In case of delay of consolidation of a fracture, biological processes can still be directed toward healing, to avoid the possible evolution of the outbreak in non-union, situation only treatable surgically. Non-surgical therapies in case of delayed consolidation which have been proved effective in accelerating bone repair processes, are magnetotherapy, treatment with shock waves and, in very special cases, hyperbaric oxygen therapy. The magnetotherapy indicated for facilitating the bone repair processes uses pulsed electromagnetic fields at low intensity (CEMP). Therapy should last at least 6 - 8 hours a day, not necessarily in succession, for example during the night. The therapeutic efficacy of the CEMP also concerns pain, edema and inflammation that may be associated with delayed consolidation.
