Tension band wiring versus locking plate fixation for simple, two-part Mayo 2A olecranon fractures: a comparison of post-operative outcomes, complications, reoperations and economics

Simple displaced transverse olecranon fractures are traditionally managed operatively with a tension band wire device (TBW). We compared clinical outcomes, morbidity and the cost of treatment of TBW versus pre-countered low-profile locking plates for the treatment of Mayo 2A fractures.
Patient and methods
All olecranon fractures admitted to our unit between 2008 and 2014 were identified (n = 129). Patient notes and radiographs were studied from presentation to final follow-up. Patient outcomes were recorded using the QuickDASH (Disabilities of Arm, Shoulder and Hand) score. Patient demographics and nature of complications were recorded as were the rate and nature of any repeat operation.
Eighty-nine patients had Mayo 2A fractures (69%). Sixty-four underwent TBW (n = 48) or locking plate fixation (n = 16). The mean ages of both groups were similar at 57 (15–93) and 60 (22–80), respectively. In the TBW group, the mean post-injury QuickDASH was 12.9, compared with 15.0 for the locking plate group. There was no statistically significant difference between the outcomes for either group. Nineteen of the 48 TBW patients had complications (39.6%). Sixteen of the 48 TBW patients had reoperations (33.3%). In particular, we would highlight that 13 (27.1%) of patients treated with TBW underwent subsequent removal of metalwork for hardware irritation. There were no complications and or reoperations in the 16 patients who received locking plate fixation. Both complication and reoperation rates were statistically significantly different. Despite being initially more expensive, when the cost of reoperation for TBW group was included, locking plates were found to be on average £236.33 less per patient than for TBW.
We suggest that locking plates are superior to TBW concerning post-operative morbidity, reoperation rate and cost for Mayo 2A fractures in contrast to previous articles.
