Flexible nail assembly for fractures of long bones

摘要

An implant assembly of flexible nail for fractures of long bones comprising a straight universal length flexible nail having 15 to 25% of elongation of nail and ultimate tensile strength of 600 to 800 Mega Pascal on testing, wherein flexible nail is having an identical pathfinder blunt conical tip at both ends. An optional proximal fixation device to be used in combination with flexible nails having peripherally spaced plural grooves and optional plural holes for interlocking screws wherein each groove is deep less than diameter of one of flexible nails. An end cap with plural holes to be used in combination with proximal fixation device to anchor cut hooked ends of flexible nails. A tool plier-knurler cum cutter temporarily applied when flexible nails are alone in use.

主权项

1. An orthopedic implant consisting of:
a straight single flexible nail, wherein said nail comprising: a universal length; a first free end consisting of a first pathfinder conical tip; a second free end consisting of a second pathfinder conical tip; and a shaft defining a long axis of said nail, wherein said shaft and said first free end and said second free end are capable of having a plurality of curvatures at a plurality of planes along said long axis, thereby allowing said nail to fix, reposition and maintain relation of fracture fragments at a plurality of contact points of fixation inside a medullary canal and wherein said nail has a structure of 15-25% elongation on tensile stress and an ultimate tensile strength of about 600-800 MPa.
