掌侧锁定钢板治疗桡骨远端Die-punch骨折

Treatment of distal radial Die-punch fracture with volar locking plate

目的评价桡骨远端Die-punch骨折行切开复位掌侧锁定钢板内固定治疗的近期疗效。方法桡骨远端Die-punch骨折13例,年龄47-58岁,均为闭合性损伤。关节面塌陷均超过2mm。采用掌侧入路,关节面复位植骨后用桡骨远端锁定钢板内固定。用DASH调查表进行随访,计算DASH值,测量并分析患侧及自身健侧腕关节活动度。结果 13例的DASH值3.33-11.67(6.54±3.09)分。患侧腕关节活动度在随访时恢复至健侧腕关节的90%以上,但是患侧腕关节活动度较健侧腕关节有明显受损(P<0.05)。结论切开复位掌侧锁定钢板内固定治疗桡骨远端Die-punch骨折的近期疗效显著。

Objective To evaluate the short-term outcome of treating distal radius Die-punch fractures with volar locking plating system. Methods A total of 13 patients,aged from 47 to 58 years old,with closed distal radial fratures of articular stepoff 〉2 mm was treated with volar locking plate osteosynthesis after reduction and bone grafting. The outcomes were evaluated using DASH score. Range of motion（ROM） was measured at the affected wrist and the contralateral side using a goniometer. The results were expressed in absolute values （degrees） and in relation to the unaffected contralateral wrist function （percentage）. Mean follow-up period was 13 months （10-17 months）. Results Averaged DASH score was （6.54± 3.09） points （ranged 3.33-11.67 points）. The affected wrist motion reached more than 90% of the contralateral wrist motion in the follow-up period after surgery. However, wrist ROM remained significantly impaired when compared with the uninjured contralateral wrist. Conclusion Treatment of distal radial Die-punch fracture with volar locking plate osteosynthesis is effective in short-term.
