Patients with unilateral buttock depression may be caused by localized trauma, contracture of gluteal muscle, muscle dystrophy, etc. Patients can be relieved by general treatment, medication and surgery. 1. Localized trauma: when unilateral gluteal muscle is directly hit or impacted by trauma, it may lead to extensive damage to the gluteal muscle, resulting in localized depression. If there is no obvious discomfort, no treatment can be given. For patients whose appearance is affected, fat filling can be considered to improve the unilateral buttock depression. 2. Gluteal muscle spasm: For patients with hip depression caused by gluteal muscle spasm, normal activities and not affecting normal life, no special treatment can be carried out, and more massage and hot compresses can be done to deal with the problem, and exercise can be strengthened in normal times. If it affects the activities of hip joint, small needle can be used to loosen the adhesion of contracture, or minimally invasive surgery through arthroscopy. 3. Muscle malnutrition: For patients with hip muscle malnutrition caused by insufficient food, long-term bedridden or diabetes, etc., which leads to hip depression, they can be adjusted through exercise and dietary modification, improve unreasonable dietary habits, eat more beef, beef tendon and high-protein food, etc., carry out activities appropriately, and treat the primary disease actively. For patients who affect the aesthetics of the patient, can also be autologous fat filling, to improve the situation of buttock depression. It is recommended that patients try to choose regular hospitals for surgical treatment, pay attention to post-operative care, and do a good job of monitoring the condition, such as the emergence of adverse reactions can be timely medical treatment.
