We present a case of apparently uncomplicated lumbar decompression and discectomy with delayed postoperative neurological deterioration secondary to subdural hematoma at the thoracolumbar level of the spinal cord. Previously described subdural hematomas have occurred spontaneously or related to iatrogenic injury. Hitherto, no case of acute postoperative subdural hematoma has been reported in the postoperative setting in the absence of known iatrogenic dural injury. A 76-year-old male with central and lateral recess spinal stenosis underwent apparently uncomplicated bilateral L3-4 and left sided L4-5 decompressive partial laminectomies and discectomy...

A 61-year-old gentleman was admitted with progressive symptoms of cervical myelopathy. An MRI performed showed severe compression from C3-6 with cord signal changes. He was offered surgical intervention but the operation had to be delayed because of worsening abdominal distension. X-rays performed showed a severely dilated colon measuring >12 cm. A CT did not show any obstructive cause. He was managed conservatively for more than 2 weeks but did not improve. As his symptoms continued to worsen, a decision was made to proceed with a C3-6 posterior decompression and fusion, despite the theoretical risk of bacterial translocation predisposing him to infection...

Extra-skeletal Ewing sarcoma in pregnancy is rare. There is thus limited scientific evidence to guide clinicians in its complicated management, particularly within the context of early gestation. We therefore share our successful outcome in a 32-year-old pregnant patient, following a unique management strategy of complete aggressive surgical resection prior to neo-adjuvant therapy. The case involved a 2-month history of right-sided back and gluteal pain, with associated paraesthesia. Lumbosacral magnetic resonance imaging (MRI) revealed an approximate 40×50 mm indeterminate mass in the lower right paraspinal musculature...

Polyaxial screw head dislocation in the absence of a manufacture defect is extremely rare and represents a biomechanical overload of the screw, leading to early failure. A 58-year-old gentleman underwent instrumented fusion using polyaxial pedicle screws-titanium rod construct with interbody cage for spondylolytic spondylolisthesis at the L5/S1 level. He attempted to bend forward ten days after the surgery which resulted in a dislocation of the right S1 polyaxial screw head from the screw shank with recurrence of symptoms...

Lumbar disc herniation is common and may be symptomatic. The magnetic resonance imaging (MRI) scan is an appropriate tool to confirm the diagnosis and affected level of the spine. While a disc herniation is usually associated with ipsilateral symptoms, a few cases have been reported to present with contralateral symptoms. We report a unique case of left lumbar disc herniation at L5/S1 who presented with contralateral symptoms and was successfully treated with a right L5/S1 foraminal block. However, the patient developed concordant ipsilateral symptoms 6 weeks later and was treated with left L5/S1 microdiscectomy...

Distal junctional failure (DJF) with fracture at the last instrumented vertebra is a rare occurrence. In this case report, we present two patients with L5 vertebral fracture post-instrumented fusion of the lumbar spine. The first patient is a 78-year-old female who had multi-level degenerative disc disease, spinal stenosis and degenerative scoliosis involving levels T12 to L5. She underwent instrumented posterolateral fusion (PLF) from T12 to L5, and transforaminal lumbar interbody fusion (TLIF) at L2/3 and L4/5...

Traumatic cervical severe spondylolisthesis is a rare and severe lesion which is typically associated with a spinal cord injury. Nevertheless, it occasionally has a pauci-symptomatic course which may delay its diagnosis. The authors report an exceptional case of a 33-year-old woman who had mild spasticity in her lower limbs and neck pain 9 months after a traffic accident. The computed tomographic scan and magnetic resonance image revealed C7-T1 grade III spondylolisthesis and spinal cord signal change. The initial cervical traction did not obtain a spinal realignment...

This case report describes the first case of a bone bridge formation across the left L5/S1 neuroforamen after instrumented posterolateral fusion for L5/S1 isthmic spondylolisthesis. Our patient was a 70-year-old lady who had grade 2, L5/S1 isthmic spondylolisthesis and bilateral S1 nerve root compression. She suffered from mechanical low back pain and neurogenic claudication, with radicular pain over both S1 dermatomes. She underwent in-situ, instrumented, posterolateral fusion and was asymptomatic for more than 13 years before developing progressive onset of left radicular pain over the L5 dermatome...

Between the 80% and 90% of vertebral fractures in over 65 years people are due to osteoporosis. Over the 30% of patients affected by vertebral osteoporosis fractures needs of surgical treatment and the 12% presents complications requiring an invasive surgical approach. We report an unusual case of spontaneous corpectomy and anterior arthrodesis occurred in a patient suffering from Ankylosing Spondylitis. This event invites us to reflect about the magnitude of the biological power of the bone healing, even in adverse conditions...

Various minimally invasive techniques have been reported as an alternative to conventional lumbar decompression. The major advantage of these minimally invasive procedures lies in their reduction of unnecessary exposure and tissue trauma. Our objective was to describe a minimally invasive procedure for lumbar spinal stenosis decompression by enlarging the lumbar interspinous space, approaching it with a tubular retractor, and assisting with microscopy. Thoracolumbar fascia and paravertebral muscles are preserved throughout the whole procedure...

REVIEW
Jessica Figueroa, John G DeVine
Review the current literature regarding spontaneous spinal epidural hematomas (SSEHs) and report on the known risk factors, evaluation, and treatment of this rare entity. A literature search was performed using PubMed and Ovid to identify articles pertaining to SSEHs. Due to the rarity of the pathologic entity, only scattered case reports and associated reviews are available. SSEHs are a rare yet potentially life-altering event. The underlying risk factors are poorly understood, and SSEHs present with minimal or no antecedent trauma...

BACKGROUND: Spinal fusion surgery for the treatment of adolescent idiopathic scoliosis (AIS) is increasing. Health systems and surgeons are decreasing hospital length of stay (LOS) to decrease costs. The purpose of this study was to review the contribution of an accelerated discharge protocol on the total cost of a single episode of care related to the surgical treatment of AIS at a single institution. METHODS: A retrospective cost analysis was performed over an 18-month period, from January 2014 through June 2015, before and after the institution of an accelerated discharge program...

BACKGROUND: Growing scrutiny has placed hospitals at the center of readmission prevention. The relationship between pre-operative employment status, length of hospital stays (LOS) and 30-day readmission rates after elective spine surgery remains unclear. METHODS: The medical records of 360 patients (employed: n=174, unemployed: n=70, retired: n=40, disabled: n=76) undergoing elective spine surgery at a major academic medical center were reviewed. Patient demographics, comorbidities, and post-operative complication rates were recorded...

BACKGROUND: Surgical treatment for lumbar disc herniation consists of discectomy performed either open or minimally invasive techniques. Endoscopic discectomy using the tubular retractor is been increasingly used as it gives advantage of smaller incision, less tissue injury and faster recovery. The aim of this study was to check its feasibility and learning curve at a tertiary public sector hospital with a large volume load (more than 50 spine surgeries per month) with treatment provided free of cost...

BACKGROUND: While there are variations in techniques and surgical approaches to spinal fusion, there is not a defined consensus on a recommended surgical approach. The aim of this study is to determine if there was a difference in intra- and post-operative complication rates between different surgical approaches after elective spinal fusion (≥3 levels) for adult spine deformity. METHODS: The medical records of 443 adult spine deformity patients undergoing elective spinal fusion (≥3) at a major academic institution from 2005 to 2015 were reviewed...

BACKGROUND: Pre-operative spine level localization by palpation of anatomical landmarks (ribs, spinous processes) in posterior approaches for surgeries from T4 to L2 is often inaccurate. This can lead to ineffective utilization of procedural time, increased radiation dose, potentially longer skin incision and wrong level surgery. Factors affecting topographical accuracy includes body mass index (BMI) of the patient, congenital or acquired deformity and knowledge of topographical anatomy...

BACKGROUND: Minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) has become one of the standard techniques for approaching ipsilateral decompression, anterior column fusion, and posterior stabilization. This procedure is usually accompanied by the placement of bilateral transpedicular screws in the corresponding segment. The purpose of this study was to evaluate the clinical efficacy of unilateral screw fixation compared with bilateral fixation in patients diagnosed with low-grade symptomatic lumbar spondylolisthesis who underwent an MI-TLIF technique...

BACKGROUND: Surgical interventions such as posterior lumbar interbody fusion (PLIF) with and without posterior instrumentation are often employed in patients with degenerative spinal conditions that fail to respond to conservative medical management. The VariLift(®) Interbody Fusion System was developed as a stand-alone solution to provide the benefits of an intervertebral fusion device without the requirement of supplemental pedicle screw fixation. METHODS: In this retrospective case series, 25 patients underwent PLIF with a stand-alone VariLift(®) expandable interbody fusion device without adjunctive pedicle screw fixation...
