Summary
Sprengel deformity involves scapular dysplasia and malposition. Three-dimensional CT (3D-CT) revealed characteristic scapular shapes and inverse relationships between rotation and displacement, aiding surgical planning.
Area of Science:
- Orthopedics
- Radiology
- Pediatric Surgery
Background:
- Sprengel deformity is a congenital condition characterized by abnormal scapular position and shape.
- Understanding the specific morphological changes is crucial for effective surgical correction.
Purpose of the Study:
- To evaluate scapular dysplasia and malposition in Sprengel deformity using 3D-CT.
- To correlate imaging findings with the omovertebral connection and operative results.
Main Methods:
- Three-dimensional computed tomography (3D-CT) was used to assess 15 patients with Sprengel deformity.
- Detailed measurements of scapular shape, size, curvature, and glenoid version were performed.
- The degree of scapular rotation, superior displacement, and presence of omovertebral connections were evaluated.
Main Results:
- Affected scapulae typically exhibited a characteristic shape, decreased height-to-width ratio, and were larger than contralateral scapulae.
- An inverse relationship was observed between scapular rotation and superior displacement.
- The omovertebral connection's tethering point appeared to influence scapular morphology and position.
Conclusions:
- 3D-CT provides detailed delineation of scapular deformities in Sprengel syndrome.
- Imaging findings correlate with the omovertebral connection, offering insights into deformity genesis.
- This detailed assessment aids in planning effective scapuloplasty procedures.
