Bmi and Gender do not Influence Surgical Accuracy during Minimally Invasive Total Hip ArthroplastyVon Roth P, Olivier M, Preininger B, Perka C, Hube R.
We investigated the accuracy of implant positioning during total hip arthroplasty (THA) through a minimally invasive approach in relation to body mass index (BMI) and gender by assessing 48 patients. Functional and radiological parameters were evaluated.
BMI positively correlated with operation time (p=0.04), but BMI and gender had no influence on implant positioning. The Harris hip score (HHS) increased significantly (46.5±11.8 preoperatively, 92.1±9.7 postoperatively, p<0.0001).
The surgical approach described resulted in reproducibility of implant positioning independent of influence by BMI or gender.
