Abstract
A bone reduction and fixation device (1, 70) comprises an elongated biplanar plate along most of its length having an L-shaped profile defined by a first plate surface (3A, 4A) and one or more second plates (3B, 4B), in which the first and second plates comprise a plurality of countersunk holes (8) configured for receipt of bone-fixing screws (10). The biplanar plate comprises two biplanar L-shaped end sections (3, 4) defined by end parts of the first plate and second end plates, and a monoplanar central section (2) defined by a central part of the first plate, in which the central part of the first plate has a thickness greater than the end parts. The L-shaped end sections help guide bone fragments into correct alignment and hold the alignment while the surgeon adjusts one of or both of the fragments laterally and medially to reduce the fragments. The L-shaped profile of the plate also provides for greater bending and torsional stiffness, allowing the plate to have a reduced thickness.
