Patients with trochanteric hip fractures and pre-existing osteoarthritis can be treated with nailing osteosynthesis without significant decrease in functional status.

PURPOSE: Functional outcome in patients after trochanteric fracture fixation with pre-existing radiographic osteoarthritis (OA) is unclear. Analyzing their function and independence, before and after fracture, could optimize their treatment and decrease the socioeconomic burden in this particular group. METHODS: The influence of pre-existing radiographic hip OA on functional outcome was retrospectively analyzed with a cohort of patients undergoing proximal femoral nailing for trochanteric fracture. OA was graded according to the Tonnis classification. Functional outcome was assessed preoperatively and 12 months after surgery by the Parker Mobility Score (PMS). We consider a meaningful reduction a difference between preoperatively PMS and 12 months after surgery ≥ 2. In order to evaluate if OA is related to PMS reduction ≥ 2, we calculate the SubHazard ratio (SHR) performing a competing risk regression model considering death as a competing risk event, adjusting by confounders. Death, reoperations, readmissions, surgical time, and fracture reduction quality in patients with and without osteoarthritis were recorded. RESULTS: 375 trochanteric hip fractures treated with cephalomedullary nails were included, from which 80 (21% CI95% 17%-21%) were classified as Tonnis 2 or 3. This group of patients with pre-existing OA was significantly older (mean age of 88.6 [SD 5.65] vs 85.5 years [SD 6.95]) than the group without OA. The preoperatively PMS score was 6.28 (2.71) in non-OA patients and 5.69 (2.67) in OA patients. The mean PMS reduction 12 months after surgery was 1.3 (SD 2.05) in OA patients and 1.07 (SD 2.2) in non-OA patients (p = 0.43). Competing risks analysis, adjusted by confounders had an SHR of 1.15 (IC95% 0.77 - 1.69). Death, readmission, reoperations, surgical time, and fracture reduction quality did not differ in both groups. CONCLUSIONS: Patients with pre-existing radiographic OA treated with femoral nailing have a similar reduction in functional outcomes compared to the non-OA group at one-year follow-up. Further studies will be needed to compare the results of the functional outcome in arthroplasty with those of femoral nailing for the treatment of trochanteric femur fractures in patients with OA.

Very early prescription of range of motion exercises in ankle fractures treated with ORIF does not increase the rate of complications and reoperations: A survival risk analysis.

BACKGROUND: Ankle fractures are commonly treated with non-surgical or surgical (preferably ORIF) approaches based on fracture characteristics. The postoperative care regimens vary widely, and the impact of very early mobilization on complications and reoperation rates in ankle fractures treated with ORIF remains unclear. METHODS: A retrospective analysis was conducted on ankle fractures treated between January 2014 and November 2020. Demographic and fracture characteristic data were collected. Very early prescription of range of motion exercises was defined as initiation within the first week after surgery, typically between the second and seventh postoperative day. Complications, reoperations, and time to these events were analyzed. Kaplan Meier survival analysis was performed to assess the risk of complications with very early mobilization. RESULTS: A total of 299 patients met the inclusion criteria. The cohort included 83 unimalleolar, 77 bimalleolar, and 138 trimalleolar fractures. Of the patients, 116 (38.8%) underwent very early range of motion. Complications occurred in 45 events among 39 patients (13%), with 16 events (41%) in the very early range of motion group. Reoperations were required for 23 patients (3.67% of the cohort). No statistically significant differences were found in the analysis of complications, with a hazard ratio (HR) of 1.17, and in the adjusted analysis with an HR of 1.12. Similarly, the reoperation analysis showed no significant differences, with an HR of 0.85 and 0.68 in the adjusted analysis. CONCLUSION: Very early prescription of range of motion exercises in ankle fractures treated with ORIF is a safe approach, as it does not increase the rates of complications or reoperations compared to early or late mobilization. This study supports the use of very early mobilization as a rehabilitation method for ankle fractures.

Outcomes, risk factors, and conversion rate in acetabular fractures in patients over 65 years of age. Analysis at a mean follow-up of 6 years.

INTRODUCTION: Acetabular fractures are devastating injuries that can affect patients of different ages, as well as being associated with high or low energy trauma. Conversion to total hip arthroplasty (THA) results in increased complication rates, resource use and costs compared to primary THA due to osteoarthritis. The aim of this paper is to describe a retrospective cohort of patients over 65 years of age who presented with an acetabular fracture and were treated with open reduction and internal fixation (ORIF). METHODS: A retrospective cohort study was conducted from January 2002 to December 2017. The study identified all patients over 65 years of age who suffered an acetabular fracture and were treated primarily with ORIF. The quality of reduction, fracture pattern and associated poor prognostic factors for fracture were analyzed. RESULTS: A total of 50 cases of acetabular fractures in patients over 65 years of age were included. Six of them required conversion to THA (12%). In 3 of these cases conversion surgery was performed because of pre-existing osteoarthritis, pain, and postoperative progression of osteoarthritis. The main factors involved in the conversion cases were intra-articular fragments, femoral head protrusion and posterior wall comminution. Postoperative intra-articular gap had a p = 0.01 in linear regression analysis for conversion to arthroplasty. CONCLUSION: The conversion rate reported in our cohort of elderly patients is similar to that reported in the literature in patients of all age ranges. The quality of reduction was a significant factor in predicting progression to conversion to THA.

Comparison between functionality and quality of reduction between suprapatellar vs infrapatellar approaches in the treatment of diaphyseal and distal tibial fractures.

INTRODUCTION: Intramedullary nailing is the most frequent procedure used for the treatment of tibial fractures that do not involve the articular surfaces. The goal of this study is to analyse the clinical outcomes, time of surgery and use of fluoroscopy in patients with midshaft and distal tibial fractures treated with suprapatellar and infrapatellar nailing and compare the results between these different groups. METHODS: A retrospective study was conducted, and patients were selected between the period of March 2018 and October 2019. The following variables were studied: age, gender, AO classification, time of surgery (minutes), time of fluoroscopy (seconds), quality of reduction in postoperative controls and 1 year follow-up (using the angles MPTA, LDTA, PPTA, ADTA). Functional outcomes were studied at 1 month and 1 year follow-up. The visual analogue scale was used to study and compare the postoperative pain of the patients. The Lysholm Knee Score was used to evaluate the functional outcomes of the patients. RESULTS: A total of 80 patients meeting the inclusion criteria were included in this study. The suprapatellar approach was used in 44 patients and the infrapatellar in 36 patients. The time of surgery (p=0.008) and the mean time of use of fluoroscopy (p <0.001) difference were significant in favour of the suprapatellar approach. In the quality of reduction analysis, we have statistically significant results in the LDTA and ADTA angles. Also, in the evaluation of postoperative pain, significant difference was found in favour of the suprapatellar approach. CONCLUSION: In conclusion, our study compared the suprapatellar approach and the infrapatellar approach for the treatment of midshaft and distal tibia fractures with intramedullary nailing. The results showed lesser time of surgery and use of fluoroscopy, lower knee pain, and lower rate of malalignment with the suprapatellar approach than with the infrapatellar approach.

Fractura de Tillaux en adultos. Reporte de un caso y revisión de la bibliografía / Tillaux fracture in adults. Case report and literature review

Introducción: La fractura de la región anterolateral de la epífisis distal de la tibia, o tubérculo de Tillaux-Chaput, es conocida como fractura de Tillaux. Se trata de una fractura extremadamente rara en los adultos, pero tiene una importancia fundamental, porque compromete la superficie articular tibio-astragalina, la estabilidad de la sindesmosis y, en algunos casos, la incisura peronea. Se presenta el caso de una mujer de 45 años con un traumatismo rotatorio del tobillo izquierdo e impotencia funcional y dolor en la región anterolateral del tobillo. Las radiografías generaron la sospecha de un trazo de fractura correspondiente al tubérculo de Tillaux-Chaput. Por lo tanto, se realizó una tomografía computarizada que confirmó una fractura de Tillaux, que tenía un desplazamiento >2 mm y compromiso de la incisura peronea. La paciente fue sometida a reducción abierta y fijación interna. La fractura consolidó a los 3 meses. Al año de la cirugía, su estado clínico y funcional es excelente. Conclusión: La sospecha diagnóstica que surge de una completa anamnesis y un meticuloso examen físico, y la confirmación mediante estudios por imágenes son esenciales para abordar correctamente patrones de fracturas raros, como la fractura de Tillaux. Nivel de Evidencia: IV

Introduction: The fracture of the anterolateral region of the distal tibial epiphysis, or Tillaux-Chaput tubercle, is known as Tillaux fracture. It is an exceptional entity in adults, but it has significant importance because it affects the tibiotalar joint surface, the stability of the syndesmosis, and, in some cases, the fibular notch. We present the case of a 45-year-old woman treated in the Emergency Service due to rotational trauma to the left ankle and functional impairment and pain in the anterolateral region of the ankle. The radiographs led to the suspicion of a fracture line corresponding to the Tillaux-Chaput tubercle. Therefore, a CT scan was performed, which confirmed a Tillaux fracture with a >2 mm displacement and involvement of the fibular notch. The patient underwent open reduction and internal fixation. The fracture consolidated after 3 months. One year after surgery, her clinical and functional status was excellent. Conclusion:Diagnostic suspicion through meticulous physical examination and anamnesis and confirmation by imaging studies are essential for the proper management of rare fracture patterns, such as Tillaux fractures.

Intramedullary nail for the surgical treatment of unstable fractures of the femur in previously amputated patients / [Clavo endomedular para el tratamiento quirúrgico de fracturas inestables de fémur en pacientes previamente amputados]

Introduction: Femoral fractures in previously amputated patients (PAP) have been poorly reported in international literature, however it is worth mentioning that advances in the manufacture of orthotics for lower limbs have allowed these patients to remain functionally active. Surgery is then an option but difficulties may appear in positioning the patient for surgery due to the absence of the foot or ankle from where to pull and optimize the fracture reduction. Objective: We report 3 cases of PAP with ipsilateral unstable femur fractures, treated surgically with cervicodiaphyseal endomedular nail. The surgical technique used in each case is described. Results: Good long-term results were obtained demonstrating the effectiveness of surgical treatment and the reduction technique used. Conclusion: Surgical treatment of unstable fractures of the proximal femur with an endomedullary nail should be considered a valid therapeutic option.

Introducción: Las fracturas de fémur en pacientes previamente amputados (PPA) han sido escasamente reportadas en la literatura internacional, sin embargo, cabe mencionar que los avances en la fabricación de ortesis para miembros inferiores han permitido que estos pacientes, se mantengan funcionalmente activos. La cirugía entonces es una opción, pero representa una dificultad en el posicionamiento del paciente a la hora de planificar su cirugía debido a la ausencia del pie o tobillo del cual traccionar y optimizar la reducción de la fractura. Objetivo: Reportamos a continuación 3 casos de PPA con fracturas inestables ipsilaterales de fémur, tratadas mediante reducción y osteosíntesis con clavo endomedular cervicodiafisario. Se describe la técnica quirúrgica utilizada en cada caso. Resultados: Se obtuvieron buenos resultados a largo plazo demostrando la efectividad del tratamiento quirúrgico y la técnica de reducción utilizada. Conclusión: El tratamiento quirúrgico de fracturas inestables de fémur proximal con clavo endomedular, ha de ser considerado una opción terapéutica válida.

The AO trauma CPP bone infection registry: Epidemiology and outcomes of Staphylococcus aureus bone infection.

Bone infection represents a serious complication of orthopedic surgery and Staphylococcus aureus is the most common pathogen. To improve the understanding of host-pathogen interaction, we developed a biospecimen registry (AO Trauma CPP Bone Infection Registry) to collect clinical data, bacterial isolates, and serum from patients with S. aureus bone infection. A prospective multinational registry with a 12-month follow-up was created to include adult patients (18 years or older) with culture-confirmed S. aureus infection in long bones after fracture fixation or arthroplasty. Baseline patient attributes and details on infections and treatments were recorded. Blood and serum samples were obtained at baseline, 6, and 12 months. Patient-reported outcomes were collected at 1, 6, and 12 months. Clinical outcomes were recorded. Two hundred and ninety-two patients with fracture-related infection (n = 157, 53.8%), prosthetic joint infection (n = 86, 29.5%), and osteomyelitis (n = 49, 16.8%) were enrolled. Methicillin-resistant S. aureus was detected in 82 patients (28.4%), with the highest proportion found among patients from North American sites (n = 39, 48.8%) and the lowest from Central European sites (n = 18, 12.2%). Patient outcomes improved at 6 and 12 months in comparison to baseline. The SF-36 physical component summary mean (95% confidence interval) score, however, did not reach 50 at 12 months. The cure rate at the end of the study period was 62.1%. Although patients improved with treatment, less than two-thirds were cured in 1 year. At 12-month follow-up, patient-reported outcome scores were worse for patients with methicillin-resistant S. aureus infections.

Versatilidad del clavo endomedular retrógrado largo de tibia para artrodesis tibio-talo-calcánea en pacientes con lesiones asociadas en el mismo segmento / Versatility of the tibia long retrograde intramedullary nail for tibiotalocalcaneal arthrodesis in patients with associated lesions in the same segment

Introducción: La afección articular que lleva a la necesidad de una artrodesis tibio-calcánea puede estar acompañada de una segunda lesión en el mismo segmento óseo, y los clavos de diseño para artrodesis no tienen la longitud adecuada para cubrir ambas lesiones. No hallamos opciones terapéuticas para este tipo de lesiones en la bibliografía. Objetivo: Presentar una serie de casos en los que se utilizó un único clavo de tibia (de colocación anterógrada) de forma retrógrada, con el doble objetivo de efectuar una artrodesis tibio-talo-calcánea, sumada al tratamiento de una lesión asociada en un mismo tiempo quirúrgico. Materiales y métodos: Se evaluó, en forma retrospectiva, desde septiembre de 2009 hasta junio de 2019, a un grupo de 12 pacientes que requirió una artrodesis tibio-talo-calcánea sumada a la necesidad de resolver simultáneamente un defecto secundario local. La edad promedio fue de 43.7 años, y el seguimiento global fue de 43.9 meses. Resultados: Todos los pacientes lograron una artrodesis tibio-calcánea constatada en radiografías de frente y de perfil, y el 83,3% recuperó el stock óseo de manera completa. Conclusión: Ante la ausencia en el mercado de osteosíntesis para resolver las patologías asociadas en un mismo paciente, proponemos el uso del clavo endomedular largo de tibia colocado de manera retrógrada como una opción de tratamiento, porque se ha demostrado que es eficaz para lograr la artrodesis tibio-calcánea. Además, se lo pudo utilizar como guía en el alargamiento y el transporte óseo, y como estabilización para tratar lesiones simultáneas. Nivel de Evidencia: IV

background: The joint condition that leads to the need for a tibiocalcaneal arthrodesis may be accompanied by a second injury in the same bone segment, and design nails for arthrodesis are not of adequate length to cover both injuries. We have not found therapeutic options for this type of injury in the literature. Objective: To present a series of cases where a single tibia nail (antegrade placement) was used retrogradely, with the dual objective of performing a tibiotalocalcaneal arthrodesis added to the treatment of an associated injury in the same surgical stage. materials and methods: We retrospectively evaluated a group of 12 patients who required a tibiotalocalcaneal arthrodesis as well as to simultaneously resolve a local secondary defect from September 2009 to June 2019. The average age was 43.7 (27-61) years, and the global follow-up was 43. 9 months. Results: All patients achieved a tibiocalcaneal arthrodesis confirmed in antero-posterior and lateral radiographs, and 83.3% of the patients recovered their bone stock completely. Conclusion: Faced with the lack of osteosynthesis in the market to resolve associated pathologies in the same patient, we propose the use of a long tibial intramedullary nail placed in a retrograde manner as a treatment option since it has proven to be efficient in achieving tibiocalcaneal arthrodesis. In addition, it could be used as a rail for bone lengthening and transport, and as stabilization to treat simultaneous injuries. Level of Evidence: IV

Soporte circunferencial posterior en fracturas de platillo tibial / Posterior circumferential support in tibial plateau fractures

Las técnicas quirúrgicas que más se utilizan en la actualidad para fracturas de platillo tibial no contemplan correctamente la conminución ósea multiplanar ni la presencia de fragmentos óseos posteriores. Nos hemos enfrentado con esta problemática al tratar a un paciente con fractura de platillo tibial tipo Schatzker VI, en la cual se suplementó la osteosíntesis habitualmente utilizada con una placa horizontal circunferencial posterior. Se logró la consolidación ósea y los resultados funcionales a corto plazo fueron buenos. Del análisis de la bibliografía citada, se concluye en que se han desarrollado varias técnicas de contención posterior de los platillos tibiales, y la osteosíntesis circunferencial es una técnica por considerar. Nivel de Evidencia: IV

Surgical techniques commonly used today for tibial plateau fractures do not properly contemplate multiplanar bone comminution nor the presence of posterior bone fragments. We have faced this problem when treating a patient with a Schatzker VI type fracture, in which the commonly used osteosynthesis was supplemented with a posterior horizontal circumferential plate. Bone consolidation and good results were achieved in the short term in the case we present. From the analysis of the cited literature, we concluded that several techniques for containing posterior tibial plateau bone comminution have been developed. Among them, circumferential osteosynthesis is a technique to take into account. Level of Evidence: IV

Impact of anticoagulants in elderly patients who suffer a hip fracture. Should we have a different approach?

INTRODUCTION: Hip fracture in the elderly is a frequent problem. Chronic treatment with anticoagulants is common in these patients, and may delay surgery. OBJECTIVES: To compare time to surgery, hospital stay, in-hospital and 90 days complications between anticoagulated (A) and non-anticoagulated (NA) groups. METHODS: Retrospective cohort of >64 years-old patients with acute hip fracture. Period June-2014 to December 2019. We estimated crude and adjusted OR (95%CI) for in-hospital complications with logistic regression model. We report the crude and adjusted HR for readmission and 90-day mortality with Cox proportional hazards model. RESULTS: Of the 1058 patients, 123 (11%) were anticoagulated. Time to surgery was 26.4 hours (IIQ 13.9-48) in A and 24 hours (IIQ 2.3-48) in NA, p0.001. Hospital stay was 7 days (IIQ 5-9) in A and 6 days (IIQ 5-10.5) NA, p0,000. In-hospital complications were 17 (14%) in A and 81 (9%) in NA, p0.064. The adjusted OR was 1.53 (95%CI 0.8-2.7) p0.138. For 90-day readmission, the crude HR was 1.51 (95%CI 0.99-2.29) p0.053 and the adjusted HR was 1.31 (95%CI 0.85-2.00) p0,09. For 90-day mortality, the crude HR was 0.80 (95%CI 0.45-1.43) p0.464 and the adjusted HR was 0.70 (95% CI 0.39-1.25) p0.239. DISCUSSION: While we found differences between groups in time to surgery and hospital statistics, their clinical relevance should be reviewed.

Cement leakage into the hip joint during TFN-A cement augmentation in a revision surgery of an extra-capsular hip fracture.

INTRODUCTION: The intra-articular migration of the spiral lamina or screw, after close reduction and internal fixation (CRIF) with an intramedullary cervicodiaphyseal nail (cut-through), is one of the most frequent postoperative complications. We present a patient with a cut-through and cement leakage into the hip joint after TFN-A cement augmentation and spiral lamina replacement. METHODS: A 83-year-old man, suffered a cut-through after CRIF of his left extracapsular hip fracture during the third postoperative month. A revision surgery was planned, including spiral lamina replacement and cement augmentation. Cement leakage into the hip joint was confirmed in the immediate postoperative radiograph and a new intervention was indicated with the removal of the third bodies. RESULTS: The patient presented good clinical evolution, without functional limitation or pain. In routinely postoperative radiographic controls, no differences were observed respect to the immediate postoperative one. DISCUSSION: Current literature dealing with implant revision surgery and associated cement augmentation are scarce. CONCLUSION: As far as we are concerned, this is the first case in the literature of a re-revision surgery of an extracapsular hip fracture due to a three months postoperative cut-through and a posterior cement leakage into the hip joint after TFN-A cement augmentation and spiral lamina replacement with the need of a posterolateral approach for removal.

INTRODUCCIÓN: El anciano con fractura de cadera tiene alto riesgo de complicaciones y mortalidad hospitalaria. Las estadías hospitalarias cortas y el alta temprana con problemas clínicos activos pueden llevar a reinternaciones. OBJETIVOS: conocer la tasa de reinternaciones, los motivos y las variables predictoras de las mismas en los sujetos que tuvieron fracturas de cadera. MÉTODOS: Se trabajó una cohorte retrospectiva. Se incluyó a todos los pacientes ingresados en el Registro Institucional de Ancianos con Fractura de Cadera entre julio de 2014 y julio de 2017. Se describió la tasa de reinternación y su IC95%. Se utilizó un modelo de riesgo proporcional de Cox para describir factores de riesgo y el tiempo a la reinternación. RESULTADOS: Se incluyó a 858 pacientes. La mediana de días de internación fue de 6 (rango intercuartil [RIC 5-9]). El 86% (737) de los pacientes era de sexo femenino, con una mediana de edad de 86 años (RIC 81-89). La tasa de reinternación a los 30 días fue de 10% (IC95%: 8,3-12,5) y al año, de 39% (IC95%: 34,8-42,6). La principal causa fue la infección (30%). Los factores asociados fueron: edad (>85 años) Razón de Hazard o Hazard ratio (HR)1,3 (IC95%: 1-1,7; p 0,03), sexo femenino HR 0,5 (IC95%: 0,4-0,7; p<0,01), fragilidad HR 1,4 (IC95%: 1,1-1,8; p<0,01), score de Charlson (≥2) HR 1,6 (IC95%: 1,3-2,1; p<0,01), días de internación (>7 días) HR 1,4 (IC95%: 1,2-1,9; p<0,01). CONCLUSIONES: La reinternación después de una fractura de cadera tiene alta incidencia. El cuidado perioperatorio de los pacientes con fractura de cadera es esencial para reducir las complicaciones.

INTRODUCTION: Elderly patients with hip fracture are at high risk for complications and in-hospital mortality. Short hospital stay and early discharge with still active clinical problems may lead to readmissions. OBJECTIVES: to know the rate of readmissions, the reasons and the predictive variables in patients who had hip fractures. METHODS: A retrospective cohort study was performed, with all patients included in the institutional registry of elderly patients with hip fracture between July 2014 and July 2017. Readmission rates and their CI95% were described. A proportional risk Cox model was used to describe risk factors and time-toreadmission. RESULTS: A total of 858 patients were included with a median hospital stay of 6 days (interquartile range [IQR] 5-9), 86% (737) of female patients and a median age of 86 years (IQR 81-89). Readmission rates were 10% (CI95%: 8.3-12.5) at 30 days and 39% (CI95%: 34.8-42.6) at 12 months. The main cause was infection (30%). Associated factors were: age (>85 years) HR 1.3 (CI95%: 1-1.7; p 0.03), female gender HR 0.5 (CI95%: 0.4-0.7; p<0.01), fragility HR 1.4 (CI95%: 1.1-1.8; p<0.01), Charlson score (≥2) HR 1.6 (CI95%: 1.3-2.1; p<0.01), hospital stay (>7 days) HR 1.4 (CI95%: 1.2- 1.9, p<0.01). CONCLUSIONS: Readmission after hip fracture has a high incidence. Perioperative care of patients with hip fracture is essential to reduce complications.

Introduction: Coverage defects in the leg are a challenge due to the particulars of the anatomy in said area, different reconstruction strategies have been developed, being the fasciocutaneous perforator flaps the most frequently used. The aim of this paper is to discuss the therapeutic alternative and to describe the surgical technique, the results and the complications of the posterior tibial artery perforator flap (PTAPF) to treat coverage defects. Materials and Methods: We performed a retrospective review of patients treated with a fasciocutaneous flap. We analyzed preoperative demographic variables. The surgical technique and the indications in each patient are described. Finally, the postoperative variables, such as complications and flap survival, were analyzed. Results: Twelve patients (all male) treated with PTAPF were included. The average age at the time of surgery was 52 years (range: 29-77 years). The maximum follow-up was 55 months, with a minimum of 5 months (average: 18 months). There were two flaps with transient congestion that reverted spontaneously: one partial failure and one total failure. Conclusions: PTAPF should be considered a viable option for the treatment of small- and medium-sized leg wounds, since they provide similar tissue thickness, texture and color on the recipient site, achieving good clinical and cosmetic results.

Nutrition and Inflammation Influence 1-Year Mortality of Surgically Treated Elderly Intertrochanteric Fractures: A Prospective International Multicenter Case Series.

INTRODUCTION: Hip fracture is a common and devastating event in older adults causing increased dependence, comorbidity, and mortality. Since new surgical techniques have not significantly improved the mortality rate, a better understanding of patient risk factors could improve the treatment algorithm and outcomes. This prospective study aimed to document the 1-year survival rate of patients with intertrochanteric fracture treated surgically in Latin America and to investigate risk factors associated with 1-year mortality. PATIENTS AND METHODS: Between January 2013 and March 2015, 199 patients were prospectively enrolled. Inclusion criteria were aged 60 years or older, isolated intertrochanteric fracture (AO/OTA 31-A), and time to surgery within 10 days after injury. The follow-up period was 1 year. The association between mortality and patient demographics, comorbidity, surgical details, and preoperative laboratory parameters was assessed using log-rank tests. RESULTS: Twenty patients died by 365 days after surgery (including 5 that died within 30 days of surgery) resulting in a 1-year survival rate of 89.8% (95% confidence interval = 84.6-93.3). The 1-year mortality was significantly associated with age (≥85 years old, P = .032), existing comorbidity (P = .002), preinjury mobility level (P = .026), mental state (Mini-Mental State Examination > 23, P = .040), low preoperative plasma albumin level (P = .007), and high preoperative blood C-reactive protein level (CRP; P = .012). At the 1-year follow-up, patients on average did not regain their preinjury hip function and mobility, although the self-assessed quality of life was equal or better than before the injury. DISCUSSION: As a prospective study, the current patient population had clear inclusion and exclusion criteria and was relatively homogeneous. The resulting associations between 1-year postoperative mortality and preoperative hypoalbuminemia and preoperative elevated CRP level are therefore especially notable. Previously identified risk factors such as male gender and time to surgery showed no significant association with 1-year mortality-the overall favorable condition of the current population or the lack of statistical power maybe responsible for this observation. CONCLUSION: The current results showed that under the condition of optimal surgical treatment and low surgery-related complication, preinjury health status as indicated by the blood level of albumin and CRP has a direct and significant impact on 1-year mortality rate.

Tratamiento de la osteomielitis asociada a úlceras alrededor de la pelvis / Treatment of pressure ulcer-related pelvic osteomyelitis

Introducción: El tratamiento de la osteomielitis crónica asociada a úlceras alrededor de la pelvis es complejo y multidisciplinario. Un tratamiento antibiótico, dirigido a más de un microorganismo, sumado a la cirugía permitiría disminuir la recurrencia de la infección. El objetivo de este estudio fue analizar los resultados en pacientes con osteomielitis crónica asociada a úlceras por presión, con gran defecto de cobertura alrededor de la pelvis, tratados con desbridamiento del lecho y un colgajo para el defecto de cobertura. Materiales y Métodos: Se realizó un estudio descriptivo, retrospectivo, basado en los datos de las historias clínicas de pacientes que requirieron cobertura quirúrgica de úlceras por presión, entre octubre de 2010 y febrero de 2017. Los pacientes fueron tratados con un procedimiento en dos tiempos quirúrgicos: desbridamiento y luego colgajo de cobertura del defecto remanente. Resultados: Se trataron 27 úlceras (9 sacras, 13 isquiáticas y 5 trocantéricas) en 15 pacientes (edad promedio 44. 9 años [rango 22-81]). Tres úlceras desarrollaron un solo germen, en el resto, los cultivos fueron polimicrobianos. Se administraron antibióticos intravenosos durante un mínimo de 4-6 semanas. Los valores iniciales de eritrosedimentación y proteína C reactiva ultrasensible fueron 72 mm/h y 55 mg/l, respectivamente, y disminuyeron a 49 mm/h y 20 mg/l, respectivamente, a los 3 meses. Conclusiones: Nuestro protocolo acorta los tiempos de tratamiento, ya que no se espera a terminar la antibioticoterapia para realizar el colgajo. Consideramos que la cobertura inmediata del defecto de partes blandas permite controlar el acceso de nuevos microorganismos a la región afectada. Así hemos obtenido buenos resultados con una baja tasa de recidiva comparada con la de otras series. Nivel de Evidencia: IV

Introduction: Treatment of chronic osteomyelitis secondary to pressure ulcers around the pelvis is complex and multidisciplinary. Antibiotic treatment, usually aimed at more than one microorganism, in addition to surgery would reduce the recurrence of infection. The goal of this study was to analyze results in patients with pressure ulcer-related osteomyelitis around the pelvis, being treated with debridement and a flap to cover the soft tissue defect. Methods: A descriptive, retrospective study was carried out with data obtained from medical records of patients requiring surgical coverage of pressure sores, between October 2010 and February 2017. Patients were treated in two surgical times: debridement and then a flap to fill the remaining soft tissue defect. Results: Twenty-seven pressure ulcers were treated (sacral 9, ischial 13, trochanteric 5) in 15 patients (average age 44. 9 years [range 22-81]). Only a single microorganism was detected in three ulcers, the remaining ulcers developed more than one microorganism. Intravenous antibiotics for at least 4-6 weeks were administered. Initially erythrocyte sedimentation rate and ultrasensitive protein C reactive values were 72 mm/h and 55 mg/L, respectively, after three months of flap surgery, and they decreased to 49 mm/h and 20 mg/L, respectively. Conclusions: Our protocol reduces length of treatment, since we do not wait until the cessation of antibiotics to perform the flap. We consider that soft tissues defect coverage as soon as possible reduces colonization of new microorganisms in the involved region. We obtained good results with a low recurrence rate compared to other series. Level of Evidence: IV

Fractura de miembro inferior de alta energía asociada a lesión multiligamentaria de rodilla / Multiligament knee injuries with high energy limb fractures

Introducción: La lesión multiligamentaria de la rodilla en pacientes con fracturas del miembro inferior ipsilateral es una entidad poco frecuente y que suele pasar desapercibida en la etapa aguda. El objetivo de este trabajo es analizar una serie de pacientes con fractura de miembro inferior asociado a lesión multiligamentaria de rodilla. Materiales y método: Se realizó una búsqueda retrospectiva de enero 2010 a diciembre 2016, de aquellos pacientes atendidos en nuestro centro con fractura de miembro inferior asociada a inestabilidad multidireccional de la rodilla ipsilateral. Se evaluó el patrón de fractura, la lesión ligamentaria asociada, si presentaba Resonancia Magnética (RM) inicial que pesquisara el diagnóstico de dicha lesión, y la decisión del momento del tratamiento quirúrgico. Se realizó una valoración del dolor con la Escala Visual Analógica (EVA) y funcional con escala de Lysholm y Tegner a todos aquellos pacientes con más de 12 meses de evolución postoperatoria. Resultado: Se encontraron 6 pacientes con un promedio de edad de 26 años. Cinco pacientes presentaban resonancia magnética al momento del trauma. El intervalo de tiempo promedio entre la resolución de la fractura y la reparación ligamentaria fue de 4 días. El promedio de las escalas evaluadas fue: EVA 0.2, Tegner 4 y Lysholm 87. Conclusión: En pacientes con fractura de miembro inferior de alta energía el compromiso ligamentario no debe subestimarse. Consideramos que la realización de una RM durante la atención inicial del paciente optimiza los tiempos en el diagnóstico y tratamiento de dichas lesiones y conlleva a mejores resultados funcionales al final del tratamiento. Tipo de studio: Serie de casos. Estudio retrospectivo. Nivel de evidencia: IV.

Introduction: Multiligament knee injuries in patients with ipsiletaral inferior limb fractures is a rare entity that can be easily missed. The objective of this work was to analyze a series of patients with multiligament lesion associated with inferior limb fracture. Material and method: A retrospective search was carried out from January 2010 to December 2016 of patients admitted in our hospital with diagnosis of inferior limb fracture associated to multidirectional knee instability. We evaluated the fracture pattern, ligament knee injury, if an initial Magnetic Resonance Imaging (MRI) was performed and the surgical timing. We evaluated pain with Visual Analogue Scale (VAS) and functional outcomes using Tegner and IKDC scores. We included patients with more than one-year postoperative. Results: Six patients were evaluated with an average age of 26 years-old. Five patients presented initial MRI, before the first surgery was performed. The average time between fracture osteosynthesis and ligament reconstruction was 4 days. VAS, Tegner and IKDC mean results were 0.2, 4 and 87 respectively. Conclusion: In patients with high-energy lower limb fractures, ligament compromise must be suspected. We consider that MRI should be performed during the first examination to optimize the diagnosis and treatment of possible associated ligament injuries and to obtain better functional outcomes. Type of study: Retrospective cases serie. Level of evidence: IV.

Colgajo fasciocutáneo sural para la cobertura del tercio distal de pierna y pie / Fasciocutaneous sural flap for soft tissue coverage in the third distal leg, ankle and foot

Introducción: Los traumatismos de alta energía en miembros inferiores se asocian, con frecuencia, a defectos de partes blandas y su reconstrucción puede presentarse como una tarea desafiante. En el extremo distal de la pierna y el pie, los colgajos de perforantes representan la mejor opción de cobertura. El motivo de este trabajo es comunicar el resultado del tratamiento de lesiones de partes blandas de pierna distal, tobillo y talón utilizando exclusivamente el colgajo de perforantes fasciocutáneo sural. Materiales y Métodos: Entre marzo de 2008 y febrero de 2016, en nuestro Hospital, se realizaron 37 colgajos fasciocutáneos surales en 35 pacientes. El criterio de inclusión fue todo paciente con defecto tegumentario en el tercio distal de tibia y talón con exposición ósea, tendinosa o defecto de la almohadilla plantar. La edad promedio fue de 49.6 años y el seguimiento promedio, de 18 meses. Resultados: Se logró la cobertura completa de defecto de tejidos blandos en 29 casos. Se detectaron tres colgajos con necrosis parcial y cinco con necrosis completa; cuatro de estos pacientes tenían antecedentes de enfermedad vascular. El tamaño del defecto fue de 9,6 x 6,7 cm (15 x 9). Conclusiones: Aunque esta serie no es extensa, los resultados coinciden con los publicados. Creemos que este colgajo es una alternativa viable para lesiones distales de pierna y pie, con una baja tasa de complicaciones y de morbilidad en el miembro afectado, y con resultados satisfactorios.

Introduction: High energy injuries in lower limbs are frequently associated with soft tissue defect and soft tissue reconstruction can be a challenge. Perforator flaps are the best option to cover soft tissue defects in the lower leg, ankle and foot. The objective of this paper is to report the results after the use of a distally-based reverse fasciocutaneous sural flap in the reconstruction of soft tissue loss around the distal leg, ankle and foot. Methods: A total of 37 fasciocutaneous pedicled reverse sural flaps were performed in 35 patients between March 2008 and February 2016, in our Hospital. The inclusion criterium was a soft tissue defect of the lower third of the leg, ankle and heel in which bone, tendons and sole are exposed. Average age: 49.6 years and average follow-up: 18 months. Results: Complete soft tissue defect coverage was achieved in 29 cases. Three flaps with partial necrosis and five with complete necrosis were observed; four of these patients had history of vascular disease. Defect size averaged 9.6 x 6.7 cm (15 x 9). Conclusions: Although this series is not extensive, results are consistent with those reported in the literature. We consider that this flap is a valid alternative for lesions involving the distal leg, ankle and foot, with a low rate of complications and morbidity, and satisfactory results.

Gluteal Compartment Syndrome Secondary to Pelvic Trauma.

Gluteal compartment syndrome (GCS) is extremely rare when compared to compartment syndrome in other anatomical regions, such as the forearm or the lower leg. It usually occurs in drug users following prolonged immobilization due to loss of consciousness. Another possible cause is trauma, which is rare and has only few reports in the literature. Physical examination may show tense and swollen buttocks and severe pain caused by passive range of motion. We present the case of a 70-year-old man who developed GCS after prolonged anterior-posterior pelvis compression. The physical examination revealed swelling, scrotal hematoma, and left ankle extension weakness. An unstable pelvic ring injury was diagnosed and the patient was taken to surgery. Measurement of the intracompartmental pressure was measured in the operating room, thereby confirming the diagnosis. Emergent fasciotomy was performed to decompress the three affected compartments. Trauma surgeons must be aware of the possibility of gluteal compartment syndrome in patients who have an acute pelvic trauma with buttock swelling and excessive pain of the gluteal region. Any delay in diagnosis or treatment can be devastating, causing permanent disability, irreversible loss of gluteal muscles, sciatic nerve palsy, kidney failure, or even death.
