Clinical efficacy analysis of trans-articular plate combined with Kirschner wire for treatment of the fifth carpometacarpal joint fracture and dislocation

Objective To evaluate the clinical efficacy of trans-articular plate combined with Kirschner wire for treatment of the fifth carpometacarpal joint fracture and dislocation. Methods From July 2016 to June 2018, 10 cases of the fifth carpometacarpal joint fracture and dislocation were treated with trans-articular plate combined with Kirschner wire. The pain, range of motion, function and grip strength of the wrist were followed up after operation, and the effect was evaluated by Cooney wrist function score. Results The postoperative follow-up period ranged from 10 to 33 months, with an average of 20.3 months. There were no complications such as fracture of internal fixation, nonunion and malunion of fracture. At the last follow-up, the flexion and extension range of the affected wrist was (116.2±11.9)° which was 89.6% of that of the healthy side; the grip strength of the affected side was (85.2±19.6) lb which was 91.1% of that of the healthy side. There were 7 cases without pain and 3 cases with occasional pain. All patients returned to normal work. According to Cooney's wrist function score, 2 cases were excellent and 8 cases were good. Conclusion The clinical efficacy of trans-articular plate combined with Kirschner wire for treatment of the fifth carpometacarpal joint fracture and dislocation is satisfactory and worthy of clinical application.
