The Comparative Study Of The Treatment To The Distal Radius Fractures Between Extenral Fixation And Small Splints

Objective: Comparative analysis of external fixation stents and small splint fixationtreatment curative effect in treatment of distal radius fractures.Methods: This topic research cases from the Affiliated Hospital of ShandongUniversity of Traditional Chinese Medicine orthopedic ward, and outpatientservices.Follow-up period from March2012to October2013,Subjects were50patientsaged above40years old (40~85years old) patients with fractures of the distalradius.Through single blind, randomized, controlled method,50patients with fracture ofdistal radius according to the different treatment methods are divided into external fixatorgroup (25cases), small splint group (25cases).According to the fracture type AO typeexternal fixator group: A2type (8cases),type A3(12cases), type C1(1cases), type C2(4cases), small splint group: A2type (8cases), type A3(9cases), type C1(4cases), type C2(4cases).Follow up all patients after treatment, change records measured at admission,after2days,2weeks after surgery, after4weeks,8weeks after the operation,palmar tilt, ulnardeviation and radial length in different period, and check the patients in each group after8weeks of wrist dorsiflexion, function, radial deviation, wrist flexion ulnar deviation,pronation and supination recovery.Evaluation of the effect of treatment in the two groupsby comprehensive evaluation of palmar tilt, radial ulnar deviation, high standard imaging,using Gartland-Werley wrist function score system of wrist joint function of two casesrecovered to score.Results: No significant differences in the two groups were age, gender, fracture type,and other random factors before treatment,Through this study, after8weeks inradiographic measurements of external fixator group:10.96±1.06palmar angle (°), ulnardeviation of20.20±1.41(°),the radial height of11.16±1.25(mm);After8weeks of imaging measurement of small splint group:9.84±0.80palmar angle (°), ulnar deviationof18.76±1.20(°), the radial height of8.76±1.83(mm).Comparison shows that externalfixator in palmar tilt group is better than small splint group recovery (p <0.05), in theaspect of ulnar deviation external fixator group is better than small splint group recovery (p<0.05), in terms of radial height external fixator group is better than small splint grouprecovery (p <0.05).Comprehensive evaluation of two groups of patients with palmar tilt,radial ulnar inclination, radial height, external fixation group was excellent in16cases,good in9cases, the excellent and good rate was100%,3cases of small splint group ofexcellent, good in18cases,4cases, the excellent and good rate was84%;Gartland-Werleywrist function score, external fixation group was excellent in10cases, good in13cases,2cases, the excellent and good rate was92%,6cases of small splint group of excellent,good in10cases,9cases, the excellent and good rate was64%, adverse reactions andcomplications were not found in two groups of patients during treatment.Conclusions: In this study, patients treated with A2, A3, C1, C2type of distal radiusfractures,external fixator, the image evaluation function better than the small splintfixation,more suitable for reposition and fixation of the fracture of the distal radius. Thetotal score display, external fixation is better than the small splint for the treatment offractures of the distal radius, is worthy of clinical application.
