David Yen, Abdu Albargi
BACKGROUND: At our centre, laminectomies have been traditionally performed as inpatient surgery. A gradual change in practice occurred between 2010 and 2013 to try to do these procedures as outpatient or overnight stay surgery. METHODS: We conducted a retrospective cohort study of consecutive patients having laminectomies over 2 18-month periods: before the change in practice and after full implementation of the outpatient/overnight stay protocol. We collected information on patient characteristics (age, sex, American Society of Anesthesiologists [ASA] classification, home address, number of laminectomy levels, estimated blood loss) and patient outcome (complications, hospital length of stay, 30-day readmissions)...

OBJECTIVE: To evaluate the outcome of bone metabolism and bone mineral density (BMD) in haemodialysis patients after parathyroidectomy (PTX). METHODS: A total of 31 haemodialysis patients with secondary hyperparathyroidism (SHPT) were treated with PTX. BMD of lumbar spine (LS) and femoral neck (FN) was determined by dual energy X-ray absorptiometry. RESULTS: Parathyroidectomy ledds to significant decrease of serum β-crosslaps (β-CTX), osteocalcin (OC) and procollagen type I amino-terminal propeptide (PINP) while serum sclerostin (SOST) increased after surgery...

Surgical correction of fixed thoracolumbar deformity is usually achieved by estimating the preoperatively planned correction angles during surgery and is therefore prone to inaccuracy. This is particularly problematic in biplanar deformities. To overcome these difficulties, 3D model for planning, preparation, and simulation of an asymmetric pedicle subtraction osteotomy (aPSO) was printed and used to realign coronal and sagittal balance in case of rigid degenerative kyphoscoliosis. A 59-year-old woman presented with severe back pain and spinal claudication and was diagnosed with a rigid kyphoscoliosis with multilevel spinal stenosis...

INTRODUCTION: Complex regional pain syndrome (CRPS) is a major complication after trauma, surgery, and/or immobilization of an extremity. The disease often starts with clinical signs of local inflammation and develops into a prolonged phase that is characterized by trophic changes and local osteoporosis and sometimes results in functional impairment of the affected limb. While the pathophysiology of CRPS remains poorly understood, increased local bone resorption plays an undisputed pivotal role...

BACKGROUND: The anterior approach to lumbar spine surgery has grown in popularity in the past few years; spinal fusion of the last two lumbar levels is often required. While there are alternatives to bone grafting available, including recombinant human bone morphogenetic protein 2 or bone substitutes, only cancellous autologous bone has all the required factors for bone growth. To avoid the use of bone substitutes, remote iliac crest bone harvesting remains the gold standard. However, this technique may lead to some unfavorable outcomes...

BACKGROUND: Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys are used to assess the quality of the patient experience following an inpatient stay. HCAHPS scores are used to determine reimbursement for hospital systems and incentivize spine surgeons nationwide. There are conflicting data detailing whether early readmission or other post-discharge complications are associated with patient responses on the HCAHPS survey. Currently, the association between post-discharge ED visits and HCAHPS scores following lumbar spine surgery is unknown...

BACKGROUND CONTEXT: Surgical treatment for unstable atlas fractures has evolved in recent decades from C1-C2 or C0-C2 fusion to motion-preservation techniques of open reduction and internal fixation (ORIF). However, regardless of transoral or posterior approach, the reduction is still not satisfactory. PURPOSE: The article describes and evaluates a new technique for treating the unstable atlas fractures by using a monoaxial screw-rod system. STUDY DESIGN: This is a retrospective study PATIENT SAMPLE: The sample includes adult patients with unstable C1 fractures treated with a posterior monoaxial screw-rod system...

REVIEW
Qiming Xu, Nan Wu, Lijia Cui, Zhihong Wu, Guixing Qiu
Filamin B (FLNB) is a large dimeric actin-binding protein which crosslinks actin cytoskeleton filaments into a dynamic structure. Up to present, pathogenic mutations in FLNB are solely found to cause skeletal deformities, indicating the important role of FLNB in skeletal development. FLNB-related disorders are classified as spondylocarpotarsal synostosis (SCT), Larsen syndrome (LS), atelosteogenesis (AO), boomerang dysplasia (BD), and isolated congenital talipes equinovarus, presenting with scoliosis, short-limbed dwarfism, clubfoot, joint dislocation and other unique skeletal abnormalities...

BACKGROUND: Pseudomeningocele is an uncommon but problematic complication in lumbar spine surgery. Initial conservative measures are frequently successful but persistence requires additional management. The current surgical approach can involve a range of techniques, including blood patches, hydrogel/fibrin sealants, drains, open surgical repair of the dura or a combination of the above if symptoms persist. This report demonstrates a novel technique for repair using a percutaneous approach to deliver an autologous fat graft into the pseudomeningocele...

PURPOSE: Spine surgery still remains a challenge for every spine surgeon, aware of the potential serious outcomes of misplaced instrumentation. Though many studies have highlighted that using intraoperative cone beam CT imaging and navigation systems provides higher accuracy than conventional freehand methods for placement of pedicle screws in spine surgery, few studies are concerned about how to reduce radiation exposure for patients with the use of such technology. One of the main focuses of this study is based on the ALARA principle (as low as reasonably achievable)...
