Periostitis and osteomyelitis in chronic drug addicts

Abstract
Periostitis and osteomyelitis can occur in drug addicts not only by hematogenous dissemination of the infecting organisms, but as a result of introduction of bacteria by direct injection into periosteum or injection through infected skin and subcutaneous tissues. A spectrum of examples of osteomyelitis of the bones of the forearm in drug addicts is presented to illustrate this phenomenon. Neglect of these infections and the trauma of continued injections can lead to extensive tissue and bone loss.
