Study, Modified Kirschner wires and locking plate internal f
A Study was conducted to evaluate the efficacy of a modified internal fixation method for the treatment of fifth metacarpal neck fracture.

The Kirschner wires and locking plate internal fixation approach was used to treat 12 patients with fifth metacarpal neck fractures of the hands. Gender, age, dominant hand, damaged hand, trauma mechanism, preoperative and postoperative deformity, metacarpophalangeal joint range of motion and grip strength on each side, time to return to work, and follow-up time were all documented and calculated for each patient.

Results:
--The mean follow-up time was 16.8 months, and the angulations of preoperative and postoperative deformity were 40.0±3.7°and 17.6±1.7°, respectively.

--The length of the fifth metacarpals of preoperative and postoperative deformity were 51.5±2.1 mm and 60.0±1.8 mm, respectively.

--At the last follow-up, the range of motion of the fifth metacarpophalangeal joint of the injured side and the contralateral side were 84.3±3.6°and 86.5±2.0°, and the grip strength of the injured side and the contralateral side were 74.8±6.1 LB and 78.6±8.3 LB, respectively, without statistically significant differences.

--QDASH score was 2.0±1.0, and the time of return to work was 6.0±0.7 weeks.

Conclusively, the modified internal fixation method is one of the alternative treatments for the fifth metacarpal neck fracture with good curative effects.
