These are used in surgery to aid in repairing the process of a fractured bone. In forefoot elective surgeries, these pins are mostly used for fixation of the phalangeal or metatarsal area.

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

Methods: The pedicle screw pilot holes were drilled within the center of the pedicle and the lateral and medial pedicle walls were violated in 9 human dried thoracic vertebrae. Kirschner wires or spiral wires were separately placed in the holes, and then the posteroanterior and lateral radiographs were taken. The radiographs were evaluated by 3 experienced spine surgeons and 3 young orthopedists. After radiographs were shown to these observers, they combined the posteroanterior and lateral radiographs in each place and determined whether the pedicle screw pilot hole violated the pedicle cortex or not. The results were analyzed by a statistical software. Results: Sensitivity, specificity and accuracy of the method using spiral wires to detect pedicle pilot hole placement were significantly higher than those of using Kirschner wires. With a true posteroanterior radiograph, the sensitivity, specificity and accuracy of the method using spiral wires approximated or attained 100%. Conclusions: The method of intrapedicular pilot hole placement verification using spiral wires is effective for guiding the accurate placement of pedicle screws.展开更多

Methods： This prospective study was conducted at the Department of Orthopaedic Surgery in Maharishi Markandeshwar Medical College from June 2005 to June 2010. Sixty-six children having closed fracture of the tibial shaft with a mean age of 7.7 years （range, 2-14 years） were recruited from emergency and outpatient department. They were treated with percutaneous intramedullary Kirschner wires. The clinical results of our study were rated on the basis of the criteria of union, nonunion, delayed union or malunion. All children were followed for one year. Results： Children achieved union in a mean time of 8 weeks （range, 6-10 weeks）. Postoperatively, three children （4.55%） had delayed union, one （1.52%） valgus deformity of lower leg, three （4.55%） post- operative knee pain and twelve （18.18%） skin irritation at pin site. Wires were removed after 8-22 weeks without any complications. No patient was lost to follow-up. The results were excellent in 95.45% and good in 4.55% children. Conclusion： This technique is cost-effective, simple, quick to perform, safe and reliable and avoids pro- longed hospitalization with good results.展开更多
