Biomechanics of Femoral Neck Fractures and Implications for Fixation.

J Orthop Trauma 2019 Jan;33 Suppl 1:S27-S32

*Institute for Biomechanics, BG Unfallklinik Murnau, Murnau, Germany; and †Institute for Biomechanics, Paracelsus Medical University Salzburg, Salzburg, Austria.

Fractures of the femoral neck can occur in young healthy individuals due to high loads occurring during motor vehicle accidents, impacts, or falls. Failure forces are lower if impacts occur sideways onto the greater trochanter as compared with vertical loading of the hip. Bone density, bone geometry, and thickness of cortical bone at the femoral neck contribute to its mechanical strength. Read More

J Pediatr Orthop 2019 Jan;39(1):e12-e17

Children's Healthcare of Atlanta.

Introduction: The insertion of 2 elastic stable intramedullary nails (ESINs) is a common treatment for pediatric femur fractures. However, the use of this technique in length-unstable or metadiaphyseal fractures has historically been associated with higher complication rates. To improve stability, the addition of a third ESIN has been assessed biomechanically and clinically, but the addition of a fourth nail has only been evaluated biomechanically. Read More

Anatomic Single-Incision Repair of Distal Biceps Tendon Ruptures Using Intramedullary Soft Anchors.

Arthrosc Tech 2018 Nov 22;7(11):e1177-e1180. Epub 2018 Oct 22.

Advanced Orthopaedics and Sports Medicine, San Francisco, California, U.S.A.

Distal biceps tendon ruptures are uncommon injuries responsible for only 3% of all injuries to the biceps tendon. For most of these cases, unless the patient is elderly or infirm, conservative management should be avoided and the injury should be treated with a surgical procedure to reattach the bicep tendon to the radial tuberosity. In this Technical Note and accompanying video, we describe an anatomic single-incision technique using 2 intramedullary soft anchors, which decreases the likelihood of complications associated with bicortical drilling and metal suspensory fixation.

Evidence-based update on the surgical treatment of pediatric tibial shaft fractures.

Curr Opin Pediatr 2018 Nov 15. Epub 2018 Nov 15.

Pediatric Orthopaedic Surgery Service, Hospital for Special Surgery, Weill Cornell Medical College, New York, New York, USA.

Purpose Of Review: To describe surgical treatment options for pediatric tibial shaft fractures which are the third most common pediatric long bone fracture. Management of these injuries is dictated by fracture location, fracture pattern, associated injuries, skeletal maturity, and other patient-specific factors. Although most pediatric tibial shaft fractures can be treated nonoperatively, this review provides an update on surgical treatment options when operative intervention is indicated. Read More

Intramedullary Spinal Cord Lipoma Mimicking a Late Subacute Hematoma.

Asian J Neurosurg 2018 Oct-Dec;13(4):1282-1284

Department of Neurosurgery, University Hospital Center Zagreb, University of Zagreb, School of Medicine, Zagreb, Croatia.

Spinal cord lipomas are rare and benign tumors which may cause progressive neurological deficits due to their local expansion. We present the case of a 59-year-old male patient with severe lumbosacral pain and slowly progressive paresis of the right leg, misdiagnosed with degenerative spine disease. Repeated magnetic resonance (MR) T1-weighted images of the thoracic spine suggested a subacute intramedullary hematoma. Read More

Intramedullary Glioblastoma Multiforme of Spine with Intracranial Supratentorial Metastasis: Progressive Disease with a Multifocal Picture.

Asian J Neurosurg 2018 Oct-Dec;13(4):1209-1212

Department of Radiology, Army Hospital Research and Referral, New Delhi, India.

Primary spinal glioblastoma multiforme (GBM) is very uncommon while an intramedullary spinal GBM with intracranial metastasis is rarely heard of. A 23-year-old male presented with bilateral paraplegia associated with bowel and bladder incontinence. Craniospinal radiograph showed an intramedullary spinal mass lesion, for which he underwent laminectomy and histopathology revealed GBM. Read More
