RCT on Nonoperative Versus Operative Treatment for Acute Complete tearS of the Ulnar Collateral ligAment of the Thumb

A cast to immobilize the MCP, in 10-30 degrees (slight) flexion (neutral position), and the CMC joint, in 30-40 degrees palmar abduction, is applied (IP joint is free).

"In general, two surgical techniques are described in literature and used in daily clinical practice:~* If the UCL is ruptured in the middle of the ligament, sutures are used to reattach the ligament remnants together.~* When no viable UCL ligaments are present, the UCL is reattached directly to the bone using suture anchors."
