Open reduction and bone graft with internal fixation through bone window for the treatment of type B4 distal radius fractures / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To explore clinical effect of open reduction and bone graft with internal fixation through bone window for the treatment of type B4 distal radius fractures.</p><p><b>METHODS</b>From January 2015 to June 2016, 13 patients with type B4 distal radius fractures treated with bone graft with internal fixation through bone window, including 9 males and 4 females aged from 18 to 36 years old with an average of 26.3 years old. Fractures were classified to type B4 according to AO/OTA classification. Fracture healing and postoperative complication were observed, VAS score was used to evaluate pain, and Cooney wrist scoring was applied to evaluate recovery of function.</p><p><b>RESULTS</b>All patients were followed up from 10 to 14 months with an average of 12.4 months. Fracture healed from 4 to 6months with an average of 5.2 months. According to Cooney wrist scoring, 10 got excellent results, 2 good and 1 moderate. VAS score was 1.0±1.1, grip strength of contralateral ratio was (88.2±2.7)%, palmer tilt angle was (12.2±3.8)°, ulnar drift angle was (19.3±5.4)°, wrist flexion mobility was (118.1±2.3)°, forearm rotation motion was (158.0±13.0)°. No osteoarthritis occurred and symptoms occurred during follow-up.</p><p><b>CONCLUSIONS</b>Open reduction and bone graft with internal fixation through bone window for the treatment of type B4 distal radius fractures, which has advantages of satisfied clinical effects, less complications, is one of the effective method for type B4 distal radius fractures.</p>
