Do low-density screws influence pelvic incidence in adolescent idiopathic scoliosis correction?

Background: Low-density screw constructs yield significant radiographic and clinical improvements with reduced risk of neurological complications. This study aimed to investigate the relationship between coronal Cobb angle and pelvic incidence (PI) in the correction of adolescent idiopathic scoliosis (AIS) using a low-density construct, as well as the association between PI and functional outcomes.

Patients And Methods: This prospective cohort study involved 60 posteriorly instrumented AIS patients, aged 10-16 years, with Cobb angles ranging from 45° to 90° of various Lenke types.

The use of platelet-rich fibrin in lumbar interbody fusion in lytic spondylolisthesis.

Study Design: This was a retrospective observational study.

Aim: The aim of this study was to evaluate the effectiveness of applying the platelet-rich fibrin (PRF) with bone graft in accelerating the rate of lumbar interbody fusion.

Settings And Design: This was a retrospective study measuring the outcome of posterior lumbar interbody fusion (PLIF) combined with PRF versus PLIF alone in the management of lytic spondylolisthesis.

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.

Single stage anterior reconstruction using titanium mesh cages in neglected kyphotic tuberculous spondylodiscitis of the cervical spine.

Cervical tuberculous spondylodiscitis is a serious, hazardous disorder and to our knowledge, hardly any reports focused on the use of titanium mesh cages in its treatment. The aim of this work is to evaluate the efficacy of using a titanium mesh cage compared to iliac crest grafting regarding correction of the deformity, fusion rate and to report the incidence of complications. A prospective, non-randomized multicentre study of 30 patients with cervical tuberculous spondylodiscitis presenting with a neglected kyphotic deformity.

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.

All pedicle screw instrumentation for Scheuermann's kyphosis correction: is it worth it?

Background Context: Scheuermann's kyphosis has long been treated by a two-staged fusion and instrumentation with a hybrid construct using hooks, pedicle screws, and sublaminar wires. Recent interest in all pedicle screw constructs led to its use in the treatment of Scheuermann's kyphosis. Evaluation of this newly described application is needed.
