摘要The incidence of limb fracture is very high in patients with multiple injuries.In addition to limb fracture,some patients have traumatic brain injury as well.When severe traumatic brain injury is combined with limb fracture,the injury is often critical and complicated,with high mortality and poor prognosis.The final treatment outcomes of patients depend on injury evaluation and resuscitation,operation time,anesthesia mode,perioperative pain management,blood transfusion,nutrition and other perioperative issues.It is of great significance to master the correct evaluation method,choose the appropriate treatment strategy and reduce the risk of second-hit to the brain for the treatment of limb fracture complicated with traumatic brain injury.At present,there is no clinical guideline or expert consensus on the surgical treatment of limb fractures combined with traumatic brain injury.In view of this,the National Orthopaedic and Sports Rehabilitation Clinical Research Center launches the Expert Consensus on the Surgical Treatment of Limb Fractures combined with Craniocerebra Injury.Seven clinical problems that orthopaedic surgeons most concern about are selected,and relevant recommendations are finally formed,aiming at summarizing relevant treatment experience,guiding further clinical practice,and improving the treatment effect of limb fracture patients combined with traumatic brain injury.
