Embodiment Construction

[0015] Referring now to the drawings, in which like reference numerals indicate like elements throughout these drawings, there is shown an acetabular cup placement device comprising a metal horizontal shaft 9 and a metal The vertical shaft 10, the two metal shafts are perpendicular to each other and firmly connected together by the fastener 20, the fastener 20 has two independent knobs 18 and 21, the knob 18 and the knob 21 are used to connect the horizontal bar and The vertical bar remains locked. In addition, said vertical rod 10 is firmly attached to the acetabular cup insert 6 by means of fasteners 18 . The end of impact member 6 will receive acetabular cup implant 12, such as figure 2 , image 3 and Figure 4 As shown, the acetabular cup implant 12 is pressed into the acetabular cavity prepared by the surgeon in the pelvic bone.

[0016] like Figure 4 As shown, a metal horizontal shaft 9 is slidingly attached at one end to a fastener 20 and has on the other end two...

Abstract

Positioning an acetabular cup in a desired optimal alignment in relation to the patients pelvis using conventional fluoroscopic equipment readily available in operating rooms in conjunction with a metallic jig as guide. The device having inclination metallic rods at 45 degrees angle to the cup impactor and anteversion rod situated at a distance from the midline that correspond to the degree of inclination. When said inclination and anteversion shafts are aligned with central anatomical structures such as symphysis pubis and middle of first sacral vertebra will result in correct placement of the acetabular cup at the desired version.

Description

technical field [0001] The present invention relates to orthopedic devices, and more particularly to devices for precise placement of acetabular cups during hip surgery. Background technique [0002] During total hip replacement surgery, an acetabular cup is almost always in place. Accurate placement of the acetabular cup is critical for the implant to function well to produce a successful clinical outcome. If the position of the acetabular cup is abnormal, it can lead to serious complications that lead to an increased risk of dislocation / premature wear of the bearing surface, and the release of polyethylene fragments and particles This can lead to osteolysis and loosening of the acetabular component. Impact is the main source of loosening and metal deposition, where metal fragments cause severe local tumor-like inflammatory reactions. This can eventually lead to extensive revision of the implant. [0003] The orientation of the acetabular cup is defined by the inclinati...
