Overview
Stress radiographs apply controlled force to evaluate ligamentous integrity and joint stability in the wrist and hand. They are performed under fluoroscopic guidance or with manual stress during radiography. Stress views help determine need for surgical stabilization.
Technique
Apply varus valgus or axial stress while obtaining targeted projections of the wrist or hand. Use protective measures and informed consent due to discomfort risk. Document the applied stress and technique used for reproducibility.
Clinical Indications
Stress views are indicated for suspected scapholunate instability ulnar collateral ligament injury and carpal instability. They assess dynamic widening or subluxation not evident on static views. MRI may be used to directly visualize ligament tears when needed.
Image Assessment
Measure joint space widening and compare with the contralateral side. Evaluate for dynamic subluxation and associated fractures. Report findings to guide orthopedic decision making and potential surgical repair.
