Abstract:
The pectoralis minor (PM) originates at the ribs medially and inserts at the medial border of the coracoid process. Pathologic shortening of the PM can be found in overhead athletes. A shortened PM is associated with anterior and internal rotation of the scapula, leading to scapular dyskinesis and anterior shoulder pain. Cases refractory to physical therapy and self-stretching exercises can be treated with isolated PM release. This procedure has been shown to be a safe and effective means of decreasing self-reported pain and activity limitations in patients with no other shoulder pathologies. We describe arthroscopic PM release in the beach-chair position in an athlete with recalcitrant shoulder pain and scapular dyskinesia.
Insights
Pathologic shortening of the pectoralis minor (PM) muscle can cause shoulder pain and scapular dyskinesis in athletes. Isolated PM release surgery effectively reduces pain and improves function in cases unresponsive to conservative treatment.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Anatomy
Background:
- Pathologic shortening of the pectoralis minor (PM) muscle is common in overhead athletes.
- Shortened PM can lead to scapular dyskinesis, internal rotation of the scapula, and anterior shoulder pain.
- Conservative treatments like physical therapy may not resolve symptoms in all cases.
Purpose of the Study:
- To describe the arthroscopic pectoralis minor release procedure.
- To evaluate the efficacy of isolated PM release in athletes with recalcitrant shoulder pain and scapular dyskinesia.
Main Methods:
- Arthroscopic pectoralis minor release performed in the beach-chair position.
- Focus on athletes with persistent shoulder pain and scapular dyskinesia unresponsive to conservative management.
Main Results:
- The procedure is safe and effective for reducing self-reported pain.
- Significant decrease in activity limitations was observed post-procedure.
- Successful management of recalcitrant shoulder pain and scapular dyskinesia.
Conclusions:
- Isolated arthroscopic pectoralis minor release is a viable treatment option.
- The procedure effectively addresses pain and functional deficits associated with PM shortening.
- This technique offers a solution for athletes with refractory shoulder pathologies.
