An analysis of virtual fracture clinics in orthopaedic trauma in the UK during the coronavirus crisis.

Virtual fracture clinics (VFC) are advocated by new orthopaedic (British Orthopaedic Association) and National Health Service (NHS) guidelines in the United Kingdom. We discuss benefits and limitations, reviewing the literature, as well as recommendations on introducing a VFC service during the coronavirus pandemic and into the future.A narrative review identifying current literature on virtual fracture clinic outcomes when compared to traditional model fracture clinics in the UK. We identify nine relevant publications related to VFC.The Glasgow model, initiated in 2011, has become the benchmark. Clinical efficiency can be improved, reducing the number of emergency department (ED) referrals seen in VFC by 15-28% and face-to-face consultations by 65%. After review in the VFC, 33-60% of patients may be discharged. Some studies have shown no negative impact on the ED; the time to discharge was not increased. Patient satisfaction ranges from 91-97% using a VFC service, and there may be cost-saving benefits annually of £67,385 to £212,705. Non-attendance may be reduced by 75% and there are educational opportunities for trainees. However, evidence is limited; 28% of patients prefer face-to-face consultations and not all have access to internet or email (72%).We propose a pathway integrating the VFC model, whilst having senior orthopaedic decision makers available in the ED, during normal working hours, to cope with the pandemic. Beyond the pandemic, evidence suggests the Glasgow model is viable for day-to-day practice. Cite this article: EFORT Open Rev 2020;5:442-448. DOI: 10.1302/2058-5241.5.200041.

Does a fixed offset hemiarthroplasty implant have any effect on pain and function in patients with a femoral neck fracture?

INTRODUCTION: Hip hemiarthroplasty is the commonest operation performed for a displaced intracapsular hip fracture in the UK. A variety of implants including fixed offset prostheses are utilised. There has been no study investigating the relationship between restoration of femoral offset and long term pain and function. This study aims to evaluate long-term pain and functional outcomes of a fixed offset hemiarthroplasty implant (the Exeter trauma system). PATIENTS AND METHODS: All patients were retrospectively reviewed from a prospectively collected database. In all, 338 patients met the criteria for evaluation. Patients native offset were calculated from the contralateral hip. Pain and functional outcomes were assessed using validated outcome measures. RESULTS: There were no differences found across a range of natural offsets for long-term pain and functional recovery. CONCLUSION: Our experience with the Exeter trauma system suggests that a 40 mm offset implant is a good standard offset to use.

Closing the gap on Achilles tendon rupture: A cadaveric study quantifying the tendon apposition achieved with commonly used immobilisation practices.

The relative benefits of surgical and conservative treatment of Achilles tendon rupture are widely debated. With modern conservative management protocols, the re-rupture risk appears to fall to one similar to surgical repair with negligible loss of function. Conservative management typically employs a period of time in an equinus cast with sequential ankle dorsiflexion in a functional orthosis. The optimal duration of immobilisation and rate of dorsiflexion is unknown. We aimed to quantify the change in Achilles tendon approximation achieved in common immobilisation techniques to assist the design of rehabilitation protocols. Twelve fresh-frozen cadaveric specimens had 2.5cm of Achilles tendon excised. The gap between the tendon ends were measured via windowed full equinus casts and compared with functional boots with successively removed heel wedges. The greatest tendon apposition was achieved with the equinus cast. Each wedge removed decreased the reapproximation by approximately 5mm. This paper supports the early use of maximal equinus casting in early management of acute Achilles tendon ruptures.

Radiological assessment of ankle syndesmotic reduction.

INTRODUCTION: The intraoperative assessment of adequacy of syndesmotic reduction is challenging. The aim of this study was to develop a radiographic measure based on the lateral ankle view to assess both the normal and abnormal relationship between the tibia and fibula after simulated syndesmotic malreduction and to evaluate the effect on commonly used mortise measurements. METHODS: Mortise and talar dome lateral radiographs were obtained in eight fresh-frozen cadaveric specimens before and following syndesmosis division and posterior fibular displacement of 2mm increments. Using the technique described, on the lateral radiograph the anterior fibular line ratio (AFL ratio) and posterior fibular line distance (PFL distance) were measured. Both measures were based on the anterior and posterior distal tibia articular margins and flat borders of the fibula. RESULTS: Inter- and intraobserver reliability of the AFL ratio and PFL distance measured almost perfect agreement. In all uninjured specimens the AFL lay just anterior to the midpoint of the tibia and the PFL intersected the posterior tibia articular margin or lay just anterior to it, not posterior. At 2, 4 and 6mm of posterior fibular displacement the decrease in AFL ratio and PFL distance showed significant differences between all pairwise comparisons. CONCLUSION: The proposed new measures of syndesmotic reduction are reproducible and capable of detecting from 2mm of sagittal fibula displacement and can be useful adjuncts in the assessment of syndesmotic reduction.
