[Wrist arthroscopy assisted open reduction and bone graft through bone window internal fixation for the treatment of distal radius Die-punch fractures].

OBJECTIVE

To explore clinical effect of wrist arthroscopy assisted open reduction and bone graft through bone window internal fixation in treating distal radius Die-punch fractures.

METHODS

From March 2016 to March 2017, 12 patients with distal radius Die-punch fractures were treated by wrist arthroscopy assisted open reduction and bone graft through bone window internal fixation, including 8 males and 4 females aged from 20 to 42 years old. Preopeative X-ray and CT were used to diagnosed as compress and collapse Die-punch fractures. Joint activity was observed, postoperative VAS score and Cooney wrist score were used to evaluate pain and wrist function at 12 months.

RESULTS

No surgical complications occurred. All patients were followed up from 10 to 13 months with an average of 12.1 months. VAS score was for 0 to 3 points at 12 months after operation. Palmer tilt angle was for 5° to 15°, ulnar drift angle was for 14° to 23°, wrist flexion motion ranged from 123° to 168°, and forearm rotation motion ranged from 115° to 170°. Postoperative Cooney wrist score at 12 months ranged from 70 to 95 points, 10 patients got excellent results, 1 good, and 1 moderate.

CONCLUSIONS

Wrist arthroscopy assisted open reduction and bone graft through bone window internal fixation in treating distal radius Die-punch fractures has advantages of good recovery of wrist function, reduce pain symptom, and could receive satisfied clinical effects.
