Randomized trial demonstrates effective nerve root decompression in patients with cervical radiculopathy, suggesting benefits of a minimally invasive technique.
Key Points
To evaluate the safety and efficacy of biportal endoscopic cervical foraminotomy for decompression of nerve roots in patients with isolated unilateral cervical radiculopathy.
Performed in a prone position using routine neuromonitoring and intraoperative fluoroscopy.
Two paramedian incisions are made to establish working and viewing portals for endoscopic visualization.
Sequential dilators and high-speed instruments are used for decompression with careful hemostasis management.
87.4% of patients achieved complete resolution of arm pain following biportal endoscopic foraminotomy.
Minimally invasive foraminotomy resulted in reduced blood loss (52.8 mL vs 173.5 mL) and shorter operative duration (58 min vs 108 min).
Clinical outcomes were comparable with traditional microsurgical methods and ACDF, but with significantly shorter hospitalization time.
