Anatomic Medial Ulnar Collateral Ligament Reconstruction With Internal Brace Augmentation in Throwing Athletes

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanics

Background:

• Medial ulnar collateral ligament (MUCL) injuries are common in throwing athletes, often necessitating lengthy rehabilitation.
• Existing reconstructive methods may not fully restore MUCL anatomy.
• This study introduces an "anatomic technique" for MUCL reconstruction augmented with internal bracing.

Purpose of the Study:

• To present an "anatomic technique" for medial ulnar collateral ligament (MUCL) reconstruction.
• To evaluate the efficacy of internal brace augmentation in MUCL repair.
• To assess the return-to-play rates and timelines for athletes undergoing this procedure.

Main Methods:

• A detailed description of the "anatomic technique" for MUCL reconstruction is provided.
• The technique involves native ligament repair supplemented by graft augmentation and internal bracing.
• Sutures are passed through the torn ligament and secured via bone tunnels and suture anchors.

Main Results:

• Over 90% of the 26 professional and amateur throwers in the cohort returned to play at their previous level.
• The average return-to-play time was 9.9 months postoperatively.
• The "anatomic technique" with internal bracing demonstrated high success rates.

Conclusions:

• Anatomic reconstruction of the MUCL using internal bracing is a feasible and effective treatment option.
• This approach can potentially expedite the return to sport for athletes with MUCL injuries.
• The described technique aims to improve outcomes and reduce recovery time for throwing athletes.
