Objective-To investigate the characteristics and outcomes of older patients with pelvic fracture admitted to medical and geriatric wards. Methods-All patients admitted to medical and geriatric wards with a pelvic fracture over a four year period were identified using the hospital clinical coding database. Data were collected from casenotes, hospital and Family Health Services Authority databases. Where available, pelvic radiographs were graded according to the Singh index. Results-The casenotes of 148 patients (126 women) were studied; 83% (n=123) of patients suVered a pelvic fracture in low energy trauma. Mean (SD) length of hospital stay was 21.3 (17.6) days. Single breaks of the pubic rami accounted for 47.2% (n=68) of all fractures. Inpatient mortality was 7.6% and at one year was 27%. There was a marked adverse eVect on the mobility of survivors with all patients using at least a walking stick at discharge and 51.1% (n=70) needing assistance for mobility. Although 70.9% (n=83) of patients admitted from home (or warden aided accommodation) were able to return there, 84.3% (n=70) of them required extra community support. Rates of institutionalisation rose from 20.9% (n=31) at admission to 35.8% (49/137) of survivors at discharge. Altogether 93% (n=107) of 115 patients, in whom adequate quality pelvic radiographs were available, were assigned a Singh index grade of 4 or less indicating the presence of osteoporosis. Conclusions-Pelvic fractures are often the result of low energy trauma. They are associated with appreciable inpatient and considerable one year mortality. They also have marked negative eVects on mobility in the short term. They result in increased levels of dependency in terms of higher levels of community support and rates of institutionalisation. On the evidence of Singh index grading, pelvic fractures are associated with low bone density. (Postgrad Med J 2000;76:646-650)

The use of oral corticosteroids is associated with an increased risk of fracture, but there is limited information on the relationship between corticosteroid dose, bone mineral density (BMD), and fracture. We examined this relationship in a community population (more than 50 years) taking oral corticosteroids for chronic lung disease. Details of corticosteroid use and lifestyle were obtained by questionnaire, general practice records, and patient interview. BMD was assessed at the lumbar spine and femur and vertebral fracture by morphometric X-ray absorptiometry. Of the 117 patients who participated (median age, 69), 48% were female. Fifty-eight percent had osteoporosis (a T score of less than -2.5), and 61% had a vertebral fracture. The presence of vertebral fracture was related to BMD at the femoral neck, with an odds ratio of 1.6 for a 1 SD reduction in BMD. The cumulative prednisolone dose ranged from 3.4 to 175 g and was strongly associated with vertebral fracture, with the odds ratio between the highest and lowest dose quartiles being 4.4 (95% confidence interval, 1.04, 18.8). The difference in femoral neck BMD between the same dose quartiles was only modest, however (0.5 SD; 95% confidence interval, 0.09, 0.94). In patients taking long-term oral corticosteroids for chronic lung disease, the relationship between vertebral fracture risk and BMD is similar to that seen in other populations. Cumulative prednisolone dose is strongly related to fracture risk, and this effect is independent of its more modest impact on BMD.
