Bankart augmentation for capsulolabral deficiency using a split subscapularis tendon flap.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Arthroscopy

Background:

• Traumatic anterior shoulder instability is common and often necessitates surgical intervention.
• Arthroscopic capsulolabral repair is effective for instability without bone loss, but capsulolabral deficiency poses challenges.
• Previous treatments for severe deficiency include grafts or coracoid transfer.

Purpose of the Study:

• To describe a novel arthroscopic technique for Bankart augmentation in cases of capsulolabral deficiency.
• To present a method using a split subscapularis tendon flap to reinforce the damaged capsule.
• To evaluate this technique's potential in restoring anterior shoulder stability.

Main Methods:

• Description of a novel arthroscopic Bankart augmentation procedure.
• Utilizing a split subscapularis tendon flap to reinforce the deficient capsulolabral complex.
• Application in patients with traumatic anterior shoulder instability and capsulolabral deficiency, excluding significant bone loss.

Main Results:

• The technique aims to restore anterior shoulder restraint effectively.
• It is designed to avoid excessive constraint of the glenohumeral joint.
• Successful reinforcement of the damaged capsule is the primary outcome.

Conclusions:

• This novel arthroscopic Bankart augmentation using a subscapularis tendon flap offers a potential solution for capsulolabral deficiency.
• The technique can restore anterior shoulder stability in the absence of significant bone loss.
• It provides an alternative to grafts or coracoid transfer for complex shoulder instability.
