Orthopaedic fracture fixation apparatus
A bone pin clamp for external fracture fixation apparatus comprises rotation, slide and housing elements (240, 220, 210) nested one within the next, each such element being apertured to receive a pin (100) therethrough, and the rotation and slide elements respectively affording pin adjustment in azi...

| description | A bone pin clamp for external fracture fixation apparatus comprises rotation, slide and housing elements (240, 220, 210) nested one within the next, each such element being apertured to receive a pin (100) therethrough, and the rotation and slide elements respectively affording pin adjustment in azimuth and zenith, and in height, relative to the housing element, and a locking mechanism (60, 80, 170) including a common actuator member (60) operable simultaneously to lock the pin and rotation and slide elements in the housing element. In a preferred form the housing element serves as a cylinder with the slide element as a keyed piston therein, and the rotation element is a disc located between a screw (60) and annular thrust members (80, 170) engaged in the piston, the piston and disc being split respectively to lock by expansion and compaction under screw action towards the thrust members. |
