Internal fixation with Kirschner wires is as efficient as rigid screw fixation in scaphoid fracture: long-term
Abstract:
This study aimed to compare the long-term efficacy of Kirschner wires and Herbert screw internal fixation in scaphoid fracture. A retrospective chart with radiographic review and functional follow-up was conducted for patients with the scaphoid fracture. 65 patients (40 for K-wire fixation and 25 for Herbert screw) were enrolled. The nonunion rate for K-wire fixation and screw method were indifferent comprehensively and for iliac graft subgroup. Less bone necrosis was found with K-wire fixation (2.5% vs 16%, P=0.049). There's no difference between groups in Mayo scores, post-operation pain and grid strength. Patients with K-wire fixation have larger range of motion on radial/ulnar deviation (35.25±11.32 vs 28.00±8.66, P=0.007). The results support the use of Kirschner wires in the treatment of scaphoid fractures. Advantages such as high union rates and good function recovery of wrist could be expected from minimal invasion, multi-axial stable fixation.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Self-Locking Screw
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.
