Hamstring (HS) muscle injuries are the most common injury in sports. They are
correlated to long rehabilitations and have a great tendency to recur. The HS
consist of the long head of the biceps femoris, semitendinosus, and
semimembranosus. The patient's clinical presentation depends on the
characteristics of the lesion, which may vary from strain to avulsions of the
proximal insertion. The most recognized risk factor is a previous injury.
Magnetic resonance imaging is the method of choice for the injury diagnosis and
classification. Many classification systems have been proposed; the current
classifications aim to describe the injury and correlate it to the prognosis. The
treatment is conservative, with the use of anti-inflammatory drugs in the acute
phase followed by a muscle rehabilitation program. Proximal avulsions have shown
better results with surgical repair. When the patient is pain free, shows
recovery of strength and muscle flexibility, and can perform the sport's
movements, he/she is able to return to play. Prevention programs based on
eccentric strengthening of the muscles have been indicated both to prevent the
initial injury as well as preventing recurrence.
