Adult spinal deformity (ASD) is usually rigid and requires a combined anterior-posterior approach for deformity correction. Anterior lumbar interbody fusion (ALIF) allows direct access to the disc space and placement of a large interbody graft. A larger interbody graft facilitates correction of […]

Ten days after L3-L5 instrumented posterior lumbar spinal fusion, an 85-year-old woman developed Grade 4 spondylolisthesis at L5-S1 after a minor fall. She underwent posterior open reduction and internal fixation with extension of fusion from L2 to the pelvis. The preexisting hardware at L5 caused […]

Vascular injury is a serious complication during lumbar fusion surgery, leading to massive blood loss and life-threatening circulatory failure. In this study, we report on a patient with abdominal aorta injury at L2-L3 level during lumbar fusion surgery via posterior approach. Fortunately, our […]

Rehabilitation of patients with high cervical spinal cord injury (CSCI) to improve activities of daily living (ADL) is challenging due to severe paralysis. In addition, pediatric patients with CSCI are rare, and literature describing ADL changes as the patient grows are limited. In this case […]

Giant cell tumor (GCT) of bone is essentially benign but locally aggressive, and the rate of local recurrence is high when the resection is not enough. En bloc resection is recommended as an ideal solution for GCT to decrease the risk of local recurrence, but it remains challenging for cervical […]

Early-onset scoliosis (EOS) is a spinal deformity affecting children under the age of 10. Understanding the impact of EOS on quality of life can be achieved through appropriate patient/carer-reported outcome measures (PROMs). The aim of this systematic review was to identify, evaluate and summarize […]

A 45-year-old woman had a grade II chondrosarcoma (T2N0M0G2) located at the spinous processes and laminas of T3-6 with the tumor extension into the spinal canal at T3-4. To perform en bloc tumor resection, we released or disarticulated bilateral costovertebral ligaments from T3-6 and cut the […]

We report a case of a 67-year-old male patient who underwent a C1 laminectomy with laminoplasty at C2-3 because of cervical ossification of the posterior longitudinal ligament. At 6 weeks after surgery, neck pain occurred after minor trauma without neurological deterioration. Computed tomography […]

Predicting Spine Instrumentation Failure After Adult Deformity Surgery - Noojan Kazemi, M.D. & UAMS

September 2022 Children may experience several types of pediatric spinal deformity, including scoliosis, kyphosis and spondylolisthesis. While many pediatric spinal deformities can be treated conservatively, with physical therapy or bracing, some require surgery. The post myAO Clinical Roundup on […]

Aging is universal. Both osteoporosis and the bone fractures that occur as a result of osteoporosis become more likely with age. Current clinical guidelines do not recommend bed rest during treatment for osteoporotic vertebral fractures—spinal fractures that occur in bones that has been weakened […]

In chronic LBP (CLBP), guideline-endorsed treatment is to stay active, return to normal activity, and to exercise. Several reviews on various exercise types used in CLBP have been published. We aimed to identify systematic reviews of common exercise types used in CLBP, to appraise their quality, […]

Spinal cord injury without radiographic abnormality (SCIWORA) is defined as having "clinical symptoms of traumatic myelopathy with no radiographic or computed tomographic features of spinal fracture or instability". The mechanism of pediatric SCIWORA following minor trauma is still unclear. Tight […]

This report details the cases of 2 older male patients with ankylosing spondylitis (AS) who presented with lumbar spinal stenosis at a single residual mobile segment and were treated with decompression without fusion. Both patients presented with severe symptoms in their lower limbs and opted to […]

Spondylodiscitis accompanying spinal epidural abscess is often treated with decompression surgery when there are neurological symptoms. We report a case of spondylodiscitis accompanying spinal epidural abscess with severe lower extremity pain that was successfully treated with percutaneous […]

 We present the case of an intracranial subdural hygroma resulting from intraoperatively undetected dural tear after unilateral biportal endoscopic (UBE) spine surgery for lumbar spinal stenosis./r/n An 80-year-old woman presented with insidious onset, gradually progressing low back pain, and […]

Lumbar spinal canal stenosis (LSS) is a common spinal disorder among older people. Some LSS patients say that their pain worsens when they lift heavy objects. The Valsalva maneuver is the optimal breathing pattern for producing maximal force. Herein, we present two cases of LSS where the movement […]

Rapidly Destructive Osteoarthritis (RDOA) has been described for the hip and shoulder joints and is characterized by a quickly developing bone edema followed by extensive remodeling and joint destruction. Confronted with a similarly evolving case of endplate edema and destruction of the disk […]

A 5-year-old boy had a thoracolumbar-level MMC that had been repaired at the day after birth and kyphotic deformity got worse as he grew. He complained of discomfort about not being able to take a supine posture and decided to perform surgery for kyphosis. In our case, surgical correction is […]

Sacroiliac (SI) joint pain causes significant disability and impairment to quality of life (QOL). Minimally invasive SI joint fusion is increasingly used to relieve chronic SI joint pain among patients who do not respond to nonsurgical treatment./r/nTo systematically review the existing literature […]

Systematic review./r/nThe aim of this review is to present an overview of robotic spine surgery (RSS) including its history, applications, limitations, and future directions./r/nThe first RSS platform received United States Food and Drug Administration approval in 2004. Since then, robotic-assisted […]

Pectus excavatum is the most common congenital chest wall defect. Thoracolumbar spinal stenosis and kyphoscoliosis was seen in patients with pectus excavatum. It can be caused by ossification of the ligamentum flavum, which is rare in patients with pectus excavatum./r/nWe reported a 26-year-old […]

July 2022 This month's myAO update is all about your feed. From better customization to improvements on video discovery, we've been hard at work with some smart additions that make the most popular part of the app even better. The post myAO customized feed appeared first on myAO.

AlloFuse micro fibres (AlloSource) AlloSource has announced the addition of AlloFuse micro fibres demineralised bone allograft for use in spinal, foot and ankle or other orthopaedic procedures. The micro fibres are made of 100% demineralised cortical bone and do not contain any form of carrier. The […]

Vertebral compression fracture (VCF) is one of the most common diseases in spinal surgery. Traditional percutaneous vertebroplasty (PVP) under fluoroscopy is an effective method to treat vertebral compression fracture. However, there is still a risk of vascular nerve injury and infection caused by […]

Intraoperative Use of Ultrasound in Spine Surgery – Kenneth Crandall, MD

Osteoporotic hyperkyphosis is associated with adverse outcomes, such as fatigue, back pain, or reduced back extensor strength, with a negative impact on functionality and quality of life. The purpose of this review is to assess the effectiveness of spinal orthosis on these adverse effects. A […]

This study aimed to conduct a systematic review and meta-analysis to assess the risk factors for proximal junctional kyphosis after the correction surgery of adult spinal deformity./r/nRelevant studies were systematically retrieved from databases including Cochrane Library, PubMed, and Embase. […]

In vitro testing has been conducted to provide a comprehensive understanding of the biomechanics of the cervical spine. This has allowed a characterization of the stability of the spine as influenced by the intrinsic properties of its tissue constituents and the severity of degeneration or injury. […]

No clear consensus exists on which anterior surgical technique is most cost-effective for treating cervical degenerative disk disease (CDDD). One of the most common treatment options is anterior cervical discectomy with fusion (ACDF). Anterior cervical discectomy with arthroplasty (ACDA) was […]
