This study demonstrates that intradiscal steroid injections do not improve the clinical outcome in patients with discogenic back pain compared with placebo.

BackgroundPatients in the extremes of old age with a femoral neck fracture represent a challenging subgroup, and are thought to be associated with poorer outcomes due to increased numbers of comorbidities. Whilst many studies are aimed at determining the optimum time for surgical fixation, there is no agreed consensus for those over 90. The aim of this study is to report the surgical outcome of this population, to understand the role surgical timing may have on operative outcomes using the orthopaedic POSSUM scoring system and to identify whether medical optimization occurs during the period of admission before surgery.Materials and methodsWe conducted a prospective observational study; data was collected from two district general hospitals over 32 consecutive months. All patients aged 90 and above who were deemed suitable for surgical fixation were included. Each one had their orthopaedic POSSUM score calculated at admission and at surgery, using their computerised and paper medical records. Assessment of outcome was based on morbidity and mortality at 30 days.ResultsA total of 146 consecutive patients above the age of 90 underwent surgery and were followed. The average age of the patients was 93 years, 123 (84 %) were female and 23 (16 %) male. Sixty-one patients were operated on within 24 h from admission, 52 patients within 24 and 48 h and 33 had surgery after 48 h from admission. In total, 21 deaths (14.4 %) were recorded and 81 patients (55.5 %) had a post-operative complication within 30 days. The orthopaedic POSSUM scoring system predicted 30-day mortality in 23 patients and morbidity in 83 patients. This gave observed to predicted ratios of 0.91 and 0.98 respectively. Overall, there was a small improvement in physiological scores taken just prior to surgery compared to those at admission. Mortality and morbidity rates were higher for those operated on or after 24 and 48-h cutoffs compared to those proceeding to surgery within 24 h (P = 0.071 and P = 0.021 respectively and P = 0.048 and P = 0.00011 respectively). When stratified according to their POSSUM scores, patients with scores of 41+ and surgery after 48 h had a significantly higher mortality rate than if they had surgery earlier (P = 0.038). Morbidity rates rose after 24 h of surgical delay (P = 0.026). Patients with a total POSSUM score between 33 and 40 exhibited a higher morbidity after a 24-h delay to surgery (P = 0.0064).ConclusionAs life expectancy increases, older patients are becoming commoner in our hospital systems. We believe the orthopaedic POSSUM scoring system can be used as an adjuvant tool in prioritising surgical need, and allow for a more impartial evaluation when changes to practice are made. Our findings show that timing of surgery has an important bearing on mortality and morbidity after hip surgery, and older patients with higher orthopaedic POSSUM scores are sensitive to delays in surgery.

We assessed the prevalence of abnormal ankle reflexes in 1074 adult patients attending orthopaedic clinics and related it to age. Those with possible pathological causes of reflex loss were excluded. The absence of one or both reflexes was significantly related to increasing age; all patients under 30 years had both reflexes. Few had absent reflexes between 30 and 40 years, but over 40 years, the proportion with both reflexes absent increased rapidly from 5% (40 to 50 years) to 80% (90 to 100 years). Unilateral absence did not show the same pattern of increase being 3% to 5% at 40 to 60 years and 7% to 10% at over 60 years. Our results suggest that a significant number of ‘normal’ adults have unilateral absence of an ankle reflex, but this finding is rare enough to be a definite clinical sign, irrespective of age.
