Patients consulting orthopedics often receive alternative treatment. We report two cases developing complications due to alternative treatment. Case1 was a 78-year-old female with degenerative spondylolisthesis whose neurological symptoms aggravated due to alternative treatment. Case2 was an 80-year-old female suffering T11 and 12 compression fractures by spinal manipulation. This paper discusses the present situation and problems of alternative treatment in Japan.
