Current concepts in the diagnosis and treatment of spondylolysis in young athletes.

Spondylolysis is common among young athletes and should be suspected in any young athlete presenting with low back pain that persists for more than a few weeks. Diagnostic evaluation typically includes plain radiographs followed by more sensitive modalities, including single-photon emission CT, CT, or MRI. There is no consensus on the most appropriate protocol for diagnostic evaluation. Treatment usually consists of rest and/or bracing to allow healing to occur, followed by rehabilitation that includes core strengthening. More large-scale controlled studies need to be done in order to clarify the most effective diagnostic and therapeutic protocols.
