Thoracic Bone Mineral Density measured by Quantitative Computed Tomography in Patients undergoing Spine Surgery.

Spine J 2021 May 19. Epub 2021 May 19.

Spine Care Institute, Hospital for Special Surgery, Weill Cornell Medicine, 535 East 70th St, New York, NY 10021, USA. Electronic address:

Background Context: The thoracic spine is a common location for vertebral fractures as well as instrumentation failure after long spinal fusion procedures. The association between those complications and bone mineral density (BMD) are well recognized. Due to the overlying sternum and ribs in the thoracic spine, projectional BMD assessment tools such as dual energy x-ray absorptiometry (DXA) are limited to the lumbar spine. Read More

Lateral compression type 1 (LC1) pelvic ring injuries: a spectrum of fracture types and treatment algorithms.

Eur J Orthop Surg Traumatol 2021 Apr 16. Epub 2021 Apr 16.

Department of Trauma and Orthopaedics, North Bristol NHS Trust, Southmead Hospital, Bristol, UK.

Lateral compression type 1 (LC1) fractures are the commonest pelvic ring injury. However, they represent a heterogenous spectrum of injury mechanisms and fracture patterns, resulting in a lack of strong evidence for a universally agreed treatment algorithm. Although consensus exists that LC1 fractures have a preserved posterior ligamentous complex and are vertically stable, controversy persists around defining internal rotational instability. Read More

Sacral fatigue fracture in a young girl with no history of trauma or reported athletic activity: a case report.

AME Case Rep 2020 30;4:27. Epub 2020 Oct 30.

Nomura Orthopaedic Clinic, Yamaguchi, Japan.

Sacral fatigue fractures in the young population usually occur due to repetitious physical strain from vigorous athletic activity; they are extremely rare in those younger than 13 years without intense physical activity. We report a case of sacral fatigue fracture in a healthy elementary school girl without any history of trauma or excessive athletic activity. A healthy 11-year-old girl experienced sudden low back pain upon standing after a short break in a normal running exercise for physical education at school. Read More

Dual-energy CT in musculoskeletal trauma.

Clin Radiol 2021 01 2;76(1):38-49. Epub 2020 Sep 2.

Monash Health, Dandenong Hospital, 135 David St, Dandenong, Victoria, 3175, Australia; Monash Health, Monash Medical Centre, 246 Clayton Road, Clayton, Victoria, 3168, Australia; Faculty of Medicine, Nursing and Health Sciences, Monash University, 27 Rainforest Walk, Clayton, Victoria, 3800, Australia.

Dual-energy computed tomography (DECT) combines the advantages of conventional CT with the ability to detect bone marrow oedema (BMO), which was previously limited to magnetic resonance imaging (MRI). By analysing DECT virtual non-calcium (VNCa) maps, radiologists can improve the detection of subtle and occult fractures and approximate the acuity/healing of fractures of indeterminate age. This review highlights the role of DECT in the assessment of musculoskeletal trauma, particularly among elderly, post-menopausal women and those at risk for osteoporosis. Read More

Indian J Nucl Med 2019 Oct-Dec;34(4):317-318

Department of Nuclear Medicine, Nizam's Institute of Medical Sciences, Hyderabad, Telangana, India.

Pelvic insufficiency fractures (IFs) are frequently diagnosed on technetium-99m methylene diphosphonate bone scan (BS), where it remains an important diagnostic imaging modality. Involvement of iliac bone in pelvic IFs is very rare. Differentiation from metastases is crucial where BS shows characteristic appearance obviating the need for further investigations for confirmation. Read More

Is there a significant decrease in the femoral cortical bone around Furlong stems after 18 years of follow-up?

Eur J Orthop Surg Traumatol 2020 Jan 29;30(1):117-122. Epub 2019 Aug 29.

Hospital General de Granollers, Avinguda Francesc Ribas s/n, 08402, Granollers, Barcelona, Spain.

Introduction: In the context of total hip arthroplasty (THA), there are several reasons that have motivated the development of short stems. It has been postulated that short stems allow a better conservation of the bone stock if compared to conventional stems. As far as we have knowledge, the quantitative loss of diaphyseal bone stock in patients with standard femoral stems has not been fully described. Read More
