Abstract
PURPOSE: The studies comparing the fixation methods being used for the ruptured distal biceps brachii tendon reinsertion show similar outcomes of cortical button and suture anchors usage, however, longer follow-up studies remain necessary. The goal of this study was to compare the clinical and functional three-year outcomes of the cortical button in contrast to the suture anchor fixation. METHODS: A retrospective cohort study comprised of 28 males on average 3 years after surgical reinsertion of the distal biceps brachii tendon with the use of a cortical button (Group I, n = 11) or a suture anchor (Group II, n = 17). The outcomes assessed were range of elbow joint and forearm motion (ROM), arm circumferences, visual analogue scale (VAS), Mayo Elbow Performance Index (MEPI), Quick Disability of the Arm, Shoulder, and Hand (Quick DASH) and forearm flexor and supinator muscle torques measured under isometric and isokinetic conditions. RESULTS: The comparison between the two studied groups revealed no statistically significant differences in ROM (p = 0.24-1.00), circumferences (p = 0.15-0.50), VAS (p = 0.71), MEPI (p = 0.23), Quick DASH (p = 0.61) or in the obtained muscle torque values (p = 0.07-1.00). However, differences in supination ROM between the surgical and non-surgical side were found in both groups (p = 0.01-0.02), and differences in pronation (p = 0.02) were found in Group II. The muscle torque values obtained in the surgical, dominant limb were lower than those in the nonsurgical, nondominant limb. CONCLUSION: The comprehensive comparison of three-year outcomes of cortical button versus suture anchor fixations did not favour one fixation method over the other, and the results justify the clinical usage of both methods.
