ICD-10: S56.51

The ICD-10 code S56.51 refers to a strain of other extensor muscle, fascia, and tendon at the forearm level. This classification is part of the broader category of injuries affecting muscles, fascia, and tendons, specifically focusing on the extensor muscles located in the forearm region.

Clinical Description

Definition

A strain is defined as an injury to a muscle or tendon that occurs when the muscle fibers are overstretched or torn. In the case of S56.51, the injury specifically involves the extensor muscles, which are responsible for extending the wrist and fingers. These muscles play a crucial role in various activities, including gripping, lifting, and performing fine motor tasks.

Anatomy Involved

The extensor muscles of the forearm include several key muscles, such as:
- Extensor carpi radialis longus
- Extensor carpi radialis brevis
- Extensor carpi ulnaris
- Extensor digitorum
- Extensor indicis
- Extensor pollicis longus and brevis

These muscles originate from the lateral epicondyle of the humerus and extend down the forearm to insert on the bones of the wrist and fingers. The fascia and tendons associated with these muscles are also involved in the strain.
