Background: Ulnar collateral ligament (UCL) has the main function to be stress-resistant to elbow valgus overload. Multilayer tears require a reconstruction with a tendon graft. In this study, we report the clinical, radiographic, and ultrasound outcomes after tendon graft reconstruction for symptomatic UCL insufficiency. Materials and methods: Among twenty-six subjects underwent elbow UCL reconstruction from 2006 to 2012, fifteen were available to be evaluated at a mean follow-up of 36 months. Preoperative assessment included clinical examination and MRI. The outcome measures were the Mayo Elbow Performance Score (MEPS); the Oxford Elbow Score (OES); the Disabilities of the Arm, Shoulder, and Hand (DASH); and the Conway-Jobe Scale. Overall population was postoperatively investigated with X-ray and ultrasound (US). Reconstruction was performed with autograft (palmaris longus) in five cases and allograft (semitendinosus) in ten cases using the figure-of-eight configuration (five cases), the docking technique (eight cases), or a fixation with screws (two cases). Results: We found a significant improvement in postoperative MEPS, OES, and DASH scores (p < 0.01). One case was unsatisfied and required an additional procedure of ulnar nerve transposition 12 months after the reconstruction. X-ray showed calcifications along the graft in ten cases. At US examination, all the grafts assessed appeared anatomically intact without structural changes, and the dynamic examination showed a slight medial laxity with the valgus stress maneuver without pain or other sign of medial instability. Conclusions: This study confirms the efficacy of the graft reconstruction for chronic UCL insufficiency and introduces fresh insight on the role of musculoskeletal ultrasound to evaluate the reconstructed UCL. © 2014 Istituto Ortopedico Rizzoli.

Abstract

Background: Ulnar collateral ligament (UCL) has the main function to be stress-resistant to elbow valgus overload. Multilayer tears require a reconstruction with a tendon graft. In this study, we report the clinical, radiographic, and ultrasound outcomes after tendon graft reconstruction for symptomatic UCL insufficiency. Materials and methods: Among twenty-six subjects underwent elbow UCL reconstruction from 2006 to 2012, fifteen were available to be evaluated at a mean follow-up of 36 months. Preoperative assessment included clinical examination and MRI. The outcome measures were the Mayo Elbow Performance Score (MEPS); the Oxford Elbow Score (OES); the Disabilities of the Arm, Shoulder, and Hand (DASH); and the Conway-Jobe Scale. Overall population was postoperatively investigated with X-ray and ultrasound (US). Reconstruction was performed with autograft (palmaris longus) in five cases and allograft (semitendinosus) in ten cases using the figure-of-eight configuration (five cases), the docking technique (eight cases), or a fixation with screws (two cases). Results: We found a significant improvement in postoperative MEPS, OES, and DASH scores (p < 0.01). One case was unsatisfied and required an additional procedure of ulnar nerve transposition 12 months after the reconstruction. X-ray showed calcifications along the graft in ten cases. At US examination, all the grafts assessed appeared anatomically intact without structural changes, and the dynamic examination showed a slight medial laxity with the valgus stress maneuver without pain or other sign of medial instability. Conclusions: This study confirms the efficacy of the graft reconstruction for chronic UCL insufficiency and introduces fresh insight on the role of musculoskeletal ultrasound to evaluate the reconstructed UCL. © 2014 Istituto Ortopedico Rizzoli.
