Miniincisión en prótesis de cadera: ¿hay evidencia de que mejore los resultados respecto a la incisión estándar?

Objective

To assess whether there is scientific evidence that minimally invasive total hip arthroplasty provides better results than the standard approach.

Material and methods

A review of the literature was performed. Well-designed, prospective studies with a high level of evidence that compared the 2 techniques in terms of aggressiveness, correct component placement, bleeding, early outcomes, midterm results and complications rates were chosen.

Results

Seventy-four articles explicitly analyzed minimally-invasive hip arthroplasty but only 10 were comparative studies providing a high level of evidence.

Discussion

There are few well-designed studies that compare the results of minimally invasive total hip arthroplasty with those of standard techniques. Most of these articles found no significant differences in any of the factors evaluated to indicate the superiority of one or other technique.
