In current practice in the UK there are three main approaches to investigating suspected scaphoid fractures not seen on initial plain film x-rays.

Our unit uses the VFC model. We aimed to evaluate its efficiency, safety, clinical outcomes and economic viability.

All patients attending the emergency department with either a confirmed or suspected scaphoid fracture between March and December 2020 were included (n=305). Of these 297 were referred to the VFC: 33 had a confirmed fracture on x-ray and 264 had a suspected fracture.

Of the suspected fractures reviewed in VFC 14% had an MRI organised directly owing to a high-risk presentation, 79% were brought for fracture clinic review and 17% discharged with an alternative diagnosis such as osteoarthritis.

Of those subsequently reviewed in fracture clinic at two weeks: 9% were treated as scaphoid fractures (based on clinical suspicion and repeat x-rays), 17% had MRI or CT imaging organised, 5% did not attend and 69% were discharged.

Overall, 17% of cases initially triaged, had further imaging – 41 MRIs and 5 CTs. MRI detected: 5% scaphoid fracture, 17% other fracture, 24% bone contusion, complete ligament tear 10%, partial ligament tear 39% and normal study 10%. The results of MRI minimally affected management. 3 patients were taken out of plaster early, 1 patient was immobilized who was not previously and no patients underwent operative management.

In the following 12-month period one patient re-presented with a hand or wrist issue.

This approach avoided 218 MRIs, equating to £24000 and 109 hours of scanner time.

VFC triage and selective use of MRI scanning is a safe, efficient and cost-effective method for the management suspected scaphoid fractures. This can be implemented in units without the resource to MRI all suspected scaphoid fractures from the emergency department.

Virtual Fracture Clinic (VFC) is a consultant-led orthopaedic trauma outpatient triage and management service. The use of VFC has recently become commonplace in the United Kingdom. It allows multiple referral sources to the orthopaedic team, with clinical information and imaging reviewed by a consultant in VFC who formulates an appropriate management plan with the patient contacted; either to attend clinic for consultation or discharged with advice over the phone. The VFC is more efficient than a traditionally delivered outpatient fracture clinic service. We have utilized VFC for 1 year at our hospital, East Kent University Hospital Foundation Trust (EKHUFT), and undertook a closed loop audit to evaluate the service and highlight potential areas of improvement. The Objective of the study was to identify whether the implementation of new re-designed VFC referral guidelines together with teaching set across one of the hospitals in EKHUFT improved the effectiveness and standards of VFC referrals.

An initial audit was performed of all referrals made to VFC over a 2 weeks period in December 2018. Changes to the VFC referral pathway were implemented, and teaching sessions performed by the orthopaedic team to all referring units, including minor injury units (MIU) and the emergency department (ED). After implementation, re-audit of VFC referrals was performed in February 2019 over a similar 2 weeks period. Patient demographics, diagnosis and outcomes were collected from the online patient record with images reviewed using PACS software.

Following intervention, referral rates dropped by 27.7% (136 vs 188 patients) over the 2 weeks periods. Patient demographics, injury type and severity remained the same between the 2 groups. 51.5% (70/136) did not meet VFC pathway criteria after the intervention and were considered inappropriate, compared to 70% in the original group. 15.4% (21/136) referrals could have been managed in the emergency department using the new guidelines and leaflet discharge. 5.1% (7/136) of the referrals should have been referred to orthopaedic on-call acutely and 22% (30/136) of the referrals had a soft tissue injury or no injury identified. This did not change between the 2 groups despite intervention.

Referring MIU and ED units require continued support and teaching over a prolonged time period to hopefully see further improvements. Immediate hot reporting of radiographs may further benefit the service, but staffing and funding issues particularly out of hours, means this remains an aspiration.

Background

Predicting length of stay (LOS) is key to providing a cost effective and efficient arthroplasty service in an era of increasing financial constraint. Previous studies predicting LOS have not considered enhanced recovery protocols in elective hip and knee arthroplasty. Our study aims to identify patient variables in the pre and peri-operative period to predict increased LOS on patients enrolled into the standardised Chichester and Worthing Enhanced Recovery Programme (CWERP).

Aim

We aim to show that our series of Avon Patellofemoral Joint Replacements (APFJR) with over 5 year follow up, have comparable functional, radiological and revision rate results to other published reports.

This study aims to show that our series of Avon Patellofemoral Joint Replacements (APFJR) with over 5 year follow up, have comparable functional, radiological and revision rate results to other published reports.

Retrospective analysis occurred for all consecutive cases of APFJR from October 1999 and January 2010; all operations were performed by the senior author (AL). Each patient had both clinical and radiological follow up. Patient demographics, pre and post op Oxford Knee scores and complications were all recorded. An independent post-operative radiological review took place to check for loosening and progression of disease. Revision to Total Knee Replacement was taken as the endpoint.

83 consecutive APFJR's were implanted in 56 patients for established isolated patellofemoral arthritis. The average age was 68.2(34-95) with 18 males and 38 females. The mean follow-up was 5.4 years (1.25 to 11). There were 5 revisions with the five-year survival rate being 95.2% (95% confidence interval 88.12% - 99.88%). The median Pre Op Oxford knee score was 17 of 48 points (interquartile range 11 to 21) showed significant improvement when compared to the median Post Op Oxford knee score of 35 (interquartile range 26 to 41). There was one superficial infection, no deep infections and one transient sciatic nerve palsy. These results compare very closely to those in the designing surgeon's series (Ackroyd et al JBJS Br 2007).

These results reveal satisfactory survivorship and functional outcome results in the medium term leading to increased confidence in the use of this patellofemoral arthroplasty.
