Content
As further shown in FIGS. 2B and 2C, the first screw thread 240 and the second screw thread 242 may each have a substantially constant major diameter and pitch. Where it is present, the second screw thread 242 may be spaced such that its threads bisect the space between adjacent threads of the first screw thread 240. In some embodiments, the first screw thread 240 and the second screw thread 242 may have tapered minor diameter 250 that is smaller at the intermediate portion 202 than near the head 210. This tapered minor diameter may compress the cortical portion of the bone 102 for maximum purchase in the cortical bone as the screw 104 is inserted. The first screw thread 240, distally of the second screw thread 242, may have a constant minor diameter 252 that preserves and reduces stress on the cancellous portion of the bone 102.
