Chondrosarcoma Resection & Hemipelvectomy​

Case Summary:
Osteosarcoma Resection & Hemipelvectomy​ Surgical Guide

Patient Diagnosis:

This patient was diagnosed with a chondrosarcoma of the left pelvis.

Planned Procedure/Approach:

A P2/P3 and partial P1 hemipelvectomy resection was planned to remove the affected part of the hemipelvis, whilst maximizing bone preservation, in particular the iliac crest.

What Insight Surgery provided:

• Patient specific 3D virtual models using a combination of CT and MRI scans
• Virtual Surgical Plan – Two different tumour margins, wider anteriorly and narrower posteriorly, were agreed with the surgeon and used to set the resection plane locations and angles.
• Surgical guides
• 3D printed anatomical models
• Rapid turnaround

Outcome/Benefits:

• The procedure was completed quickly and successfully in 90 minutes
• Using the narrower margin posteriorly helped the surgeon to avoid critical neurovascular structures at the sciatic notch and preserve as much bone as possible for reconstruction.
• Negative margins were achieved and this successful resection enabled to surgeon to plan a future surgery to reconstruct the affected anatomy with a custom implant
