Aims. To evaluate the impact of negative pressure wound therapy (NPWT) on the odds of having deep infections and health-related quality of life (HRQoL) following open fractures. Methods. Patients from the Fluid Lavage in Open Fracture Wounds (FLOW) trial with Gustilo-Anderson grade II or III open fractures within the lower limb were included in this secondary analysis. Using mixed effects logistic regression, we assessed the impact of NPWT on deep wound infection requiring surgical intervention within 12 months post-injury. Using multilevel model analyses, we evaluated the impact of NPWT on the Physical Component Summary (PCS) of the 12-Item Short-Form Health Survey (SF-12) at 12 months post-injury. Results. After applying inverse probability treatment weighting to adjust for the influence of injury characteristics on type of dressing used, 1,322 participants were assessed. The odds of developing a deep infection requiring operative management within 12 months of initial surgery was 4.52-times higher in patients who received NPWT compared to those who received a standard wound dressing (95% confidence interval (CI) 1.84 to 11.12; p = 0.001). Overall, 1,040 participants were included in our HRQoL analysis, and those treated with NPWT had statistically significantly lower mean SF-12 PCS post-fracture (p < 0.001). These differences did not reach the minimally important difference for the SF-12 PCS. Conclusion. Our analysis found that patients treated with NPWT had higher odds of developing a deep infection requiring operative management within 12 months post-fracture. Due to possible residual confounding with the worst cases being treated with NPWT, we are unable to determine if NPWT has a negative effect or is simply a marker of worse injuries or poor access to early soft-tissue coverage. Regardless, our results suggest that the use of this treatment requires further evaluation. Cite this article: Bone Jt Open 2022;3(3):189–195

Aims. Using data from the Hip Fracture Evaluation with Alternatives of Total Hip Arthroplasty versus Hemiarthroplasty (HEALTH) trial, we sought to determine if a difference in functional outcomes exists between monopolar and bipolar hemiarthroplasty (HA). Methods. This study is a secondary analysis of patients aged 50 years or older with a displaced femoral neck fracture who were enrolled in the HEALTH trial and underwent monopolar and bipolar HA. Scores from the Western Ontario and McMaster University Arthritis Index (WOMAC) and 12-Item Short Form Health Survey (SF-12) Physical Component Summary (PCS) and (MCS) were compared between the two HA groups using a propensity score-weighted analysis. Results. Of 746 HAs performed in the HEALTH trial, 404 were bipolar prostheses and 342 were unipolar. After propensity score weighting, adequate balance between the bipolar and unipolar groups was obtained as shown by standardized mean differences less than 0.1 for each covariable. A total of 24 months after HA, the total WOMAC score and its subcomponents showed no statistically significant difference between the unipolar and bipolar groups. Similarly, no statistically significant difference was found in the PCS and MCS scores of the SF-12 questionnaire. In participants aged 70 years and younger, no difference was found in any of the functional outcomes. Conclusion. From the results of this study, the use of bipolar HA over unipolar design does not provide superior functional outcomes at 24 months postoperatively. The theoretical advantage of reduced acetabular wear with bipolar designs does not appear to influence functional outcomes in the first two years postoperatively.

Elective orthopaedic procedures, and particularly total hip arthroplasty (THA), in octogenarians and nonagenarians patients are burdened of several implications. Besides the comorbidities and the anesthesiological issues, legal and ethical implications are present. Some literature data show the clinical improvement of THA in elderly patient but the psychological aspects are not yet evaluated. Aim of this study is to evaluate the clinical aspects and the psychological impact in daily living in octogenarians and nonagenarians patients addressing THA. We conducted a retrospective evaluation of 81 THA in 81 patients of age more than 85 years with a minimum follow-up of 6 months. Clinical aspects were evaluated using the Hip disability and Osteoarthritis Outcome Score (HOOS). The psychological issues were evaluated with the Short Form 12 (SF-12) using both the Physical Component Summary (PCS) and the Mental Component Summary (MCS). From the starter cohort of 81 patients, 8 patients were died for causes unrelated to surgery, 13 were lost to follow-up, 1 patient was revised for periprosthetic fracture; 59 patients composed the final cohort. Mean HOOS rased from 18,07 ± 17,81 to 92,36 ± 5,74 with statistically significant distribution both in the global score than in all of the different subscales. The PCS raised from 26,81 ± 10,81 to 51,86 ± 4,45 and The MCS raised from 34,84 ± 10,81 to 56,70 ± 5,04, but none of them showed a statistically significant distribution. THA in octogenarians and nonagenarians patients could be a safe procedure with positive results for clinical and psychological aspects

There has been a substantial increase in the surgical treatment of unstable chest wall injuries recently. While a variety of fixation methods exist, most surgeons have used plate and screw fixation. Rib-specific locking plate systems are available, however evidence supporting their use over less-expensive, conventional plate systems (such as pelvic reconstruction plates) is lacking. We sought to address this by comparing outcomes between locking plates and non-locking plates in a cohort of patients from a prior randomized trial who received surgical stabilization of their unstable chest wall injury. We used data from the surgical group of a previous multi-centred, prospective, randomized controlled trial comparing surgical fixation of acute, unstable chest wall injuries to non-operative management. In this substudy, our primary outcome was hardware-related complications and re-operation. Secondary outcomes included ventilator free days (VFDs) in the first 28 days following injury, length of ICU and hospital stay, and general health outcomes (SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores). Categorical variables are reported as frequency counts and percentages and the two groups were compared using Fisher's Exact test. Continuous data are reported as median and interquartile range and the two groups were compared using the Wilcoxon rank-sum test. From the original cohort of 207 patients, 108 had been treated surgically and had data available on the type of plate construct used. Fifty-nine patients (55%) had received fixation with non-locking plates (primarily 3.5 or 2.7 mm pelvic reconstruction plates) and 49 (45%) had received fixation with locking plates (primarily rib-specific locking plates). The two groups were similar in regard to baseline and injury characteristics. In the non-locking group, 15% of patients (9/59) had evidence of hardware loosening versus 4% (2/49 patients) in the locking group (p = 0.1). The rate of re-operation for hardware complications was 3% in the non-locking group versus 0% in the locking group (p = 0.5). No patients in either group required revision fixation for loss of reduction or nonunion. There were no differences between the groups with regard to VFDs (26.3 [19.6 – 28] vs. 27.3 [18.3 – 28], p = 0.83), length of ICU stay (6.5 [2.0 – 13.1] vs 4.1 [0 – 11], p = 0.12), length of hospital stay (17 [10 – 32] vs. 17 [10 – 24], p = 0.94) or SF-36 PCS (40.9 [33.6 – 51.0] vs 43.4 [34.1 – 49.6], p = 0.93) or MCS scores (47.8 [36.9 – 57.9] vs 46.9 [40.5 – 57.4], p = 0.95). We found no statistically significant differences in outcomes between patients who received surgical stabilization of their unstable chest wall injury when comparing non-locking plates versus locking plates. However, the rate of hardware loosening was nearly 4 times higher in the non-locking plate group and trended towards statistical significance, although re-operation related to this was less frequent. This finding is not surprising, given the inherent challenges of rib fixation including thin bones, comminution, potential osteopenia and a post-operative environment of constant motion. We believe that the increased cost of locking plate fixation in this setting is likely justifiable given these findings

Introduction. The number of total hip arthroplasties (THAs) performed per year is increasing for reasons that are not fully explained by a growing and aging population. The purpose of this study was to determine the role of patient health status as an indication for surgery and determine if patients are undergoing surgery at a better health status than in the past. Methods. To examine how pre-operative functional health status has changed over time, a systematic review and meta-analysis of the Medline, Embase, and Cochrane databases was performed in accordance with the PRISMA guidelines. Health status was assessed using the physical component summary (PCS) score from the 36-item short-form (SF-36) health survey. Only primary procedures were included; revisions were excluded. Articles were screened by two independent reviewers with conflicts resolved by consensus with a third reviewer. Meta-regression analysis was performed to determine the effect of time, patient age, and gender. Subgroup analysis was performed to assess differences between countries. Results. A total of 1,504 articles were identified. Data from 172 independent groups representing 18,644 patients recruited from 1990–2013 and identified from 107 articles were included in the final analysis. The mean pre-op PCS score was 31.2 (95% Confidence Interval: 30.5–31.9) with a 95% prediction interval of 22.6–39.8. The variance across studies was found to be statistically significant (p = 0.000) with 97.25% of this variance due to true variance. Neither year of enrolment, mean age, nor the percentage of females per group were found to have any significant effect. There were no significant differences between countries. Conclusion. Patients are undergoing THA at a similar health status to the past. Patient age and gender do not influence the functional status at which patients are indicated for surgery. There are no significant regional differences in pre-op health status

Purpose: To assess patients quality of life, pain, and functional limitations with with endstage ankle arthritis (EAA) and compared this to a similar cohort of patients with endstage hip arthritis (EHA). Methods: Preoperative data (Short Form SF36) was collected prospectively from patients (n=130) with end stage ankle arthritis and compared to a similar cohort of patients (n=130) with end stage hip arthritis. Patients with ankle arthritis were registered in the Canadian Orthopedic Foot and Ankle Society (COFAS) multi-center study investigating the clinical outcome of ankle arthroplasty and fusion and patients with hip arthritis were randomly selected from the Halifax Joint Replacement Registry Database. Results: All symptom and functional SF36 subscales for patients with EAA or EHA, were approximately two standard deviations below normal population scores. All differences between ankle and hip SF36 subscales scores were less than 4 points (40% of STD) in both direct and adjusted comparisons. A direct comparison of SF36 scores revealed that patients with EAA had significantly worse mental health according to the SF36 Mental Component Summary Score (MCS) (p= 0.0059), physical limitations with work and daily activities - role physical score (p= < 0.0001), and general health (p= 0.0004). Patients with EHA reported poorer physical function (p= 0.0007) although the Physical Component Summary Score (PCS) for the SF36 was not significant (p= 0.0510). Total Summary SF36, Physical Component Summary (PCS), bodily pain, vitality, role-emotional, social functioning, and mental health subscales were all not significantly different between cohorts (p> 0.05). Conclusions: Patients with EAA have devastating losses of quality of life, which are comparable to patients with EHA. These findings suggest that increased resources should be directed towards alleviating the severe pain and disability associated with ankle arthritis

Introduction. Total joint arthroplasty is regarded as a highly successful procedure. However, patient outcomes and implant longevity require proper alignment and prosthesis position. Computer-assisted total knee arthroplasty (TKA) has been found to improve the accuracy of component positioning and reduce rates of revision, however there remains debate whether it provides improvements in patient reported outcomes (PROs). The purpose of our study was to compare PROs between computer-assisted and conventional TKA. Methods. A retrospective review of all total knee arthroplasty patients was conducted using a single institution's FORCE database for reporting PROs. Knee Society Score (KSS), procedure satisfaction, physical component summary (PCS), and mental component summary (MCS) were compared between computer-assisted TKA and conventional TKA. Results. Computer-assisted TKA had a higher average KSS (68.8 vs 44.6), PCS (33.8 vs 30.4), and MCS (51.1 vs 47.5) compared to conventional TKA. The average procedural satisfaction (4.0 vs 4.2) was equivalent between computer-assisted and conventional TKA, respectively. Discussion. Computer-assisted TKA improves patient reported outcomes while providing equivalent satisfaction compared to conventional TKA

A significant portion of ankle arthroplasty and ankle arthrodesis procedures performed in British Columbia are funded by the public medical services plan (MSP). However, some patients are treated privately through self-pay or by the workers compensation board (WCB), with the latter two groups being more likely to receive treatment sooner. The potential effect of payer on patient-reported outcomes and reoperation rates has not been previously explored. A retrospective chart review was performed using data from the Canadian Orthopaedic Foot and Ankle Society Prospective Ankle Reconstruction Database. N=443 patients (393 MSP, 26 self-pay, 24 WCB), treated with total ankle replacement or ankle arthrodesis by three subspecialty-trained surgeons in Vancouver from 1999–2003, were analyzed. Outcomes were compared, by payer, preoperatively and at long-term follow-up (6.3 years, range 2–14 years). Function was assessed using the Ankle Osteoarthritis Scale (AOS) Total score (primary outcome) and the AOS Pain and Difficulty subscores. Expectation and satisfaction with symptoms was assessed using the Musculoskeletal Outcomes Data Evaluation and Management Scale, and physical and emotional quality of life was assessed using the Short Form-36 (SF-36) Health Survey in terms of the mental component summary (MCS) and physical component summary (PCS). Swelling and reoperation rates were also compared. AOS Total score was not significantly different between payers. WCB patients had significantly worse preoperative AOS Difficulty scores (73, 95%CI 65–80) compared to MSP (65, CI 63–67) and self-pay patients (56, CI 49–63)(p < 0 .008). Their SF-36 MCS scores were also significantly worse pre- and postoperatively (WCB: 43, CI 38–49, 45, CI 40–50, MSP: 51, CI 50–52, 51, CI 50–52, self-pay: 51, CI 46–56, 54, CI 49–58)(p < 0 .03). AOS Pain scores and SF-36 PCS scores were not different. Pre- and postoperatively, MSP patients reported more satisfaction with symptoms (1.31, CI 1.24–1.38, 3.21, CI 3.07–3.35), compared to WCB (1.13, CI 0.84–1.41, 2.83, CI 2.26–3.41) and self-pay patients (1.19, CI 0.91–1.47, 2.88, CI 2.33–3.44). Preoperatively, WCB patients had the lowest expectations (76, CI 69–84), the worst AOS Total (64, CI 57–71) and SF-36 scores (MCS 43, CI 38–49, PCS 28, CI, 25–32), and the most swelling (3.5, CI 3.1–4). Conversely, self-pay patients had the highest preoperative expectations (88, CI 81–95), the best AOS Total (53, CI 46–60) and SF-36 scores (MCS 51, CI 46–56, PCS: 34, CI 30–37) and the least swelling (3, CI 2.6–3.4). Postoperatively, WCB and self-pay patients had lower expectations met (35, CI 23–47 and 40, CI 28–51) and worse AOS Total scores (36, CI 27–45 and 35, 26–43), compared to MSP patients (Expectations: 29, CI 26–32, AOS Total: 31, CI 29–33). Reoperation rates were similar among groups. WCB patients had significantly more difficulty with symptoms prior to surgery and worse SF-36 MCS scores pre- and postoperatively. The preoperative expectations of WCB patients were lowest, while those of self-pay patients were highest. Both groups had lower expectations met postoperatively

There is clear evidence to support removal of the calcific deposit in patients with calcific tendonitis, however, there is conflicting evidence as to whether concomitant subacromial decompression (SAD) is of benefit to the patient. The aim of this study was to conduct a prospective double blind randomised control trial to assess the independent effect of SAD upon the functional outcome of arthroscopic management of calcific tendonitis. During a four year period 80 patients (power calculation was performed) were recruited to the study who presented with acute calcific tendonitis of the shoulder. Forty patients were randomised to have SAD and 40 were randomised not to have a SAD in combination with arthroscopic decompression of the calcific deposit. All surgery was performed by the senior author who was blinded to the functional assessment of the patients. There were 21 male and 59 female patients with a mean age of 48.9 (32 to 75) years. The pre-operative short form 12 physical component summary (PCS) was 39.8 and the mental component summary was 52.6, disability arm should and hand (DASH) score was 34.5, and the Constant score (CS) was 45.7. Both groups had a significant improvement in the PCS, DASH, CS at 6 weeks and at one year compared to their pre-operative scores (p<0.001). There were no significant differences demonstrated between the groups for any of the outcome measures assessed at 6 weeks or at one year. SAD should not be routinely performed as part of the arthroscopic management of acute calcific tendonitis

INTRODUCTION. Lumbar total disc replacement (TDR) is an alternative treatment to avoid fusion related adverse events, specifically adjacent segment disease. New generation of elastomeric non-articulating devices have been developed to more effectively replicate the shock absorption and flexural stiffness of native disc. This study reports 5 years clinical and radiographic outcomes, range of motion and position of the center of rotation after a viscoelastic TDR. Material and methods. This prospective observational cohort study included 61 consecutive patients with monosegmental TDR. We selected patients with intermediate functional activity according to Baecke score. Hybrid constructs had been excluded. Only cases with complete clinical and radiological follow-up at 3, 6, 12, 24 and 60 months were included. Mean age at the time of surgery was 42.8 +7.7 years-old (27–60) and mean BMI was 24.2 kg/m² +3.4 (18–33). TDR level was L5-S1 in 39 cases and L4-L5 in 22 cases. The clinical evaluation was based on Visual Analog Scale (VAS) for pain, Oswestry Disability Index (ODI) score, Short Form-36 (SF36) including physical component summary (PCS) and mental component summary (MCS) and General Health Questionnaire GHQ28. The radiological outcomes were range of motion and position of the center of rotation at the index and the adjacent levels and the adjacent disc height changes. Results. There was a significant improvement in VAS (3.3±2.5 versus 6.6±1.7, p<0.001), in ODI (20±17.9 versus 51.2±14.6, p<0.001), GHQ28 (52.6±15.5 versus 64.2±15.6, p<0.001), SF 36 PCS (58.8±4.8 versus 32.4±3.4, p<0.001) and SF 36 MCS(60.7±6 versus 42.3±3.4, p<0.001). Additional surgeries were performed in 5 cases. 3 additional procedures were initially planified in the surgical program: one adjacent L3-L5 ligamentoplasty above a L5S1 TDR and two L5S1 TDR cases had additional laminectomies. Fusion at the index level was secondary performed in 2 L4L5 TDR cases but the secondary posterior fusion did not bring improvement. In the 56 remaining patients none experienced facet joint pain. One patient with sacroiliac pain needed local injections. Radiological outcomes were studied on 56 cases (exclusion of 5 cases with additional surgeries). The mean location centers of the index level and adjacent discs were comparable to those previously published in asymptomatic patients. According to the definition of Ziegler, all of our cases remained grade 0 for disc height (within 25% of normal). Discussion. The silent block design of LP-ESP provides an interesting specificity. It could be the key factor that makes the difference regarding facets problems and instability reported with other implants experimentally or clinically. Unfortunately no other comparative TDR series are available yet in the literature. Conclusion. This series reports significant improvement in mid-term follow up after TDR which is consistent with previously published studies but with a lower rate of revision surgery and no adjacent level disease pathologies. The radiographic assessment of the patients demonstrated the quality of functional reconstruction of the lumbar spine after LP ESP viscoelastic disc replacement

Purpose. We explored the role of patients beliefs and attitudes towards their likelihood of recovery from severe physical trauma. Method. We developed and validated an instrument designed to capture the impact of patients beliefs and attitudes towards functional recovery from injury; the Somatic Pre-Occupation and Coping (SPOC) questionnaire. At six weeks post-surgical fixation, we administered the SPOC questionnaire to 359 consecutive patients with operatively managed tibial shaft fractures. We constructed multi-variable regression models to explore the association between SPOC scores and functional outcome at one year, as measured by return to work and Short Form-36 (SF-36) physical component summary (PCS) and mental component summary (MCS) scores. Results. In our adjusted regression models that included pre-injury SF-36 scores, SPOC scores at six weeks post-surgery accounted for 18% of the variation in SF-36 PCS scores and 18% of SF-36 MCS scores at one year. Our adjusted analysis found that for each 14-point increment in SPOC score (14 points being half the standard deviation of the aggregate score) at six weeks the odds of returning to work at 12 months decreased by 40% (odds ratio = 0.60; 95% CI = 0.50 to 0.73). In all models, six week SPOC scores were a far more powerful predictor of functional recovery than age, gender, fracture type, smoking status, or the presence of multi-trauma. Conclusion. The SPOC questionnaire is a valid measurement of illness beliefs and attitudes in tibial fracture patients and is highly predictive of their long-term functional recovery

Balloon kyphoplasty (BKP) is a minimally invasive treatment for vertebral fractures (VCF) aiming to correct deformity using balloon tamps and bone cement to stabilize the body. Patients with 1 - 3 non-traumatic acute VCF were enrolled within three months of diagnosis and randomly assigned to receive either BKP (N=149) or nonsurgical care (N=151). Follow-up was 2 years. The mean SF-36 physical component summary (PCS) score improved 5.1 points (95%CI, 2.8-7.4; p<0.0001) more in the kyphoplasty than the nonsurgical group at one month, the primary endpoint of the study. Kyphoplasty improved the PCS score by an average of 3.0 points (95%CI, 1.6-5.4; p=0.002) during the two-year follow-up. There was a significant interaction between treatment and follow-up time (p=0.003), indicating that the treatment effect over the year is not uniform across follow-up; a result from early improvement that persists in the kyphoplasty group whereas the nonsurgical group shows more incremental improvement over time. Overall, patients assigned to kyphoplasty also had statistically significant improvements over the two years compared to the control group in global quality of life (EQ-5D), pain relief (VAS), back disability (RMDQ) and days of limited activity (within a two-week period). There was no statistical significant difference between groups in the number of patients with adverse events or new VCF's over 24 months. Compared to the control, BKP improved quality of life and reduced back pain and disability and did not increase adverse events including the risk of new vertebral fractures over 2 years

The primary objective of this study was to determine if surgical treatment for spinal stenosis is comparable to total hip and knee arthroplasty in improving patients’ self-reported quality of life. An age, sex and time of surgery matched cohort of patients who had undergone elective primary one-two level spinal decompression (n=90) with (n=26 /90) or without fusion for spinal stenosis (n=40 with degenerative spondylolisthesis) and elective primary total hip (n=90) and knee (n = 90) arthroplasty for osteoarthritis were compared. The primary outcome measure was the preoperative and two year postoperative Medical Outcomes Study Short Form-36 (SF-36) questionnaire. There was no significant difference in the mean pre-operative Physical Component Summary (PCS) / Mental Component Summary between groups [Spine −32/43; Hip − 30/45; Knee 31/46 (p > 0.5)]. With the exception of the knee MCS (p=0.2), postoperative scores were significantly improved for all groups [Spine −40/53; Hip − 43/51; Knee 39/48 (p < 0.001)]. Overall the hip surgery had the great impact on PCS and the spine surgery on MCS. Studies have shown the significant impact on overall patient quality of life and cost-effectiveness of primary total joint arthroplasty. The results of this unique study show that surgical intervention for spinal stenosis has a similar positive effect at two year follow up. This study provides data that supports the need advocacy regarding waiting time initiatives and surgical resources for the treatment of patients with symptomatic spinal stenosis with a similar demographic to those with primary OA of the hip or knee

Purpose: The primary objective of this study was to determine if surgical treatment for spinal stenosis is comparable to total hip arthroplasty in improving patients’ self-reported quality of life. Methods: An age, sex and time of surgery matched cohort of patients who had undergone elective primary 1–2 level spinal decompression (n=90) with (n=30/90) or without fusion for spinal stenosis (n=40 with degenerative spondylolisthesis) and elective primary total hip arthroplasty for osteoarthritis (n=90) were compared. The primary outcome measure was the preoperative and one year postoperative Medical Outcomes Study Short Form-36 (SF-36) questionnaire. Results: The mean Physical Component Summary (PCS) / Mental Component Summary (MCS) for the stenosis compared to hip patients were 32.0/43.3 vs. 30.5/46.2 preoperatively (analysis between groups: p = 0.2/0.1) and 39.1/47.3 vs.44.1/46.1 postoperatively (analysis between groups: p = 0.003/0.4). The pre- and postoperative PCS significantly improved for both groups (p < 0.0001);however, the pre- and postoperative MCS improved in the stenosis group only (p = 0.04). Conclusions: Studies have shown the significant impact on overall patient quality of life and cost-effectiveness of primary total hip arthroplasty. The results of this unique study show that surgical intervention for spinal stenosis also has a very positive overall effect on patients’ self-reported quality of life at one year follow up. This study provides data that supports the need for a long term prospective study and advocacy regarding waiting time initiatives and surgical resources for the treatment of patients with symptomatic spinal stenosis with a similar demographic to those with primary OA of the hip

Background. Vertebral body compression fractures (VCFs) impair quality of life (QOL) and increase patient morbidity and mortality. The international, multicentre, randomised, controlled Fracture Reduction Evaluation (FREE) trial was initiated to compare effectiveness and safety of Balloon kyphoplasty (BKP) to non-surgical management (NSM) for the treatment of acute painful VCFs. We describe the primary endpoint of the ongoing 2-year study. Methods. Patients with 1-3 non-traumatic VCFs (< 3 months old) were randomised to either BKP or NSM. The primary endpoint was the change in QOL as measured by the SF-36 Health Survey Physical Component Summary (PCS) at one month, and device/procedure-related safety. Secondary endpoints included SF-36 subscales, the EQ-5D, self-reported back pain and function using the Roland Morris Disability Questionnaire (RMDQ). All patients were given osteoporosis medical therapy. Results. Among the BKP (N=149) and NSM (N=151) cohorts, mean patient age was 73 years and 77% were female. Most patients had VCFs due to primary osteoporosis; 8 patients due to corticosteroid-induced osteoporosis, and 4 had cancer-related fractures. Thirty-nine BKP (26%) and 36 NSM (24%) patients had >1 VCF treated. At one month follow-up, the mean improvement in the PCS was in favour of BKP over NSM (p<0.0001). All physical component SF-36 subscales and the total EQ-5D score were significantly improved for BKP compared to NSM. Mean improvements in back pain at 7 days and 1 month were significantly greater for BKP compared to NSM (p<0.0001 at both time points). The improvement in RMDQ for BKP over NSM was also significant (p<0.0001). There was one soft tissue haematoma and urinary tract infection, with no bone cement-related serious adverse events. Conclusions. Compared to non-surgical management, balloon kyphoplasty demonstrated superior short-term pain, function and quality of life outcomes with no difference in serious adverse events for the treatment of acute, painful vertebral compression fractures.

Background: This meta-analysis aims to evaluate the quality of life in post traumatic amputees in comparison with a limb salvage group, using peer-reviewed studies in these areas. Methods: Electronic databases were searched for studies on lower limb amputation and limb reconstruction following trauma. A manual review of the literature and abstracts was also conducted. Only studies having more than 24 months of follow up, and those using generic scales using physical and psychological parameters (SIP or SF36), were included. Two reviewers performed the search, inclusion, and data extraction independently. Results: 214 studies were identified after extensive searching, Eleven studies fulfilled all the inclusion criteria, reviewing the outcomes of 1874 patients including 899 cases of amputation and 975 cases of reconstruction. Outcome assessments were based on two generic scales of measurement for quality of life, namely SIP or SF 36. In the studies using SF36, the mean Physical Component Summary (PCS) for the amputation group was 39.76 +/−7.06 and mean Mental Component Summary (MCS) was 52.05+/−3.39. The mean PCS for the reconstruction group was 38.5+/−0.78 and the mean MCS was 50.76 +/− 3.09. The mean physical SIP score for amputation was 13.033 with SEM of 3.048, and the psychological SIP score was 15.953 with SEM of 1.153. The mean Physical SIP for reconstruction was 10.686 with SEM of 1.034 and the psychological SIP was 10.754 with SEM of 0.647. The Unpaired t test was used to compare the outcomes of amputation and reconstruction, studies using SF36 and SIP scores were compared independently. Our results show that physical morbidity in both groups is not significantly influenced by the modality of surgical intervention, but there is a statistically significant difference noted in psychological morbidity, the group with reconstruction being better. These results were consistent in studies using either of the two generic scales namely, SF36 or SIP scores. Conclusion: This meta-analysis provides evidence that limb reconstruction in lower limb trauma yields better psychological outcomes without significant difference in physical morbidity compared to amputation

Introduction: A consecutive series of patients with adolescent idiopathic scoliosis, treated between 1968 and 1977 before 21 years of age, either with distraction and fusion using Harrington rods (ST, n=156; 145 females and 11 males) or with brace (BT, n=127; 122 females and 5 males) were followed at least twenty years after completion of the treatment to determine the long-term outcome in terms of health related quality of life (HRQL) in patients treated for adolescent idiopathic scoliosis. No results on long term outcome of HRQL have previously been presented for this group of patients. Methods and Results: Ninety-four per cent of ST and 91% of BT patients filled in a questionnaire comprising the SF-36, Psychological General Well-Being Index (PGWB), Oswestry Disability Back Pain Questionnaire, parts of SRS/MODEM’s questionnaire and study-specific questions concerning the treatment, as a part of an unbiased personal follow-up examination. An age and sex-matched control group of 100 persons was randomly selected and subjected to the same examinations. There were no differences in terms of sociodemographic data between the groups. Both ST and BT patients had a slightly, but significantly reduced physical function using the SF-36 subscales, SF-36/Physical Component Summary (PCS) score as well as the Oswestry Disability Back Pain Questionnaire compared to the controls. Neither the mental subscales and the Mental Component Summary (MCS) score of SF-36 nor the PGWB index showed any significant difference between the groups. Forty-nine per cent of ST, 34% of BT and 15% of controls admitted limitation of social activities due to their back, (p< 0.001 ST vs. controls, BT vs. controls p= 0.010, and p=0.024 n.s. ST vs. BT), mostly due to difficulties to physically participate in activities or selfconsciousness about appearance. Pain was a minor reason for limitation. No correlation could be found between the outcome scores and curve size after treatment, curve type, total treatment time or age at completed treatment. Conclusions: Patients treated for adolescent idiopathic scoliosis were found to have approximately the same HRQL as the general population. A minority of the patients (4%) had a severely decreased psychological well-being and a few (1.5%) were physically severely disabled due to the back

No studies have focused on the relationships between pathological changes in the subsynovial connective tissue and clinical or neurophysiological findings in patients suffering from carpal tunnel syndrome (CTS). Twenty-five consecutive patients (mean age 58.8±10 years; range 39–79) operated on for idiopathic CTS were evaluated before surgery and six month later. The indication for surgery was the presence of symptoms despite a three-month trial of conservative management. Mean duration of symptoms was 5.3±4.6 years (range 0.5–15). On admission, demographic and medical history data were recorded from all the patients. Subsequently, patients underwent preoperative physical examination and an outcome set including a mixed historic and objective scale (Hi-Ob), the Italian version of the Boston Carpal Tunnel Questionnaire (BCTQ) and the official Italian version of the SF-36 questionnaire was administered. The baseline diagnostic work-up included standard radiographs of the hand and wrist, blood examination and neurophysiological testing. Patients underwent open carpal tunnel release and thickened synovium from the flexor digitorum superficialis tendons was harvested. The number of cells, the number, diameter and density of the vessels, and the total surface of angiogenetic foci were measured. On the SF-36 questionnaire, the preoperative physical component summary (PCS) and mental component summary (MCS) scores averaged 36.5±4.2 and 40.8±5.7, respectively; at follow they averaged 47±10.2 and 46.8±7.3, respectively, with significant improvement for PCS. Preoperative and postoperative Hi-Ob scores measured 3.4±0.5 and 1.3±0.5, respectively. The BCTQ symptoms scale averaged 3.9±0.3 before surgery and 1.5±0.2 at follow up, whereas the BCQT functional status scale measured 3.4±0.5 at baseline and 1.4±0.3 six months after the operation. Univariate and multiple linear regression analysis were used to evaluate relationships between explanatory variables and outcomes. A high grade of preoperative neurophysiologic impairment was in direct relationship with the improvement in SF-36’s PCS score obtained with surgery (p=0.017). Conversely, no association was detected between neurophysiological grade and the postoperative improvement in Hi-Ob or BCQT scales. The univariate analysis showed a trend toward a direct association between number of vessels in the synovium and the improvement of BCTQ symptoms at follow-up (p=0.06). This trend was confirmed to a lesser extent at the multivariate analysis. With the numbers available, no other histological parameters were associated with the baseline neurophysiological findings or clinical outcomes. Although our results should be interpreted cautiously due to the small sample size, we conclude that the severity of pathological changes in the flexor synovium during CTS do not influence the baseline severity or outcome of this syndrome

Amputation is one of the most feared injuries in service personnel, particularly a worry that it will mean the end of their military career. The aim of this study was to determine the outcome, in relation to military service in UK military amputees. UK service personnel who sustain an amputation undergo rehabilitation and prosthetic limb fitting at the Defence Medical Rehabilitation Centre Headley Court. This includes a realistic assessment of their employment capabilities, and they are graded by a Functional Activity Assessment (FAA). FAA ranges from 1 (fully fit) to 5 (unfit all duties). In addition the Short Form-36 Health Survey (SF-36) is completed on initial admission and at follow-up. We reviewed this information to determine the outcome of military amputees. We identified 53 casualties who had sustained amputations. 8 had sustained an upper limb amputation, 41 a lower limb amputation, and 4 had sustained both an upper and lower limb amputation. 9 patients (including 1 Reservist) have left the forces by medical discharge, with the remaining 44 continuing to serve. 32 of the 44 have returned to work, albeit at a lower level. 49 patients have FAA grades and are at least 6 months post-injury. No patients were graded as FAA 1, 8 as FAA 2 (Fit for Trade and fit for restricted General or Military Duties), 18 as FAA 3 (Unfit for Trade but fit for restricted General or Military Duties), 18 as FAA 4 (Unfit for all but Sedentary Duties) and 5 as FAA 5. All bilateral and triple amputees were FAA 4 or 5. Other injuries such as blindness, severe brain injury or mental health issues also increased the FAA. Of the 32 patients who have returned to work, 8 are FAA 2, 12 are FAA 3, 11 are FAA 4, and 1 has not been graded. SF-36 data was available in 40 patients, available as paired scores for 34. The mean time between SF-36 scoring was 6.7 months (range 0.2 – 17.4). The mean SF-36 scores for Physical Component Summary (PCS) increased from 34.40 (SD 9.3) to 42.06 (SD 11.1), with Mental Component Summary (MCS) 52.01 (SD12.9) remaining similar at 52.92 (SD 12.0). Pre- and post-rehabilitation PCS scores improved with rehabilitation (p=0.0003). MCS scores were similar in these patients to the normal population, 50 (SD 10). No differences could be found within the unilateral lower limb amputation group regarding amputation level (trans-tibial, through-knee disarticulation, trans-femoral) and SF-36 scoring. Furthermore due to the low numbers, no conclusion could be made comparing the unilateral lower limb amputation group with the bilateral lower limb group, the unilateral lower limb plus upper limb, the bilateral lower limb and upper limb (trilateral), and the isolated upper limb groups. This study is the first to report the outcomes, with regards to return to work, of the UK military amputee population injured in Afghanistan and Iraq. There is an almost even distribution of FAA score between 2, 3, and 4 for those back at work. Level of amputation and SF-36 scores do not seem to correlate, partly due to other injuries sustained that confound the patients’ perception of their health. SF-36 PCS scores increase significantly with rehabilitation, whilst MCS remain similar to the normal population

Oxidized Zirconium (Oxinium, Smith & Nephew, Inc., Memphis, TN) is a relatively new material that features an oxidized ceramic surface chemically bonded to a tough metallic substrate. This material has demonstrated the reduced polyethylene wear characteristics of a ceramic, without the increased risk of implant fracture. The purpose of the current investigation was to assess clinical outcomes following primary total hip arthroplasty with Oxinium versus Cobalt Chrome femoral heads. One hundred uncemented primary total hip arthroplasty procedures were prospectively performed in 100 patients. There were 52 males and 48 females with mean age at the time of surgery of 51 years (SD 11, range, 19–76). Using a process of sealed envelope randomization, patients were divided into 2 groups. Each group contained fifty patients. Those in group 1 received an Oxinium femoral head (OX), while those in group 2 a cobalt-chrome femoral head (CC). The current study reports clinical outcome measures for both the OX and CC groups at a minimum follow-up of 2 years postoperatively. At the time of latest follow-up, stem survival for both groups was 98%. There was a significant improvement in all clinical outcome scores between preoperative and 2 year postoperative time periods for both bearing groups (p< 0.003). There were no significant differences between bearing groups for any of the clinical outcome scores at final follow-up (p> 0.159). Mean Harris Hip Scores at 2 years postoperatively were 92 and 92.5 for OX and CC, respectively (range; 65–100 OX, 60–100 CC). For SF-12, both the Physical Component Summary Scale (PCS) and the Mental Component Summary Scale (MCS) are reported. Mean PCS scores at final follow-up were 45.2 and 49.21 for OX and CC (range; 27.1–56.7 OX, 26.3–61.8 CC). Mean MCS scores were 53.8 and 52.57 for OX and CC (range; 39.2–65.5 OX, 34.3–64 CC). Mean final WOMAC scores are reported as 84.9 and 87 for OX and CC, respectively. The current data suggest that total hip arthroplasty utilizing Oxinium femoral heads is safe and effective. Additional follow-up of the current cohort will be performed in order to fully assess mid-to long-term clinical outcomes
