ICD-10: M21.2

The ICD-10 code M21.2 pertains to "Flexion deformity," which is classified under the broader category of acquired deformities of the limbs. This code is essential for healthcare providers when documenting and coding conditions related to joint deformities, particularly those that affect the range of motion and functionality of the limbs.

Clinical Description of Flexion Deformity

Definition

Flexion deformity refers to a condition where a joint is unable to fully extend, resulting in a permanent bent position. This can occur in various joints, including the shoulders, elbows, knees, and fingers. The deformity can be unilateral (affecting one side) or bilateral (affecting both sides), and it may vary in severity.

Causes

Flexion deformities can arise from several underlying conditions, including:
- Neuromuscular Disorders: Conditions such as cerebral palsy or muscular dystrophy can lead to muscle imbalances and joint deformities.
- Trauma: Injuries to the joint or surrounding tissues can result in scarring or contractures that limit movement.
- Arthritis: Chronic inflammatory conditions can lead to joint damage and subsequent deformities.
- Congenital Conditions: Some individuals may be born with structural abnormalities that predispose them to flexion deformities.

Symptoms

Patients with flexion deformities may experience:
- Limited range of motion in the affected joint.
- Pain or discomfort, particularly when attempting to extend the joint.
- Muscle weakness or atrophy around the affected area.
- Functional limitations in daily activities, depending on the severity and location of the deformity.
