Radiograph-negative ankle injury (peds)
Revision as of 17:04, 17 February 2017 by Rossdonaldson1 (talk | contribs)
Background
- Pediatric ankle injuries are common (>2 million ED visits in North America per year)[1]
- Historically, there has been concern about missing a potential growth plate fracture (Salter-Harris Type 1), which can rarely result in growth arrest[1]
- It was previously taught that the weaker physis would fail before the stronger ligamentous complex.[2]
- This was commonly treated with immobilization (casting), follow-up imaging, and orthopedic referral (as opposed to adult ankle sprain)
- Recent studies have questioned the need for this practice[3][4]
Clinical Features
- Lateral ankle pain after inversion injury
Differential Diagnosis
- Ankle fracture
- Salter-Harris fracture
- Ligimentous injury
- Contusion of bone or soft tissue
Evaluation
- Consider ankle x-rays
Management
Disposition
- Outpatient
