Spanish to English Medical Medical (general) post-sternotomy complicatations after heart surgery

Hello again

I am still translating the article about post-sternotomy complications in children.

I am unable to find "osteogenic reaction" anywhere and would appreciate some help with this phrase.

Here is the context, and my attempt at a translation follows:

La gammagrafia ósea con doble trazador (Ga67 y Tc99) no mostró ****reacción osteogénica**** pero era muy sugestiva de infección local afectando a hueso esternal.
Los hemocultivos fueron estériles y los cultivos de la herida fueron positivos a S. Aureus y S. Epidermidis, ambos sensibles a oxaciclina.

A double-tracer (Ga67 and Tc99) bone scan did not reveal any ****osteogenic reaction**** but strongly suggested a local infection affecting the sternal bone. Blood cultures were sterile and wound cultures were positive for S. Aureus and S. Epidermidis; both were sensitive to oxytetracycline

Thank you!
