Why the study?
Does nonarticulated hip arthrodiastasis improve clinical and radiographic outcomes in a patient with late-onset Legg-Calvé-Perthes' disease?
Does nonarticulated hip arthrodiastasis improve clinical and radiographic outcomes in a patient with late-onset Legg-Calvé-Perthes' disease?
Nonarticulated hip arthrodiastasis may be a valuable treatment option for complex cases of late-onset Perthes' disease with femoral head extrusion and significant hip stiffness.
May support nonarticulated arthrodiastasis in select late Perthes cases; hypothesis-generating and requires prospective trials before practice change.
Case: We report a case of a 13-year-old boy with late-presenting Legg-Calvé-Perthes’ disease with femoral head extrusion and painful femoro-acetabular impingement. The patient exhibited significant limitations in performing daily activities due to a limping gait requiring elbow crutches. The patient was treated with nonarticulated hip arthrodiastasis. At follow-up after skeletal maturity, the patient demonstrated marked clinical improvement, including a return to sports activity, and radiographs revealed a well-contained and congruent hip joint. Athrodiastasis is a valuable treatment option for complex cases of late-onset Perthes’ disease with femoral head extrusion and significant hip stiffness.
