%X <B>BACKGROUND: </B>Nutritional supplements are commonly used for a variety of musculoskeletal conditions, including knee and hip degenerative joint disease. Although these supplements are occasionally recommended for patients with degenerative disc disease and spinal degenerative joint disease, the evidence supporting this use is unknown.<BR><B>OBJECTIVE: </B>To systematically search and assess the quality of the literature on the use of glucosamine, chondroitin sulfate, and methylsulfonylmethane for the treatment of spinal osteoarthritis / degenerative joint disease, and degenerative disc disease.<BR><B>METHODS: </B>The Index of Chiropractic Literature, AMED, Medline, and CINAHL were searched for randomized controlled trials in English from 1984 to July 2009.<BR><B>METHODS: </B>Data from studies meeting the inclusion criteria was extracted and reviewed by three reviewers. The Jadad scale was used to assess study quality. No attempts were made at meta-analysis due to variation in study design.<BR><B>RESULTS: </B>Two articles met the inclusion criteria. One study was found to have good quality but reported negative results for the supplemented group compared with placebo, the other study had low quality but reported significant positive results for the supplemented group when compared with a no intervention control group.<BR><B>CONCLUSIONS: </B>There was little literature found to support the use of common nutritional supplements for spinal degeneration, making it difficult to determine whether clinicians should recommend them.
