Clinically Relevant Anatomy[edit | edit source]
Injury to the ulnar collateral ligament (UCL) at the metacarpophalangeal joint (MCPJ) of the thumb, also known as "skier's thumb," can involve other structures such as the adductor aponeurosis, the accessory collateral ligament, bony structures, tendons, and neurological tissues.[1]
There are two main supporting ligaments traversing the MCPJ of the thumb: the UCL and the radial collateral ligament (RCL). In general, UCL injuries account for 60-90% of ligamentous collateral injuries.[2] The UCL and RCL arise from the medial and lateral tubercles of the metacarpal condyles, respectfully, and insert into the base of the proximal phalanx on their respective sides (Figure 1).[2][3]
