Summary
This study details spinoglenoid ligament anatomy in cadavers, finding variations in its insertion points. No hypertrophic ligaments were observed that could compress the suprascapular nerve.
Area of Science:
- Orthopedic anatomy
- Human cadaveric studies
Background:
- The spinoglenoid ligament is a key structure in shoulder anatomy.
- Understanding its variations is crucial for diagnosing and treating shoulder pathologies.
Purpose of the Study:
- To describe the anatomical variations of the spinoglenoid ligament.
- To investigate potential associations between ligament morphology and suprascapular nerve compression.
Main Methods:
- Dissection of 27 shoulders from 15 human cadavers.
- Detailed examination and documentation of spinoglenoid ligament origin, insertion, and number.
Main Results:
- One or two distinct spinoglenoid ligaments were identified in all shoulders.
- Ligaments originated from the scapular spine base and inserted on the scapular neck or joint capsule.
- No instances of hypertrophic spinoglenoid ligaments potentially compressing the suprascapular nerve were found.
Conclusions:
- The spinoglenoid ligament exhibits anatomical variations in its insertion.
- The observed ligament morphology in this cohort did not suggest a risk for suprascapular nerve compression.
