Imaging studies, such as X-rays or Magnetic Resonance Imaging (MRI), are often utilized to confirm the diagnosis and rule out associated fractures or other soft tissue damage. These ligaments function on the sides of each joint, preventing excessive side-to-side movement and ensuring that the fingers operate smoothly within their intended range of motion.
Fall On Outstretched Hand Damage and Collateral Ligament Injuries
Common Injuries and Mechanisms Injuries to the collateral ligaments typically occur due to forced trauma that pushes the joint beyond its normal range of motion. Each finger joint features two distinct collateral ligaments: one on the ulnar side (medial) and one on the radial side (lateral).
A classic mechanism is a fall onto an outstretched hand with the fingers extended, or a direct blow to the side of the finger. The collateral ligaments of the hand are robust bands of fibrous tissue that provide essential stability to the metacarpophalangeal (MCP) and interphalangeal (PIP and DIP) joints.
