The incision, which can be done at a 90 degree angle from the vulva towards the anus or at an angle from the posterior end of the vulva (medio-lateral episiotomy), is performed under local anesthetic (pudendal anesthesia), and is sutured closed after delivery.
Hamstring hyperextension can occur during exercise and stretching. The hamstrings are a group of muscles found at the back of the thigh. Three muscles are in this group: the biceps femoris, the semitendinosus and the semimembranosus. The function of these muscles is to bend the knee and to extend the hip. It is common for these muscles to become hyperextended and injured.
A hamstring tendon strain, also referred to as a pulled hamstring, is a common injury in sports that involve sprinting or jumping. The severity of the strain can be graded from 1 to 3, with 1 being a minor tear, grade 2 a larger tear, and grade 3 representing a total rupture of the muscle.ndividuals who have a grade 1 injury typically experience pain when walking and minimal swelling of the tendon. A grade 2 injury makes movement more difficult, and it may be unbearable to straighten the leg. People who have a grade 3 strain experience immediate swelling of the tendon and intense pain.
