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.

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.

Aims. Acetabular fractures are associated with long-term morbidity. Our prospective cohort study sought to understand the recovery trajectory of this injury over five years. Methods. Eligible patients at a level I trauma centre were recruited into a longitudinal registry of surgical acetabular fractures between June 2004 and August 2019. Patient-reported outcome measures (PROMs), including the 36-Item Short Form Health Survey (SF-36) physical component summary (PCS), were recorded at baseline pre-injury recall and six months, one year, two years, and five years postoperatively. Comparative analyses were performed for elementary and associated fracture patterns. The proportion of patients achieving minimal clinically important difference (MCID) was determined. The rate of, and time to, conversion to total hip arthroplasty (THA) was also established. Results. We recruited 251 patients (253 fractures), with a 4:1 male to female ratio and mean age of 46.1 years (SD 16.4). Associated fracture patterns accounted for 56.5% of fractures (n = 143). Trajectory analysis showed all timepoints had significant disability versus baseline, including final follow-up (p < 0.001). Elementary fractures had higher SF-36 PCS at six months (p = 0.023) and one year (p = 0.007) compared to associated fractures, but not at two years (p = 0.135) or five years (p = 0.631). The MCID in SF-36 PCS was observed in 37.3% of patients (69/185) between six months and one year, 26.9% of patients (39/145) between one and two years, and 23.3% of patients (20/86) between two and five years, highlighting the long recovery potential of these injuries. A significant proportion of patients failed to attain the MCID after five years (38.1%; 40/105). Conversion to THA occurred in 13.1% of patients (11/110 elementary and 22/143 associated fractures). Approximately two-thirds of THAs (21/33 patients; 63.6%) were performed within two years of index surgery. Conclusion. Acetabular fractures significantly impact physical function. Recovery trajectory is often elongated beyond one year, with two-thirds of our patients displaying persistent clinically relevant long-term disability.

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

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

Aims. Acetabular fractures in older adults lead to a high risk of mortality and morbidity. However, only limited data have been published documenting functional outcomes in such patients. The aims of this study were to describe outcomes in patients aged 60 years and older with operatively managed acetabular fractures, and to establish predictors of conversion to total hip arthroplasty (THA). Methods. We conducted a retrospective, registry-based study of 80 patients aged 60 years and older with acetabular fractures treated surgically at The Alfred and Royal Melbourne Hospital. We reviewed charts and radiological investigations and performed patient interviews/examinations and functional outcome scoring. Data were provided by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR). Survival analysis was used to describe conversion to THA in the group of patients who initially underwent open reduction and internal fixation (ORIF). Multivariate regression analyses were performed to identify factors associated with conversion to THA. Results. Seven patients (8.8%) had died at a median follow-up of 18 months (interquartile range (IQR) 12 to 25), of whom four were in the acute THA group. Eight patients (10%) underwent acute THA. Of the patients who underwent ORIF, 17/72 (23.6%) required conversion to THA at a median of 10.5 months (IQR 4.0 to 32.0) . After controlling for other factors, transport-related cases had an 88% lower rate of conversion to THA (hazard ratio (HR) 0.12, 95% confidence interval (CI) 0.02 to 0.91). Mean standardized Physical Component Summary Score (PCS-12) of the 12-Item Short Form Health Survey (SF-12) was comparable with the general population (age-/sex-matched) by 12 to 24 months. Over half of patients working prior to injury (14/26) returned to work by six months and two-thirds of patients (19/27) by 12 months. Conclusion. Patients over 60 years of age managed operatively for displaced acetabular fractures had a relatively high mortality rate and a high conversion rate to THA in the ORIF group but, overall, patients who survived had mean PCS-12 scores that improved over two years and were comparable with controls.

Aims. While patients with psychological distress have poorer short-term outcomes after total knee arthroplasty (TKA), their longer-term function is unknown. We aimed to 1) assess the influence of preoperative mental health status on long-term functional outcomes, quality of life, and patient satisfaction; and 2) analyze the change in mental health after TKA, in a cohort of patients with no history of mental health disorder, with a minimum of ten years’ follow-up. Methods. Prospectively collected data of 122 patients undergoing primary unilateral TKA in 2006 were reviewed. Patients were assessed pre- and postoperatively at two and ten years using the Knee Society Knee Score (KSKS) and Function Score (KSFS); Oxford Knee Score (OKS); and the Mental (MCS) and Physical Component Summary (PCS) which were derived from the 36-Item Short-Form Health Survey questionnaire (SF-36). Patients were stratified into those with psychological distress (MCS < 50, n = 51) and those without (MCS ≥ 50, n = 71). Multiple regression was used to control for age, sex, BMI, Charlson Comorbidity Index (CCI), and baseline scores. The rate of expectation fulfilment and satisfaction was compared between patients with low and high MCS. Results. There was no difference in the mean KSKS, KSFS, OKS, and SF-36 PCS at two years or ten years after TKA. Equal proportions of patients in each group attained the minimal clinically important difference for each score. Psychologically distressed patients had a comparable rate of satisfaction (91.8% (47/51) vs 97.1% (69/71); p = 0.193) and fulfilment of expectations (89.8% vs 97.1%; p = 0.094). The proportion of distressed patients declined from 41.8% preoperatively to 29.8% at final follow-up (p = 0.021), and their mean SF-36 MCS improved by 10.4 points (p < 0.001). Conclusion. Patients with poor mental health undergoing TKA may experience long-term improvements in function and quality of life that are comparable to those experienced by their non-distressed counterparts. These patients also achieved a similar rate of satisfaction and expectation fulfilment. Undergoing TKA was associated with improvements in mental health in distressed patients, although this effect may be due to residual confounding.

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

Aims. The aim of this study was to determine the trajectory of recovery following fixation of tibial plateau fractures up to five-year follow-up, including simple (Schatzker I-IV) versus complex (Schatzker V-VI) fractures. Patients and Methods. Patients undergoing open reduction and internal fixation (ORIF) for tibial plateau fractures were enrolled into a prospective database. Functional outcome, using the 36-Item Short Form Health Survey Physical Component Summary (SF-36 PCS), was collected at baseline, six months, one year, and five years. The trajectory of recovery for complex fractures (Schatzker V and VI) was compared with simple fractures (Schatzker I to IV). Minimal clinically important difference (MCID) was calculated between timepoints. In all, 182 patients were enrolled: 136 (74.7%) in simple and 46 (25.3%) in complex. There were 103 female patients and 79 male patients with a mean age of 45.8 years (15 to 86). Results. Mean SF-36 PCS improved significantly in both groups from six to 12 months (p < 0.001) and one to five years (simple, p = 0.008; complex, p = 0.007). In both groups, the baseline scores were not reached at five years. The SF-36 PCS was significantly higher in the simple group compared with the complex group at both six months (p = 0.007) and 12 months (p = 0.01), but not at five years (p = 0.17). Between each timepoint, approximately 50% or more of the patients in each group achieved an MCID in their score change, indicating a significant clinical change in condition. The complex group had a much larger drop off in the first six months, with comparable proportions achieving MCID at the subsequent time intervals. Conclusion. Tibial plateau fracture recovery was characterized overall by an initial decline in functional outcome from baseline, followed by a steep improvement from six to 12 months, and ongoing recovery up to five years. In simple patterns, patients tended to achieve a higher functional score by six months compared with the complex patterns. However, comparable functional scores between the groups achieved only at the five-year point suggest later recovery in the complex group. Function does not improve to baseline by five years in either group. This information is useful in counselling patients about the course of prospective recovery.

Aims. The purpose of this study was to investigate the risk of additional surgery in the lumbar spine and to describe long-term changes in patient-reported outcomes after surgery for lumbar disc herniation in adolescents and young adults. Patients and Methods. We conducted a retrospective study design on prospectively collected data from a national quality register. The 4537 patients were divided into two groups: adolescents (≤ 18 years old, n = 151) and young adults (19 to 39 years old, n = 4386). The risk of additional lumbar spine surgery was surveyed for a mean of 11.4 years (6.0 to 19.3) in all 4537 patients. Long-term patient-reported outcomes were available at a mean of 7.2 years (5.0 to 10.0) in up to 2716 patients and included satisfaction, global assessment for leg and back pain, Oswestry Disability Index, visual analogue scale for leg and back pain, EuroQol five-dimension questionnaire (EQ-5D), and 36-Item Short-Form Health Survey (SF-36) Mental Component Summary and Physical Component Summary scores. Statistical analyses were performed with Cox proportional hazard regression, chi-squared test, McNemar’s test, Welch–Satterthwaite t-test, and Wilcoxon’s signed-rank test. Results. Any type of additional lumbar spine surgery was seen in 796 patients (18%). Surgery for lumbar disc herniation accounted for more than half of the additional surgeries. The risk of any additional surgery was 0.9 (95% confidence interval (CI) 0.6 to 1.4) and the risk of additional lumbar disc herniation surgery was 1.0 (0.6 to 1.7) in adolescents compared with the young adult group. Both age groups improved their patient-reported outcome data after surgery (all p < 0.001). Changes between short- (mean 1.9 years (1.0 to 2.0)) and long-term follow-up (mean 7.2 years (5.0 to 10.0)) were small. Conclusion. The risk of any additional lumbar spine surgery and additional lumbar disc herniation surgery was similar in adolescents and young adults. All patient-reported outcomes improved from preoperative to the short-term follow-up, while no likely clinically important differences between the short- and long-term follow-up were seen within both groups.

Aims. The primary aim of this study was to quantify the improvement in patient-reported outcome measures (PROMs) following total hip arthroplasty (THA), as well as the extent of any deterioration through the seven-year follow-up. The secondary aim was to identify predictors of PROM improvement and deterioration. Patients and Methods. A total of 976 patients were enrolled into a prospective, international, multicentre study. Patients completed a battery of PROMs prior to THA, at three months post-THA, and at one, three, five, and seven-years post-THA. The Harris Hip Score (HHS), the 36-Item Short-Form Health Survey (SF-36) Physical Component Summary (PCS), the SF-36 Mental Component Summary (MCS), and the EuroQol five-dimension three-level (EQ-5D) index were the primary outcomes. Longitudinal changes in each PROM were investigated by piece-wise linear mixed effects models. Clinically significant deterioration was defined for each patient as a decrease of one half of a standard deviation (group baseline). Results. Improvements were noted in each PROM between the preoperative and one-year visits, with one-year values exceeding age-matched population norms. Patients with difficulty in self-care experienced less improvement in HHS (odds ratio (OR) 2.2; p = 0.003). Those with anxiety/depression experienced less improvement in PCS (OR -3.3; p = 0.002) and EQ-5D (OR -0.07; p = 0.005). Between one and seven years, obesity was associated with deterioration in HHS (1.5 points/year; p = 0.006), PCS (0.8 points/year; p < 0.001), and EQ-5D (0.02 points/year; p < 0.001). Preoperative difficulty in self-care was associated with deterioration in HHS (2.2 points/year; p < 0.001). Preoperative pain from other joints was associated with deterioration in MCS (0.8 points/year; p < 0.001). All aforementioned factors were associated with clinically significant deterioration in PROMs (p < 0.035), except anxiety/depression with regard to PCS (p = 0.060). Conclusion. The present study finds that patient factors affect the improvement and deterioration in PROMs over the medium term following THA. Special attention should be given to patients with risk factors for decreased PROMs, both preoperatively and during follow-up. Cite this article: Bone Joint J 2019;101-B:768–778

Aims. This study reports the mid-term results of total hip arthroplasty (THA) performed using a monoblock acetabular component with a large-diameter head (LDH) ceramic-on-ceramic (CoC) bearing. Patients and Methods. Of the 276 hips (246 patients) included in this study, 264 (96%) were reviewed at a mean of 67 months (48 to 79) postoperatively. Procedures were performed with a mini posterior approach. Clinical and radiological outcomes were recorded at regular intervals. A noise assessment questionnaire was completed at last follow-up. Results. There were four re-operations (1%) including one early revision for insufficient primary fixation (0.4%). No hip dislocation was reported. The mean University of California, Los Angeles (UCLA) activity score, 12-Item Short-Form Health Survey (SF-12) Mental Component Summary (MCS) score, SF-12 Physical Component Summary (PCS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and Forgotten Joint Score (FJS) were 6.6 (2 to 10), 52.8 (25.5 to 65.7), 53.0 (27.2 to 66.5), 7.7 (0 to 63), and 88.5 (23 to 100), respectively. No signs of loosening or osteolysis were observed on radiological review. The incidence of squeaking was 23% (n = 51/225). Squeaking was significantly associated with larger head diameter (p < 0.001), younger age (p < 0.001), higher SF-12 PCS (p < 0.001), and UCLA scores (p < 0.001). Squeaking did not affect patient satisfaction, with 100% of the squeaking hips satisfied with the surgery. Conclusion. LDH CoC THAs have demonstrated excellent functional outcomes at medium-term follow-up, with very low revision rate and no dislocations. The high incidence of squeaking did not affect patient satisfaction or function. LDH CoC with a monoblock acetabular component has the potential to provide long term implant survivorship with unrestricted activity, while avoiding implant impingement, liner fracture at insertion, and hip instability.

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

Aims. The aim of this study was to determine the efficacy of repeat epidural steroid injections as a form of treatment for patients with insufficiently controlled or recurrent radicular pain due to a lumbar or cervical disc herniation. Patients and Methods. A cohort of 102 patients was prospectively followed, after an epidural steroid injection for radicular symptoms due to lumbar disc herniation, in 57 patients, and cervical disc herniation, in 45 patients. Those patients with persistent pain who requested a second injection were prospectively followed for one year. Radicular and local pain were assessed on a visual analogue scale (VAS), functional outcome with the Oswestry Disability Index (ODI) or the Neck Pain and Disability Index (NPAD), as well as health-related quality of life (HRQoL) using the 12-Item Short-Form Health Survey questionnaire (SF-12). Results. A second injection was performed in 17 patients (29.8%) with lumbar herniation and seven (15.6%) with cervical herniation at a mean of 65.3 days . (sd. 46.5) and 47 days . (sd. 37.2), respectively, after the initial injection. All but one patient, who underwent lumbar microdiscectomy, responded satisfactorily with a mean VAS for leg pain of 8.8 mm . (sd. 10.3) and a mean VAS for arm pain of 6.3 mm . (. sd. 9) one year after the second injection, respectively. Similarly, functional outcome and HRQoL were improved significantly from the baseline scores: mean ODI, 12.3 (. sd. 12.4; p < 0.001); mean NPAD, 19.3 (. sd. 24.3; p = 0.041); mean SF-12 physical component summary (PCS) in lumbar herniation, 46.8 (. sd. 7.7; p < 0.001); mean SF-12 PCS in cervical herniation, 43 (. sd. 6.8; p = 0.103). Conclusion. Repeat steroid injections are a justifiable form of treatment in symptomatic patients with lumbar or cervical disc herniation whose symptoms are not satisfactorily relieved after the first injection.

Introduction. The objective of this study was to verify the long-term outcome of transtrochanteric anterior rotational osteotomy (ARO) for osteonecrosis of the femoral head (ONFH) in young patients with systemic lupus erythematosus (SLE). Methods. Consecutive series of 21 symptomatic ONFH patients with SLE (33 hips), aged 20 to 40 years, underwent ARO between 1980 and 1988. We reviewed the cases of 16 patients (25 hips), which represents a 76% rate of follow-up. Patients included 4 men and 12 women who had a mean age of 29 years at the time of surgery. A Kaplan-Meier curve was used for the survivorship analysis of ARO. Patients with surviving hips were evaluated by the modified Oxford hip score and the Medical Outcomes Study Short Form 36 (SF-36). Results. Twelve hips in 8 patients survived at the final follow-up. The average length of surviving was 25 years (range, 20 to 27 years). Three patients (6 hips) had died of unrelated causes without any conversion at the mean time of 9 years after ARO. Based on Kaplan-Meier analysis with the end point defined as any conversion, the survival rate at 25 years was 73.7% (95% confidence interval, 53.9 to 93.5%). Based on the classification of the modified Oxford hip score, 5 hips were classified as excellent, 2 hips were good, and the remaining 5 hips were fair. The average SF-36 physical component summary score was 34 points and the average mental component summary score was 46 points. The physical component summary scores of 3 patients (53.0, 56.6, 57.1) exceeded the level of the Japanese population norm. Conclusion. In ONFH patients with SLE, ARO achieved a 73.7% survival rate at 25 years

Persistent post-surgical pain and associated disability are common after a traumatic fracture repair. Preliminary evidence suggests that patients' beliefs and perceptions may influence their prognosis. We sought to explore this association. We used data from the Fluid Lavage of Open Wounds trial to determine, in 1560 open fracture patients undergoing surgical repair, the association between Somatic PreOccupation and Coping (captured by the SPOC questionnaire) and recovery at 1 year. Of the 1218 open fracture patients with complete data available for analysis, 813 (66.7%) reported moderate to extreme pain at 1 yr. The addition of SPOC scores to an adjusted regression model to predict persistent pain improved the concordance statistic from 0.66 to 0.74, and found the greatest risk was associated with high SPOC scores [odds ratio: 5.63, 99% confidence interval (CI): 3.59–8.84, absolute risk increase 40.6%, 99% CI: 30.8%, 48.6%]. Thirty-eight per cent (484 of 1277) reported moderate to extreme pain interference at 1 yr. The addition of SPOC scores to an adjusted regression model to predict pain interference improved the concordance statistic from 0.66 to 0.75, and the greatest risk was associated with high SPOC scores (odds ratio: 6.06, 99% CI: 3.97–9.25, absolute risk increase: 18.3%, 95% CI: 11.7%, 26.7%). In our adjusted multivariable regression models, SPOC scores at 6 weeks post-surgery accounted for 10% of the variation in short form-12 physical component summary scores and 14% of short form-12 mental component summary scores at 1 yr. Amongst patients undergoing surgical repair of open extremity fractures, high SPOC questionnaire scores at 6 weeks post-surgery were predictive of persistent pain, reduced quality of life, and pain interference at 1 yr

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

The aim of this study was to compare the outcome of bilateral sequential total ankle replacement (TAR) with that of unilateral TAR. We reviewed 23 patients who had undergone sequential bilateral TAR under a single anaesthetic and 46 matched patients with a unilateral TAR. There were no significant pre-operative differences between the two groups in terms of age, gender, body mass index, American Society of Anaesthesiologists classification and aetiology of the osteoarthritis of the ankle. Clinical and radiological follow-up was carried out at four months, one and two years. After four months, patients with simultaneous bilateral TAR reported a significantly higher mean pain score than those with a unilateral TAR. The mean American Orthopaedic Foot and Ankle Society hindfoot score and short-form 36 physical component summary score were better in the unilateral group. However, this difference disappeared at the one-and two-year follow-ups. Bilateral sequential TAR under one anaesthetic can be offered to patients with bilateral severe ankle osteoarthritis. However, they should be informed of the long recovery period

Purpose: Deciding how to allocate scarce surgical resources is a worldwide issue. These decisions can be especially difficult when considering procedures aimed primarily at improving functional quality of life, such as lower extremity joint replacement (LEJR) surgery, and those procedures that can be perceived primarily as life preserving but should also have an impact on physical function, such as coronary artery bypass graft (CABG) surgery. A comparison of the functional outcomes of these two different procedures may provide further evidence to guide resource allocation decisions. The purpose of this study is to compare patient-reported functional outcomes following CABG and LEJR surgery using standardized, validated outcome metrics. Method: A retrospective review of prospectively collected pre and post-operative health related quality of life (SF-36) measures from patients undergoing elective CABG and elective LEJR surgery in an academic surgical center. The sample included 112 CABG patients who were matched with LEJR patients based on gender and age. Results: The mean age in the CABG group was 63 years, in the LEJR group 64 years. Seventy eight percent (78%) of the patients were male. Pre-operatively, CABG patients reported statistically higher (p< 0.05) Physical Functioning, less Bodily Pain, and superior Physical Component summary SF-36 scores compared to the LEJR group. However, their pre-operative General Health scores were statistically lower. Surgery resulted in a general improvement in all SF-36 scales and summary scores for all patients, with statistically significant improvements in Bodily Pain and General Health Scores occurring in both groups. Interestingly, the improvement in Bodily Pain score was greater for the LEJR group than the CABG group, whereas the improvement in General Health Score was greater in the CABG group. However the pre-operative pattern of statistically better Physical Functioning, Bodily Pain and Physical Component summary SF-36 scores in the CABG group, and superior General Health scores in the LEJR group remained following surgery. Conclusion: It appears that, despite being matched for age and gender, significant pre-operative general health differences exist between CABG and LEJR patients that persist post-operatively. While surgery does result in significant improvements for both groups, CABG patients enjoy greater improvement in General Health scores while LEJR patients benefit from greater improvements in Bodily Pain scores. Further research is currently underway to examine how these differences are reflected in disease-specific scores and in health care resource utilization

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

The outcome in 83 patients with congenital clubfoot was evaluated at a mean age of 64 years using three validated questionnaires assessing both quality of life (short-form (SF)-36 and EQ-5D) and foot and ankle function (American Academy of Orthopaedic Surgeons (AAOS) Foot and Ankle questionnaire). In SF-36, male patients scored significantly better than male norms in seven of the eight domains, whereas female patients scored significantly worse than female norms in two of the eight. Male patients scored better than male norms in both the EQ-5D index (p = 0.027) and visual analogue scale (VAS) (p = 0.013), whereas female patients scored worse than female norms in the VAS (p < 0.001). Both male and female patients had a significantly worse outcome on the AAOS Core Scale than did norms. There was a significant correlation for both genders between the SF-36 Physical Component Summary Score and the AAOS Core Scale. The influence on activities of daily life was limited to foot and ankle problems in all patients, and in females there was an adverse effect in physical aspects of quality of life

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

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

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

Purpose. There is no clear definition of a critical sized defect of the tibia. We defined it as a fracture gap at least one centimeter in length and involving over 50% of the cortical diameter. We explored if the presence of a critical-sized defect predicted reoperation, and which other factors predict reoperation in patients with the critical defect. The patient based outcomes of these patients were compared to patients without a critical defect. Method. Patients enrolled in the SPRINT trial with a critical sized defect were evaluated for secondary interventions to gain union. Other factors predicting the need for reoperation were studied. We also compared the patients with critical sized defects to the larger cohort of patients without a defect with respect to demographics, injury mechanism, fracture characteristics, and patient-based outcome. Results. Tibial diaphyseal defects of greater than or equal to one centimeter and >50% cortical circumference healed without additional surgery in 47% of cases. Fewer reoperations were required in patients treated with a reamed nail (p=0.04). The mean of the SF-36 physical component summary in patients with a critical sized defect was poorer than the overall cohort (p=0.02, difference = 5.2, 95% confidence interval 0.8 to 9.6). Conclusion. This definition of a critical sized defect is not critical in terms of predicting reoperation, as 47% of cases healed without additional intervention. However, patients with these bone defects had a higher rate of reoperation and worse patient based outcomes compared to the overall cohort of tibial fracture patients. Further investigation is recommended

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

Purpose. The measurement of functional outcomes in pelvic fracture patients remains difficult for authors. We aimed to test the construct validity, respondent burden, and patient perception of three previously published pelvic outcome questionnaires. Method. Subjects completed three pelvic specific, and three general functional outcome instruments. Time for each pelvic instrument was recorded, as was which score the patient felt best addressed their symptoms. Patients stated the three most significant impacts the pelvic fracture had on their life. Results. We recruited 33 patients, who were a mean of 61 months from surgery (13–115 months). Mobility difficulty (26), emotional stress (20), employment difficulty (15), sleep and anxiety (7), sexual function (4), were the most important consequences of their injuries. All pelvic questionnaires correlated with the physical component summary of the SF-36 (Majeed 0.877, Iowa 0.876, Orlando 0.868). None correlated with the mental component summary. The Iowa and Majeed questionnaires demonstrated ceiling effects, with 24% and 21% having the highest possible scores. Time was 3.6 + 0.4 minutes (Iowa), 7.4 + 0.4 (Orlando) and 2.6 + 0.2 (Majeed). Twelve patients each preferred the Iowa and Orlando, and 9 preferred the Majeed. Conclusion. All three previously published pelvic outcome instruments demonstrated strong construct validity with high correlation the PCS the SF-36, but ceiling effects and respondent burden limit the utility of the current instruments. Mental and emotional outcomes were important consequences of the injuries; however, none of the pelvic questionnaires measure these domains, as they all correlate poorly with the MCS of the SF-36

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

Purpose: We aimed to preliminarily validate a newly developed system, the radiographic union scale for tibial (RUST) fracture healing. We hypothesized that RUST would demonstrate better inter-rater reliability than assessment of the number of cortices bridged and correlate with functional outcomes at least as strongly as surgeon’s assessment of cortical bridging. Method: Three blinded orthopaedic trauma surgeons independently assigned a RUST score and a number of cortices bridged by callus (zero to four) to each set of AP and lateral radiographs at each follow up period. RUST is scored from four (definitely not healed) to 12 (definitely healed) based on the presence or absence of callus and of a visible fracture line at the total of four cortices visible. Results: For 549 sets of reviewed radiographs, inter-rater reliability for RUST scores were found to be substantially higher than for assessment of the number of cortices bridged (intra-class correlation coefficient=0.84; 95% CI, 0.80–0.87 versus kappa = 0.73; 95% CI, 0.64 – 0.81, respectively). Both methods of assessing radiographic healing were strongly correlated with weight-bearing status (r and ρ> 0.50), moderately correlated with patient-reported functional recovery and the SF-36 Physical Functioning component scores (r and ρ> 0.30), and minimally correlated with HUI Mark II scores, return to work, and the SF-36 Role Physical component and Physical Component Summary scores (r and ρ> 0.10). Neither assessment was correlated with patient-reported pain scores. All correlations were similar for RUST and the number of cortices bridged. Conclusion: This study provides preliminary evidence that RUST can be used as a valid and reliable alternative assessment of tibial fracture healing

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

Background. Deciding how to allocate scarce surgical resources is a worldwide issue. These decisions are difficult when considering procedures aimed primarily at improving functional quality of life, such as lower extremity joint replacement (LEJR) surgery, and procedures perceived as life preserving which also have impacts on physical function, such as coronary artery bypass graft (CABG) surgery. Comparing functional outcomes of these two procedures may provide further evidence to guide resource allocation decisions. Methods. We compared patient-reported functional outcomes following CABG and LEJR surgery using standardised, validated outcome metrics. A retrospective review of prospectively collected pre- and post-operative health related quality of life (SF-36) measures were conducted from 105 patients undergoing elective CABG and 105 elective LEJR surgery patients. Patients were matched based on gender and age. Results. Pre-operatively, CABG patients reported statistically superior (p< 0.05) Physical Functioning, Bodily Pain, and Physical Component summary SF-36 scores compared to LEJR patients. However, their pre-operative General Health scores were lower. Surgery resulted in improvements in SF-36 scores for all patients, with statistically significant improvements in Bodily Pain and Physical Component scores occurring in both groups. Interestingly, improvements in 8 out of 10 SF-36 index scores were greater in the LEJR group, with the exception of Vitality and the Mental Component Summary. The pre-operative pattern of statistically better Physical Functioning in the CABG group, and superior General Health scores in the LEJR group remained following surgery. Conclusion. It appears that, despite being matched for age and gender, significant pre-operative general health differences exist between CABG and LEJR patients that persist post-operatively. While surgery results in significant improvements for both groups, CABG patients enjoy greater improvement in General Health scores while LEJR patients benefit from greater improvements in Bodily Pain scores. Further research is underway, examining how these differences reflect disease-specific scores and health care resource utilisation

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.

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

Introduction Hallux valgus (HV) is a common foot deformity with a prevalence of up to 48%. It usually affects females and its radiographic severity is expressed by various angles, such as the HV Angle, the Inter Metatarsal Angle (IMA) and the Distal Metatarsal Articular Angle (DMAA). The aim of our study was to assess the impact that HV has on patients’ quality of life and to correlate each of the above angles to SF-36 sub-scales. Method Twenty-three female patients with a mean age of 48.5 years were included in the study. Diagnosis was established by clinical and standardised radiological examination. Patients were medically fit and the only pathology that could affect their SF-36 score was HV. They all completed in the SF-36 form on their first visit at the clinic. Statistical analysis was performed via SPSS 12.0. Results Mean radiographic angular deformities measured 35, 13, and 17 degrees for HVA, IMA, and DMAA respectively. The HVA and IMA demonstrated significant association (p=0.018) as regarding their severity, indicating that they probably interact during the progression of the deformity. The Physical Component Summary score was significantly lower in our patients than the recommended norms for the same age (p=0.015). HVA significantly affected the General Health (p=0.023), IMA, the Role Physical (0.039), Role Emotional (p=0.056) and Mental Health (p=0.043). The coefficients were all negative indicating a worse health scenario as the deformity increases. Conclusion These results suggest that HV deformity seriously affects peoples’ quality of life. In addition, according to our data, surgical treatment is absolutely indicated and operative correction of the angular deformities would be expected to normalise those patients’ SF-36 score. However, this remains to be proved

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

We report the follow-up of a cohort of 86 patients who underwent total hip replacement (THR) with custom-made stem prosthesis. Fixation mode, cemented (group 1) or uncemented (group 2) is based on the bone quality. Aspects of physical health and changes in mental health are documented using 3 patient-administered questionnaires, pre-operatively and 6 weeks, 3, 6 and 12 months post-operatively. Harris Hip Score (HHS), Hip disability and osteoarthritis outcome score (HOOS) and SF-36, multi-purpose, short-form health survey were used. Globally HHS increases significantly (p< 0.01). In group 1 up to 3 months post-operatively and in group 2 up to 1 year. (p < 0.05). In group 2 HHS is significantly higher 6 months and 1 year postoperatively (p< 0.05). No significant differences in HOOS subscores between subjects of group 1 and 2 for subsequent time points were found. The scores related to Pain and Symptoms increased significantly 6 weeks after THR (p< 0.01). Sports and recreation scores increased significantly up to 3 months after THR (p< 0.01). Activities of daily living, and Quality of Life (QoL) improved up to 6 months after surgery (p< 0.01). No significant difference between the 2 groups in QoL was observed. The physical component summary increased up to 3 months after surgery (p< 0.01). The mental component summary did not change significantly after THR. The difference noted in HHS between group 1 and 2 may be due to the selection of the fixation technique which is often directly related to the patient’s age. The results of the HOOS score confirm the findings of the HHS. Not all patients responded to the questions relative to recreation and sport of the HOOS score. QoL is an important indicator for success as perceived by the patient. In this study a rapid improvement of QoL is observed (3 months) and there is little change at 6 and 12 months

In the litterature patients suffering Mb. Scheuermann (MS) have been reported to experience more back pain and other back related constrains compared to subjects matched for age and sex. We have been unable to find publications on health-related quality of life by SF-12 or SF-36 in MS. The aim of the present study was to compare health-related quality of life status in MS to the background population. Materials and Methods: The present cohorts are derived from The Danish Twin Registry and consist of all Danish twins born from 1931 through 1982. This twin cohort has been shown to very closely resemble the general Danish population. A total of 46,418 twins received and 75% returned a questionnaire of which 34,007(97.3 %) answered the question ‘Have you been diagnosed with Scheuermann’s disease?’ Included in the questionnaire were the standardised questions for The Medical Outcome Study Short Form-12 (SF-12), from which we calculated the SF-12 Physical Component Summary scale (SF-12 PCS) and the SF-12 Mental Component Summary scale (SF-12 MCS) using the SF Health Outcomes Scoring Software. Nine-hundred-and-forty-three reported to have MS and the remaining 33,064 responders were used as controls. Results: The mean(SD) age in the MS group was 43.7(11.9) years compared to 44.4(13.7) in the control group (NS). The overall self-reported prevalence of MS was 2.8% (95% c.i.l. 2.6–3.0), male : female prevalence was 3.6% (95% c.i.l. 3.2–4.1) : 2.1% (95% c.i.l. 1.9–2.3). In the controls male : female prevalence was 45.2% (n=14,953) : 54.8% (n=18,111). Conclusion: The perceived health status from SF-12 PCS in self-reported MS was moderately though highly significantly worse than in controls in a big cohort of Danish twins. There was no difference in SF-12 MCS between the two groups

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

Purpose: Tibial shaft fractures are a common injury. Tibial nailing is the current standard of care for these injuries, yet there is little information regarding patient based outcomes after nailing. We sought to determine the 1 year patient based outcomes and return to activities for patients with tibia fractures in a randomized trial of reamed and unreamed nail insertion. Method: Over a 5 year period 1226 patients with 842 closed and 406 open tibial shaft fractures were enrolled in a randomized trial comparing reamed with unreamed tibial nail insertion in 29 trauma centers and had one year follow-up. The average age was 39±16 years and 74% were male. Patient based outcomes were determined using the validated Short Form-36 (SF-36) Physical Component Summary, the Short Musculoskeletal Functional Assessment (SMFA) Dysfunction Index, and a published return to activity questionnaire. Questionnaires were administered during the initial hospitalization to obtain pre-injury status, and then the same outcome instruments were used at the 2 week, 3 month, 6 month, and one year follow-up. Statistical analysis was performed comparing the groups with p < 0.05 designated as significant. Results: There was no difference in any outcome parameter for any time frame between the reamed and unreamed groups. The 1 year SF-36 PCS (a 100 point scale with a mean of 50 in the general population, higher better) was 42.9±11 for the reamed group and 43.5±11 for unreamed group as compared with 52.5±9 for the reamed group and 53.1±9 for the unreamed group pre-injury. The SMFA Dysfunction Index (100 point scale, higher is worse) at 1 year was 18.2±17 for the reamed group and 17.5±17 for the unreamed group as compared with 7.9±13 for the reamed group and 7.7±13 unreamed group pre-injury. Conclusion: In patients with tibial shaft fractures treated with intramedullary nails, patient based outcomes are not related to reamed or unreamed insertion. Patients sustaining tibial shaft injuries do not return to their pre-injury status based on validated outcomes assessments or return to activity by one year after injury

Purpose: Balloon kyphoplasty (BKP) is a minimally invasive treatment for acute vertebral compression fractures (VCF) that aims both to correct associated vertebral deformity (reduce) and stabilize the fracture by injecting bone cement. We performed the first multicenter randomized trial to assess the effect of BKP. Method: Patients with 1–3 non-traumatic vertebral compression fractures diagnosed within 3 months were randomly assigned to receive either BKP (N=149) or usual nonsurgical care (NSC) (N=151). Measurements of quality of life, back pain and function, days of disability and bed rest were assessed at baseline, 1, 3, 6 and 12 months. Results: The primary outcome measure, the difference between groups in change from baseline scores in the physical component summary of the SF-36 questionnaire, improved 3.5 points (95% CI, 1.6 to 5.4; p=0.0004) more in the BKP group when averaged across 12 months of follow-up. Compared with the NSC group, those assigned to BKP also had greater improvement in quality of life and back function throughout 12 months of follow-up as measured by the EuroQol and Roland-Morris scales; a difference of 0.14 points (95% CI, 0.05 to 0.23; p=0.0023) more and 3.2 points (95% CI, 1.7 to 3.8; p< 0.0001) and reported fewer days of limited activity in the previous 2 weeks due to back pain (2.5 fewer days; 95% CI, 1.2 to 3.8; p=0.0001). New radiographically detected vertebral fractures occurred in 41.8% of subjects in the kyphoplasty and 37.8% in the nonsurgical group (4% difference; 95% CI −7.5 to 15.6; p=0.5). Conclusion: Compared to nonsurgical treatment, balloon kyphoplasty improved multiple measurements of quality of life, back pain and disability that last at least one year after the procedure. No difference is seen between groups in radiographically detected VCF’s (Clinicaltrials.gov number, NCT00211211)

Purpose. The prevalence of focal chondral lesions reported inthe literature during knee arhroscopy can be as high as 63%. Of these, more than half are either grade III or grade IV lesions (Outerbridge). Full thickness cartilage lesions ranging from 2cm2 to 10cm2 are the most challenging to treat. To goal of this study was to evaluate clinical outcomes of pain, function and quality of life, along with radiological outcomes of cartilage repair using microfracture, autologous minced cartilage and polymeric scaffold. Method. A cohort of thirty-eight patients with Outerbridge grade III or IV cartilage injuries larger than 2cm2 in the knee's femoral condyle, trochlea or patella were prospectively folowed since 2008. They were all treated with microfracture, fresh minced autologous cartilage grafting and a polymeric scaffold technique through mini-arthrotomy of the knee. Autografts and scaffolds were secured to subchondral bone using fibrin glue and tran-sosseous resorbable sutures. Patients were evaluated pre and postoperatively using VAS scores for pain, WOMAC and IKDC scores for knee function and SF-36 questionnaire for quality of life. Clinical evaluations were done by physical examination, and imaging was done using X-Rays, MRI and arthro-CT. Results. Mean follow-up time was14.64.6 months. Mean age was 48.39.3 years old. Pre-op lesions averaged 3.51.5 cm2. VAS pain scores were significantly reduced after surgery (7,62 to 2,52.3, p<. 0001). Improvement in knee function using IKDC score improved from 26,717.5 to 55,415.3, p<. 001). In addition, WOMAC total scores showed significant reduction from 55,520.3 to 27,517.6. SF-36 quality of life Physical Component Summary improved from 26,411.4 to 45,812.3, p<. 01; Mental Component Summary improved from 41,916.8 to 49,411.2, p<. 048). Imaging results indicate sustained cartilage thickness from 6 to 18 months. One patient was an early failure due to scaffold loosening, and two patients had no clinical improvement and no significant cartilage regeneration on MRI and Arthro-CT imaging at 6 months post-op. Conclusion. The combination of microfractures, fresh minced autologous cartilage grafting and polymeric scaffold fixation seems to be an effective treatment option for post-traumatic and focal cartilage lesions of the knee in the short term. A longer-term follow-up to evaluate the sustainability of these results is ongoing. Shortcomings of this study are its short term, the lack of second look arthroscopies and cartilage biopsies to evaluate cartilage microstructure, and the absence of a gold standard treatment for full-thickness cartilage lesions larger than 2cm2 that could be used as a control

Osteoarthritis (OA) is one of the most common causes of knee pain in the aging population and presents with higher odds with increased BMI. Total knee arthroplasty (TKA) has become the standard of care for the treatment of OA. Over “719,000 TKA's were performed in 2010 in the USA alone, with dramatic economic burden- costing 16,000 USD per TKA” (CDC 2012). Over the past two decades, this cost was compounded by the unknown increasing rate of primary TKA and cannot be explained by the expanding population or worldwide obesity epidemic. These facts raise two key questions: are patients' quality of life expectations higher and driving the TKA rate up, or have surgeons changed their indications and started to operate on less disabled people? Our study aimed to determine the average functional profile for patients undergoing TKA using patient reported Outcome Measure (SF-36), to document if preoperative SF-36 scores have changed over the past two decades, and lastly to asses if patient pre-operative SF-36 scores are lower in in the USA vs the rest of the world. A literature search of Medline, Embase and Cochrane databases was performed extracting data from publishing year 1966 to 2016 with a search date of Dec 12, 2016. Two independent reviewers revised the abstracts and excluded articles with: no TKA, revision TKA, no pre-op SF-36, no SF-36 reported, incomplete scores to calculate SF-36, duplicates, review article, meta-analysis, letter to the editor, conference proceeding or abstract, disagreements were resolved with a third reviewer. All languages were included to maximize the catchment of data. All remaining articles were independently read and excluded if they did not provide data required for our study. Included articles were analyzed for data including: for year of patient enrollment, location (USA vs. non-USA), pre-operative SF-36 mental (MCS) and physical (PCS) component summary, level of evidence. Recorded data was compared post completion to assess inter-observer accuracy as per PRISMA guidelines for meta-analysis. After applying all the exclusion criteria on 923 selected abstracts, a total of 136 articles of which 30 were randomized control trials, were completely reviewed and included in our study. A total of 56,713 patients' physical component scores were analyzed and revealed an overall pre-operative SF-36 physical component score 31.93. When stratifying the data, it was revealed that patients operated in the USA had an average score of 32.3 whereas Non-US countries were 31.7, with no statistical significance. No statistical difference between SF36 scores was seen over time amongst studies of all nations. Based on the results of this study, we have shown that orthopaedic surgeons are performing TKA universally at the same pre-operative scores, independent of country of origin or year of surgery. The indications thus have remained consistent for two decades regardless of the advances in technology. Functional profiles of patients appear similar among US and Non-US countries. Further, we infer that based on pre-operative SF-36 PCS scores, the optimal time to undergo a TKA is when PCS is 31.9 +/−3

Purpose: To report the clinical and radiographic prospective results of a consecutive series of patient with a minimum two year follow-up with the Charite Total Disc Arthroplasty (TDA). Method: Between 2001 and 2005, sixty patients underwent a Charite TDA (Depuy Spine, Raynham, MA) at either L4-5 or L5-S1. The primary indication for surgery was discogenic low back pain confirmed by provocative discography. Clinical assessment was carried out preoperatively and postoperatively at 3, 6, 12 months, and once a year thereafter using the Oswestry Disability Index (ODI), Visual Analogue Scale (VAS) for back and leg pain, and SF-36. Radiographic analysis included: angle of sagittal rotation, translation of the rostral vertebra onto the caudal vertebra, anterior vertical motion (AVM), middle vertical motion (MVM), posterior vertical motion (PVM), pre- and post-operative lumbar lordosis, disc height and subsidence of the TDA. The radiographic measurements were performed using the GE Medical Systems Centricity PACS Software Version 1.0. Results: There were 36 female and 24 male patients with a mean age of 39 (range 21–59). The mean duration of low back pain was 70 months. Twenty-five percent claimed work compensation status. The mean postoperative hospital stay was 4.8 days. A statistical significant improvement was demonstrated between the mean pre-operative ODI (50) and all post-operative intervals (p< 0.0001) which had declined to 27.7 by one year. Similarly, pre-operative VAS back pain (8.0), leg pain (6.1), SF-36 physical component summary score (33.5) and mental component summary score (41.8) remained improved (p< 0.0001) by three months (4.1, 3.1, 51.7, 62.0 respectively). One patient with an L5-S1 TDA has since undergone a posterolateral instrumented fusion. The mean pre- and post-operative lumbar lordosis was 34.58 and 53.48 respectively. The mean saggital rotation was 6.5 degrees at 5 year follow-up, while the mean translation was 0.83 mm. The mean AVM, MVM and PVM were 0.59 mm, −3.96 mm and 3.69 mm respectively at 5 year follow-up. Conclusion: This study demonstrates satisfactory clinical results in carefully selected patients. The radiographic assessment confirmed preservation of movement at the replaced disc during flexion and extension of the lumbar spine

Introduction: Minimally invasive total hip arthroplasty has evoked substantial controversy with regard to whether it provides superior outcomes compared with conventional total hip arthroplasty. The objective of this study was to compare the results of a minimal invasive direct anterior approach (MIDA) with those of a conventional lateral transgluteal approach (CLT). Methods: 120 patients (120 hips) admitted for unilateral total hip arthroplasty were randomized to undergo surgery via minimal invasive direct anterior or conventional lateral transgluteal approach. Patients with a body mass index of more than 35, previous hip surgery, preoperative neurological deficits and with an age of more than 80 years were excluded. Two surgeons performed all procedures. To estimate muscle damage serum creatinkinase was assessed. Blood loss was calculated according to Rosencher by comparing preoperative to postoperative hematocrit. Postoperative pain and the ability to perform the activities of daily living were recorded in a dairy via modified WOMAC first on a daily basis, then on each second day and finally once a week for a total of 12 weeks. WOMAC questionnaire and SF-36 were administered at 6 weeks and 3 months follow-up. Results: The groups were similar demographically. Patients in MIDA group had significantly less total blood loss (p = 0.006), postoperative blood levels of creatinine kinase were significantly lower (p = 0.001). Operative time was similar in both groups, we found no difference in component placement. Physical component summary of SF-36 at 12 weeks follow-up showed a significant benefit for the MIDA group. Averaged modified WOMAC scores and their pain and function subscores demonstrated a clear advantage on every recorded day during the first 12 weeks for MIDA. Median WOMAC sum score and respective pain as well as function subscores were better in the MIDA group at 6 and 12 weeks follow up. Conclusions: A minimally invasive direct anterior approach is superior to a conventional lateral transgluteal approach with regard to blood loss and muscle trauma, resulting in better health related quality of life in the first three months after operation

Introduction: Clubfoot – Congenital talipes equinovarus (CTEV) – is one of the most common congenital conditions requiring orthopaedic surgery. However little is known about the impact on health-related quality of life in these patients. A score on physical- and mental-health is used for this purpose. The aim of the present study was to compare health-related quality of life in CTEV to a background population. Materials and Methods: The Odense based Danish Twin Registry (DTR) is unique as it contains data on all 73,000 twin pairs born in Denmark over the last 130 years. All 46,418 twins born from 1931 through 1982 received an Omnibus questionnaire in the spring of 2002. The incidence of CTEV was self-reported. Included in the questionnaire were questions for The Medical Outcome Study Short Form-12 (SF-12). We calculated SF-12 Physical Component Summary scale (SF-12 PCS) and SF-12 Mental Component Summary scale (SF-12 MCS) using the SF Health Outcomes Scoring Software. 80 reported to have CTEV and the remaining 29,516 were used as controls. Results: 46,418 twins received and 34,944 (75%) returned the questionnaire. 34,485 (99% of the responders) answered the question ‘Were you born with club-foot?’ The sex distribution in these was 15,731 (46%) males and 18,754 (54%) females. The self-reported prevalence of CTEV was 0.0027 (95% confidence interval 0.0022–0.0034). 80 reported to have CTEV and the remaining 29,516 were used as controls. In the CTEV group SF-12 PCSmean was 50.18 (SD 11.19) vs 53.09 (SD 8.11) in the controls. p< 0.0007. In the CTEV group SF-12 MCSmean was 50.58 (SD 10.52) vs 51.78 (SD 8.47) in the controls. NS. Conclusion: The impact of congenital clubfoot on health-related quality of life was significant only on the physical scale. The clubfoot patients scoring lower than the controls. There was no difference in the mental scale between the two groups

Purpose: The treatment of large osteochondral lesions of the talus (OLT) remains a challenge. Fresh Osteo-chondral Allograft is a method that has been used for the treatment of larger lesions, with the advantage of transplanting living cartilage that is biologically attached to the subchondral bone. The purpose of this clinical series is to prospectively review the clinical and radiographic outcomes of patients that have undergone a Fresh Osteochondral Allograft. Method: Between January 2003 and January 2007, 17 feet in 8 male and 8 female patients at a mean age of 35.8 (15–53) years underwent fresh osteochondral talar allo-grafting by a single surgeon. Data was prospectively collected, including preoperative and postoperative AOFAS, AOS, AAOS foot & ankle worksheets and SF-36 scores. Statistical analysis consisted of one tailed student T-test with alpha set a 5%. All patients were followed up clinically and radiographically by x-ray and CT scan. Results: Average follow up was 3.2 (0.9–6.2) years. All scoring systems showed significant improvement postoperatively, except for AAOS shoe comfort scores, and the Mental Component Summary of the SF-36 questionnaire. The AOFAS score improved significantly (p=0.0001) from a mean score of 53.4 (30–71) to 86.3 (72–96). AOS pain scores improved significantly (p=0.0053) from a mean score of 45.4 (8.7–72.2) to 24.1 (4.2–58.9). AOS disability score improved significantly (p=0.0013) from a mean of 53.8 (7.8–77.3) to 25.9 (6.6 – 62.5). The AAOS foot & ankle core scale (standardized mean) improved significantly (p=0.0015) from a mean of 52.3 (21–81) to 80.1 (56–99). The AAOS foot & ankle core scale (normative score) improved significantly (p=0.0016) from a mean of 16.9 (−9 to 40) to 39.5 (20–55). The SF-36 Physical Component Summary improved significantly from a mean of 34.9 (24.2–43.8) to 47.3 (36.6–59.8). There was successful osseous graft incorporation in 16/17 feet (94%) verified on CT scan. Of the 16 grafts which had successfully incorporated, radiographic follow up showed 4/16 feet (25%) had signs of progressive OA and 3/16 feet (19%) had developed new osteolysis around the graft. Conclusion: Although patients’ functional outcome can be substantially improved with the use of fresh osteochondral allografts the early radiographic findings are of concern with 43% demonstrating progression of arthritis or osteolysis of the graft during the process of graft incorporation

Purpose: To report the clinical and radiographic prospective results of a consecutive series of patient with a minimum two year follow-up with the Charite Total Disc Arthroplasty (TDA). Methods: Between 2001 and 2005 sixty patients underwent a Charite TDA (Depuy Spine, Raynham, MA) at either L4–5 or L5-S1. The primary indication for surgery was discogenic low back pain confirmed by provocative discography. Clinical assessment was carried out preoperatively and postoperatively at 3, 6, 12 months, and once a year thereafter using the Oswestry Disability Index (ODI), Visual Analogue Scale (VAS) for back and leg pain, and SF-36. Radiographic analysis included: angle of sagittal rotation, translation of the rostral vertebra onto the caudal vertebra, anterior vertical motion (AVM), middle vertical motion (MVM), posterior vertical motion (PVM), pre- and post-operative lumbar lordosis, disc height and subsidence of the TDA. The radiographic measurements were performed using the GE Medical Systems Centricity PACS Software Version 1.0. Results: There were 36 female and 24 male patients with a mean age of 39 (range 21–59). The mean duration of low back pain was 70 months. Twenty-five percent claimed work compensation status. The mean post-operative hospital stay was 4.8 days. A statistical significant improvement was demonstrated between the mean pre-operative ODI (50) and all post-operative intervals (p< 0.0001) which had declined to 27.7 by one year. Similarly, pre-operative VAS back pain (8.0), leg pain (6.1), SF-36 physical component summary score (33.5) and mental component summary score (41.8) remained improved (p< 0.0001) by three months (4.1, 3.1, 51.7, 62.0 respectively). The mean pre and post-operative lumbar lordosis was 34.58 and 53.48 respectively. The mean sagittal rotation was 6.5 degrees at 5 year follow-up, while the mean translation was 0.83 mm. The mean AVM, MVM and PVM were 0.59 mm, −3.96 mm and 3.69 mm respectively at 5 year follow-up. Conclusion: This study demonstrates satisfactory clinical results in carefully selected patients. The radiographic assessment confirmed preservation of movement at the replaced disc during flexion and extension of the lumbar spine. Interest Statement: No financial benefits or funding has been received for the completion of this study

Purpose. The purpose of this study was to compare the outcomes and complications of normal weight, class one obese (BMI=30-34.9 kg/m2) and superobese (BMI≥50 kg/m2) primary total knee replacement (TKR) patients. Method. Between January 1995 and December 2005, 4104 primary TKR were performed in our centre. Patients were stratified for their obesity level according the World Health Organisation (WHO) and current surgical literature classification. Sixty-seven superobese patients (group one) were identified. They were matched with normal weight (group two) and class one obese (group three) primary TKR patients for sex, age, side, preoperative diagnosis, implants used, time since surgery and preoperative SF-12 mental component summary score (MCS). Patient clinical outcomes (WOMAC, SF-12 and Knee Society scores), radiographs, complications, readmissions, and revisions rates were compared for normal BMI, class one obese and superobese patients. Results. The mean BMI of our primary TKR patients was 32,6. Using the WHO BMI classification, 0.3% were underweight, 10.4% normal weight, 30.1 % overweight, 31.0 % class 1 obesity, 16.5 % class 2 obesity, 9.8 % class 3 obesity and 1.9 % superobese. Superobese population (n=67) was 61.59.2 yo, with sex ratio at 5.1 (F=56;M=11), preoperative SF-12 MCS at 52.610.6. Their preoperative diagnosis was osteoarthritis (n=62) or inflammatory arthritis (n=5). All groups were equal (n=67) and were similar for these characteristics. Mean clinical and radiographic follow-up was 7.33.2 yrs. Superobese patients presented lower preoperative SF-12 physical component summary (PCS; gp 1=26.05.6; gp 2=29.68.4; gp 3=30.57.8; p<0.05), Knee Society score (gp 1=73.626.4; gp 2=84.926.5; gp 3=88.517.4; p<0.05) and WOMAC scores (gp 1=35.814.5; gp 2=44.116.7; gp 3=41.315.7; p<0.05). However the three groups presented a similar improvement of the SF-12 PCS (gp1=10.512.0; gp2= 6.810.9; gp3=6.812.1; p= 0.22) and Knee Society score (gp1=81.930.8; gp 2= 74.220.9; gp 3=78.729.9; p= 0.21). The superobese patients group had a significantly longer hospital stay, higher complication rate, and were more frequently re-admitted to hospital and submitted to revision surgery. Conclusion. Superobese patients can enjoy comparable clinical outcomes when compared to patients with lower BMIs, but do run increased risks in terms of a complication and a greater hospital re-admission rate

Objectives: (i) To compare and correlate outcome in Sanders Type 2 Os Calcis fractures using two disease-specific scores (Kerr-Atkin score & American Orthopaedic Foot and Ankle society score) and a general quality of life score (short form 36 health status questionnaire). (ii) To compare results of operative with non operative treatment, in this group of patients. Design: Retrospective study using a combination of case notes, plain x-rays and CT scan films review along with current clinical assessment. Patients: 30 patients with 32 fractures of Os Calcis (Sanders type 2) were identified. These patients were treated during 1994–1997 with mean follow up of 40 months. Intervention: 16 patients were treated by open reduction and internal fixation using a lateral approach. The remaining 14 patients were managed non operatively. Treatment modality was decided by consultant preference. Outcome measurements: Kerr-Atkin score, AOFAS score, SF36. Results: We found an extremely significant correlation (p,.001, Spearman) between the two disease specific scores. AOFAS score showed a stronger correlation with physical component summary score (PCS) of the SF36 than the Kerr-Atkin score. The age of the patient had little impact on the Kerr-Atkins score but a large effect on PCS. Conversely the pre-op Bohlers angle, a measure of fracture severity, had a large effect on the Kerr-Atkins score but little impact on the PCS. The AOFAS was responsive to both these predictors: 41% of the variance in AOFAS score was explained by Bohlers angle and the age of the patient. We did not find any significant difference in outcome between operative and non-operatively treated patients. Conclusion: The AOFAS score was found superior in assessment of outcome for Sanders type 2 fractures, though the Kerr-Atkin score also performed well. This study does not demonstrate any significant advantage of operative treatment in Sanders type 2 fractures of the Os Calcis

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

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

The use of metal on polyethylene articulations was a key development in establishing total hip arthroplasty as a successful and reproducible treatment for end stage osteoarthritis. In order to ensure implant durability in relatively younger populations, there is a need for alternative, wear resistant bearing surfaces. 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 early clinical outcomes following primary total hip arthroplasty with Oxinium versus Cobalt Chrome femoral heads. One-hundred primary THA procedures were prospectively performed in 100 patients. There were 52 males and 48 females. Using a process of sealed envelope randomization, patients were divided into 2 groups. Group 1 consisted of fifty patients, each receiving primary THA implants with an Oxinium femoral head (OX). The mean age of each patient was 51 years (SD 10.8, Range 22–74) with 26 males and 24 females. Group 2 also consisted of 50 patients. Within this group again each patient received primary THA implants however with a cobalt-chrome femoral head (CC). Demographics were similar with mean age 51 years (SD 11.0, Range 19–76) and again 26 males and 24 females. 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

Aims

The aim of this study was to investigate whether the type of cervical disc herniation influences the severity of symptoms at the time of presentation, and the outcome after surgical treatment.

PURPOSE: Patients who sustain fall-related distal forearm fractures are at risk to sustain new fractures later in life. Risk factors for falls such as low physical activity, impaired gait and neuromuscular function, and comorbidity are well known, as well as risk factors for fractures such as female gender, old age, low body mass index (BMI) and low mobility. Fracture prevention is often directed toward bone mass density treatment, but there is evidence that high level of physical activity reduces falls and therefore also reduces fractures. Health related quality of life (HRQoL) has become an important additional measure. The aims of this study were to evaluate the HRQoL, reported with EQ-5D and SF-12, in women who had sustained fall-related distal forearm fracture one year earlier and compare with Swedish normative data, and to physical performance and self-reported comorbidity. PARTICIPANTS: Sixty women with a fall-related distal forearm fracture were invited to examine health-related quality of life and physical performance at a mean time of 13 months after they had sustained their fracture (S.D. 1.6, range 10–17). The inclusion criteria were that they should be able to perform the physical tests and to understand verbal and written Swedish. Forty three women (72%), mean age 68 (SD 8.4, range 50–84), agreed to participate. METHODS: The women filled in two generic HRQoL-questionnaires; EQ-5D and SF-12. They self-rated their physical activity and reported ailments, which were regularly examined by a doctor, and intake of prescribed medication. They reported problems or difficulties from the locomotor system and depressive symptoms during the three last months. All women underwent physical performance tests; handgrip strength, one leg standing (OLS) and walking speed. Fisher’s exact test, Mann Whitney U test and Spearman’s rank correlation coefficient were used in the statistical analyses. RESULTS: In the younger women (age 50–59) the HRQoL was lower compared to Swedish normative data. The EQ-5D index and VAS scores correlated moderately to the physical component summary (PCS-12) of the SF-12 (rs=0.73 and rs=0.69, respectively). The correlation to the mental component summary (MCS-12) of the SF-12 was lower (rs=0.32 and rs=0.22, respectively). Women who reported comorbidity and low physical activity scored lower in the corresponding items of health in both questionnaires. CONCLUSIONS: Low results in HRQoL questionnaires in apparently healthy older women with fall-related distal forearm fracture may indicate underlying comorbidity, not captured by physical performance tests. We suggest that HRQoL questionnaires should be used in additional to physical outcome measures for this patient group. The use of HRQoL questionnaires to find patients for preventive measures of falls and fractures should be further explored

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

Aims

The aim of this study was to explore the functional results in a fitter subgroup of participants in the Hip Fracture Evaluation with Alternatives of Total Hip Arthroplasty versus Hemiarthroplasty (HEALTH) trial to determine whether there was an advantage of total hip arthroplasty (THA) versus hemiarthroplasty (HA) in this population.

Aims

The purpose of this study was to assess the success rate and functional outcomes of bone grafting for periprosthetic bone cysts following total ankle arthroplasty (TAA). Additionally, we evaluated the rate of graft incorporation and identified associated predisposing factors using CT scan.

Aims

This prospective study reports longitudinal, within-patient, patient-reported outcome measures (PROMs) over a 15-year period following cemented single radius total knee arthroplasty (TKA). Secondary aims included reporting PROMs trajectory, 15-year implant survival, and patient attrition from follow-up.

Aims

Lateral femoral cutaneous nerve (LFCN) injury is a complication after periacetabular osteo-tomy (PAO) using an anterior approach, which might adversely affect the outcome. However, no prospective study has assessed the incidence and severity of this injury and its effect on the clinical outcomes over a period of time for longer than one year after PAO. The aim of this study was to assess the incidence and severity of the symptoms of LFCN injury for ≥ three years after PAO and report its effect on clinical outcomes.

Aims

The primary outcome was investigating differences in wear, as measured by femoral head penetration, between cross-linked vitamin E-diffused polyethylene (vE-PE) and cross-linked polyethylene (XLPE) acetabular component liners and between 32 and 36 mm head sizes at the ten-year follow-up. Secondary outcomes included acetabular component migration and patient-reported outcome measures (PROMs) such as the EuroQol five-dimension questionnaire, 36-Item Short-Form Health Survey, Harris Hip Score, and University of California, Los Angeles Activity Scale (UCLA).

Introduction: The role of spinal fusion in patients suffering degenerative spine disease may be scrutinized more as costs of surgical treatment rise. Health-related quality of life (HRQL) measurement instruments enable outcome comparisons following treatment of different medical conditions. Rampersaud et al (1) recently presented the results of a comparative study of HRQL outcomes after surgery for lumbar spinal stenosis and hip and knee total joint arthroplasty. The latter are now accepted benchmarks for improvement in patient health. Methods: A retrospective, observational cohort study was undertaken of 12-item Short Form Health Survey (SF-12) outcome data of 105 consecutive patients of two surgeons (1st and 2nd authors) who underwent single level Posterior Lumbar Interbody Fusion (PLIF) for lumbar spinal stenosis associated with degenerative spondylolisthesis. Minimum 12-month (F/U) data was available for 98 patients (93%). Comparison was made with published SF-12 results of hip and knee total joint arthroplasty (THR and TKR) and with age-related Australian population norms. Analyses were performed using XLSTAT version 7.5.3. Non-parametric statistics were used for assessment of skewed continuous variables. Overlappng 95%CIs were interpreted as indicating lack of significant difference in outcomes between patient and population groups. Results: Median follow-up was 24months (range: 12–60months). Median age was 65 (Interquartile range: 59–75) years. Male:female ratio 2.8:1. Mean (95%CI) pre-op Physical Component Summary score (PCS) was 28.1 (26.6–29.5). This increased at last F/U to 39.3 (36.9–41.7, P< 0.0001). Mean Mental Component Summary score (MCS) was 47.8 (45.5–50.1) pre-op and 52.3 (50.2–54.5) at last F/U (P=< 0.0001). While there was no difference in patient demographics, a significant difference existed in the pre-op SF-12 scores between the patients of the two surgeons (mean PCS: 24.9 (22.7–27.0) vs. 29.6 (27.8–31.5) and MCS: 44.0 (39.3–48.6) vs. 49.5 (46.8–52.1)). No significant difference was found in the improvements in mean SF-12 scores between these two patient groups (PCS: 12.3 (7.6–17.1) vs. 10.8 (8.3–13.3) and MCS: 6.3 (1.8–10.8) vs. 3.0 (0.3–5.6)) or in the SF-12 scores at 12-months (PCS: 37.2 (32.8–41.6) vs. 40.2 (37.2–43.2) and MCS: 52 (48.3–55.7) vs. 52.3 (50.1–54.4)). No significant difference was found between post-op PCS of the less disabled patient group or MCS scores of either group and published SF-12 age-matched population norms (65–74 years: mean PCS of 44.4 (42.7–46.1) and MCS of 53.8 (52.7–55.0)). Three published series (869 patients) were located providing SF-12 data for TKR surgery. Weighted mean age was 69 years and pre-op PCS was 30 (range:27–34). 12-month improvement in PCS was 7.0 (range:7–8.5). For THR, one paper (147 patients from 3 hospitals) containing SF-12 data was found. Mean age was 68 years (range:36–89). Mean pre-op PCS and MCS of 30.5 and 41.4, increased to 45.6 and 49.7 at one year. Discussion: The current study shows that spinal fusion can return patients’ HRQL to that of age-matched population norms and yield outcomes comparable to those of total hip and knee arthroplasty. Strict comparison with the arthroplasty literature was problematic however owing to variations in the methodology of their data presentation. Prospective collaboration with surgical colleagues in other disciplines is required

Background context: Stable thoracolumbar spinal fracture is a common injury, yet there remains a relative lack of evidence that would allow reliable prediction of outcome. Variation in outcome in stable thoracolumbar spine fracture without neurological deficit could not be explained by the assessment made from x-rays and CT imaging alone, which measures mainly the bony injury severity. So far, no good classification system has been developed to assess the severity of soft tissue injury (disc). Objectives: To measure short-term outcome of stable thoracolumbar fracture and analyse aspects of injury severity for their ability to predict outcome. To develop a new disc injury severity grading system in thoracolumbar spine fractures. Study design: Prospective observational. Patient sample: 44 patients with stable fractures between T11 and L5 vertebra with no neurological deficit and treated conservatively were selected. Methods: All had plain x-rays, CT and MRI scans post-injury and at one year post-injury (except CT). Bony injury severity was scored on a seven-point ordinal scale based on (a) communication, (b) apposition and (c) kyphosis. Disc injury severity was scored by the newly developed six-point ordinal scale (none to severe) based on the following variables: (a) Herniation of the disc, (b) Indentation of the end plate, (c) Change in height and (d) Change in signal. Outcome was assessed at one to two years from injury. The following outcome measures were collected: (A) Five domains of pain symptoms – intensity, duration, bothersome, interference and satisfaction. (B) Five domains of function – Physical Component Summary (PSC) measure, Mental Component Summary (MSC) measure, Oswestry disability score, return to pre-injury level of overall activities and return to employment. Non-parametric correlation coefficients were calculated between outcome variables and other variables to look for the predictors of outcome. Stepwise linear regression analysis was performed to compare the predictive values and to look at what proportion of outcome is predicted by different predictors. Results: According to AO classification, the fractures were A1, A2, A3 and B1. The Spearman correlation coefficients between outcome and injury severity were consistently higher with disc injury severity than bony. For the outcome of pain intensity, the correlation coefficients for disc and bone injury severity respectively were:.63 (p < .0001) and.28 (NS-not significant). Similarly for SF36 PSC were: .41 (p < .01) and.25 (NS). The predictive value of pain at F < .01 was 29% for disc injury severity and all other variable were not significant and excluded. At F < .05, the predictive value of disc injury severity (29%) increased further by 9%, 8% and 6% by addition of variable “Patient’s pre-injury SF36 MSC”, “Legal and Compensation issues pending” and “Physical demand of job” respectively. The predictive value of function at F < .01 was 16% for disc injury severity and it increased to 31% by the addition of “physical demand of the job” variable. At F < 0.05 the predictive value further increased by 5% by addition of variable “Legal and Compensation issues pending”. All other variables were not significant. Conclusions: A new grading system of disc injury severity was developed and it showed good predictive value for pain and functional outcome. Disc injury severity has a better predictive value for short term outcome than bony injury severity in stable thoracolumbar fractures. In the spectrum of injuries studies, the AO classification and the degree of kyphosis provided no prediction of outcome

This edition of the Cochrane Corner looks at the three reviews that were published in the second half of 2023: surgical versus non-surgical interventions for displaced intra-articular calcaneal fractures; cryotherapy following total knee arthroplasty; and physical activity and education about physical activity for chronic musculoskeletal pain in children and adolescents.

Aims

Instability is a common cause of failure after total hip arthroplasty. A novel reverse total hip has been developed, with a femoral cup and acetabular ball, creating enhanced mechanical stability. The purpose of this study was to assess the implant fixation using radiostereometric analysis (RSA), and the clinical safety and efficacy of this novel design.

Aims

We compared decompression alone to decompression with fusion surgery for lumbar spinal stenosis, with or without degenerative spondylolisthesis (DS). The aim was to evaluate if five-year outcomes differed between the groups. The two-year results from the same trial revealed no differences.

Aims

Postoperative complication rates remain relatively high after adult spinal deformity (ASD) surgery. The extent to which modifiable patient-related factors influence complication rates in patients with ASD has not been effectively evaluated.

The aim of this study was to determine the effectiveness of home-based prehabilitation on pre- and postoperative outcomes in participants awaiting total knee (TKA) and hip arthroplasty (THA).

Aims

Revision rates for ankle arthroplasties are higher than hip or knee arthroplasties. When a total ankle arthroplasty (TAA) fails, it can either undergo revision to another ankle replacement, revision of the TAA to ankle arthrodesis (fusion), or amputation. Currently there is a paucity of literature on the outcomes of these revisions. The aim of this meta-analysis is to assess the outcomes of revision TAA with respect to surgery type, functional outcomes, and reoperations.

Aims

Our objective was to conduct a systematic review and meta-analysis, to establish whether differences arise in clinical outcomes between autologous and synthetic bone grafts in the operative management of tibial plateau fractures.

Aims

Injury to the lateral femoral cutaneous nerve (LFCN) is one of the known complications after periacetabular osteotomy (PAO) performed using the anterior approach, reported to occur in between 1.5% and 65% of cases. In this study, we performed a prospective study on the incidence of LFCN injury as well as its clinical outcomes based on the Harris Hip Score (HHS), Short-Form 36 Health Survey (SF-36), and Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire (JHEQ).

Aims

To report early (two-year) postoperative findings from a randomized controlled trial (RCT) investigating disease-specific quality of life (QOL), clinical, patient-reported, and radiological outcomes in patients undergoing a total shoulder arthroplasty (TSA) with a second-generation uncemented trabecular metal (TM) glenoid versus a cemented polyethylene glenoid (POLY) component.

Aims

Preoperative talar valgus deformity ≥ 15° is considered a contraindication for total ankle arthroplasty (TAA). We compared operative procedures and clinical outcomes of TAA in patients with talar valgus deformity ≥ 15° and < 15°.

Aims

Chronic low back pain due to degenerative disc disease is sometimes treated with fusion. We compared the outcome of three different fusion techniques in the Swedish Spine Register: noninstrumented posterolateral fusion (PLF), instrumented posterolateral fusion (IPLF), and interbody fusion (IBF).

Aims

The primary aim of this study was to assess whether pain in the contralateral knee had a clinically significant influence on the outcome of total knee arthroplasty (TKA) according to the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score. Secondary aims were to: describe the prevalence of contralateral knee pain; identify if it clinically improves after TKA; and assess whether contralateral knee pain independently influences patient satisfaction with their TKA.

Aims

The primary aim of this study was to establish the cost-effectiveness of the early fixation of displaced midshaft clavicle fractures.

Aims

This study of patients with osteoarthritis (OA) of the hip aimed to: 1) characterize the contribution of the hip, spinopelvic complex, and lumbar spine when moving from the standing to the sitting position; 2) assess whether abnormal spinopelvic mobility is associated with worse symptoms; and 3) identify whether spinopelvic mobility can be predicted from static anatomical radiological parameters.

Aims

The number of rotator cuff repairs that are undertaken is increasing. Reverse shoulder arthroplasty (RSA) is the procedure of choice for patients with rotator cuff arthropathy. We sought to determine whether patients who underwent rotator cuff repair and subsequent RSA had different outcomes compared with a matched control group who underwent RSA without a previous rotator cuff repair.

Aims

The purpose of this study was to determine the functional outcome and implant survivorship of mobile-bearing total ankle arthroplasty (TAA) performed by a single surgeon.

Aims

The purpose of the present study was to compare patient-specific instrumentation (PSI) and conventional surgical instrumentation (CSI) for total knee arthroplasty (TKA) in terms of early implant migration, alignment, surgical resources, patient outcomes, and costs.

Aims

Robotic-assisted unicompartmental knee arthroplasty (UKA) promises accurate implant placement with the potential of improved survival and functional outcomes. The aim of this study was to present the current evidence for robotic-assisted UKA and describe the outcome in terms of implant positioning, range of movement (ROM), function and survival, and the types of robot and implants that are currently used.

Aims

The aim of this study was to assess the effect of multimorbidity on improvements in health-related quality of life (HRQoL) following total hip arthroplasty (THA) and total knee arthroplasty (TKA).

Aims

The primary aim of this study was to compare the knee-specific functional outcome of patellofemoral arthroplasty with total knee arthroplasty (TKA) in the management of patients with patellofemoral osteoarthritis.

Aims

We performed a meta-analysis investigating the association between preoperative psychological distress and postoperative pain and function after total knee arthroplasty (TKA).

Aims

The aims of this study were to evaluate the abductor function in moderate and severe slipped capital femoral epiphysis (SCFE), comparing the results of a corrective osteotomy at the base of the femoral neck and osteoplasty with 1) in situ epiphysiodesis for mild SCFE, 2) contralateral unaffected hips, and 3) hips from healthy individuals.

Aims

The primary aim of this study was to assess whether patient satisfaction one year after total knee arthroplasty (TKA) changed with longer follow-up. The secondary aims were to identify predictors of satisfaction at one year, persistence of patient dissatisfaction, and late onset dissatisfaction in patients that were originally satisfied at one year.

Pain catastrophising is an adverse coping mechanism, involving an exaggerated response to anticipated or actual pain.

The purpose of this study was to investigate the influence of pain ‘catastrophising’, as measured using the pain catastrophising scale (PCS), on treatment outcomes after surgery for lumbar spinal stenosis (LSS).

A total of 138 patients (47 men and 91 women, mean age 65.9; 45 to 78) were assigned to low (PCS score < 25, n = 68) and high (PCS score ≥ 25, n = 70) PCS groups. The primary outcome measure was the Oswestry Disability Index (ODI) 12 months after surgery. Secondary outcome measures included the ODI and visual analogue scale (VAS) for back and leg pain, which were recorded at each assessment conducted during the 12-month follow-up period

The overall changes in the ODI and VAS for back and leg pain over a 12-month period were significantly different between the groups (ODI, p < 0.001; VAS for back pain, p < 0.001; VAS for leg pain, p = 0.040). The ODI and VAS for back and leg pain significantly decreased over time after surgery in both groups (p < 0.001 for all three variables). The patterns of change in the ODI and VAS for back pain during the follow-up period significantly differed between the two groups, suggesting that the PCS group is a potential treatment moderator. However, there was no difference in the ODI and VAS for back and leg pain between the low and high PCS groups 12 months after surgery.

In terms of minimum clinically important differences in ODI scores (12.8), 22 patients (40.7%) had an unsatisfactory surgical outcome in the low PCS group and 16 (32.6%) in the high PCS group. There was no statistically significant difference between the two groups (p = 0.539).

Pre-operative catastrophising did not always result in a poor outcome 12 months after surgery, which indicates that this could moderate the efficacy of surgery for LSS.
