The main reason is the thickening of the posterior margin of iliotibial tract or the anterior margin of gluteus maximus tendon. When the hip joint flexes, adducts and pronates, the thickened tissue slides back and forth in the greater trochanter, making a clicking sound. At the same time, you can see and feel a thick and tight fiber belt sliding across the big rotor. Passive exercise does not have this phenomenon, which is more common in young adults and mostly bilateral.
This sudden onset is often spontaneous and can develop to a serious degree step by step. However, there is generally no pain. If there is pain, it is usually the result of bursitis of the greater trochanter.
Thickening of the leading edge of iliotibial tract or gluteus maximus tendon is related to trauma or strain. After trauma or strain, the affected tissues are hyperemia, edema and aseptic inflammatory reaction, which leads to a series of pathological changes such as fibrous tissue hyperplasia.
Sometimes the enlarged upper edge of the greater trochanter hooks the posterior part of the iliotibial tract and makes a clicking sound; Sometimes hip fracture is caused by iliopsoas tendon sliding on iliopubic tubercle and/or anterior inferior iliac spine. Sometimes it is the friction between the lower edge of gluteus maximus and ischium when the hip joint flexes, which leads to snapping; Chondroma of the greater trochanter can also cause snapping hip.
Hip varus is common in patients with snapping hip. Because the femoral neck shaft angle becomes smaller, the muscle arms of gluteus medius and gluteus minimus become shorter, and the abduction function is affected, which will increase the tension of the upper part of iliotibial tract and cause snapping and dysfunction.
Extended data
Excessive exercise harms the body in five forms.
1, heart rate change
Sports physiology research has found that athletes who are engaged in endurance events for life have a high probability of myocardial fibrosis, especially the hardening of heart cells. This sclerosis will lead to cardiac arrest, leading to arrhythmia. Runners who run more than 25 miles (about 40 kilometers) a week have the same risk of death as those who don't exercise.
2. Musculoskeletal changes
During exercise, muscles and bones will inevitably be damaged, and it takes 24-48 hours of rest to fully recover. If the muscle fatigue exceeds 48 hours, it means that the physiological function of the exerciser has been excessively challenged, and it also means that his muscle and energy storage have not been effectively restored. Researchers at Johns Hopkins University School of Medicine believe that chronic fatigue after exercise indicates that athletes overtraining.
3. Changes in the immune system
Excessive exercise impairs the function of the immune system, because the body needs to fight fatigue and insufficient muscle recovery. Research shows that high-intensity endurance exercise for more than 90 minutes makes athletes prone to get sick within 72 hours after exercise, because strenuous exercise temporarily reduces the function of immune system.
4. Hormone changes
Overtraining will affect the secretion function of hormones. Athletes will experience an increase in the secretion of cortisol and adrenaline (also known as stress hormones), which will increase blood pressure and cholesterol levels, thus inhibiting the function of the immune system. Overtraining can also suppress appetite by increasing the secretion of two hormones-adrenaline and norepinephrine. Insufficient calorie intake will slow down the recovery speed and make the discomfort of overtraining more serious.
5. Sleep changes
Excessive exercise brings stress to the body, leading to an increase in cortisol content. The increase of hormones such as cortisol will affect sleep habits. The role of cortisol determines the sleep mode, so if the cortisol content rises excessively before going to bed, it will hinder the quality of sleep.
