BACKGROUND: Open lumbar microdiscectomy (OLM) has been considered the gold standard in the management of lumbar disc herniation (LDH) for its favorable outcomes in long-term follow-up. Nowadays, percutaneous endoscopic lumbar discectomy (PELD) is gaining recognition. However, greatest limitation of studies of PELD is the lack of long-term follow-up outcomes. OBJECTIVE: To investigate the long-term outcomes of PELD in terms of clinical and radiographic findings and revision surgery rate...

RATIONALE: Congenital scoliosis due to a hemivertebra creates a wedge-shaped deformity, which progresses and causes severe spinal deformities as an individual grows. The treatment of congenital scoliosis focuses on early diagnosis and appropriate surgical management before the development of severe deformity. PATIENT CONCERNS: We report the case of a 4-year-old male child with a left thoracolumbar scoliosis of 27° (T10-T12) due to a T11 hemivertebra who was treated by posterior fusion and pedicle screw fixation at the age of 4 years...

OBJECTIVE: Cervical artificial disc replacement (C-ADR) was developed with the goal of preserving mobility of the cervical segment in patients with degenerative disc disease. So far, little is known about experiences with revision surgery and explantation of C-ADRs. Here, we report our experience with revision the third generation, Galileo-type disc prosthesis from a retrospective study of two institutions. PATIENTS AND METHODS: Between November 2008 and July 2016, 16 patients with prior implantation of C-ADR underwent removal of the Galileo-type disc prosthesis (Signus, Medizintechnik, Germany) due to a call back by industry...

STUDY DESIGN: Retrospective cohort study at a single institution. OBJECTIVE: We aimed at estimating the rate of revision procedures and identify radiographic predictors of mechanical failure following adult spinal deformity surgery. SUMMARY OF BACKGROUND DATA: Mechanical failure rates following adult spinal deformity surgery range 12% to 37% in literature. While the importance of spinal and spino-pelvic alignment is well documented for surgical outcome and ideal alignment has been proposed as sagittal vertical axis (SVA) < 5 cm, pelvic tilt < 20° and lumbar lordosis (LL) = pelvic incidence ± 9°, the role of radiographic sagittal spine parameters and alignment targets as predictors for mechanical failure remains uncertain...

BACKGROUND: The mainstay treatment of primary malignant bone tumors is wide surgery in the spine as well. Unfortunately, most cases undergo the first approach in a non-specialized center; this often means adopting the inappropriate approach with contamination which consistently decreases the effectiveness of a second surgery. The aim of the present paper is to evaluate recurrence and survival rates after en-bloc resection. METHODS: All patients underwent wide resection by the senior author from January 1997 to December 2013 after the first inappropriate approach were reviewed...

PURPOSE: Anterior cervical discectomy and fusion (ACDF) is one of the most widely used procedures in cervical spine. Demineralized bone matrix (DBM) is one of the fusion options that has been used in treatment of the bone defects for years. The purpose of this review is to provide an evidence-based analysis on the current evidence for effectiveness of DBM in ACDF. METHODS: A systematic search of the literature was conducted using MEDLINE, Scopus, and CENTRAL. The risk of bias was evaluated with the criteria recommended by the Cochrane Back and Neck group and the Methodological Index for Non-Randomized Studies (MINORS)...

BACKGROUND: Though previous studies have shown improved outcomes associated with higher volume surgeons and hospitals, this may not be replicated in ASDS due to case complexity variation. We hypothesized that high-volume surgeons perform more complex surgeries. Therefore, we defined an Operative Complexity Index (OCI), specifically for the National Inpatient Samples (NIS) data, which provides information on in-hospital postoperative complications, to assess rates of adult spine deformity surgery (ASDS) cases as they relate to surgeon and hospital operative volume...

BACKGROUND: Cervical kyphosis may occur with neurofibromatosis type I (NF1) and is often associated with vertebral dysplasia. Outcomes of cervical spinal fusion in patients with NF1 are not well described because of the rarity of the condition. We aimed to (1) characterize the clinical presentation of cervical kyphosis and (2) report the outcomes of posterior and anteroposterior cervical fusion for the condition in these children. METHODS: The medical records and imaging studies of 22 children with NF1 who had undergone spinal fusion for cervical kyphosis (mean, 67°) at a mean age of 11 years and who had been followed for a minimum of 2 years were reviewed...
