SplintER Series: Salter-Harris Fractures

Type II Salter-Harris fracture

A 6 year-old boy presents with left wrist pain after he fell off the monkey bars onto an outstretched hand. You obtain wrist x-rays and see an abnormality. What is the most likely diagnosis, differential diagnosis, and management plan?

Displaced Type II Salter-Harris fracture of distal radius

Closed reduction is performed by recreating the fracture pattern (in this case, hyperextending the wrist) and with traction, the distal radial fragment can be brought over the proximal fragment and into position. This particular case can prove to be a more difficult reduction as only the radius is fractured. Commonly used splints are the volar or sugar tong (examples here).

If appropriate reduction is achieved, discharge home and follow up with orthopedics in 7-10 days [1]. Pediatric patients heal rapidly and full return of normal activity can be expected if treated properly, regardless of how dismal the initial fracture pattern looks (see discussion for more details).

The Salter-Harris classification system characterizes the relationship of the fracture line to the growth plate (physis) and the likelihood of impact on growth potential, from the least likely (type I) to most (type V). The physis is weaker than surrounding ligaments, so the impact of forces are more likely to cause fractures than tears in pediatric patients [1].

Always have a high index of suspicion while growth plates are open (girls 13-15, boys 15-17). Thankfully, Dr. Salter left his name as a perfect building block for remembering the types.
