Mr Dawe and the Oving Clinic are pleased to be starting the first Standing CT scanning service based in West Sussex, with a visiting scanner from the Standing CT company.
Standing CT scanning has several benefits compared to both conventional X-rays as well as some advantages over both conventional CT scans and MRI. The scanner uses a technique called 'cone-beam CT' scanning which is different to the conventional type of CT scans which re commonly performed in large scanners at major hospitals.
The Cone-beam CT scan takes around 1 minute to perform. It uses less radiation than a set of weightbearing Xrays and much less radiation than a CT scan.
The major benefit of standing CT is that the foot is imaged in the position in which it is used, i.e. you are standing up to have the scan done not lying down. Conventional CT scans can only show the foot in a resting position where it takes a different shape, arthritic joints might not show-up on a basic scan, but are more easily seen on standing CT. This allows the detection of subtle joint problems which can be difficult to find using other imaging modalities.
These scans can help with the understanding of many foot problems such as foot and ankle injuries or fractures, ankle arthritis, midfoot arthritis, bunions, plantar fasciitis and stress fractures, as well as foot deformities such as the painful flat foot and high-arched or cavus feet and toe problems.
Most major insurance companies now recognise standing CT as a new image modality and for self-funding patients this scan can be used to reduce the costs of treatment by reducing the use of conventional X-rays and MRI scans.

Standing Cone Beam CT scanning can also be used to help decide on treatments for conditions affecting all lower limb conditions including hip and knee arthritis, as well as for the assessment of problems with joint replacements. Furthermore the same scanner can be used for rapidly assessing hand and wrist problems such as injuries or arthritis.
USA Visitation - Arthrex - Coetzee
Mr Dawe visited the USA in February 2019. He visited the world renowned Dr J Chris Coetzee for a surgical visitation at the Egan Orthopaedic Centre, part of Twin Cities Orthopaedics and joined with the Minnesota Vikings. He then was one of the first UK surgeons to visit the Arthrex facility in Naples Florida in order to spend time in their new surgical development centre. Thanks to Dr Coetzee and to Arthrex for a most informative and useful trip.
A small team of researchers including Mr Dawe have won first prize for their research presentation at the 2018 British Orthopaedic Foot and Ankle Society Meeting. The research used a zero-gravity treadmill (a treadmill which blows air at your legs and can simulate you weighing less, all the way to being completely weight-less) in order to demonstrate the benefits of weight-loss in foot and arthritis. Patients in the study found a reduction of around 40% of their pain during the test. This has provided further evidence of the benefits of weight loss in improving foot and ankle pain.

Mr Dawe has been invited to speak to all comers at the Nuffield Chichester on the 30th October. His talk will cover many conditions affecting the foot and ankle such as painful bunions, painful toes, heel pain and the myriad of different treatments available for foot and ankle pain.
