To date, few studies have addressed the subaxial vertebrectomy technique and related anatomical landmarks in this method. Total spondylectomy is performed via piecemeal resection or en bloc removal in a one-stage procedure associated with stabilizing the spine and preserving neurological status. In this presentation, a circumferential total cervical tumor resection for subaxial cervical spine l...

A 30 years old male presented to us with history of back pain and weakness of both lower limbs for the last four months and was diagnosed by local orthopedic surgeon as a case of carries spine. He also used anti tuberculous drugs for two months but there was no improvement in his symptoms. We planned for transpedicular spinal biopsy. Biopsy report came to be non specific chronic inflammation. W...

Conspicuous vertebral column abnormalities in humpback dolphins (genus Sousa) were documented for the first time during 3 photo-identification field studies of small populations in Taiwan, Senegal and Angola. Seven Taiwanese humpback dolphins S. chinensis taiwanensis with vertebral column anomalies (lordosis, kyphosis or scoliosis) were identified, along with 2 possible cases of vertebral osteo...

This study reports the case of a 44-year-old male who had experienced severe neck pain for one month and was diagnosed with a metastatic tumor of the left C2 vertebral body and the left transverse process. The tumor was distributed to layers A-D and sectors 3-7 according to the Weinstein-Boriani-Biagini classification, and was in Category IV according to the Harrington classification system. A ...

Background: Posterior tibial tendon insufficiency plays a large role in the pathogenesis of adult acquired flatfoot deformity (AAFD) in select patients. Transfer of the flexor digitorum longus is indicated to compensate for the loss of posterior tibial tendon function; however the role of resection of the degenerated posterior tibial tendon remains unclear. The aim of this study was to determin...

Rib-vertebrae (rv) is an autosomal recessive mutation in mouse that affects the morphogenesis of the vertebral column. Axial skeleton defects vary along the anterior-posterior body axis, and include split vertebrae and neural arches, and fusions of adjacent segments. Here, we show that defective somite patterning underlies the vertebral malformations and altered Notch signaling may contribute t...

THIS REPORT deals with 3 cases of proliferative disease of the bone in Matschie tree kangaroos (Dendrolagus matschiei) at the National Zoological Park. The osseous lesions had similar radiographic manifestations but dissimilar causes. One kangaroo had tuberculous osteomyelitis of the vertebral column and radius; the 2nd had a chondrosarcoma of the vertebral column and femur; and the 3rd had bil...
