In appropriately chosen Perthes patients, treatment methods which are based on the principle of containment can be used when there is not an obvious femoral head deformity; whereas in patients with hinge or restricted abduction and joint instability or incongruency, treatment methods can only be partially useful. Common surgical methods which would fall under the category of salvage are namely valgus osteotomy, neck lengthening and trochanteric sliding ostoetomies, shelf arthroplasty, Chiari osteotomy and femoral head reduction. Valgus osteotomy is an outstanding method, generally useful in improving abduction motion, hinge abduction and biomechanics of the hip joint. The success of these methods utilized in relatively late stages of Perthes` disease, in which the pathological development of the joint is irreversible, highly depend on choosing the correct surgical method by better analyzing the clinical findings and morphologic changes in the hip.
