When is osteotomy recommended for Perthes disease?

Perthes disease affects the blood supply to the rounded head of the thigh bone. During healing, the surgeon may need to keep that head deeply positioned inside the hip socket so it can remodel with a useful shape. An osteotomy changes the angle of a bone to improve this fit. The choice depends on the child’s age, hip shape, range of movement, stage of the disease, and whether the joint remains contained.

Arrange assessment with a paediatric orthopaedic team. The evaluation may include an examination of hip movement and imaging taken over time. Until advice is given, follow activity limits, prescribed exercises, and pain-relief instructions. Do not force painful stretches or resume impact sports without clearance.

Seek prompt medical advice if pain or limping suddenly worsens, the child cannot bear weight, the hip becomes markedly stiff, or fever accompanies joint pain. These features need assessment because they may indicate a problem that is separate from the usual course of Perthes disease.

Ask whether the hip is contained, what the latest images show, how much movement is available, and which surgical or non-surgical options fit the child’s stage of healing. Clarify the expected hospital stay, rehabilitation plan, weight-bearing limits, and signs that should trigger an urgent call.
