1. A method for accessing a treatment area in a bone via a device, wherein the device comprises (i) an elongated hollow shaft having a proximal end and a distal end, (ii) a first attachment mechanism coupled to the proximal end of the elongated hollow shaft, (iii) a rod having a proximal end and a distal end, wherein the rod is removably positioned at least partially within a lumen of the elongated hollow shaft, (iv) a second attachment mechanism coupled to the rod between the proximal end of the rod and the distal end of the rod, wherein the first attachment mechanism and the second attachment mechanism are configured to be removably coupled to one another, and (v) a cap configured to be removably coupled to the second attachment mechanism, the method comprising:
(i) removably coupling the first attachment mechanism to the second attachment mechanism;
(ii) inserting the distal end of the rod and the distal end of the elongated hollow shaft into the treatment area of the bone by (a) coupling a drill to the proximal end of the rod, and (b) rotating, via the drill, the rod until the distal end of the rod reaches the treatment area in the bone;
(iii) decoupling the first attachment mechanism from the second attachment mechanism;
(iv) removing the rod and the second attachment mechanism from the device;
(v) injecting a reabsorbable bio-material composition through the lumen of the elongated hollow shaft and into the treatment area in the bone; and
(vi) removing the elongated hollow shaft from the treatment area in the bone.
