Abstract:
OBJECTIVE:To explore the clinical efficacy of external micro-locking plate combined with closed reduction in the treatment of fifth metatarsal comminuted fracture with severe soft tissue injury.
METHODS:From January 2018 to December 2019, 13 patients received micro-locking plate combined with closed reduction treatment due to the fifth metatarsal comminuted fracture with severe soft tissue injury. There were 11 males and 2 females patients, ranging in age from 21 to 69 years. According to the fracture AO fracture classification, 9 cases belonged to type 87(S)-C2.2 and 4 cases belonged to type 87(S)-C2.1. The fifth metatarsal cuneiform articular surface was not involved, and all of them were comminuted fractures of the fifth metatarsal shaft. All soft tissues were damaged to varying degrees. Three patients got small defect of skin and soft tissue, and they were treated with debridement and suture after one-stage emergency surgery. The fracture healing and complications were observed, and the clinical efficacy was evaluated according to the midfoot function score of American Orthopaedic Foot & Ankle Society (AOFAS) at the latest follow-up.
RESULTS:All patients were followed up, and the duration ranged from 3 to 12 months. One patient had delayed union. One patient had local skin necrosis and was treated with second-stage skin grafting to repair the wound surface. No external screw breakage or infection was reported, the skin soft tissue healed satisfactorily and reached bony union, with the union time ranging from 8 to 19 weeks. The postoperative functional recovery was rated according to the midfoot score of AOFAS, the score ranged from 49 to 98, and 7 patients got an excellent result, 4 good, 1 fair and 1 poor.
CONCLUSION:The external micro-locking plate combined with closed reduction in the treatment of fifth metatarsal comminuted fracture with severe soft tissue injury has the advantages of simple operation, good stability and low infection rate, which is helpful to the repair of soft issue injury, and the fixation can be removed early in outpatient clinic. To sum up, this surgical procedure is suitable for patients with severe soft tissue injury and comminuted fracture to avoid periosteum stripping. The space occupying is smaller than the micro-external fixator, which is convenient for patients with early functional exercise.
