RESUMEN
OBJECTIVE: To investigate whether early postoperative walking is associated with "best outcome" and no opioid use at 1 year after lumbar spine surgery and establish a threshold for steps/day to inform clinical practice. DESIGN: Secondary analysis from randomized controlled trial. SETTING: Two academic medical centers in the United States. PARTICIPANTS: We enrolled 248 participants undergoing surgery for a degenerative lumbar spine condition (N=248). A total of 212 participants (mean age, 62.8±11.4y, 53.3% female) had valid walking data at baseline. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Disability (Oswestry Disability Index), back and leg pain (Brief Pain Inventory), and opioid use (yes vs no) were assessed at baseline and 1 year after surgery. "Best outcome" was defined as Oswestry Disability Index ≤20, back pain ≤2, and leg pain ≤2. Steps/day (walking) was assessed with an accelerometer worn for at least 3 days and 10 h/d at 6 weeks after spine surgery, which was considered as study baseline. Separate multivariable logistic regression analyses were conducted to determine the association between steps/day at 6 weeks and "best outcome" and no opioid use at 1-year. Receiver operating characteristic curves identified a steps/day threshold for achieving outcomes. RESULTS: Each additional 1000 steps/d at 6 weeks after spine surgery was associated with 41% higher odds of achieving "best outcome" (95% confidence interval [CI], 1.15-1.74) and 38% higher odds of no opioid use (95% CI, 1.09-1.76) at 1 year. Walking ≥3500 steps/d was associated with 3.75 times the odds (95% CI, 1.56-9.02) of achieving "best outcome" and 2.37 times the odds (95% CI, 1.07-5.24) of not using opioids. CONCLUSIONS: Walking early after surgery may optimize patient-reported outcomes after lumbar spine surgery. A 3500 steps/d threshold may serve as an initial recommendation during early postoperative counseling.

BACKGROUND: The purpose of this study was to investigate the longitudinal postoperative relationship between physical activity, psychosocial factors, and physical function in patients undergoing lumbar spine surgery. METHODS: We enrolled 248 participants undergoing surgery for a degenerative lumbar spine condition. Physical activity was measured using a triaxial accelerometer (Actigraph GT3X) at 6-weeks (6wk), 6-months (6M), 12-months (12M) and 24-months (24M) following spine surgery. Physical function (computerized adaptive test domain version of Patient-Reported Outcomes Measurement Information System) and psychosocial factors (pain self-efficacy, depression and fear of movement) were assessed at preoperative visit and 6wk, 6M, 12M and 24M after surgery. Structural equation modeling (SEM) techniques were utilized to analyze data, and results are represented as standardized regression weights (SRW). Overall SRW were computed across five imputed datasets to account for missing data. The mediation effect of each psychosocial factor on the effect of physical activity on physical function were computed [(SRW for effect of activity on psychosocial factor X SRW for effect of psychosocial factor on function) ÷ SRW for effect of activity on function]. Each SEM model was tested for model fit by assessing established fit indexes. RESULTS: The overall effect of steps per day on physical function (SRW ranged from 0.08 to 0.19, p<0.05) was stronger compared to the overall effect of physical function on steps per day (SRW ranged from non-existent to 0.14, p<0.01 to 0.3). The effect of steps per day on physical function and function on steps per day remained consistent after accounting for psychosocial factors in each of the mediation models. Depression and fear of movement at 6M mediated 3.4% and 5.4% of the effect of steps per day at 6wk on physical function at 12M, respectively. Pain self-efficacy was not a statistically significant mediator. CONCLUSIONS: The findings of this study suggest that the relationship between physical activity and physical function is stronger than the relationship of function to activity. However, future research is needed to examine whether promoting physical activity during the early postoperative period may result in improvement of long-term physical function. Since depression and fear of movement had a very small mediating effect, additional work is needed to investigate other potential mediating factors such as pain catastrophizing, resilience and exercise self-efficacy.

BACKGROUND: The purpose of this prospective case series study was to compare changes in early postoperative physical activity and physical function between 6 weeks and 3 and 6 months after lumbar spine surgery. METHODS: Fifty-three patients (mean [95% confidence interval; CI] age = 59.2 [56.2, 62.3] years, 64% female) who underwent spine surgery for a degenerative lumbar condition were assessed at 6 weeks and 3- and 6-months after surgery. The outcomes were objectively-measured physical activity (accelerometry) and patient-reported and objective physical function. Physical activity was assessed using mean steps/day and time spent in moderate to vigorous physical activity (MVPA) over a week. Physical function measures included Oswestry Disability Index (ODI), 12-item Short Form Health Survey (SF-12), Timed Up and Go (TUG), and 10-Meter Walk (10 MW). We compared changes over time in physical activity and function using generalized estimating equations with robust estimator and first-order autoregressive covariance structure. Proportion of patients who engaged in meaningful physical activity (e.g., walked at least 4400 and 6000 steps/day or engaged in at least 150 min/week in MVPA) and achieved clinically meaningful changes in physical function were compared at 3 and 6 months. RESULTS: After surgery, 72% of patients initiated physical therapy (mean [95%CI] sessions =8.5 [6.6, 10.4]) between 6 weeks and 3 months. Compared to 6 weeks post-surgery, no change in steps/day or time in MVPA/week was observed at 3 or 6 months. From 21 to 23% and 9 to 11% of participants walked at least 4400 and 6000 steps/day at 3 and 6 months, respectively, while none of the participants spent at least 150 min/week in MVPA at these same time points. Significant improvements were observed on ODI, SF-12, TUG and 10 MW (p < 0.05), with over 43 to 68% and 62 to 87% achieving clinically meaningful improvements on these measures at 3 and 6 months, respectively. CONCLUSION: Limited improvement was observed in objectively-measured physical activity from 6 weeks to 6 months after spine surgery, despite moderate to large function gains. Early postoperative physical therapy interventions targeting physical activity may be needed.

BACKGROUND: The United States has the highest rate of lumbar spine surgery in the world, with rates increasing over 200% since 1990. Medicare spends over $1 billion annually on lumbar spine surgery. Despite surgical advances, up to 40% of patients report chronic pain and disability following surgery. Our work has demonstrated that fear of movement is a risk factor for increased pain and disability and decreased physical function in patients following lumbar spine surgery for degenerative conditions. Cognitive-behavioral therapy and self-management treatments have the potential to address psychosocial risk factors and improve outcomes after spine surgery, but are unavailable or insufficiently adapted for postoperative care. Our research team developed a cognitive-behavioral based self-management approach to postoperative rehabilitation (Changing Behavior through Physical Therapy (CBPT)). Pilot testing of the CBPT program demonstrated greater improvement in pain, disability, physical and mental health, and physical performance compared to education. The current study compares which of two treatments provided by telephone - a CBPT Program or an Education Program about postoperative recovery - are more effective for improving patient-centered outcomes in adults following lumbar spine surgery for degenerative conditions. METHODS/DESIGN: A multi-center, comparative effectiveness trial will be conducted. Two hundred and sixty patients undergoing lumbar spine surgery for degenerative conditions will be recruited from two medical centers and community surgical practices. Participants will be randomly assigned to CBPT or Education at 6 weeks following surgery. Treatments consist of six weekly telephone sessions with a trained physical therapist. The primary outcome will be disability and secondary outcomes include pain, general health, and physical activity. Outcomes will be assessed preoperatively and at 6 weeks, 6 months and 12 months after surgery by an assessor masked to group allocation. DISCUSSION: Effective rehabilitation treatments that can guide clinicians in their recommendations, and patients in their actions will have the potential to effect change in current clinical practice. TRIAL REGISTRATION: NCT02184143.

Objective: To describe the safety, feasibility, and preliminary outcomes of an early telephone-supported home exercise program (HEP) performed within the first 6 weeks after anterior cervical discectomy and fusion (ACDF) surgery.Methods: Eight patients (mean ± SD age = 53.4 ± 14.9 years, 5 females) were enrolled in this case series. Immediately after surgery, patients began a 6-week HEP including daily walking, deep breathing, distraction techniques, and cervical and upper body exercises. The HEP was supported by weekly telephone calls by a physical therapist. Safety for performing early exercise was examined with radiographic imaging at 6 months. Adverse events were assessed through weekly calls with a physical therapist. HEP adherence and acceptability data were obtained by patient self-report. Clinical measures were assessed preoperatively, at 6 weeks and at 6 months, and included the Neck Disability Index, Numeric Rating Scale for pain, Tampa Scale of Kinesiophobia, Pain Catastrophizing Scale, Pain Self-Efficacy Questionnaire, and accelerometry for physical activity.Results: Early radiographic imaging showed no signs of nonunion at 6 months. There were no reports of serious adverse events. At 6 months, all patients reported clinically significant changes in pain catastrophizing. Seven (88%) patients had clinically significant changes in disability and arm pain, six (75%) patients for neck pain and pain self-efficacy, and five (53%) patients for fear of movement. Only three (43%) of seven patients showed increased physical activity at 6 months.Conclusion: Based on this small case series, an early telephone-supported HEP appears safe for patients, feasible to implement, and promising for clinical benefits.

BACKGROUND CONTEXT: Positive psychosocial factors early after surgery, such as resilience and self-efficacy, may be important characteristics for informing individualized postoperative care. PURPOSE: To examine the association of early postoperative resilience and self-efficacy on 12-month physical function, pain interference, social participation, disability, pain intensity, and physical activity after lumbar spine surgery. STUDY DESIGN/SETTING: Pooled secondary analysis of prospectively collected trial data from two academic medical centers. PATIENT SAMPLE: Two hundred and forty-eight patients who underwent laminectomy with or without fusion for a degenerative lumbar condition. OUTCOME MEASURES: Physical function, pain inference, and social participation (ability to participate in social roles and activities) were measured using the Patient Reported Outcomes Measurement Information System. The Oswestry Disability Index, Numeric Rating Scale, and accelerometer activity counts were used to measure disability, pain intensity, and physical activity, respectively. METHODS: Participants completed validated outcome questionnaires at 6 weeks (baseline) and 12 months after surgery. Baseline positive psychosocial factors included resilience (Brief Resilience Scale) and self-efficacy (Pain Self-Efficacy Questionnaire). Multivariable linear regression analyses were used to assess the associations between early postoperative psychosocial factors and 12-month outcomes adjusting for age, sex, study site, randomized group, fusion status, fear of movement (Tampa Scale for Kinesiophobia), and outcome score at baseline. This study was funded by Patient-Centered Outcomes Research Institute and Foundation for Physical Therapy Research. There are no conflicts of interest. RESULTS: Resilience at 6 weeks after surgery was associated with 12-month physical function (unstandardized beta=1.85 [95% confidence interval [CI]: 0.29; 3.40]), pain interference (unstandardized beta=-1.80 [95% CI: -3.48; -0.12]), social participation (unstandardized beta=2.69 [95% CI: 0.97; 4.41]), and disability (unstandardized beta=-3.03 [95% CI: -6.04; -0.02]). Self-efficacy was associated with 12-month disability (unstandardized beta=-0.21 [95% CI: -0.37; -0.04]. CONCLUSIONS: Postoperative resilience and pain self-efficacy were associated with improved 12-month patient-reported outcomes after spine surgery. Future work should consider how early postoperative screening for positive psychosocial characteristics can enhance risk stratification and targeted rehabilitation management in patients undergoing spine surgery.

STUDY DESIGN: Pilot randomized controlled trial. OBJECTIVE: To examine the acceptability and preliminary safety and outcome effects of an early self-directed home exercise program (HEP) performed within the first 6 weeks after anterior cervical discectomy and fusion (ACDF). SUMMARY OF BACKGROUND DATA: Little is known regarding optimal postoperative management after ACDF. METHODS: Thirty patients (meanâ±âstandard deviation, ageâ=â50.6â±â11.0 years, 16 women) undergoing ACDF were randomized to receive an early HEP (nâ=â15) or usual care (nâ=â15). The early HEP was a 6-week self-directed program with weekly supportive telephone calls to reduce pain and improve activity. Treatment acceptability was assessed after the intervention period (6 weeks after surgery). Safety (adverse events, radiographic fusion, revision surgery) was determined at routine postoperative visits. Disability (Neck Disability Index), pain intensity (Numeric Rating Scale for neck and arm pain), physical and mental health (SF-12), and opioid use were assessed preoperatively, and at 6 weeks and 6 and 12 months after surgery by an evaluator blinded to group assignment. RESULTS: Participants reported high levels of acceptability and no serious adverse events with the early HEP. No difference in fusion rate was observed between groups (Pâ>â0.05) and no participants underwent revision surgery. The early self-directed HEP group reported lower 6-week neck pain than the usual care group (Fâ=â3.3, Pâ=â0.04, râ=â0.3, mean differenceâ=â-1.7 [-3.4; -0.05]) and lower proportion of individuals (13% vs. 47%) using opioids at 12 months (Pâ=â0.05). No other between-group outcome differences were observed (Pâ>â0.05). CONCLUSION: An early self-directed HEP program was acceptable to patients and has the potential to be safely administered to patients immediately after ACDF. Benefits were noted for short-term neck pain and long-term opioid utilization. However, larger trials are needed to confirm safety with standardized and long-term radiograph assessment and treatment efficacy. LEVEL OF EVIDENCE: 2.

OBJECTIVE: Changing Behavior through Physical Therapy (CBPT), a cognitive-behavioral-based program, has been shown to improve outcomes after lumbar spine surgery in patients with a high psychosocial risk profile; however, little is known about potential mechanisms associated with CBPT treatment effects. The purpose of this study was to explore potential mediators underlying CBPT efficacy after spine surgery. METHODS: In this secondary analysis, 86 participants were enrolled in a randomized trial comparing a postoperative CBPT (n = 43) and education program (n = 43). Participants completed validated questionnaires at 6 weeks (baseline) and 3 and 6 months following surgery for back pain (Brief Pain Inventory), disability (Oswestry Disability Index), physical health (12-Item Short-Form Health Survey), fear of movement (Tampa Scale for Kinesiophobia), pain catastrophizing (Pain Catastrophizing Scale), and pain self-efficacy (Pain Self-Efficacy Questionnaire). Parallel multiple mediation analyses using Statistical Package for the Social Sciences (SPSS) were conducted to examine whether 3- and 6-month changes in fear of movement, pain catastrophizing, and pain self-efficacy mediate treatment outcome effects at 6 months. RESULTS: Six-month changes, but not 3-month changes, in fear of movement and pain self-efficacy mediated postoperative outcomes at 6 months. Specifically, changes in fear of movement mediated the effects of CBPT treatment on disability (indirect effect = -2.0 [95% CI = -4.3 to 0.3]), whereas changes in pain self-efficacy mediated the effects of CBPT treatment on physical health (indirect effect = 3.5 [95% CI = 1.2 to 6.1]). CONCLUSIONS: This study advances evidence on potential mechanisms underlying cognitive-behavioral strategies. Future work with larger samples is needed to establish whether these factors are a definitive causal mechanism. IMPACT: Fear of movement and pain self-efficacy may be important mechanisms to consider when developing and testing psychologically informed physical therapy programs.

STUDY DESIGN: Secondary analysis of randomized controlled trial data. OBJECTIVE: The aim of this study was to examine whether preoperative physical performance is an independent predictor of patient-reported disability and pain at 12 months after lumbar spine surgery. SUMMARY OF BACKGROUND DATA: Patient-reported outcome measures (PROMs) are commonly used to assess clinical improvement after lumbar spine surgery. However, there is evidence in the orthopedic literature to suggest that PROMs should be supplemented with physical performance tests to accurately evaluate long-term outcomes. METHODS: A total of 248 patients undergoing surgery for degenerative lumbar spine conditions were recruited from two institutions. Physical performance tests (5-Chair Stand and Timed Up and Go) and PROMs of disability (Oswestry Disability Index: ODI) and back and leg pain (Brief Pain Inventory) were assessed preoperatively and at 12 months after surgery. RESULTS: Physical performance tests and PROMs significantly improved over 12 months following lumbar spine surgery (Pâ<â0.01). Weak correlations were found between physical performance tests and disability and pain (ρ = 0.15 to 0.32, Pâ<â0.05). Multivariable regression analyses controlling for age, education, preoperative outcome score, fusion, previous spine surgery, depressive symptoms, and randomization group found that preoperative 5-Chair Stand test was significantly associated with disability and back pain at 12-month follow-up. Each additional 10âseconds needed to complete the 5-Chair Stand test were associated with six-point increase in ODI (Pâ=â0.047) and one-point increase in back pain (Pâ=â0.028) scores. The physical performance tests identified an additional 14% to 19% of patients as achieving clinical improvement that were not captured by disability or pain questionnaires. CONCLUSION: Results indicate that physical performance tests may provide distinct information in both predicting and assessing clinical outcomes in patients undergoing lumbar spine surgery. Our findings suggest that the 5-Chair Stand test may be a useful test to include within a comprehensive risk assessment before surgery and as an outcome measure at long-term follow-up.

STUDY DESIGN: A prospective study. OBJECTIVE: The aim of this study was to investigate the impact of various components on patient satisfaction scores SUMMARY OF BACKGROUND DATA.: Patient satisfaction has become an important component of quality assessments. However, with many of these sources collecting satisfaction data reluctant to disclose detailed information, little remains known about the potential determinants of patient satisfaction. METHODS: Two hundred patients were contacted via phone within 3 weeks of new patient encounter with 11 spine providers. Standardized patient satisfaction phone survey consisting of 25 questions (1-10 rating scale) was administered. Questions inquired about scheduling, parking, office staff, teamwork, wait-time, radiology, provider interactions/behavior, treatment, and follow-up communication. Potential associations between these factors and three main outcome measures were investigated: (1) provider satisfaction, (2) overall clinic visit satisfaction, and (3) quality of care. RESULTS: Significant associations (Pâ<â0.0001) with provider satisfaction, overall clinic visit satisfaction, and perceived overall quality of care were found with appointment scheduling, parking, office staff, teamwork, wait time, radiology, provider interactions/behavior, treatment, and follow-up communication. Nurse-practitioner/resident involvement was positively associated with scores (Pâ≤â0.03). A "candy-man" effect was not noted, as pain medication prescribing did not play a significant role in satisfaction (Pâ>â0.05).In multivariate regression analysis, explanation of medical condition/treatment (Pâ=â0.002) and provider empathy (Pâ=â0.04) were significantly associated with provider satisfaction scores, while the amount of time spent with the provider was not. Conversely, teamwork of staff/provider and follow-up communication were significantly associated with both overall clinic visit satisfaction and quality of care (Pâ≤â0.03), while provider behaviors or satisfaction were not. CONCLUSION: Satisfaction with the provider was associated with better explanations of the spine condition/treatment plan and provider empathy, but was not a significant factor in either overall clinic visit satisfaction or perceived quality of care. Patients' perception of teamwork between staff and providers along with reliable follow-up communication were found to be significant determinants of overall patient satisfaction and perceived quality of care. LEVEL OF EVIDENCE: 3.

BACKGROUND: The healthcare reimbursement models are rapidly transitioning to pay-per-performance episode of care payment models. These models, if designed well, must account for the variability in the cost of index surgeries during the global period. OBJECTIVE: To analyze the variability in 90-d cost and determine the drivers of the variability in total 90-d cost associated with single-level microdiscectomy. METHODS: A total of 203 patients undergoing primary microdiscectomy for degenerative lumbar conditions were included in the study. The total 90-d cost was derived as the sum of cost of surgery, cost associated with postdischarge utilization. A multivariable linear regression model for total 90-d cost was built. RESULTS: The mean total cost within 90-d after single-level primary microdiscectomy was $7962 ± $2092. In a multivariable linear regression model, obesity, history of myocardial infarction, factors that lengthen the time of surgery and hospital stay, complications and readmission within 90-d, postdischarge healthcare utilization including emergency room visits, time to opioid independence, number of days on nonopioid pain medications, diagnostic imaging, and the number of days in outpatient and inpatient rehabilitation contribute to the total 90-d cost. The model performance as measured by R2 is 0.76. CONCLUSION: Utilizing prospectively collected data, we highlight major drivers of variation in cost following a single-level primary microdiscectomy. Our model explains about three-quarters of the variation in cost. The risk-adjusted cost estimates powered by models such as the one presented here can be used to formulate a sustainable total 90-d episode of care bundle payment.

The authors describe a previously undocumented complication of suboccipital craniectomy combined with duraplasty for the treatment of Chiari malformation Type I and propose techniques to prevent its occurrence. Although there have been reports of epidural pseudomeningoceles in the setting of spontaneous intracranial hypotension and intracranial hygromas following suboccipital craniectomy with duraplasty, the authors believe this case to be the first instance of quadriparesis caused by the delayed formation of a compressive epidural cerebrospinal fluid collection after suboccipital craniectomy with duraplasty. This complication is significant and must be recognized given the potential severity of neurological insult and the number of these procedures performed yearly in both the pediatric and adult populations.

UNLABELLED: The purpose of this study was to determine the efficacy of a cognitive-behavioral-based physical therapy (CBPT) program for improving outcomes in patients after lumbar spine surgery. A randomized controlled trial was conducted on 86 adults undergoing a laminectomy with or without arthrodesis for a lumbar degenerative condition. Patients were screened preoperatively for high fear of movement using the Tampa Scale for Kinesiophobia. Randomization to either CBPT or an education program occurred at 6 weeks after surgery. Assessments were completed pretreatment, posttreatment and at 3-month follow-up. The primary outcomes were pain and disability measured by the Brief Pain Inventory and Oswestry Disability Index. Secondary outcomes included general health (SF-12) and performance-based tests (5-Chair Stand, Timed Up and Go, 10-Meter Walk). Multivariable linear regression analyses found that CBPT participants had significantly greater decreases in pain and disability and increases in general health and physical performance compared with the education group at the 3-month follow-up. Results suggest a targeted CBPT program may result in significant and clinically meaningful improvement in postoperative outcomes. CBPT has the potential to be an evidence-based program that clinicians can recommend for patients at risk for poor recovery after spine surgery. PERSPECTIVE: This study investigated a targeted cognitive-behavioral-based physical therapy program for patients after lumbar spine surgery. Findings lend support to the hypothesis that incorporating cognitive-behavioral strategies into postoperative physical therapy may address psychosocial risk factors and improve pain, disability, general health, and physical performance outcomes.

BACKGROUND AND PURPOSE: Fear of movement is a risk factor for poor postoperative outcomes in patients following spine surgery. The purposes of this case series were: (1) to describe the effects of a cognitive-behavioral-based physical therapy (CBPT) intervention in patients with high fear of movement following lumbar spine surgery and (2) to assess the feasibility of physical therapists delivering cognitive-behavioral techniques over the telephone. CASE DESCRIPTION: Eight patients who underwent surgery for a lumbar degenerative condition completed the 6-session CBPT intervention. The intervention included empirically supported behavioral self-management, problem solving, and cognitive restructuring and relaxation strategies and was conducted in person and then weekly over the phone. Patient-reported outcomes of pain and disability were assessed at baseline (6 weeks after surgery), postintervention (3 months after surgery), and at follow-up (6 months after surgery). Performance-based outcomes were tested at baseline and postintervention. The outcome measures were the Brief Pain Inventory, Oswestry Disability Index, 5-Chair Stand Test, and 10-Meter Walk Test. OUTCOMES: Seven of the patients demonstrated a clinically significant reduction in pain, and all 8 of the patients had a clinically significant reduction in disability at 6-month follow-up. Improvement on the performance-based tests also was noted postintervention, with 5 patients demonstrating clinically meaningful change on the 10-Meter Walk Test. DISCUSSION: The findings suggest that physical therapists can feasibly implement cognitive-behavioral skills over the telephone and may positively affect outcomes after spine surgery. However, a randomized clinical trial is needed to confirm the results of this case series and the efficacy of the CBPT intervention. Clinical implications include broadening the availability of well-accepted cognitive-behavioral strategies by expanding implementation to physical therapists and through a telephone delivery model.

BACKGROUND CONTEXT: Persistent back pain and leg pain after index surgery is distressing to patients and spinal surgeons. Revision surgical treatment is technically challenging and has been reported to yield unpredictable outcomes. Recently, affective disorders, such as depression and anxiety, have been considered potential predictors of surgical outcomes across many disease states of chronic pain. There remains a paucity of studies assessing the predictive value of baseline depression on outcomes in the setting of revision spine surgery. PURPOSE: To assess the predictive value of preoperative depression on 2-year postoperative outcome after revision lumbar surgery for symptomatic pseudarthrosis, adjacent segment disease (ASD), and same-level recurrent stenosis. STUDY DESIGN: Retrospective cohort study. PATIENT SAMPLE: One hundred fifty patients undergoing revision surgery for symptomatic ASD, pseudarthrosis, and same-level recurrent stenosis. OUTCOME MEASURES: Patient-reported outcome measures were assessed using an outcomes questionnaire that included questions on health-state values (EQ-5D), disability (Oswestry Disability Index [ODI]), pain (visual analog scale), depression (Zung Self-Rating Depression Scale), and 12-Item Short Form Health Survey physical and mental component scores. METHODS: One hundred fifty patients undergoing revision neural decompression and instrumented fusion for ASD (n=50), pseudarthrosis (n=47), or same-level recurrent stenosis (n=53) were included in this study. Preoperative Zung Self-Reported Depression Scale score was assessed for all patients. Preoperative and 2-year postoperative visual analog scale for back pain and leg pain scores and ODI were assessed. The association between preoperative Zung Depression Scale score and 2-year improvement in disability was assessed via multivariate regression analysis. RESULTS: Compared to preoperative status, VAS-BP was significantly improved 2 years after surgery for ASD (8.72±1.85 vs. 3.92±2.84, p=.001), pseudoarthrosis (7.31±0.81 vs. 5.06±2.64, p=.001), and same-level recurrent stenosis (9.28±1.00 vs. 5.00±2.94, p=.001). Two-year ODI was also significantly improved after surgery for ASD (28.72±9.64 vs. 18.48±11.31, p=.001), pseudoarthrosis (29.74±5.35 vs. 25.42±6.00, p=.001), and same-level recurrent stenosis (36.01±6.00 vs. 21.75±12.07, p=.001). Independent of age, BMI, symptom duration, smoking, comorbidities, and level of preoperative pain and disability, increasing preoperative Zung depression score was significantly associated with less 2-year improvement in disability (ODI) after revision surgery for ASD, pseudoarthrosis, and recurrent stenosis. CONCLUSIONS: Our study suggests that the extent of preoperative depression is an independent predictor of functional outcome after revision lumbar surgery for ASD, pseudoarthrosis, and recurrent stenosis. Future comparative effectiveness studies assessing outcomes after revision lumbar surgery should account for depression as a potential confounder. The Zung depression questionnaire may help risk stratify patients presenting for revision lumbar surgery.

BACKGROUND CONTEXT: Laminectomy for lumbar stenosis-associated radiculopathy is associated with improvement in pain, disability, and quality of life. However, given rising health-care costs, attention has been turned to question the cost-effectiveness of lumbar decompressive procedures. The cost-effectiveness of multilevel hemilaminectomy for radiculopathy remains unclear. PURPOSE: To assess the comprehensive medical and societal costs of multilevel hemilaminectomy at our institution and determine its cost-effectiveness in the treatment of degenerative lumbar stenosis. STUDY DESIGN: Prospective single cohort study. PATIENT SAMPLE: Fifty-four consecutive patients undergoing multilevel hemilaminectomy for lumbar stenosis-associated radiculopathy after at least 6 months of failed conservative therapy were included. OUTCOME MEASURES: Self-reported measures were assessed using an outcomes questionnaire that incorporated total back-related medical resource utilization, missed work, and improvement in leg pain (visual analog scale for leg pain [VAS-LP]), disability (Oswestry Disability Index [ODI]), quality of life (Short Form-12 [SF-12]), and health state values (quality-adjusted life years [QALYs], calculated from EuroQuol 5D [EQ-5D] with US valuation). METHODS: Over a 2-year period, total back-related medical resource utilization, missed work, and improvement in leg pain (VAS-LP), disability (ODI), quality of life (SF-12), and health state values (QALYs, calculated from EQ-5D with US valuation) were assessed. 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). Mean total 2-year cost per QALY gained after multilevel hemilaminectomy was assessed. RESULTS: Compared with preoperative health states reported after at least 6 months of medical management, a significant improvement in VAS-LP, ODI, and SF-12 (physical and mental components) was observed 2 years after multilevel hemilaminectomy, with a mean 2-year gain of 0.72 QALYs. Mean±standard deviation total 2-year cost of multilevel hemilaminectomy was $24,264±10,319 (surgery cost, $10,220±80.57; outpatient resource utilization cost, $3,592±3,243; and indirect cost, $10,452±9,364). Multilevel hemilaminectomy was associated with a mean 2-year cost per QALY gained of $33,700. CONCLUSIONS: Multilevel hemilaminectomy improved pain, disability, and quality of life in patients with lumbar stenosis-associated radiculopathy. Total cost per QALY gained for multilevel hemilaminectomy was $33,700 when evaluated 2 years after surgery with Medicare fees, suggesting that multilevel hemilaminectomy is a cost-effective treatment of lumbar radiculopathy.

PURPOSE: To compare transabdominal ultrasonography (US) with fetal magnetic resonance (MR) imaging in the prenatal evaluation of myelomeningocele lesion level. MATERIALS AND METHODS: Prenatal US images, pre- and postnatal MR images, and postnatal spinal radiographs obtained in the first 100 fetuses who underwent intrauterine myelomeningocele repair were the basis for this study. Each image was used to assign a lesion level. The assigned levels were compared by means of the kappa statistic, as an index of agreement. RESULTS: All fetuses underwent prenatal US. Sixty-one fetuses underwent prenatal MR imaging. Fifty fetuses underwent both postnatal spinal radiography and postnatal MR imaging, and an additional 34 fetuses underwent one postnatal study but not the other. When findings on prenatal US images were compared with those on postnatal radiographs, the findings agreed within one spinal level in 79% (55 of 70, kappa = 0.60) of cases. When findings on prenatal MR images were compared with those on postnatal radiographs, the findings agreed in 82% (31 of 38, kappa = 0.63) of cases. Findings on postnatal MR images and those on postnatal spinal radiographs agreed within one spinal level in 100% (50 of 50, kappa = 1.0) of cases. CONCLUSION: Findings at prenatal MR imaging and prenatal US are equally accurate for the assignment of a lesion level in a fetus with myelomeningocele. Given that findings with both modalities will lead to misdiagnosis of the spinal level by two or more segments in at least 20% of cases, care should be exercised when neurologic outcome is predicted on the basis of these studies alone.

BACKGROUND: Animal experiments have suggested that the intrauterine environment causes secondary injury to the congenitally dysplastic spinal cord. This in turn suggests that early closure of the myelomeningocele sac might prevent secondary injury and therefore improve neurologic outcome. This study was designed to examine the technical feasibility of performing intrauterine myelomeningocele repair using a robot-assisted endoscopic system in an animal model. METHODS: Six fetal sheep underwent creation and repair of a full-thickness skin lesion using the da Vinci system. RESULTS: With the device's advanced articulated instruments and three-dimensional optics, it was possible to endoscopically repair the induced skin defects. CONCLUSION: We conclude that, with the recent evolution in robotics and minimally invasive techniques, intrauterine endoscopic surgery has become a realistic goal that promises to reduce the associated risks of fetal surgery and extend the indications for its use.
