About

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

Full description

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.

Description:

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.

Treatment:

Procedure: osteotomy
