Abstract
The diagnosis of a clinical scaphoid fracture is made when a scaphoid fracture is suspected, but radiographs are normal. Standard treatment in this scenario involves immobilization and repeat x-rays in 10–14 days. When repeat x-rays are also normal but a scaphoid fracture is still suspected clinically, the optimal management in children is unknown. Our objective was to characterize these patients and evaluate their management and outcomes.
A retrospective study was performed of all patients presenting to a tertiary paediatric center over a two year period with a diagnosis of wrist or hand pain. Charts were identified by ICD-10 diagnostic codes and reviewed for inclusion and exclusion criteria. Patients were included if they had clinical suspicion of a scaphoid fracture but two sets of x-rays negative for fracture within 14 days of injury.
Ninety-one children (mean age 13.2 years, SD: 2.2) were identified with a clinical scaphoid fracture. Mean follow-up was 7.1 weeks. Most patients (60%) were injured either from a fall while ambulating or from sports. Sixteen (18%) patients received CT or MRI at an average of 8.4 weeks post-injury (95%CI:5–15.3). All patients were immobilized for a mean of 5.4 weeks. No patients underwent surgery. Five patients (5.5%) were found to have a scaphoid fracture diagnosed by X-ray or CT at a mean of 5.7 weeks post-injury (range 4.3–6.6). Other carpal fractures or ligamentous injuries were identified in three patients (3%) by MRI or CT. Seventy percent of patients healed within 6 weeks of injury.
The majority of children presenting with clinical suspicion of a scaphoid fracture but 2 sets of X-rays negative for fracture healed with immobilization. While the incidence of true scaphoid fracture may be low in children, MRI or CT may be warranted for patients where clinical suspicion persists.
