Abstract:

BACKGROUND: Studies have suggested that conservative treatment of distal radius fractures has a significant impact on wrist functional recovery, clinical treatment often focus on the anatomical reduction of the articular surface of the distal radius, restore palmar inclination and ulnar inclination, thus benefit to the functional recovery of the wrist.
OBJECTIVE: To evaluate the recuperative effects of wrist in distal radius comminuted fracture with three fixation methods, and its advantages and disadvantages.
METHODS: Eighty-eight patients of distal radius comminuted fractures were selected, 35 patients underwent closed reduction and plaster external fixation, 28 patients underwent external fixing frame, and 25 patients underwent open reduction and plate fixation. The healing time, wrist bone anatomical structure and functional recovery were retrospectively analyzed.
RESULTS AND CONCLUSION: All the patients were treated for union. The healing time of fracture was average (11.2±2.8) weeks in plaster fixation group, the time was average (11.8±3.0) weeks in external fixing frame group, and average (10.8±2.6) weeks in plate fixation group. There was no significant difference of fracture healing time compared with plaster fixation group (P > 0.05). The X-ray film at 6 months after operation showed the palmar inclination and ulnar deviation of distal radius in the plate fixation group were higher than those in the external fixing frame group and plaster fixation group, and the differences were significant (P < 0.05). The excellent and good rate of wrist function was evaluated with the modified Gartland and Werley standards. The excellent and good rate of plaster fixation group was 54%, the external fixing frame group was 75%, and the plate fixator group was 92%. There were significant differences of the excellent and good rate of distal radius compared with plate fixation group (P < 0.05). The results showed that there was no significant difference of the healing time of distal radialis comminuted fracture among three methods of fixation. The bone anatomical structure of distal radialis fracture was effectively maintained with plate fixation, and the recovery of wrist joint function with plate internal fixation was better than external fixing frame or plaster fixation.
