Introduction: As the number of patients sustaining hip fractures increases, interventions aimed at improving patient comfort and reducing complication burden acquire increased importance. Frailty, cognitive impairment, and difficulty in assessing pain control characterize this population. In order to inform future care, a review of pain assessment and the use of preoperative intravenous paracetamol (IVP) is presented. Materials and Methods: Systematic review of preoperative IVP administration in patients presenting with a hip fracture. Results: Intravenous paracetamol is effective in the early management of pain control in the hip fracture population. There is a considerable decrease in use of breakthrough pain medications when compared with other pain relief modalities. Additionally, IVP reduces the incidence of opioid-induced complications, reduces length of stay, and lowers mean pain scores. Another significant finding of this study is the poor administration of all analgesics to patients with hip fracture with up to 72% receiving no prehospital analgesia. Discussion: The potential benefits of IVP as routine in the early management of hip fracture-related pain are clear. Studies of direct comparison between analgesia regimes to inform optimum bundles of analgesic care are sparse. This study highlights the need for properly constructed pathway-driven comparator studies of contemporary analgesia regimes, with IVP as a central feature to optimize pain control and minimize analgesia-related morbidity in this vulnerable population.

Category: Ankle, Ankle Arthritis Introduction/Purpose: Topographic pain mapping has gained popularity during 20th century, providing opportunities for patients to demonstrate spatial distribution of pain. Despite this, evidence of clinical application in orthopaedics remains largely limited to spinal pathologies. We investigate how clinician interpretation of routine radiological studies compares to patient pain mapping in ankle arthritis. Methods: Between 2014 and 2016 we identified 21 patients ultimately diagnosed with ankle arthritis, who underwent comprehensive gait analysis (including topographic pain mapping) on referral to our institution. Patients were requested to map up to three pain areas, assigning a visual analogue score (VAS) of 0-10, to signify severity of pain in each area. A consultant orthopaedic foot and ankle surgeon, and orthopaedic trainees undertook blinded evaluation of relevant radiological studies, estimating patients’ mapping and VAS scores on the basis of radiological pathology. For the purpose of analysis findings were applied to five distinct regions around the ankle: three anterior (antero-medial; central; and antero-lateral), lateral and medial. Results were correlated between the different assessors, as well as to the patients’ pain mapping, using Spearman’s Rho & Kendall Tau correlation statistics, significance taken as p=0.05). Correlation to patient pain mapping was even poorer, with radiological assessment consistently over- estimating symptom severity (p=>0.05). Conclusion: There is a statistically strong correlation between topographic pain mapping and radiological evaluation of ankle arthritis. We strongly recommend that additional pathology around the ankle is excluded by use of pre-operative MRI imaging prior to surgery for ankle arthritis. Pain from ankle arthritis appears to mask additional soft tissue pathology surrounding the ankle noted on MRI scan.
