[Wrist arthroscopic treatment of Die-punch fracture of distal radius].

OBJECTIVE

To evaluate the effect of open reduction assisted by wrist arthroscopy in the treatment of Diepunch fracture of the distal radius.

METHODS

The clinical data of 50 patients with die punch fracture of distal radius from December 2015 to May 2017 were analyzed retrospectively, including 31 males and 19 females, aged 20 to 45 (34.12±2.56) years. All patients were treated with open reduction and internal fixation of volar plate through volar approach under the assistance of wrist arthroscope. The range of wrist movement and Cooney wrist function score before and after treatment were compared.

RESULTS

All patients were followed up with an average of 18 months. DR scan showed that all fractures healed and no shortening of radial axis. Three cases of incision infection occurred and disappeared after treatment. At 18 months after operation, the range of wrist movement was significantly larger than that before operation (P<0.05) . At 18 months after operation, Cooney wrist function score was higher than that before operation (P<0.05) , excellent in 33 cases, good in 13 cases, fair in 3 cases and poor in 1 case.

CONCLUSION

The treatment of die punch fracture of the distal radius with open reduction assisted by arthroscopy can restore the flatness of the joint surface, promote the recovery of the function of the wrist joint quickly, and has high safety, which is worth popularizing.
