LOW PROFILE MEDICAL LOCKING PLATE AND BONE SCREW DESIGN FOR BONE FRACTURES

摘要

Disclosed embodiments of a low profile bone plate can allow for a locking relationship between the bone plate and one or more bone screws, without requiring specialized bone screws. According to the disclosure, a locking element and/or a flange can be provided in one or more through-holes in the bone plate to engage with the threads of the bone screw, to lock the screw in place. Locking elements, such as a straight wire or spring coil positioned near the bone-contacting surface of the bone plate can have a cross sectional diameter less than the pitch of the bone screw threads, so as not to interfere with insertion and tightening of the bone screw. Thus, standard bone screws without threaded heads or tapered shafts can be locked with a bone plate having a minimal thickness, which can advantageously improve chances of wound healing.
