What are the Salter-Harris classifications?
Of the five most common Salter-Harris fracture types, type II is the most common (75%) followed by types III (10%), IV (10%), type I (5%), and lastly, type V which is very rare. Males are more likely to be affected because they have an increased tendency to engage in high-risk activities.
How are the 3 different types of Le Fort fractures distinguished?
These fractures are classified into three distinct groups based on the direction of the fracture: horizontal, pyramidal or transverse. The pterygoid plate is involved in all types of Le Fort fractures. This may result in a pterygomaxillary separation. The absence of a pterygoid fracture rules out a Le Fort fracture.
What is a Type III fracture?
Type III: an open segmental fracture or a single fracture with extensive soft-tissue injury. Also included are injuries older than eight hours. Type III injuries are subdivided into three types: Type IIIA: adequate soft-tissue coverage of the fracture despite high-energy trauma or extensive laceration or skin flaps.
What is a Grade 1 fracture?
A grade I open fracture occurs when there is a skin wound that communicates with the fracture measuring less than one centimeter.
What is a Type Three 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 Type 4 injury?
In type IV separations, the fracture line is vertical. It extends through four distinct tissues/areas: metaphyseal bone, physeal cartilage, epiphyseal bone or cartilage and articular cartilage. The most common example of a type IV physeal injury is separation of the lateral condyle of the distal humerus.
What is a Type 1 or 2 fracture?
They categorized open injuries into the familiar three categories, based on wound size, level of contamination, and osseous injury, as follows: Type I = an open fracture with a wound less than 1 cm long and clean; Type II = an open fracture with a laceration greater than 1 cm long without extensive soft tissue damage.
What is a good score on a fracture assessment?
Fracture Classification. Score is a total of 3 components. Score ≤ 3 suggests nonoperative treatment, while score of 4 is indeterminate. Score ≥ 5 suggests operative treatment. For injury mechanism, the worst level is used, and the injury is additive.
How should we classify fractures?
For a given fracture, each physician should produce the same classification Descriptive Classification Systems •Examples –Garden: femoral neck –Schatzker: Tibial plateau –Neer: Proximal Humerus –Lauge-Hansen: Ankle Literature •94 patients with ankle fractures •4 observers •Classify according to Lauge Hansen and Weber
What percentage of interobserver agreement is appropriate for open fracture classification?
Literature on Open Fracture Classification • Interobserver agreement poor – Range 42-94% for each fracture • Least experienced- 59% agreement • Orthopaedic Trauma Fellowship trained- 66% agreement Brumback et al, JBJS-A, 1994
What are the different grades of open fractures?
Grades of Open Fractures 1 Grade I Open Fracture. 2 Grade II Open Fracture. 3 Grade III Open Fracture.
