Patent ID: 11432855

Abstract:
A compressive intramedullary rod includes first and second concentric shafts configured to engage with each other in a telescopic manner along a longitudinal axis, through a screw mechanism integrated in the first concentric shaft. The screw mechanism includes a bolt in an upper portion for mounting onto the first concentric shaft, and an externally threaded rod in a lower portion for engaging with an internally threaded first channel of the second concentric shaft. The second concentric shaft includes a second channel extending along corresponding length, and the externally threaded rod portion includes a third channel extending along corresponding length. Further, the second channel fully aligns with the third channel, when first and second concentric shafts engage in a telescopic manner upon rotation of the screw mechanism. The first and second concentric shafts include first and second set of guide holes for coupling to proximal and distal fragments of bone.
