Hip dislocation occurs when the head of the thigh bone is forced out of the pelvic socket. Hip dislocation usually occurs as a result of injuries, such as a car accident or a fall from a significant height. Hip dislocation is a serious medical emergency that requires immediate treatment.
Hip straining or tearing occurs when the muscles or tendons supporting the hip joint are torn or stretched beyond their limit. Strains may be mild, moderate, or severe, and can affect muscles, tendons or both.
