A comparative study between the Universal Spinal System (USS) and the CD Horizon Legacy™ (CDH) in the management of thoracolumbar fractures.

Introduction: For the treatment of unstable non-osteoporotic thoracolumbar fractures, the clinical and radiological outcome of short-segment fixation with the USS™ - Universal Spine System (DePuy Orthopedics, Inc., Warsaw, IN, USA) and the CD HORIZON LEGACY™ 5.5 Spinal System, (Medtronic Sofamor Danek USA, Inc.

The Adolescent Idiopathic Scoliosis International Disease Severity Study: Do Operative Curve Magnitude and Complications Vary by Country?

Background: The prevalence of adolescent idiopathic scoliosis (AIS) in diverse regions of the world has been studied. Access to care varies widely, and differences in disease severity and operative treatment outcomes are not well understood. This study aimed to determine variation in disease presentation and operative complications for AIS patients from an international cohort.

Minimally Invasive Transforaminal Lumbar Interbody Fusion for the Surgical Management of Post-Discectomy Syndrome.

Study Design: This was a prospective case series of 30 patients with post-discectomy syndrome with an average of 18 months of follow-up (level IV).

Purpose: The efficacy of post-discectomy syndrome managed by minimally invasive surgery transforaminal lumbar interbody fusion (MIS-TLIF) was evaluated.

Overview Of Literature: In post-discectomy syndrome wherein conservative treatment had failed, the best surgical treatment modality still remains controversial.

The use of anterior cervical interbody spacer with integrated fixation screws for management of cervical disc disease.

Introduction: Integrated cage and screw designs were introduced for anterior cervical discectomy and fusion (ACDF) and allegedly are superior to anterior plating due to their minimal anterior profile.

Methods: A descriptive study was designed as a prospective case series of 25 patients (30 operated discs) with cervical disc disease treated with a zero-profile cage, and followed up for an average of 16 months (range 12 -18 months). Functional assessment was done with the Neck Disability Index (NDI) and Visual analog scale (VAS) scores for arm and neck pain.

Augmentation of fenestrated pedicle screws with cement in patients with osteoporotic spine.

Background: Backing out and failure of pedicle screws in patients with osteoporosis is becoming a big problem due to wide use of these screws nowadays.

Purpose: The aim of this study is to evaluate the purchase of fenestrated pedicle screws augmented with cement in patients with osteoporosis.

Study Design: This was retrospective observational study.

Three-staged correction of severe rigid idiopathic scoliosis using limited halo-gravity traction.

Introduction: Despite the advantages of modern instrumentation techniques, the treatment of severe rigid idiopathic scoliosis could be very demanding. Traction can provide better, safer correction and minimize complications related to forceful intra-operative maneuvers; however, several side effects are associated with prolonged periods of traction. The aim of this work is to review the clinical and radiographic results of limited perioperative halo-gravity traction in severe rigid curves analyzing its efficacy, advantages and possible complications and comparing it to classic two staged corrections performed without traction.

Direct repair of spondylolysis presenting after correction of adolescent idiopathic scoliosis.

Background Context: Although spondylolysis is found in 6% of idiopathic scoliosis patients, very little was reported on management of pars defects in this group. These patients with painful spondylolysis are most eligible for direct repair of the defect rather than lumbosacral fusion in an attempt to save motion segments.

Purpose: The aim of this work was to analyze the clinical and radiologic outcome of pars repair in a group of adolescents who presented after surgical correction of their idiopathic scoliosis.

Surgical correction of severe dystrophic neurofibromatosis scoliosis: an experience of 32 cases.

The surgical management of severe rigid dystrophic neurofibromatosis curves is a demanding procedure with uncertain results. Several difficulties are present in such patients including a poor bone stock, sharp angulation of these dystrophic curves and dural thinning or ectasia. The aim of this work was to review the clinical and radiographic outcomes of three-dimensional correction of severe rigid neurofibromatosis curves analyzing its efficacy, safety and possible complications.

Transpedicular screw fixation for type II Hangman's fracture: a motion preserving procedure.

Opinions have varied regarding the optimal treatment of an unstable Hangman's fracture. C2 pedicle screw instrumentation is a biomechanically strong fixation which although done through a simple posterior approach, is a technically demanding procedure. This prospective, non-randomized multicentre study included 15 consecutive patients with displaced type II traumatic spondylolisthesis of the axis.

Anterior instrumentation and correction of congenital spinal deformities under age of four without hemivertebrectomy: a new alternative.

Study Design: Retrospective clinical and radiologic evaluation of a single-stage partial corpectomy of the hemivertebra with anterior instrumentation and simultaneous posterior noninstrumented fusion.

Objective: To determine the safety and efficacy of a new technique in the management of progressive congenital spinal deformities due to failure of formation in the very young age.

Summary Of Background Data: Several techniques have been reported for the surgical treatment of young children with congenital spinal deformities.
