OBJECTIVETo study clinical efficacy of manual reduction and traction fixation for the treatment of metacarpal neck fracture under ultrasound-guided.

METHODSFrom April 2013 to August 2016, 30 patients with metacarpal neck fractures were treated with manual reduction and traction fixation under ultrasound-guided, including 26 males and 4 females aged from 14 to 56 years old with an average of (25.6±1.6) years old, the courses of diseases ranged from 7 h to 5 d with an average of (2.7±0.6) d. Twenty patients were the fifth metacarpal neck fracture, 7 patients were the 4th and 5th metacarpal neck fractures, 3 patients were the second metacarpal neck fracture. Fracture healing, angle of bilateral head shaft angle and active range of metacarpophalangeal joints was measured, and DASH score was applied to evaluate function.

RESULTSTwenty-seven patients were followed up from 6 to 11 months with an average of(7.2±0.8) months. Fracture were healed from 5 to 8 weeks with an average of (5.6±0.4) weeks. The affected shaft angle was (15.1±1.8)°, and health head shaft angle was (13.5±2.8)°, while there was no significant difference (=1.54, >0.05). The affected range motion of metacarpophalangealjoint was(86.3±2.6)°, health active range motion of metacarpophalangeal joint was(91.8±1.6)°, and no significant difference between both side (=1.16, >0.05). DASH score was 4.3±1.5 at 7 months after operation.

CONCLUSIONSManual reduction and traction fixation for the treatment of metacarpal neck fracture under ultrasound-guided could dynamic observe fracture position in time, high patients' acceptability and is a feasible method for the treatment of metacarpal neck fracture.
