5Determination of nail length

Nail length

If there is no radiographic ruler and/or image intensifier available, a simple, clinical, intraoperative length measurement is advised. With the intramedullary guide wire in proper position, place a second guide wire of equal length at the entry portal and measure the difference in length between the two wires (a). This difference represents the proper nail length (b), see illustration.
It is always advisable to double-check the measured length by comparison with the contralateral (intact) tibia.
