Abstract PDF: PURPOSE
: We evaluated the results after the lag screw fixations using A.O. 2.0mm mini screws for the unstable multiple spiral metacarpal fractures.
MATERIALS AND METHODS
: thirteen cases of multiple spiral metacarpal fractures were treated with the lag screw fixations using 2.0mm mini cortical screws by the recommended technique of AOASIF. TAM of each digit was measured at the time of last follow up and the result was compared with the contralateral normal digits. We also evaluated the amount of shortening, angulation or rotation at the fracture sites on the last follow-up radiographs.
RESULTS
: Complete radiological unions were obtained in all of the cases. TAM of the operated digits were above 90% compared with those of the contralateral normal digits except 1 case, which had an another fracture and deep laceration at the distal phalanx and proximal interphalangeal joint during the period of follow up. We could not find any shortening, angulation or rotation at the fracture sites on the last follow-up radiographs.
CONCLUSION
: When we consider that the goal of treatment of the metacarpal fracture is to obtain full motion of the digit through the early mobilization after injury, we think that the lag screw fixation using 2.0mm mini screw is a good treatment modality in the cases of unstable multiple spiral metacarpal fractures.
