title: Comparison of Outcomes and Costs of Tension-Band and Locking-Plate Osteosynthesis in Transverse Olecranon Fractures: A Matched-Cohort Study.
abstract: To determine if there are significant differences in outcomes and costs between tension-band and locking-plate fixation of transverse olecranon fractures in adults, we retrospectively compared functional outcomes, complications, and costs in 2 cohorts of displaced transverse olecranon fractures. These cohorts (10 patients each) were matched on age and length of follow-up. There were no significant differences between the groups in range of motion, functional scores, or arthrosis. There were no infections or nonunions in either group. There was no significant difference in rate of implant removal or symptomatic implants, though a trend was found toward a higher rate of both with tension bands. Operative time was significantly (P = .025) less for tension-band than locking-plate fixation (55 vs 85 minutes). In the tension-band group, charges were significantly less for implant, index procedure, and overall operative charges including reoperations ($6598.36 vs $14,333.46; P = .001). If all tension bands and no locking plates had been removed, tension-band fixation still would have cost significantly less ($7307.31 vs $14,160.26; P = .0005).
