Abstract
The invention contemplates orthopedic external minifixation apparatus comprising two articulated members having two clamps, each of which is carried by a different one of the articulated members. The articulating connection between members includes provision for simple and rapid alignment of the articulation axis with the articulation axis of the joint between two bones to be treated, thereby permitting early functional re-education and reduction of healing time. In its preferred form, several embodiments are disclosed.
Claims17
An articulated external minifixator device, comprising two elongate arms with a single-axis articulating connection of adjacent ends of said arms, said connection being characterized by an alignment guide bore on the axis of articulation, first clamping means including spaced guideways adpated for clamping at least two orthopedic pins which are longitudinally spaced and oriented transverse to the direction of elongation of one of said arms, said first clamping means being at offset from the articulation axis, second clamping means including spaced guideways adapted for clamping at least two orthopedic pins which are longitudinally spaced and oriented transverse to the direction of elongation of the other of said arms, said second clamping means being at offset from the articulation axis, and means including a longitudinal lead screw in one of said arms and egaging the clamping means of said one arm for selective longitudinal positioning adjustment of the clamping means of said one arm.
