: 79 cases were analyzed and 23 patients remained for evaluation according to inclusion and exclusion criteria. Pelvic radiographs (anteroposterior, inlet and outlet) and CT-scans were evaluated. The Young & Burgess classification was used to define the fracture pattern and the Majeed Score for clinical outcomes. Variables analyzed: emergency treatment, associated injuries, delay for definitive fixation, method of fixation, quality of immediate postoperative reduction and surgical site infection. Results: We did not find any statistical relation between the type of emergency treatment, associated injuries, delay for definitive fixation, method of fixation, and the long-term clinical outcome. Patients who had an immediate postoperative reduction of less than 1 cm and those who did not have a surgical site infection obtained better functional outcomes (statistically significant). Conclusion: The quality variables of immediate postoperative reduction and surgical site infection in patients with APCII pelvic fracture had a direct relation with long-term functional and clinical outcomes.

Extraskeletal osteosarcoma (EOS) is a high-grade malignant tumor that accounts for less than 2% of soft tissue sarcomas and mainly engages people between the fifth and sixth decade of life. It is typically of late diagnosis, with an extensive symptomdiagnosis period greater than 6 months compared to conventional osteosarcoma. We report the case of a 43-year-old patient who presented in our service with a 1-year-old tumor localized in the gluteal and left thigh region. After inconclusive paraclinical studies and biopsy, the tumor was surgically resected with wide margins and diagnosed as EOS after the histological analysis of the piece. The patient showed a very good clinical and paraclinical progression without signs of local or distant recurrence after 20 months of follow-up.

Objectives: Lipoblastoma is a rare benign neoplasm that resembles white fat and can occur as a localized (lipoblastoma) or diffuse (lipoblastomatosis) tumor. Due to its rarity, the literature is mostly limited to case reports. The purpose of this study was to determine the local recurrence rate and complications after marginal resection of lipoblastomas located in the extremities or the back. Materials and Methods: We performed a multicenter retrospective review of the records of pediatric patients who had undergone surgical excision of lipoblastomas at 4 tertiary care institutions from 2008 to 2018. We recorded the demographic data, diagnostic method, the volume of the lesion, type of biopsy, complications, recurrence, and the need for additional procedures. Results: Throughout the study, 17 patients met the inclusion criteria for evaluation. The average patient age was 3.9 years, and 65% were male. The most common locations included thighs (N 9), low back region (N 2), and buttocks (N 2). The mean preoperative mass volume was 305.5 cm3 (range: 10.2 cm3 - 1745.8 cm3). The mean duration of follow-up was 2.8 years (range: 8 months to 5.6 years). One patient experienced recurrence (5.9%). One patient had a retracted skin scarring in the gluteal area. Conclusion: Marginal surgical resection of lipoblastomas located in the back or extremities showed a low recurrence rate at 2.8 years of follow-up and minimal complications.

Introduction: Talar neck fractures are rare but present a high rate of complications and reoperations. The objective of this work was to analyze and describe the complications in the medium and long term in 20 patients with talar neck fracture. Our hypothesis was that, in severe injuries, ORIF presents a high rate of complications that will require new surgical interventions. Materials and Methods: We evaluated 20 patients with talar neck fracture: 6 Hawkins II (29%), 11 Hawkins III (52%), and 3 Hawkins IV (19%). The mean follow-up was 11 years. We analyzed the fracture pattern (simple or comminuted), the presence of associated injuries, complications, and the need to perform a new surgical procedure. Results: 11 (55%) had associated injuries and 14 (70%) had comminution in the fracture line. We presented complications in 15 patients (75%). 9 (45%) patients required a second intervention to treat the complication. Discussion: The factors most related to the development of complications and the need for a new intervention are: comminution in the fracture line, associated injuries in the ipsilateral lower limb, Hawkins type III and IV fractures, and exposed fractures. We believe that in severe talar neck injuries (Hawkins type III and IV) with one or more of these factors, primary arthrodesis reduces the risk of complications and new surgeries and shortens recovery time.

Objective: The purpose of this study is to analyze arthroscopic findings in Maisonneuve lesions treated by arthroscopicallyassisted reduction and percutaneous fixation. Materials and Methods: We evaluated the registry of patients operated on between May 2013-January 2019 with acute Maisonneuve lesions, treated by arthroscopically-assisted reduction and percutaneous fixation. We analyzed arthroscopic findings (chondral or osteochondral lesions, intra-articular loose fragments, injury of the distal tibiofibular joint with or without instability, and injury of the deltoid ligament with or without medial instability). Results: 13 ankles in 13 patients were evaluated. 100% evidenced injury of the anterior distal tibiofibular ligament and instability of the distal tibiofibular joint. 92.30% had medial structure injuries, 76.9% with complete deltoid ligament injury with instability and 15.38% with medial malleolus fractures. In 1 patient (7.69%), no medial injury was evidenced. 84.61% of patients presented chondral or osteochondral lesions. 53.84% (7 patients) of cases had intra-articular loose fragments. Conclusion: Maisonneuve lesions are a consequence of high-energy trauma and present with a high incidence of intra-articular structure injuries (ligaments and articular surface). Arthroscopy is a very useful tool to identify and treat intra-articular injuries, which would otherwise not be recognized.

This report aims to review the different treatment options for plantar fasciitis. We conducted a virtual survey of foot and ankle specialists in our country where we asked for their opinion on the treatment of plantar fasciitis. The results varied, which shows that there is no single response to chronic treatment. Conclusion: Plantar fasciitis is a frequent, painful condition. The origin is unknown, but the association with multiple factors is known. Many treatment modalities have been recommended, including drugs, physiotherapy, orthotic devices, and surgery, but no report analyzes the effectiveness of each of them separately or categorically confirms its benefits.

Introducción: La lesión de la arteria vertebral es un evento grave. El objetivo del estudio fue evaluar el grado de conocimiento de los cirujanos de columna en la Argentina sobre las medidas diagnósticas y terapéuticas de la lesión de la arteria vertebral. Materiales y Métodos: Se realizó un estudio descriptivo observacional mediante una encuesta difundida a través de la AANC y la SAPCV. Resultados: Se recibieron157 respuestas. El 47,4% considera relevante evaluar la anatomía de la arteria vertebral en todo tipo de patología mediante métodos angiográficos. La mitad de los encuestados diagnosticó una variante anatómica de la arteria. El 29,2% manifestó haber tenido en su práctica una lesión de la arteria. Solo el 35% tiene un protocolo de acción para el manejo de este evento adverso. El 77% adopta como primera medida el taponamiento. En el seguimiento posquirúrgico, la mayoría estudia el estado final mediante métodos angiográficos. Alrededor del 10% procuraría instaurar alguna medida de profilaxis antitrombótica. El 76,6% dispone de Servicio de Hemodinamia con cirujano endovascular. Conclusión: Esta complicación está subestimada. Menos de la mitad de los cirujanos utiliza, como rutina, herramientas de diagnóstico de posibles alteraciones anatómicas. No se han observado protocolos de manejo ni seguimiento de estas lesiones.

Introducción: La enfermedad de Paget es un trastorno metabólico de etiología desconocida, secundario a un incremento en la función de los osteoclastos y la consecuente respuesta de los osteoblastos a la formación exagerada de hueso. Compromete con mayor frecuencia el fémur proximal y, a menudo, se diagnostica incidentalmente. Se presenta el caso de una mujer con antecedente de enfermedad de Paget y pseudoartrosis de cadera izquierda, con indicaciones de prótesis total de cadera izquierda y un episodio único de luxación, sin complicaciones posteriores y una adecuada evolución. Conclusión: El manejo quirúrgico en casos de fractura de cadera permite restablecer la marcha y mejorar la calidad de vida de los pacientes con enfermedad de Paget. A pesar de ser una patología que dificulta el manejo de los pacientes, la enfermedad de Paget no es una contraindicación para la artroplastia total de cadera y permite mejorar el dolor y recuperar la funcionalidad

La artritis séptica acromioclavicular es un cuadro sumamente infrecuente que, por lo general, se presenta en articulaciones con alta vascularización, como cadera, rodilla y hombro. El microorganismo aislado con más frecuencia es Staphylococcus aureus. Describimos a una paciente de 56 años con artritis séptica acromioclavicular, que requirió una intervención quirúrgica de urgencia. Otra particularidad del caso es el germen aislado, Staphylococcus argenteus, una bacteria muy infrecuente en este tipo de enfermedad.

Introduction: Fractures of the medial and distal tibial segment often occur in young patients with high-energy trauma and older patients with low-energy trauma. The objective of this study is to compare the time of surgery, time of use of fluoroscopy, functional outcomes, and postoperative pain in patients treated with the suprapatellar vs. infrapatellar technique for tibial nailing. Materials and Methods: We carried out a retrospective study between March 2018 and October 2019. All the data was collected from the electronic clinical record (ECR). We included patients with diaphyseal and distal tibial fractures. The variables analyzed were: fluoroscopy and surgery time, pain evaluation, and functional outcomes of the patients using the Lysholm score. Results: 80 patients met all the inclusion criteria. Sociodemographic data were divided into 2 similar groups. The suprapatellar approach was used in 44 patients and the infrapatellar in 36 of them. A statistical difference was obtained in the analysis for the time of surgery, use of fluoroscopy, and pain evaluation in favor of the suprapatellar technique. Conclusions: The results of our study showed shorter surgery and fluoroscopy times with the use of the suprapatellar technique compared with the infrapatellar technique. The suprapatellar technique also yielded better pain results in the visual analog scale.
