ARTICLE HIGHLIGHTS
Research background

Legg-Calvé-Perthes disease is a condition that affects the hip joint, most commonly in children between the ages of 4 and 10. In this disease, the blood supply to femoral head. The treatment of late-stage Perthes disease remains controversial, and there is debate about the most effective techniques for managing symptoms and improving long-term outcomes.

Research motivation

The motivation for this study was to contribute to the ongoing debate about the most effective treatment approaches for late-stage Perthes disease, and to evaluate the potential benefits of subtrochanteric valgus osteotomy in improving symptoms and long-term outcomes.

Research objectives

The objective of this study was to evaluate the outcomes of subtrochanteric valgus osteotomy in patients with late-stage Perthes disease.

Research methods

The study included 36 symptomatic patients with late-stage Perthes disease who underwent subtrochanteric valgus osteotomy between 2000 and 2007. The patients were aged 8 or older at the time of surgery, in the post-fragmentation stage of the disease, and experiencing pain, limited range of motion, Trendelenburg gait, and/or abductor weakness.

Research results

The results of the study showed that subtrochanteric valgus osteotomy significantly improved hip function and range of motion in patients with late-stage Perthes disease.

Research conclusions

The study concluded that subtrochanteric valgus osteotomy can be an effective treatment option for relieving symptoms and improving hip function and range of motion in patients with late-stage Perthes disease. The results of the study suggest that this surgical technique can be a valuable addition to the range of treatment options available for this condition.

Research perspectives

The study provides important insights into the potential benefits of subtrochanteric valgus osteotomy for patients with late-stage Perthes disease. However, further research is needed to confirm the findings of this study and to evaluate the long-term outcomes of this treatment approach.
