May 29, 2003     Musculoskeletal images: Knee-joint tuberculosis - Canadian Journal of Surgery A 76-year-old woman was seen because of increasing pain in and deformity of her right knee...     Distinguishing transient osteoporosis of the hip from avascular necrosis - Canadian Journal of Surgery Conclusion: Despite recent publications, the prevalence of TOH among young men is still overlooked and the distinctive MRI appearance still misinterpreted. Symptoms may be severe but resolve over time with reduced weight bearing. The absence of focal changes on MRI is highly suggestive of a transient lesion. A greater level of awareness of this condition is needed to differentiate TOH from AVN, avoiding unnecessary surgery and ensuring appropriate treatment...   Device-specific weighted T-score for two quantitative ultrasounds: operational propositions for the management of osteoporosis for 65 years and older women in Switzerland - Osteoporosis International Conclusion: The application of this approach will help to minimize the inappropriate use of QUS from which the whole field currently suffers...   The effect of age, weight, and lifestyle factors on calcaneal quantitative ultrasound: the ESOPO study - Osteoporosis International In conclusion, QUS bone measurements discriminate postmenopausal women according to past use of hormone replacement therapy.

May 23, 2003   Osseous Change Adjacent to Soft-Tissue Hemangiomas of the Extremities: Correlation with Lesion Size and Proximity to Bone - American Journal of Roentgenology Soft-tissue hemangiomas of the extremities frequently result in adjacent osseous change that can be categorized as either periosteal, cortical, or medullary. Only medullary changes correspond with hemangioma size, whereas all three categories of change correlate with the proximity of the hemangioma to the adjacent bone. The presence of osseous change does not correlate with patient symptomatology... May 22, 2003   Pseudomass of the sternal manubrium in osteogenesis imperfecta - Skeletal Radiology Computed tomography examination revealed a high-density mass-like lesion of the manubrium sterni. Ultrasonography and a lateral roentgenogram of the chest verified that this was a pseudomass caused by a bowed sternal manubrium...   Multimodality imaging features of primary xanthoma of the calcaneus - Skeletal Radiology There was no evidence of pre-existing lesions. Total excision of the tumor was curative...   Value of MRI in the diagnosis of non-clival, non-sacral chordoma - Skeletal Radiology Conclusions: Although the SI on MR imaging is not specific, chordoma should be considered when a destructive lesion of a vertebral body is associated with a soft tissue mass with a collar button or mushroom appearance and dumbbell morphology, spanning several vertebral segments and sparing the disk(s)...   Postgraduate musculoskeletal fellowship training in the United States: current trends and future direction - Skeletal Radiology Conclusions: The majority of musculoskeletal training programs prepared trainees for private or academic practice. There are inconsistencies that could be improved to better prepare trainees for careers in musculoskeletal imaging...   Imaging features of traumatic dislocation of the lumbosacral joint associated with disc herniation - Skeletal Radiology Bilateral facet dislocation of the lumbosacral joint is an uncommon injury.

In patients receiving X-ray of the hand for diagnostic purposes, the new technology is feasible, because for the patient no additional radiation exposure is necessary in order to estimate BMD...   Assessment of prevalent and incident vertebral fractures in osteoporosis research - Osteoporosis International Conclusion: We firmly believe that the experience from several studies has shown that there is a major role for radiologists and clinicians alike to carefully assess and diagnose vertebral fractures using standardized grading schemes such as the one proposed in this review. In the context of epidemiologic studies and clinical drug trials, quantitative morphometry may be used; however, the studies would be flawed if quantitative morphometry were to be performed in isolation without additional adjudication by a trained and highly experienced radiologist or clinician...   Exposure to Diagnostic Ionizing Radiation in Sports Medicine: Assessing and Monitoring the Risk - Clinical Journal of Sport Medicine Conclusions: Certain investigations have a greater effective dose and risk estimate than others. Elite athletes may potentially undergo numerous investigations in their career. An athlete radiation record may be useful to better manage this exposure ...   Hip Joint Pathology: Clinical Presentation and Correlation Between Magnetic Resonance Arthrography, Ultrasound, and Arthroscopic Findings in 25 Consecutive Cases - Clinical Journal of Sport Medicine Conclusions: Hip pathology, particularly labral pathology, may be more common than has been previously recognized. In those patients with chronic groin and low back pain, a high index of suspicion should be maintained. Clinical signs of a painful, restricted hip quadrant and a positive FABER test result should suggest magnetic resonance arthrography in the first instance, but a negative magnetic resonance image should not preclude hip arthroscopy if there is high clinical suspicion of hip joint pathology ...   Agreement Between Magnetic Resonance Imaging and Arthroscopic Evaluation of the Shoulder Joint in Primary Anterior Dislocation of the Shoulder - Clinical Journal of Sport Medicine Conclusions: Magnetic resonance imaging can be considered a valuable tool for the detection of Hill-Sachs and Bankart lesions associated with primary traumatic anterior dislocations of the shoulder. Its ability to detect other pathologic lesions, however, is limited ...

Besides contributing to diagnosis, MRI provides a precise assessment necessary for correcting the prosthesis-stump interface in a way that reduces mechanical stress and subsequently cures bursitis... May 07, 2003   ARRS: Computed Tomography-Guided Interventional Procedures Promising In Treating Back Pain - Musculoskeletal and Connective Tissue Disorders, Doctor's Guide news Computed tomography-guided interventional procedures offer highly accurate and conservative therapies for patients with back pain, decreasing the need for pain medications and delaying the need for surgical treatment, according to a recent study...   Achilles Tendons: Clinical Relevance of Neovascularization Diagnosed with Power Doppler US - Radiology Conclusion: Although neovascularization is a specific sign for pain, it does not indicate an unfavorable outcome. Conversely, tendon inhomogeneity seems to be associated with an unfavorable outcome...

	Camptodactyly, Arthropathy, Coxa Vara, and Pericarditis Syndrome Among Egyptians - Journal of Rheumatology
	Conclusion: Our cases represent a familial syndrome of noninflammatory arthropathies associated with camptodactyly and coxa vara. The complete picture of the syndrome may be related to disease duration, and MRI is a useful tool in diagnosis. Physicians should be aware of the syndrome, to avoid misdiagnosis with other pediatric connective tissue diseases...
	Ultrasonography Is Superior to Clinical Examination in the Detection and Localization of Knee Joint Effusion in Rheumatoid Arthritis - Journal of Rheumatology
	Conclusion: US is more sensitive than CE in the detection of suprapatellar bursitis, knee effusion, and Baker's cyst in RA. CE underestimates knee inflammation in RA. This has implications for the use of CE as a component of standardized disease activity scores and in guiding knee joint aspiration...
	The Incidence of False Negative Initial Cervical Spine Radiographs for Patients Admitted to a Level-I Trauma Center - Academic Emergency Medicine
	Conclusion: Plain radiography fails to reveal C-spine fracture or dislocation in approximately 15% of patients with proven injury. C-spine injury cannot be excluded by plain film in a substantial number of patients. Physicians should consider ordering C-spine CTs on patients unable to be cleared by other means...
