Object The aim of this study was to evaluate whether clinical improvement is noticeable after a minimally invasive procedure such as that used with the Aperius PercLID System in patients with degenerative lumbar spinal stenosis (DLSS) and neurogenic intermittent claudication (NIC). Methods The patients were treated with the aforementioned system at 3 different centers. The initial requirement to be included in the study was a minimum follow-up of 12 months. The authors studied 40 cases of DLSS in patients with NIC (age 72.7 ± 8.08 years). Symptom severity, physical function, quality of life, and self-rated pain were assessed preoperatively and at the 12-month follow-up using the Zurich Claudication Questionnaire (ZCQ) and a visual analog scale. The procedure was conducted under spinal (35 patients) or local (5 patients) anesthesia, using biplanar fluoroscopy for visualization. Results Single-level treatment was performed in 28 patients and 2-level treatment was performed in 12 patients. Based on time recordings in 24 cases, the mean procedural time was 19.9 ± 5.0 minutes. The mean pain visual analog scale score improved significantly from 8.1 ± 2.19 at baseline to 3.44 ± 2.89 at the 1-year follow-up. The ZCQ score for patient satisfaction showed 90% of the patients being satisfied with the procedure. The mean rates of improvement in ZCQ score for symptom severity and physical function at 1 year were 38.7 ± 33.3% and 33.8 ± 29.7%, respectively, and both proved to be statistically significant. Most improvement was seen in mobility, pain/discomfort, and ability for self-care. Conclusions In this preliminary study, the Aperius system provided clinically significant improvement after 1 year of follow-up in patients older than 65 years with DLSS and NIC.

The authors developed an original procedure, modified fenestration with restorative spinoplasty (MFRS) for the treatment of lumbar spinal stenosis. The first step is to cut the spinous process in an L-shape, which is caudally reflected. This procedure allows easy access to the spinal canal, including lateral recesses, and makes it easy to perform a trumpet-style decompression of the nerve roots without violating the facet joints. After the decompression of neural tissues, the spinous process is anatomically restored (spinoplasty). The clinical outcomes at 2 years were evaluated using the Japanese Orthopaedic Association (JOA) scale and patients' satisfaction. Radiological follow-up included radiographs and CT. Between January 2000 and December 2002, 109 patients with neurogenic intermittent claudication with or without mild spondylolisthesis underwent MFRS. Of these, 101 were followed up for at least 2 years (follow-up rate 93%). The average score on the self-administered JOA scale in 89 patients without comorbidity causing gait disturbance improved from 13.3 preoperatively to 22.9 at 2 years' follow-up. Neurogenic intermittent claudication disappeared in all cases. The patients' assessment of treatment satisfaction was “satisfied” in 74 cases, “slightly satisfied” in 12, “slightly dissatisfied” in 2, and “dissatisfied” in 1 case. In 16 cases (18%), a minimum progression of slippage occurred, but no symptomatic instability or recurrent stenosis was observed. Computed tomography showed that the lateral part of the facet joints was well preserved, and the mean residual ratio was 80%. The MFRS technique produces an adequate and safe decompression of the spinal canal, even in patients with narrow and steep facet joints in whom conventional fenestration is technically demanding.

Degenerative lumbar spinal stenosis is a common condition and the most usual indication for spinal surgery in adult patients. The main objective of this study was to investigate clinical outcomes, health-related quality of life (HRQoL) and satisfaction among patients with a diagnosed lumbar spinal stenosis who were surgically treated, and whether these outcomes differed according to gender and age. Surgery was performed on 100 patients with clinical and radiological defined lumbar spinal stenosis. All patients completed questionnaires twice before surgery and at 6 weeks, 12 weeks, and 1 year postoperatively. Main outcomes were symptoms, physical function and patient satisfaction assessed by the Swiss Spinal Stenosis Questionnaire and HRQoL by the Short Form 36 health survey (SF36). There were large improvements in all clinical outcomes and in the physical subscales of the SF36. A marked reduction of average 32.3% was seen in symptoms already at 6 weeks follow-up. Physical function had improved with an average of 29.8% at 1-year follow-up. There was no statistical significant effect of age and gender on symptoms and physical function. Patients more than 65 years were significantly less satisfied at the 1-year follow-up as compared to the younger patients (p=0.012). This study showed that the majority of patients improved significantly in symptoms, physical function and physical HRQoL after surgery for degenerative lumbar spinal stenosis, regardless of age and gender. Age showed to be closely connected to satisfaction.

ABSTRACT OBJECTIVE To evaluate the efficacy of radicular decompression in lumbar spinal stenosis using a microendoscopic technique. METHODS This was a longitudinal prospective study of 50 patients with a diagnosis of lumbar spinal stenosis who were treated by microendoscopic decompression using an 18-mm METRx tubular retractor according to the METRx technique (Medtronic Sofamor Danek, Memphis, TN). Twenty of the patients had an additional disc prolapse, and a microendoscopic discectomy was associated with decompressive laminectomy. The results were evaluated using the visual analog scale pain score, Oswestry Disability Index score, patient satisfaction questionnaire, and modified Macnab classification. RESULTS The average age of the patients was 56 years; 29 (58%) were men and 21 (42%) were women. The most commonly affected level was L4–L5 (64%). The mean surgical intervention time was 94.3 (± 14.3) minutes. Mean postoperative hospital stay was 3.16 (± 2.3) days. The follow-up time after surgery was 4 years (48 ± 6.6 months; range, 24–72 months). We obtained good or excellent results in 72% of patients, achieving good subjective satisfaction in 68% of the patients. The mean decrease in the Oswestry Disability Index score was 30.23 (± 24.29), the mean decrease in the leg pain visual analog scale score was 6.02 (± 2.57), and the mean decrease in the lumbar pain visual analog scale score was 0.84 (± 2.06). Adjusted mean differences were in all cases statistically significant (P <0.05). CONCLUSION Data indicate that, in our experience, on midterm follow-up, microendoscopic laminectomy decompression is an effective technique for the treatment of lumbar spinal stenosis.
