Bone transplantation
Study 1
Bone transplantation (fusion two vertebrae through)**
Authors, title of the study and source:
Mooney V: A randomized double-blind prospective study of the efficacy of pulsed electromagnetic fields for inter body lumbar fusions. Spine 1990;15:708-712
Number of patients: 195, Multicentre
Disease:
Necessity of the vertebra fusion through: slipped disc, Spondylisthesis, inter vertebral disc degeneration, failure of previous methods of fusion, spinal canal constriction and other diseases
Treatment:
8 pcs/day
Improvement:
In 92.2% of patients in the MFT group, a radio logically detected fusion occurred after the bone grafting, versus 67.9% in the placebo group. Factors such as gender, age, level of fusion, number of transplants, Transplantation type, and internal fixation had no influence. Smoking had a small negative effect on the healing
Remarks:
Confirmed by other studies, which describe the effectiveness of MFT with many bone –ligaments and wound healing problems.
Study 2
Bone transplantation after bone tumour resection **
Authors, title of the study and source:
Capanna R, Donati D, Masetti C, et al: Effect of electromagnetic fields on patients undergoing massive bone transplantation following bone tumour resection. A double-blind study. Clin Orthop 1994:213-221
Number of patients: 47
Disease:
Removal of malignant processes of bone with subsequent bone transplantation of various kind
Treatment:
75 Hz, 8 pcs/day, 12 months
Improvement MFT had no effect when the total number of patients were compared within the groups, but in the sub-group which had no chemotherapy (9 in each group),the healing time of the MFT group was significantly shorter (6.7 months versus 9.4 months)
Remarks:
The authors present the hypothesis that the MFT cannot be effective if the cell growth is suppressed by the chemotherapy. The authors consider the MFT for completely risk-free and quote cell studies and studies on humans with cancer (including brain tumours), which demonstrate that MFT causes no tumour growth and causes no side effects or adverse cases.
** The treatment with pulsating magnetic field seems to be superior because of double blind controlled randomized studies of the Placebo-treatment.
* The treatment with pulsating magnetic field seems to be superior because of the controlled studies of the control-treatment.
