Abstract:

BACKGROUND: There are a lot of methods for the treatment of Bennett fractures; however, there is no uniform therapeutic regimen and evaluation criterion for the more prone Buechler zone 2 Bennett fractures.
OBJECTIVE: To compare the function recovery of open reduction screw fixation and percutaneous pinning for the treatment of Buechler zone 2 Bennett fractures.
METHODS: Patients with Buechler zone 2 Bennett fractures were randomly divided into the screw group and the K-wire group; the patients in the screw group were treated by open reduction screw fixation and the patients in the K-wire group were purposed by close reduction percutaneous fixation. The disabilities of the arm, shoulder and hand score were used to evaluate the function recovery.
RESULTS AND CONCLUSION: The disabilities of the arm, shoulder and hand score of the screw group were lower than those of the K-wire group after fixation, 1-year follow-up and 2-year follow-up (P < 0.05). The functional recovery of open reduction screw fixation is better than percutaneous K-wire fixation for Buechler zone 2 Bennett fractures.
