| Objective To investigate the surgical method, effect, complications of intercondylar fracture of femur with cannulated compression screw and Kirschner wire in children. Methods Retrospective analysis was conducted on the surgical efficacy and complications of 11 children with femoral intercondylar fracture in Anhui Provincial Children's Hospital from October 2014 to December 2020. All the 11 cases were treated with open reduction of knee joint, internal fixation of femoral condyle with 1 or 2 cannulated compression screws, percutaneous K-wire fixation of metaphyseal region, and external fixation with cast or brace. The function of knee joint was evaluated after operation according to HSS knee joint scoring standard. Results All 11 cases were followed up for 6~24 months, with an average of (16.52±7.61) months. The Kirschner wires were removed after postoperative reexamination of X-ray showed fracture healing. All 11 cases were healed, and the average time of healing was (12.53±2.42) weeks. The distal femoral epiphyseal bridge was formed in two cases, presenting as genu valgus deformity. Both of them were intercondylar comminuted fracture of femur (C3 type).The flexion of the knee joint was less than 90° in three cases. The curative effect was evaluated after operation, the result was excellent in six cases, good in two cases, fair in one case and poor in two cases. The excellent and good rate was 72.73%. Conclusions Open reduction and fixation with cannulated compression screw and Kirschner wires can achieve satisfactory result in children with intercondylar fracture, but for intercondylar comminuted fracture, it will be accompanied by the formation of metaphyseal bone bridge, and the prognosis is poor. |
