ICD-10: Q66.211

Congenital metatarsus primus varus, specifically coded as Q66.211 in the ICD-10 classification, refers to a congenital deformity affecting the foot. This condition is characterized by a lateral deviation of the first metatarsal bone, which can lead to a range of functional and aesthetic issues in the affected foot.

Clinical Description

Definition

Congenital metatarsus primus varus is a condition where the first metatarsal (the long bone in the foot that supports the big toe) is angled towards the midline of the body. This results in a foot that appears to have a curved or "bowed" appearance, particularly noticeable when viewing the foot from above. The condition is typically present at birth and can vary in severity.

Etiology

The exact cause of congenital metatarsus primus varus is not fully understood, but it is believed to arise from a combination of genetic and environmental factors during fetal development. It may occur in isolation or as part of other congenital foot deformities.

Symptoms

Patients with congenital metatarsus primus varus may exhibit:
- A noticeable lateral deviation of the first metatarsal.
- Difficulty in wearing shoes due to the altered foot shape.
- Potential for associated conditions, such as bunions or other foot deformities, if left untreated.

Diagnosis

Diagnosis is primarily clinical, based on physical examination and observation of the foot's alignment. Imaging studies, such as X-rays, may be utilized to assess the degree of deformity and to rule out other associated conditions.

Treatment Options

Conservative Management

In many cases, especially when the condition is mild, conservative treatment options may be recommended:
- Footwear Modifications: Using shoes with a wider toe box to accommodate the foot's shape.
