The 5p signs of osteo-fascial compartment syndrome are the five clinical features of osteo-fascial syndrome: first, the patient’s limb becomes painless; second, the skin of the patient’s limb becomes pale or marbled; third, the patient’s limb has abnormal sensation or even loss of sensation; fourth, the patient’s limb is particularly prone to paralysis; fifth, the patient’s distal limb Fifth, the distal part of the patient’s limb will have no pulse when touched. The main manifestation of this disease is the obvious swelling of the limb and the occlusion of the blood vessels due to the increased pressure, which leads to the absence of a pulse in the distal part of the limb. When this condition occurs, it is recommended that the patient immediately go to the hospital for an examination and receive treatment from the doctor in order to promote physical healing and keep away from the disease.
