Characterization of Insufficiency Fracture and Bone Metastasis After Radiotherapy in Patients With Cervical Cancer Detected by Bone Scan: Role of Magnetic Resonance Imaging.

Front Oncol 2019 28;9:183. Epub 2019 Mar 28.

Department of Radiology, Affiliated Cancer Hospital and Institute of Guangzhou Medical University, Guangzhou, China.

Insufficiency fracture (IF) can show increased uptake on a bone scan (BS). IFs are often misinterpreted as bone metastases if the characteristic "Honda sign" (H-sign) is invisible. The purpose of the present study was to evaluate the utility of magnetic resonance imaging (MRI) alone for the characterization of IF and bone metastasis after radiotherapy in patients with cervical cancer detected by BS.

The Association of Iliac and Sacral Insufficiency Fractures and Implications for Treatment: The Role of Bone Scans in Three Different Cases.

Cureus 2019 Jan 10;11(1):e3861. Epub 2019 Jan 10.

Neurological Surgery, University of Miami Hospital, Miami, USA.

Iliac wing fractures are under-diagnosed fractures often associated with sacral insufficiency fractures in osteoporotic patients. They are rarely seen alone. Insufficiency fractures of the iliac bone can often be missed on computerized tomography (CT) and magnetic resonance imaging (MRI) yet identified on radioisotope bone scans. Read More

Medial iliac stress fractures in athletes: report of two rare cases: review of literature and clinical recommendations.

Skeletal Radiol 2018 Nov 28. Epub 2018 Nov 28.

Department of Radiology, University of California San Diego, San Diego, CA, USA.

Stress fractures are a common diagnosis in sports medicine and can result in significant loss of function, athlete playing time, and potentially lead to chronic symptoms. However, unusual locations of stress fractures may present with vague symptoms and a relatively benign physical exam, leading to difficulty in arriving at the correct diagnosis. Pelvic stress fractures are less common than lower-extremity stress fractures in athletes, occurring in only 1-5% of all stress fractures and typically occur in pubic rami. Read More

Osteoid osteoma: multimodality imaging with focus on hybrid imaging.

Eur J Nucl Med Mol Imaging 2019 Apr 19;46(4):1019-1036. Epub 2018 Oct 19.

Department of Radiology and Nuclear Medicine, Cantonal Hospital Lucerne, Lucerne, Switzerland.

Osteoid osteoma is a painful, benign, osteoblastic lesion that occurs in younger patients and affects the extremities or the axial skeleton. While plain film findings may suggest the diagnosis, in complex anatomical regions such as the spine, pelvis, wrist and foot advanced imaging modalities are often required. A typical nidus surrounded by sclerosis or cortical thickening characterizes osteoid osteoma on plain radiography and CT. Read More

On the internal reaction forces, energy absorption, and fracture in the hip during simulated sideways fall impact.

PLoS One 2018 16;13(8):e0200952. Epub 2018 Aug 16.

Institute for Biomechanics, ETH Zürich, Zürich, Switzerland.

The majority of hip fractures have been reported to occur as a result of a fall with impact to the greater trochanter of the femur. Recently, we developed a novel cadaveric pendulum-based hip impact model and tested two cadaveric femur-pelvis constructs, embedded in a soft tissue surrogate. The outcome was a femoral neck fracture in a male specimen while a female specimen had no fracture. Read More

Lumbar spine MRI versus non-lumbar imaging modalities in the diagnosis of sacral insufficiency fracture: a retrospective observational study.

BMC Musculoskelet Disord 2018 Jul 25;19(1):257. Epub 2018 Jul 25.

Department of Radiology, Veterans Health Service Medical Center, 53, Jinhwangdo-ro 61-gil, Gangdong-gu, Seoul, 05368, Republic of Korea.

Background: Sacral insufficiency fractures (SIFs) are a common cause of lower back pain in the elderly. However, because clinical symptoms are frequently vague and nonspecific and can mimic lumbar spine pathologies, initial imaging in SIF patients is frequently targeted at the lumbar spine rather than the sacrum, resulting in delayed diagnosis. The purpose of this study is to show the proportions of modalities used in diagnosing SIF in practice and to compare the clinical and imaging features of SIF diagnosed by lumbar spine MRI (L-spine MRI) with those diagnosed by non-lumbar imaging modalities (bone scan, pelvic bone CT, pelvis MRI).

T9 versus T10 as the upper instrumented vertebra for correction of adult deformity-rationale and recommendations.

Spine J 2017 May 14;17(5):615-621. Epub 2016 Nov 14.

Department of Orthopedic Surgery, National University Health System, Singapore.

Background Context: Adult spinal deformity correction sometimes involves long posterior pedicle screw constructs extending from the lumbosacral spine to the thoracic vertebra. As fusion obliterates motion and places supraphysiological stress on adjacent spinal segments, it is crucial to ascertain the ideal upper instrumented vertebra (UIV) to minimize risk of proximal junctional failure (PJF). The T10 vertebra is often chosen to allow bridging of the thoracolumbar junction into the immobile thoracic vertebrae on the basis that it is the lowest immobile thoracic vertebra strut by the rib cage.

Nonspinal Fragility Fractures.

Semin Musculoskelet Radiol 2016 Sep 14;20(4):330-344. Epub 2016 Nov 14.

Department of Radiology, Auckland District Health Board, Auckland City Hospital, Greenlane Clinical Center, National Women's Hospital, Auckland, New Zealand.

This article focuses on nonspinal fragility or insufficiency fractures. Fragility fractures occur when normal levels of energy are applied to weakened bone, and they normally represent spontaneous fractures or traumatic fractures from minimal energy trauma that would not normally result in fracture in healthy people. This is the case in osteoporosis, where there is reduction of bone mass as well as loss of normal trabecular architecture leading to changes in structural characteristics that compromise biomechanics.

[Periprosthetic Acetabulum Fractures].

Z Orthop Unfall 2016 Dec 6;154(6):560-570. Epub 2016 Oct 6.

Klinik für Unfall- und Wiederherstellungschirurgie, BG-Unfallklinik Tübingen.

In contrast to periprosthetic fractures of the femur, periprosthetic fractures of the acetabulum are rare complications - both primary fractures and fractures in revision surgery. This topic is largely under-reported in the literature; there are a few case reports and no long term results. Due to an increase in life expectancy, the level of patients' activity and the number of primary joint replacements, one has to expect a rise in periprosthetic complications in general and periprosthetic acetabular fractures in particular.

Pelvic insufficiency fractures in women following radiation treatment: a case series.

Ann Palliat Med 2016 Jul 27;5(3):233-7. Epub 2016 May 27.

Department of Radiation Oncology, Odette Cancer Centre, Sunnybrook Health Sciences Centre, University of Toronto, Toronto, Ontario, ON, Canada.

Insufficiency fractures are stress fractures that occur from normal weight-bearing on weakened bone. Radiation treatment to malignancies in the prostate, rectum, anus, or cervix may increase the risk of insufficiency fractures in the pelvic region by damaging osteoblasts that are essential to bone formation. In elderly women with cancer, this risk is greater due to their susceptibility to developing osteoporosis. Read More

Cement Augmentation in Sacroiliac Screw Fixation Offers Modest Biomechanical Advantages in a Cadaver Model.

Clin Orthop Relat Res 2016 Nov 22;474(11):2522-2530. Epub 2016 Jun 22.

Division of Orthopaedic Trauma, Department of Orthopaedics, University of British Columbia, 3114-910 West 10th Avenue, Vancouver, BC, V5Z 1M9, Canada.

Background: Sacroiliac screw fixation in elderly patients with pelvic fractures is prone to failure owing to impaired bone quality. Cement augmentation has been proposed as a possible solution, because in other anatomic areas this has been shown to reduce screw loosening. However, to our knowledge, this has not been evaluated for sacroiliac screws. Read More

Department of Radiology, New York University, Langone Medical Center, New York, NY, 10016, USA.

Stress fracture, in its most inclusive description, includes both fatigue and insufficiency fracture. Fatigue fractures, sometimes equated with the term "stress fractures," are most common in runners and other athletes and typically occur in the lower extremities. These fractures are the result of abnormal, cyclical loading on normal bone leading to local cortical resorption and fracture. Read More
