Comparison of complications and reoperations in AO/OTA 43.C3 pilon fractures treated with conventional ORIF versus minimally invasive hexapod ring fixation.

INTRODUCTION: Controversy exists regarding the optimal management of AO/OTA 43. C3 pilon fractures. Open reduction and internal fixation (ORIF) is the gold standard treatment, but serious soft tissue and infectious complications have been previously reported. Minimally invasive strategies using hexapod ring fixation (HRF) with supplemental limited internal fixation have been used to reduce the incidence of complications. Previous studies have included heterogeneous types of pilon fractures, with non-comminuted injuries being more likely to be treated with ORIF and complex fractures receiving HRF treatment. To our knowledge, no studies have compared the complications and reoperation rates between ORIF and HRF exclusively for C3 fractures. METHODS: Retrospective study comparing 53 patients treated for AO/OTA 43.C3 pilon fracture with ORIF or HRF in a trauma level I center with at least a two-year follow-up. Patients treated between January 2015 and January 2019 received ORIF and those treated between January 2019 and January 2021 received HRF. Complications were divided into two groups: minor (superficial infection and malalignment) and major (non-union, deep infection, and amputation). Reoperations, prevalence of ankle osteoarthritis, and requirement for ankle arthrodesis/total ankle replacement were registered. RESULTS: We included 30 and 23 patients in the ORIF and HRF groups, respectively. The overall complication rate was similar in both groups, with 50% and 56,5% of the patients having complications in the ORIF and HRF groups, respectively (p:0,63). Minor complications were significantly more prevalent in the HRF group (p<0,001) whilst the ORIF group had a significantly higher rate of major complications (p<0,01). Superficial infections were highly prevalent in the HRF group (47,8%), as they were related to half-pin or K-wire infections. Deep infection was present only in the ORIF group, with 20% of the patients developing this major complication (p:0,03). Non-union rate, reoperations, ankle osteoarthritis, and the need for arthrodesis or ankle replacement showed no significant differences. CONCLUSION: In AO/OTA 43.C3 fractures, HRF is safe and effective, achieving high union rates with a significantly lower rate of major complications compared to ORIF. According to our results, ORIF should be used cautiously for these types of fractures, considering the increased risk of deep infection.

Treatment of Severe Rigid Posttraumatic Equinus Deformity With Gradual Deformity Correction and Arthroscopic Ankle Arthrodesis.

BACKGROUND: Posttraumatic ankle equinus is associated with rigid deformity, poor skin condition, and multiple prior surgeries. Open acute correction has been described using osteotomies, talectomy, and arthrodesis, but concerns exist about skin complications, neurologic alterations, secondary limb discrepancy, and bone loss. Gradual correction using a multiplanar ring fixator and arthroscopic ankle arthrodesis (AAA) may decrease these complications. METHODS: We retrospectively reviewed patients undergoing correction of posttraumatic rigid equinus with at least 1 year of follow-up after frame removal. The procedure consisted of percutaneous Achilles lengthening, gradual equinus correction using a multiplanar ring fixator, and AAA retaining the fixator in compression with screw augmentation. Frame removal depended on signs of union on the computed tomography scan. Visual analog scale (VAS) and Foot Function Index (FFI) scores were assessed as well as preoperative and postoperative x-rays. Complications were noted throughout the follow-up period. RESULTS: Five patients were treated with a mean age of 35 years and mean follow-up of 31 months. Deformities were gradually corrected into a plantigrade foot over an average duration of 6 weeks. Union was achieved in all patients with a mean time of an additional 25 weeks, for a mean total frame time of 31 weeks. The mean preoperative tibiotalar angle was 151 degrees and was corrected to 115 degrees. FFI score improved from a mean of 87 to 24 and VAS from 8 to 2. CONCLUSION: Posttraumatic rigid equinus can be treated effectively using gradual correction followed by integrated AAA in a safe and reproducible manner. Patients in this series had excellent functional, radiological, and satisfaction results. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Expectativas y aprensiones de los pacientes sometidos a cirugía de reconstrucción de ligamento cruzado anterior de rodilla / Expectations and concerns of patients undergoing anterior cruciate ligament reconstruction surgery

INTRODUCCIÓN: La lesión del ligamento cruzado anterior (LCA) es una afección frecuente cuyo manejo quirúrgico genera incertidumbre en el paciente sobre su retorno a la actividad. Las expectativas previas al procedimiento influyen en su percepción del éxito del tratamiento, la aparición de complicaciones y en el resultado final, comprometiendo la satisfacción en el postoperatorio. OBJETIVO: Determinar las preocupaciones y expectativas de los pacientes sometidos a cirugía de reconstrucción de LCA. MÉTODO: Estudio prospectivo observacional realizado a través de encuestas a pacientes con lesión del LCA que serían sometidos a una cirugía de reconstrucción. Las variables evaluadas fueron edad, mecanismo de lesión, práctica de actividad deportiva, información previa acerca de la intervención quirúrgica y las preocupaciones y expectativas sobre el procedimiento. RESULTADOS: Cincuenta pacientes fueron encuestados, 38 hombres y 12 mujeres, con edad promedio de 30 años. Los mecanismos de lesión más frecuentes correspondieron a accidentes deportivos de fútbol y esquí. El 96% de los encuestados practicaba algún deporte de forma regular (promedio 5h semanales) previo a la intervención quirúrgica. El 90% de los pacientes investigaron sobre la cirugía de reconstrucción de LCA. Las principales preocupaciones preoperatorias correspondieron al tiempo de recuperación (40%) y a la posibilidad de reintegrarse en la práctica deportiva (38%). Las expectativas se concentraron en lograr un reintegro deportivo precoz (54%) y la presencia de dolor postoperatorio (40%). CONCLUSIÓN: Los pacientes sometidos a reconstrucción de LCA presentan preocupaciones principalmente respecto al tiempo de recuperación postoperatorio y sus expectativas se centran en el logro de un reintegro deportivo precoz.

INTRODUCTION: Anterior cruciate ligament (ACL) injury is a common condition and its surgical treatment causes uncertainty in patients about their return to activity. The expectations prior to the procedure influence their perception of treatment success, development of complications, and final results, and can have an impact on post-surgical patient satisfaction. OBJETIVE: To determine the concerns and expectations of patients undergoing ACL reconstruction surgery. METHOD: Prospective observational study, in which questionnaires were completed by patients with ACL injury that would undergo reconstructive surgery. The evaluated variables were age, mechanism of injury, sports practice, prior information about the surgery and concerns and expectations about the procedure. RESULTS: A total of 50 patients completed the questionnaire, of whom 38 were men and 12 women with a mean age of 30 years. The most common injury mechanisms were when practicing football and skiing. Almost all (96%) of respondents played sports regularly (average 5hours a week) before the surgery. A total of 90% of patients had enquired about ACL reconstruction surgery. The main pre-operative concerns were recovery time (40%) and the possibility of reinstatement of sports (38%). Expectations are focused on achieving an early sports recovery (54%) and the presence of postoperative pain (40%). CONCLUSION: Patients undergoing ACL reconstruction have concerns primarily as regards post-surgical recovery time and expectations are focused on achieving an early reinstatement of sports.
