Abstract

A dynamic finger fixator (10) comprises a two-part elongate strut element (12) and two pin-engagable elements (14) spaced apart on the two-part elongate strut element (12). The two-part elongate strut element (12) includes spacing-adjustment means (16) for selectively adjusting and setting a spacing between the two pin-engagable elements (14). Preferably, a first said part of the strut element includes a strut member (20), and a second said part includes a rotatable adjuster (32) forming at least part of the spacing- adjustment means (16) rotatably mounted on the strut member (20). The strut member (20) includes a first said pin engagable element (14) and the rotatable adjuster (32) includes a second said pin engagable element (14, 34) which is off-centre on the rotatable adjuster (32), so that dynamic fixation is impartable to a patient's finger.
