Objective:
To explore the feasibility of full endoscopic fenestration (FE-FE) via interlaminar approach for the treatment of lumbar spinal stenosis (LSS), and meanwhile, to analyze the related practicability and clinical outcome.
Methods:
Referring to the traditional laminectomy and decompression, the lumbar spinal canal decompression was performed by using the water-medium spinal endoscopy (named FE-FE technique). Thirty-seven patients with LSS treated by FE-FE technique were retrospectively analyzed. There were 19 males and 18 females, aged from 55 to 83 years old with an average of (67.1±18.9) years. Visual analogue scale(VAS), Japanese Orthopaedic Association Scores(JOA), Oswestry Disability Index (ODI) and 36-Item Short-Form Health Survey (SF-36) were recorded. The patient's conscious pain and recovery of neurological function were observed, and the clinical efficacy was evaluated according to the improvement rate of JOA score.
Results:
All 37 patients were followed up for 8 to 24 months with an average of (13.7±6.1) months. The postoperative follow-up and clinical evaluation for conscious pain and neurological function recovery showed that VAS, JOA, ODI and SF-36 scores were significantly improved compared with those before surgery(P<0.05). According to the improvement rate of JOA score to evaluate the clinical effects, at 6 months after opertion, the results were excellent in 17 cases, good in 13 cases, fair in 5 cases, and poor in 2 cases;and the last follow-up, the results were excellent in 19 cases, good in 13 cases, fair in 4 cases, and poor in 1 case. Postoperative imaging showed significant expansion of spine canal volume, and the followed-up clinical symptoms were improved satisfactorily, with the relief of lumbago and leg pain, improvement of daily life quality, and increased adaptability to social activities and no serious complications.
Conclusions:
Precise localization is the key to complete the canal decompression under full endoscopic surgery. FE-FE technique can effectively enlarge the narrow lumbar canal with less trauma, positive efficacy, safety and reliability. FE-FE has a broad application prospect though large cases and multi-center studies need to be further carried out.
