Q66.211 Congenital metatarsus primus varus, right foot

Name of the Condition

• Congenital Metatarsus Primus Varus, Right Foot

Summary

Congenital metatarsus primus varus is a structural foot deformity present at birth characterized by an inward deviation of the first metatarsal bone, affecting the alignment of the forefoot. This condition may impact foot function and gait, potentially leading to discomfort or difficulty with footwear as the child grows.

Causes

The exact cause is not fully understood, but it is believed to involve a combination of genetic factors and disruptions during fetal development. Abnormalities in bone or soft tissue development may contribute to the deformity.

Risk Factors

• Family history of congenital foot deformities
• Intrauterine positioning (e.g., limited space)
• Maternal health conditions during pregnancy

Symptoms

• Visible inward deviation of the first metatarsal at birth
• Altered forefoot alignment
• Potential difficulty fitting standard footwear
• Possible associated gait abnormalities

Diagnosis

Physical examination by a healthcare provider to assess forefoot alignment. Imaging studies (e.g., X-rays) may be used to evaluate bone positioning and rule out other structural abnormalities.

Treatment Options

• Observation for mild cases
• Orthotic devices or bracing to support alignment
• Physical therapy to improve flexibility and strength
• Surgical intervention in severe or persistent cases

Prognosis and Follow-Up

With appropriate intervention, many individuals achieve improved foot alignment and function. Regular follow-up is important to monitor development and adjust treatment as needed.

Complications

• Persistent alignment issues without treatment
• Difficulty with footwear or gait
• Potential secondary musculoskeletal problems

Lifestyle & Prevention

• Regular monitoring of foot development in infants
• Early consultation with a healthcare provider for concerns
• Use of supportive footwear as recommended

When to Seek Professional Help

Seek evaluation if visible foot alignment abnormalities are present at birth or if gait or footwear issues develop. Early assessment is recommended for optimal management.

Tips for Medical Coders

Document the specific laterality (right foot) and confirm the congenital nature of the deformity. Ensure clinical notes support the diagnosis and any associated treatments or evaluations performed.
