Arthroscopic tenoplasty in congenital split biceps long head

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Anatomy

Background:

• The long head of the biceps brachii tendon typically originates from the superior glenoid labrum and supraglenoid tubercle.
• Anatomic variations of the biceps brachii are uncommon.
• Congenital split biceps tendon is a rare anomaly.

Purpose of the Study:

• To describe a novel surgical technique, arthroscopic intra-articular biceps tenoplasty, for managing a congenital split biceps tendon.
• To report the first instance of this technique for restoring the long head of the biceps tendon using the superior capsule.
• To highlight the incidental finding of this anomaly during arthroscopic evaluation for shoulder instability and SLAP tear.

Main Methods:

• Arthroscopic intra-articular biceps tenoplasty was performed.
• The technique involved utilizing the superior capsule for tendon restoration.
• The procedure was conducted during diagnostic glenohumeral arthroscopy.

Main Results:

• Successful restoration of the long head of the biceps tendon was achieved using the described technique.
• The anomalous congenital split biceps tendon was incidentally identified.
• The patient was undergoing treatment for shoulder instability and a SLAP tear.

Conclusions:

• Arthroscopic intra-articular biceps tenoplasty is a viable technique for managing congenital split biceps tendon anomalies.
• This technique offers a method for restoring tendon integrity in rare anatomical variations.
• Prompt identification and management of such anomalies during shoulder arthroscopy are important.
