METHODS: Twenty patients treated with a volar locking plate were evaluated. The active range of motion and grip strength were assessed at four weeks, six weeks, three months, six months and one year after surgery.
RESULTS: The ratio of the range of motion in pronation and supination recovered significantly earlier than for any other directions within six months after surgery (p = 0.0205), however, the ratio of the range of motion among the six directions was not significantly different at one year after surgery (p = 0.0823). The recovery of the range of motion in flexion was 96.8% compared with the contralateral wrist at one year after surgery, and it was not significantly lower than that in extension, radial deviation or ulnar deviation (97.8%, 93.5%, 94.4%, respectively). The grip strength of dominant hand recovered from 50% after four weeks to 66% after six weeks, 83% after three months, 91% after six months and 106% at the examination performed after one year compared with the uninjured non-dominant hand. The grip strength of non-dominant hand recovered from 52% after four weeks to 59% after six weeks, 79% after three months, 84% after six months and 94% at the examination performed after one year compared with the uninjured dominant hand. The mean DASH score was 5.3.
CONCLUSIONS: The range of motion in flexion can achieve similar improvement to that in the other directions by obtaining the appropriate postoperative parameters. The optimal postoperative radiographic parameters were thus identified to be essential for successfully obtaining a recovery of the wrist function for unstable distal radius fractures.
BACKGROUND: The purpose of our present study was to examine the recovery of the postoperative wrist function, and to compare the range of motion among each direction ofthe wrist joint during the same time periods after surgery for distal radius fractures.
