Microendoscopic Discectomy Combined with Annular Suture Versus Percutaneous Transforaminal Endoscopic Discectomy for Lumbar Disc Herniation: A Prospective Observational Study.

Background: Microendoscopic discectomy (MED) and percutaneous transforaminal endoscopic discectomy (PTED) are 2 of the most popular minimally invasive spinal surgery techniques. We are investigating whether minimally invasive early annular closure can achieve a better clinical effect in the treatment of lumbar disc herniation (LDH).

Objective: To compare the clinical and imaging outcomes between MED combined with annular suture and PTED in the treatment of LDH.

Anterior reduction and fusion for acute unilateral cervical facet dislocation without severe spinal cord injuries.

Purpose: This study aimed to evaluate safety and effectiveness of simple anterior reduction and fusion for acute lower cervical unilateral facet dislocation without severe spinal cord injuries.

Materials And Methods: One hundred and two patients with unilateral cervical facet dislocations without severe spinal cord injuries who were surgically treated by the only anterior approach were analyzed. The treatment effects were evaluated based on the Visual Analogue Scale (VAS) scores, the Cobb angle of kyphosis, the Neck Disability Index (NDI) and Odom's criteria.

Comparison of anterior and posterior approaches for treatment of traumatic cervical dislocation combined with spinal cord injury: Minimum 10-year follow-up.

Anterior reduction and interbody fusion fixation has not been compared directly with posterior reduction and short-segmental pedicle screw fixation for lower cervical dislocation, and so consensus is lacking as to which is the optimal method. The purpose of this paper is to compare long-term outcomes of the anterior versus posterior approach for traumatic cervical dislocation with spinal cord injury. One hundred and fifty-nine patients could be followed for more than 10 years (follow-up rate 84.

Transforaminal Endoscopic Lumbar Discectomy for Lumbar Disc Herniation Causing Bilateral Symptoms.

Background: Transforaminal endoscopic lumbar discectomy (TELD), a minimally invasive spinal technique, has advantages over open discectomy. Unilateral TELD for disc herniation causing bilateral symptoms is challenging. In this study, we describe a percutaneous endoscopic herniotomy technique by using a unilateral approach for lumbar disc herniation with bilateral obvious symptoms.

Evaluation of Bioabsorbable Multiamino Acid Copolymer/Nanohydroxyapatite/Calcium Sulfate Cage in a Goat Spine Model.

Background: Currently, polylactide is the most popular material used to made bioabsorbable cages but too-quick degradation and osteolysis around the cage have been reported in the literature. This study evaluated the fusion effect, biomechanical stability, and histologic characteristics of a novel bioabsorbable multiamino acid copolymer/nanohydroxyapatite/calcium sulfate (MAACP/n-HA/CS) interbody cage in a goat model of anterior cervical discectomy and fusion.

Methods: A total of 24 goats underwent C3/C4 discectomy and fusion with 3 groups of intervertebral implants: MAACP/n-HA/CS cage group (n = 8), titanium cage group (n = 8), and autologous tricortical iliac crest bone group (n = 8).

Effectiveness and safety of unilateral pedicle screw fixation in transforaminal lumbar interbody fusion (TLIF): a systematic review and meta-analysis.

Purpose: To evaluate the effectiveness and safety of unilateral pedicle screw fixation in transforaminal lumbar interbody fusion (TLIF) by comparing with bilateral pedicle screw fixation.

Materials And Methods: PubMed, EMBASE, and the Cochrane Central Register of Controlled Trial database were used to search and identify clinical prospective trials that evaluated the efficacy and safety of unilateral fixation as compared with bilateral fixation in TLIF surgery. The methodological qualities of studies were assessed using the PEDro (Physiotherapy Evidence Database) score and Newcastle-Ottawa Scale.

[EXPERIMENTAL STUDY ON POLY-AMINO ACID/NANO-HYDROXYAPATITE/CALCIUM SULFATE CAGE FOR LUMBAR INTERBODY FUSION IN GOATS].

Objective: To evaluate the effect of poly-amino acid/nano-hydroxyapatite/calcium sulfate (PHC) Cage in lumbar interbody fusion of the goat.

Methods: Eighteen mature female goats (weighing 29-33 kg) were divided into 3 groups randomly: PHC Cage group (group A), titanium Cage group (group B), and ilium group (group C). A left extraperitoneal approach was used to establish the animal model of discectomy and interbody fusion with Cage or ilium.

Recurrent primary lumbar vertebra chondrosarcoma: Marginal resection and Iodine-125 seed therapy.

Chondrosarcomas are uncommon in the spinal column. En bloc excisions with wide margins are of critical importance but not always feasible in spine. We report the outcome in a case of recurrent lumbar vertebral chondrosarcoma treated with marginal resection and iodine-125 seeds placed in the resected tumor bed.

Adjacent segment degeneration and disease after lumbar fusion compared with motion-preserving procedures: a meta-analysis.

Purpose: The purpose of our study was to compare lumbar fusion and motion-preserving procedures to determine whether lumbar fusion may be associated with a higher prevalence of adjacent segment degeneration (ASDeg) or adjacent segment disease (ASDis).

Methods: We performed a systematic review and meta-analysis for articles published up to July 2013. We included randomized controlled trials and cohort studies that reported ASDeg or ASDis after lumbar fusion compared with motion-preserving devices.

Comparison of anterior and posterior vertebral column resection versus anterior release with posterior internal distraction for severe and rigid scoliosis.

Purpose: This study aimed to compare efficacy, safety, and cost between staged vertebral column resection (VCR) and anterior release with internal distraction in treating severe and rigid idiopathic scoliosis.

Methods: We examined the records of 43 patients with severe and rigid idiopathic scoliosis treated in our hospital. Group A included 26 patients who underwent anterior VCR followed by posterior vertebral column resection and instrumentation from July 2007 to October 2009.

Mid- to long-term outcomes after cervical disc arthroplasty compared with anterior discectomy and fusion: a systematic review and meta-analysis of randomized controlled trials.

Purpose: To evaluate the mid- to long-term clinical outcomes after cervical disc arthroplasty (CDA) as compared with anterior cervical discectomy and fusion (ACDF) for the treatment of symptomatic cervical disc disease.

Methods: A systematic review and a meta-analysis were performed for articles published up to March 2013. Randomized controlled trials that reported mid- to long-term outcomes (≥48 months) after CDA as compared with ACDF were included.

Comparison of anterior cervical fusion by titanium mesh cage versus nano-hydroxyapatite/polyamide cage following single-level corpectomy.

Purpose: The titanium mesh cage (TMC) is a typical metal cage device which has been widely used in cervical reconstruction for decades. Nano-hydroxyapatite/polyamide-66 (n-HA/PA66) cage is a novel biomimetic non-metal cage device growing in popularity in many medical centres in recent years. There has been no comparison of the efficacy between these two anterior reconstructing cages.
