Abstract
An orthopedic plate for treating orthopedic peri-articular fractures and osteotomies, including a flat and curve edged blade for insertion into the spongy or cancellous bone to gain fixation, a side plate portion which includes a plurality of screw holes, the side plate portion fixing the plate to the bone when screws are inserted in the screw holes, and a worm gear mechanism which connects the blade and the side plate portion, and which allows for variable angles between the blade and the side plate portion to overcome problems associated with fracture and osteotomy orientation and rigid fixation in cancellous bone in the metaphyseal portion of long bones such as the shoulder, knee, ankle, and hip, and thus, greatly facilitate the proper fixation and alignment for peri-articular fractures.
