Summary

The ilio-psoas conflict is a commonly accepted complication after total hip replacement, often linked to a mispositioning of the acetabular prosthetic component that conflicts with the ilio-psoas tendon. To correct these pains, a psoas tenotomy can be proposed. The results proven by the literature are very satisfactory. Psoas tenotomy is performed endoscopically, arthroscopically, or more rarely open. The contribution of echo surgery allows to limit the scar ransom but also to free itself from a complex infrastructure to the operating room including an arthroscopy column and an intraoperative fluoroscopy for a conventional tenotomy, This also saves procedural and installation time. No studies to date have described ultrasound-assisted psoas tenotomy Yhe investigators conducted a cadaveric study of the feasibility of psoas tenotomy under ultrasound that confirms the feasibility of this technique and the safety of the gesture for the surrounding anatomical structures. The objectives of this study are to assess the feasibility, pain and functional outcomes of ultrasound-assisted psoas tenotomy in patients with ilio-psoas conflict after total hip replacement.

• Hip Injuries

Interventions

Type	Name	Description
PROCEDURE	Psoas tenotomy under ultrasound	Tenotomy of the ilio-psoas tendon under ultrasound is performed using an ultrasound machine, a 3 mm Acufex hook blade and a specific kit usually used for guided vertebroplasty and which allows the introduction of the Acufex hook blade atraumatically (foam end). The patient, under general anesthesia, is placed in supine position with the hip extending from 15 to 20°.
