Supracondylar Fracture
Lateral Epicondyle Fracture
Background
- Salter-Harris type IV Fx
- Neurovascular injury uncommon
Diagnosis
Clinical Findings
- Swelling and tenderness limited to lateral elbow
neurovascular injury is uncommon
Imaging
- Obtain oblique view if suspicion high despite neg AP/lat
- Radiocapitellar line won't intersect middle of capitellum in all views
- May be only sign of fracture if fracture is entirely through growth plate
- +Fat Pad Sign/"sail" sign
- May be only sign of nondisplaced fx
Treatment
- Often requires ORIF (ortho consult)
Medial Epicondyle Fracture
Background
- Not true Salter-Harris fx (apophysis, not physis, is involved)
- 50% assoc w/ elbow dislocation
Diagnosis
- Displacement of medial epicondyle ossification center
- May become entrapped w/in elbow joint
- Use CRITOE to determine if bone in joint is medial epicondyle or nl trochlear oss center
- If think is trochlear but cannot see medial epicondyle fragment is medial epicondyle
- (Medial epicondyle normally ossifies before the trochlea)
- If think is trochlear but cannot see medial epicondyle fragment is medial epicondyle
- Fat pad sign not usually present because most injuries are extra-articular
Treatment
- Ortho consult
Olecranon Fracture
Diagnosis
- Often occur in a/w fx of radial head/neck
Treatment
- If displaced <5 mm immobilize in stable position (usually 45 degrees of elbow flexion)
- ORIF indicated for unstable fracture
- Orthopedic consultation is best to guide treatment
Radial Head/Neck Fracture
Management
- Ortho consultation to guide treatment
- ORIF indicated when angulation >60 degrees or displacement >50%
