Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0036] see figure 1 , figure 2 , image 3 and Figure 8 , Figure 9 According to the surgical characteristics of total sacral resection, combined with the anatomical structure characteristics of the pelvic ring, the present invention proposes a 3D printed personalized titanium alloy prosthesis that can fix the lumbar spine and bilateral ilium.
[0037] The above-mentioned 3D printed individualized titanium alloy prosthesis includes a lumbar joint 1 in contact with the lower endplate of the lumbar vertebra 11 (specifically, the lumbar 5 vertebral body) and an iliac joint 2 in contact with the remaining ilium 10. The lumbar joint 1 There is a hollow connecting part 3 that adapts to the anatomical shape between the side of the lumbar joint and the ilium joint 2 on both sides; the middle part of the back side of the lumbar joint 1 has a bone ...
