ORTHOPLASTY

Subchondral bone plasty

The subchondral bone plasty procedure is a minimally-invasive, fluoroscopically-assisted procedure that identifies and repairs subchondral bone defects, also named Bone Marrow Lesions (BML).
It is commonly executed with arthroscopy, to target and manage of findings inside the joint.

BENEFITS

  • Safe and precise MIS Approach
  • Reduced risk of infections
  • Ready-to-use bone substitute, no preparation needed
  • Hardening in wet envitonment only: no time pressure during application
  • Truly biologic: composed by a micro-crystalline, calcium deficient hydroxyapatite – major bone constituent
  • High load sharing properties (up to 45 MPa)
  • Radio-opaque paste: clearly visible under fluoroscopy and X-rays
  • Bioresorbable during bone remodeling

APPLICATION

  • DISTAL FEMUR
  • PROXIMAL HUMERUS
  • PROXIMAL TIBIA
  • ANKLE JOINT
  • FEMORAL HEAD
  • HIP

SURGICAL TECHNIQUE

1. Identify the Bone Marrow Lesion (BML) using a fat-suppressed MRI (T2) and choose the optimal approach and trajectory
2. Through intraoperative fluoroscopy target the defect associated with Bone Marrow Lesion (BML) linked to the MRI results
3. Access bone defect using Orthoplasty access tools kit
4. Fill bone defect with bone substitute under fluoroscopic guidance
5. Alternatively, BML defects can be filled with Marrow-Stem kit, using the creeping substitution technique and marrow mesenchymal stem cells instead of a bone substitute
