Clinical Observation of External Fixation Stent Combined with Limited Open Reduction and Kirschner Wire Internal Fixation for Comminuted Distal Radius Fracture

To investigate the clinical effect of external fixation stent combined with limited open reduction and Kirschner wire internal fixation in the treatment of comminuted distal radius fracture. Methods: A total of 40 patients with comminuted distal radius fractures from January 2018 to December 2021 were selected, including 15 males and 25 females. Age 35-74 years old; AO type: C2 type 26 cases, C3 type 14 cases. External fixation stent combined with limited open reduction and internal fixation with Kirschner wire were used for the surgery. Wrist function was evaluated by Dienst score at the last follow-up. Results: In this study, all patients were followed up for 6-12 months after surgery, with an average of 8.5 months. Bone union was achieved in all patients. Complications: 1 case of nail tract infection, 2 cases of Kirschner wire withdrawal, 1 case of traumatic arthritis; According to Dienst score of wrist joint function, 25 cases were excellent, 12 cases were good, and 3 cases were fair. The excellent and good rate of wrist joint function was 92.5% (37/40). Conclusions: External fixation stent combined with limited open reduction and Kirschner wire internal fixation for the treatment of comminted distal radius fracture can effectively fix, avoid the second incision and removal operation, can be performed according to the early stage of functional exercise, postoperative functional recovery of the wrist, providing an effective treatment method for the clinical treatment of this kind of fracture
