Objectives/Interrogation: The aim of this work is to compare the results achieved with two different techniques on the primary repair of Stener lesion.
Methods: The patients (N = 16) with stener lesion were divided in two groups according to the surgical procedure: Group 1 (n = 7) - reattach with miniature intra-osseus suture anchor and Group 2 (n = 9) reattach with pre-fashioned steel wire, the Barb-wire of Jennings (Tendofil®). The clinical assessment included a physical examination and functional testing (QuickDash score, range of motion, grip strength, pinch strength, instability and pain).
Results and Conclusions: The sample average age was 47.8 years (25 to 69 years) with an average follow-up of 57 months (24 to 101 months). The QuickDash score on group 1 was on average 16,5 and on group 2 18,6. The reduction of the grip and pinch strength on both groups was less than 10%. The loss of metacarpo-phalangeal (MP) joint motion was on average 5 degrees. There were no nerve injuries, infections, device failures or reoperations recorded. Persistent instability was not observed in any of the patients. Controlled active range of motion exercises started 3 to 4 weeks after open surgical repair. Protective splinting was continued until the sixth week and unrestricted use allowed at 12 weeks after injury.
The authors concluded that these two methods are safe and effective for repair of complete tears of the ulnar collateral ligament of the first MP joint, verifying a slightly better DASH score with the reattach using miniature intra-osseus suture anchor. There were no significant statistical differences in the grip and pinch strength. In general both have yielded good joint stability and a near-full recover of range of motion, showing a good to excellent functional outcome.
