Role Of Percutaneous Bone Marrow Injection In Delayed Union And Non Union.

The present study was conducted in the Department of orthopaedics, Government Medical College, Jammu over a period of one year from June 2005 to May 2006 to evaluate the efficacy of percutaneous bone marrow injection in cases of delayed union and non-union. 50 cases of post-traumatic delayed and non-union (out of 50 cases, 38 were of delayed union and 12 were of non-union), irrespective of their age and sex, were selected from Orthopaedic OPD. Forty-six (92%) out of 50 cases had successful union while four had failures. ln case of delayed union, 37 out of 38 (97.37%) patients had successful union and one case did not respond to bone marrow injection. 9 out of 12 (75%) cases of non-union resulted into union where as 3 cases failed to unite. Most of the patients in our series responded to bone marrow injection with union between 12-20 weeks and in cases of delayed union, mean time taken for union to occur was 14.6 weeks and for non-union, mean time taken to unite was 18.4 weeks.
