What are the classifications of growth plate fractures?
The Salter-Harris system classifies growth plate fractures into five groups: type I, fracture through the growth plate; type II, fracture through the growth plate and metaphysis; type III, fracture through the growth plate and epiphysis; type IV, fracture through the growth plate, epiphysis and metaphysis, and type V.
What is a Salter-Harris type 5 fracture?
Type V. The rarest form of Salter-Harris fracture, Type V happens when your child’s growth plate is compressed or crushed. Since this is a severe injury, it can lead to the hardening of the growth plate, leading to bone growth arrest. This means your child’s bone may not be able to continue growing.
What are the 5 types of growth plate fractures?
Types of growth plate fractures
- Transverse fractures through the growth plate (Salter 1)
- Fractures through the metaphysis and growth plate (Salter 2)
- Fractures through the epiphysis and growth plate (Salter 3)
- Fractures through the epiphysis, metaphysis and growth plate (Salter 4)
How many types of Salter-Harris fractures are there?
There are five common types of Salter-Harris fractures, which range in severity according to their potential for growth disturbance. Type I fractures are least likely to impair bone growth, while type V is the most likely to disturb a child’s bone growth.
What is Salter-Harris Type 2 fracture?
A type II Salter-Harris fracture is the most common pediatric physeal fracture, occurring frequently in children over 10 years of age. This fracture breaks at an angle, cutting through most of the growth plate and the metaphysis, the area above the growth plate.
How many Salter-Harris classifications are there?
There are nine types of Salter–Harris fractures; types I to V as described by Robert B Salter and W Robert Harris in 1963, and the rarer types VI to IX which have been added subsequently: Type I – transverse fracture through the growth plate (also referred to as the “physis”): 6% incidence.
How long does it take for a Salter-Harris type 1 fracture to heal?
Healing usually takes about 4-6 weeks, at which time it will be safe for your child to return to sports and activities. It is very rare for a Salter-Harris I fracture to cause problems with the growth of the distal fibula (less than 1% of fractures).
What is a Level 3 fracture?
A type III fracture (see the images below) is a fracture through the physis and epiphysis. This fracture passes through the hypertrophic layer of the physis and extends to split the epiphysis, inevitably damaging the reproductive layer of the physis.
What is a Salter-Harris type III fracture?
Salter-Harris type III fractures are an uncommon, intraarticular fracture physeal fractures that occur in children. The fracture line is often obliquely oriented through the epiphysis to the physis where it will take a horizontal orientation extending to the edge of the physis.
