Osteoid osteoma of the femoral neck in a child. A male patient, eight years and five months old, reported pain in his right hip for five months. Radiographs of the hip showed a sclerotic lesion with a central niche in the right femoral neck. (Figures 1 to 4).
Osteoid Osteoma of the Femoral Neck in a Child – Management – Planning – Resection and reconstruction techniques with autologous graft
Bone scintigraphy revealed the presence of a single image, with intense uptake in the colon. (Figures 5 to 7).
For surgical planning, in the radioscopy room, under anesthesia, the femoral neck is located and a small hole is made in the cortex, closest to the center of the niche, performing controls in the profile and front (Figures 8 a 11).
After marking, a tomography is performed to calculate, to the millimeter, the distance from the hole made to the center of the lesion (Figures 12 and 13).
This bone defect represents more than 25% of the femoral neck and can take around three years to repair. In this location, the risk of neck fracture is very high and we must be careful and reconstruct the failure with an autologous graft, preferably.
Osteoid osteoma is a benign bone neoplasm that, when resected en bloc, heals the lesion, without the need for any other complementary treatment. In places with a high risk of fracture, such as the femoral neck, reconstruction with an autologous graft is imperative to allow the anatomical restitution of the joint, enabling normal hip function.
