| 520 | 3 | |a Purpose: The aim of this biomechanical in vitro study was to compare the novel technique of double intramedullary cortical button (DICB) fixation with the well-established method of suture anchor (SA) fixation for distal biceps tendon repair. Methods: A matched-pair analysis (24 human cadaveric radii) was performed with respect to cyclic loadings and failure strengths. Twelve specimens per group were cyclically loaded for 1,000 cycles at 1.5Hz from 5 to 50N and from 5 to 100N, respectively. The tendon-bone displacement was optically analysed using the Image J Software (National Institute of Health). Afterwards, all specimens were pulled to failure. Maximum load to failure and mode of failure were recorded. Results: All DICB constructs passed the cyclic loading test, whereas 4 of the 12 specimens within the SA group failed by anchor pull-out. Cyclic loading showed a mean tendon-bone displacement of 0.6±1.4mm for the DICB group and 1.4±1.4mm for the SA group (n.s.) after 1,000 cycles with 50N, and a mean displacement of 2.1±2.4mm for the DICB group and 3.5±3.7mm for the SA group (n.s.) after 1,000 cycles with 100N. Load to failure testing showed a mean failure load of 312±76N and a stiffness of 67.1±11.7N/mm for the DICB technique. The mean load to failure for the SA repair was 200±120N (n.s.) and the stiffness was 55.9±21.3N/mm (n.s.). Conclusions: The novel technique of DICB fixation showed small tendon-bone displacement during cyclic testing and reliable fixation strength to the bone in load to failure. Moreover, all DICB constructs passed cyclic loadings without failure. Based on the current findings, a more aggressive postoperative rehabilitation may be allowed for the DICB repair in clinical use. | |
