AbstractAn instrument for treating injuries and diseases of bones and joints which incorporates rings with needles passed through bone fragments. Adjacent rings are interconnected by longitudinal permanently sprung members, viz. helical springs and/or rods connected with the rings by means of nuts. To stabilize the structure, strengthening rings composed of separate arches and carrying locking means for additional needles may be inserted into the instrument.
