Comparing hand strength and quality life of locking plate versus intramedullary k wire for transverse midshaft metacarpal fractures

---

Abstract

Aim: In the scientific literature there are no papers that clarify which method of surgical fixation in transverse metacarpal fractures has the best functional outcomes. The aim of this study was to compare the hand strength obtained using two different methods in the treatment of these fractures.

Methods: A total of 52 patients who presented a transverse metacarpal fracture were enrolled. They were divided in two groups: 26 patients treated with K-wire (IMN) and 26 patients treated with plate and screws (PW). The evaluation criteria were: fracture healing time, performed force testing collected ultimate tensile strength and grip, the Disability Arm Shoulder and Hand (DASH) score, and the range of motion of the hand.

Results: In both groups obtained results were comparable in terms of full hand function, healing and total range of motion and DASH.

Results: in group K were slightly better than group PW in terms of strength and grip pain within 3 months from osteosynthesis.

Conclusion: Neither of the two techniques, either in the literature or in biomechanical studies, shows to have superior functional outcomes for fixation of transverse metacarpal fractures. Since the K-wire is cheaper and has no intrinsic complications as compared with plating (such as scar and tendon irritation), fixation with the latter is preferable to the plate in the treatment of these fractures in non-expert hands.
