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.
