Nonsurgical spinal decompression system traction combined with electroacupuncture in the treatment of multi-segmental cervical disc herniation: A case report.

RATIONALE: With the spread of computers and mobile phones, cervical spondylosis has become a common occupational disease in clinics, which seriously affects the quality of life of patients. We used a nonsurgical spinal decompression system (SDS) combined with physical therapy electroacupuncture (EA) to treat a case of mixed cervical spondylosis caused by multi-level cervical disc herniation, and we achieved satisfactory results. PATIENT CONCERNS: A 44-year-old Caucasian Asian woman presented with neck pain and numbness on the left side of the limb. MRI showed the patient's C3-C7 segment cervical disc herniation, and the flexion arch of the cervical spine was reversed. DIAGNOSIS: The patient was diagnosed with a mixed cervical spondylosis. INTERVENTIONS: The patient received a month of physical therapy (SDS traction combined with EA). OUTCOMES: Before and after treatment: VAS score of neck pain decreased from 8 to 0; Cervical spine mobility returned to normal; The grip strength of left hand increased from 7.5 kg to 19.2 kg; Cervical curvature index changed from -16.04% to -3.50%; the physiological curvature of the cervical spine was significantly restored. There was no dizziness or neck discomfort at 6 month and 1 year follow-up. LESSONS SUBSETIONS: SDS traction combined with EA is effective for the treatment of cervical disc herniation and can help restore and rebuild the biomechanical balance of the cervical spine.

Does discectomy improve low back pain as well as radiating pain in patients with lumbar herniated intervertebral disc (HIVD)?

ABSTRACT: Most postoperative patients with herniated lumbar disc complained of lower leg radiating pain (LRP), referred buttock pain (RBP), and low back pain (LBP). When discectomy is performed, improvement in LRP is observed due to spinal nerve irritation. However, long-term LBP due to degenerative changes in the disc may occur postoperatively. In addition, limited research has been reported on the short-term (within 1 year) improvement in LBP after discectomy. This study aimed to evaluate the effectiveness of discectomy in reducing LBP within 1 year postoperatively.Among the 183 patients who underwent discectomy performed by a single surgeon from January 2010 to December 2016, 106 who met the inclusion and exclusion criteria were enrolled. In the 106 patients who underwent lumbar discectomy, 3 types of spine-related pain were pre-operatively assessed and 3, 6, and 12 months postoperatively. Functional outcomes were evaluated, and quality of life was assessed 12 months postoperatively by using the Short-Form 36 questionnaire, which was subdivided into mental and physical components.LBP showed both statistical and clinical improvement within the first 3 months postoperatively, but the improvement was not observed until 12 months postoperatively. RBP and LRP showed both statistical and clinical improvement within the first 3 months and further consistently showed statistical improvement. LBP improved clinically only until 3 months postoperatively regardless of the type of herniation.LBP showed improvement within the first 3 months postoperatively and plateaued afterward, and RBP and radiculopathy showed consistent improvement until 12 months postoperatively. This may explain why patients from 12-month follow-up showed improvement in RBP and radiculopathy but not LBP.

The effect of pedometer-supported walking and telemonitoring after disc hernia surgery on pain and disability levels and quality of life.

AIM: The aim of this study was to determine the effect of pedometer-supported walking and telemonitoring after lumbar disc hernia surgery on pain and disability levels and quality of life. METHODS: This was a randomized controlled trial with two randomly selected groups conducted between March 2018 and January 2019. Sixty-seven participants (33 in the intervention group and 34 in the control group) who had undergone lumbar microdiscectomy were allocated to receive and not to receive walking exercise. Pain and disability levels and quality of life of groups were tested with the McGill Pain Questionnaire, the Oswestry Disability Index and the 36-Item Short Form Survey. Measurements were taken 3 weeks after surgery and following completion of the first, second and third months. RESULTS: Compared with the control group, pain level at the first and second months and disability level at the second and third months in the intervention group were significantly lower (p < 0.05), and in the third month, subdimension scores of quality of life (the physical role difficulty, energy and vitality, mental health, social functionality and pain) were higher (p < 0.05). CONCLUSIONS: Walking after herniated disc surgery decreased pain and disability levels and increased the quality of life; nurses can encourage adherence to walking as an effective intervention.

The effect of mindfulness-based therapy on psychiatric symptoms, psychological well-being, and pain beliefs in patients with lumbar disk herniation.

PURPOSE: This study was conducted to determine the impact of mindfulness-based therapy on psychiatric symptoms, psychological well-being, and pain beliefs in patients with lumbar disk hernia. DESIGN AND METHODS: The study was a nonrandomized pretest-posttest controlled quasi-experimental research and carried out in a total of 64 patients. A personal information form, the Depression Anxiety Stress Scale, the Psychological Well-Being Scale, and the Pain Beliefs Scale were used for data collection. FINDINGS: We observed a statistically significant difference between the intervention and control groups in terms of the posttest mean scores of the psychiatric symptoms, psychological well-being, and pain beliefs. PRACTICE IMPLICATIONS: The results revealed that mindfulness-based therapy has a positive impact on pain beliefs and psychological well-being.

Use of hypnosis preoperatively for surgery of the spine: Pilot study.

INTRODUCTION: Hypnosis is a technique requiring no drugs that acts during the three phases of surgery, reducing stress at the pre-surgical phase and the adminstration of anesthetic drugs during the intraoperative phase, as well as leading to improved management of postoperative pain and quality of life management. MATERIAL ET METHOD: We carried out a retrospective study of 46 patients operated on for herniated disc or one or two-level laminectomy without arthrodesis. All patients benefited from a preoperative hypnosis session and completed a questionnaire about their possible concerns. The day after surgery, patients completed a second questionnaire on their postoperative experience following hypnosis. RESULTATS: Our results indicate that this technique had a positive impact on the management of preoperative stress (80% of patients) and on postoperative quality of life (48% of patients). Pain measured by decreased from 4.8/10 preoperatively to 0.9/10 postoperatively. CONCLUSION: Our results are consistent with previous findings in the literature as to the positive contribution of this technique in the management of preoperative stress and patient quality of life. Further studies are however required involving considerably larger cohorts and more extensive surgeries to confirm the effect of this technique on management of anesthesia and pain in spine surgery.

Impact of knowledge, attitude, and practice (KAP)-based rehabilitation education on the KAP of patients with intervertebral disc herniation.

BACKGROUND: This study aims to quantify the effectiveness of knowledge, attitude, and practice (KAP)-based rehabilitation education on the KAP of patients with intervertebral disc herniation (IDH). METHODS: Seventy IDH patients undergoing conservative treatment in our center from February 2018 to December 2018 were randomly divided into the KAP group and control group by using a table of random numbers. The control group was given traditional health education, while the KAP group was offered with KAP-based rehabilitation education. Both groups were followed up for 3 months after their discharge from the hospital. A self-designed questionnaire form was used to evaluate the KAP quantities of patients. RESULTS: Before health education, the scores of knowledge in the control group and the KAP group were (15.12±3.12) and (15.20±3.28), respectively, showing no significant difference (P>0.05). After the health education, the total score of knowledge, the score of disease knowledge, the score of attitude, and the score of practice were (25.42±3.16), (7.66±0.73), (7.80±0.36), and (7.85±0.68), respectively, in the KAP group, which were significantly higher than those in the control group [(20.31±3.43), (6.83±0.92), (6.41±1.05), and (7.10±1.11), P<0.05]. After health education, the awareness rates of the disease, attitude, and behavior were significantly higher in the KAP group than in the control group (P<0.05). CONCLUSIONS: Rehabilitation education based on the KAP theory can effectively enhance the patients' awareness of the disease, increase their rehabilitation consciousness, and promote them to adopt positive rehabilitation behavior, thus achieving the goal of changing the patients' KAP.

Clinical observation on 120 cases of lumbar disc herniation treated with Yaotongning capsule.

This clinical observation aims to observe and analyze the effect of Yaotongning capsule in the treatment of lumbar disc herniation, and provide valuable guidance for clinical practice. A total of 120 patients who confirmed with lumbar disc herniation in our hospital from January 2016 to December 2018 were enrolled as research objects in this study. On the other hand, another 120 patients who were treated for lumbar disc herniation in our hospital during the same period were classified in the control group. General routine treatment mode was adopted for the control group, while Yaotongning capsule was given to the study group on the basis of general routine treatment. The therapeutic effect was observed and compared between the two groups. The overall treatment efficiency, VAS score, serum cytokine levels and quality of life were compared between the two groups. The results showed the study group exhibited significant improvement compared with control group, p<0.05. The application of Yaotongning capsule can achieve markedly good results in treatment of lumbar disc herniation, which is worthy of popularization and application.

Determination of the Prevalence From Clinical Diagnosis of Sacroiliac Joint Dysfunction in Patients With Lumbar Disc Hernia and an Evaluation of the Effect of This Combination on Pain and Quality of Life.

STUDY DESIGN: A prospective cross-sectional study. OBJECTIVE: To evaluate the prevalence of sacroiliac joint dysfunction in patients with lumbar disc hernia and examine the variations in clinical parameters cause by this combination. SUMMARY OF BACKGROUND DATA: Although one of the many agents leading to lumbar pain is sacroiliac dysfunction, little progress has still been made to evaluate mechanical pain from sacroiliac joint dysfunction within the context of differential diagnosis of lumbar pain. METHODS: Two hundred thirty-four patients already diagnosed with lumbar disc hernia were included in the study. During the evaluation, sacroiliac joint dysfunction was investigated using specific tests, pain levels with a Visual Analog Scale, and the presence of neuropathic pain using Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale. Other clinical assessments were performed using the Beck Depression Inventory, Health Assessment Questionnaire, and Tampa Kinesiophobia Scale. RESULTS: 63.2% of patients were female and 36.8% were male. Mean age was 46.72 ±â€Š11.14 years. The level of sacroiliac joint dysfunction was 33.3% in the research population. In terms of sex distribution, the proportion of women was higher in the group with sacroiliac joint dysfunction (P < 0.05). No significant difference was observed in pain intensity assessed using a Visual Pain Scale between the groups (P > 0.05), but the level of neuropathic pain was significantly higher in the group with dysfunction (P < 0.05). In the group with sacroiliac joint dysfunction, the presence of depression was significantly higher (P = 0.009), functional capacity was worse (P < 0.001), and the presence of kinesophobia was higher (P = 0.02). CONCLUSION: Our study results will be useful in attracting the attention of clinicians away from the intervertebral disc to the sacroiliac joint in order to avoid unnecessary and aggressive treatments. LEVEL OF EVIDENCE: 2.

Factors Associated With Return-to-Work Following Cervical Spine Surgery in Non-Worker's Compensation Setting.

STUDY DESIGN: This study retrospectively analyzes prospectively collected data. OBJECTIVE: Here in this study we aim to determine the factors which impact a patient's ability to return to work (RTW) in the setting of cervical spine surgery in patients without worker's compensation status. SUMMARY OF BACKGROUND DATA: Surgical management of degenerative cervical disease has proven cost-effectiveness and shown significant improvement in quality of life. However, the ability to RTW is an important clinical outcome for preoperatively employed patients. METHODS: All adult patients undergoing elective surgery for cervical degenerative disease at our institution are enrolled in a prospective, web-based registry. A multivariable Cox proportional hazards regression model was built for time to RTW. The variables included in the model were age, sex, smoking status, occupation type, number of levels operated on, ASA grade, body mass index, history of diabetes, history of coronary artery disease (CAD), history of chronic obstructive pulmonary disease (COPD), anxiety, depression, myelopathy at presentation, duration of symptoms more than 12 months, diagnosis, type of surgery performed, and preoperative Neck Disability Index, EuroQol Five Dimensions, and Numeric Rating Scale pain scores for neck pain and arm pain scores. RESULTS: Of the total 324 patients with complete 3-month follow-up data 83% (n = 269) returned to work following surgery. The median time to RTW was 35 days (range, 2-90 d). Patients with a labor-intensive occupation, higher ASA grade, history of CAD, and history of COPD were less likely to RTW. The likelihood of RTW was lower in patients with a diagnosis of disc herniation compared with cervical stenosis, patients undergoing cervical corpectomy compared laminectomy and fusion and patient with longer operative time. CONCLUSION: Our study identifies the various factors associated with a lower likelihood of RTW at 3 months after cervical spine surgery in the non-worker's compensation setting. This information provides expectations for the patient and employer when undergoing cervical spine surgery. LEVEL OF EVIDENCE: 3.

Creating value in spine surgery: using patient reported outcomes to compare the short-term impact of different orthopedic surgical procedures.

BACKGROUND CONTEXT: Society increasingly asks Medicine to create "value" for patients. As health-care costs rise, this question will become more important. Debate exists regarding the relative "value" of many surgical procedures, including spinal surgery. Comparison of the relative value that patients experience after different orthopedic procedures is theoretical, but informs the ongoing debate. METHODS: The Patient Reported Outcome Measurement Information System (PROMIS) assessments for Physical Function, Pain Interference, and Depression are routinely collected in our orthopedic clinics. Patients who underwent lumbar discectomy (DSC) or arthroscopic anterior cruciate ligament reconstruction (ACLR) were retrospectively identified. Data relating to PROMIS domains, patient demographics, and other relevant encounter details were extracted. The primary outcomes were (1) preoperative PROMIS domain scores, (2) scores at a minimum of 40 days postoperatively for DSC patients and 133 days postoperatively for ACLR patients, and (3) the change in scores with surgery. Propensity score matching identified age-, sex-, race-, and comorbidity-matched groups from each cohort. Chi-square tests and nonparametric Kruskal-Wallis tests compared the distribution of outcomes and characteristics. Multivariate linear regression models with interactions between the matched cohort and operative phase estimated the change in the outcomes scores between the two cohorts and controlled for the baseline differences between them. RESULTS: Before surgery, the DSC cohort had lower physical function, higher pain interference and higher depression scores as compared with the ACLR cohort. This pattern remained postoperatively, indicating less desirable outcomes for DSC patients. However, after controlling for their baseline scores, DSC patients experienced significantly greater improvements after surgery of 3.84 (95% CI 1.08-6.60; p=.01), -4.87 (95% CI -7.52 to -2.23; p<.001), and -2.95 (95% CI -5.70 to -0.21; p=.04) points in their physical function, pain interference, and depression scores, respectively, as compared with ACLR patients. CONCLUSIONS: Based upon PROMIS assessments at short-term follow-up, DSC patients receive a larger benefit from surgery than ACLR despite the overall less desirable postoperative PROMIS scores in the DSC cohort. This result, while theoretical, informs the debate regarding the comparative value of DSC to patients.

[A retrospective investigation of the efficiency of transforaminal anterior epidural steroid injections in patients with low back pain and the effects of interventional pain therapy on quality of life]. / Bel agrili hastalarda transforaminal anterior epidural steroid enjeksiyonunun etkinliginin ve girisimsel tedavinin yasam kalitesine etkisinin retrospektif arastirilmasi.

OBJECTIVES: The aim of this retrospective study was to evaluate the efficacy of transforaminal anterior epidural steroid and local anesthetic injections (TAESE) and the effects on quality of life in patients with low back pain. METHODS: The study patients (n=191) were divided into 3 groups: disc herniation (DH), failed back surgery (FBS), and spinal stenosis (SS). A visual analog scale (VAS) and verbal pain scale (VPS) were used to assess patient pain. Scores were measured before treatment (VAS 0), in the first month of application (VAS 1), 3 months (VAS 3), and 6 months (VAS 6). Patient quality of life was examined using the 36-Item Short Form Health Survey (SF-36). RESULTS: In all 3 groups, there was a statistically significant reduction in pain compared with the VAS 0 score at 1, 3, and 6 months (p<0.001). The reduction in VAS/VPS was greatest in the DH group, followed by the FBS and SS groups, respectively. All of the parameters of the SF-36 measurement were lower in the SS patients compared with the DH patients. The quality of life score was lowest in the SS patients, though the physical health and social functioning scores were lowest in the FBS group. CONCLUSION: TAESE is effective and can be safely performed in patients who have low back pain due to DH, FBS, or SS. The quality of life result was less successful in SS patients, particularly in the parameter of physical role limitations.

Postoperative functional exercise for patients who underwent percutaneous transforaminal endoscopic discectomy for lumbar disc herniation.

OBJECTIVE: To explore the effects of postoperative functional exercise on patients who underwent percutaneous transforaminal endoscopic discectomy for lumbar disc herniation. PATIENTS AND METHODS: From January to May 2011, patients who had a lumbar disc herniation and then underwent percutaneous transforaminal endoscopic discectomy were divided randomly into two groups: the intervention group (n=46) and the control group (n=46). The intervention group conducted early functional exercises of passive and autonomic activities after their operations, while the control group conducted routine functional exercises after their operations. Short-term and long-term curative effects and quality of life were compared; risk factors that might affect the rehabilitation effects on the patients were analyzed using logistic regression. RESULTS: The lumbar curvature, lumbar lordosis index and sacral inclination angle of the intervention group were better than that those same spinal stability factors in the control group six months after their operations (p<0.05). Scores for residual lumbocrural pain, straight leg raising, muscle strength (skin) sensory, nerve reflex and lumbar function of patients in the intervention group were better than those scores of the control group (p<0.05). The scores for physiological function, emotional function, activity and social function, mental health and quality of life of the intervention group were better than those of the control group (p<0.05). After 1 year of follow-up, the total effective rate for the intervention group was 82.6%, significantly higher than the control group, which had a total effective rate of 71.7% (p<0.05). After 3 years of follow-up, the score for the intervention group was 97.8%, significantly higher than the control group, which had an overall average score of 89.1% (p<0.05). Logistic regression analysis showed that the type of disc herniation, whether patients abided by their doctors' advice during treatment and protected their lumbar vertebra during treatment, and their age were all influential factors on patient rehabilitation. CONCLUSIONS: Early functional exercises of passive and autonomic activities can improve the postoperative quality of life of patients with lumbar disc herniation and provides a basis for inclusion in postoperative treatment of lumbar disc herniation. Importance should be placed on factors, such as postoperative exercise, that can improve the curative effect of rehabilitation.

Decisional Conflict Among Patients Considering Treatment Options for Lumbar Herniated Disc.

BACKGROUND: Lumbar herniated disc is a "preference-sensitive" condition, in which the optimal treatment choice is crucially dependent on an informed patient's goals and values. Little is known about decisional conflict, defined as an individual's level of uncertainty regarding a decision, in patients considering treatment for lumbar herniated discs. Our work aims to identify factors associated with decisional conflict and areas for improved shared decision making. METHODS: We prospectively surveyed patients seeking treatment for a lumbar herniated disc at L4-L5 and/or L5-S1 with a physician at the UCLA Spine Center. Decisional conflict was measured using the validated SURE questionnaire. We performed univariate and multivariate logistic analysis to identify predictors of decisional conflict. RESULTS: Among the 174 participants surveyed, 47% reported experiencing decisional conflict and 44% changed their treatment preference after the visit, with 61% of these opting for more invasive treatment. Participants with decisional conflict were less satisfied with their treatment decision (P < 0.001) and less willing to recommend their physician (P = 0.003) and physician's medical group to others (P = 0.003). Multivariate analysis revealed that participants were more likely to experience decisional conflict if they consulted with a physiatrist compared with a surgeon (odds ratio [OR], 2.6; P = 0.019) and if they did not feel able to discuss the various treatment options with the doctor during the visit (OR, 8.5; P < 0.001). CONCLUSIONS: Many patients with a lumbar herniated disc experience decisional conflict when choosing a treatment option. Our results highlight the need to implement tools and strategies to improve decisional quality, such as decision aids before consultation.

Anxiety and its predictive value for pain and regular analgesic intake after lumbar disc surgery - a prospective observational longitudinal study.

BACKGROUND: Ongoing pain after surgery is a major problem and influences recovery and the quality of life of the patient. Associations between anxiety and their impact on postoperative pain after herniated disc surgery have been reported, but the results are inconsistent. The aim of the present longitudinal study was to evaluate the predictive value of preoperative anxiety for postoperative ongoing pain and prolonged analgesic intake after herniated disc surgery. METHODS: 106 patients with lumbar disc herniation were evaluated in the study. Anxiety was measured with the Generalized Anxiety Disorder 7-Item Scale (GAD-7) before surgery. Pain intensity was assessed on a numeric rating scale (NRS) at baseline, 6-weeks and 6-months after surgery. Regression analysis was performed to identify independent predictors of pain and regular utilization of analgesics up to 6 months after surgery while controlling for confounding variables. RESULTS: 42.5% of the patients were rated as anxiety cases (sum scores GAD-7 > 5), mean scores of anxiety showed mild to moderate symptom severity, and 43% suffered from chronic pain before surgery. Six months after surgery, 55.6% of the patients indicated pain levels of 4/10 (NRS) or higher and about 40% still took pain medication on a regular basis, regardless of their preoperative classification as anxiety-case (37.7% and 41.5%). The preoperative pain level was statistically significant for ongoing postsurgical pain in all four analyses (p < 0.001). With binary logistic regression analyses, preoperative pain intensity, but neither demographic factors nor preoperative anxiety, was identified as predictor for postoperative pain and need for analgesic medication up to 6 months after lumbar disc surgery. CONCLUSION: We found no evidence for the presence of anxiety before disc surgery being a prognostic factor for ongoing pain and regular postoperative intake of analgesics. Only preoperative pain intensity was predictive for increased pain and continued need for analgesic medication up to 6 months after lumbar disc surgery. TRIAL REGISTRATION: Clinicaltrials.gov NCT01488617 . Registered 6 December 2011.

The role of physical status versus mental status in predicting the quality of life of patients with lumbar disk herniation.

PURPOSE: To explore the role of physical status versus mental status in predicting the quality of life (QOL) of patients with lumbar disk herniation (LDH). METHOD: In this correlative study 51 patients with LDH were recruited in their conservative stage of treatment. After profiling their physical status, all participants reported about pain level (according to VAS), pain perception using the Pain Catastrophizing Scale (PCS), and disability level (according to Oswestry Low Back Pain Disability Questionnaire). Their mental status was evaluated using the Spielberger's State-Trait Anxiety Inventory (STAI) and the Beck Depression Inventory (BDI-II). Their QOL was evaluated by the World Health Organization Quality of Life Questionnaire, brief version (WHOQOL-BREF). RESULTS: Physical status/disability level correlated with anxiety and depression. While Physical status predicted physical QOL, mental status, and mainly anxiety and depression were the significant predictors of psychological, social, and environmental QOL. CONCLUSIONS: Mental status may play a significant role in reducing most QOL domains among patients with LDH. The evaluation and intervention process should consider both physical and mental status and their relation to the person's QOL. Since QOL is a major parameter in determining intervention type and success this elaborated perspective may contribute to the intervention planning and outcomes. Implications for rehabilitaion A significant mental distress may accompany the physical disability of patients with LDH. The role of this mental distress in reducing the QOL of patients with LDH may be greater than that of their physical disability. The evaluation and intervention for patients with LDH should refer to both physical and mental status and explore their impacts on quality of life in order to elevate intervention success.

Choosing the right rehabilitation setting after herniated disc surgery: Motives, motivations and expectations from the patients' perspective.

OBJECTIVES: This study aims to investigate (1) motives, motivations and expectations regarding the choice for a specific rehabilitation setting after herniated disc surgery and (2) how rehabilitation-related motivations and expectations are associated with rehabilitation outcome (ability to work, health-related quality of life and satisfaction with rehabilitation) three months after disc surgery. METHODS: The longitudinal cohort study refers to 452 disc surgery patients participating in a subsequent rehabilitation. Baseline interviews took part during acute hospital stay (pre-rehabilitation), follow-up interviews three months later (post-rehabilitation). Binary logistic regression and multiple linear regression analyses were applied. RESULTS: (1) Motives, motivations and expectations: Inpatient rehabilitation (IPR) patients stated "less effort/stress" (40.9%), more "relaxation and recreation" (39.1%) and greater "intensity of care and treatment" (37.0%) regarding their setting preference, whereas outpatient rehabilitation (OPR) patients indicated "family reasons" (45.3%), the wish for "staying in familiar environment" (35.9%) as well as "job-related reasons" (11.7%) as most relevant. IPR patients showed significantly higher motivation/expectation scores regarding regeneration (p < .001), health (p < .05), coping (p < .001), retirement/job (p < .01), psychological burden (p < .05) and physical burden (p < .001) compared to OPR patients. (2) Associations with rehabilitation outcome: Besides other factors (e.g. age, gender and educational level) rehabilitation-related motivations/expectations were significantly associated with rehabilitation outcome measures. For example, patients with less motivations/expectations to achieve improvements regarding "physical burden" showed a better health-related quality of life (p < .01) three months after disc surgery. Less motivations/expectations to achieve improvements regarding "psychological burden" was linked to a better mental health status (p < .001) and a greater satisfaction with rehabilitation (OR = .806; p < .05). CONCLUSION: Rehabilitation-related motivations and expectations differed substantially between IPR and OPR patients before rehabilitation and were significantly associated with rehabilitation outcome. Taking motivational and expectation-related aspects into account may help to improve allocation procedures for different rehabilitation settings and may improve rehabilitation success.

Pre-operative obesity does not predict poorer symptom control and quality of life after lumbar disc surgery.

PURPOSE: We aimed to determine whether there was a difference in post-operative symptomatic control and quality of life (QoL) between patients who were obese (BMI >30) and non-obese (BMI <30) pre-operatively. This information may inform the decision making of Physicians and patients whether to proceed to surgery for management of symptomatic lumbar disc prolapse. METHODS: We conducted a prospective questionnaire-based study of QoL and symptom control in 120 patients with postal follow-up at 3 and 12 months after lumbar disc surgery. This study was conducted in two United Kingdom regional neurosurgical units, with ethical approval from the North of Scotland Research Ethics Service (09/S0801/7). RESULTS: 120 patients were recruited; 37 (34.5%) were obese. Follow up was 71% at 3 months and 57% at 12 months. At recruitment, both obese and non-obese patient groups had similar functional status and pain scores. At 3 and 12 months, non-obese and obese patients reported similar and significant benefits from surgery (e.g. 12 month SF-36 80.5 vs. 68.8, respectively). In non-obese and obese patients, time to return to work was 47.5 days and 53.8 days, respectively, (p = .345). After 12 months all QoL scores were significantly improved from pre-operative levels in both groups. CONCLUSIONS: Obese patients derive significant benefit from lumbar discectomy that it is similar to the benefit experienced by non-obese patients. Obese individuals may achieve excellent results from discectomy and these patients should not be refused surgery on the basis of BMI alone.

The long term outcome of micturition, defecation and sexual function after spinal surgery for cauda equina syndrome.

BACKGROUND: Cauda equina syndrome (CES) is a rare neurologic complication of lumbar herniated disc for which emergency surgical decompression should be undertaken. Despite the common belief that the restoration of functions that are affected by CES can take several years postoperatively, follow up seldom exceeds the first year after surgery. Long term outcome of especially micturition, defecation and sexual function-which are by definition affected in CES-are unknown. The aim of this study is to evaluate 1) postoperative long term outcome of micturition, defecation and sexual function in CES patients 2) attitude of patients towards received hospital care with regard to (recovery of) these functions. METHODS: CES patients were selected by screening the records of all patients operated on lumbar herniated disc in our university hospital between 1995-2010. A questionnaire was sent to the selected CES patients evaluating current complaints of micturition, defecation and sexual function and attitude towards delivered care with focus on micturition, defecation and sexual function. RESULTS: Thirty-seven of 66 eligible CES patients were included (response rate 71%, inclusion rate 56%). Median time after surgery was 13.8 years (range 5.8-21.8 years). Dysfunction at follow up was highly prevalent: 38% micturition dysfunction, 43% defecation dysfunction and 54% sexual dysfunction. Younger age at presentation was associated with sexual dysfunction at follow up: for every year younger at presentation, odds ratio for sexual dysfunction at follow up was 1.11 (p = 0.035). Other associations with outcome were not identified. Two-third of the CES patients wished their neurosurgeon had given them more prognostic information about micturition, defecation and sexual function. CONCLUSION: The presented data demonstrate that dysfunction of micturition, defecation and sexual function are still highly prevalent in a large number of CES patients even years postoperatively. These alarming follow up data probably have a devastating effect on personal perceived quality of life, which should be studied in more detail. CES patients communicate a clear demand for more prognostic information. The presented figures enable clinicians to inform their CES patients more realistically about long term postoperative outcome of micturition, defecation and sexual function after surgical intervention.

Lumbar magnetic resonance imaging findings in patients with and without Waddell Signs.

BACKGROUND CONTEXT: Waddell Signs (WS), introduced as a method to establish patients with substantial psychosocial components to their low back pain, carry a negative association despite no literature evaluating whether physical disease is associated with them. PURPOSE: To compare lumbar magnetic resonance imaging (MRI) findings between the patients with and without WS. STUDY DESIGN: Retrospective cohort study based on prospectively collected data. PATIENT SAMPLE: Thirty patients aged 35 to 55 years with an Oswestry Disability Index (ODI) score >50 randomly selected such that there was an even distribution of patients based on the number of WS. OUTCOME MEASURES: ODI and Short Form-12 scores, number of WS, presence and severity of spinal pathology. METHODS: MRIs were reviewed by three spine specialists blinded to clinical exam findings, number of WS, and patient identity. Type and severity of pathology and presence of surgical and non-surgical lesions were assessed, and findings were rank ordered based on the overall impression of the pathology. There was no external funding or potential conflicts of interest for this study. RESULTS: There were significantly more individual pathologic findings in patients without WS (p=.02). However, there was no difference in the severity of pathology based on WS (p=.46). Furthermore, the rank ordering based on overall impression of severity showed no difference between the patients with and without WS (p=.20). Although 100% of the patients without WS showed pathologic findings on MRI, 70% of WS patients also had significant pathology on MRI. The prevalence of spondylolisthesis, stenosis, and disc herniation was similar (p=.41, p=.22, and p=.43, respectively). The prevalence and mean number of lesion amenable to surgery did not differ based on presence of WS (p=.21 and p=.18, respectively). CONCLUSIONS: Patients with WS present a difficult diagnostic challenge for the physician as their organic symptoms are often coexistent with emotional fear avoidance behavior. Although there is more overall pathology in patients without WS, a significant number of these patients appear to have comparable spinal pathology with equivalent severity, which may be contributing to patients' symptoms and disability. Presence of these non-organic symptoms often makes us doubt these patients. However, as part of effective treatment, physicians should better understand both the physical and psychological components of patient disability.
