Introduction:

Tibial hemimelia is a rare entity, reported in up to 1:1,000,000 live births. It has an autosomal recessive genetic association, and it presents with changes in the morphology of the lower limb with an absent or partially present tibia, as well as changes in the fibula, knee, and foot. Depending on its classification, it can be managed with surgical reconstruction of the limb or amputation. The possibility of an early prosthesis favors the functional result of the patient and his prosthetic adaptation.

Objective:

To report the case of a rare entity treated with knee disarticulation and prosthesis due to its degree of compromise.

Case report:

The case of a three-year-old female patient with compromise of the lower right limb is reported here. The first years she used a handmade prosthesis made by her family. She was assessed by the Medical Board of Rehabilitation and Orthopedics, which decided to undergo surgery for knee disarticulation. Early fittings were performed in search of healing benefits, edema control and post-surgical adaptation. Subsequent controls were carried out with adjustments to the prosthesis according to the needs of the patient's age.

Conclusions:

An adequate post-surgical evolution is shown, without pain or neuropathy, with early resumption of gait and adequate progress of their neurodevelopment and social integration, which provides recommendation for management in pediatric patients with this type of deformity.
