Summary
Multiple cartilaginous exostosis commonly causes lower extremity deformities, particularly genu valgum and ankle valgus. Surgical intervention for hip deformities is not recommended during growth, but knee and ankle issues require early detection.
Area of Science:
- Orthopedics
- Radiology
- Pediatric Orthopedics
Background:
- Multiple cartilaginous exostosis (MCE) is a benign skeletal disorder characterized by multiple osteochondromas.
- Lower extremity deformities are a common complication of MCE, impacting joint alignment and function.
Purpose of the Study:
- To radiologically evaluate the types and progression of lower extremity deformities in patients with MCE.
- To assess the effectiveness of surgical interventions and provide recommendations for management.
Main Methods:
- Radiological examination of lower extremities in 26 patients with MCE.
- Longitudinal follow-up ranging from 3 to 33 years (mean 10.3 years).
- Analysis of femoral neck-shaft angle (FNA), femorotibial angle, and ankle mortise angle.
Main Results:
- Twenty-four patients exhibited joint deformities.
- Common deformities included increased FNA (14 patients), genu valgum (11 patients), and ankle valgus (15 patients).
- Deformities, especially genu valgum and ankle valgus, showed progression with growth; surgical correction in two patients relapsed.
Conclusions:
- Hip deformities in MCE generally do not require surgical treatment during the growth period.
- Progressive knee and ankle deformities warrant early detection and careful consideration for surgical indications.
- Current surgical approaches may not provide lasting correction for significant lower extremity deformities in MCE.
