ClinConnect Summary

The scaphoid bone is an obliquely orientated bone on the radial (thumb) side of the wrist, between the distal carpal row and the radius. Wrist injury is a common presentation to the Emergency Department (ED) in the UK. Amongst these patients, the scaphoid is the most commonly fractured carpal bone, accounting for 51-90% of carpal fractures and between 2-7% of all fractures.

Given that: 1) various clinical complications may arise from a misdiagnosed scaphoid fracture; and 2) clinical and radiographic diagnosis of scaphoid fracture is often challenging, particularly at the time of presentati...

Eligibility criteria

• Inclusion Criteria:
• Every patient aged 16 years or over presenting at A\&E/UCC with clinical history and examination consistent with a suspected scaphoid fracture but negative findings on the initial 4-view plain x-ray. It is considered that a patient has suspected scaphoid fracture if at least one of the following criteria are present:
• • Isolated pain / tenderness over the Anatomical Snuff Box (ASB) or Scaphoid Tubercle or pain in the scaphoid region during axial loading of the 1st metacarpal.
• • History of recent fall (\< 14 days) on an out-stretched hand (FOOSH), wrist injury or poor history associated with examination findings suggestive of scaphoid fracture.
• Furthermore, only patients that present at A\&E/UCC during the following schedule of MRI normal working hours will be included in the study:
• • Patients screened for the study at A\&E/UCC on weekdays after 7.30 am and before 6 pm;
• • Patients screened for the study at A\&E/UCC on weekends or Bank Holidays after 9 am and before 4 pm.
• Exclusion Criteria:
• • Patients presenting outside GSTT's catchment area who are not willing to be followed-up at GSTT;
• • Patients with a confirmed scaphoid fracture following the initial 4-view plain x-ray;
• • Patients with confirmed ipsilateral upper limb injury/injuries (e.g. wrist/forearm/arm injury) following initial conventional x-ray examination(s) - regardless of the findings around the suspected scaphoid fracture.
• • Patients with suspected scaphoid fracture not admitted through A\&E at St Thomas' Hospital or Urgent Care Centre (UCC) at Guy's Hospital;
• • Patients who lack capacity to give consent or participate in the study;
• • Patients that are already taking part in a Clinical Trial of an Investigational Medicinal Product (CTIMP);
• • Prisoners.
