Abstract
Genu valgum is common in pediatric orthopaedics. With the exception of physiological deformities that resolve with observation alone, it may progress, adversely affecting gait and function. Joint laxity and instability may ensue, along with compensatory or confounding deformities. After skeletal maturity, femoral osteotomy is an excellent and proven technique for correcting alignment, restoring the mechanical axis and mitigating the effects of the ground reaction force. The simplicity and cost-effectiveness of this technique make it an attractive alternative to more complex methods of limb deformity correction. This technique is applicable for virtually any pathologic condition, including posttraumatic, metabolic, neuromuscular, idiopathic, or congenital disorders.
The aim of the current study was to determine the efficiency and analyze the results of closing wedge osteotomy operation in adolescents suffering from genu valgum deformity.
The material of this study was 11 patients, age was ranged from 10 to 18 years with mean average of (15.61±1.28) years, 7 female (63.63 %) 4 male (36.36%), and the affection side was 7 bilateral (63.6 %) and 4 unilateral (36.36%). In unilateral cases the left side was affected in 3 limbs (27.2%) and the right side in 1 limb (9.09%), so the total of the limbs were 18 limbs.
They were operated upon to correct the deformity by medial closed wedge of femoral osteotomy, and the fixation was done by medial distal femur locking plate in 2 limbs and proximal tibial plate (T- plate) in 16 limbs, augmented by high above knee cast. All the cases were follow up clinically and radiologically for 18 months period.
Clinical result was determined by using a hospital for special surgery knee-rating score. In the study 11 limbs (60.59%) had excellent clinical results, 6 limbs (33%) had good clinical results and only 1 limb (5.5%) had fair clinical results. The mean of HHS scores were improved (increased) post-operatively with mean 84.15 point.
Radiological result was excellent in 13 limbs (71.5%), 5 limbs (45.5%) had good radiological results. The result was affected significantly by preoperative tibiofemoral angle, degree of postoperative correction.
One patient (9.09%) of them had superficial infection of the surgical wound; the infection was successfully treated with oral antibiotics.
