Distraction pin for fracture fixation

A fracture fixation pin system, comprising:

• a) a pin including
• i) a first portion having a first diameter and first threads of a first thread diameter, said first portion having a tip at one end and a second end,
• ii) a second portion coupled to said second end of said first portion, said second portion having a second diameter larger than said first diameter, and second threads of a second thread diameter larger than said first thread diameter, said first and second threads being continuous with each other and having a common pitch and thread depth, and
• iii) a non-threaded shaft portion coupled to said second portion, said shaft portion having a cross-sectional dimension which does not exceed a dimension of said second diameter,
• said second portion adjacent said shaft portion defining a plurality of longitudinal spaced apart negative spaces;
• and
• b) a driver member including a socket having structure adapted to interfere with said negative spaces.

• ii) a second portion having a first end coupled to said second end of said first portion and a second free end, said second portion having a second diameter larger than said first diameter, and second threads of a second thread diameter larger than said first thread diameter, said first and second threads being continuous with each other and having a common pitch and thread depth, wherein said second free end is provided with a plurality longitudinal grooves spaced-apart about a circumference of said second portion;
• and
• b) a driver member including a socket having structure adapted to interfere with said grooves on said second portion of said pin.
