Jeffrey P Mullin, Alvin Y Chan, Emily Bennett, Michael P Steinmetz
BACKGROUND: Bilateral extracavitary approach (BECA) is an option for decompression cases that require a more extended ventral approach. The clear advantage is increased accessibility to the most ventral aspects of the spine from a bilateral perspective. OBJECTIVE: To assess the safety and efficacy of thoracic and thoracolumbar decompression and/or reconstruction from BECA. METHODS: A retrospective chart review was performed reviewing all patients who underwent BECA for thoracolumbar decompression from 2003 to 2012 at our institution...

OBJECTIVE: To discuss the causes of unsatisfied cervical posterior decompression surgery and describe the overhauling strategies and precaution. METHODS: The clinical data of 14 patients required revision surgery were retrospectively analyzed, and these patients with unsatisfied effects were due to cervical posterior decompression surgery from January 2012 to December 2014. Overhauling reasons were analyzed and then different revision procedures were performed. The functions of cervical cord and ambulation were evaluated respectively by modified Japanese Orthopedic Association(mJOA) score and Nurick grade according to the course order:preoperative for the first time, pre-revision and at final follow-up...

BACKGROUND: Very severe osteoporotic vertebral compression fractures (vsOVCFs) are osteoporotic vertebral compression fractures with vertebral body collapse to less than one third of their original height. Few data are available about the use of percutaneous kyphoplasty (PKP) in treating vsOVCFs with spinal canal compromise. The aim of this study was to evaluate the safety and efficacy of percutaneous kyphoplasty (PKP) for the treatment of vsOVCFs with spinal canal compromise. METHODS: Thirty-five patients who suffered vsOVCFs with spinal canal compromise but without neurological deficits were treated by PKP between January 2009 and October 2014...

BACKGROUND: Sagittal translation (ST) is an accidental event that surgeons commonly encounter during a spinal osteotomy in the correction of kyphosis in ankylosing spondylitis (AS). However, there is a paucity of effective techniques to prevent ST. The purpose of this study was to propose a pedicle subtraction osteotomy (PSO) with a cage as a method to prevent ST and to explore the efficacy and feasibility of this method in the treatment of kyphosis in AS. METHODS: We retrospectively reviewed 89 consecutive patients with AS kyphosis who underwent a PSO (Group B, 46 patients) or a PSO with a cage (Group A, 43 patients) from February 2009 to December 2013...

BACKGROUND: It remains unclear whether long fusion including lumbar-sacral fixation is needed in corrective surgery to obtain good global sagittal balance (GSB) for the treatment of traumatic thoracolumbar kyphotic spine deformity. The purposes of this study were to evaluate compensatory mechanism of the spine after corrective surgery without lumbar-sacral fixation and to evaluate the parameters affecting the achievement of good GSB post-operatively. METHODS: Twenty (20) subjects requiring corrective surgery (distal end of fixation was L3) were included in this study...

STUDY DESIGN: Retrospective study. OBJECTIVE: To evaluate how each type of sagittal cervical alignment affects the motion of the upper and subaxial cervical spine using kinematic magnetic resonance imaging. SUMMARY OF BACKGROUND DATA: The sagittal malalignment of the cervical spine from degeneration in the subaxial cervical spine reflects a disruption in the kinematic properties of the cervical spine and affects the motion of adjacent segments...

BACKGROUND CONTEXT: Sagittal translation, a potential complication of pedicle subtraction osteotomy (PSO), can results in neurologic damage. However, few studies have been conducted on sagittal translation and its risk factors after PSO in patients with ankylosing spondylitis (AS). PURPOSE: To report cases of sagittal translation that developed after PSO in patients with AS with kyphotic deformity and to analyze risk factors for sagittal translation. STUDY DESIGN: A retrospective case-control study PATIENT SAMPLE: This study included 53 patients (58 cases) with AS who underwent PSO to correct their kyphotic deformity...

OBJECTIVE: The purpose of this study was to compare the effect of atlantoaxial fixation on cervical alignment and clinical outcomes in patients with os odontoideum (OO) versus non-os odontoideum (non-OO). METHODS: A total of 119 patients who underwent atlantoaxial fixation for instability were identified between January 1998 and January 2014. Inclusion criteria included age more than 21 years and diagnosis of OO and non-OO. There were 22 OO patients, and 20 non-OO patients...

CASE: Spinal fractures are rare in young children. Because spinal anatomy and biomechanics differ in children and adults, knowledge of the deviations of the juvenile spine is necessary for adequate treatment. We present the case of a young girl with an unusual C2 fracture that included rupture of both of the neurocentral and lateral dental synchondroses, with an opening of the synchondroses and a caudal dislocation of both vertebral arches following a head-on motor vehicle collision. The whole body and apex of the dens was displaced anteriorly and cranially with a kyphotic angulation of 34°...

Study Design: Prospective clinical study. Purpose: The purpose of this study was to evaluate the effect of interlaminar fusion and short segment pedicle screw fixation on thoracolumbar vertebral injuries for preventing pain and post-traumatic kyphosis. Overview of Literature: The treatment of thoracolumbar injuries continues to be one of the most controversial areas in spine care. The main aim of surgical treatment is to decompress the spinal cord or nerve roots, realign the spine, and correct or prevent post-traumatic kyphosis...

Study Design: Retrospective review. Purpose: To describe a safe and effective surgical procedure for old distractive flexion (DF) injuries of the subaxial cervical spine. Overview of Literature: Surgical treatment is required in old cases when a progression of the kyphotic deformity and/or persistent neck pain and/or the appearance of new neurological symptoms are observed. Since surgical treatment is more complicated and dangerous in old cases than in acute distractive-flexion cases, the indications for surgery and the selection of the surgical procedure must be carefully conducted...

BACKGROUND Percutaneous kyphoplasty (PKP) has been widely used to treat vertebral compression fractures (VCFs). Bilateral percutaneous punctures are always performed to access the fractured vertebrae. However, the procedure has expensive clinical costs, especially the cost for the device, which creates a heavy financial burden for patients. MATERIAL AND METHODS Data from 49 patients who have single-level non-neoplastic vertebral compression fracture (VCF) were collected for 12 months after treated by PKP, including 21 cases that used bilateral puncture with single balloon (S group) and 28 cases that used bilateral puncture with double balloon (D group)...
