Minimally invasive surgery for gluteal muscle contracture using MRI guidance

Evaluation of the Effect of Percutaneous Minimally Invasive Technique Assisted by Magnetic Resonance Neurography in the Treatment of Gluteal Muscle Contracture

This study is testing if using MRI guidance during minimally invasive surgery can help people with moderate to severe gluteal muscle contracture recover better than standard surgery.

What this trial studies

This clinical trial aims to compare the effectiveness of minimally invasive surgery guided by magnetic resonance neurography (MRN) against a standard minimally invasive approach in patients suffering from moderate to severe gluteal muscle contracture. Participants will be randomly assigned to either the MRN-assisted group, where surgical approaches are tailored based on preoperative MRN findings, or the control group, where MRN is used solely for diagnosis. The study will include 22 cases in total, with assessments made based on imaging and clinical evaluations. The goal is to determine if MRN can optimize surgical outcomes for these patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 with moderate to severe gluteal muscle contracture who have not responded to conservative treatments.

Not a fit: Patients with spinal or lower extremity neurological diseases, hip dysplasia, or those unable to undergo surgery will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved surgical outcomes and recovery for patients with gluteal muscle contracture.

How similar studies have performed: While the use of MRN in surgical planning is gaining interest, this specific application in gluteal muscle contracture is novel and has not been extensively tested in prior studies.
