Recovery of elbow motion following pediatric lateral condylar fractures of the humerus.
Temporary elbow stiffness is often seen after a lateral condylar fracture of the distal end of the humerus in children. There are scant scientific data available to assess the expected time frame for return of elbow motion after these injuries. The purpose of this study is to provide a prospective, longitudinal evaluation of elbow motion in a large group of pediatric patients undergoing treatment for a lateral condylar fracture of the distal end of the humerus. ⋯ An initial rapid recovery in elbow motion can be expected after a lateral humeral condylar fracture in a child, with progressive improvements for up to one year after the injury. This recovery is slower if the patient is older, has a longer period of immobilization, and has a more severe injury.

ReviewIn situ fixation for slipped capital femoral epiphysis: perspectives in 2011.
Slipped capital femoral epiphysis is usually treated with in situ fixation to prevent progression of deformity. However, slipped capital femoral epiphysis always is associated with structural risk factors for hip dysfunction in addition to the risk of slip progression. Femoro-acetabular impingement causes some mechanical abnormality in every hip affected by slipped capital femoral epiphysis, even when the slip is mild. ⋯ The treatment of femoro-acetabular impingement in patients who have slipped capital femoral epiphysis is a separate issue from instability of the proximal femoral physis. Femoro-acetabular impingement must be assessed in every hip that is affected by slipped capital femoral epiphysis, even when the deformity is mild. Several treatment options exist for treating femoro-acetabular impingement associated with slipped capital femoral epiphysis.

Cobalt and chromium levels in blood and urine following hip resurfacing arthroplasty with the Conserve Plus implant.
The purpose of the present study was to determine cobalt and chromium ion levels in the blood and urine of patients in whom a modern-generation metal-on-metal hip resurfacing device had been implanted. ⋯ These levels compare favorably with other published ion results for metal-on-metal hip resurfacing and replacement implants. No pseudotumors or other adverse soft-tissue reactions were encountered in our study population. Further research is needed to determine the clinical importance of increased cobalt and chromium ion levels in serum and urine following metal-on-metal hip resurfacing.
