Treatment of Pediatric Supracondylar Humeral Fractures With Novel Kirschner Wire Fixation Devices

Treatment of Pediatric Supracondylar Humeral Fractures With Novel Kirschner Wire Fixation Devices: A Prospective Comparative Study

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.

Detailed 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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Radiographs measurement
Time Frame: through study completion, an average of 1 year
Baumann angle and the location of anterior humeral line on the radiographs
through study completion, an average of 1 year
Elbow range of motion
Time Frame: through study completion, an average of 1 year
Elbow flexion an extension angle
through study completion, an average of 1 year
Pin sites condition
Time Frame: 4 weeks
The pin sites were inspected and graded according to the system of Dahl. Grade 0 was normal skin, grade 1 was pain or erythema without discharge, grade 2 was serous discharge, grade 3 was purulent discharge, grade 4 was radiographic osteolysis and grade 5 was ring sequestrum or osteomyelitis.
