✦ Precision Small Bone Fixation

K-Wire / Tension Band Wiring

Q: When are K-wires removed after fixation?

K-wires are typically removed at 3–6 weeks once sufficient healing is confirmed on X-ray. Removal is performed under local anaesthesia as a brief outpatient procedure and is usually straightforward, leaving only small healed entry point scars.

Q: Are K-wires as mechanically strong as plates and screws?

K-wires provide less rigid fixation than plate-and-screw constructs. They are chosen when fracture geometry, bone size, or the need for minimal tissue disruption makes rigid fixation unnecessary or inappropriate — particularly in small bones and paediatric patients.

Q: What distinguishes K-wire fixation from tension band wiring?

K-wires alone hold fragments by crossing the fracture. Tension band wiring adds a wire loop around the K-wires to convert distracting muscle forces into compression forces at the fracture — which actively promotes healing and is essential for olecranon and patella fractures.

Q: What is the infection risk with percutaneous K-wires?

Superficial pin tract infection can occur when wire ends are left outside the skin. Regular cleaning and keeping the area dry significantly reduce this risk. Deep infection is uncommon but requires prompt treatment and may necessitate early wire removal.

Thin surgical wires inserted through the skin hold displaced bone fragments in their correct position while healing occurs — a minimally invasive technique for fractures of the hand, wrist, kneecap, and elbow.

What is K-Wire / Tension Band Wiring?

Kirschner wires — universally called K-wires — are smooth stainless steel pins that are drilled across a fracture to hold its fragments together. They are frequently inserted percutaneously through the skin without a formal surgical incision, leaving only small entry wounds. Tension band wiring adds a wire loop threaded around the K-wires that converts the distracting pull of muscles crossing the fracture into a compressive force at the fracture site — making it particularly powerful for avulsion fractures of the patella and olecranon. Dr. Sai Kishan uses K-wire and tension band fixation at Lux Hospitals for a wide range of small bone and specific periarticular fracture patterns.

Used for displaced fractures of the fingers, hand, wrist — including distal radius and carpal bones — patella, olecranon, clavicle, and in selected paediatric fractures where physeal-sparing temporary fixation is needed and larger implant systems would be inappropriate.

How the Procedure Works

Anaesthesia Selection

Local anaesthesia with sedation, regional block, or general anaesthesia is chosen based on fracture location, patient age, and expected procedure complexity.

Fracture Reduction

The fracture is reduced using closed manipulation or a small incision; satisfactory position is confirmed under live fluoroscopy.

K-Wire Insertion Under Fluoroscopy

One or more K-wires are drilled across the fracture under X-ray guidance, securing the fragments in the reduced position.

Tension Band Loop Application (where indicated)

A wire loop is threaded through a drill hole and around the K-wires to convert distracting forces into fracture site compression.

Wire Trimming & Immobilisation

Wire ends are trimmed and bent or left percutaneous; a cast or splint protects the reduction until wires are removed at fracture healing.

Who Needs This Treatment?

→Percutaneous insertion avoids a large surgical incision over the fracture site
→Versatile across multiple anatomical sites — hand, wrist, elbow, kneecap, clavicle
→Tension band converts muscle pull from a distracting force into compression at the fracture
→Simple, efficient, and cost-effective compared to more complex implant systems
→K-wires are removed easily under local anaesthesia once fracture healing is confirmed
→Physeal-sparing fixation possible in children — avoids damaging growth plates

K-wires are one of the most versatile tools in a trauma surgeon's repertoire — simple, effective, and remarkably precise. Sometimes the most elegant solution is a couple of thin wires placed in exactly the right place.
