ICD-10: M21.172

The ICD-10 code M21.172 refers specifically to a varus deformity of the left ankle that is not classified elsewhere. Understanding this condition requires a closer look at its clinical description, implications, and relevant details.

Clinical Description of Varus Deformity

Definition

A varus deformity is characterized by an inward angulation of the distal segment of a bone or joint. In the context of the ankle, this means that the foot tilts inward relative to the leg, which can lead to an abnormal gait and various complications if left untreated. This condition can affect the alignment of the lower extremities and may result in pain, instability, and increased risk of injury.

Etiology

Varus deformities can arise from various causes, including:
- Congenital factors: Some individuals may be born with structural abnormalities that predispose them to varus deformities.
- Acquired conditions: These may include trauma, arthritis, or neurological disorders that affect muscle tone and joint stability.
- Post-surgical changes: Previous surgeries on the ankle or foot can lead to misalignment and subsequent varus deformity.

Symptoms

Patients with a varus deformity of the left ankle may experience:
- Pain or discomfort in the ankle or foot, particularly during weight-bearing activities.
- Difficulty walking or running due to altered biomechanics.
- Swelling or inflammation around the ankle joint.
- Increased wear on shoes, particularly on the inner side.

Diagnosis

The diagnosis of a varus deformity typically involves:
- Clinical examination: A healthcare provider will assess the alignment of the ankle and foot, looking for signs of deformity and evaluating the range of motion.
- Imaging studies: X-rays or MRI may be utilized to visualize the bone structure and assess the degree of deformity, as well as to rule out other underlying conditions.

Treatment Options

Management of a varus deformity may include:
- Conservative measures: Physical therapy, orthotic devices (such as ankle-foot orthoses), and pain management strategies can help alleviate symptoms and improve function.
- Surgical intervention: In cases where conservative treatment is ineffective, surgical options may be considered to realign the bones and restore normal function.
