Stener-like lesions due to radial collateral ligament rupture in the metacarpophalangeal joints of two adjacent fingers: A case report and review of literature.

Rupture of the collateral ligaments in the metacarpophalangeal (MCP) joint of a finger is less common than in the thumb. Literature about these lesions is sparse but the number of chronic injuries reported underlies the number of cases overlooked by physicians at the first visit. A Stener-like lesion is characterized by interposition of the extensor hood or the sagittal band between the torn collateral ligament of the MCP joint of a finger and its insertion. It was originally described as interposition of the adductor aponeurosis of the thumb. We present the first case of a Stener-like lesion in ruptured radial collateral ligaments of the MCP joint of two adjacent fingers.
