A muscle strain is an injury caused by tearing of the muscle fibres.
Hip strains are injuries to the muscles that surround your hip joint.
Your hip joint is made up of a ball and socket joint. The ball is called the femoral head and the socket is called the acetabulum. The acetabulum is part of your pelvis whilst the femoral head is part of your thigh bones.
Muscle strains frequently occur in the hip area when a stretched muscle is forced to contract suddenly. In athletes, the most common injuries of the hip and groin region are muscle strain injuries.
Muscles around the hip joint are especially prone to strains because of eccentric contraction, which causes tremendous forces in the muscle. Strains around the hip include groin pulls, hip flexor strains and hamstring strains.
The risk of muscle strain increases if you:
- have previously injured your hip muscles
- do not warm up properly before exercising
- attempt to do too much too quickly
Strains may be mild, moderate, or severe, depending on the extent of the injury.
