Bone osteotomy surface, ischium osteotomy surface and pubis osteotomy face bonding, the second network 61 is similar with human body trabecular bone structure, with a thickness of
2-3mm can achieve the requirement that bone trabecula is grown into, to realize the Periacetabular borrowed structure of the present embodiment hyperpelvic remote
The effect that phase is fixed.
The surface of metal bone trabecula plate 60 on ilium supporter 20 is ilium side seam contact surface, on ischium supporter 30
The surface of metal bone trabecula plate 60 is ischium side seam contact surface, and the surface of the metal bone trabecula plate 60 on pubis supporter 40 is shame
Bone side seam contact surface；The position of ilium side seam contact surface and tilt angle determine by Iliac osteotomy face, ischium side seam contact surface
Position and tilt angle are determined that the position of pubis side seam contact surface and tilt angle are determined by pubis osteotomy surface by ischium osteotomy surface
It is fixed.
In specific surgical procedure, the top rake and valgus angle of acetabular cup 10 are required by doctor according to sufferer feature-set,
Preferably guarantee that Periacetabular borrowed structure is not dislocated.On the first screw hole 23, the second screw pole 31 on first screw pole 21
The second screw hole 33 and third screw pole 41 on third screw hole 43 during surgery as needed selection using therein
Several, play the primary stability for guaranteeing Periacetabular borrowed structure.
Preoperative, hospital acquires patient CT data, and engineer handles and analyze data, formulates operation plan, is carried out by doctor
Confirmation especially determines pelvis ilium side, ischium side, the osteotomy site of pubis side and angle, then engineers design's osteotomy institute
Need pelvic osteotomy guide plate and the present embodiment Periacetabular borrowed structure, after doctor confirms, using 3D printing technique into
The Periacetabular prosthese and its die trial of the corresponding pelvic osteotomy guide plate of row production and the present embodiment are simultaneously adequately post-processed.
Doctor needs to carry out preoperative model surgery before formal operation carries out, using pelvic osteotomy guide plate, the present embodiment
The die trial of Periacetabular borrowed structure and pelvis model carry out simulation osteotomy and mould Periacetabular borrowed structure installation.
In art, doctor uses conventional surgical techniques, handles acetabular bone side, pelvic osteotomy guide plate is then mounted on bone
The corresponding position of basin, stamps fixing glue, carries out osteotomy along Iliac osteotomy face, ischium osteotomy surface, pubis osteotomy surface.
After the completion of osteotomy, the Periacetabular borrowed structure die trial of the present embodiment is mounted on defect location, specifically, is such as schemed
Shown in 4, by the Iliac osteotomy of the ilium side seam contact surface of Periacetabular borrowed structure and ilium 70 in face of together, ischium side seam is connect
Contacting surface is aligned with the ischium osteotomy surface of ischium 80, and pubis side seam contact surface is aligned with the pubis osteotomy surface of pubis 90, then right
Periacetabular borrowed structure die trial installation site situation is confirmed.
Confirm it is errorless after, Periacetabular borrowed structure is mounted on by defect point using identical method, confirms installation site
After errorless, the first screw hole 23, position suitable in the second screw hole 33 and third screw hole 43 are selected according to situation in art
Several screw holes are squeezed into corresponding screw respectively and are screwed in cancellous bone.Guarantee Iliac osteotomy face, ischium osteotomy surface and shame
The each position of bone osteotomy surface at least one piece of screw is screwed into and fixes.
After Periacetabular borrowed structure is fixed by corresponding screw, the bone cement of 2mm thickness is packed into acetabular cup 10,
It is then charged into cement mortar cup, after bone cement solidification, then acetabular bone replacement operation is completed.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
