<p>An orthopedic fixation device (10) and method for fixation of fractures of the proximal end of the ulna comprising a first fixation member (12) having an enlarged head (16) and an elongated body (20) having a threaded aperture (22) formed in the mid-portion thereof and a threaded outer portion (24) and a second fixation member (14) comprising an elongated pin (26) or a threaded flexible body (26) having a smooth tapered tip (28) at one end thereof and a head (30) having a groove (32) formed on the outer surface thereof at the opposite end thereof, specifically configured to provide a three point fixation to enhance the compression between the fractured surfaces, and to improve the rigidity and compression of fracture fixation thereby improving bone healing. The fixation device reduces problems of inadequate fixation of bone fragments during the healing period that can lead to non-union or mal-union of the fractures bones, especially for fractures of the proximal end of the ulna. </p> |
