BACKGROUND CONTEXT Spine surgeons employ a high volume of imaging in the diagnosis and evaluation of spinal pathology. However, little is known regarding patients' knowledge of the radiation exposure associated with these imaging techniques. PURPOSE To characterize spine patients' knowledge regarding radiation exposure from various imaging modalities. (More)
Ankle fractures are common injuries frequently treated by foot and ankle surgeons. Therefore, it has become a core competency for orthopedic residency training. Surgical educators must balance the task of training residents with optimizing patient outcomes and minimizing morbidity and mortality. The present study aimed to determine the effect of resident(More)
Bone morphogenetic protein (BMP) utilization as an adjunct for spinal arthrodesis has gained considerable momentum among spine surgeons. Despite carrying Food and Drug Administration approval for only single level anterior lumbar interbody fusion from L4-S1, the majority of BMP administration is in "off label" settings. Over the last decade, BMP utilization(More)
This study explored three dimensional (3D) talonavicular joint (TNJ) coverage/orientation and bone morphology to reveal parameters that could classify and identify predispositions to cavus and planus feet. 3D models of 65 feet from 40 subjects were generated from computed tomography images classified as pes cavus, neutrally aligned, or(More)
Superior mesenteric artery (SMA) syndrome is a rare and potentially life-threatening complication of scoliosis surgery. The anatomical relationship of the duodenum and the superior mesenteric artery, the correction of angular deformity of the spine, and the normal adolescent growth spurt all contribute to the condition. We report the case of a 14-year-old(More)
STUDY DESIGN Retrospective imaging review. OBJECTIVE Utilize magnetic resonance imaging (MRI) to expand the anatomical description of psoas morphology and its association with neurovascular structures at L4-5. SUMMARY OF BACKGROUND DATA Anatomical psoas muscle variants may present a greater risk of neurovascular injury at the L4-5 level during lateral(More)
BACKGROUND CONTEXT Although lumbar spinal stenosis often presents as a degenerative condition (degenerative stenosis [DS]), some patients present with symptoms from lifelong narrowing of the spinal canal. These patients have congenital stenosis (CS) and present with symptoms of stenosis at a younger age. Patients with CS often have a distinct(More)
BACKGROUND Severe postoperative knee contractures after arthroplasty or megaprosthesis reconstruction occur rarely, but are devastating complications. Management of preoperative flexion contractures is well-described, but there is a paucity of literature for surgical treatment of postoperative contractures. A retrospective chart review was performed for a(More)
STUDY DESIGN Retrospective analysis of a prospectively maintained surgical registry. OBJECTIVE To compare postoperative narcotic consumption between multimodal analgesia (MMA) and patient-controlled analgesia (PCA) after an anterior cervical discectomy and fusion (ACDF). SUMMARY OF BACKGROUND DATA Studies suggest that a multimodal approach to pain(More)
BACKGROUND Synovial chondromatosis (SCh) can undergo malignant transformation. Pathologic diagnosis of secondary synovial chondrosarcoma (SChS) is challenging and misdiagnosis may result in over- or undertreatment. METHOD A systematic review revealed 48 cases of SChS published in 27 reports since 1957. Data was collected to identify findings indicative of(More)
