| ObjectiveTo investigate the clinical effective of calcium phosphate cement(CPC)via percutaneous injection combined with splint external fixation in treating elder patients with distal radius fractures.MethodsThe subjects of this study were patients with distal radius fracture(AO type A2,A3,B3)who comed from Pan Yu Hospital of Chinese Medicine district from January 2017 to June 2018.Subjects meeting the inclusion criteria were randomly divided into the experimental group(injection type calcium phosphate artificial bone joint splint external fixation)and the control group(single splint external fixation).The two groups of patients were treated by the same group of doctors for manual reduction and fixation,in which the control group received external fixation with splints after manual reduction,and the experimental group received external fixation with injected calcium phosphate artificial bone through percutaneous puncture under the assistance of c-arm fluoroscopy,followed by external fixation with splints.The volar Angle,ulnar Angle,radius shortening length,PRWE score and splint fixation time were compared after 3 months.The data were analyzed by SPSS20.0 software(Chinese version).ResultsA total of 101 patients were included in this study,and were randomly divided into the experimental group with 52 patients and the control group with 49 patients.During the treatment,2 patients and 1 patient were shed,respectively.The demographic characteristics of the subjects in the experimental group and the control group,as well as the AO classification of fracture,were compared,and the baseline balance of the patients in the two groups(P>0.05).After the first reduction,both the treatment group and the control group obtained satisfactory palmar Angle and ulnar Angle.However,the palmar Angle and ulnar Angle of the treatment group and the control group were all lost to different degrees after three months of treatment.The palmar Angle and the ulnar Angle of the experimental group and the palmar Angle of the control group were compared before and after,(>0.05,the difference was not statistically significant,the ulnar Angle of the control group was compared before and after,P<0.05,the difference was statistically significant.Three months after the treatment of the experimental group and the control group,the length of the radius was shortened in different degrees,especially in the control group.Compared with the splint fixation group of the control group,the fixation time of the test group was relatively short,P<0.05,and the difference was statistically significant.The PRWE scores of wrist joint function in the experimental group and the control group were compared after 3 months of treatment,and the experimental group had a higher superior and superior rate in the short term.One case of artificial bone leakage event of calcium phosphate occurred during operation in the experimental group.ConclusionFor the treatment of senile distal radius fractures with injection of calcium phosphate combined with splint external fixation,fracture reduction can be effectively maintained,splint fixation time can be shortened,and PRWE score of wrist joint can be achieved in a short period.However,there is a risk of artificial bone leakage of calcium phosphate.Careful operation is required during the operation and to control the artificial viscosity of calcium phosphate.The results indicated that the injection of calcium phosphate combined with splint external fixation for the treatment of senile distal radius fracture has certain advantages compared with the traditional single splint external fixation,which is worthy of further clinical discussion and application. |
