    Abstract:
    OBJECTIVE: To observe the effectiveness of digital customized plate in the treatment of complex limb fracture. METHODS: Between January 2012 and May 2013, CT raw data of complex limb fracture were used to establish the fracture three-dimensional simulation model after reduction, and a customized personalized anatomic plate was designed and used for internal fixation after open reduction in 42 cases. There were 22 males and 20 females, aged 16-53 years (average, 37.4 years). The causes of injury were traffic accident in 21 cases, falling from height in 18 cases, crush by heavy objects in 3 cases, including 26 cases of fresh closed fracture and 16 cases of open fracture (9 cases of type I and 7 cases of type II according to Gustilo classification). According to AO classification, there were 15 cases of humerus comminuted fracture, 4 cases of radial comminuted fracture, 8 cases of femoral comminuted fracture, and 15 cases of tibia comminuted fracture. The interval of injury and operation was 6-28 days (mean, 10 days). RESULTS: Reduction and internal fixation of fracture were successfully performed on 42 patients. The length and position of digital customized plate, direction and length of screw implant, number of screw were basically identical with preoperative design. The operation time was 35-120 minutes (mean, 70 minutes); the blood loss volume was 30-500 mL (mean, 180 mL); and X ray fluoroscopy frequency was 2-6 times (mean, 3 times). Superficial infection occurred in 2 cases, and was cured after dressing change; primary healing of incision was obtained in the other patients. Forty-two cases were followed up 6-24 months with an average of 11.5 months. The fracture healing time was 8-19 weeks (mean, 14 weeks) in 41 cases; delayed union occurred in 1 case at 44 weeks after operation. The fracture anatomical reduction was achieved in 19 cases, malunion in 3 cases, and functional reduction in the other patients. At last follow-up, no plate and screw loosening and breakage was observed. CONCLUSION: Digital customized plate in treatment of complex fractures of limbs, especially for the multiple comminuted fracture of long bones of the limbs has the advantages of convenient operation, less trauma, fewer complications, and good effectiveness.
