[Ligamental injuries of MCP joints (author's transl)]

Injuries of the ligaments and capsule of the MCP joints are frequently seen in the hand surgical service. A great part of these injuries are caused by trauma during competitive athletic games. Capsule and ligamental injuries of the 3rd and 4th digit can be treated conservatively by fixation to the next digits. Ruptures of the collateral ligaments of the 1st, 2nd and 5th digit as well as injuries with accompanying fracture or joint instability have to be surgically repaired. The different types of ligamental ruptures and their surgical treatment are discussed.
