Precision Reconstruction of Humerus with Customized Implant Solution

Patient overview

A 10-year-old boy presented with a tumour in the humerus bone, affecting the joint and relevant motion. Surgical intervention required the removal of the tumour-affected bone and reconstruction of the humerus with a custom prosthesis.

Surgical planning

A customised humerus implant was designed and developed to ensure precision and functionality, incorporating innovative features tailored to the patient’s unique requirements. Cutting guides were provided to achieve precise resection during surgery.

• A lightweight cage structure in the middle shaft to reduce weight while maintaining strength
• Porous structure at the preserved bone contact points for optimal bone integration
• Locking screws to ensure stable fixation during and after surgery
• A mirror-polished spherical head to restore shoulder joint articulation
• Suture holes for ligament and muscle attachment, facilitating restoration of functionality

3D-printed, patient-specific solution

The implant was manufactured using metal 3D printing technology in biocompatible titanium grade 5, ensuring durability and compatibility with the body. Cutting guides were created using BioMed Amber material, allowing for precise and efficient resection of the affected bone.

Post-op outcome

The implant was fixed perfectly into the patient’s body, providing a stable and functional reconstruction of the humerus. The patient experienced significant improvement in joint mobility and limb function post-surgery.

This case highlighted the critical role of customised prosthetic solutions and advanced 3D printing technologies in achieving life-changing outcomes for young patients.
