Treatment of Pediatric Supracondylar Humeral Fractures With Novel Kirschner Wire Fixation Devices
Summary
A novel K-wire external fixation device was developed by the investigators. The K-wires can be connected by the device. After connection, the structure of the K-wires is transformed to an external skeletal fixator. Therefore, the K-wires are stabilized and unable to migrate independently. The stability of fracture fixation is better in patient with this K-wire external fixation device.
The purposes of this study are to optimize the K-wire external fixation device and test its function in real clinical practice.
Description
Supracondylar humeral fractures are the most common elbow fractures in children. Closed reduction and internal fixation using percutaneous Kirschner wires (K-wires) are widely recommended for Gartland type II and III fractures. After percutaneous pinning, the K-wires are bent at the skin edge and cut. The cutoff point is about 1 cm outside of the skin.
The diameters of the K-wires are between 1.5-3.0 mm. The surface of the K-wire is smooth. Therefore, the K-wires are easy to rotation and migration. Proximal migration or rotation of a K-wire could injure the skin. Distal migration of a K-wire could result in loss of reduction and fixation. Therefore, stabilization of the K-wires is important.
A novel K-wire external fixation device was developed by the investigators. The K-wires can be connected by the device. After connection, the structure of the K-wires is transformed to an external skeletal fixator. Therefore, the K-wires are stabilized and unable to migrate independently. The stability of fracture fixation is better in patient with this K-wire external fixation device.
The investigators got a one-year grant from the Ministry of Science and Technology in Taiwan last year. The preliminary data revealed that the torque and torsional stiffness with the K-wire external fixation device was greater than traditional pinning.
The purposes of this study are to optimize the K-wire external fixation device and test its function in real clinical practice.

Medical and Biotech [MESH] Definitions
Fracture Fixation
The use of metallic devices inserted into or through bone to hold a fracture in a set position and alignment while it heals.
Bone Plates
Implantable fracture fixation devices attached to bone fragments with screws to bridge the fracture gap and shield the fracture site from stress as bone heals. (UMDNS, 1999)
Fracture Fixation, Internal
The use of internal devices (metal plates, nails, rods, etc.) to hold the position of a fracture in proper alignment.
Orthopedic Fixation Devices
Devices which are used in the treatment of orthopedic injuries and diseases.
Fracture Fixation, Intramedullary
The use of nails that are inserted into bone cavities in order to keep fractured bones together.
