By providing components securable to anchor pins or screws of different diameters as well as providing clamps which hold associated pins in any position during adjustments, an external fixation or adjustable frame structure is provided which is capable of being quickly and easily assembled in any desired configuration. In the present invention, the frame structure is retained in any assembled configuration in order to allow final adjustments to be made, prior to the final securement of the frame assembly in the precisely desired configuration by closure of each clamp member. In this way, an entire frame assembly is capable of being constructed, adjusted, and readjusted in order to assure each component is oriented in the precisely desired position prior to final closure of the clamping members. In one preferred embodiment, the clamping members employed in the frame structure of the present invention incorporate friction pins internally mounted in each clamp which engages the rod member once this rod is inserted into the jaws of the clamp. In this way, any rod member inserted into the clamping jaws contacts the surface of the jaws and the friction pin, preventing the rod member from sliding or moving relative to the clamp. In addition, by incorporating a uniquely constructed, moving wedge plate that is adjustably engageable with any cooperating anchor pin, secure affixation of the mounting member with the anchor pins of any diameter is easily achieved, regardless of the orientation configuration, or diameter of the anchor pin.

Adjustable bone stabilizing frame system

An orthopaedic bone plate is coupled to a bone having an enlarged head at one end thereof which is attached to a shaft. The bone plate includes an elongate portion, a flared portion and an intermediate portion. The elongate portion is attachable to the bone shaft using a plurality of bone screws. The elongate portion generally defines a longitudinal axis. The flared portion is attachable to the bone head using at least one bone screw. The intermediate portion interconnects the elongate portion and the flared portion. The intermediate portion is structured and arranged to allow the elongate portion and the flared portion to move relative to each other in a direction transverse to the longitudinal axis when the elongate portion and the flared portion are attached to the bone.

Orthopaedic bone plate

A blade plate, as well as instruments and methods for securing the blade plate to a bone to reduce a bone fracture. The blade plate includes a plate portion and a blade portion extending at an angle relative to the plate portion. The plate portion includes a plurality of holes for receipt of bone screws for securing the blade plate to the bone about the bone fracture. A strut screw, inserted through a hole in the plate portion, spans the angle between the plate and blade portions, and threadingly engages a hole in the blade portion to slightly draw the plate and blade portions together to compress and support the bone fracture. A pair of top screws are inserted through holes in the plate portion at angles with respect to the strut screw on either side of the strut screw. Additionally, the blade plate is designed to closely conform to the surface of the bone to minimize the gap between the bone and the blade plate. In order to secure the blade plate to a bone, a chisel/drill guide, chisel, insertion guide, and screw drill guides are provided.
