Background
Hemivertebra(HV) is a complete failure of the formation of a vertebral
body 1. Sacral HV is a very rare congenital anomaly;
prior to this, about seven cases had been reported (Table 1).2-7 Posterior HV are wedge-shaped deformities caused
by failure of anterior vertebral formation, resulting in progressive
kyphosis. 8,9 The lumbosacral HV usually does not
present a risk of kyphosis deformity and previously in the case of
lumbosacral HV, no cases of kyphosis have been identified.10 A sacral HV between S1-S2 is too rare and just one
case had been reported previously which happened in a 10-month-old
infant and no explanation has been given about its clinical symptoms in
adulthood and the possible problems caused by it. 11In this article, the condition of a patient with an S1-S2 HV that cause
congenital Lumbosacral junction kyphosis (CLSJK)with a neurological
bladder is explained.
