the effect of wire plane tilt and olive wires on Proximal Tibia Fracture fragment stability and Fracture site motion
Journal of Biomechanics, 2005Co-Authors: Michael J. Voor, Valentin Antoci, Craig S. RobertsAbstract:To analyze the effect of the tilt angle relationship between the crossed wire plane and the bone axis on the stiffness of fine wire external fixation, load-deformation behavior was compared across different tilt angles (0°, 10°, and 20°) of the plane containing crossed smooth or olive wires under identical conditions of central axial compression, medial compression-bending, posterior compression-bending, posteromedial compression-bending, and torsion. Stiffness values were calculated from the load-deformation and torque-angle curves. A tilt angle of 20° with olive wires provided significantly greater stiffness compared to smooth wires at any angle in any loading condition (p<0.05). A tilt angle of 20° with olive wires was also significantly more stiff than a tilt angle of 0° with olive wires in any loading condition. In torsion, olive wires with 10° and 20° tilt were not significantly different, while in posterior bending olive wires with 10° tilt were significantly stiffer than olive wires with 0° or 20° tilt. With smooth wires, tilting the wire plane caused a decrease in stiffness in posterior bending, posteromedial bending, and torsion. Overall, the use of olive wires in conjunction with tilting the wire plane enhances the fixation stiffness for Proximal Tibia Fractures while allowing more options for wire configurations that avoid neurovascular and musculotendinous structures, and wounds.

OUTCOME AFTER Proximal TibiaL Fracture SUSTAINED DURING ALPINE SKIING
2018Co-Authors: R. Paetzold, Ulrich J. Spiegl, M. Wurster, Peter Augat, P. Gutsfeld, Oliver Gonschorek, Volker BuehrenAbstract:Alpine ski sports changed rapidly in the last decade. Complex Fractures of the Proximal Tibia, typically seen in high energy trauma, has been seen more frequently and more often related to alpine skiing.The aim of our study was to identify reasons for Proximal Tibia Fracture in alpine skiing and observe the outcome.All patients with Proximal Tibia Fractures related to alpine skiing, which were treated in our two trauma centers were included. The patients received a questionnaire at the emergency department, dealing with accident details and the skiing habits. The Fractures were classified according to the AO Fracture classification scheme. The follow up was performed at least one year after trauma with the Lysholm, the Tegner activity, as well as the WOMAC VAS Score.Between 2007 and 2010 a total of 188 patients with Proximal Tibia Fractures caused by alpine skiing were treated. 43 patients had a type A, 96 patients a type B and 49 a type C injury. The incidence was increasing over the period continuously....

OUTCOME AFTER Proximal TibiaL Fracture SUSTAINED DURING ALPINE SKIING

The incidence was increasing over the period continuously. The main trauma mechanism was an accident without a third party involvement with an increased rotational and axial compression impact. All outcome scores were related to Fracture severity with significant worse results for the type C Fractures. In conclusion, Proximal Tibia Fractures are an increasing and serious injury during alpine skiing. Further technical progress in skiing material should focus on these knee injuries in future.

nonoperative treatment of a pathologic Proximal Tibia Fracture in the setting of previous total knee arthroplasty a case report
Journal of Bone and Joint Surgery American Volume, 2020Co-Authors: Christopher N Carender, Malynda S Wynn, Jesse E Otero, Benjamin J Miller, Timothy S BrownAbstract:CASE We present the case of a super obese 51-year-old woman with a pathologic Fracture of the Proximal Tibia in the setting of a previous total knee arthroplasty. Imaging demonstrated an osteolytic lesion distal to the keel and pathologic Fracture of the Proximal Tibia. Nonoperative treatment with a 12-week course of nonweight-bearing resulted in Fracture healing and ossification of osteolysis. CONCLUSION Pathologic Fractures of the Tibia secondary to osteolysis are frequently treated surgically. Patients may benefit from nonoperative management, even in the setting of super morbid obesity and significant osteolysis about the Tibial component.
