the Effect of Minimally Invasive Technique Assisted by Magnetic Resonance Neurography
The goal of this clinical trial is to to compare the therapeutic effect of minimally invasive surgery guided by magnetic resonance neurography(MRN) compared with non-magnetic resonance assisted minimally invasive surgery in patients with moderate to severe gluteal muscle contracture(GMC). The main question it aims to answer are: magnetic resonance neurography can better help optimize the surgical path of minimally invasive surgery in the treatment of gluteal muscle contracture.

Participants will underwent preoperative magnetic resonance examination according to different groups, and then the experimental group designed individualized surgical approach and MRN-assisted minimally invasive release according to the imaging findings. In the control group, preoperative magnetic resonance examination was only used to assist in the diagnosis and evaluation of gluteal muscle contracture, and the magnetic resonance results were not used to assist in the design of surgical approach. In the control group, non-MRN-assisted minimally invasive release was performed. The researchers will compare the intraoperative surgery-related indicators and postoperative hip function scores and complications of patients in different groups to see if magnetic resonance-assisted surgery has a better postoperative effect.
