Abstract
Different conditions may lead to bone loss in bone infections. Septic non-unions, osteomyelitis, septic joint prosthesis are all conditions that may be associated with the need for bone grafts and/or of bone substitutes. The risk of infection recurrence makes, in these cases, particularly challenging the choice of the type of bone implant.
The use of growth factors, eventually associated with autologous or homologous bone grafts or with bone substitutes, may be helpful in restoring the bone stock, allowing to fill large bone defects, once the infection is controlled.
We present the preliminary results in 10 patients in which autologous Platelet Rich Plasma (PRP) has been used to treat large bone defect in two stage hip reconstruction (7 cases) and in previously infected non-unions (3 patients).
At a minimum follow-up of 6 months (maximum 18 months) a significant new bone formation occurred at the site of PRP application in all the cases treated and no signs of infection recurrence are present at the time of writing.
This is the first report on the short-term safety of use of PRP for the treatment of bone loss in previously infected bones in humans. The limited number of patients and the follow-up do not allow at the moment to drive any conclusion regarding the efficacy and safety in the long term, and the use of PRP with this indications should be limited to selected cases.
