Hamstring Injuries (Tear/Rupture) Description

Hamstring Injuries (Tears/Ruptures)


One of the most common hip injuries is a hamstring tear or rupture.  It commonly occurs in kicking athletes, waterskiiers, or after accidents due to knee extension and hip flexion.


The hamstring tendons are normally injured through powerful eccentric contraction (the muscle tightening while it is lengthening).  This may occur during sprinting or hurdling, or else a fall with the leg extended (knee straight and thigh near the chest) – doing the ‘splits’.  The classical mechanism is a waterskiier who falls with the knee straight in front of their body.

Types of Hamstring Injuries

  • Pelvic bone avulsion: teenagers where the tendon is stronger than the bone, and the tendon pulls off part of the ischium (pelvic bone)
  • Sprains/Strains: where the tendon is intact, but the microfibers may be torn (“pulling a hammy”
  • Partial Tears: where the tendon/muscle has been partially torn, and some of it is still intact
  • Complete Tears: where the tendon has completely torn and the two ends do not meet, the two ends of the tendon may be pulled apart (retraction)

Acute Symptoms

Symptoms of an acute hamstring tear typically involve acute pain, swelling, difficulty walking and discomfort.  Sometimes there may be an audible ‘pop’, and the patient may grasp the buttock – the ‘clutch’ sign.  Pain is typically felt in the buttock and travels down the leg, it is worse with sitting and patients may find it difficult to drive or be seated for prolong periods.  Patients may complain of numbness or pins and needles in the back of the leg or foot, as the sciatic nerve can be frequently irritated by the tendon and haematoma (bruising).  Bruising from a hamstring rupture can be extensive, and extend from the buttock down the back of the thigh past the knee.

Chronic Symptoms

Patients who have chronic hamstring tears may be completely asymptomatic (have no problems) or have significant difficulties.  Problems such as
