Summary

The comparison of the clinical and functional outcome of cortical button versus suture anchor repair of distal biceps tendon injuries generally showed no differences between the studied fixation methods.

Abstract

Anatomic reinsertion of the distal biceps brachii tendon is the most commonly recommended primary treatment option for distal biceps injuries in appropriately indicated patients. In aim to improve fixation strength, to limit postsurgical complications and to allow early functional recovery, various surgical techniques of the tendon reinsertion have been described, mostly with comparable results in clinical outcomes and biomechanics.
The goal of the study was to compare the clinical and functional outcome of cortical button to titanium anchor repair of distal biceps tendon injuries.
The studied material consist of 25 males averagely 3 years after single-incision surgical reinsertion of the distal biceps brachii tendon with the use of cortical button (Group I, n=11) and suture anchor (Group II, n=14). There were found no statistically significant differences between the two studied groups in age, body height, body mass, the time between injury and surgery and in the time of postoperative physiotherapeutic procedure duration. The outcome was assessed with the use of range of forearm motion (ROM) and circumferences of elbow joint and arm measurements. All patients were scored with the visual analogue scale (VAS), Mayo Elbow Performance Index (MEPI) and Quick Disability of the Arm, Shoulder, and Hand (Quick DASH). The measurements of the forearm flexors and supinators muscles torques under isometric and isokinetic conditions with the two different angular velocities (60°/s and 180°/s) using Biodex 3 System were carried out. The obtained torques were normalized to body mass.
The inter-group statistical analysis revealed no statistically significant differences in forearm ROM and circumferences of involved limbs. No statistically significant differences between the studied groups were noted in VAS, MEPI and Quick DASH. The results of measured muscles torques under isometric and isokinetic conditions didn’t reveal any significant differences between the studied groups.
The comparison of the clinical and functional outcome of cortical button versus suture anchor repair of distal biceps tendon injuries generally showed no differences between the studied fixation methods. Because of the fact, that the patient-reported measures weren’t in line with objectively measured features, a patient assessment after repair of distal biceps brachii tendon injury should report both subjective and objective methods of evaluation.
