COREX Case Studies
Explore how surgeons are using COREX to harvest cancellous bone graft using a minimally invasive technique.
Learn Why Autologous Bone is the First Choice for Spine Fusions
Distal Tibia Harvest
Figure 1. Intraoperative photograph of COREX minimally invasive bone harvester being utilized in the distal tibia (A) to harvest cores of autogenous bone graft (B).
Intraoperative image intensification images demonstrating creation of cortical access window (C) and the COREX device being passed in multiple angles (D, E, F) through the distal tibial metaphyseal bone for harvest.
Calcaneus Harvest
Figure 2. Intraoperative image intensification demonstrating autogenous bone graft harvest site within the calcaneus (A) after using the COREX minimally invasive bone harvester to produce multiple cores of autogenous bone (B) to augment a great toe joint arthrodesis.

Postoperative weightbearing AP (D) and lateral (E) foot radiographs demonstrating complete healing of arthrodesis site and no complications at calcaneal bone graft harvest site.
The Key Properties Required for Effective Grafts
Osteoinductive
Active recruitment and stimulation of stem cells, differentiate into osteoblasts and form new bone.
Osteoconductive
Passive scaffold to maintain space and allow for bone formation.
Osteoconductive
Osteogenic living cells, such as osteoblasts, make new bone. Osteoprogenitor cells can proliferate and differentiate to osteoblasts which turn into osteocytes.
