Hip flexor tendonitis, a.k.a: hip tendinopathy, or even more accurately, iliopsoas tendonitis is inflammation of any one of several tendons in the hip, generally associated with degeneration of the tendon. Because tendons tend to have poor circulation, these injuries are often slow to heal.
This week, we will begin a study of Hip flexor tendonitis. In Part 1, we will discuss common causes and symptoms, and risk factors for hip tendonitis.
The muscle involved with this condition is called the iliopsoas. The iliopsoas muscle flexes the hip, bends the trunk towards the thigh and rotates the thigh bone. It’s made up of two muscles -- the psoas and iliacus. These muscles run from the lower spine and pelvis, join together, and then attach by a tendon to the upper thigh. This tendon can get irritated from overuse, muscle weakness and muscle tightness, causing tenderness and pain.
The injury is not only associated with athletes. Ironically, it can also be caused by a simple lack of flexibility in the hip joint. Sitting for long periods of time, with the legs at 90° to the trunk, as is common with many modern jobs or the disabled, can cause a shortening and weakening of the muscle-tendon unit associated with the hip area.
People with iliopsoas tendonitis often complain of “clicking” in the hip and pain while running, walking or kicking. Even putting on socks can be painful!
Hip tendonitis occurs when the hip tendon is put under a lot of strain, either doing something that it is not used to, doing the activity more than normal or due to biomechanical problems
This condition can affect athletes who participate in sports like cycling, running, swimming, hockey and baseball. Spin classes, high-intensity interval training (HIIT) workouts and activities involving kicking, squatting and jumping are also associated with this type of injury.
Conversely, people who spend many hours in a sitting position can develop hip flexor tendonitis.
The first symptom of Hip tendonitis is a gradually increasing pain in the hip. The hip will be tender at a specific point from where the tendon originates and stretching the muscle involved may be uncomfortable. The hip may feel stiff in the mornings or after a long rest period. Often pain decreases with activity as the tendon warms up only to return worse later. Eventually it may interfere with daily movements such as climbing stairs, walking for long periods or running. The pain often causes the patient to develop a limp and may interfere with any physical activity
A combination of factors may contribute to the development of Hip tendonitis, these include:
Overuse. Athletes who participate in sports that put a lot of strain on the hip joint, like cycling, running, and baseball are at a high risk of developing this injury. Martial arts, high-intensity interval training (HIIT) workouts and activities involving kicking, squatting and jumping are also at risk for this type of injury.
Lack of physical activity. Today’s sedentary lifestyle, workplace and computer culture is causing more people to sit for longer periods of time than ever before. The result is that leg muscles shorten and the hip joint weakens. This leads to muscular imbalance.
Muscular imbalance. If some muscles in the legs are much stronger than other muscles, the stronger muscles could pull harder on the hip tendons. This uneven pull can cause tendonitis.
New or renewed physical activity. An abrupt change in the type or duration of physical activity can cause hip pain. This is often due to the fact that the body has adapted to its previous routines. It will take time to adapt to new ones.
