Résumé
Severe limb trauma is one of the mostcommon orthopaedic emergencies,andthe choice betweenamputation andlimb salvage always plagues the clinicians who regardbody function recovery as their highest pursuit.Medical experts at home and abroad have continuously explored standards of amputa-tion or limb salvage,but each kind of scoring system has its own limitation in clinical decision.With the development of wound repair technology and microsurgical technology,clinicians have new understandings of the treatment about these diseases.This paperintegrates related clinical reports in recent yearsand analy-zes the key points of amputation or limb salvage for severe limb trauma,such as large defects of soft tis-sues,main arterial injury,and terminal osteofascial compartment syndrome.It may improve theunderstand-ingsfor these diseases and help clinicians choose more reasonable treatment plans.
