Abstract
Objective To evaluate the efficacy and safety of percutaneous tenotomy of the iliopsoas muscle
tendon guided by ultrasound (US) in cadavers.
Methods We conducted an anatomical and descriptive study of the US-guided percutaneous tenotomy
technique for the iliopsoas muscle tendon to review our experience performing it and
its reproducibility in the clinical practice.
Results Of the 20 tenotomies, 17 were total, at the level of the upper edge of the acetabulum,
while 3 were partial. One procedure resulted in a partial injury to the femoral nerve.
We measured the distance between the place of blade introduction and the femoral nerve,
a noble structure potentially at a higher risk during the procedure; the mean distance
was of 8.4 mm.
Conclusion Iliopsoas tendon release procedures guided by US in a cadaveric model are feasible
and consistently result in the total release of the tendon, except in cases of obesity,
with minimal repercussions on adjacent structures, and their completion requires approximately
4 minutes.
