Addenbrooke's Hospital, the Major Trauma Centre for the East of England Trauma Network, received 1070 major trauma patients between 1st January and 31st December 2014. In order to improve care, an audit was performed of 59 patients meeting our own selection criteria for orthopaedic polytrauma between 1st January 2013 and 31st December 2013. The Cambridge Polytrauma Pathway was devised through NCEPOD guidelines, literature review, internal and external discussion. It facilitates provision of best practice Early Appropriate Care, encompassing - multidisciplinary consultant decisions around the patient in our Neurological and Trauma Critical Care Unit, early full body trauma CT scans, serial measurements of lactate and fibrinogen levels, and out-of-hours orthopaedic theatre reserved for life-and-limb threatening injuries. Re-audit was conducted of 15 patients meeting selection criteria, admitted between 1st October 2014 and 31st March 2015. Significant improvements in recording of lactate and fibrinogen were demonstrated, both on admission (lactate - p<0.000, fibrinogen - p=0.015), and preoperatively (lactate - p=0.003, fibrinogen - p=0.030). Time to trauma CT was unchanged (p=0.536) with a median time to CT of 0.53h at re-audit (IQR 0.48-0.75). The number of patients receiving definitive orthopaedic intervention out-of-hours reduced from 8 to zero (p=0.195). The approach of facilitating management decisions to be made at early daytime MDT meetings has been adopted. It is anticipated that this pathway will improve outcomes in orthopaedic polytrauma patients and it is recommended that either the GOS-E, or the EQ-5D scoring systems be introduced to assess this., (Crown Copyright © 2016.

The St. Leger total knee replacement (Zynergy Orthopaedics Ltd, Rotherham, UK) was developed as a cheaper alternative to similar implants of its time. Between October 1993 and June 1999, 144 St. Leger total knee replacements were implanted into 114 patients. Seventy-three patients (99 knees) were recalled for assessment (mean follow-up of 10.2 years). Eighteen patients had had their prostheses revised, 11 had died and 12 were lost to follow-up. Functional Score showed 90% poor results and the Objective Knee Score showed 31% poor results. Radiological assessment identified 12 arthroplasties that had failed and 58 that required close follow. Kaplan-Meier cumulative survivorship was 87% at 10 years. The St. Leger knee replacement did not perform as well as others of the same generation and was not worth the initial financial savings.
