Abstract

Objectives: This study aimed to evaluate the prognostic factors of reoperation after plate fixation for midshaft clavicle fracture and compare outcomes of dynamic compression plates (DCP) and pre-contoured locking plates. Design: Retrospective comparative study. Setting: Level I trauma center. Patients/participants: We recruited 274 consecutive patients who underwent plate fixation for midshaft clavicle fracture from 2007 to 2017 and completed at least 1 year of follow-up. Intervention: 235 patients underwent surgery with DCP, while 39 patients were treated with locking plate. Main outcome measurements: We reviewed the possible variables of secondary surgeries, and documented complications from the medical records. Patients with a DCP or locking plate were further divided for outcome comparisons. Results: 150 (54.7%) patients underwent reoperation after the initial surgery, and plate removal represented the major etiology. On multivariate analysis, superficial wound infection and prominent implant were identified as significant risk factors for reoperation, while aging, locking plate usage, and higher body mass index (BMI) were protective factors (all P < 0.05). The locking plate featured a significantly decreased implant removal rate (7.7% vs. 60.9%, P < 0.05). Conclusions: Patients with risk factors for superficial wound infection or a prominent implant tended to require a secondary operation after surgery for midshaft clavicle fracture, while aging, pre-contoured locking plate usage, and higher BMI decreased the risk. Compared with DCP, patients with locking plates tended to have better prognosis and significantly lower implant removal rates. Level of evidence: Prognostic III.
