The hip is frequently assigned to osteomas which resection can be challenging given the complexity of the region. 3D printing affords a better visualization of complex ossifications to better define its limits and minimize morbidity.
The main purpose of our study is to report the use of 3D model printing in the preoperative planning of hip osteoma resection by reporting our case.

Methods
We relied on a preoperative CT scan of the pelvis to reconstruct a 3D model of the osteoma within the bone with the collaboration of an engineer. Images were obtained with a slice thickness of 1 mm using DICOM. We studied the limits of resection.
The models were designed on the computer by the engineer and printed using the Ultimaker 5 bundle. We evaluated the patient’s complaints, preoperative X-ray and CT scan. Functional results included pain, walking, work and hip ROM.

Results
A case of a 25 year-old female with a medical history of severe brain injury after a road traffic accident with a ICU stay of 4 months. The patient had arthrolysis of the hips. An intertrochanteric fracture occurred peroperatively that healed in vicious callus. presented with giant osteomas of the hip. The patient suffered from a giant painful mass of the right/left hip since 2021 and stiffness with no improvement with medical treatment. Plain pelvic AP radiograph and CT-scan showed giant osteoma of both hips of 8 cm. Preoperative planning consisted of preparing a Patient-Specific Guide using a 3D model. It took 180 minutes to print the model and 90 minutes for the patient-specific guide. This delay didn’t extend the surgical delay given that patients were given two to three weeks to prepare the preanesthetic evaluation.
The patient has a resection of the left osteoma with a total hip arthroplasty followed by a resection of the right osteoma with arthroplasty. Blood loss was 2 g/dl.

Conclusion
The 3D model printing guided the surgeon to perform a safe and rapid removal of hip osteoma. When well-commanded, it facilitates the surgical procedure and may reduce morbidity related to blood loss and operative time.
