Multifragmentary complete metaphyseal fracture
Definition
Multifragmentary complete metaphyseal fractures of the proximal humerus are classified as 11-M/3.2.
Further characteristics
Proximal humeral fractures are common in children. The proximal humeral physis contributes 80% of humeral growth and fractures in this area almost always heal and remodel. The remodeling potential decreases the closer the patient is to skeletal maturity.
Multifragmentary fractures often result from high-energy trauma and are usually displaced and unstable.
Some proximal humeral fractures occur after minor trauma due to an undiagnosed bone cyst in the humeral shaft.

X-ray
AP and lateral x-rays should be obtained.
Transthoracic views should be avoided.
