Proximal Tibial Osteotomy Osteoclasis In Infantile Genu-Varum

Tanta University70 enrolled

Overview

Genu-varum is a common problem encountered in pediatric orthopedic. Correction of pathological deformity is mandatory to ensure normal load transfer through the knee. In this study, the investigators describe a new technique of osteotomy osteoclasis in order to evaluate if it is an effective and reliable method in management of infantile genu varum

Seventy children with 122 legs suffering significant infantile genu-varum were treated by percutaneous osteotomy-osteoclasis technique. The mean age was 46 months. Genu varum was bilateral in 52 children and unilateral in 18 with a mean preoperative proximal medial tibial angle 66.67 ± 2.670. Under general anesthesia, transverse osteotomy osteoclasis was performed below the tibial tuberosity. Follow-up radiograph was done within the first post-operative week and then every two weeks to assess alignment and consolidation.

Outcomes

Primary Outcomes

proximal medial tibial angle

This angle was used for assessment of degree of deformity correction and to follow the presence of under- or over-correction

Time frame: one year

the posterior proximal tibial angle

confirm the absence or presence of any sagittal pro or recurvatum deformities(normal=81±2 degrees)

Time frame: one year

Self-Administered Patient Satisfaction Scale

the investigators asked the parents to rate their satisfaction on a scale from zero to 100 (100 to 75 very satisfied, \<75 to 50 somewhat satisfied, \<50 to 25 somewhat dissatisfied and \<25 dissatisfied).Those who were not satisfied are requested to explain the cause of dissatisfaction.

Time frame: one year
