Ulnar Collateral Ligament Repair With Suture Bridge Augmentation.

ABSTRACT: The gold standard for management of elbow ulnar collateral ligament (UCL) injuries in elite athletes is reconstruction of the UCL with a tendon graft. Over the past several years, UCL repair for acute tears, as well as partial tears, in young athletes has gained increasing popularity, with studies reporting good outcomes and high rates of return to sports. Additionally, there is increased interest in ligament augmentation using the InternalBrace concept. A recent technique paper describes a direct repair of the UCL augmented with a spanning suture bridge. Although clinical outcomes for this method are promising, one possible concern when using this technique is bone loss at the ulnar origin of the UCL should revision reconstruction be required. We propose an alternative augmentation method that allows for stress shielding of the healing native ligament while minimizing bone compromise in the face of UCL reconstruction at a later time point.

Project description:BackgroundReconstruction is the gold standard treatment for medial ulnar collateral ligament (MUCL) injuries. However, recent studies show a successful and renewed interest in direct suture repair, particularly in young athletes. Repair augmentation with a suture tape may provide greater stability, enabling healing of the MUCL while protecting the repair at higher valgus loads.PurposeTo perform a systematic review and meta-analysis on whether MUCL repair with augmentation provides a similar biomechanical profile to the traditional MUCL reconstruction.Study designSystematic review.MethodsThe Cochrane Controlled Register of Trials, PubMed, Medline, and Embase were used to perform a systematic review and meta-analysis using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria with the following search terms: ("ulnar collateral ligament" OR "medial ulnar collateral ligament") AND ("internal brace" OR "augmentation" OR "suture tape"). Data pertaining to certain biomechanical properties (gap formation, failure to torque [ultimate load to failure], stiffness, degree of valgus opening, and modes of failure) were extracted. The pooled outcome data were analyzed by random- and fixed-effects models. A total of 203 abstracts were identified through the aforementioned databases.ResultsAfter abstract and full-text screening, 6 biomechanical studies were included. All were on cadaveric elbows, with 53 repairs with augmentation and 53 reconstructions compared. There were no differences between the 2 in regard to ultimate load to failure (standard mean difference [SMD], -0.34 N·m; 95% CI, -1.36 to 0.68; P = .51) and rotational stiffness (SMD, 0.26; 95% CI, -1.14 to 1.66; P = .72). Despite a trend in resistance to gapping with augmented repair, this was not significant (SMD, -0.53; 95% CI, -1.08 to 0.01; P = .06). Augmented repairs were more likely to fail by pullout or at the suture-tendon/anchor-suture interface (odds ratio [OR], 12.19; 95% CI, 4.17 to 35.62; P < .00001), while failure by fracture was more common with reconstruction (OR, 5.75; 95% CI, 2.07 to 15.99; P = .0008).ConclusionMUCL augmented repair establishes the required time-zero structural properties without the need for a tendon graft. However, future clinical studies are necessary to determine its true effectiveness as well as its success at higher levels of professional sport.
