A hamstring strain is an excessive stretch or tearing of hamstring muscles which are located at the back of the thigh. It is a common injury particularly seen in athletes who participate in sports activities that requires running, jumping, and kicking. During growth spurt the bones grow faster than the muscles. As a result, the muscle becomes tight and a sudden jump or stretch can tear the muscle away from its connection to the bone resulting in strain.
Iliotibial Band (ITB) Syndrome
Iliotibial band syndrome is an overuse injury resulting from the inflammation of iliotibial band. Iliotibial band is a tough group of fibers that begins at the iliac crest of hip and runs along the outside of the thigh, to get attached to the outer side of the shin bone just below the knee joint. Its function is to coordinate with the thigh muscles and provide stability the knee joint. Iliotibial band syndrome occurs when the iliotibial band and the lower outside portion of the thigh bone at the knee joint rub against each other. It commonly occurs in athletes, cyclists, and runners.
Periacetabular osteotomy is the surgical procedure indicated in hip dysplasia and it involves cutting the bone around the acetabulum so as to fit the head of the femur bone into acetabular socket. This method was developed and performed by Professor Reinhold Ganz and therefore it is also called as Ganz osteotomy.
