Nguyen Ngoc Hung, Hoang Hai Duc, Le Tuan Anh


Background: Legg-Calve-Perthes disease is a childhood hip disorder that can lead to deformed hips and poor functioning. The purpose of this study is to introduce our technique of incomplete proximal femoral osteotomy for Legg-Calvé-Perthes in children and to describe technical details, postoperative complications, the duration of treatment, and the advantages and disadvantages of this system.

Methods: We analyzed the results of 14 patients (14 hips) who underwent incomplete Proximal Femoral osteotomy for Legg-Calvé-Perthes in our institute since 2008. to 2018. Patients may undergo a long-term examination. Hips are classified with the classification system of Catterall and Herring. Patients were divided into two variants, hip with Catterall II and III in variant 1; Catterall IV is included in variant 2. All hip functions (flexion, internal rotation, external rotation) have been tested. When checking the results using Morse Cllasization. Long-term results were assessed after an average follow-up of 8.2 years.

Results: There was Catterall group: Group II: 2, and Group III: 10, Group IV: 2; Herring group: Herring A: 3, Herring B: 7, Herring C: 4; Stulberg Classification: II: 11, III: 2, IV: 1. Wiberg angle: 17.0° in preoperative surgery and 31.07° in PostOperation with Pvaliated = 0.0007; Morse Cllasization: Good: 5 (35.7%), Fair: 8 (57.2%), Poor: 1 (7.1%). Patients were 6 to 9 years old with all satisfactory results; 100%; Patient was upper 9 years old with satisfactory results: 83.3% and Poor: 16.7%.

Conclusion: Incomplete proximal femoral osteotomy of Legg-Calvé-Perthes disease in children has long-term results for Legg-Calve-Perthes disease was surgical technique is simple and safe.
