Study Notes
Pediatric Fractures Overview
- Pediatric bones exhibit skeletal immaturity, which is crucial for growth and development.
- The presence of growth plates is unique to children’s bones and impacts treatment decisions and potential complications.
- Fractures involving growth plates may influence long-term growth and development outcomes.
Salter Harris Classification
-
Salter Harris I:
- Fracture occurs solely through the growth plate.
- Generally has a good prognosis; may not be clearly visible on imaging.
-
Salter Harris II:
- Involves both the growth plate and metaphysis.
- Most common type with a good prognosis.
-
Salter Harris III:
- Affects the growth plate and extends into the epiphysis.
- Poor prognosis due to risks of premature fusion and potential for osteoarthritis.
-
Salter Harris IV:
- Fracture affects growth plate, metaphysis, and epiphysis.
- Similar to Type III with a negative prognosis due to joint space involvement.
-
Salter Harris V:
- A crush injury affects the growth plate.
- Poor prognosis, often occult on imaging, with risks of vascular injury and early fusion of growth plates.
Radiographic Examples
-
Salter Harris Fracture II:
- X-ray shows fracture extending through the growth plate and metaphysis.
- Common in skeletally immature patients with a good prognosis.
-
Salter Harris Fracture III:
- X-ray displays fracture involving both growth plate and epiphysis.
- Poor prognosis, with risks of joint issues.
-
Salter Harris Type I (SCFE):
- X-ray reveals fracture in the proximal femoral growth plate.
- Most prevalent in African-American boys and obese children; resembles "ice cream slipping off the cone."
- Requires close medical intervention due to risks.
Incomplete Fractures
-
Torus (Buckle) Fracture:
- Involves partial compression of the bone cortex, common in children.
- Example includes buckling of the distal radial cortex visible on wrist x-ray.
-
Greenstick Fracture:
- Affects only one side of the cortex, frequently seen in pediatric patients.
- Example includes partial fracture of the distal radius visible on wrist x-ray.
Supracondylar Fractures
- Most common type of elbow fracture in children.
- Diagnosis includes observation of the posterior fat pad sign.
- Anterior Humeral Line should intersect the middle of the capitellum on x-ray; misalignment indicates possible fracture.
Summary Points
- Salter Harris Classification is critical for diagnosing pediatric fractures involving growth plates.
- Common incomplete fractures in children include torus (buckle) and greenstick fractures.
