Enchondroma Resection & Allograft Reconstruction​

Case Summary:
Enchondroma Resection & Allograft Reconstruction​ Surgical Guides

Patient Diagnosis:

The female patient presented with a distal femoral enchondroma.

Planned Procedure/Approach:

A resection of the enchondroma using a shark bite technique via a medial subvastus approach, curved osteotomy and patient matched femoral allograft for reconstruction.

The curved resection enabled the surgeon to remove the minimum amount of healthy bone possible and also reduced the likelihood of stress concentrations which might have led to fracture of the reconstruction.

What Insight Surgery provided:

• Patient-specific 3D segmented model of the patient’s femur
• Virtual surgical plan
• Two Surgical Cutting Guides for resection
• One Surgical Drilling Guide
• Allograft Cutting Guides with cradle to match the resected segment with compression fit

Outcome/Benefits:

• Predetermined drilling depths helped to simplify this stage of the highly complex procedure, thereby reducing the surgical stress, and was greatly appreciated by the surgeon intraoperatively
• The implanted allograft segment docked tightly into the patient suggesting good stability and compression.
• The interface at the allograft-bone interface ran congruently when viewed on the intraoperative x-rays, further supporting this stable fixation​
