Both of these surgeries are performed in cases of anterior shoulder instability. The key differences between these two surgeries are given in the table below:
| Surgical Step | Latarjet | Bristow |
|---|---|---|
| Osteotomy site | Between coracobrachialis and pectoralis minor (~2 cm coracoid) | Immediately distal to pectoralis minor (~1 cm coracoid) |
| Method of osteotomy | Chisel | Bone cutters |
| Subscapularis approach | Vertical tenotomy | Horizontal split |
| Position of bone block | Inferior surface in contact with glenoid vault - ‘Lying down’ | Resected surface in contact with vault - ‘Standing up’ |
| Graft fixation | 2 screws | 1 screw |
| Coracoacromial ligament | Sutured to capsule | Preserved |
Hybrid bristow-latarjet coracoid transfer involves transfer of 2 cm coracoid to glenoid neck but the coraco-acromial ligament is preserved.
