Primary repair of severely retracted nonchronic distal biceps tendon rupture using 2-incision anterior-approach repair

Background Primary repair of a severely retracted distal biceps tendon can pose a technical challenge. We sought to describe the method and clinical outcomes of a surgical technique used as an adjunct to the conventional anterior single-incision repair for severely retracted biceps tendons. This technique involves a second anterior incision proximally to retrieve a severely retracted tendon followed by passing the tendon through a soft-tissue tunnel. Methods We identified 30 consecutive patients who had undergone a primary distal biceps tendon repair by an anterior-approach cortical-button technique. A phone survey was conducted for patient-reported outcomes. Patients returned for bilateral forearm supination strength testing in 2 positions (45o of pronation and 45o of supination). Outcomes were compared between patients who required a second incision and high elbow flexion (>60o) because of severe tendon retraction and those who did not require such interventions. Results No significant differences in elbow range of motion, supination strength, or patient-reported outcomes were found between the 2 groups of patients (P > .05). Regarding supination strength, the operated side was significantly weaker than the uninjured side in both pronated and supinated positions (P Conclusions Severely retracted distal biceps tendons can be successfully repaired using a second incision and high elbow flexion without negative effects on the outcomes. Supination strength was decreased following an anterior-approach cortical-button technique, but patient-reported outcomes were not affected negatively.
