Obesity negatively affects spinal surgery in idiopathic scoliosis.
Are obese patients with idiopathic scoliosis undergoing spinal surgery at higher risk for perioperative complications? This is not clearly understood. One previous study showed a greater preoperative thoracic kyphosis but no increase in perioperative complications. ⋯ Level IV, prognostic study. See Instructions for Authors for a complete description of levels of evidence.

Multicenter StudyChildhood obesity as a risk factor for lateral condyle fractures over supracondylar humerus fractures.
Obese children reportedly have an increased risk of sustaining musculoskeletal injuries compared with their normal-weight peers. Obese children are at greater risk for sustaining fractures of the forearm, particularly from low-energy mechanisms. Furthermore, obesity is a risk factor for sustaining an extremity fracture requiring surgery. However, it is unclear what role obesity plays in fractures about the distal humerus. ⋯ Level II, prognostic study. See the Guidelines for Authors for a complete description of levels of evidence.

Randomized Controlled TrialDoes single use of an autologous transfusion system in TKA reduce the need for allogenic blood?: a prospective randomized trial.
Mechanical autotransfusion systems for washed shed blood (WSB) were introduced to reduce the need for postoperative allogenic blood transfusions (ABTs). Although some authors have postulated decreased requirements for ABT by using autologous retransfusion devices, other trials, mostly evaluating retransfusion devices for unwashed shed blood (USB), verified a small or no benefit in reducing the need for postoperative ABT. Because of these contradictory findings it is still unclear whether autologous retransfusion systems for WSB can reduce transfusion requirements. ⋯ Level II, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Intramedullary nails result in more reoperations than sliding hip screws in two-part intertrochanteric fractures.
Sliding hip screws (SHSs) and intramedullary (IM) nails are well-documented implants for simple two-part intertrochanteric fractures; however, there is no consensus regarding which type of implant is better. ⋯ Level III, therapeutic study. See the Instructions for Authors for a complete description of levels of evidence.

Surgical technique: talar neck osteotomy to lengthen the medial column after a malunited talar neck fracture.
Treatment of malunited talar neck fractures is challenging, and few studies address anatomic reconstruction as an alternative to arthrodesis. We describe a new surgical approach attempting to improve function and avoid development of degenerative changes in the adjacent joints. ⋯ Level IV, therapeutic study. See the Instructions for Authors for a complete description of levels of evidence.
