FRACTURE REPAIR DEVICE REALIZING TRANSITION FROM MECHANICAL FIXATION (ASSOCIATION OF OSTEOSYNTHESIS, AO) TO BIOLOGICAL FIXATION (BIOLOGICAL OSTEOSYNTHESIS, BO) - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240041508 titled 'FRACTURE REPAIR DEVICE REALIZING TRANSITION FROM MECHANICAL FIXATION (ASSOCIATION OF OSTEOSYNTHESIS, AO) TO BIOLOGICAL FIXATION (BIOLOGICAL OSTEOSYNTHESIS, BO)

Simplified Explanation

The present disclosure describes a fracture repair device that allows for a transition from mechanical fixation to biological fixation during bone repair. The device includes a bone repair instrument with auxiliary components made of degradable metal material, composite material, or degradable polymeric material. These components are positioned close to the repaired bone surface. This device combines the advantages of rigid mechanical fixation with the ability to improve common issues such as bone disconnection, fixed segment osteoporosis, and re-fracture after defixation.

• The device enables a transition from mechanical fixation to biological fixation during bone repair.
• Auxiliary components made of degradable materials are positioned near the repaired bone surface.
• The device addresses common issues that occur under rigid mechanical fixation, such as bone disconnection and re-fracture after defixation.
• The device combines the advantages of mechanical fixation with improved bone repair outcomes.

Potential applications of this technology:

• Fracture repair in orthopedic surgery
• Bone fixation in trauma cases
• Bone repair in cases of osteoporosis

Problems solved by this technology:

• Bone disconnection during mechanical fixation
• Fixed segment osteoporosis
• Re-fracture after defixation

Benefits of this technology:

• Improved bone repair outcomes
• Reduced risk of bone disconnection and re-fracture
• Transition from mechanical to biological fixation for better long-term results

Original Abstract Submitted

the present disclosure discloses a fracture repair device realizing transition from mechanical fixation (association of osteosynthesis, ao) to biological fixation (biological osteosynthesis, bo), including: a bone repair instrument, wherein auxiliary components are arranged at positions, close to a repaired bone surface, of the bone repair instrument, and each auxiliary component is made of a degradable metal material or a composite material thereof or a degradable polymeric material. the device of the present disclosure only has the advantages of ao rigid mechanical fixation, but also can effectively improve the defects of bone disconnection, fixed segment osteoporosis, re-fracture after defixation, etc., frequently occurring under ao rigid mechanical fixation, realizing transition from mechanical fixation (association of osteosynthesis, ao) to biological fixation (biological osteosynthesis, bo) during bone fixation or repair.
