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

Purpose of Study and Background. Population ageing will facilitate an increase in health problems common in older adults, such as musculoskeletal conditions. Musculoskeletal conditions are the fourth largest contributor to disease burden in older adults; affecting quality of life, physical activity, mental wellbeing and independence. Therefore primary care health services must provide appropriate and efficacious management and treatment. However there are a number of complexities specific to older adults that are essential to address. Methods and Results. In order to identify these complexities, a review of the background literature was undertaken in addition to a Patient and Public Involvement and Engagement (PPIE) session. The PPIE group consisted of eight older adults who experience chronic musculoskeletal pain. This session was used to discuss and explore what factors are important to consider in GP consultations for musculoskeletal pain for older adults, in addition to those identified through background literature. A number of factors were highlighted through these methods, including the difference in mood and aspirations for older adults; taking a holistic approach; the impact of comorbidities; whether the GP is listening and ‘on the same wavelength’, and older adults' expectations regarding their pain and the consultation. Conclusion. Management of musculoskeletal pain for older adults in GP consultations is complex due to a range of factors, reinforcing the importance of taking a holistic approach. The impact of these factors upon the experience and outcomes of GP consultations will be further explored through in depth interviews with older adults with musculoskeletal pain.

Aims

Understanding of open fracture management is skewed due to reliance on small-number lower limb, specialist unit reports and large, unfocused registry data collections. To address this, we carried out the Open Fracture Patient Evaluation Nationwide (OPEN) study, and report the demographic details and the initial steps of care for patients admitted with open fractures in the UK.

Introduction. Patient-reported outcome measures (PROMs) are increasingly being used to assess the quality of healthcare delivery in the United Kingdom. It is important when using PROMs to know the score of the background population against which any clinical intervention maybe benchmarked. The purpose of this study was to measure an elbow-specific PROM for the population of the South West Peninsula. Methods. We undertook a cross-sectional survey study of patients and healthcare professionals. Participants were asked to complete a simple demographic questionnaire and an Oxford Elbow Score for each elbow. Respondents with a history of elbow surgery, elbow injury, chronic elbow problems or an incomplete dataset were excluded from the study. Results. A total of 1782 respondents (3564 elbows) completed the survey. 574 questionnaires were excluded leaving 1208 individuals (2416 elbows) for analysis. The median scores for each decade group ranged between 46.74 and 48 out of 48. There was no significant difference in the score for age, gender or hand dominance. Conclusion. When using the Oxford Elbow Score to assess outcomes after surgery, a normal score should be used as the benchmark. This benchmark is independent of age, gender and hand dominance

Introduction. We aimed to identify genes associated with the development of ALVAL at relatively low levels of wear. Methods. At our unit all patients undergoing revision of a MoM hip prosthesis have periprosthetic tissue samples graded for ALVAL. Explants undergo volumetric wear testing of the bearing and taper surfaces. We identified patients with moderate/severe ALVAL who had been exposed to lower than the median wear rate of all recorded patients who had developed ALVAL (<3mm. 3. /year). This was termed the “ALVAL” group. We then identified all patients whose tissues had shown no signs of ALVAL. The patients in the two groups were sent buccal DNA collection kits. DNA was examined using next generation sequencing. Alleleic frequencies in the two groups were compared using Fisher's test and compared to a background UK population group (n=8514). We then conducted binary logistic regression with patient age, sex, primary source of debris (taper/bearing) and HLA genotype as the predictors. With the hypothesis that a cobalt/albumin metalloprotein acts as the epitope, we used validated binding prediction software to determine the relative affinities of the binding grooves created by different DQA1/DQB1 genetic combinations for albumin derived peptides. Given the protection that male sex and younger age appears to confer against ALVAL, we hypothesized that testosterone peptides may compete for these binding sites. Results. 28 ALVAL and 37 non ALVAL patients returned their samples for testing. The frequencies of DQA1∗05:05 and DQB1∗03:01 were significantly greater in the ALVAL groups(p=0.018). The variables positively associated with ALVAL were female sex(0.021), increasing age(0.003) and DQA1/DQB1 combinations with greater binding affinity for albumin fragments(0.03). Greater binding affinities for testosterone peptides were inversely related to ALVAL(0.05). Discussion. Common immune genotypes are associated with a greater risk of ALVAL. Conclusion. The evidence base on which MoM follow up protocols are based should be re-evaluated in light of these findings and future studies designed accordingly

A study to assess the clinical importance of asymmetric thigh creases as the sole clinical sign in the diagnosis of developmental dysplasia of the hip. METHOD. All consultant clinic letters have been saved on a hospital hard drive since 1999. This drive was searched for the terms “thigh crease” and “skin crease”. Irrelevant letters and referral letters describing factors that would indicate screening in our unit were excluded leaving those with the sole referral complaint of asymmetric thigh creases (ATC). We also reviewed the original referrals of developmental dysplasia of the hip (DDH) patients managed by open or closed reduction. These patients were identified through operative coding. All available hard copy notes were reviewed and patients with neuromuscular conditions or longitudinal deficiency were excluded. Results were inputted into an Excel spreadsheet and analysed by a statistician at the University of Sheffield assuming a background population incidence for DDH of 1 in 1000. RESULTS. 399 computer files containing the search terms were identified. Many contained whole clinics of patient letters. After exclusions we identified 229 patients with the sole referral complaint of ATC. Three of the 229 patients had DDH, which was not statistically significant (p=0.107). The majority of the normal patients had radiological investigations. Hard copy notes were available and relevant for 130 of the 289 operatively managed patients, of whom one was initially referred with the sole complaint of ATC. Orthopaedic specialist examination demonstrated all four patients initially referred with only ATC had decreased abduction and shortening. CONCLUSION. We suggest if the primary health care professional is not confident to exclude DDH in the patient with ATC there is justification for referral, but in the absence of other clinical features or risk factors in the orthopaedic consultation there is no need for further investigation or follow up

Aim: We have previously shown that long-term survival after hip fracture is highly dependent on age at the time of fracture and that fracture risk is similarly age-dependent. It has been suggested that the excess mortality occurs mainly during the first years after fracture, while mortality in a remaining life-time perspective is not well studied. The aim of this study was to evaluate short- and long-term mortality in relation to cause of death in a cohort of patients with hip fracture in comparison with the back-ground population. Methods: All adult patients suffering a hip fracture due to low energy trauma 1984–1985 in Malmö, Sweden were identified; 1029 cases (766 women, 263 men). The cases were compared with two age- and gender matched controls from the same background population, all alive and living in the catchment area when the hip fracture occurred. Date of death and cause of death were available through the national database, EPIC. Cases and controls were followed until death or up to 22 years. Results: The median survival was 4.4 yrs (+/− 0.2 [CI 95% 4.0–4.8]) in hip fracture patients and 7.7 yrs (+/− 0.2 [CI 95% 7.3–8.1]) in controls, equal to a median loss of 3.3 yrs. Mortality rate continued to be elevated for approximately 10 yrs, thereafter observed mortality approached expected mortality. Mean survival was 2.9 years shorter in fracture cases compared to controls (6.4 yrs (+/− 0.2 [CI 95% 6.0–6.8]) versus 9.4 yrs (+/− 0.2 [CI 95% 9.1–9.7])). Ischemic heart failure was the major underlying cause of death (25%) both among cases and controls. Conclusion: In hip fracture patients, excess mortality is evident both in the short- and long-term with an increased risk beyond 10 yrs. Nevertheless, the major causes of death were similar to that of controls

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

Tumour necrosis factor-α (TNF) is thought to play a role in aseptic loosening, the major cause of implant failure after total hip arthroplasty (THA). Natural sequence variations at –238 and –308 in the promoter region of the TNF gene are associated with differences in the susceptibility and severity of several TNF-mediated diseases. We tested whether carriage of the [less common] ‘A’ allele at –238 and –308 are associated with aseptic loosening after THA. 481 Caucasians (214 with failed implants versus 267 with radiologically intact implants) were recruited 11.7± 4.1 years after cemented THA for osteoarthritis. Genomic DNA was extracted from peripheral blood and genotyped for the –238 and –308 polymorphisms using the Taqman® 5′ nuclease method. 500 subjects from the local population were also genotyped using Taqman® to establish the background prevalence of the ‘A’ allele at each site. The carriage rate of –238A was 8.8% in the background population and 10.9% in the THA controls (P> 0.05). –238A carriage in the loosening group was 17.3% (odds ratio 1.72, 95% confidence interval 1.02 to 2.90). Carriage was highest (20.5%) in subjects with loosening of both the femoral and pelvic implant components (odds ratio 2.12; 1.17 to 3.83). The association of –238A with aseptic loosening was independent of age, sex, and amount of implant wear (Cox hazard ratio 1.49 (1.04 to 2.13; P=0.03)). Carriage of –308A was not associated with aseptic loosening. Genetic, as well as environmental factors, influence implant failure after THA. Whether the –238 polymorphism causes the biological change that predisposes to loosening, or is in linkage disequilibrium with such a locus, is not yet known

Aims

The aims of this meta-analysis were to assess: 1) the prevalence of coronavirus disease 2019 (COVID-19) in hip fracture patients; 2) the associated mortality rate and risk associated with COVID-19; 3) the patient demographics associated with COVID-19; 4) time of diagnosis; and 5) length of follow-up after diagnosis of COVID-19.

Background: Prospective population studies demonstrate that poor paraspinal muscle endurance increases the risk of developing first-time LBP and many CLBP studies also document excessive paraspinal muscle fatigability. The question arises as to whether this could have predisposed to chronic symptoms, through impaired spinal instability, especially in light of the wide inter-individual variation observed in the constitutionally determined paraspinal muscle fibre-type composition, which governs contractile performance. Objective: To determine whether CLBP-associated excessive paraspinal fatigue results from a paucity in the type I fibre content. Design: Control comparison using male subjects. Subjects: Thirty-five CLBP patients with Von-Korff Chronic Pain Scores of ≤ III (high level of residual function, despite pain, to negate effects of disuse atrophy), and 32 controls of similar age. Outcome measures: Fatigue-induced median frequency (MF) declines in the surface EMG signal, monitored bilaterally at L4 level during Biering-Sorensen- and 60%MVC- isometric fatigue tests. Percutaneous para-spinal muscle biopsies permitted histomorphometric comparisons. Results: Between-group differences were assessed using independent t-tests (p < 0.05). There were no differences for MF decline during the Biering-Sorensen -0.37(0.16) vs. -0.36(0.12), and the 60% MVC test −0.42(0.31) vs −0.51(0.29), and in the percentage number of type I fibres, 63.6% vs 64.3%, or percentage area occupied by type I fibres, 69.4% vs 67.2%, in the paraspinal muscles for patients and controls respectively (p> 0.05). Conclusion: Impaired CLBP-associated endurance is not the result of a constitutionally ‘adverse’ fibre-type composition
