The effect of cerclage wires on the strength of diaphyseal bone
Injury, 1995In ten mature rabbits two cerclage wires were placed 9 mm apart on one femur. The contralateral femora were sham-operated and served as controls. The animals were killed after 99 days and the femora subjected to four-point bending tests. All wires were embedded in callus.

Forces Generated in Guide-Wires when Drilling Human Bone
Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 1995In orthopaedic surgery guide-wires are extensively used for the drilling of pilot holes in human bones to allow further drilling, reaming and screw-tapping to take place in the repair and reconstruction of fractures. The guide-wires are generally 1.5 to 2.5 mm in diameter and have a three-faceted point with or without a screw thread.

Effect of Cerclage Wires on Periosteal Bone in Growing Dogs
Veterinary Surgery, 1987Three diameters of wire were placed circumferentialiy around the femora of six 22 week old puppies. The wires were placed over the periosteum on one limb and under the periosteum on the other limb. The effect of the wires on actively growing bone was evaluated 3 and 8 weeks after placement. Diffuse growth of periosteal new bone occurred in immature dog

Acta Orthopaedica, 1993
Laboratory tests were carried out on cadaver animal bones to evaluate the thermal effect of inserting K-wires with a pneumatic hammer as compared to drilling. The mean maximum bone temperature 0.5 mm from the K-wires was 34 (22-72) degrees C using the hammer and 54 (19-100) degrees C for drilling, 1.0 mm from the K-wire the mean maximum temperature was

Journal of Biomechanical Engineering, 1993
The work shows correct procedures needed in order to gather reliable data from measurement of displacements versus axial load in a laboratory mounting of the Ilizarov external fixator. The mechanism of settling after load cycling is investigated. Detension under load is a major problem of wires.

Parametric study of bone drilling by the Kirschner wire
Medical Engineering & Physics, 2021In order to improve the quality and reduce mechanical damage during bone drilling in surgeries, the three key parameters in drilling by the Kirschner wire are experimentally studied based on the response surface method (RSM). And through response surface analysis, a predictive model of each factor and response value is established.

Experimental study of bone drilling by Kirschner wire
Medical Engineering & Physics, 2022Mechanical and thermal damage to the bone tissue during drilling process is inevitable and directly affects the postoperative recovery. According to clinical practices and present academic investigations, this study tries to reduce bone damage by experimental investigation of bone drilling by Kirschner wire considering the drilling force and ...

Tensile strength of wire-reinforced bone cement and twisted stainless-steel wire
The Journal of Bone & Joint Surgery, 1977To assess the tensile strength of wire-reinforced bone cement as used for posterior spine fusion, standardized bone-cement specimens reinforced with stainless steel and Vitallium wires 0.5 and one millimeter in diameter were tested in tension. The results showed that tensile strength of bone cement was increased significantly by reinforcing it with ...

Enhancement of Kirschner Wire for Bone Drilling
Volume 2: Processing, 2014This study advances design and manufacturing of the tip geometry of the Kirschner wire (K-wire) — a popular orthopedic drilling tool with a sharp, three-sided trocar point — for improved bone drilling efficiency. Since there is no active cutting edge as there is for twist drill bits, bone drilling forces can be so large as to cause excessive heat ...

The Thermal Effects of Kirschner Wire Fixation on Small Bones
Journal of Hand Surgery, 1999The aim of this study was to assess bone heating caused by the passage of fine (<2 mm) K-wires of different types. Stainless steel K-wires of trocar and diamond point configurations (0.8–2.0 mm) were drilled into the metatarsal bones from a freshly amputated lower limb at a constant force.
