Patients with a broken foot should pay attention to elevating the affected limb, fixing the ankle joint, resting in the flat or healthy-side position when sleeping at night, etc., as follows: First, elevate the affected limb: when sleeping after a broken foot, try to use a quilt or pillow to elevate the affected limb higher than the plane of the heart. Through the night rest will speed up the venous return, so that the swelling symptoms as well as pain symptoms are significantly relieved, which is conducive to restoring local blood circulation and promoting the repair of the injury. Second, compression bandaging and fixation of the ankle joint: When the patient with a broken foot sleeps at night, it is best to use a brace or elastic bandage for compression bandaging and fixation to protect the ankle joint to avoid stimulation or compression of the injured part during sleep due to the posture, resulting in increased pain and swelling, which is not conducive to repair. Thirdly, rest in the flat or healthy side position: when the patient sleeps at night, he can rest in the flat or side position, but try to rest in the healthy side position, do not put the affected limb under the body, causing compression or venous return obstruction will affect the recovery.
