Imaging diagnosis and prognostication of hamstring injuries.

Abstract

Hamstring injuries are common in sports. Although management and outcomes are sport specific, clinical evaluation alone is a poor guide for treatment planning and prognostication. Cross-sectional imaging has added value in these cases. Specifically, the location (tendon attachment, classic or intramuscular myotendinous junction, or extramuscular portion of the tendon), specific muscles involved, and anatomic extent are factors that can influence the immediate treatment, expected convalescent period, and risk of recurrence in these athletes.
