Aims

The new COVID-19 variant was reported by the authorities of the UK to the World Health Organization (WHO) on 14 December 2020. We aim to describe the clinical characteristics and nosocomial infection rates in major trauma and orthopaedic patients comparing the first and second wave of COVID-19 infection.

Introduction and Aims: Patients with proximal femoral fracture are frail with multiple comorbidities and the anaesthesia often proves a greater challenge than the surgery itself. The aim was firstly, to determine whether general, compared to regional anaesthesia, caused a decrease in the mental test score (MTS) of patients with proximal femoral fracture. Secondly, what effect does a reduced MTS have on the general outcome for such patients.

Method: A prospective observational study was conducted in a regional trauma centre. One hundred and seventy consecutive patients over 60 years of age (mean age 82.6 years) were included. Age under 60 years was the only exclusion criterion. Pre- and post-operative (day five) MTS values were recorded by the same clinician.

Results: The MTS decreased by 2.43 points when general anaesthesia was administered compared to 1.5 for regional anaesthesia (p< 0.01 Mann Whitney). Lower post-operative MTS values were associated with increased mortality (p< 0.001 Mann Whitney). The greater the decrease in MTS (between pre- and postoperative values) the more likely it is that the patient will be institutionalised (p< 0.01 Mann Whitney).

Conclusion: Reduced mental function as observed after general anaesthesia is associated with increased mortality and institutionalisation. Thus the increased use of regional anaesthesia is advocated.

Aim: To compare extracapsular and intracapsular proximal femoral fractures in terms of pain scores, morbidity, mortality and total stay in hospital. Method: A prospective study over a 8 month period at a regional trauma centre. 170 patients over 60 years of age were included and their mean age was 82.6 years. Pain scores were recorded daily using a visual analogue scale. Results: Extracapsular fractures are more painful (p< 0.01 Mann-Whitney), associated with greater morbidity (p< 0.05 Chi-square, Fishers Exact) and are slower to recover (p< 0.01 Mann-Whitney) compared to intracapsular proximal femoral fractures. There was less mortality associated with undisplaced intracapsular fractures compared to all others (p< 0.01 Mann-Whitney). Conclusions: trochanteric proximal femoral fractures are more problematic medically and as such require more medical, nursing and resource input compared to intracapsular fractures. This knowledge can be used by the clinician to anticipate greater morbidity and as such treat more promptly.

Aims: A prospective study of the long term fixation of an all- polyethylene acetabular component with a 2mm rim for cement pressurisation, and methylmethac-rylate spacer beads for optimal cement mantle thickness. Methods: A consecutive series of 1348 hip arthroplasty patients aged between 23 and 94 (average 68 years) has been prospectively studied between 1993 and 2002. The cemented Ultima (De Puy) stem and cup were used via an anterolateral approach by 6 surgeons in a District General Hospital. Clinical and radiological assessment was at 0, 2, 5, 6, 7 and 8 years. Detailed assessment of the cup has been carried out to determine cases of clinical or radiological failure, quality of cement fixation to bone, and the profile of the cement mantle. Results: 875 patients have been followed up for a minimum of 2 years, 52 for a minimum of 8 years. The cumulative survival rate of the cup using revision for aseptic loosening as an endpoint at 8 years was 98% and using radiological evidence of loosening as an endpoint was 96%. There were no cases with less than 2 mm of cement mantle thickness and good quality bone cement interface was seen in all on the initial postoperative films indicating adequate pressurisation. Conclusions: The design of the Ultima polyethylene cup has been successful in achieving good cement pressurisation during implantation, an even cement mantle thickness, and clinical success rates which compare favourably with other cemented acetabular components.

Patients with proximal femoral fracture are frail with multiple comorbidities and the anaesthesia often proves a greater challenge than the surgery itself. The aim was firstly, to determine whether general, compared to regional anaesthesia, caused a decrease in the mental test score (MTS) of patients with proximal femoral fracture.

A prospective observational study was conducted in a regional trauma centre. 170 consecutive patients over 60 years of age (mean age 82.6 years) were included. Age under 60 years was the only exclusion criterion. Pre- and postoperative (day 5) MTS values were recorded by the same clinician.

Lower postoperative MTS values were associated with increased mortality (p< 0.001 Mann Whitney). The greater the decrease in MTS (between pre- and postoperative values) the more likely it is that the patient will be institutionalised (p< 0.01 Mann Whitney).

Reduced mental function as observed after general anaesthesia is associated with increased mortality and institutionalisation. Thus the increased use of regional anaesthesia is advocated.

Proximal femoral fracture (PFF) is already epidemic and projected to increase. 50% of patients fail to recover their preaccident mobility, resulting in protracted hospitalisation and exposure to nosocomial (hospital acquired) infections which impairs recovery further.

The aim of this study was to establish the rate at which patients with PFF regain mobility, the point at which they cease to recover and the incidence, time of onset and effect of nosocomial infections.

Recovery of mobility and nosocomial infection was prospectively recorded in 170 consecutive patients with PFF. 53% regained their best level of mobility within 6 days of admission, 81% within 8 and 91% within 14. The mean hospital stay was 21 days and delay to discharge was 14 days. During the delay, mobility deteriorated in 22% of patients and 58% developed nosocomial infection of which 18 were methicillin resistant staphylococcus aureus. The risk of infection doubled after a delay of 6 days.

Protracted hospitalisation after PFF is unhelpful and dangerous to patients and wasteful of healthcare resource. There is a small window of opportunity to discharge patients after PFF that is often missed. Thus there are often no beds for patients with acute fractures because they are occupied by patients who do not benefit from hospital admission or remain because they have acquired iatrogenic disease.
