Clinical Description

Definition

A laceration is defined as a tear or a cut in the skin or underlying tissues, which can vary in depth and severity. In the context of S66.529, the laceration specifically involves the intrinsic muscles, fascia, and tendons of the fingers, which are crucial for fine motor skills and grip strength.

Intrinsic Muscles

The intrinsic muscles of the hand are those that originate and insert within the hand itself, as opposed to extrinsic muscles that originate in the forearm. These muscles are essential for the intricate movements of the fingers, including flexion, extension, abduction, and adduction. The intrinsic muscles include:

• Lumbricals: These muscles flex the metacarpophalangeal joints while extending the interphalangeal joints.
• Interossei: These muscles are responsible for the abduction and adduction of the fingers.
• Thenar and Hypothenar muscles: These groups control the movements of the thumb and little finger, respectively.

Fascia and Tendons

Fascia is a connective tissue that surrounds muscles, blood vessels, and nerves, providing support and structure. Tendons connect muscles to bones, allowing for movement. A laceration in this area can lead to significant functional impairment, depending on the severity and extent of the injury.

Clinical Implications
