The invention relates to a total
sacrum artificial
prosthesis. The total
sacrum artificial
prosthesis comprises a
coloboma body connected among the
bone cutting end of a
lumbar vertebral body, the
bone cutting end of a left ilium and the
bone cutting end of a right ilium, the
coloboma body is provided with three contact faces, the contact face making contact with the bone
cutting end of the
lumbar vertebral body is a
vertebral body contact face, the contact face making contact with the bone
cutting end of the left ilium is a left ilium contact face, the contact face making contact with the bone
cutting end of the right ilium is a right ilium contact face, and the vertebral
body contact face, the left ilium contact face and the right ilium contact face are all of a porous structure; a hollow inverted-Y-shaped
soft tissue adhering part is formed among the vertebral
body contact face of the
coloboma body, the bone cutting face of the left ilium and the bone cutting face of the right iliumm, and the
soft tissue adhering part is also of a porous structure; the coloboma body is further provided with a plurality of fixing holes, and the coloboma body is fixed among the bone cutting end of the
lumbar vertebral body, the bone cutting end of the left ilium and the bone cutting end of the right ilium through fixing elements. The inverted-Y-shaped design closest to the
human body bone structure is adopted, reconstruction of the three aspects of the
waist-the ilium, a posterior
pelvic ring and anterior vertebrae fusion can be achieved, triangular supporting is achieve so that the most stable mechanical environment can be achieved,
bone fusion can be achieved, and remarkable improvement can be achieved in the aspects of recent structure restoration and functions and living quality of patients in the future.
