Introduction:
Though long-term functional outcomes of olecranon fracture plate fixation are favorable, postoperative implant irritation commonly leads to elective removal. We hypothesized that mini-fragment plates will decrease implant removal compared to precontoured plates.
Methods:
Patients with isolated olecranon fracture (AO/OTA 2U1-B1) treated with plate fixation were retrospectively reviewed. Patients were stratified into groups based on whether they underwent open reduction and internal fixation with a (1) surgeon contoured mini-fragment or (2) precontoured olecranon-specific plate. Rates of symptomatic implants and implant removal were compared.
Results:
98 and 32 patients were treated with precontoured and mini-fragment plates, respectively. Baseline demographics and comorbidities were similar. Mean follow-up was 20.6 months. There were no differences in rates of postoperative complication (22/98, 22.4% vs. 5/32, 15.6%; p = 0.41) or reoperation (37/98, 37.8% vs. 8/32, 25%; p = 0.19). Symptomatic implants were common in the precontoured cohort (44/98, 44.9% vs. 7/32, 21.9%; p < 0.05). Implant removal rates were 36.7% and 18.8%, respectively (p = 0.06).
Discussion/Conclusion:
Olecranon fracture stabilization with mini-fragment plate is associated with lower rates of symptomatic implants, with no difference in postoperative complications or reoperations. Mini-fragment plating is a safe and promising alternative to precontoured plating.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
