Abstract
The invention relates to an adjustable length fixation device having a head slidable along the shaft of the fixation device. The head is larger than the shaft and prevents further distal migration of the shaft and may preferably include an external surface for engaging bone to prevent proximal migration of the shaft. The head includes an engagement portion which may be deformed to securely engage the shaft to prevent removal of the head from the shaft. The invention also contemplates a method of insertion which includes inserting the shaft into the bone, sliding the head along the shaft and into engagement with the bone, securely engaging the head to the shaft, and severing the shaft proximal of the head to thereby form a fastener of the required length.
