Objective:
One-stage procedure for gaining adequate bone stock and rotator cuff repair.
Indications:
Tears of the rotator cuff in combination with bony cysts or reduced bone quality at the footprint.
Contraindications:
Allergies to contents of the bone void filler, fatty infiltration of infraspinatus and subscapularis of stage 3 and 4, narrowing of the subacromial space (< 7 mm).
Surgical Technique:
We report a one-stage technique for footprint reconstruction in a rotator cuff tear-associated greater tuberosity cyst by augmenting the cystic lesion with an injectable, absorbable, biocompatible, fiber reinforced bone void filler in combination with a double row rotator cuff reconstruction technique.
Postoperative Management:
The arm is placed in a shoulder-immobilizing abduction pillow to achieve 30° abduction for a period of 4-6 weeks. The physical therapy program includes passive mobilization of the affected shoulder to 60-90° flexion/abduction within the first 3 weeks. During the next 3 weeks, the passive mobilization is changed to active mobilization, starting with assisted exercises. Active exercises without limitation in range of motion are not allowed until the 7th week after surgery and moderate sports not until the third month post-surgery.
Results:
Six patients have been treated using the presented technique. However, long term results are still missing.
