Snapping Biceps Femoris Syndrome: A Case Presentation and Review of Current Literature.

Snapping of the biceps femoris tendon over the fibular head is a cause of symptomatic lateral knee pain. We presented the case of an active patient in his mid-20s who had bilateral snapping of his biceps femoris tendon, with no history of trauma. The pathophysiology in our case was thought to be secondary to prominent fibular heads.

The presence of an ossific nucleus does not protect against osteonecrosis after treatment of developmental dysplasia of the hip.

Background: Osteonecrosis (ON) is a major complication after treatment of developmental dysplasia of the hip (DDH). Several studies have explored the absence of the femoral head ossific nucleus at the time of hip reduction as a risk factor for the development of ON, but findings have been inconsistent.

Questions/purposes: We therefore determined the incidence of ON in children who underwent reduction of a dislocated hip in the presence or absence of the ossific nucleus.
