Gluteus contracture may be caused by the following types of reasons: first, because of vascular lesions, such as vascular stenosis, vascular spasm or vascular blockage, because when the blood vessels have these lesions, it can cause the blood flow in the blood vessels to decrease, thus unable to provide sufficient nutrients and growth factors to the gluteus muscle at the lesion site, which can also lead to the lack of trace elements in the gluteus muscle at the lesion site, such as calcium, iron, zinc and Second, it may be due to neuropathy, when the patient’s gluteal nerve is damaged, or the sciatic nerve, or its branches are impaired, the gluteal muscle is also unable to obtain sufficient nutrients, in addition, the lesioned nerve is also unable to make the gluteal muscle obtain sufficient movement, these factors can lead to contracture of the gluteal muscle.
