What's the difference between Precice nail and nail used in LON? I've read that Precice models come in three diameters: 8.5, 10.7 and 12.5 mm (0.33, 0.42, 0.50 inches) and three lenghts, so that may put on gain restrictions if they don't exactly fit in the bone.

What about LON nails? Are they specifically designed for the patient or also come in standard sizes?
