Clinical Trial Summary

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.


Description:

According to the different surgical intervention methods, the cases finally included in the study were divided into minimally invasive surgery group and MRN-guided minimally invasive surgery group according to the randomization method. It is expected that the number of cases finally included in the study in both groups will be 22 cases. Firstly, the age and sex of the two groups of patients included in the study were recorded respectively, and the moderate and severe classification was carried out according to the Zhao 's classification system. The experimental group and the control group were examined by pelvic X-ray, magnetic resonance and ultrasound before operation. After improving the relevant preoperative examination and excluding surgical contraindications, the intervention measures of the experimental group were to analyze the relationship between the shape of the contracture zone, the distance between the sciatic nerve and the contracture zone, and the external rotation angle according to the preoperative MRN manifestations of the patients, and to design the individualized surgical approach according to the imaging manifestations. MRN-assisted minimally invasive release ; in the control group, preoperative magnetic resonance imaging was only used to assist in the diagnosis and evaluation of gluteal muscle contracture, and the results of magnetic resonance imaging were not used to assist in the design of surgical approach. In the control group, non-MRN-assisted minimally invasive release was performed. For patients, they all underwent magnetic resonance imaging before surgery, and all underwent minimally invasive surgery. However, the design process of the specific surgical approach is not clear, so it is a single-blind design for patients. All the operations were completed by two senior doctors of our research group. The data of postoperative follow-up were recorded, and the conclusion was drawn by statistical analysis. Intraoperative research indicators include : incision length, operation duration, intraoperative blood loss, first time to get out of bed, pain score, etc. Postoperative follow-up study indicators included : subjective and objective functional rating scales ( hip flexion and adduction activity, leg squat, cross-leg test, Ober sign, pain in activity, claudication in walking ), patient appearance satisfaction, complications ( wound infection, fat liquefaction, neurovascular injury, incision hematoma formation, etc. ).

Outcome

Type Measure Description Time frame Safety issue
Other Gluteal muscle contracture severity ZHAO 's classification The ZHAO 's grading is evaluated by the physician according to the ZHAO 's grading scale. The lowest level of the scale is grade 1, and the highest level is grade 3. The higher the level, the more serious the gluteal muscle contracture is. one day before surgery
Other Demographic characteristics of patients Demographic characteristics of patients one day before surgery
Primary Hip joint outcome score(HOS) scale The hip joint outcome score ( HOS ) was divided into two parts : the activities-of-daily-living ( HOS-ADL ) and sports subscales( HOS-SS ).The lowest score of the scale was 0, and the highest score was 100. The higher the final score, the higher the level of daily life and motor function of hip joint. one week after operation
Primary Objective hip function scoring scale The objective hip function scoring scale is a scale used to objectively evaluate the function of hip joint. The hip joint function of patients is evaluated by doctors and scored one by one according to the items. The lowest score of the scale was 0, and the highest score was 100. The higher the final score, the better the hip joint function. one week after operation
Secondary Hip joint function of patients The patient 's hip function is mainly evaluated by the physician during physical examination. The main indicators include hip flexion and adduction activity, and leg squat, cross-legged test, Ober sign, activity with or without pain, walking with or without claudication. One day before surgery and three days after surgery
Secondary Imaging data of patients with gluteal muscle contracture The imaging data of the patients included the presence or absence of gluteus maximus atrophy, the cumulative range of the contracture zone, the characteristics of the course, and the presence or absence of connection with the iliotibial tract ; the distance between the contracture belt and the sciatic nerve ; external rotation angle of femur. One day before surgery and three days after surgery
Secondary Record the duration of the patient 's surgery Through the operation record, nursing record and the actual situation of the operation, the operation duration of the patients was recorded. The longer the operation duration, the greater the operation risk. During surgery
Secondary The record of the length of the surgical incision of the patient Through the patient 's surgical records and intraoperative actual situation, record the patient 's intraoperative incision length. The greater the length of the incision, the greater the risk of surgery. During surgery
Secondary Measurement of intraoperative blood loss The patient 's intraoperative blood loss was recorded through the patient 's anesthesia records, nursing records, and actual intraoperative conditions. The higher the amount of bleeding, the greater the risk of surgery. During surgery
Secondary The first ambulation time after operation The time when the patient can get out of bed for the first time after surgery, the earlier the time, the smaller the side effects of the patient 's surgery on the patient. The second day after surgery
Secondary postoperative pain score The postoperative pain score of the patient was evaluated by the anesthesiologist. The postoperative pain score of the patient was evaluated by the postoperative anesthesia follow-up record in the medical record system. Minimum 0 points, maximum 100 points. The lower the score, the smaller the surgical trauma. One day after surgery
Secondary Postoperative patients were satisfied with the appearance The patient 's satisfaction with the operation was evaluated by the form of scale score. Minimum 0 points, maximum 100 points. The higher the score, the more satisfied the patient is with the operation. Two weeks after the operation
Secondary The record of postoperative wound infection The record of postoperative wound infection is mainly recorded by the doctor during the postoperative follow-up. The occurrence of infection is a side effect of the operation. Two weeks after the operation
Secondary The occurrence of postoperative wound fat liquefaction Postoperative wound fat liquefaction was mainly recorded by the doctor during postoperative follow-up. The occurrence of wound fat liquefaction was a side effect of surgery. Two weeks after the operation
Secondary Postoperative wound peripheral nerve vascular injury The records of postoperative nerve injury were mainly recorded by doctors during postoperative follow-up. The occurrence of nerve injury is a side effect of surgery. Two weeks after the operation
Secondary Postoperative incision hematoma formation The record of incision hematoma formation after operation is mainly recorded by doctors during postoperative follow-up. The occurrence of incision hematoma formation is a side effect of operation. Two weeks after the operation
