Purpose
Reconstruction of the ruptured distal biceps tendon is best done with a cortical button technique according to recent biomechanical studies. However, clinical outcome studies that evaluate the cortical button reconstruction technique are scarce. The purpose of this study was to evaluate the results of a cortical button reconstruction technique in patients with a traumatic distal biceps tendon rupture.
Methods
Twenty-two patients with 24 traumatic distal biceps tendon ruptures underwent surgical treatment. Reconstructions were done using the Endobutton or Toggle Loc. Postoperative evaluation consisted of ROM, strength, stability, neurological status and standard radiographs in AP view and lateral direction. The Mayo Elbow Performance Index (MEPI) and quick Disabilities of Arm, Shoulder and Hand (qDASH) questionnaires were also obtained.
Results
At a median follow-up of 22 months, the mean strength for flexion was 100 % (SD 21.3) and for supination 97 % (SD 7.8), compared to the contralateral side. There were complications in 8 patients (36 %), and heterotopic ossifications were seen on radiographs in 23 % of patients. Heterotopic ossifications were symptomatic in one patient.
Conclusions
The results after distal biceps tendon refixation with a cortical button were good according to ROM, MEPI and qDASH scores and strength. However, this procedure was accompanied with complications; in particular, the formation of heterotopic ossifications was frequently seen, though clinically relevant in only one patient.
Level of evidence
Case series, Level IV.
