Symptomatic lumbar disc herniations (LDH) are very common. LDH resorption may occur by a "self-healing" process, however this phenomenon remains poorly understood. By most guidelines, if LDH remains symptomatic after 3 months and conservative management fails, surgical intervention may be an […]

A 49-year-old man presented with right foot drop, bilateral cruralgia mainly on the left side, and genital and perianal hypoesthesia, which started suddenly 12 days before. After onset of symptoms, the patient also experienced an accidental fall at home, resulting in a left fibular fracture, which […]

Delirium tremens is a symptom of alcohol withdrawal syndrome that occurs 48 to 96 hours after the last drink in 5% of withdrawing patients./r/nThis report describes the clinical progression of a case of lumbar vertebral burst fracture with alcohol withdrawal delirium that was difficult to […]

We present the case of a patient diagnosed with ankylosing spondylitis (AS) along with Kikuchi-Fujimoto disease (KFD), possibly triggered by infection or autoimmunity. Both AS and KFD involved a similar immune pathway. Hence, clinicians should consider the possibility of KFD when lymphadenopathy is […]

Sensory ataxia due to posterior cord syndrome is a relevant, disabling condition in nontraumatic spinal cord dysfunction. Ataxic gait is a common symptom of sensory ataxia that restricts activities of daily living. A 70-year-old woman with severe sensory disturbance was diagnosed with intradural […]

Laminoplasty is a common treatment for cervical spondylotic myelopathy (CSM) and for ossification of the posterior longitudinal ligament (OPLL). However, approximately 21% of patients undergoing laminoplasty develop cervical kyphotic deformity (KD). Because of the high prevalence rate of KD, […]

Spinal robotics for thoracolumbar procedures, predominantly employed for the insertion of pedicle screws, is currently an emerging topic in the literature. The use of robotics in instrumentation of the cervical spine has not been broadly explored. In this review, the authors aimed to coherently […]

Tracheal stenosis and tracheomalacia in patients with congenital scoliosis are serious and rare conditions caused by congenital dysplasia, postintubation injury, trauma, and tracheal tumor. Anesthesia of a child with tracheal stenosis is challenging for anesthesiologists. We describe an 8-year-old […]

De Novo Spinal Infections: Where Are We Now? - Jonathan Plümer, MD, PhD

Some major regulatory announcements took centre stage in our most read articles of December, with the top story revealing that the Swiss Federal Assembly had voted in favour of accepting medical devices with US Food and Drug Administration (FDA) marketing authorisation. This was closely followed by […]

Lateral Lumbar Corpectomy Tips and Tricks - Rod J. Oskouian, Jr , M.D.

Hip-spine syndrome is a complex challenge for orthopedic surgeons. We present a 60-year-old female with a history of spinal fusion and total hip arthroplasty. The patient underwent extension of the previous fusion with sacropelvic fixation, and 5 months later she presented with left posterior […]

The aim of this case report is to show that late diagnosis of vertebral osteoid osteoma gives rise to structural scoliosis which sometimes requires long-term management./r/nWe report a case of an osteoid osteoma in the thoracic spine associated with structural scoliosis. We describe a 14-year-old […]

A 70-year-old woman presented with severe trunk deformity, gait disturbance, and bilateral hip pain. Radiography and magnetic resonance imaging revealed severe spinal kyphosis, bilateral osteoarthritis of the hip joints, and lumbar canal stenosis. A 2-stage corrective surgery for the treatment of […]

The clinical outcomes of single-level anterior cervical discectomy and fusion (ACDF) with the Zero-profile (Zero-p) were evaluated in comparison with the anterior cervical cage-plate construct (CPC)./r/nWe performed a systematic search covering PubMed, Embase, Cochrane Central Register of […]

We report the strategy of anesthesia and intraoperative neurophysiological monitoring (IONM) in a 29-year-old, 22 weeks pregnant patient posted for surgery for aggressive vertebral body hemangioma. We used propofol and fentanyl-based anesthesia for IONM. Motor-evoked potentials (MEP) and […]

December 2022 You can now choose what you want to see on your myAO feed! In this month's update you will find a new feed design and experience divided into network activity and knowledge updates. The post New in December – A new feed experience appeared first on myAO.

Taking top spot in our most read Top 10 for November was a comment piece by Brian Fiani (New York, USA), who examined the role of minimally invasive surgery in patients with spinal deformity. Rounding out the top three were the one-year data from the TOPS IDE trial and the launch of a new tube […]

An estimated 45% of concussions are reported to be related to motor vehicle collisions (MVC). However, limited research exists involving the treatment of MVC-related concussion, especially when combined with whiplash-associated disorders (WAD). Purpose: The purpose of this case series is to […]

Ankylosing spondylitis (AS) is a seronegative arthropathy which results in pathological ossification of the ligaments, disc, endplates and apophyseal structures. Cervical spinal fractures are more common in patients with ankylosing spondylitis than in patients without ankylosing spondylitis due to […]

Proximal junctional kyphosis (PJK) is one main complication in the surgical treatment of adult spinal deformities. Ending within the thoracolumbar junction (TLJ) should but cannot always be avoided to reduce the risk for PJK. With this systematic review we sought to define the most preferable […]

The prevalence of pain after treatment of a spinal intradural tumor is remarkably high, approximately up to 40% of the patients suffer from central neuropathic pain. Publications on spinal cord stimulation (SCS) and its effect on pain caused by intradural spinal tumors are rare. We discuss the case […]

In minimally invasive spinal surgery, the treatment of lumbar spinal stenosis with microendoscopic discectomy (MED) or unilateral biportal endoscopic discectomy (UBED) shows effective results, but which is more effective is controversial. Our study aimed to evaluate the efficacy and safety of UBED […]

This systematic review, meta-analysis and meta-regression investigated the effects of individualized interventions, based on exercise alone or combined with psychological treatment, on pain intensity and disability in patients with chronic non-specific low-back-pain. Databases were searched up to […]

Traumatic facet dislocations in the subaxial cervical spine, also known as locked facets, are commonly associated with neurological deficits. The fear of the presence of an associated traumatic disc herniation and consequent neurological worsening usually causes a delay in the spinal realignment. […]

 In this study, we systematically analyze the effectiveness of the uniportal full-endoscopic (UPFE) and minimally invasive (MIS) decompression for treatment of lumbar spinal stenosis patients./r/n We performed a systematic search in Medline, Embase, Europe PMC, PubMed, Web of Science, Cochrane […]

Robotic surgery (RS) may offer benefits compared with freehand/conventional surgery (FS) in the treatment of patients with spinal disease. The aim of this study was to evaluate the efficacy and safety of RS versus FS in spinal fusion./r/nA systematic review and meta-analysis was performed. Data […]

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 […]

Vertebral compression fractures caused by osteoporosis are common in elderly patients and are often encountered by clinical physicians. Percutaneous balloon kyphoplasty (PKP) is widely accepted as a minimally invasive procedure for effectively relieving pain and correcting deformities, but […]

We present a 36-year-old man with L1 burst fracture after a sneeze. He was in follow-up for indolent systemic mastocytosis (ISM), and osteoporosis was treated with bisphosphonate. Owing to neurologic impairment, posterior decompressive laminectomy and thoraco-lumbar fusion with cemented screws were […]
