Abstract
Background:Several techniques of surgical repair of biceps tendon ruptures are described in literature. Cortical button repair have shown minimal loss of elbow flexion, supination and strength. In this retrospective study we report the outcomes in terms of elbow function and complications of tension-slide technique and interference screw.Matherials and methods:14 patients with complete distal biceps tendon rupture were included in the retrospective study and treated with the same tension-slide technique (BicepsButton® - Arthrex, Inc, Naples, Florida) evaluating the clinical and functional outcomes and the complication rate with a follow-up average of 18 months.Results:The flexion recovered compare to the healthy contralateral was 96% (min 115° - max 135°; average 128°), the extension was 97% (min: -2° - max 15°; average 4°), the supination was 90% (min 20° - max 90°; average 75°), the pronation was 95% (min 15° - max 90°; average 76°). The mean Disabilities of Arm, Shoulder and Hand (DASH) score was 8.1 ± 10.5 and Mayo Elbow Performance Score overall (MEPS) score was 97.6 ± 8.2. Two patients had LABCN paresthesia, one case, treated 2 months after injury, had posterior interosseus nerve palsy. One patient had heterotopic ossification at the radiological examination without consequences for the clinical performances. No case of non-traumatic tendon re-rupture and no case of ROM deficiency > 20%. In all case the cortical button remains well positioned and no case of osteolysis were reported.Conclusions:Distal biceps tendon repair with BicepsButton® system seems to be a safe, relyable and reproducible technique providing excellent clinical, functional and radiological outcomes. Comparing with other techniques the BicepsButton® system has the advantages of the single approach procedures, the reduction of surgical time and risk of heterotopic ossifications.
