Innovative Limb-Sparing Solution for Bone Tumor Patients
Custom-made prostheses have emerged as an advanced solution for limb-sparing surgeries in patients with bone tumors. Depending on the patient’s condition, custom prostheses can be the optimal choice for limb reconstruction compared to conventional methods such as allografts.
As demonstrated in the animation below, a patient with chondrosarcoma affecting the right pelvis was referred to Jarrah Yar Sharif Company for the design and production of a custom hip prosthesis. Using MRI imaging, precise bone resection points on the pubis and ischium were identified. The tumor extended to the SI Joint, necessitating comprehensive reconstruction. All features of the prosthesis were designed and implemented based on the surgeon’s specifications, and the prosthesis was manufactured using titanium.
Key Features of the Prosthesis:
- Porous Structure: Facilitates cell growth, adhesion, and osseointegration.
- Customizable Screw Placement: Allows for flexibility in the number, position, and direction of screws based on the surgeon’s treatment plan.
- Anatomically Adjusted Cup Angles: Designed in accordance with patient anatomy and surgeon input.
- Additional Fixation Options: Provides enhanced stability for the prosthesis if required.
To ensure precise bone resections, custom surgical guides were designed and applied, tailored to the tumor’s position and the patient’s bone anatomy. These guides enabled accurate placement of the prosthesis, ensuring optimal surgical outcomes.
