Two patients among four previous cases of isolated ulnar fractures were treated with cannulated compression screws, and one patient was treated by applying fixation with a Herbert screw
. The patient outcomes in the three cases were almost good or excellent.
is a percutaneous headless screw with two threaded sections of different pitches, which would automatically provide some compression.
Up-to-date surgical treatment of scaphoid fractures and nonunions requires incorporation of numerous innovations of the last ten years, including the headless Herbert screw
, the annulated headless screw, and improved techniques for vascularized bone grafts.
The fracture site was not exposed and a Herbert screw
(Zimmer, U.S.A.) was inserted to fix the fracture site of the scaphoid under fluoroscope.
In the light of our experience, we would recommend the use of a pre- bend K-wire is alternative to Herbert screw
because it takes lesser time to operate, cost effective and even moderately experience surgeon able to fixed without any complication in the management of type II fractures as it allows rigid fixation and as a consequence early mobilization but there is disadvantage of reoperation in which the plane of fracture is saggital in which the pre bend end is not completely embedded in bone.

The fragment was reduced and fixed with a Herbert screw
placed in the antero-posterior direction to achieve an inter fragmentary compression.
At 2000 cycles, the Acutrac samples displaced an average of 1.40 mm less than the Herbert screw
specimens; this was statistically significant (p < 0.02).
Saeden and associates (34) prospectively compared Herbert screw
fixation versus long-arm casting for stable waist fractures.
