Paediatric fractures are common and can cause significant morbidity. Socioeconomic deprivation is associated with an increased incidence of fractures in both adults and children, but little is known about the epidemiology of paediatric fractures. In this study we investigated the effect of social deprivation on the epidemiology of paediatric fractures.

We compiled a prospective database of all fractures in children aged < 16 years presenting to the study centre. Demographics, type of fracture, mode of injury and postcode were recorded. Socioeconomic status quintiles were assigned for each child using the Scottish Index for Multiple Deprivation (SIMD).

We found a correlation between increasing deprivation and the incidence of fractures (r = 1.00, p < 0.001). In the most deprived group the incidence was 2420/100 000/yr, which diminished to 1775/100 000/yr in the least deprived group.

The most deprived children were more likely to suffer a fracture as a result of a fall (odds ratio (OR) = 1.5, p < 0.0001), blunt trauma (OR = 1.5, p = 0.026) or a road traffic accident (OR = 2.7, p < 0.0001) than the least deprived.

These findings have important implications for public health and preventative measures.

Many psychological factors have been associated with function after joint replacement. Personality is a stable pattern of responses to external conditions and stimuli. The aim of this study was to investigate the relationship between personality, joint function, and general physical in patients undergoing total hip (THR) and knee replacement (TKR).

We undertook a prospective cohort study of 184 patients undergoing THA and 205 undergoing TKA. Personality was assesed using the Eysneck Personality Questionaire, brief version (EPQ-BV). Physical health was measured using the EuroQol (EQ-5D). Joint function was measured using the relevant Oxford Score. Outcomes were assessed at six months. Multivariable models were constructed.

The stable introvert personality was most common. Unstable introverts had poorer pre-operative function with hip arthrosis, but not knee arthrosis. Personality was not directly associated with post-operative function – the only independent predictors were pre-operative function (p=0.002) and comorbidity (p<0.001). While satisfaction after TKR was associated with personality (p=0.026), there was no association after THR (p=0.453). The poorest satisfaction was in those with the unstable introvert personality type.

Personality was a predictor of preoperative status. It did not have a direct association with postoperative status, but may have as preoperative function was the main predictor of postoperative function, personality may have had an indirect effect. Personality was also a predictor of satisfaction after TKR. This suggests that predicting satisfaction after knee replacement is more complex. Therefore certain patient may benefit from a tailored preoperative education to explore and manage expectations.

Introduction

Osteoarthritis continues to be a major cause of pain and disability. The pathological processes leading to the end-stage of joint degeneration remain poorly understood. Advances in radiological imaging have the potential to improve understanding of the structural and functional changes observed in OA. The aim of this study was to describe the microarchitecture of the femoral head in osteoarthritis.

Methods

Twenty osteoarthritic femoral heads underwent micro-computed tomography scanning at 30µm. Four parameters of micro-architecture and structure were determined: bone volume ratio (BV:TV), trabecular thickness, structural model index and degree of anisotropy. The femoral head was divided into 27 cubic volumes of interest. Analysis of variance (ANOVA) was used to assess differences between regions. Cystic and sclerotic changes were assessed qualitatively.
