Abstract:Objective To explore the clinical effect of titanium elastic intramedullary nail in the treatment of middle tibial traumatic fracture and its influence on postoperative rehabilitation.Methods A total of 91 children with middle tibial traumatic fracture were divided into two groups: traditional internal fixation group (45 cases, treated with open reduction and locking compression plate internal fixation) and elastic intramedullary nail group (46 cases, treated with titanium elastic intramedullary nail internal fixation). The differences of fracture recovery effect, therapeutic observation index, callus growth and safety index between the two groups were compared.Results The excellent and good rate of fracture repair, hospitalization time, fracture line disappearance time, intraoperative blood loss, bone healing time, and operation time in the elastic intramedullary nail group were shorter (or better) than those in the traditional internal fixation group (P < 0.05); The callus growth score of the internal nail group was higher than that of the traditional internal fixation group (P < 0.05); the change trend of the callus growth score of the traditional internal fixation group and the elastic intramedullary nail group was different (P < 0.05); The elastic intramedullary nail The incidence of adverse reactions and complications in the group (6.52%) was significantly lower than that of the traditional internal fixation group (22.22%) (P < 0.05).Conclusion Compared with the open reduction and locking compression plate internal fixation, titanium elastic intramedullary nail is more conducive to bone healing and callus growth.
