Hip fractures are a significant cause of mortality and morbidity in the elderly. Malnutrition is a major element of this but no consensus exists as to the detection or management of this condition. Reported incidence in elderly hip fracture patients varies widely between 9.0% and 88.6%. The aim of this study was to evaluate the nutritional status of 415 patients with operatively managed hip fractures and determine the prognostic relevance of admission serum albumin and total lymphocyte count (TLC) assays. Protein-energy malnutrition (PEM) was defined as serum albumin <
3.5g/dl and a TLC <
1,500 cells/mm3. Delay to operation, duration of in-patient stay, re-admission (<
3 months) and in-patient, 3- and 12-month mortality were assessed as outcome variables. Survival data was available for 377 patients at 12 months. Of 377 patients, 53% (n=200) had both a serum albumin and TLC levels taken at admission, while 47% (n=177) had not. The incidence of PEM was 51%. Inhospital mortality for PEM patients was 9.8%, compared with 0% for patients with normal values of both laboratory parameters. Older patients were more likely to have lower albumin (p=0.017) and TLC (p=0.023). Nursing home patients were also more likely to have lower albumin (p=0.033). Multivariate analysis revealed a significant difference in 12-month mortality, with patients who had both a low albumin and a low TLC 4.6 times (95% CI: 1.0–21.3) more likely to die within 12 months postoperatively than patients who had normal values of both laboratory parameters. This was significant after adjusting for age, gender and domicile (p=0.049). Serum albumin and TLC in combination are accurate predictors of 12-month mortality in hip fracture patients. These results highlight the relevance of assessing the nutritional status of patients with hip fractures at the time of admission and emphasises the relationship between nutrition and outcome.
In the past autogenous bone grafting has been the mainstay of treatment in patients with fracture non-unions. The harvesting of bone graft is, however associated with significant donor site morbidity. Recently there has been much interest in the use of synthetic osteo-inductive agents. We performed a review series of thirteen patients with sixteen non-unions in whom op-1, a bone morphogenetic protein (available commercially as Osigraft) was used to promote union. This was a retrospective chart review and union was judged on the basis of radiological union as reported by the radiology department and documented by the surgeon responsible and clinical union based on the ability to weight bear with minimal or no pain as documented in the patients’ records. At nine months twelve of sixteen non-unions (75%) had achieved clinical and radiographic union. Three patients had repeat grafting, all of whom went on to union. Mean time to grafting after initial treatment for all patients was 8.9 +/−6.1 months. Mean time to union was 5.1 +/− 1.6 months. We conclude that the use of osteo-inductive agents, in particular BMP-7 (op-1) results in good clinical and radiological outcomes. What remains unclear is whether they are superior to the traditional approach of autogenous grafting.
There is little published data concerning long-term outcome in pyogenic spinal infection. Previous studies have used either neurological outcome in isolation, or non-validated quality of life measure instruments yielding data that is difficult to interpret. To assess long-term outcome following pyogenic spinal infection through standardised outcome measures, Oswestry Disability Index (ODI) and Short Form-36 (SF-36) were utilised. All cases of pyogenic spinal infection presenting to a single institution over the period 1993–2003 were retrospectively identified. Inclusion in each case was based on consistent clinical, imaging and microbiology criteria. The follow-up was by clinical review, American Spinal Injury Association (ASIA) classification, ODI and SF-36. The outcome was compared to normative data for the Irish population. Twenty-nine cases of pyogenic spinal infection were identified. Nineteen patients (66%) had an adverse outcome at a median follow-up of 61 months, despite only 5 patients (17%) who had persistent neurological deficit according to ASIA classification. A significant difference in SF-36 PF (physical function) scores was observed between patients with adverse outcome and those who recovered (p=0.003). SF-36 scores failed to reach those of a normative population, even after apparent full recovery. A strong correlation was observed between ODI and SF-36 Physical Function scores (rho=0.61, p<
0.05). Seventeen percent (n= 5) of admissions resulted in acute sepsis-related death. Delay in diagnosis of spinal infection (p= 0.025) and neurological impairment at diagnosis (p<
0.001) were associated with neurological deficit at follow-up examination. Previous spinal surgery was a significant predictor of adverse outcome in patients requiring readmission <
1 year (p= 0.018). The finding of high rates of adverse outcome and using SF-36 and ODI suggests under-reporting of poor outcome in other series. We advocate use of validated standardised spinal outcome questionnaires to accurately assess long-term outcome and facilitate comparison between case series.
