Background: The aim of this study was to evaluate the clinical outcome and complication spectrum after delayed repair surgery of distal biceps tendon ruptures, postulating that satisfactory results are possible contrary to previous literature. Methods: Forty-three of 92 patients with a full workup (= OPT in) undergoing primary distal biceps tendon repair were included in this study. The mean age of participants was 49.5 years (range = 22-66 years). This cohort was divided into two groups: patients undergoing acute repair (21 days = SR group). Beside clinical evaluation, functional scores and detection of heterotopic ossification were documented. Strength of flexion and supination were measured using a BIODEX multipoint system. In addition, thirty-one patients were included only in the evaluation of complications in the absence of consent for clinical examination (= OPT out). Results: Concerning the OPT-in group, twenty-eight patients (ø age = 48.9 years; 22-63 years) received acute repair after an average of 9.2 ± 3.7 days. On the contrary, 15 patients (ø age = 50.5 years; 32-66 years) were treated with a delay after an average of 31.4 ± 10.4 days. Regarding patient-reported outcome measures, conflicting results emerge (AR/SR: Subjective Elbow Value = 87/80%, P > .05; Mayo score = 96/93 pts, P > .05; the Disabilities of the Arm, Shoulder and Hand score = 6/13 pts, P < .05; and Oxford Elbow Score = 44/39 pts, P < .05). The main complication is the paresthesia of the lateral antebrachial cutaneous nerve, which occurs more in the group of delayed repair (AR: 21.0%, SR 31.8%). Forty-one percentage of patients in the SR group described pain in the elbow with exertion in contrast to 17.3% in the AR group. In terms of elbow strength, no significant difference in the AR or SR group compared with the contralateral side could be observed. Conclusion: The data suggest that delayed repair of distal biceps ruptures beyond 3 weeks may result in satisfactory clinical outcomes. However, exertional pain and paresthesia of the lateral antebrachial cutaneous nerve may diminish results.
