Description:
Fingergelenksarthrodese
A biomechanical study was conducted to test the suitability of a new implant, the compression wire (Königsee Implantate, Allendorf, Germany), for proximal interphalangeal joint arthrodesis in comparison to intraosseous wiring. In a cross-over design arthrodesis by intraosseous wiring, a single oblique compression wire and two crossed compression wires was tested in flexion and extension bending to 10°. Additionally, in a parallel group design testing to failure in extension bending was performed with intraosseous wiring and a single oblique compression wire. Prior to testing the bone mineral density was measured by dual x-ray absorptiometry (DXA). All joints were fused at 20° flexion. Statistical evaluation showed statistically significant superiority of the compression wires in comparison to intraosseous wiring in flexion and extension bending to 10°, but showed no superiority when tested to failure in extension bending. Furthermore, no correlation between bone mineral density and biomechanical stability was found. Due to the test results the compression wire seems to be suitable for proximal interphalangeal joint arthrodesis and further clinical and biomechanical studies should be conducted in order to implement it as a new technique for proximal interphalangeal joint arthrodesis.
