Radiographic Outcomes of Postoperative Taping Following Hallux Valgus Correction Jan 1st, 2015

        Hallux valgus (HV) is a first ray forefoot deformity characterized by varus alignment of the first metatarsal and lateral deviation of the great toe, resulting in a medial prominence of the first metatarsal head. It often causes pain, difficulty with normal shoe wear, and loss of...

Prediction of Curve Progression in Idiopathic Scoliosis Jan 1st, 2015

        Progression of idiopathic scoliosis correlates with skeletal growth, peaks during the adolescent growth spurt, and usually stabilizes or slows at skeletal maturity. 1 The predictors of skeletal maturity guide the treatment of idiopathic scoliosis by envisaging the risk and timing of curve progression. The maturity indicators...

History of Spinal Instrumentation: The Modern Era Jan 1st, 2015

        DORSAL THORACOLUMBAR INSTRUMENTATION In 1975, the Harrington rod represented the state of the art in spinal instrumentation. The rod system, originally developed by Paul Harrington for the correction of spinal deformities, was soon used in the treatment of traumatic injuries1,2 (Fig. 3-1), degenerative disease,3 and metastatic...

Spinal Dural Arteriovenous Fistula Jan 1st, 2015

         The two most common etiologies of back pain and radiculopathy are herniation of the nucleus pulposus and degenerative changes of the spine and neuroforamen1 . Of the myriad causes of nerve compression that lead to radiculopathy, vascular etiologies remain among the most infrequent, with an estimated...

Antifibrinolytics Reduce Blood Loss in Adult Spinal Deformity Surgery Dec 31st, 2014

         Perioperative blood loss is a major concern in surgery,  particularly in complex, high-risk surgical procedures such as adult spinal deformity correction. Although recent advances including autologous blood donation, erythropoietin, and cell saver have been employed to reduce perioperative bleeding and maintain blood volume, patients nevertheless have...

A Case of Intradural Extramedullary Spinal Tuberculosis Aug 1st, 2013

Tuberculosis (TB), the disease caused by Mycobacterium tuberculosis, is the second leading killer worldwide from a single infectious agent. Spinal TB is associated with pulmonary disease and may originate from (1) hematogenous spread outside the central nervous system (CNS), (2) sites located within the cranium (meningitis), or (3) secondary extension...

Delayed Abdominal Compartment Syndrome Jun 30th, 2013

         Inroduction Abdominal compartment syndrome (ACS) is an unpredictable complication of posterior spinal fusion surgery. The condition is defined by elevated intra-abdominal compartment pressure (IAP) O 20 mm Hg, resulting in physiologic compromise and end organ dysfunction [1]. Abdominal compartment syndrome can result from trauma, extreme fluid...

Reduction of Mean Arterial Pressure at Incision Reduces Operative Blood Loss in Adolescents Jan 1st, 2013

          Surgical management of spinal deformity is associated with significant blood loss and transfusion requirements. Patient factors affecting operative blood loss include the severity and type of spinal deformity, and patient height [1-3]. Surgery-dependent factors include operative time, duration of exposure, procedure performed, surgical approach, number...

Predictors of Postoperative Infection in Spinal Deformity Surgery Jan 1st, 2013

         Despite efforts to improve infection rates, surgical site infection remains a burdensome complication of spinal surgery. Postoperative spinal wound infections lead to increased morbidity and mortality, increased hospital stay or rehospitalization, and additional cost.1 Reported rates of surgical site infection in the literature range from less...

How often is adjacent segment disease reported? Jan 1st, 2013

         Degenerative changes in the cervical spine causing symptomatic myelopathy and/or radiculopathy are common indications for anterior cervical decompression and fusion (ACDF). ACDF has a disease-free survival rate of 86% at 5 years and is considered the gold standard to treat these conditions.1 Despite the success of...

Hospital Cost Analysis of Neuromuscular Scoliosis Surgery Jan 1st, 2013

         Neuromuscular scoliosis (NMS) is commonly defined as a scoliotic deformity arising secondarily to muscle imbalance caused by an underlying neuropathic or myopathic disease. Generally, spinal deformities secondary to neuromuscular pathology present early in life and progress rapidly.1 In children and adolescents with neuromuscular disease, the incidence...

Rate of Adjacent Segment Disease Jan 1st, 2013

           Symptomatic myelopathy and/or radiculopathy are common indications for surgical intervention in the cervical spine. Anterior cervical decompression and fusion (ACDF) is considered to be the “gold standard” to treat these conditions with adjacent-level degeneration-free rates of 86% at 5 years. 1 Although successful, the incidence...

Predicting Operative Blood Loss During Spinal Fusion for Adolescent Idiopathic Scoliosis Dec 31st, 2012

         Multilevel spinal fusion has been well established as the primary approach for the surgical correction of adolescent idiopathic scoliosis (AIS).1–7 Significant intraoperative and postoperative blood loss has typically been associated with spinal fusion surgery.2,8,9 Excessive intraoperative and postoperative blood loss increases the transfusion burden on the...

Discriminative validity of the Scoliosis Research Society 22 questionnaire Jan 1st, 2012

          Introduction The treatment of adolescent idiopathic scoliosis (AIS) is based on the ability to reduce truncal deformity, limit curve progression, and improve quality of life. Because AIS does not lead to increased mortality [1], successful treatment outcomes are often dependent on improvements in healthrelated quality...

Pulmonary Recovery After Spinal Fusion for Adolescent Idiopathic Scoliosis Jan 1st, 2011

          The use of anterior approaches for spinal fusion for the treatment of adolescent idiopathic scoliosis (AIS) has been debated because of the concern that pulmonary function is compromised with procedures that violate the chest wall. Although both anterior and posterior spinal approaches have been indicated...

Anterior Spinal Fusion for Thoracolumbar Scoliosis Jan 1st, 2010

           Anterior spinal approaches have been indicated for thoracolumbar curves in adolescent idiopathic scoliosis (AIS).1,2 These approaches facilitate large coronal curve correction and derotation, short segment fusions, saving of distal levels, and reduced operative blood loss. Recent evidence suggests, however, that approach-related pulmonary function impairment may...

Bone grafting options for lumbar spine surgery: a review examining clinical efficacy & complications Jan 1st, 2010

            The choice of bone graft for lumbar spinal arthrodesis takes many factors into consideration.
