Over the past forty years, improvements in bone sarcoma adjuvant therapies have sparked the creation of novel surgical technologies that have improved limb-sparing procedures. Through these technologies, limb salvage surgery has largely replaced amputation as the standard of care. These developments include patient-specific intraoperative instruments and pre-and post-operative imaging technologies. These enable precise 3D preoperative planning. With the advent of 3D-printed porous titanium implants, surgeons have more freedom to preserve surrounding healthy tissue and enhance reconstruction fit. It enhances the patient’s life and lowers postoperative comorbidities. A new era in orthopaedic oncology has begun with the development of these custom implants, which have introduced novel processes, materials, and technologies.
Incredible AM Pvt Ltd, utilizing its high-quality additive manufacturing capability, is able to produce patient-specific implants and tools for patients requiring limb salvage surgery, including revision hip replacement with major cancerous defects. Read below to know the benefits of PSI for hip replacement surgery, but before that, we will learn about the use of 3d printing in hip replacement surgery.
Clinical uses of 3d printing in hip surgeries
Three-dimensional (3D) printing is used more often throughout industries, including orthopaedic surgery. There are now four main clinical uses for 3D printing in hip surgeries:
- 3D-printed anatomical models: The first step is the creation of anatomical models based on patient imaging; these bone models can help with a better understanding of patho-anatomy and can be used by surgeons to mimic operations in order to possibly improve performance.
- Patient-specific instruments (PSI): The second is the creation of patient-specific instruments, most of which are produced as jigs or guides and may improve surgical accuracy.
- Creation of arthroplasty implants: The third is the manufacture of arthroplasty implants; 3D-printed hip implants have an advantage over traditional ones because ingrowth surfaces can be adjusted to maximise bone ingrowth.
- Custom 3D printed prostheses: The creation of bespoke implants comes next. In contrast to standard-sized implants, a custom implant made from medical pictures of the patient may be a perfect fit for the patient’s particular anatomy.
It’s significant to note that 3D-printed bespoke implants have lately been used in challenging revision hip arthroplasty procedures with substantial acetabular bone loss, in addition to pelvic tumour surgery.
Surgeons can improve their surgical techniques, evaluate the viability of treatments, and decide where and how big to place prostheses by simulating surgery on a 3D-printed bone model. During surgery, customized instruments help in guiding precise bone cuts and prosthetic implantation.
Benefits of patient-specific hip reconstruction implants from Incredible, Pune
3D Incredible in Pune has state-of-the-art 3d printing facilities where an experienced and knowledgeable team creates the best patient-specific implants with the most biocompatible material. The patient-specific implants for hip reconstruction have the following benefits
- Specific to the patient’s defect or anatomy, it provides an excellent fit.
- Customization in accordance with surgeons’ needs.
- Varying thickness according to the needs of the surgeon.
- To ensure strength, stability, and functionality, each design must undergo finite element analysis.
- Biomechanically appropriate lattice structures are used to achieve desired porosity, improved osteointegration, and better control of weight.
Patient-specific screw specifications:
- Selection of the screw’s location based on need.
- Each screw might have a different diameter.
- Locking holes, cortical holes, compression holes, and other combinations of those holes.
- Every hole’s predetermined trajectory provides prolonged stability.
Conclusion
At Incredible 3D, we think every patient is significant and deserves unique consideration. In order to support a surgeon in treating the patient in the best possible ways, we offer services and implants that are patient-specific.
The newest manufacturing technology, metal 3D printing, has the potential to completely change the way metal parts are currently produced. Without using tools, it is capable of creating extremely elaborate and complicated shapes. We manufacture parts using a “Near Net Shape” method, which achieves a 0.2 mm accuracy in building them very near to the required dimensions.
To obtain 3d-printed anatomical models, customized implants and instruments, etc. connect with us.
