Techniques and Fixation of Olecranon Osteotomy: A Systematic Review.

We aimed to characterize the incidence of complications regarding olecranon osteotomy, looking more specifically at the type of osteotomy and the fixation construct used to repair the osteotomy. In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a comprehensive search was performed. A study was included if it was an adult clinical study, a transverse or chevron olecranon osteotomy was performed, and the study explicitly states the fixation construct used to repair the osteotomy. A quality assessment was performed in each study prior to data extraction. We included 39 studies with a total of 1,445 patients. Most studies included patients who were being treated primarily for a distal humerus fracture. The overall incidence of delayed union was 27/643 (4.2%), with a higher rate in transverse osteotomy than in chevron osteotomy (5/49 (10.2%) vs 22/595 (3.7%)). Nonunion occurred in 43/811 (5.4%) of patients, with a higher rate in transverse osteotomy (6/73 (8.2%) vs. 37/712 (5.2%)). Implant failure or loss of reduction occurred in 44/746 (5.9%) of patients, with a higher rate in transverse osteotomy (11/49 (22.4%) vs 33/688 (4.8%)). The removal of implants occurred in 236/1078 (21.9%) of all patients, with the highest rate in those studies that used plate fixation 44/99 (44.4%). Compared with chevron osteotomy, patients who underwent transverse osteotomy had a higher incidence of delayed union, nonunion, and implant failure or loss of reduction requiring revision surgery. The incidence of implant removal indicates that patients should be informed that nearly half of the osteotomy fixed with a plate was removed after implantation. Therapeutic III.
