The metaphyses (singular: metaphysis) are the wide portions of long bones and the regions of the bone where growth occurs. Growth occurs at the section of the metaphysis that is adjacent to the growth plate (physis).

The metaphysis is located between the diaphysis and epiphysis.

A relatively rich blood supply and increased vascular stasis makes the metaphysis prone to haematogenous spread of infection in childhood and osteomyelitis.
