Offset sublaminar hook is an efficient tool for the prevention of distal junctional failure after kyphotic deformity correction.

Purpose: To assess the radiological outcomes and complications focusing on distal junctional failure (DJF) of adult spinal deformity patients who underwent thoracolumbar fixation with the use of offset sublaminar hooks (OSH) distally.

Methods: Retrospective review of a prospective, multicenter adult spinal deformity database (2 sites). Inclusion criteria were age of at least 18 years, presence of a spinal deformity with thoraco-lumbar instrumentation ending distally with OSH (pelvis excluded), with minimum 2 years of follow-up.

Domino connector for thoracic pedicle subtraction osteotomy reduction: surgical technique and patient series.

Purpose: Different techniques have been previously described to close the pedicle subtraction osteotomy (PSO) site for correction of sagittal malalignment; the use of a side-to-side domino connector as a correction tool in the thoracic spine has not been specifically studied.

Methods: Twenty adult patients who underwent single-level thoracic PSO from T1 to T12 were included and retrospectively reviewed (two centers). Preoperative and postoperative full-body X-rays, perioperative data, clinical data and complications were recorded with a minimum 2 years of follow-up.

Brucellosis of the spine - A global public health problem - An analysis of 37 patients from a 'high risk' region.

Background: Brucellosis is a global public health issue. Brucellosis of the spine presents as a wide spectrum. The aim was to present the outcome analysis of patients treated for Spinal Brucellosis in the endemic region.

Delayed atlantoaxial rotatory dislocation in a child with Crohn's disease: illustrative case.

Background: Atlantoaxial rotatory dislocation (AARD) in children may be caused by neck trauma or an upper respiratory tract infection. Here the authors describe the very rare association between inflammatory bowel disease and AARD in a child.

Observations: A 7-year-old girl presented with an 11-month history of torticollis that occurred spontaneously without a trauma context.

Brucellosis of the Spine in Children-An Analysis of 5 Children From an Endemic Setting.

Background: Brucellosis of the spine is quite common among adults in endemic regions. The incidence of brucellosis of the spine affecting children is very rare. This article describes the clinical characteristics, diagnosis, management and outcome of children with brucellosis of the spine.

Accuracy of percutaneous pedicle screw insertion in spinal fixation of traumatic thoracic and lumbar spine fractures.

Background: Percutaneous insertion of pedicle screws was developed as a minimally invasive alternative to the different open spinal procedures. Here, we determined the accuracy of percutaneous pedicle screw insertion.

Methods: For 60 consecutive patients with thoracic/lumbar spine fractures, computed tomography (CT) studies were utilized to assess the accuracy of percutaneous pedicle screw positioning.

Modified closing-opening wedge osteotomy for the treatment of sagittal malalignment in thoracolumbar fractures malunion.

Background Context: Many techniques have been described for the surgical treatment of rigid posttraumatic thoracolumbar kyphosis, but none is well adapted to the modified shape of the wedged vertebra.

Purpose: The study aimed to describe the modified closing-opening wedge osteotomy (MCOWO), a new osteotomy technique that adapts to the triangular shape of the wedged apical vertebra of the deformity.

Study Design: A retrospective assessment of the degree of correction before and after the MCOWO was carried out.

Pediatric Upper Cervical Spine Giant Cell Tumor: Case Report.

Study Design Case report. Objective The purpose of this work is to report the case of a giant cell tumor involving the second cervical vertebra in a pediatric patient. Surgical management included a combined posterior and anterior cervical approach.

Brown tumor of the cervical spines: a case report with literature review.

To report a rare case of axis brown tumor and to review literature of cervical spine brown tumor. Brown tumor is a rare bone lesion, incidence less than 5% in primary hyperparathyroidism. It is more common in secondary hyperparathyroidism with up to 13% of cases.

Role of the O-arm and Computer-assisted Navigation of Safe Screw Fixation in Children with Traumatic Rotatory Atlantoaxial Subluxation.

Study Design: A retrospective analysis of 7 patients with traumatic rotatory atlanto-axial subluxation.

Overview Of Literature: Cases of traumatic rotatory atlantoaxial subluxation in children are difficult to be stabilized. Surgical challenges include: narrow pedicles, medial vertebral arteries, vertebral artery anomalies, fractured pedicles or lateral masses, and fixed subluxation.

Direct transoral reduction of anteriorly displaced type II odontoid fracture during anterior odontoid screw fixation: Review of literature.

Background: The anteriorly displaced type II odontoid fracture is treated either conservatively by halo-vest brace immobilization or surgically by posterior atlantoaxial fusion. Anterior odontoid screw fixation is not advised for this pattern of odontoid fracture because of the difficult trajectory for screw insertion despite its advantage of salvaging the upper cervical spine rotatory range of movement. This article presents a new transoral manipulation technique for reduction of anteriorly displaced type II odontoid fracture and review of the literature.

Guidewire breakage: an unusual complication of anterior odontoid cannulated screw fixation.

The preferred treatment of a type II odontoid fracture is anterior odontoid screw fixation to preserve the cervical spine range of movement. This case report describes an unusual complication of guidewire breakage during anterior odontoid cannulated screw fixation for a 52-year-old patient who presented with a type II odontoid fracture after a motor vehicle accident. The distal segment of the guidewire was bent over the tip of the cannulated odontoid screw and broke off during guidewire withdrawal.

Spontaneous resorption of sequestrated intervertebral disc herniation.

Objective: The aim of this study is to describe six cases with spontaneous resorption of sequestrated intervertebral disc herniation observed using magnetic resonance imaging. In addition, the possible mechanisms, predictive factors of spontaneous disappearance of the sequestrated disc herniation, and the proper surgical timing were discussed and reviewed in literature.

Methods: All the studied cases experienced acute radicular pain due to sequestrated intervertebral disc herniation; they refused surgery and were treated conservatively, and they were followed up neurologically and radiologically in the outpatient clinic in regular visits.
