The posterior approach is the most commonly used surgical approach by orthopedic surgeons internationally when doing a total hip arthroplasty. (1,2,3) It was first popularized by Moore in the 1950’s, and has been gaining popularity ever since. (1)
One of the advantages to using the posterior approach for a total hip arthroplasty is that it allows the surgeon to have decent exposure of both the femur and acetabulum during the procedure. The patient is placed in the lateral decubitus position on an orthopedic table to improve visualization and accessibility of the hipbone as well as aid in dislocating the hip bone. The skin incision can be made in several different ways. One way is that it can begin 5 cm distal and continue proximal to the …show more content…
They concluded that there was statistical significance within the Harris Hip Scores (p =.0344), the Harris Hip Function score ( p = .0035), as well as the Trendelenberg Test ( p = < .001 respectively). In result, when it comes to fluoroscopy, Ji and Stewart would say that it achieves better intra-operative assessment of cup orientation as well as decreased variability of acetabular cup anteversions when used in the anterior approach rather than the posterior (5). A study by Rathod and colleagues also looked at the use of fluoroscopy and wanted to see if it decreased acetabular cup variability when compared to a =\]]\[1`[`non-guided posterior approach. They found that the variances for cup inclination and anteversions were much lower in the direct anterior approach (DAA) (19 and 16, p <.01) while the posterior approach had (50 and 70). The target inclination and anteversions were achieved more successfully within the DAA group (98% and 97%) where as in the posterior group ( 86% and 77%). They also concluded that the use of fluoroscopy in the DAA enabled intraoperative assessment of cup orientation. This led to decreased variability of acetabular cup anteversion
