Abstract
Objective: To observe the clinical effect of using internal fixation with non-Kirschner modified wire tension band on patellar fracture. Methods: 52 cases of patellar fracture were operated according to the standard protocol designed for the study. Of the 52 cases, 24 were underwent internal fixation with traditional Kirschner wire tension band group (K group)and 28 were with non-Kirschner modified wire tension band group(NK group). The cost of hospitalization, operating time, loss of blood intraoperative and time of fracture healing, complications of loosening and breakage of internal fixation, and the pain on touching Kirschner wire and the functional evaluation using Bostman method at 2 weeks, and 1, 3, 6 and 12 months postoperation were compared. Results: In the K group, 4 cases showed loosening of internal fixation (17.4%), 1 breakage of internal fixation(4.3%) and 6 showed pain on touching Kirschner wire (26.1%), but none in the NK group showed any complications observed in the K group, and the differences were significant between the twos (P < 0.05). The cases showed excellent, good and poor were 11, 8 and 4 respectively and the rate of fineness was 82.6%based on Bostman evaluation in K group. However, the corresponding figures in the NK group were 18, 7, and 1, and 96.2%. Except at 2 weeks, all differences were statistically significant in the twos (P < 0.05). Eighteen cases(78.3%)asked to have their internal fixation devices removed in K group while 8 cases (30.8%) in NK group, which was statistically different (P < 0.05). Conclusion Comparing with the internal fixation with traditional Kirschner wire tension band, non-Kirschner modified wire tension band showed no increased medical cost,operating time, intraoperative blood loss and the time of fracture healing. Furthermore it showed, less complications,faster and better rehabilitation of joint functions.关键词
