Brief Summary

Total hip replacement is one of the most common surgical procedure in France. In 2010, an estimated 147 513 total hip procedures were performed. This number is constantly increasing. Although it is common, it can lead to many complications. The intra-prosthetic luxation is the second one after aseptic loosening. The luxation risk is multifactorial and depends on the relative orientation of femoral et acetabular components. This orientation is influenced by statics and dynamics parameters. So far, the literature shows that only static parameters are considered by surgeons. Thus, in reference to Lewinneck publication, which states that the luxation risk is lower if the cup is oriented with 15° +/- 10° of anteversion and 40°+/- 10° of inclination with respect to the anterior pelvic plan (APP). Defined by the two anterosuperior iliacs spines and pubic symphysis. However, this approach is only static and do not take into account the variations of pelvic plan orientation during everyday life. To consider these variations of pelvic inclination, it is possible to measure the angle between APP and the horizontal (in lying position) or the vertical (in standing position) plan. Several devices allow the measure of pelvic inclination but they all have important limits (EOS radiography, scanner or navigation). A new device has been developed in Brest to measure this inclination in several positions of the daily life.This software has already been tested in healthy volunteers and results demonstrate an excellent accuracy and reproducibility. The goal of this study is to described the dynamic of the pelvic bone thanks to this ultrasound based device, and to assess the amount of variation induced by hip replacement procedures.

Outcome Measures

Primary Outcomes (1)

  • Variation of the pelvic incidence

    The main evaluation criterion is the variation of the pelvic incidence between pre- and post-operative total hip replacements

    Day 0 - Month 3

Secondary Outcomes (4)

  • Analysis of the correlation between the variation in pelvic incidence while sitting, standing and lying down and the implant settings

    Day 0 - Month 3

  • Analysis of the correlation between variation in pelvic incidence while sitting, standing and lying down and clinical parameters (Harris hip score)

    Day 0 - Month 3

  • Analysis of the correlation between variation in pelvic incidence while sitting, standing and lying down and clinical parameters (EVA)

    Day 0 - Month 3

  • Analysis of the correlation between variation in pelvic incidence while sitting, standing and lying down and clinical parameters (Hand-ground distance)

    Day 0 - Month 3

Study Arms (1)

Patient

EXPERIMENTAL

All patients will have a clinical examination before surgery and another 3 months after surgery, each including : * A medical examination * 3 pelvic inclination measurements (1 sitting, 1 lying and 1 standing). These measurements will be done by ultrasound devices. * 2 EOS X-rays (1 standing and 1 sitting) of the lower limbs and spine * Harris hip score * Pain quantification thanks to an EVA scale * hand-ground distance

Other: Pelvic inclination measurement

Interventions

Ultra-sound based measurements of the pelvic inclination lying, standing and seating position. EOX X-ray in seating position.
