Translation and Cross-Cultural Adaptation of the Toronto Extremity Salvage Score (TESS) for Latin American Spanish-Speaking Patients With Limb Sarcoma: Latin American Spanish TESS Adaptation.

This study aims to translate and culturally adapt the Toronto Extremity Salvage Score (TESS) for Latin American Spanish-speaking patients, enhancing the tool's accessibility for evaluating postsurgical functional outcomes in sarcoma patients across Latin America. The TESS questionnaires for lower extremity (LE) and upper extremity (UE) were translated and adapted following international guidelines. The process included forward and backward translation, expert committee review, and pretesting with cognitive interviewing.

Management of Ipsilateral Fractures After Rotationplasty: A Report of 2 Cases and Review of the Literature.

Case: Rotationplasty is a surgical procedure used for restoring functionality after skeletal tumor resection. Multiple complications have been described, including the potential occurrence of fractures. Literature on fracture management after rotationplasty is limited.

Clinical outcomes of total femoral replacement. First Latin American experience.

Introduction: The femur is frequently affected by primary and metastatic bone tumors. In cases with substantial bone loss, Total Femur Replacement (TFR) remains the only viable limb preservation option. This study investigates the clinical outcomes of TFR patients in a Latin American setting, with a minimum 3-year follow-up.

Cross-cultural adaptation and validation of the VISA-A questionnaire for Chilean Spanish-speaking patients.

Background: The purpose of this study is to translate, culturally adapt, and validate the VISA-A questionnaire for Chilean Spanish speakers with Achilles tendinopathy (AT), which has been originally developed for English-speaking population.

Methods: According to the guidelines published by Beaton et al., the questionnaire was translated and culturally adapted to Chilean patients in six steps: initial translation, synthesis of the translation, back translation, expert committee review, test of the pre-final version (cohort n = 35), and development of VISA-A-CH.

[Is instillation of bone marrow stem cells at the time of core decompression useful for osteonecrosis of the femoral head?].

Osteonecrosis of the femoral head leads to degeneration of the head and finally to osteoarthritis of the hip. Decompression is the most widely used treatment, but its effectiveness is limited. It has been proposed instillation of stem cells in addition to decompression, would lead to better results.

Are biologics useful for nail psoriasis?

Apart from involving skin, psoriasis can compromise the nails and adjacent structures. Even though there are multiple therapeutic alternatives, there is great interest in biological therapy, but no consensus on its role exists. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified two systematic reviews including three randomized trials.

Is intramedullary nailing superior to plating in patients with extraarticular fracture of the distal tibia?

Distal tibial metaphyseal fractures are generally produced by high-energy trauma such as car accidents and can cause severe disability due to pain and deformity. In the management of these fractures, there are multiple surgical alternatives, but it is uncertain which the best option is. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified six systematic reviews including three randomized trials.

Does vitamin C prevent the occurrence of complex regional pain syndrome in patients with extremity trauma requiring surgery?

The complex regional pain syndrome is a neuroinflammatory pathology that affects the central and peripheral nervous system, characterized by disproportional pain in relation to the trauma experimented by the patient. It has been proposed that vitamin C could prevent the development of this syndrome in patients with limb trauma and surgery. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified two systematic reviews that indentified four primary studies, including one randomized controlled trial.
