BackgroundLumbosacral transitional vertebrae (LSTV), is a structural anomaly, of the lumbosacral spine which has been variably associated with, low back pain (LBP) and its presence can also result in a level being wrongly identified pre-operatively.ObjectivesTo determine the incidence, pattern of LSTV and its relationship with LBP in our tertiary hospital.MethodsA retrospective review of lumbosacral spine radiographs of 561 one consecutive patients with history of LBP was done from January 2006 to January 2008. The presence or absence of LSTV and degenerative changes were documented.ResultsFifty-one ((9.1%)) out of 561 patients had LSTV. Type II (incomplete) LSTV was the commonest type, occurring in 86.3% of patient with LSTV. Patients less than 30yrs with LBP and LSTV had no degenerative changes, while all patients with LSTV above 50 yrs had degenerative changes.ConclusionLumbosacral transitional vertebrae type II was the commonest seen in this study, furthermore, LSTV appears to be a causative factor of LBP in young individuals. Careful evaluation of spinal radiographs of patients with LBP belonging to this group is advocated to assess for the presence or absence of LSTV.
