Short-Term Complications of Relative Femoral Neck Lengthening Combined with Extra-Articular Osteotomies of the Proximal Femur.

Purpose: Relative femoral neck lengthening (RNL) is a newer technique to correct coxa breva and coxa vara to relieve a femoro-acetabular impingement and improve hip abductor function without changing the position of the head on the shaft. Proximal femoral osteotomy (PFO) changes the position of the femoral head relative to the shaft. We studied the short-term complications of procedures that combined RNL with PFO.

Simplified arthroscopic lavage of pediatric septic hip: case series.

Septic arthritis of the pediatric hip is a surgical emergency that requires adequate lavage to decompress the hip, reduce degradative cartilage insult, and prevent coxarthrosis. In this report, we describe a simplified arthroscopic technique that may be performed using a single portal based on fluoroscopy and surface landmarks and without regular use of traction. We present results of a series of patients who underwent the simplified arthroscopic method for the management of pediatric septic hip.

Biomechanical Comparison of Perpendicular Versus Oblique In Situ Screw Fixation of Slipped Capital Femoral Epiphysis.

Background: Percutaneous in situ single screw fixation is the preferred treatment for stable and unstable slipped capital femoral epiphysis (SCFE). The recommended screw placement is in the center of the epiphysis and perpendicular to the physis, which necessitates an anterior starting point for most SCFEs. A recent clinical study has shown good clinical results with a laterally based screw for SCFE, which is oblique to the physis.
