What is congenital tibial pseudarthrosis?

Anterolateral Bowing and Congenital Pseudoarthrosis of the tibia are conditions present from birth and can be associated with Neurofibromatosis Type 1. With these conditions patients see an increased risk of fracture, or fractures that develop as a result of minor injury. Patients with this condition see a lateral, curved appearance in the tibial bone that is usually apparent within the first two years of life. Though conservative treatments such as bracing may help the condition, they do not stop its progression.


The cause for Congenital Pseudoarthrosis of the Tibia is not known. It may involve a lack of blood supply to the outer layer of bone that promote healing after a fracture.


  • Imbalance in leg lengths or arm length
  • Pain in joints due to limping
  • Decreased range of motion
  • Loss of function of the affected body part
  • Sometimes a visual deformity or length difference can be seen


Understanding the underlying causes and properly diagnosing your condition is the first step to treatment. We then provide a holistic approach to helping patients and their families through their surgical journey. Properly supporting you and/or your child, while educating you on the details helps us ensure the most successful outcomes possible. Our hands on, team approach makes patients feel supported throughout the whole treatment process.

To learn more about your condition and receive a diagnosis, schedule a virtual consultation with one of our experienced orthopedic doctors. During this consultation, all your questions will be answered as our specialists guide you through the evaluation process.

Conservative Treatment

  • Bracing until there is the first fracture
  • Bracing following any surgical correction

Surgical Treatment

The goal of surgery is to get the tibia to heal and remain healed throughout childhood. Typically this involves fixation internally and externally with different types of bone grafting procedures. Once the tibia is healed, patients are followed with bracing.
