Abstract
Background: Efficient surgical repair of coxa vara can be challenging, including thorough clinical and radiological evaluation, preoperative strategy, implant choice, and attentive surgical intervention.
Objectives: To compare the outcome of surgical correction of developmental coxa vara with traditional plate versus monolateral external fixator.
Methods: This study included 20 children with developmental coxa vara ,the mean age at initial surgery was 10.1 +20 122 215 4371 (range 7 to 11 years).. The studied children were randomized and divided according to surgical management into; group (A) with monolateral external fixator and group (B) with traditional plate.
Hilgenreiner-epiphyseal angle (HEA) and the femoral neck-shaft angle (FNSA) were measured before surgery and at latest follow-up.
Results: After treatment, the mean FNSA in fixator group was significantly increased to 129.10± 3.35 degrees and in plate group significantly increased to 125.40± 3.17 degrees. Postoperatively, we recorded a mean ATD of 11.70± 3.20 mm, with significant changes (p=0.005) in fixator group and plate group showed a mean ATD of 8.70± 2.15 mm, with significant changes (p=0.005). Postoperative FNSA and ATD improved significantly in fixator group than plate group (p=0.021 & 0.024, respectively). There was a significant decrease in HE angles postoperative compared to preoperative in both groups (p=0.005). Also, postoperative HE angles improved significantly in fixator group than plate group (p=0.044).
Conclusion: Surgical correction of coxa vara by monolateral external fixator have a higher significant outcome than plate with easily reproducible, efficient in deformity correction and no evidence of deformity recurrence.
