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 ...

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.

Why fine-wire fixators work: An analysis of pressure distribution at the wire–bone interface
Journal of Biomechanics, 2007Tensioned fine-wire external fixator systems have been used successfully for the treatment of fractures, mal-unions and for limb lengthening for many years. When used in metaphyseal bone, this type of fixator has a lower loosening rate than half-pin fixators.

Kirschner wire fixation of bone plates in craniotomies
The American Journal of Surgery, 1958Abstract Kirschner wire fixation of bone plates in craniotomies is a rather simple and time-saving method. Usually three wires, 0.8 mm. in size, suffice to produce stable fixation. The wire is drilled from the margin of the craniotomy into the bone plate, but it also can be driven in from the bone plate into the margin of the craniotomy.

Bone-metal bonding after kirschner wire studding
Archives of Orthopaedic and Traumatic Surgery, 1981A clinical case is reported on in which there were difficulties in removing Kirschner wires from the bone four years after arthrodeses of a shoulder. These could only be removed with great force. They displayed muff-like mantling with bone. The histological investigations revealed that the bone had deposited directly on the metal surface and that ...

Fixation of nasal bone grafts with interosseous wire: our technique
The Journal of Laryngology & Otology, 2010AbstractBackground:The use of interosseous wire to fix bone grafts is well known. Herein, we describe a technique for fixation of an iliac crest bone graft for nasal augmentation, using a stainless steel wire.Method:A hole in the cancellous part of the graft guides the wire exactly into a groove in the cortical part, preventing slippage and ensuring ...

Kirschner-wire fixation of small bones.
American journal of orthopedics (Belle Mead, N.J.), 2007A simple technique for Kirschner-wire placement in small bones is to place the wire over the to-be-pinned bones, push the wire out through the skin, and run the wire back across the bones.

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.

Posterior cervical fusion with methylmethacrylate, wire, and bone: Technical note
Surgical Neurology, 1994Surgical stabilization of non-neoplastic spinal lesions with methylmethacrylate and wire remains a controversial issue. In this report we offer a method of posterior cervical arthrodesis that combines using midline wire and acrylic with a lateral bony fusion. This construct allows for immediate as well as long-term stability.

Transfixion Wire Positioning Within the Bone
Journal of Pediatric Orthopaedics, 2006The greatest angle that can be formed by the crossing wires at the proximal tibia level without altering safe corridors approaches only 60 degrees. Consequently, the wires are positioned more in the coronal than the sagittal plane. Looking for an increase in sagittal bending stiffness, we evaluated different wire positioning within the proximal tibia ...
