Letter to the Editor


Butterfly vertebra consists of two hemivertebrae with a sagittal cleft between them, resulting in the special appearance of butterfly wings on anteroposterior spine radiograph. This rare congenital anomaly is not only been reported in clinical cases, but also in dry bone specimens from archaeological excavations. To date, most clinical case reports on butterfly vertebra have mainly focused on the imaging findings, and few studies discuss on its treatment strategy. Notably, a minority of patients may experience slowly progressive spinal deformity after the initial surgery due to the great growth potential of butterfly vertebra and implant failure. Many of these patients suffer from further deterioration of symptoms with time, thus require repeat surgical intervention. Our objective was to determine the causes of failure of primary surgery and to explore new treatment strategy. Herein, we report an unusual case of butterfly lumbar vertebra underwent revision surgery and...
