Introduction. Functional deficits persist in a significant percentage of total hip arthroplasties (THA), leading to patient dissatisfaction. Spinal stenosis is a leading cause of chronic disability and lower extremity weakness. Although previous studies have evaluated the potential benefit of THA on back pain, none have reported the effects of spine disability on functional outcomes and patient satisfaction with THA. Methods. 244 primary THAs (233 patients) with minimum 2-year follow-up rated their satisfaction, return to activity, and standard hip outcomes using the Oxford Hip Score (OHS). History of lumbar spine pain, lumbar surgery, and daily activity limitations was documented and an Oswestry Disability Index (ODI) score was calculated. Results. 151 of 244 (62%) patients reported a history of back problems: 35 patients (14%) – history of lumbar surgery, 91 (37%) – daily low back pain, and 97 (40%) – back pain that limited activity. Patients with a history of back problems had lower OHS scores than those without, p=0.0001. Pain relief was reported by 93% versus resumption of activities in 82% of THA patients, p=0.025. Increasing spine disability, as determined by ODI, correlated with poor OHS, p<0.0001. Spine disability (ODI) was directly associated with patient dissatisfaction for pain relief (R=0.41, p<0.0001), return to activity (R=0.34, p<0.0001), and overall surgical results (ODI, R=0.38, p<0.0001) at 2 years after THA. Patient age, gender, and BMI were not associated with poor THA outcomes. Conclusions. The majority of THA patients have a history of lumbar spine problems. The Oswestry Spine Disability Index, which is the primary outcome measure of spinal disorders, correlated strongly with poor THA outcomes. Moderate and severe lumbar spine disability directly correlated with worse Oxford Hip Scores. Spine disability was directly associated with THA dissatisfaction

Purpose. The purpose of this study was to investigate the difference in the level of pre- and 6 months post-operative objective and subjective measures of disability between patients with full-thickness rotator cuff tears and those with impingement syndrome/low grade partial thickness rotator cuff tears. Impact of age, gender, and job demands was taken into consideration. Methods. Standardised pre- and post-operative data were collected on consecutive patients who had undergone surgery related to rotator cuff pathology. A disease-specific disability measure, the Western Ontario Rotator Cuff (WORC) Index which explores five domains of physical symptoms – life style, work, sports, and emotions – was the primary outcome. Paired and independent non-parametric statistics and multivariable regression analysis were performed. Results. Three hundred and thirty patients (140 women and 190 men) with a mean age of 58 years (range, 21-82) met the inclusion criteria. Two hundred and fifteen (65%) patients had full-thickness rotator cuff tears and 115 (35%) had impingement or partial thickness rotator cuff tears. Patients with full-thickness tears complained of greater weakness and had a higher prevalence of a fall on an outstretched hand. They were significantly weaker in elevation both pre- (p=0.0002) and post-operatively (< 0.0001). Patients with impingement syndrome expressed more emotional disability both prior to (0.007) and after surgery (0.004). Both groups showed a statistically significant improvement in overall pain, disability and strength 6 months following surgery (p< 0.0001). Factors that affected emotional disability at both time points were job demands and age. Females were more emotionally disabled before surgery. Conclusion. Patients with impingement syndrome and less extensive tears tend to be more emotionally disabled due to their gender, age and work status/job demands. This needs to be considered when planning for return to work and other activities and when assessing treatment outcomes

Purpose. To examine measurement properties of four disability outcomes in patients with advanced osteoarthritis of the glenohumeral joint. Methods. This was a prospective longitudinal study of patients with advanced osteoarthritis of the glenohumeral joint who underwent a Total Shoulder Arthroplasty (TSA) and were followed for 6 months. Four measures [Western Ontario Osteoarthritis Shoulder (WOOS) Index, the American Shoulder and Elbow Surgeons (ASES) assessment, Constant-Murley score (CMS), and Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH)] were completed 2-3 weeks before surgery and at 6 months after surgery. Results. Seventy-seven patients (average age: 66, range 35 to 86, 60% women, 40% men) participated in the study. The Cronbach's Coefficient Alpha of subjective measures was high at 0.91, 0.86, and 0.83 for WOOS, ASES, and QuickDASH respectively. All measures were able to discriminate between men and women's levels of disability at p< 0.05. Correlations between pre-operative scores were moderate (0.59 to -0.79) and slightly increased post-operatively (0.61 to -0.87). All measures were sensitive in detecting change in the disability status over a period of 6 months. Conclusion. All four disability measures were reliable and valid for use in patients with advanced osteoarthritis of the glenohumeral joint. Outcome measurement in busy clinics can be facilitated by choosing valid and reliable measures that have the advantage of simplicity for use by patients and clinicians. The consensus-based standards for selection of outcome measures have been developed for hip and knee arthritis and need to take place for the shoulder joint. Developing consensus by an international group of experts will improve consistency in using outcome measures in patients with shoulder problems

Long term outcomes of distal radius fractures have rarely been studied prospectively and do not traditionally extend past 1–2 years following treatment. The purpose of this study was to describe the long term patient-rated pain and disability of patients after a distal radius fracture and to also determine the differences in patient reported pain and disability after one year following injury and at the long term follow-up. Patients who had previously participated in a prospective study, where baseline and standardised one year follow-up were performed following a distal radius fracture were contact to participate in this long term follow-up (LTFU) study. Eligible cases that consented agreed to evaluation which included being sent a package in the mail contain a letter of information and questionnaire. Baseline demographic data including age and sex, as well as date of fracture, mechanism of fall and attending physician information was obtained for all participating subjects. Patient rated pain and disability was measured at baseline, one year and at long-term follow-up using the Patient Rated Wrist Evaluation (PRWE). Patients were categorised as having had a worse outcome (compared to one year follow-up PRWE scores) if their LTFU PRWE score increased by 5 points, having no change in status (if their score changed by four or less points) or improved if their LTFU PRWE score decreased by 5 or more points. Sixty-five patients (17 male, 48 female) with an average age of 57 years at the time of injury and 67 years at follow-up were included in the study. The mean length of follow-up was 10.7 (± 5.8) years (range: 3–19 years). Overall, 85% of patients reported having no change or had less patient-reported pain and disability (PRWE) at their long-term follow-up compared to their one year PRWE scores. As well, one year PRWE scores were found to be predictive (20.2%) of the variability in long term PRWE score (p=0.001). This study provided data on a cohort of prospectively followed patients with a distal radius fracture, approximately 10 years after injury. This data may be useful to clinicians and therapists who are interested in determining the long term effects of this frequently occurring upper extremity fracture. The results of this study indicate that after 10 years following a distal radius fracture, 85% of patients will have good outcomes. The results of this study also indicate that majority of cases, if patients have a low amount of pain and disability at one year, then these outcomes will also be true approximately 10 years later

Introduction. In all traumatic injury there is a clear relationship between the structural tissue damage and resultant disability after recovery. There are no publications that compare significant thoracolumbar osseous injury to non specific soft tissue injury. Aim. To compare spinal outcome measures between patients with self reported back pain in the workplace perceived as injury to those having sustained structural injury in the form of an unstable thoracolumbar fracture requiring surgical stabilisation. Method. Two consecutive cohorts consisting of 23 patients with healed thoracolumbar fractures and 21 patients with a perception of work related injury were compared. Patient outcomes were measured using the Oswestry Disability Index (ODI), Low Back Outcome score (LBOS), Modified Somatic Perception (MSP) and Modified Zung Depression (MZD) indices. Results. 23 patients (8 females; 15 males) with spinal fractures (group 1), of average age 42 years were followed up for a mean of 41 months post trauma and compared to 21 patients (6 females; 15 males) with self reported back pain pursuing compensation claims, (group 2), of average age 47 years, mean time since perceived injury of 42 months. Both groups were comparable in terms of age and sex. The average ODI in group 1 was 28% (SD 18.5) compared to 52% (SD 17.1) in group 2 (P: 0.0003). Similarly, LBOS was 39.7 Vs 20.3 (P: 0.0003); MSP 4.3 Vs 9.65 (P: 0.03); and MZD 20.2 Vs 35.9 (P: 0.001) in groups 1 and 2 respectively. Conclusion. Despite high energy trauma and significant structural damage to the spine, post-traumatic patients had better spinal outcome scores in all measures (ODI, LBO, MSP, MZD). There is no ‘dose-response’ relationship to functional outcomes. In fact, the disability seems greater in the lower energy injury which is unique in trauma care

The NDI is a simple 10-item questionnaire used to assess patients with neck pain. The original validation was performed on 52 patients with neck pain and the test-retest on 17 whiplash patients with a 2-day interval. The SF36 measures functional ability, wellbeing and the overall health of patients. It is used in health economics to assess the health utility, gain and economic impact of medical interventions. Objectives were to independently validate the NDI in patients with neck pain and to draw comparison between the NDI and SF36. 160 patients with neck pain attending the spinal clinic completed self-assessment questionnaires. A second questionnaire was completed in 34 patients after a period of 1-2 weeks. The internal consistency of the NDI and SF36 was calculated using Cronbach alpha. The test-retest reliability was assessed using the Bland and Altman method and the concurrent validity between the two questionnaires was assessed using Pearson correlation. Both questionnaires showed robust internal consistency: SF36 alpha = 0.878 (se=0.014, 95%CI=0.843 to 0.906) and NDI = 0.864 (se=0.017, 95%CI=0.825 to 0.894). The NDI had significant correlation to all eight domains of the SF36 (p<0.001). The individual scores for each of the ten items had significant correlation with the total disability score (p<0.001). The test-retest reliability of the NDI was acceptable. We have shown irrefutably that the NDI has good reliability and validity and that it stands up well to the SF36

Purpose of the study:. To describe the incidence, nature, and risk factors associated with upper limb injuries in athletes participating in the London 2012 Paralympic Games. Materials and methods:. This study formed a component of the large prospective cohort study conducted over the 14-day period of the London 2012 Paralympic Games, coordinated through the IPC Medical Committee. Daily injury data were collected by team physicians in 3 329 athletes (46 606 athlete days) participating in the study, and 258 upper limb injuries were recorded. The incidence proportion (IP=number of injuries per 100 athletes), and incidence (number of injuries per 1000 athlete days) of upper limb injuries was calculated. Results:. The overall IP (with 95% CI) of upper limb injuries was 7,2 (6,4–8,1), with an incidence of 5,2 (4,6–5,8). Shoulder injuries were encountered most frequently with an overall incidence of 2,2 (1,85–2,7) and caused the greatest amount of time lost from sport. The incidence of shoulder injuries by sport was 8,8 (5,4–13,5) in powerlifting, 5,0 (2,1–9,8) in Judo, 2,8 (1,2–5,6) in wheelchair basketball, and 2,7 (1,6–4,2) in swimming. The incidence of injuries of the wrist and hand was 3,9 (1,4–8,5) in goal ball, 3,2 (1,5–6,0) in wheelchair basketball, and 2,8 (1,3–5,4) in table tennis. The majority of upper limb injuries occurred in athletes with spinal cord injuries (38,3%) and athletes with amputation or limb deficiency (28,4%). Rotator cuff impingement syndrome and chronic rotator cuff injury were the most frequent specific diagnoses in the upper limb injuries. Conclusion:. To date, this is the largest study evaluating upper limb injuries at the Paralympic Games. The shoulder is the anatomical region most frequently injured and caused the greatest time lost from sport. Type of sport, older age group, and athlete disability category were identified as risk factors for upper limb injuries


Background. Foraminal stenosis is often encountered in patients undergoing decompression for spinal stenosis. Given the increased resection of facets and the presence of the more sensitive dorsal root ganglion, it is hypothesized that patients with foraminal stenosis have poorer postoperative outcomes. Methods. Thirty-one patients undergoing decompression without fusion for lumbar spinal stenosis were evaluated. The degree of foraminal stenosis was determined by 2 independent reviewers for absence of fat around the nerve roots. ImageJ digital imaging software was also used to evaluate the foraminal area. Patients with foraminal stenosis were compared with those without using the Oswestry Disability Index (ODI) and a numerical pain scale for back and leg pain at a minimum of 1 year follow-up. Results. Twenty patients in the foraminal stenosis group were compared with 11 without foraminal stenosis. There were no significant differences between the 2 groups regarding age, sex, comorbidities, number of levels operated on, preoperative ODI, back pain or leg pain scores. The foraminal area was significantly smaller in the foraminal stenosis group. Patients without foraminal stenosis reported significant improvements in ODI (mean 26.0), back pain (mean 3.1) and leg pain scores (mean 5.5). Patients with foraminal stenosis reported significant improvements in ODI (mean 18.8) and leg pain (mean 2.5) but not in back pain (mean 0.3). Comparing the 2 groups, the patients with foraminal stenosis had significantly less improvement in back pain (p = 0.02) and leg pain (p = 0.02). Conclusion. The results of this study suggest that presence of foraminal stenosis is a negative predictor for successful outcome following decompression surgery. This may be related to the increased instability that occurs when a foraminotomy is required. Spinal fusion may reduce this effect, and further study is required. NO DISCLOSURES

Introduction:. There is an increasing trend within the US for utilization of total knee replacement for patients who are still of working-age. Numerous causes have been suggested, ranging from greater participation in demanding sporting activities to the epidemic of obesity. A universal concern is that increased arthritis burden will lead to increased disabilty and unsustainable health-care costs both now and in the future with increasing rates of revision surgery in the years ahead. This raises the critical question: Are younger patients receiving knee replacement prematurely? To address this issue, we compared the severity of operative knee pain and functional status in younger versus older TKR patients, drawing upon a national research registry. Methods:. A cohort of 3314 primary TKR patients was identified from the FORCE national research consortium from all surgeries performed between July 1. st. 2011 and March 30. th. 2012. This set of patients was derived from 120 contributing surgeons in 23 US states. Data characterizing each patient undergoing surgery was derived from patients, surgeons and hospitals, and included the SF 36 Physical Component Score (PCS), the Knee injury and Osteoarthritis Outcome Score (KOOS) and the Oswestry Low Back Pain Disability Questionnaire. WOMAC scores were also calculated from the KOOS data and transformed to a 0-to-100 scale with lower scores representing worse impairment. Using descriptive statistics, we compared the demographic and baseline characteristics of patients younger than 65 years of age (n = 1326) vs. those 65 years of age and older (n = 1988). Results:. 40.0% of the study poulation was younger than 65 years of age. These younger patients were less likely to be white (86.4% vs. 92.7%, p < 0.0001), had a greater body mass index (mean BMI 33.0 vs. 30.5, p < 0.0001), and included a larger percentage of smokers (9.4% vs. 2.6%, p < 0.0001). There was a striking prevalence of musculo-skeletal co-morbidities in both groups, with half of the total cohort (50.7%) reporting impairment of at least one joint in addition to the operated knee. Involvement of additional joints was more common in older patients (56.0%) compared to the younger group (42.9%; p = 0.0001). Younger patients reported greater pain (47.3 vs. 53.9, p < 0.0001) and stiffness (38.1 vs. 46.6, p < 0.0001) in the operative knee joint and poorer overall function as measured by the WOMAC and SF36 PCS (WOMAC 50.2 vs. 53.0, p < 0.0001; PCS 32.1 vs. 33.0, p = 0.001). Function levels in both groups reflect significant impairment at time of surgery. Conclusion:. At the time of TKR, younger patients have fewer medical illnesses, but higher rates of obesity and smoking as well as lower mental health scores. In addition, younger patients have the same or greater functional impairment compared to older patients. This supports the view that there should be earlier and more definitive treatment in younger TKR patients to prevent progression of joint disease. Our data suggest that TKR may benefit at an even earlier stage than at present in patients younger than 65 years of age. While it is likely this would improve short term outcomes, the longer term consequences may outweigh the benefits

Hip instability is one of the most common causes for total hip arthroplasty (THA) revision surgery. Studies have indicated that lumbar fusion (LF) surgery is a risk factor for hip dislocation. Instrumented spine fusion surgery decreases pelvic tilt, which might lead to an increase in hip motion to accommodate this postural change. To the best of our knowledge, spine-pelvis-hip kinematics during a dynamic activity in patients that previously had both a THA and LF have not been investigated. Furthermore, patients with a combined THA and LF tend to have greater disability. The purpose was to examine spine-pelvis-hip kinematics during a sit to stand task in patients that have had both THA and LF surgeries and compare it to a group of patients that had a THA with no history of spine surgery. The secondary purpose was to compare pain, physical function, and disability between these patients. This cross-sectional study recruited participants that had a combined THA and LF (n=10; 6 females, mean age 73 y) or had a THA only (n=11; 6 females, mean age 72 y). Spine, pelvis, and hip angles were measured using a TrakSTAR motion capture system sampled at 200 Hz. Sensors were mounted over the lateral thighs, base of the sacrum, and the spinous process of the third lumbar,12th thoracic, and ninth thoracic vertebrae. Participants completed 10 trials of a standardized sit-to-stand-to-sit task. Hip, pelvis, lower lumbar, upper lumbar, and lower thoracic sagittal joint angle range of motion (ROM) were calculated over the entire task. In addition, pain, physical function, and disability were measured with clinical outcomes: Hip Disability Osteoarthritis Outcome Score (pain and physical function), Oswestry Low Back Disability Questionnaire (disability), and Harris Hip Score (pain, physical function, motion). Physical function performance was measured using 6-Minute Walk Test, Stair Climb Test, and 30s Chair Test. Angle ROMs during the sit-to-stand-to-sit task and clinical outcomes were compared between THA+LF and THA groups using independent t-tests and effect sizes (d). The difference in hip ROM was approaching statistical significance (p=0.07). Specifically, the THA+LF group had less hip ROM during the sit-to-stand-to-sit task than the THA only group (mean difference=11.17, 95% confidence interval=-1.13 to 23.47), which represented a large effect size (d=0.83). There were no differences in ROM for pelvis (p=0.54, d=0.28) or spinal (p=0.14 to 0.97; d=0.02 to 0.65) angles between groups. The THA+LF group had worse clinical outcomes for all measures of pain, physical function, and disability (p=0.01 to 0.06), representing large effect sizes (d=0.89 to 2.70). Hip ROM was not greater in the THA+LF group, and thus this is unlikely a risk factor for hip dislocation during this specific sit-to-stand-to-sit task. Other functional tasks that demand greater excursions in the joints should be investigated. Furthermore, the lack of differences in spinal and pelvis ROM were likely due to the task and the THA+LF group had spinal fusions at different levels. Combined THA+LF results in worse clinical outcomes and additional rehabilitation is required for these patients

There is limited literature on the effects of socioeconomic factors on outcomes after total ankle arthroplasty (TAA). In the setting of hip or knee arthroplasty, patients of a lower socioeconomic status demonstrate poorer post-operative satisfaction, longer lengths of stay, and larger functional limitations. It is important to ascertain whether this phenomenon is present in ankle arthritis patients. This is the first study to address the weight of potential socioeconomic factors in affecting various socioeconomic classes, in terms of how they benefit from ankle arthroplasty. This is retrospective cohort study of 447 patients who underwent a TAA. Primary outcomes included pre-operative and final follow-up AAOS pain, AAOS disability, and SF-36 scores. We then used postal codes to determine median household income using Canadian 2015 census data. Incomes were divided into five groups based on equal amounts over the range of incomes. This method has been used to study medical conditions such as COPD and cardiac disease. These income groups were then compared for differences in outcome measures. Statistical analysis was done using unpaired t-test. A total of 447 patients were divided into quintiles by income. From lowest income to highest income, the groups had 54, 207, 86, 64, and 36 patients, respectively. The average time from surgery to final follow up was 85.6 months. Interestingly, we found that patients within the middle household income groups had significantly lower AAOS disability scores compared to the lowest income groups at final follow-up (26.41 vs 35.70, p=0.035). Furthermore, there was a trend towards middle income households and lower post-operative AAOS pain scores compared to the lowest income group (19.57 vs 26.65, p=0.063). There was also a trend toward poorer AAOS disability scores when comparing middle income groups to high income groups post-operatively (26.41 vs 32.27, p=0.058). Pre-operatively, patients within the middle-income group had more pain, compared to the lowest and the highest income groups. No significant differences in SF-36 scores were observed. There were no significant differences seen in middle income groups compared to the highest income group for AAOS pain post-operatively. There were no significant differences found in pre-operative AAOS disability score between income groups. Patients from middle income groups who have undergone TAA demonstrate poorer function and possibly more pain, compared to lower and higher income groups. This suggests that TAA is a viable option for lower socioeconomic groups and should not be a source of discouragement for surgeons. In this circumstance there is no real disparity between the rich and the poor. Further investigation is needed to explore reasons for diminished performance in middle class patients

This study aimed to identify long-term physical and psychosocial health outcomes in children with overwhelming musculoskeletal sepsis. Children admitted to the Paediatric Intensive Care Unit (PICU) from 1st January 2002 to 31st December 2017 with a musculoskeletal focus of infection were identified. A medical notes review was completed to determine survival and morbidity. Present-day clinical assessment of the musculoskeletal and respiratory systems along with questionnaires on health-related quality of life, mental health and sleep were performed. 70 patients were identified over 15 years. Seven children died acutely (five Pasifika and two Māori children) indicating 10% mortality. Recurrence/chronic infection affected 23%. Growth disturbance affected 18%. The hip joint and proximal femur suffered the worst long-term complications. Children under 2 years most at risk of long-term disability. No patients had chronic respiratory illness beyond 90 days. Fifteen children had symptoms of acute neurological impairment, three of whom had permanent acquired brain injury. Twenty-six survivors (41%) were assessed a mean of 8.2 years (SD 4.5, range 2– 18 years) after discharge. Health-related quality of life scores were on par with normative data. All patients who underwent pulmonary function tests had normal results. Six patients and eight parents screened positive for moderate to severe post-traumatic stress disorder. Paediatric multifocal musculoskeletal sepsis can result in complex illness with multi-organ complications for some children. Māori and Pasifika children are most at risk. Children under 2 years and those with proximal femur and/or hip involvement are most likely to have chronic musculoskeletal sequelae and permanent disability. Other outcomes are favourable with no evidence of chronic lung disease or mean reduced quality of life. A period of rehabilitation for children with identified acquired brain injury should be part of discharge planning

Aims. To assess if older symptomatic children with club foot deformity differ in perceived disability and foot function during gait, depending on initial treatment with Ponseti or surgery, compared to a control group. Second aim was to investigate correlations between foot function during gait and perceived disability in this population. Methods. In all, 73 children with idiopathic club foot were included: 31 children treated with the Ponseti method (mean age 8.3 years; 24 male; 20 bilaterally affected, 13 left and 18 right sides analyzed), and 42 treated with primary surgical correction (mean age 11.6 years; 28 male; 23 bilaterally affected, 18 left and 24 right sides analyzed). Foot function data was collected during walking gait and included Oxford Foot Model kinematics (Foot Profile Score and the range of movement and average position of each part of the foot) and plantar pressure (peak pressure in five areas of the foot). Oxford Ankle Foot Questionnaire, Disease Specific Index for club foot, Paediatric Quality of Life Inventory 4.0 were also collected. The gait data were compared between the two club foot groups and compared to control data. The gait data were also correlated with the data extracted from the questionnaires. Results. Our findings suggest that symptomatic children with club foot deformity present with similar degrees of gait deviations and perceived disability regardless of whether they had previously been treated with the Ponseti Method or surgery. The presence of sagittal and coronal plane hindfoot deformity and coronal plane forefoot deformity were associated with higher levels of perceived disability, regardless of their initial treatment. Conclusion. This is the first paper to compare outcomes between Ponseti and surgery in a symptomatic older club foot population seeking further treatment. It is also the first paper to correlate foot function during gait and perceived disability to establish a link between deformity and subjective outcomes.

This study aims to 1) determine reported cannabis use among patients waiting for thoracolumbar surgery and to 2) identify demographics and health differences between cannabis-users and non-cannabis users. This observational cohort study is a retrospective national multicenter review data from the Canadian Spine Outcomes and Research Network registry. Patients were dichotomized as cannabis users and non-cannabis users. Variables of interest: age, sex, BMI, smoking status, education, work status, exercise, modified Oswestry Disability Index (mODI), the Numerical Rating Scales (NRS) for leg and back pain, tingling/numbness scale, SF-12 Quality of Life Questionnaire - Mental Health Component (MCS), use of prescription cannabis, recreational cannabis, and narcotic pain medication. Continuous variables were compared using an independent t-test and categorical variables were compared using chi-square analyses. Cannabis-use was reported by 28.4% of pre-operative patients (N=704), 47% of whom used prescription cannabis. Cannabis-use was reported most often by patients in Alberta (43.55%), British Colombia (38.09%) and New Brunswick (33.73%). Patients who reported using cannabis were significantly younger (mean=52.9 versus mean=61.21,). There was a higher percentage of concurrent narcotic-use (51.54 %) and smoking (21.5%) reported in cannabis-users in comparison to non-cannabis users (41.09%,p=0.001; 9.51%, p=0.001, respectively). There were significant differences in cannabis-use based on pathology (p=0.01). Patients who report using cannabis had significantly worse MCS scores (difference=3.93, p=0.001), and PHQ-8 scores (difference=2.51, p=0.001). There was a significant difference in work status (p=0.002) with cannabis-users reporting higher rates (20%) of being employed, but not working compared to non-cannabis users (11.13%). Non-cannabis users were more likely to be retired (45.92%) compared to cannabis-users (31.31%). There were no significant differences based on cannabis use for sex, education, exercise, NRS-back, NRS-Leg, tingling-leg, mODI, or health state. Thoracolumbar spine surgery patients are utilizing cannabis prior to surgery both through recreational use and prescription. Patients who are using cannabis pre-operatively did not differ in regards to reported pain or disability from non-users, though they did in demographic and mental health variables

This study aims to 1) determine reported cannabis use among patients waiting for thoracolumbar surgery and to 2) identify demographics and health differences between cannabis-users and non-cannabis users. This observational cohort study is a retrospective national multicenter review data from the Canadian Spine Outcomes and Research Network registry. Patients were dichotomized as cannabis users and non-cannabis users. Variables of interest: age, sex, BMI, smoking status, education, work status, exercise, modified Oswestry Disability Index (mODI), the Numerical Rating Scales (NRS) for leg and back pain, tingling/numbness scale, SF-12 Quality of Life Questionnaire - Mental Health Component (MCS), use of prescription cannabis, recreational cannabis, and narcotic pain medication. Continuous variables were compared using an independent t-test and categorical variables were compared using chi-square analyses. Cannabis-use was reported by 28.4% of pre-operative patients (N=704), 47% of whom used prescription cannabis. Cannabis-use was reported most often by patients in Alberta (43.55%), British Colombia (38.09%) and New Brunswick (33.73%). Patients who reported using cannabis were significantly younger (mean=52.9 versus mean=61.21,). There was a higher percentage of concurrent narcotic-use (51.54 %) and smoking (21.5%) reported in cannabis-users in comparison to non-cannabis users (41.09%,p=0.001; 9.51%, p=0.001, respectively). There were significant differences in cannabis-use based on pathology (p=0.01). Patients who report using cannabis had significantly worse MCS scores (difference=3.93, p=0.001), and PHQ-8 scores (difference=2.51, p=0.001). There was a significant difference in work status (p=0.002) with cannabis-users reporting higher rates (20%) of being employed, but not working compared to non-cannabis users (11.13%). Non-cannabis users were more likely to be retired (45.92%) compared to cannabis-users (31.31%). There were no significant differences based on cannabis use for sex, education, exercise, NRS-back, NRS-Leg, tingling-leg, mODI, or health state.

Untreated clubfoot results in serious disability, but mild to moderate residual deformities can still cause functional limitations and pain. Measuring the impact of clubfoot deformities on children's wellbeing is challenging. There is little literature discussing the variability in outcomes and implications of clubfoot based on where geographically the child resides. Although the use of patient reported outcome measures (PROMs) is steadily growing in pediatric orthopaedics, few studies on clubfoot have incorporated them. The most widely used PROM for pediatric foot and ankle pathology is the Oxford Foot and Ankle Questionnaire for Children (OXFAQ-C) that include a physical, school and play, emotional and shoe wear domains. The aim of this study is to evaluate the validity and regional differences in scores of the OXFAQ-C questionnaire to identify functional disability in children with clubfoot in India and Canada. This is a retrospective cohort study of children in Indian and Canadian clubfoot registries aged 5-16 years who completed >1 parent or child OXFAQ-C. The OXFAQ-C was administered once in 01/2020 to all patients in the Indian registry, and prospectively between 06/2019 and 03/2021 at initial visit, 3, 6, 12 months post-intervention, then annually for the Canadian patients. Demographic, clubfoot, and treatment data were compared to OXFAQ-C domain scores. Descriptive statistics and regression analysis were performed. Parent-child concordance was evaluated with Pearson's Coefficient of Correlation (PCC). The cohort had 361 patients (253 from India, 108 from Canada). Non-idiopathic clubfoot occurred in 15% of children in India and 5% in Canada, and bilateral in 53% in India and 50% in Canada. Tenotomy rate was 75% in India and 62% in Canada. Median age at presentation was 3 months in India and 1 month in Canada. Mean Pirani score at presentation and number of Ponseti casts were 4.9 and 6.1 in India and 5.3 and 5.7 in Canada, respectively. Parents reported lower scores in all domains the older the child was at presentation (p Canadians scored significantly lower for all domains (p < 0 .001), with the difference being larger for child-reported scores. The greatest difference was for physical domain. Canadian parents on average scored their child 6.21 points lower than Indian parents, and Canadian children scored a mean of 7.57 lower than Indian children. OXFAQ-C scores differed significantly between Indian and Canadian children despite similar demographic and clubfoot characteristics. Younger age at presentation and tenotomy may improve OXFAQ-C scores in childhood. Parent-child concordance was strong in this population. The OXFAQ-C is an adequate tool to assess functional outcomes of children with clubfeet. Cultural validation of patient reported outcome tools is critical

Pain management in spine surgery can be challenging. Cannabis might be an interesting choice for analgesia while avoiding some side effects of opioids. Recent work has reported on the potential benefits of cannabinoids for multimodal pain control, but very few studies focus on spinal surgery patients. This study aims to examine demographic and health status differences between patients who report the use of (1) cannabis, (2) narcotics, (3) cannabis and narcotics or (4) no cannabis/narcotic use. Retrospective cohort study of thoracolumbar patients enrolled in the CSORN registry after legalization of cannabis in Canada. Variables included: age, sex, modified Oswestry Disability Index (mODI), Numerical Rating Scales (NRS) for leg and back pain, tingling/numbness leg sensation, SF-12 Quality of Life- Mental Health Component (MCS), Patient Health Questionnaire (PHQ-9), and general health state. An ANCOVA with pathology as the covariate and post-hoc analysis was run. The majority of the 704 patients enrolled (mean age: 59; female: 46.9%) were non-users (41.8%). More patients reported narcotic-use than cannabis-use (29.7% vs 12.9%) with 13.4% stating concurrent-use. MCS scores were significantly lower for patients with concurrent-use compared to no-use (mean of 39.95 vs 47.98, p=0.001) or cannabis-use (mean=45.66, p=0.043). The narcotic-use cohort had significantly worse MCS scores (mean=41.37, p=0.001) than no-use. Patients reporting no-use and cannabis-use (mean 41.39 vs 42.94) had significantly lower ODI scores than narcotic-use (mean=54.91, p=0.001) and concurrent-use (mean=50.80, p=0.001). Lower NRS-Leg pain was reported in cannabis-use (mean=5.72) compared to narcotic-use (mean=7.19) and concurrent-use (mean=7.03, p=0.001). No-use (mean=6.31) had significantly lower NRS-Leg pain than narcotic-use (p=0.011), and significantly lower NRS-back pain (mean=6.17) than narcotic-use (mean=7.16, p=0.001) and concurrent-use (mean=7.15, p=0.012). Cannabis-use reported significantly lower tingling/numbness leg scores (mean=4.85) than no-use (mean=6.14, p=0.022), narcotic-use (mean=6.67, p=0.001) and concurrent-use (mean=6.50, p=0.01). PHQ-9 scores were significantly lower for the no-use (mean=6.99) and cannabis-use (mean=8.10) than narcotic-use (mean=10.65) and concurrent-use (mean=11.93) cohorts. Narcotic-use reported a significantly lower rating of their overall health state (mean=50.03) than cannabis-use (mean=60.50, p=0.011) and no-use (mean=61.89, p=0.001). Patients with pre-operative narcotic-use or concurrent use of narcotics and cannabis experienced higher levels of disability, pain and depressive symptoms and worse mental health functioning compared to patients with no cannabis/narcotic use and cannabis only use. To the best of our knowledge, this is the first and largest study to examine the use of cannabis amongst Canadian patients with spinal pathology. This observational study lays the groundwork to better understand the potential benefits of adding cannabinoids to control pain in patients waiting for spine surgery. This will allow to refine recommendations about cannabis use for these patients

Aims. It is well described that patients with bone and joint infections (BJIs) commonly experience significant functional impairment and disability. Published literature is lacking on the impact of BJIs on mental health. Therefore, the aim of this study was to assess health-related quality of life (HRQoL) and the impact on mental health in patients with BJIs. Methods. The AO Trauma Infection Registry is a prospective multinational registry. In total, 229 adult patients with long-bone BJI were enrolled between 1 November 2012 and 31 August 2017 in 18 centres from ten countries. Clinical outcome data, demographic data, and details on infections and treatments were collected. Patient-reported outcomes using the 36-Item Short-Form Health Survey questionnaire (SF-36), Parker Mobility Score, and Katz Index of Independence in Activities of Daily Living were assessed at one, six, and 12 months. The SF-36 mental component subscales were analyzed and correlated with infection characteristics and clinical outcome. Results. The SF-36 physical component summary mean at baseline was 30.9 (95% CI 29.7 to 32.0). At one month, it was unchanged (30.5; 95% CI 29.5 to 31.5; p = 0.447); it had improved statistically significantly at six months (35.5; 95% CI 34.2 to 36.7; p < 0.001) and at 12 months (37.9; 95% CI 36.4 to 39.3; p < 0.001). The SF-36 mental component summary mean at baseline was 42.5 (95% CI 40.8 to 44.2). At one month, it was unchanged (43.1; 95% CI 41.4 to 44.8; p = 0.458); it had improved statistically significantly at six months (47.1; 95% CI 45.4 to 48.7; p < 0.001) and at 12 months (46.7; 95% CI 45.0 to 48.5; p < 0.001). All mental subscales had improved by the end of the study, but mental health status remained compromised in comparison with the average USA population. Conclusion. BJIs considerably impact HRQoL, particularly mental health. Patients suffering from BJIs reported considerable limitations in their daily and social activities due to psychological problems. Impaired mental health may be explained by the chronic nature of BJIs, and therefore the mental wellbeing of these patients should be monitored closely.

Introduction. The purpose of this study is to evaluate the radiological and clinical outcomes in Northern Ireland of free vascularised fibular bone grafting for the treatment of humeral bone loss secondary to osteomyelitis. Upper limb skeletal bone loss due to osteomyelitis is a devastating and challenging complication to manage for both surgeon and patient. Patients can be left with life altering disability and functional impairment. This limb threatening complication raises the question of salvage versus amputation and the associated risk and benefits of each. Free vascularised fibula grafting is a recognised treatment option for large skeletal defects in long bones but is not without significant risk. The benefit of vascularised over non-vascularised fibula grafts include preservation of blood supply lending itself to improved remodeling and osteointegration. Materials & Methods. Sixteen patients in Northern Ireland had free vascularised fibula grafting. Inclusion criteria included grafting to humeral defects secondary to osteomyelitis. Six patients were included in this study. Patients were contacted to complete DASH (Disabilities of the Arm, Shoulder and Hand) questionnaires as our primary outcome measure. Secondary outcome measures included radiological evaluation of osteointegration and associated operative complications. Complications were assessed via review of Electronic Care Record outpatient and in-patient documents
