This study investigates the effects of gluteal sling release during total hip arthroplasty (THA) on gluteal muscle function and hip joint performance. The gluteal sling release technique is used to improve surgical visualization and reduce the risk of sciatic nerve compression, but its impact on postoperative muscle function remains unclear. A prospective randomized controlled trial was conducted on 144 patients with unilateral coxarthrosis undergoing THA, divided into three groups: gluteal sling preserved, released, and released with repair. Clinical outcomes were assessed preoperatively and at six months postoperatively using VAS, HHS, and WOMAC scores, alongside hip CT scans and isokinetic strength testing. While all groups showed significant functional improvement, muscle density in the released gluteal sling group decreased significantly, suggesting potential fatty degeneration. However, no significant differences were found in gluteus maximus surface area or hip extensor strength between the groups. The findings suggest that while gluteal sling release enhances intraoperative visualization and may reduce sciatic nerve injury risk, it could contribute to muscle degeneration. Therefore, preserving or repairing the sling when possible and implementing structured rehabilitation may optimize postoperative outcomes.

Standard treatment options for patients who are diagnosed with BVFP include tracheostomy, cordotomy, arytenoidectomy, and suture tie-back. These standard treatment options may result in permanent damage to the vocal fold, therefore affecting the patient's ability to speak and compromising airway protection during swallowing. Additionally, these routine procedures cannot provide sufficient airway to permit significant aerobic activity. The goal in conducting this early feasibility study is to investigate the use of this device as a laryngeal pacemaker to treat BVFP.
