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., conditionsModule conditions: Orthopedic Surgery, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: PARALLEL, primaryPurpose: TREATMENT, maskingInfo masking: SINGLE, whoMasked: PARTICIPANT, enrollmentInfo count: 44, type: ESTIMATED, armsInterventionsModule interventions name: magnetic resonance neurography, interventions name: no magnetic resonance neurography, outcomesModule primaryOutcomes measure: Hip joint outcome score(HOS) scale, primaryOutcomes measure: Objective hip function scoring scale, secondaryOutcomes measure: Hip joint function of patients, secondaryOutcomes measure: Imaging data of patients with gluteal muscle contracture, secondaryOutcomes measure: Record the duration of the patient 's surgery, secondaryOutcomes measure: The record of the length of the surgical incision of the patient, secondaryOutcomes measure: Measurement of intraoperative blood loss, secondaryOutcomes measure: The first ambulation time after operation, secondaryOutcomes measure: postoperative pain score, secondaryOutcomes measure: Postoperative patients were satisfied with the appearance, secondaryOutcomes measure: The record of postoperative wound infection, secondaryOutcomes measure: The occurrence of postoperative wound fat liquefaction, secondaryOutcomes measure: Postoperative wound peripheral nerve vascular injury, secondaryOutcomes measure: Postoperative incision hematoma formation, otherOutcomes measure: Gluteal muscle contracture severity ZHAO 's classification, otherOutcomes measure: Demographic characteristics of patients, eligibilityModule sex: ALL, minimumAge: 18 Years, maximumAge: 65 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: Xijing Hospital, the Fourth Military Medical University, status: RECRUITING, city: Xian, state: Shaanxi, zip: 710032, country: China, contacts name: Xiang He, MS, role: CONTACT, phone: 8684771013, email: caruya@163.com, contacts name: Long Bi, Prof., role: CONTACT, phone: 8684771013, email: bilong@fmmu.edu.cn, contacts name: Long Bi, Prof., role: PRINCIPAL_INVESTIGATOR, geoPoint lat: 34.25833, lon: 108.92861, hasResults: False
