Clinical application effects of personalized customized bone plates
Improving surgical accuracy: Doctors can intuitively understand the degree and type of fracture injury through 3D models, which is convenient for preoperative surgical planning and helps with fracture reduction during the operation. For instance, by using 3D printing technology to create 1:1 pelvic models and custom steel plates based on preoperative simulations, the operation time and instrument operation time can be reduced, as well as the frequency of intraoperative fluoroscopy and blood loss.
Promoting bone healing: Personalized customized bone plates are highly compatible with the patient’s bone structure, providing long-term and stable support for bone healing, promoting the combination of bone and sutures, and helping patients recover their functions more quickly. If digital 3D printed titanium plates are applied to reconstruct jawbone defects, the occlusal function and facial morphology of postoperative patients will recover well, and the efficiency of bone healing will be significantly improved.
Improving patient prognosis: In some clinical cases, patients treated with personalized custom bone plates have seen a decrease in postoperative pain scores and an increase in joint function scores. For instance, in the treatment of posterior acetabular wall and hip column fractures with 3D printing combined with personalized custom metal plates, the hip joint function and pain scores of the 3D printing group were significantly better at 12 months.
Reduce complications: Personalized custom-made bone plates can reduce postoperative complications caused by poor matching. If 3D-printed individualized guide plates are used to assist total knee arthroplasty, the surgical incision will be smaller, the femoral marrow does not need to be opened, avoiding the destruction of the bone marrow cavity, and the amount of bleeding will also be less, reducing the risk of complications such as infection.
Adapting to complex conditions: For patients with complex fractures or deformities, personalized customized bone plates can better meet the treatment needs. If 3D printed patient-specific bone plates were designed for patients with upper limb deformities, sub-millimeter-level anatomical reduction could be achieved through preoperative CT modeling, mirror projection of the healthy side and other techniques. After the operation, the pain of all patients was significantly relieved and the average DASH score increased.
