Does Stener lesion require surgery?
However, presence of a Stener lesion is a distinct, anatomic lesion that requires surgical correction. In cases of a complete, distal, thumb UCL tear, the aponeurosis of the adductor pollicis muscle can be interposed between the MCP of the joint and torn ligament.
What percentage of patients with a complete rupture are found to have a Stener lesion?
Stener lesions occur in 64% to 87% of all complete ruptures [6,7] and are usually treated by surgical repair. A Stener lesion.
How do you test for skiers thumb?
To perform a stress test, hold the MCP flexed to about 30°. Stabilise the metacarpal with one hand while using the other hand to push the MCP joint into radial deviation. A complete UCL tear will normally allow at least 15° greater radial deviation compared to the other thumb.

No surgical follow up is available.
What does a Stener lesion look like?
Radiographic features. a Stener lesion is proximal retraction of the ligament fibers which looks like a small mass displaced superficial to the adductor aponeurosis; this gives the yo-yo on a string appearance both on ultrasound and MRI images 5 passive flexion of the interphalangeal joint of the thumb during dynamic ultrasound imaging…
What is a Stener lesion on the MCP?
A Stener lesion is characterized by slippage of the torn end of the ulnar collateral ligament superficial to the adductor aponeurosis/ adductor pollicis muscle such that now there is interposition of the adductor pollicis muscle between the ulnar collateral ligament and the MCP joint. This prevents healing and is an indication for surgical repair.
