Abstract

An implant comprised a specially adapted bone screw having a threaded shank portion and a sleeve which mates with and operates in cooperation with the threaded shank portion is used with a driver specially adapted for inserting and removing the implant. The implant (20) generates bone compression by itself and can be used either alone or with plates and washers. It is easily inserted into a fracture and also is easily removed from the fracture. The driver comprises an inner rod (64) having a first driver means (82) positioned at the distal rod end. An outer cylindrical portion has a further cylindrical portion (72) integrally attached to its proximal cylindrical end and has a second driver means (78) positioned at its distal cylindrical end (76); locking means (66, 68, 70) lock the proximal rod end and proximal cylindrical end with respect to each other in a fixed position as desired but allow the outer cylindrical portion (74) to move with respect to the inner rod (64) when locking means (66, 68, 70) is not locked.
