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.
