OBJECTIVEThe authors evaluated the long-term clinical outcome of a total posterior arthroplasty system in the surgical treatment of lumbar spinal stenosis with degenerative spondylolisthesis.METHODSBetween June 2006 and July 2007, 10 patients with neurogenic claudication due to spinal stenosis and single-level degenerative spondylolisthesis were enrolled in a nonrandomized prospective clinical study. The patients were evaluated with radiographs and MRI scans, the visual analog scale (VAS) for back and leg pain, the Oswestry Disability Index (ODI), and the SF-36 health survey preoperatively and at 6 weeks, 3 months, 6 months, 1 year, 2 years, 3 years, 7 years, and 11 years postoperatively.RESULTSThe mean VAS score for leg pain dropped from 83.5 before surgery to 13 at 6 weeks and 17 at 11 years after surgery. The mean VAS score for back pain dropped from 56.2 preoperatively to 12.5 at 6 weeks and 14 at 11 years after surgery. The mean ODI score decreased from 49.1 preoperatively to 13.5 at 6 weeks and 16 at 11 years after surgery. MRI at 11 years demonstrated stenosis adjacent to the stabilized segment in one patient. This patient was not symptomatic. The authors did not find evidence of progression of the spondylolisthesis in any of the cases. In one patient, conversion to posterolateral fusion was performed due to an early device malfunction.CONCLUSIONSThe results of this 11-year follow-up study demonstrate that, in patients with spinal stenosis and degenerative spondylolisthesis, decompression and posterior arthroplasty maintain clinical improvement and radiological stability.

OBJECTIVEThe predominant symptom of lumbar spinal stenosis (LSS) is neurogenic claudication or radicular pain. Some surgeons believe that the presence of substantial back pain is an indication for fusion, and that decompression alone may lead to worsening of back pain from destabilization associated with facet resection. The purpose of this study was to determine if patients with LSS and clinically significant back pain could obtain substantial improvements in back pain after a decompression alone without fusion.METHODSThe DaneSpine database was used to identify 2737 patients with LSS without segmental instability and a baseline back pain visual analog scale (VAS) score ≥ 50 who underwent a decompression procedure alone without fusion. Standard demographic and surgical variables and patient outcomes, including back and leg pain VAS score (0–100), Oswestry Disability Index (ODI), and EQ-5D at baseline and at 12 months postoperatively, were collected.RESULTSA total of 1891 patients (69%) had 12-month follow-up data available for analysis; the mean age was 66.4 years, 860 (46%) were male, the mean BMI was 27.8 kg/m2, and 508 (27%) were current smokers. At 12 months postoperatively, there were statistically significant improvements (p < 0.001) from baseline for back pain (72.1 to 42.1), leg pain (71.2 to 41.3), EQ-5D (0.35 to 0.61), and ODI (44.1 to 27.8).CONCLUSIONSPatients with LSS, clinically substantial back pain, and no structural instability obtain improvement in back pain after decompression-only surgery and do not need a concomitant fusion.

Introduction: Spinal stenosis mostly occur in lumbar spine and causes back pain, leg pain & neurogenic claudication. Although conservative treatment is mainstay, decompression with or without fusion (with or without instrumentation) can be considered in non-responsive cases. However, long term outcome of the surgery is controversial. The aim of our study was to analyze the outcome of surgery in lumbar spinal stenosis in terms of post-operative pain and claudication distance.Methods: A prospective analysis of patients who underwent decompression or decompression with fusion (with or without instrumentation), after failure of 3-6 months conservative treatment, for lumbar spinal stenosis were conducted. Only those who were operated and followed up for at least two years were included.Their preop and postop VAS score and walking distance compared.Results: Of 22 cases enrolled in this study, VAS score was improved in 21 patients and walking distance increased. Only one patient complained of increase in pain score at 24 months.Conclusion: Operative management is a good option for selected patients, 21 out of 22 have improved VAS and claudication distance in our study

Abstract We present a series of 25 elderly patients who exhibited signs and symptoms of neurogenic claudication and who were found to have one or two levels of spinal stenosis. At the time of decompressive surgery, excessive movement was found at the stenotic levels, so a simple stabilization procedure was performed using Knodt rods and a facet fusion. The expectation was that spine fixation would decrease the amount of postoperative back pain, which can be a result of continued abnormal mobility. All of the patients have been followed for 2 or more years. This elderly group of individuals tolerated surgery well, and long-term results were good.

Purpose. The objective of this retrospective study was to evaluate the long-term follow-up results of neurectomy clinical outcomes and complications in the treatment of Morton’s neuroma. Materials and methods. A total of 19 patients (19 different feet) were treated for Morton’s neuroma by excision of the interdigital nerve at our institute between May 1997 and May 1999. Thirteen (13 feet) of them were followed up. The 13 patients were female and had an average age of 43 years (range 34-54 years) at the time of the operation. The patients were followed-up for a mean of 10.5 years (range 10.0-12.2 years) and scored using the American Orthopaedic Foot & Ankle Society (AOFAS) forefoot scoring system and Visual Analogue Scale (VAS) score. Subjective satisfaction was evaluated at the final follow-up. Results. Eight patients scored more than 90 on the AOFAS forefoot scoring system. The VAS score was improved in all patients. The mean preoperative VAS score was 8.6 ± 0.8 cm (7-10) and the mean follow-up VAS score was 2.4 ± 1.8cm (0-6), which indicated no significant difference (P > .05). The final follow-up satisfaction results indicated that 4 patients were completely satisfied with the operation, 4 were satisfied with minor reservations, 5 were satisfied with major reservations, and no patient was unsatisfied. Neurectomy to treat Morton’s neuroma had a good satisfaction rate (61%). Eleven of the patients complained of numbness on the plantar aspect of the foot adjacent to the interspace, and 2 of these 11 patients complained of disability induced by severe numbness. There was a complaint of residual pain by 1 patient. There were no skin problems on the operation lesions. Conclusion. The long-term results of neurectomy clinical outcomes in Morton’s neuroma are slightly worse than the short- and mid-term results.

Abstract Background Although the Nirschl technique was introduced approximately 40 years ago, only limited information is available about the long-term results, especially concerning extensor power changes after surgery. The purpose of this study was to investigate long-term clinical results of surgical treatment of lateral epicondylitis using the modified Nirschl technique. The main outcome variable was muscle strength for wrist extension because the extensor origin was not reattached after removal of the degenerative extensor tendon. Methods Data from 99 patients who underwent surgical lateral epicondylitis treatment between 2007 to 2012 were included in the study. The mean follow-up period was 8.5 years (5 to 10, ± 1.1 years) and the mean age at surgery was 44.8 years (32 to 70, ± 9.8 years). The surgeries were performed using the modified Nirschl method and did not include extensor origin reattachment. Outcome measurements included the Visual Analogue Scale (VAS) score, Disabilities of the Arm, Shoulder and Hand (DASH) score, the MAYO elbow performance score, and Nirschl and Pettrone’s grades. Wrist extension and grip strength were analyzed using a digital handgrip dynamometer (microFET2TM system) and JAMA hand dynamometer. Results Mean time required to return to work was 2.4 months after surgery. At the last follow-up after surgery, the mean VAS score had significantly improved, from 4.9 to 1.1. Mean MAYO elbow performance scores significantly improved, from 64 to 90, and mean DASH scores improved from 50 to 13. The Nirschl and Pettrone’s grades were 80% rated as ‘excellent’ and 16% rated as ‘good’. After adjusting for power differences between the dominant and non-dominant arms, the difference between wrist extensor power of the operated elbow and the non-operated opposite elbow at the final follow-up was not statistically significant. No patients complained about wrist extension weakness. Conclusion Although reattachment of the extensor origin was not performed during the modified Nirschl surgical technique, there was no significant weakness in wrist extension power and the long-term follow-up revealed favorable clinical results. Level of evidence Level IV (case series). Retrospective study.

Object Transforaminal lumbar interbody fusion (TLIF) for spondylolisthesis-associated back and leg pain is associated with improvement in pain, disability, and quality of life. However, given the rising health care costs associated with spinal fusion procedures and varying results of recent cost-utility studies, the cost-effectiveness of TLIF remains unclear. The authors set out to assess the comprehensive costs of TLIF at their institution and to determine its cost-effectiveness in the treatment of degenerative spondylolisthesis. Methods Forty-five patients undergoing TLIF for Grade I degenerative spondylolisthesis–associated back and leg pain after 6–12 months of conservative therapy were included. The authors assessed the 2-year back pain visual analog scale (VAS) score, leg pain VAS score, Oswestry Disability Index, and total back-related medical resource utilization, missed work, and health-state values (quality-adjusted life years [QALYs], calculated from EQ-5D with US valuation). Two-year resource use was multiplied by unit costs based on Medicare national allowable payment amounts (direct cost), and patient and caregiver workday losses were multiplied by the self-reported gross-of-tax wage rate (indirect cost). The mean total 2-year cost per QALY gained after TLIF was assessed. Results Compared with preoperative health states reported after at least 6 months of medical management, a significant improvement in back pain VAS score, leg pain VAS score, and Oswestry Disability Index was observed 2 years after TLIF, with a mean 2-year gain of 0.86 QALYs. The mean ± SD total 2-year cost of TLIF was $36,836 ± $11,800 (surgery cost, $21,311 ± $2800; outpatient resource utilization cost, $3940 ± $2720; indirect cost, $11,584 ± $11,363). Transforaminal lumbar interbody fusion was associated with a mean 2-year cost per QALY gained of $42,854. Conclusions Transforaminal lumbar interbody fusion improved pain, disability, and quality of life in patients with degenerative spondylolisthesis–associated back and leg pain. The total cost per QALY gained for TLIF was $42,854 when evaluated 2 years after surgery with Medicare fees, suggesting that TLIF is a cost-effective treatment of lumbar spondylolisthesis.

Object Advocates of minimally invasive discectomy (MID) have promoted this operation as an alternative to open discectomy (OD), arguing that there may be less injury to the paraspinal muscles, decreased postoperative pain, and a faster recovery time. However, a recently published large randomized controlled trial (RCT) comparing these approaches reported inferior relief of leg pain in patients undergoing MID. The authors conducted a meta-analysis to evaluate complications and improvement in leg pain in patients with radiculopathy enrolled in RCTs comparing OD to MID. Methods The authors performed a literature search using Medline and EMBASE of studies indexed between January 1990 and January 2011. Predetermined RCT eligibility included the usage of tubular retractors during MID, a minimum follow-up duration of 1 year, and quantification of pain with the visual analog scale (VAS). Trials that only evaluated patients with recurrent disc herniation were excluded. Data on operative parameters, complications, and VAS scores of leg pain were extracted by 2 investigators. A meta-analysis was performed assuming random effects to determine the difference in mean change for continuous outcomes and the risk ratio for binary outcomes. Results Six trials comprising 837 patients (of whom 388 were randomized to MID and 449 were randomized to OD) were included. The mean operative time was 49 minutes during MID and 44 minutes during OD; this difference was not statistically significant. Incidental durotomies occurred significantly more frequently during MID (5.67% compared with 2.90% for OD; RR 2.05, 95% CI 1.05–3.98). Intraoperative complications (incidental durotomies and nerve root injuries) were also significantly more common in patients undergoing MID (RR 2.01, 95% CI 1.07–3.77). The mean preoperative VAS score for leg pain was 6.9 in patients randomized to MID and 7.2 in those randomized to OD. With long-term follow-up (1–2 years postoperatively), the mean VAS score improved to 1.6 in both the MID and OD cohorts. There was no significant difference in relief of leg pain between the 2 approaches with either short-term follow-up (2–3 months postoperatively, 0.81 points on the VAS, 95% CI −4.71 to 6.32) or long-term follow-up (2.64 on the VAS, 95% CI −2.15 to 7.43). Reoperation for recurrent herniation was more common in patients randomized to the MID group (8.50% compared with 5.35% in patients randomized to the OD group), but this difference was not statistically significant (RR 1.56, 95% CI 0.92–2.66). Total complications did not differ significantly between the operations (RR 1.50, 95% CI 0.97–2.33). Conclusions The current evidence suggests that both OD and MID lead to a substantial and equivalent long-term improvement in leg pain. Adequate decompression, regardless of the operative approach used, may be the primary determinant of pain relief—the major complaint of many patients with radiculopathy. Incidental durotomies occurred significantly more frequently during MID, but total complications did not differ between the techniques.

OBJECTIVECentral poststroke neuropathic pain is a debilitating syndrome that is often resistant to medical therapies. Surgical measures include motor cortex stimulation and deep brain stimulation (DBS), which have been used to relieve pain. The aim of this study was to retrospectively assess the safety and long-term efficacy of DBS of the posterior limb of the internal capsule for relieving central poststroke neuropathic pain and associated spasticity affecting the lower limb.METHODSClinical and surgical data were retrospectively collected and analyzed in all patients who had undergone DBS of the posterior limb of the internal capsule to address central poststroke neuropathic pain refractory to conservative measures. In addition, long-term pain intensity and level of satisfaction gained from stimulation were assessed. Pain was evaluated using the visual analog scale (VAS). Information on gait improvement was obtained from medical records, neurological examination, and interview.RESULTSFour patients have undergone the procedure since 2001. No mortality or morbidity related to the surgery was recorded. In three patients, stimulation of the posterior limb of the internal capsule resulted in long-term pain relief; in a fourth patient, the procedure failed to produce any long-lasting positive effect. Two patients obtained a reduction in spasticity and improved motor capability. Before surgery, the mean VAS score was 9 (range 8–10). In the immediate postoperative period and within 1 week after the DBS system had been turned on, the mean VAS score was significantly lower at a mean of 3 (range 0–6). After a mean follow-up of 5.88 years, the mean VAS score was still reduced at 5.5 (range 3–8). The mean percentage of long-term pain reduction was 38.13%.CONCLUSIONSThis series suggests that stimulation of the posterior limb of the internal capsule is safe and effective in treating patients with chronic neuropathic pain affecting the lower limb. The procedure may be a more targeted treatment method than motor cortex stimulation or other neuromodulation techniques in the subset of patients whose pain and spasticity are referred to the lower limbs.

Purpose: a comparative analysis of long-term clinical and radiological outcomes of bilateral microsurgical decompression from unilateral approach and open fusion surgery in the treatment of patients with stable stage I lumbar degenerative spondylolisthesis complicated by spinal stenosis. Materials and methods: this study included 83 patients with degenerative stage I lumbar spondylolisthesis, combined with spinal stenosis at one/several levels. Bilateral microsurgical decompression from unilateral approach was performed in group A (n = 41), in group B (n = 42) we used transforaminal lumbar interbody fusion. Results: intraoperative blood loss and operation time significantly prevailed in group B (P < 0,05). Pain in the legs (VAS), Oswestry disability index significantly decreased in both groups in the long-term postoperative period. No statistical difference in these was found in groups A and B (P = 0,59; P = 0,10). Lower back pain in both groups at the follow-up period had a significant difference: in fusion group there was a significantly higher intensity, than in group А (P < 0,001). Assessment of radiological outcomes in group A at the level of spondylolisthesis showed a slight decrease in segment stability: an increase in anteroposterior displacement of the vertebrae by an average of 0,44 mm, the angular difference by 0,77°, an increase in displacement of the vertebral body by 1,30 % (P < 0,05). Conclusion: minimally bilateral microsurgical decompression from unilateral approach is an effective method for treatment of stable stage I degenerative lumbar spondylolisthesis, combined with spinal stenosis, allowing to achieve significant regression of leg pain and disability in the long-term postoperative period. And this method admits to significantly decrease of low back pain, then in fusion surgery, as well as a low risk of postoperative instability and reoperation with instrumentation.

Purpose: To evaluate a new self-expanding nitinol coil stent in stenotic or occluded peripheral arteries. Methods: Seventy-three symptomatic patients (58 men; mean age 67 years) were treated with nitinol stents for lesions in the iliac artery (9 stenoses); superficial femoral artery (SFA) (39 stenoses, 6 occlusions); popliteal artery and tibioperoneal trunk (9 stenoses, 7 occlusions); and 3 bypass grafts. Mean diameter stenosis was 84.4% ± 9.9% (range 75% to 100%), and mean lesion length was 45 ± 23 mm (range 20 to 120 mm). Results: Eighty-eight 40-mm-long stents with diameters between 5 and 8 mm were implanted percutaneously for suboptimal dilation (n = 45); dissection (n = 21); and restenosis (n = 7). All stents but one were implanted successfully; the malpositioned stent was removed, and another stent was successfully deployed. There were 3 (4.1%) failures due to thrombosis at 24 hours. During the mean 16-month follow-up (range to 44 months), 4 restenoses (3 femoral, 1 popliteal) have occurred; 2 were treated with repeat dilation and 2 underwent bypass. Primary and secondary patency rates at 18 months were 87% and 90%, respectively, for all lesions (iliac: 100% for both; femoral: 85% and 88%; popliteal: 87% and 100%). Conclusions: This new nitinol stent seems to be safe and effective with favorable long-term results, even in distal SFA lesions and popliteal arteries. Its flexibility and resistance to external compression allow its placement in tortuous arteries and near joints.
