简要总结
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
详细描述
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.

研究组 & 干预措施
high tibial osteotomy
Under general anesthesia, a one-cm vertical skin incision was done at the medial subcutaneous border of the tibia, one fingerbreadth below the tibial tuberosity. This was confirmed by intra-operative C-arm images. Longitudinal periosteal incision was done with minimal dissection. Incomplete medial transverse osteotomy including both anterior and posterior cortex was performed using drill bit or small thin osteotome.Osteotomy was completed manually by osteoclasis of the lateral cortex to provide postoperative stability by the preserved lateral periosteum. No fibular osteotomy was needed in the present study.

结局指标
主要结局
proximal medial tibial angle
时间窗: one year
This angle was used for assessment of degree of deformity correction and to follow the presence of under- or over-correction
the posterior proximal tibial angle
时间窗: one year
confirm the absence or presence of any sagittal pro or recurvatum deformities(normal=81±2 degrees)
Self-Administered Patient Satisfaction Scale
时间窗: one year
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.
