Abstract
-
PURPOSE: To evaluate the clinical and radiological results of valgus-flexion femoral osteotomy (VFFO) in childhood hip diseases.
MATERIALS AND METHODS
A VFFO was performed in 15 cases of childhood hip disorders with femoral head deformity: LCP disease (8); chronic SCFE (3); AVN after DDH (2), septic hip (1), femur neck fracture (1). Clinically, we evaluated the pre-and postoperative range of motion (ROM), pain, leg length discrepancy, and limping. Radiological evaluation included the neck-shaft angle, status of the osteotomy site and congruency of the femoral head with the acetabulum. Posterior displacement of femoral epiphysis was also evaluated in SCFE.
RESULTS
An average 20.7degrees valgus and 23.0degrees, flexion osteotomy were performed. The average neck-shaft angle changed from 125.9degrees to 146.6degrees, The averaged ROM of the hip joint increased by 16.2degrees (flexion), 17.9degrees (abduction), 16.4degrees (adduction), 26.7degrees (internal rotation), and 15degrees (external rotation). Limitation of motion was greatly improved and the hip joint pain decreased.
CONCLUSION
A VFFO of the proximal femur cannot only eliminate pain by making the best joint congruity, but can also help with the remodeling of a deformed femoral head. Moreover, an increased ROM can make a so-called "Yangban-Dali" possible, which makes daily activity as a Korean more comfortable.
