Additional clinical value of routine CT imaging in fragility fractures of the pelvis: a prospective cohort study (ARTIFACT).

Eur J Trauma Emerg Surg 2022 May 20. Epub 2022 May 20.

Department of Trauma Surgery, Northwest Clinics Alkmaar, Alkmaar, The Netherlands.

Purpose: Additional CT imaging for fragility fractures of the pelvis (FFP) has a high detection rate for concomitant posterior ring fractures (cPRFs). However, the clinical value of routine additional CT imaging is unknown. This study aimed to determine the additional clinical value of routine CT imaging by changes in treatment policy and to establish the predictive value of pain localized around the sacroiliac joint (SIJ) for cPRFs.

Effect of osteoporosis-related reduction in the mechanical properties of bone on the acetabular fracture during a sideways fall: A parametric finite element approach.

PLoS One 2022 7;17(2):e0263458. Epub 2022 Feb 7.

Research Unit of Medical Imaging, Physics, and Technology, University of Oulu, Oulu, Finland.

Purpose: The incidence of acetabular fractures due to low-energy falls is increasing among the geriatric population. Studies have shown that several biomechanical factors such as body configuration, impact velocity, and trochanteric soft-tissue thickness contribute to the severity and type of acetabular fracture. The effect of reduction in apparent density and elastic modulus of bone as well as other bone mechanical properties due to osteoporosis on low-energy acetabular fractures has not been investigated.

Emergency Department Stress Radiographs of Lateral Compression Type-1 Pelvic Ring Injuries Are Safe, Effective, and Reliable.

J Bone Joint Surg Am 2022 02;104(4):336-344

Department of Orthopaedic Surgery, University of Utah, Salt Lake City, Utah.

Background: Occult instability of lateral compression type-1 (LC1) pelvic ring injuries may be determined with a fluoroscopic stress examination under anesthesia (EUA) performed in the operating room. We hypothesized that LC1 injuries, similar to some fractures of the extremities, could be radiographically stressed for stability in the emergency department (ED). Our primary objective was to determine if stress examination of LC1 fractures could be safely and accurately performed in the ED and could be tolerated by patients. Read More

Teriparatide and stress fracture healing in young adults (RETURN - Research on Efficacy of Teriparatide Use in the Return of recruits to Normal duty): study protocol for a randomised controlled trial.

Trials 2021 Aug 30;22(1):580. Epub 2021 Aug 30.

Norwich Medical School, Faculty of Medicine and Health Sciences, University of East Anglia, Norwich, NR4 7TJ, UK.

Background: Stress fractures are a common and potentially debilitating overuse injury to bone and occur frequently among military recruits and athletes. Recovery from a lower body stress fracture typically requires several weeks of physical rehabilitation. Teriparatide, a recombinant form of the bioactive portion of parathyroid hormone (1-34 amino acids), is used to treat osteoporosis, prevent osteoporotic fractures, and enhance fracture healing due to its net anabolic effect on bone.

Bilateral Tibial Stress Fractures and Osteoporosis in a Young Patient.

Sports Health 2022 May-Jun;14(3):440-443. Epub 2021 Jul 23.

Division of Rheumatology, Physical Therapy and Rehabilitation Department, Firat University Hospital, Elazığ, Turkey.

Stress fractures result from microscopic bone injury due to repetitive submaximal stress and include fatigue and insufficiency fracture components. Fatigue fractures generally occur in runners and athletes and are caused by abnormal physical load on the bone. On the other hand, insufficiency fractures are generally seen in the elderly secondary to osteoporosis, typically involving the pelvis and surrounding bones. Read More

Clin Spine Surg 2021 10;34(8):286-290

Center for Spine Surgery, Neckar-Odenwald-Kliniken gGmbH Buchen, Buchen, Germany.

Nondisplaced and minimally displaced sacral insufficiency fractures are increasingly being recognized as a cause of immobilizing low back pain in the elderly. These insufficiency fractures are most accurately diagnosed by visualizing sacral bone marrow edema on magnetic resonance imaging, which is the radiologic imaging modality with the highest sensitivity for identifying these fractures. Successful treatment options range from nonsurgical (eg, bed rest, pain medication, mobilization, antiosteoporotic medication, low-intensity-pulsed ultrasound, etc. Read More

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
