Validation of the Brazilian version of the musculoskeletal tumor society rating scale for lower extremity bone sarcoma.
The Musculoskeletal Tumor Society (MSTS) rating scale is an English-language instrument used worldwide to assess functional evaluation of patients with musculoskeletal cancer. Despite its use in several studies in English-speaking countries, its validity for assessing patients in other languages is unknown. The translation and validation of widely used scales can facilitate the comparison across international patient samples. ⋯ The Brazilian version of the MSTS rating scale was translated and validated. It is a reliable tool to assess functional outcome in patients with lower extremity bone sarcomas. It can be used for functional evaluation of Brazilian patients and crosscultural comparisons.

The value of valgus stress radiographs in the workup for medial unicompartmental arthritis.
High tibial osteotomy and unicompartmental knee arthroplasty are surgical treatment options for unicompartmental knee arthritis; these procedures are indicated for patients who do not have severe arthritis in the lateral compartment. Valgus stress radiographs sometimes are used to make this evaluation, but this test has not been critically evaluated. ⋯ Valgus stress radiographs provided no added benefit to the radiographic assessment of the lateral compartment cartilage and regarding the correctability of the varus deformity.

ReviewThe initial trauma center fluid management of penetrating injury: a systematic review.
Damage-control resuscitation is the prevailing trauma resuscitation technique that emphasizes early and aggressive transfusion with balanced ratios of red blood cells (RBCs), plasma (FFP), and platelets (Plt) while minimizing crystalloid resuscitation, which is a departure from Advanced Trauma Life Support (ATLS) guidelines. It is unclear whether the newer approach is superior to the approach recommended by ATLS. ⋯ Patients with penetrating injuries who require massive transfusion should be transfused early using balanced ratios of RBC, FFP, and Plt. Randomized, controlled trials are needed to determine optimal ratios for transfusion.

Comparative StudyRetrograde versus antegrade intramedullary nailing of gunshot diaphyseal femur fractures.
The use of retrograde nailing for gunshot wound femur fractures is controversial due to concerns of knee sepsis after this procedure since the knee is entered to introduce the nail into the canal. ⋯ With the numbers available, immediate retrograde nailing appears as safe and effective as antegrade nailing for gunshot femur fractures. Immediate retrograde nailing is as safe as antegrade nailing for gunshot femur fractures.

Tracked ultrasound snapshots in percutaneous pedicle screw placement navigation: a feasibility study.
Computerized navigation improves the accuracy of minimally invasive pedicle screw placement during spine surgery. Such navigation, however, exposes both the patient and the staff to radiation during surgery. To avoid intraoperative exposure to radiation, tracked ultrasound snapshots-ultrasound image frames coupled with corresponding spatial positions-could be used to map preoperatively defined screw plans into the intraoperative coordinate frame. The feasibility of such an approach, however, has not yet been investigated. ⋯ Tracked ultrasound may allow accurate computer-navigated pedicle screw placement while avoiding ionizing radiation in the operating room; however, further studies that compare this approach with other navigation techniques are needed to confirm the practical use of this new approach.
