Effect of a Limited Range of Motion of the Hip Joint on Final Outcome in LCP Disease

Abstract

Purpose: We studied the effect of a limited range of motion (ROM) of the hip joint on the final outcome in LCP disease. Materials and Methods: ROM data obtained during the initial 3 years after diagnosis in unilaterally involved 325 pillar B or C hips (bone age6 years, average age at induction: 7.9 years) were studied. The non-surgical treatment group included: a) no treatment (23), b) brace (113), and c) ROM exercise (70). The surgical treatment group included: a) femoral osteotomy (49), and b) Salter innominate osteotomy (70). We assessed the relationship between the limited ROM and the Stulberg outcome. Results: In the non-surgical treatment group, those patients who had never experienced limited motion below or of flexion, below or of abduction, and below of adduction, were significantly associated with a good Stulberg outcome (p
