Simple, cheap and often the best technique for the repair of long bones. I/M pinning does not resist compression and rotation very effectively. It may be helpful to add an external fixator for two weeks if in any doubt. Smooth pins are most likely to migrate.The threaded pins are negatively cut and do reduce backing out particularly if the distal fragment is small. Our trochar tips are designed to cut bone but care must be exercised to avoid heat necrosis during insertion. Can be cut in half to produce cheap ESF pins. Steinman Intra-Medullary Pins

Threaded Pins & Wires Threaded wires have a much greater pull out resistance than smooth wires.They are very easy to insert using standard drills fitted with Jacobs chucks or wire drivers.Although having only trochar tips they will self tap in all but the hardest of cortical bone. Driven across fragments, threaded wires act as mini position screws which can be cut off flush to the bone surface or buried. It may be possible to place several threaded wires at angles to each other in a relatively small area. Available in coarse or fine thread pitches. Use the coarse in cancellous or metaphyseal bone.

CoarseThreaded Small Fragment Pins

Use threaded pins where you might use a 2mm fixation screw or K Wire, e.g. tibial crest transplant. Drive in with slow speed drill. Relatively coarse threads. 0.8mm thread pitch.

Use singly to re-attach small bone fragments. Use in multiples to re-attach larger fragments e.g. humeral condyles. (4 x 2.0 threaded pins have similar properties to one 3.5 screw while interfering less with the healing process). Use threaded washer to create screw effect.Very easy to insert using an orthopaedic drill. Thread pitch is 0.4mm for use in cortical bone. Self drilling. Cut off excess pin. For maximum pull out resistance drill through trans cortex and cut off trochar cutting tip. FineThreaded Small Fragment Pins 2.0mm
