Prognosis of Surgical Treatment for Degenerative Lumbar Spinal Stenosis: A Prospective Cohort Study of Clinical Outcomes and Health-Related Quality of Life Across Gender and Age Groups

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

Function after spinal treatment, exercise and rehabilitation (FASTER): improving the functional outcome of spinal surgery

Background: The life-time incidence of low back pain is high and diagnoses of spinal stenosis and disc prolapse are increasing. Consequently, there is a steady rise in surgical interventions for these conditions. Current evidence suggests that while the success of surgery is incomplete, it is superior to conservative interventions. A recent survey indicates that there are large differences in the type and intensity of rehabilitation, if any, provided after spinal surgery as well as in the restrictions and advice given to patients in the post-operative period. This trial will test the hypothesis that functional outcome following two common spinal operations can be improved by a programme of post-operative rehabilitation that combines professional support and advice with graded active exercise and/or an educational booklet based on evidence-based messages and advice.Methods/Design: The study design is a multi-centre, factorial, randomised controlled trial with patients stratified by surgeon and operative procedure. The trial will compare the effectiveness and cost-effectiveness of a rehabilitation programme and an education booklet for the postoperative management of patients undergoing discectomy or lateral nerve root decompression, each compared with "usual care" using a 2 x 2 factorial design. The trial will create 4 sub-groups; rehabilitation-only, booklet-only, rehabilitation-plus-booklet, and usual care only. The trial aims to recruit 344 patients, which equates to 86 patients in each of the four sub-groups. All patients will be assessed for functional ability (through the Oswestry Disability Index - a disease specific functional questionnaire), pain (using visual analogue scales), and satisfaction pre-operatively and then at 6 weeks, 3, 6 and 9 months and 1 year post-operatively. This will be complemented by a formal analysis of cost-effectiveness.Discussion: This trial will determine whether the outcome of spinal surgery can be enhanced by either a postoperative rehabilitation programme or an evidence-based advice booklet or a combination of the two and as such will contribute to our knowledge on how to manage spinal surgery patients in the post-operative period

Are Oblique Views Necessary? A Review of the Clinical Value of Oblique Knee Radiographs in the Acute Setting

Introduction: The purpose of this study was to assess the added clinical value of oblique knee radiographs four-view (4V) compared to orthogonal anteroposterior (AP) and lateral radiographs in a two-view (2V) series. Methods: We obtained 200 adult, 4V knee radiographs in 200 patients in the ED and randomly divided them into two groups with 100 series in each group. Ten reviewers — three musculoskeletal radiologists and seven orthopedic surgeons — performed radiograph analyses. These reviewers were randomly divided evenly into group one and group two. Reviewers were blinded to patient data and first reviewed 2V radiographs (AP/lateral) only, and then reviewed 4V radiographs, including AP/lateral, and two additional oblique views for the same patients at least four weeks later. Acute pathology identification and the need for further imaging was assessed for all reviewers, and clinical decision-making (operative vs nonoperative treatment, need for admission, need for additional imaging) was assessed only by the seven orthopaedic surgeon reviewers.  Results: Mean sensitivity for pathology identification was 79% with 2V and 81% with 4V (P =0.25). Intra-observer kappa value was 0.81 (range 0.54-1.00). Additional oblique radiographs led orthopaedic reviewers to change their treatment recommendations in 62/329 patients (18.84%) (P <0.001). Eight of 329 radiographic series were identified as “critical misses.” (2.43%) (P =0.004), when pathology was reported as normal or reviewers recommended nonoperative treatment on 2V radiographs but changed their recommendation to operative management after the addition of oblique radiographs. The number needed to treat (NNT) for any treatment change and for “critical misses” was 83 and 643, respectively.   Conclusion: Although the addition of oblique radiographs may improve a clinician’s ability to identify subtle pathologic findings not identified on 2V, it rarely leads to significant changes in treatment recommendations. Given the high NNT, limiting the usage of these oblique radiographs in the general patient population may reduce costs without significantly affecting patient care

Trends of Ulnar Collateral Ligament Reconstruction in the United States from 2003 to 2014: Analysis of 3,133 Patients

Purpose: The purpose of this study is to investigate the trends concerning ulnar collateral ligament (UCL) reconstruction (UCLR) for athletic injuries within the United States over the years 2003 to 2014. Methods: A retrospective review of the Truven Health Marketscan® Commercial Database was conducted for patients undergoing UCLR. Data was reviewed for patients treated between 2003 and 2014, and the cohort of patients undergoing UCLR was queried using Common Procedural Terminology code 24346. Patients ages 11 to 40 years were included and divided into 6 different age groups, with the rate of UCLR calculated for each group. RESULTS: The overall rate of UCLR increased from 4.4 per million in 2003 to 11.9 per million in 2014 (p \u3c .01). Throughout the same time period, the rate per million increased from 3.3 to 22.1 in 11- to 15-year-olds (p \u3c .01), from 105.4 to 293.2 in 16- to 20-year-olds (p \u3c .01), from 23.1 to 67.0 in 21- to 25-year-olds (p \u3c .01), and from 2.1 to 5.7 in 31- to 35-year-olds (p \u3c .01). There was no significant increase in the rate of UCLR in the age groups of 26 to 30 and 36 to 40 years. Conclusion: UCLR was mostly performed in patients aged 11 to 25 years (96.6%), and specifically most common in those patients aged 16 to 20 years (67.4%). The rate of UCLR procedures increased over time for younger age groups significantly more than for their older counterparts. Clinical Relevance: UCLR rates are increasing in young patients despite efforts addressing injury risk reduction strategies and education for coaches, players, and parents regarding risk factors for UCL injury

stenosis: a prospective randomized controlled trial

Objective: To assess the effectiveness of therapeutic exercises alone and in combination with a single physical agent - ultrasound - in patients with lumbar spinal stenosis.Design: Randomized, prospective, controlled trial.Setting: Department of Physical Medicine and Rehabilitation, University Hospital.Subjects: Forty-five patients presenting with symptoms of neurological claudication and magnetic resonance image-proven lumbar spinal stenosis were assigned to one of three groups: ultrasound plus exercise group (group 1, n = 15), sham ultrasound plus exercise group (group 2, n = 15) and no exercise - no treatment group (control group, n = 15).Interventions: Stretching and strengthening exercises for lumbar, abdominal, leg muscles as well as low-intensity cycling exercises were given as therapeutic exercises. Ultrasound was applied with 1 mHz, 1.5W/cm(2) intensity, in continuous mode on the back muscle for 10 minutes in group 1 while ultrasound on/off mode was applied in group 2.Main outcome measures: Before and after a three-week period, all subjects were evaluated by pain, disability, functional capacity and consumption of analgesic.Results: Thirty-two of the participants were women and 13 were men, with an average age of 53.2 +/- 12.68 years (range 25-82 years). After a three-week treatment period, leg pain decreased in group 1 (-1.47 +/- 3.02) and group 2 (-2.47 +/- 3.75) compared with the control group (P 0.05). The amount of analgesic consumption is significantly less in the group with ultrasound application compared to that in the control group (P < 0.05).Conclusion: The results of our study suggest that therapeutic exercises are effective for pain and disability in patients with lumbar spinal stenosis and that addition of ultrasound to exercise therapy lowers the analgesic intake substantially
