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.

Abstract OBJECTIVE The effectiveness and limitations of spinal radiosurgery using a helical TomoTherapy system for the treatment of spinal metastases are reviewed in this article. METHODS This is a retrospective review of patients who underwent stereotactic radiosurgery for spinal metastases between July 2004 and December 2007. Radiographic follow-up consisted of magnetic resonance imaging to assess tumor growth control as well as pre- and posttreatment x-rays, which were used to measure changes in segmental angulation and deformity. Clinical performance was assessed using the Karnofsky Performance Scale, Oswestry Disability Index, and visual analog scale. RESULTS Forty patients were treated for 110 metastatic tumors (range, 1–6 tumors per patient). The mean age at the time of radiosurgical treatment was 67 years (age range, 35–81 years). Twenty-three patients (57.5%) had undergone previous surgical resection. Pain was the most common presenting symptom, seen in 32 patients (80%). The mean Oswestry Disability Index score at presentation was 43 (range, 20–90), and the mean visual analog scale score was 6.2 (range, 0–10). The mean radiosurgical dose to the tumor was 17.3 Gy (range, 10–24 Gy). At a mean follow-up duration of 12.7 months (range, 4–32 months), decreased or stable tumor volume was seen in 90 (82%) of the tumors treated. There was improvement in pain in 34 patients (85%). The mean postradiosurgical Oswestry Disability Index score was 25 (range, 10–90), whereas the postradiosurgical visual analog scale score was 3.2 (range, 0–9). Progression of kyphosis was the most common radiographic sequela, experienced by 73% of patients alive at 12 months, with a mean change in angulation of 7.3 ± 4.5 degrees. CONCLUSION Radiosurgery is effective as either primary or adjunctive treatment of metastatic tumors of the spine.

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.

Abstract Purpose In this prospective study, we aim to determine surgical outcomes in patients with lumbar spinal stenosis (LSS) 10 years after surgery. Methods The study population consisted of 96 LSS patients who underwent decompressive surgery, 72 of whom participated in the 10-year follow-up. The patients completed a questionnaire preoperatively and 3 months, 5 years, and 10 years postoperatively. Outcome measures were satisfaction with the surgical outcomes, the Oswestry Disability Index (ODI), the visual analog scale (VAS), the numeric rating scale (NRS-11), and walking ability quantified in meters. Postoperative improvements at 5 and 10 years were analyzed using linear mixed models. Furthermore, comparisons between postoperative time points were made for clinical courses of pain, disability, and walking ability. Results At the 10-year follow-up, 68% of the patients were satisfied with the surgical outcomes. All the measured outcomes showed statistically significant improvement from baseline to the 5- and 10-year follow-up. The mean VAS score was 9.8 mm higher at the 5-year follow-up and 7.8 mm at the 10-year follow-up compared to the 3-month follow-up point. Similarly, the mean ODI was 4.8% higher at the 10-year follow-up compared to the 3-month follow-up point. Conclusion This study reports the clinical course of pain, disability, and walking distance after LSS surgery with the 10-year follow-up. Based on our study results, patients with LSS could expect to have positive effects of their back surgery up to 10 years. However, minor worsening in pain and disability may occur and one-fourth of the patients may need a reoperation during the 10-year follow-up period.

Purpose. The objective of this study was to investigate the preliminary effectiveness of percutaneous endoscopic transforaminal lumbar interbody fusion (PE-TLIF) for the treatment of lumbar spinal stenosis (LSS). Methods. From September 2016 to June 2017, a series of seven patients consisting of six females and one male with an average age of 55.25 years (range 43–77 years) who were diagnosed with LSS were involved in this study. All patients were treated by PE-TLIF. During perioperative and follow-up period, demographic data, operation time, intraoperative blood loss, Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), and modified MacNab criteria were evaluated and perioperative complications were documented. Results. All patients were followed up for more than 12 months, with an average follow-up time of 15 (range 12-21) months. The mean VAS of back pain was 7.43 (range 6-8) preoperatively and 0.86 (range 0-2) at the final follow-up. The mean VAS of leg pain was 6.14 (range 4-9) preoperatively and 0.71 (range 0-1) at the final follow-up. The mean ODI was 53.57% (range 38%-63%) preoperatively and 15.57% (range 5%-26%) at the final follow-up. In three-month follow-up, continuous bone trabeculae bridging between intervertebral bodies was seen in 3 cases, and the remaining 4 cases could identify continuous bone trabeculae bridging at 6-month follow-up, reaching the standard of spinal intervertebral fusion. At the final follow-up, 4 patients were rated as excellent (4/7) and 3 patients were rated as good (3/7) according to the modified MacNab criteria. Conclusions. Our study suggested that percutaneous endoscopic transforaminal lumbar interbody fusion could acquire satisfactory treatment effects for the patients with lumbar spinal stenosis, even for the patient who could not afford general anesthesia.

Object. The authors applied the technique of microendoscopic discectomy to posterior decompression procedures for lumbar spinal stenosis. The purpose of this study was to determine the feasibility of using an endoscopic technique to treat lumbar spinal stenosis and to evaluate the clinical and radiographic results of microendoscopic posterior decompression (MEPD). Methods. Microendoscopic posterior decompression, which involves a unilateral endoscopic approach for bilateral decompression, was performed in 47 patients. Clinical and radiographic/neuroimaging results were evaluated during the follow-up period (minimum duration 1 year). The clinical results were compared with those of the conventional laminotomy. Radiographic instability and the degree of surgical invasion of the facet joints were evaluated. In a control a group of 29 patients open laminotomy was performed. The clinical outcome was evaluated in 44 patients. The mean follow-up duration was 22 months. The mean rate of improvement was 72% based on the Japanese Orthopaedic Association score, and good results were obtained in 38 patients. Although the rate of morbidity decreased in the MEPD group, the incidence of complication was slightly higher. Effective decompression was demonstrated in the majority of the patients by using magnetic resonance imaging. Radiographic instability appeared in one patient postoperatively, and based on computerized tomography scanning, a tendency toward invasion of the facet joint on the approach side was noted. Conclusions. Microendoscopic posterior decompression is a minimally invasive procedure and is as useful as other conventional procedures in treating lumbar spinal stenosis; however, a few technical problems remain to be solved.

Background While hylan G-F 20 is an approved therapy for the treatment of knee osteoarthritis, there are few reports of its use in shoulder osteoarthritis. Hypothesis Hylan G-F 20 can reduce pain and improve function in patients with glenohumeral osteoarthritis. Study Design Case series; Level of evidence, 4. Methods Thirty consecutive patients with idiopathic glenohumeral osteoarthritis who failed to respond to standard conservative measures were enrolled. Patients received 3 weekly intra-articular hylan G-F 20 injections in their affected shoulder and completed a visual analog scale for pain, the UCLA score, and the Simple Shoulder Test at baseline and at 1, 3, and 6 months after the third injection. Results Of the 30 patients, 3 withdrew during the washout period before treatment; the remaining patients (17 men and 10 women) had an average age of 62 years. The mean baseline visual analog scale score was 54, UCLA score was 15.7, and Simple Shoulder Test score was 5.7 (of 12 possible “yes” responses). At the 6-month follow-up, hylan G-F 20 significantly improved visual analog scale (mean 30, P < .001), UCLA (mean 24, P < .001), and Simple Shoulder Test (7.6 “yes” responses, P < .001) scores. More patients slept comfortably after treatment (56%) versus before treatment (15%). Nine patients had a visual analog scale improvement >40 points after 6 months. No device-related adverse events were observed. Conclusion Hylan G-F 20 may have a beneficial therapeutic effect on some symptomatic patients with glenohumeral osteoarthritis.

Abstract Background The plantar plate is an important static stabilizer of the lesser metatarsophalangeal joints, and disruptions of the plantar plate can lead to significant instability and lesser toe deformities. In recent years, direct plantar plate repair has been proposed. Although direct repair via a dorsal approach is attractive, a torn plantar plate is small and difficult to access using regular instruments in a restricted operative field. Methods In this report, a unique method for plantar plate repairs was used to repair various configurations of plantar plate tears with standard operative instruments that are available in most operating rooms. Results Using this method, 10 patients underwent plantar plate repairs, and the mean follow-up period was 24 (range, 14–38) months. The mean visual analog scale score for pain preoperatively was 4.1 (range, 0–6) and decreased to 0.6 (range, 0–3) at last follow-up. Postoperatively, the mean visual analog scale score for satisfaction was 9.6 (range, 8–10) and the mean American Orthopedic Foot and Ankle Society forefoot score was 88.8 (range, 75–100). Conclusions Our study proposes an inexpensive and versatile method for plantar plate repair via a dorsal approach that uses standard operative instruments.

Background To evaluate whether decompression in lumbar spinal stenosis without fusion leads to sufficient improvement of back pain and leg pain and whether re-decompression alone is sufficient for recurrent lumbar spinal stenosis for patients without signs of instability. Material and Methods A successive series of 102 patients with lumbar spinal stenosis (with and without previous lumbar surgery) were treated with decompression alone during a 3-year period. Data on pre- and postoperative back pain and leg pain (numerical rating scale [NRS] scale) were retrospectively collected from questionnaires with a return rate of 65% (n = 66). The complete cohort as well as patients with first-time surgery and re-decompression were analyzed separately. Patients were dichotomized to short-term follow-up (< 100 weeks) and long-term follow-up (> 100 weeks) postsurgery. Results Overall, both back pain (NRS 4.59 postoperative versus 7.89 preoperative; p < 0.0001) and leg pain (NRS 4.09 versus 6.75; p < 0.0001) improved postoperatively. The short-term follow-up subgroup (50%, n = 33) showed a significant reduction in back pain (NRS 4.0 versus 6.88; p < 0.0001) and leg pain (NRS 2.49 versus 6.91: p < 0.0001). Similar results could be observed for the long-term follow-up subgroup (50%, n = 33) with significantly less back pain (NRS 3.94 versus 7.0; p < 0.0001) and leg pain (visual analog scale 3.14 versus 5.39; p < 0.002) postoperatively. Patients with previous decompression surgery benefit significantly regarding back pain (NRS 4.82 versus 7.65; p < 0.0024), especially in the long-term follow-up subgroup (NRS 4.75 versus 7.67; p < 0.0148). There was also a clear trend in favor of leg pain in patients with previous surgery; however, it was not significant. Conclusions Decompression of lumbar spinal stenosis without fusion led to a significant and similar reduction of back pain and leg pain in a short-term and a long-term follow-up group. Patients without previous surgery benefited significantly better, whereas patients with previous decompression benefited regarding back pain, especially for long-term follow-up with a clear trend in favor of leg pain.
