Precision Resection in Heterotopic Ossification with Customized 3D Solutions

Patient-specific drilling jig planned from CT and MRI to avoid vessel and nerve injury

Patient-specific drilling jig for heterotopic ossification

Patient overview

A 40-year-old male presented with bilateral heterotopic ossification in the lower limbs, requiring surgical removal of the heterotopic bone masses. The procedure demanded a highly precise approach to avoid vessel and neurological injury.

Surgical planning

Collaborating with Dr. Chetan Sood, Jajal Medical meticulously planned the surgery. The process involved segmenting a 3D model of the hip joint from CT scans and mapping blood vessels from MRI scans.

This detailed virtual planning was critical in identifying precise resection sites and mitigating surgical risks.

3D-printed, patient-specific jigs

Jajal Medical provided a patient-specific drilling jig, designed from the 3D models created from the patient’s scans. The jig was tailored to guide precise perforations at the resection sites, minimising the risk of damaging critical vessels and nerves during surgery.

Manufactured in biocompatible and autoclavable medical-grade plastic, the jig ensured both accuracy and durability, aligning perfectly with the patient’s unique anatomy.

Post-op outcome

The postoperative results were outstanding, with the patient experiencing significant recovery. A video demonstrating the intraoperative procedure and surgeon feedback emphasised the success of the femur cutting guide and preoperative planning.

Dr. Chetan Sood described the patient-specific jig and detailed planning as “real game changers”, highlighting their role in the surgery’s precision and safety. The patient reported marked improvement in mobility and quality of life following the operation.
