Femoral osteotomy to improve range of motion in residual deformity of perthes disease: A case report.

ABSTRACT: Introduction:The treatment strategies for residual deformity of Perthes disease are not established. Case presentation:This is a case report of a 15-year-old boy. He developed right Perthes disease (lateral pillar classification group B) when he was 10 years old and underwent varus femoral osteotomy of the right side. At 12 years of age, he developed left Perthes disease (lateral pillar classification group B) and underwent varus femoral osteotomy of the left side. Postoperatively, he was treated with partial weight bearing of the left leg with crutches. At 15 years, range of motion (ROM) of his left hip was markedly limited at 30° flexion, 10° abduction, 70° external rotation, and -20° internal rotation, and he was having difficulty maintaining a sitting position. Diagnosis:Stulberg group V was noted on plain radiography. Computed tomography (CT) showed collapse of the load-bearing part of the femoral head on the coronal plane, but the ball-shape was maintained in the posterior femoral head on sagittal and transverse sections. Intervensinos:Valgus-flexion-internal rotation osteotomy was performed to improve ROM. Outcomes:Left hip ROM improved to 90° flexion, 20° abduction, 50° external rotation, and 40° internal rotation immediately after the surgery. He was able to sit 10 months postoperatively but was left with a limp and limited ROM in the left hip at 60° flexion. Chondroplasty was performed during the plate removal surgery at 10 months postoperatively, which improved hip flexion to 100° immediately after the surgery. The patient was left with limited ROM of 60° flexion of the left hip at the final observation. Conclusion:Femoral osteotomy to improve ROM could be an option for residual deformity of Perthes disease.

Project description:Background: Typical sequelae of Perthes disease and Perthes-like deformities comprise a short femoral neck, aspherical femoral head, and greater trochanteric overgrowth. Morscher’s osteotomy aims at restoring the normal extra-articular anatomy, but incapable of restoring a normal head-neck contour with residual impingement. Femoral neck lengthening osteotomy combined with osteochondroplasty through surgical hip dislocation approach was not previously described in the literature. We hypothesized that this technique is capable of near-normal restoration of the proximal femoral anatomy, increasing limb length, restoring abductor power, and simultaneous management of intra-articular chondro-labral disease. Methods: A prospective series of 21 consecutive patients with sequelae of Perthes disease and Perthes-like deformity (Stulberg II and III) were treated by Morscher’s osteotomy through surgical hip dislocation approach. The mean age was 14.9 years (9–30 years) and the mean follow-up was 4.5 years (2–8 years). Results: The mean Harris hip score improved significantly from 66.5 to 89.5 points (p < 0.001), and the mean limb length discrepancy improved from 2.5 to 0.6 cm (p < 0.001). The mean alpha angle improved from 81.8° to 49.5°, the mean neck-shaft angle increased from 117.8° to 129.8°, and the articulo-trochanteric distance has improved from −6.7 to 20.8 mm. Six out of 21 patients required staged periacetabular osteotomy for residual acetabular dysplasia. No cases of chondrolysis or osteonecrosis were identified. Conclusion: Femoral neck lengthening osteotomy through surgical hip dislocation appraoch has proven to be safe and effective for preservation of symptomatic hips with Perthes and Perthes-like deformities and mild to moderate femoral head deformities (Stulberg II and III). A staged periacetabular osteotomy may be required in those patients with significant acetabular dysplasia. Level of evidence: Level IV.
