Three out of 480 hips with Legg-Calve-Perthes disease have been found to have intraarticular osteochondroma-like lesions of the femoral neck. In all three cases, the osteochondroma unexpectedly diminished in size during the last phase of reossification and, therefore, did not require surgical excision. The occurrence of osteochondroma of the femoral neck with Perthes disease is rare, and resolution has not been previously reported.
在480例患有Legg-Calve-Perthes病的髋关节中，发现有3例存在股骨颈关节内骨软骨瘤样病变。在所有3例病例中，骨软骨瘤在再骨化的最后阶段意外缩小，因此无需手术切除。患有Perthes病的股骨颈骨软骨瘤的发生很罕见，且此前尚未有消退的报道。
