Abstract: front page image
(EN)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.
(FR)Un dispositif de fixation orthopedique (10) et un procede d"immobilisation de fractures de l"extremite proximale du cubitus comprenant un premier organe de fixation (19) qui presente une tete elargie et un corps allonge ayant une ouverture filetee (22) formee dans sa partie mediane et une partie externe filetee (24) et un organe de fixation (14) comprenant une tige allongee (26) ou un corps flexible filete (26) ayant une pointe conique lisse (28) a son extremite et une tete (30) ayant une rainure (32) formee sur sa surface exterieure a son extremite opposee, ayant une configuration particuliere pour assurer une fixation en trois points de maniere a ameliorer la compression entre les surfaces fracturees, et pour ameliorer la rigidite et la compression de la fixation de la fracture, ameliorant ainsi la cicatrisation osseuse. Le dispositif de fixation reduit les problemes de la fixation inadequate de fragments osseux pendant la periode de cicatrisation, qui peuvent se traduire par une non-soudure ou une mauvaise soudure des os fractures, specialement pour des fractures de l"extremite proximale du cubitus.
