Malposition might cause future metatarsalgia, mid-foot pain and discomfort, which may dictate an on-going need for in-shoe orthosis, shoe modification and, occasionally, operative correction. To minimize and prevent these problems, we describe a simple technique for reduction and fixation of metatarsal fractures by Kirschner wires. We have found this technique to be a simple and efficient way of reducing and fixing metatarsal fractures. It is applied easily by the closed and open technique.展开更多

Methods: a total of 30 patients with patella fracture treated in our hospital were collected from May 2018 to May 2021, and 15 patients were selected to be included in the observation group. The plan was as follows: the 15 patients in the control group were treated with kirschner wire tension band. The operation, time of fracture healing and hospitalization, excellent rate of postoperative knee joint recovery and complications in the two groups were analyzed. Results: compared with the control group, the statistical data of average fracture healing and average length of stay in the observation group showed a trend of shortening, the difference was P<0.05;there was no difference in operation time between the two groups (P>0.05). After the follow-up, the excellent rate of knee joint in the observation group was significantly better than that in the control group (P<0.05). There were no complications in the observation group and 3 cases (20.00%) in the control group, and the difference was not significant (P>0.05). Conclusion: by the needle was hollow tension screw internal fixation and tension band heal scheme analysis, the former for patellar fractures develop group, results obtained compared with the latter, the better, can speed up the patients postoperative fracture healing and the recovery of knee joint, and fewer complications, for the clinical treatment of patellar fracture disease to provide an effective reference.展开更多
