Title (EN) ORTHOPAEDIC FRACTURE FIXATION APPARATUS
(FR) APPAREIL ORTHOPEDIQUE
Abstract:
(EN) Orthopaedic fracture apparatus involving adjustable assemblies of rods (50) and coupling mechanisms (40) connected to different parts of a fractured bone whereby the bone can be manipulated to and stabilised in a desired configuration. The invention provides, for such apparatus, coupling mechanisms each including a pair of clamps (41, 42) which are independently operable, rigidly interconnected, and have guides (45) to secure rods and the like in mutually perpendicular directions whereby manipulation can be effected selectively in mutually perpendicular planes by loosening corresponding first clamps or second clamps of these couplings. The geometry of the remainder of the apparatus should be appropriate to this function. For this purpose one form of bone pin connection assembly clamps a set of pins (20) in a parallel coplanar array and has an orthogonal post (35) for a coupling mechanism (40) and another form of such connection assembly involves a curved plate conforming to a limb and with mutually perpendicular tubular projections from its convex surface, these projections serving as pin guide/clamp sleeves and coupling posts.
(FR) Appareil orthopedique pour les fractures comprenant des assemblages de tiges (50) reglables et des mecanismes d"accouplement (40) fixes a divers endroits d"un os fracture de maniere a pouvoir le manipuler et le stabiliser selon une configuration voulue. Un tel appareil est pourvu de mecanismes d"accouplement comprenant chacun une paire de pattes d"attache (41, 42) fonctionnant independamment, assujetties les unes aux autres de facon rigide, et possedant des guides (45) pour fixer les tiges les unes perpendiculairement aux autres, permettant d"effectuer une manipulation selective selon des plans mutuellement perpendiculaires en desserrant les premieres attaches ou les secondes attaches correspondantes de ces accouplements. La geometrie du reste de l"appareil devrait etre appropriee a cette fonction. A cet effet, une forme d"assemblage a broches consiste en une bride de fixation d"un ensemble de broches (20) coplanaires et paralleles et en un montant orthogonal (35) pour le mecanisme d"accouplement (40), et une autre forme d"assemblage comprend une plaque incurvee se conformant au membre, ayant des projections tubulaires perpendiculaires entre elles se projetant de sa surface convexe et servant de guide-broche/manchon de fixation et de montants d"accouplement.
