A low-profile surgical rod implant device (10) is provided that allows the length of a rod spanning two bone screws to be adjusted at the time of implantation. In a separate aspect of the invention, the rod implant device can be secured by tightening and securing an end (24) of the rod implant device at one of the bone screws (34). Embodiments are provided for use with polyaxial pedicle screws and substantially straight shank pedicle screws in spinal applications. In a separate aspect of the invention, a bone screw connector (114) having an interference type fit is also provided. A method for implanting the device is also provided.
L'invention porte sur un implant chirurgical de faible épaisseur permettant d'ajuster lors de l'implantation la longueur d'une tige reliant deux vis posées dans deux os. Dans une variante, l'implant peut être fixé par vissage et serrage d'une extrémité de l'implant à l'une des vis. Dans d'autres exécutions, on utilise des vis à pédicule polyaxiales et des vis à pédicule à tige droite pour des opérations spinales. Dans une variante particulière, on utilise un connecteur à vis à ajustement forcé. L'invention porte également sur le procédé d'implantation du dispositif.
