ABSTRACT
Objective To analyze the reasons of the delayed healing factors after internal fixation of limb fracture and the prevention and treatment measures.Methods 220 cases who were treated with internal fixation of fracture cases were retrospectively analyzed,compared difference with patients with postoperative (observation group of 1 10 cases)and non delay healing patients (1 10 cases in the control group)related factors.Results In the obser-vation group,age (62.6 ±10.2)years old,43.6% with diseases in department of internal medicine,the loose of internal fixation ratio was 25.5%,external fixation improper proportion was 30.9%,functional exercise did not correct rate was 56.4%,higher than those of the control group (50.5 ±9.4)years old,11.8%,1.8%,7.3%,8.2%%(t=9.149 1,χ2 =27.786,26.091,58.416,19.893,all P0.05 ). Conclusion There are many factors in delayed healing after internal fixation of limb fracture,the patients age,associ-ated with diseases in department of internal medicine,the loose of internal fixation,external fixation and functional exercise is not correct are the main factor of the limbs fracture postoperative delayed healing,and should take meas-ures timely to guide firmly fixed and regular postoperative preoperative exercise and avoid postoperative delayed union and nonunion.
