Mini-plate versus Kirschner wire internal fixation for treatment of metacarpal and phalangeal fractures.

OBJECTIVE

To conduct a meta-analysis to show the associations of perioperative and postoperative outcomes of mini-plate internal fixation (MPIF) versus Kirschner wire internal fixation (KWIF) for treating metacarpal and phalangeal fractures.

METHODS

A literature search was performed in PubMed, Web of Science, Cochrane Library, and Embase from the earliest date of data collection to April 2018. Studies that compared perioperative and postoperative outcomes of MPIF with those of KWIF in patients with metacarpal and phalangeal fractures were included.

RESULTS

Twenty-six articles met the inclusion and exclusion criteria (n = 2029 patients; 1042 with MPIF and 987 with KWIF). MPIF was related to a greater increase in length of surgery, hospital days, excellent and good rate of outcome, short-form health survey-36 score, and flexion and extension range compared with KWIF. MPIF was related to a greater decrease in intraoperative blood loss, finger visual analog scale score, functional exercise time, fracture healing time, incidence of complications, and postoperative infection rate compared with KWIF.

CONCLUSIONS

Patients with MPIF have sufficient pressure and strength, and MPIF promotes successful joint fusion and reduces complications of the operation. MPIF is ideal for reduction and stability of patients with metacarpal and phalangeal fractures.
