Summary
The Putti-Platt procedure enhances subscapularis tendon strength and shoulder stability for recurrent anterior dislocation. MRI shows increased tendon size and improved muscle fiber alignment post-surgery.
Area of Science:
- Orthopedic Surgery
- Radiology
- Sports Medicine
Background:
- Recurrent anterior shoulder dislocation poses a significant clinical challenge.
- The Putti-Platt procedure is a surgical intervention aimed at stabilizing the shoulder joint.
Observation:
- Magnetic resonance imaging (MRI) was utilized to assess changes in shoulder anatomy before and after the Putti-Platt procedure.
- Six patients with recurrent anterior shoulder dislocation underwent pre- and post-operative MRI evaluations.
Findings:
- Post-Putti-Platt procedure, MRI revealed subscapularis tendon thickening and increased T2-weighted signal intensity in four patients.
- Subscapularis tendon area increased up to 3.46-fold, with a 1.51-fold average volume increase.
- Subscapularis muscle fibers transitioned from a mild arc to a straighter course in five patients.
Implications:
- The Putti-Platt procedure appears to significantly enhance subscapularis tendon strength.
- The findings suggest improved laxity of the subscapularis muscle, contributing to glenohumeral joint stability.
- This surgical technique shows promise as an effective treatment for recurrent anterior shoulder dislocation.
