 We assessed the coexistence of degenerative spondylolisthesis(DSO) in patients with hip osteoarthritis(OAH). Subjects were 247 women with OAH(aged 40-89). The configuration of the L4 lamina was classified into X and M+W based on the Oda classification. DSO in OAH was recorded in 31%. The incidence of DSO and the ratio of M+W type increased with age. DSO at L4/5 was recorded in 8% in X type and 41% in M+W type. Based on the fact that DSO occurs fairly commonly with OAH, a group of patients seems to develop OAH from the spine to the pelvis due to either genetic or hormonal factors. Otherwise, the high incidence of M+W type in older patients means that some cases with M+W type have been transformed by remodeling from X type due to dynamic factors related to hip contracture.
