How is a Stener lesion diagnosed?
Injury to the ulnar collateral ligament (UCL) of the thumb requires imaging for diagnosis of surgically important entities such as the Stener lesion. Historically, routine radiography including stress views does not allow such diagnosis and is potentially detrimental to patient care.
What is a Stener lesion?
A Stener lesion occurs when the thumb is forcefully abducted and the distal attachment of the ulnar collateral ligament (UCL) at the metacarpophalangeal (MCP) joint is traumatically avulsed from its insertion into the base of the proximal phalanx of the thumb.
How do you check for a torn UCL in your thumb?
The torn ligament makes gripping and pinching painful, and joint instability can lead to arthritis over time….SIGNS AND SYMPTOMS
- Pain and tenderness over the joint at the base of the thumb.
- Thumb joint swelling / stiffness / bruising.
- Sensation of weakness or “giving way” of the thumb when pinching or gripping.
How do you tell if you have a torn ligament in thumb?
You may have bruising, tenderness, and swelling around the base of your thumb, near the palm. If the ulnar collateral ligament is completely torn, the end of the ruptured ligament may cause a lump or swelling on the inside of the thumb. Your thumb joint may also feel loose or unstable.
Can gamekeeper’s thumb be treated nonoperatively?
Nonoperative treatment can be considered for partial tears (grade I or grade II) of the UCL, which usually involve an isolated rupture of the proper collateral portion of the ligament. This may be treated with immobilization in a thumb spica-type cast for 4 weeks.
How long does it take to recover from a thumb ligament surgery?
Grip and hand strength may come back as early as 3 – 4 months after surgery, but it can take up to 6 – 12 months to fully recover and obtain maximum improvement. In most cases, you will be transitioned to a cast at your follow up appointment and then a removable brace at approximately 6 weeks post-surgery.
Does a torn thumb ligament require surgery?
The ligament is completely torn or is pulled off its attachment to the bone. These are significant injuries that require medical or surgical care. If the ligament tears away from the bone, it may take a small chip of the bone with it. This is called an avulsion fracture.
