title: Arthrodiatasis for chondrolysis with hinge abduction: a case report.
abstract: A 13-year-old boy with bilateral chronic slipped capital femoral epiphysis was referred to the Nagoya University Hospital. Chondrolysis occurred on the left side 3 months after a subcapital wedge osteotomy and a concavity of the femoral head appeared, which formed hinge abduction. Increase of the joint space and resolution of the hinge were achieved by arthrodiatasis. As arthrodiatasis can resolve hinge abduction by distraction and reduce mechanical stress, it may be taken into consideration as an option for diseases with hinge abduction.
