Hemiarthroplasty and proximal femoral fixation are common procedures performed in trauma units, but there is very little information regarding post-operative pain experience. Pain control is a keystone in the successful management of hip fractures. A sound strategy of pain management is easier to implement in patients where pain levels can be predicted, allowing for an effective balanced analgesic regime.

Analysis was performed on patients presenting with a hip fracture in two hospitals. Patients with a diagnosis of dementia were excluded. Post-operative pain scores were taken from patient observation charts using a verbal analogue scale. Post-operative opiate consumption was calculated from inpatient drug charts.

357 patients were included, 205 patients underwent a cemented hemiarthroplasty (HG) and 152 had fixation with a dynamic hip screw (DG). No significant difference was found in the length of hospital stay. HG patients recorded a mean morphine requirement of 20.2mg compared with 40.3mg for the DG group. Although the early pain score difference was significant (p=0.009), after 4 days, the scores were equivalent. This may support the notion of non-surgical factors determining the total length of hospital stay.

The reason for the elevated pain scores and higher morphine requirement in the DHS group remains unclear. One theory is the fracture site still exists, and it is possible that pre-existing hip arthritis may continue to be symptomatic. It is important to recognise the difference in pain experienced between the groups and analgesia should be tailored towards the individual, allowing for improved peri-operative surgical care and patient experience.

Background

Dislocation is a major complication following total hip arthroplasty (THA). Aetiology is multi-factorial, but increasing femoral head size may result in lower dislocation rates. The latest England and Wales National Joint Registry (NJR) annual report has highlighted a statistically significant increase in the use of femoral heads of size 36mm+ from 5% in 2005 to 26% in 2009, together with an increase in the use of the posterior approach. The aim of this study was to determine whether national dislocation rates have fallen over the same period.

Methods

Hospital episode statistics (HES) data for England was analysed so as to determine trends in national rates of 3-, 6-, 12- and 18-month dislocation rates following primary THA performed between 2005 and 2009 (247,546 THAs). 18-month revision rates were also examined.

Patient-reported outcome measures (PROMs) are increasingly being used to assess functional outcome and patient satisfaction. They provide a framework for comparisons between surgical units, and individual surgeons for benchmarking and financial remuneration. Better performance may bring the reward of more customers as patients and commissioners seek out high performers for their elective procedures. Using National Joint Registry (NJR) data linked to PROMs we identified 22 691 primary total knee replacements (TKRs) undertaken for osteoarthritis in England and Wales between August 2008 and February 2011, and identified the surgical factors that influenced the improvements in the Oxford knee score (OKS) and EuroQol-5D (EQ-5D) assessment using multiple regression analysis. After correction for patient factors the only surgical factors that influenced PROMs were implant brand and hospital type (both p < 0.001). However, the effects of surgical factors upon the PROMs were modest compared with patient factors. For both the OKS and the EQ-5D the most important factors influencing the improvement in PROMs were the corresponding pre-operative score and the patient’s general health status. Despite having only a small effect on PROMs, this study has shown that both implant brand and hospital type do influence reported subjective functional scores following TKR. In the current climate of financial austerity, proposed performance-based remuneration and wider patient choice, it would seem unwise to ignore these effects and the influence of a range of additional patient factors.

Increased femoral head size may reduce dislocation rates following total hip replacement. The National Joint Registry for England and Wales has highlighted a statistically significant increase in the use of femoral heads ≥ 36 mm in diameter from 5% in 2005 to 26% in 2009, together with an increase in the use of the posterior approach. The aim of this study was to determine whether rates of dislocation have fallen over the same period. National data for England for 247 546 procedures were analysed in order to determine trends in the rate of dislocation at three, six, 12 and 18 months after operation during this time. The 18-month revision rates were also examined.

Between 2005 and 2009 there were significant decreases in cumulative dislocations at three months (1.12% to 0.86%), six months (1.25% to 0.96%) and 12 months (1.42% to 1.11%) (all p < 0.001), and at 18 months (1.56% to 1.31%) for the period 2005 to 2008 (p < 0.001). The 18-month revision rates did not significantly change during the study period (1.26% to 1.39%, odds ratio 1.10 (95% confidence interval 0.98 to 1.24), p = 0.118). There was no evidence of changes in the coding of dislocations during this time.

These data have revealed a significant reduction in dislocations associated with the use of large femoral head sizes, with no change in the 18-month revision rate.
