Varus deformity, classified under ICD-10 code M21.17, refers to a specific type of limb deformity characterized by an inward angulation of the distal segment of a bone or joint. This condition is particularly relevant in the context of the ankle and foot, where it can significantly impact mobility and overall function.

Clinical Description

Definition

Varus deformity is defined as a condition where the distal part of a limb is angled inward relative to the proximal part. In the case of the ankle, this results in the foot being positioned in a way that the sole faces inward, which can lead to an abnormal gait and increased stress on the joints and soft tissues of the foot and ankle[1][2].

Etiology

The causes of varus deformity can be varied and may include:
- Congenital Factors: Some individuals may be born with structural abnormalities that predispose them to varus deformities.
- Acquired Conditions: These can arise from trauma, arthritis, or other degenerative diseases that affect the alignment of the bones and joints[3].
- Neuromuscular Disorders: Conditions that affect muscle tone and control can also lead to varus deformities as the muscles may not support the bones properly[4].

Symptoms

Patients with varus deformity may experience:
- Pain: Discomfort in the ankle and foot, particularly during weight-bearing activities.
