Modalities Enhancing Natural Biological Fracture Healing :

Enumerate modalities leading to biological enhancement of fracture healing - This is a routine DNB Theory Question and often asked in Short Cases of Non Union in Practicals.

Modalities Enhancing Natural Biological Fracture Healing :

1.PEMF ( Pulsed Electromagnetic Fields ) : It is based on the discovery of electrical currents in bone that were generated in response to normal functioning mechanical loads. The PEMF’s are induced by a Square Wave Generator ( Faraday’s Law ). Optimal Frequency for Bone Growth : 15-30 Hz

2.Ultrasound : Accelerates Fracture Healing with short ( 15-20 minute ) daily treatment at 30 mW/cm2

3.Bone Marrow Injections ( Application of 20 ml of marrow harvested from iliac crest or greater trochanter for non unions < 5 mm )

4.Stem Cell Injection ( 100-150 ml bone marrow centrifuged to produce 2-4 ml aspirate containing multipotent marrow cells and osteogenic stromal cells )

5.Platelet rich plasma and related peripheral blood concentrates

6.External Shock Wave Therapy

7.Bone Morphogenetic Proteins ( BMP ) : BMP 2 / BMP 7 / BMP 14
