Abstract: A novel radiation-protective neck support which provides cervical support and radiation protection for the neck and thyroid of a user, said support comprises (i) a soft collar portion which comprises a soft, flexible supportive material structure and is “leaded”, and (ii) a thyroid shield portion which descends from the soft collar portion and is “leaded”. The thyroid shield portion can descend as a “flap” from the soft collar portion or it can attach in other ways to achieve the protection desired for the thyroid. During surgery, the radiation-protective neck support is worn by a user, with the soft collar portion surrounding the neck of the user, thereby providing anatomical support and also providing radiation protection for the neck. With the thyroid shield portion descending as a “flap” from the soft collar portion, it will overlay the thyroid of the user and thereby provide radiation protection for the thyroid.

Abstract: A surgical implant system comprising: a spiked washer for impacting against the proximal end of a bone so as to achieve fixed positioning relative to the proximal end of the bone and an intramedullary screw for advancement through the washer and down the intramedullary canal of a bone. The intramedullary screw comprises a shaft and a head, distal threads formed on the shaft for engaging the wall of the intramedullary canal at the distal end of the intramedullary screw and proximal threads formed on the shaft for engaging the wall of the intramedullary canal at the proximal end of the intramedullary screw so as to generate a compressive force therebetween. The head comprises locking threads for engaging the screw threads formed in the spiked washer, whereby to lock the intramedullary screw to the spiked washer.
