Torn ulnar collateral

Two wks ago I had an accident at wk (dog grooming), my thumb was bent back. The er doc said there was a hairline fracture to follow up w/an orthopedic. They splinted it. Ten days later, at the orthopedic, he says the ligament is torn (ulnar collateral ligament). The thumb has no stability. He told me it needed either surgery or we put a cast on for 6 wks. He said that if it doesn't heal it may need surgery. How will we know? Will it still hurt? If it is still unstable does that mean surgery? I am just scared that this is going to cost me my career. I need my hands.How long will this put me out of wk?

Hi,
      How are you? Injury to the ulnar collateral ligament of the thumb is fairly common. This strong band of tissue is attached to the middle joint of the thumb, the joint next to the web space of the thumb. If there is a associated bone fracture then x-rays can help in making diagnosis. In isolated ligament injuries, valgus stress test with x-rays help in making diagnosis.

The goal of treatment is to help the ligaments heal so that the thumb can be restored to full function. In non-surgical treatment, your thumb will be immobilized for four to six weeks in a special cast, called a thumb spica cast. After that, you will begin to do exercises to regain your range of motion and to strengthen your grip.

If, this fails, then surgical management with fusion surgery or suture repair can be considered depending upon the requirement. Most patients are able to return to normal activity three months after their surgery.
Best.
