Evaluation of unstable shoulders by computed tomography. A preliminary study
The American Journal of Sports Medicine
|May 1, 1982
Summary
Computed tomography (CT) effectively diagnoses Hill-Sachs lesions in patients with shoulder instability when routine radiography is inconclusive. This advanced imaging modality aids in identifying associated Bankart deformities for comprehensive evaluation.
Area of Science:
- Orthopedic Surgery
- Radiology
- Medical Imaging
Background:
- Glenohumeral joint instability presents diagnostic challenges.
- Hill-Sachs lesions are common in shoulder instability.
- Radiography may not always detect subtle bone abnormalities.
Observation:
- Three cases of glenohumeral joint instability were reviewed.
- Computed tomography (CT) was used as an adjunctive diagnostic tool.
- Routine radiography identified Hill-Sachs lesions in two patients, with equivocal findings in the third.
Findings:
- CT confirmed the presence of Hill-Sachs lesions in all three patients.
- A Bankart deformity was identified in one patient via CT.
- CT proved valuable in definitively diagnosing bone lesions associated with instability.
Implications:
- Computed tomography offers enhanced diagnostic accuracy for shoulder instability.
- CT can reveal associated pathologies like Bankart deformities.
- This modality improves the evaluation of complex shoulder instability cases.
