Outcomes of distal biceps tendon repair using a dual incision, cortical button technique: a single surgeon study
Abstract
Background: The purpose of this study was to evaluate patient-reported outcomes, function, complication rates, and radiographs in a series of patients with distal biceps tendon repair using the dual incision cortical button technique by a single surgeon. By having a single surgeon perform the surgery, the technique is standardized to all patients. Twenty-two patients consented to participate in the study. The average time from surgery to review was 2.2 years. Patient satisfaction was assessed using the DASH, Oxford, and Mayo Elbow Performance Scores. Methods: Range of movement was assessed and compared to the unaffected limb using a goniometer. Isometric flexion and supination strength was tested using a standardized dynamometer—both measurements taken by a single physiotherapist. Radiographs were discussed at the time of the review by 2 orthopedic surgeons to check for heterotopic ossification. Results: The mean DASH score was 6.3 postsurgery at the time of follow-up. There was no significant difference in active range of movement between the repaired and nonrepaired arm in flexion, extension, supination, or pronation. Four radiographs showed evidence of heterotopic ossification (HTO)—none showed synostosis. For patients with HTO, there was evidence that supination was inhibited compared to those patients who did not have HTO. Conclusion: Our study found that at an average of 2 years of follow-up these patients had good outcomes clinically with no major complications. HTO was present in only 4 patients, and there was a significant difference in supination compared to those who did not have HTO. These patients had an average DASH of 14 compared to a score of 4.5 in those who did not have an HTO. The study showed that the dual incision cortical button repair remains a procedure with excellent patient outcomes at the risk of HTO.
