Thigh muscle atrophy caused by trauma for one year, if it is caused by long-term bedridden muscle wasting atrophy, generally able to recover; if the trauma caused by lower limb nerve damage caused by muscle atrophy, it is generally difficult to recover. If it is relatively minor trauma, no damage to tendons, ligaments and other parts of the body, and there is no serious tear or fracture, etc., after braking long-term bedridden, resulting in muscle wasting atrophy, rehabilitation, active local muscle rehabilitation exercise, in general, can be recovered. If it is a more serious trauma, a tear or fracture, etc., may lead to muscle atrophy caused by nerve damage in the lower limbs, it is generally very difficult to recover to the original state, may affect the normal life as well as normal physiological function. Thigh muscle atrophy should be timely to the hospital, improve the relevant examination, clear cause of the treatment and exercise as prescribed by the doctor, so as not to delay the condition.
