| Objective:By comparing the curative effect of external fixation via plintlet and internal fixation via opening reduction in the treatment of distal radius fracture, the prognosis function of wrist joint is analyzed.Methods:To select 52 patients with distal radius fracture from Affiliated Hospital of Shandong University of Traditional Chinese Medicine, among which include 26 patients treated with plintlet, 9 males and 17 females, whose ages range from 46 to 78 and the average age is about 64.31±8.31. Fracture classification(AO): type A 4 cases, type B 17 cases, type C5 cases. There are 9 left side while 17 right side.There are 26 cases in the internal fixation group which include 11 males and 15 females, whose ages range from 48 to 78 and the average age is 64.31±8.72. Fracture classification(AO): type A 3 cases, type B 13 cases, type C 10 cases.There are 11 left while 15 right side. By comparing and analyzing the postoperative follow-up review X-Ray evaluation of radial height, radial inclination and radial incline of the two groups of patients, and the activities of flexion and extension, ulnar radial partial activities, rotation activities, grip strength, pinch strength and Gartland- Werley wrist joint function at the time of the final follow-up, fracture reduction and injured limb function are analyzed while the curative effect of the two groups are compared.Results:There is no obvious difference between two groups of patient’s general data such as age, sex, fracture type and the distribution of injured limb, which are comparable(P>0.05).The healing time for group treated with plintlet are 11.3±0.52 weeks, while 12.1±0.31 weeks for group treated with internal fixation, which appears to be no significant difference(P>0.05). There is no significant difference of postoperative X-Ray between two groups(P>0.05). After 12 weeks, the comparison of postoperative review X-Ray evaluation of two groups shows obvious difference(P<0.05): radial height(8.33±0.51)°,(10.62±0.34)°; radial inclination(17.98±1.41)°,(20.13±0.89)°; radial incline(6.46±1.12)°,(9.28±0.96)°, which indicates that the operating group turns out to be better than plintlet group in respect of recovery. At the time of the last follow-up, the wrist joint activity data of two groups of patients’ limb and the uninjured side are as follows: grip strength(87.42±3.36)%,(88.81±4.62)%; pinch strength(91.12±5.52),(90.72±5.47)%; the activities of flexion and extension(87.42±3.36)%,( 88.81±4.62)%; rotation activities(91.12±5.52)%,(90.72±5.47)%; radial-ulnar deviation(89.62±4.21)%,(90.82±3.31)%, which shows no statistical significant(P>0.05). The last follow-up Gartlang- werley functional scores of two groups of patients are as follows: patients in plintlet group are classified as excellent(7), good(14), fair(4) and poor(1), and the excellent rate is 80.7%; patients in internal fixation group are classified as excellent(9), good(13), fair(3) and poor(1), and the excellent rate is 84.6%, which shows no statistical significant(P>0.05).Conclusion:Our results show that small splints and nail plate fixation after X-Ray evaluation no significant difference, but healing after splint group X-Ray indicators vary widely, no significant changes in the internal fixation group, suggesting that the nail plate fixation stability than small splints, or apparent shift should be fixed within the nail plate fracture preferred type of unstable distal radius. Wrist function not statistically significant after treatment in two ways. |
