Two part external bone-setting apparatus - has non rigid coupling to one portion of broken bone with fixing pins

摘要

The external bone-setting apparatus (10) has a rectangular section (12) in first and second parts (14,16) defining a lengthwise axis (18). A pair of shafts (28) joined to the first part engage rigidly with the first portion (24) of the broken bone (22) under the action of a non-rigid coupling (42), to allow relative movement between the shafts and the first part. A second shaft group (30) secures the second part to the second portion (26) of the bone. ADVANTAGE - Avoidance of undesirable friction.
