Summary
Detailed bony dimensions of adult scapulae were measured. The glenoid process showed the thickest bone, while the scapular spine varied in thickness, offering insights for treating scapular fractures.
Area of Science:
- Orthopedic surgery
- Anatomy
Background:
- Scapular fractures are complex injuries.
- Accurate bony dimensions are crucial for surgical repair.
Purpose of the Study:
- To provide detailed bony measurements of the adult scapula.
- To aid in the surgical management of scapular fractures.
Main Methods:
- Thirty adult bony scapulae were analyzed.
- Measurements included glenoid, coracoid, spine, and body dimensions.
- Specific diameters (posteroanterior, superoinferior) were recorded.
Main Results:
- The glenoid process had the thickest bone (13-23 mm posteroanterior diameter).
- Scapular spine thickness varied, with the smallest diameter (2-7 mm superoinferior) in the middle section.
- Lateral border bone thickness was greater superiorly (8 mm) than inferiorly (6 mm).
Conclusions:
- These detailed scapular bone measurements offer valuable data.
- The findings can assist in open reduction and internal fixation of scapular fractures.
