Reconstructive Allograft Preparation for Long Bone Intercalary Segments After Tumor Resections: Toronto Sarcoma...

Area of Science:

• Orthopedic Surgery
• Oncology
• Biomaterials Science

Background:

• The Reconstructive Allograft Preparation by Toronto Sarcoma (RAPTORS) protocol is a reliable technique for intercalary allograft reconstruction.
• It addresses common causes of allograft failure, including infection, fracture, and nonunion, without significantly increasing surgical time or cost.

Purpose of the Study:

• To describe the RAPTORS protocol for intercalary allograft preparation.
• To highlight its effectiveness in managing bone defects after tumor resection.

Main Methods:

• Allograft preparation involves debris clearance, medullary canal lavage, pressurized antibiotic-laden cement filling, and cancellous autograft insertion.
• Dual-plate compression is used for fixation, with meticulous attention to preserving allograft integrity and promoting bone healing.

Main Results:

• The RAPTORS protocol has demonstrated high rates of long-term success in intercalary allograft reconstruction.
• Complication rates are lower compared to those reported in existing literature.

Conclusions:

• The RAPTORS protocol is a reproducible and effective method for intercalary allograft reconstruction.
• It offers a reliable solution for bone defects, minimizing complications and achieving durable outcomes.
