OBJECTIVE To report the successful correction of a severe, fixed kyphotic deformity utilizing a combination posterior lumbar interbody fusion (PLIF) and Ponte osteotomy at the site of acute kyphosis. SUMMARY OF BACKGROUND DATA There have been no reports on the experience and surgical strategy of combined one-level focal PLIF and Ponte osteotomy for fixed severe kyphotic deformity. Typically, ...

Thoracolumbar fractures are an important topic in spinal surgery. In this article, the instability of the thoracolumbar fracture classifications and surgical treatments are discussed, with a particular focus on treatment concepts that are based on the modern classification systems. Introduction Thoracolumbar junction has unique anatomical and biomechanical features because of this region is a t...

spondylitis is a reemerging epidemic spinal infection in male broiler chickens (5 to 7 weeks of age) as well as broiler breeder roosters (15 to 18 weeks of age). among various causative agents, enterococcus species and in particular e. cecorum, a gram-positive bacterium as a gastrointestinal flora of birds, have mostly been isolated. on late september 2015, a number of 10 weeks old roosters wit...

INTRODUCTION Polymethylmethacrylate (PMMA) cement is useful for spinal reconstruction, but can cause complications including new vertebral fractures, neurological disorders and pulmonary embolism. We report a case in PMMA cement used for spinal reconstruction after tumor curettage dislodged and penetrated the gastrointestinal tract. DIAGNOSES The patient was diagnosed with a retroperitoneal e...

Vertebral column resection is associated with a risk of spinal cord injury. In the present study, using a goat model, we aimed to investigate the relationship between changes in spinal cord volume and spinal cord injury due to spinal shortening, and to quantify the spinal cord volume per 1-mm height in order to clarify a safe limit for shortening. Vertebral column resection was performed at T10...

Giant cell tumors (GCTs) are rare, benign, and locally aggressive primary bone neoplasms. Spine is seldom affected, especially above the level of sacrum. In this report, we describe a case with GCT of the cervical vertebrae which causes collapse of the corpus. A 32-year-old female presented with gradual neck pain and abrupt paresthesia of the left hand. Computed tomography scan showed C6 verteb...

To the Editor: We read with great interest article by Theodore et al1 entitled “Posterior Vertebral Column Subtraction Osteotomy for Recurrent Tethered Cord Syndrome: A Multicenter, Retrospective Analysis,” recently published in Neurosurgery. The authors elegantly analyzed a multicenter, retrospective cohort of 20 adult patients (mean age 36 yr) recurrent tethered cord syndrome (TCS) which unde...

Study Design Case report. Objective We report the youngest child diagnosed with upper cervical osteoblastoma and the first case operated on with our novel surgical approach. Methods Our patient underwent a two-stage surgery. During the first operation via a posterior approach, a subtotal resection of a C2 bony mass was performed. C3 was also subtotally resected due to tumor extension. Posterior...
