July 26, 2002     Recommendations for GPs regarding imaging with respect to low back pain - New Zealand Family Physician Conclusion: Where there is consensus on the literature, GPs should adhere to recommendations. Lack of consensus justifies GP clinical flexibility. A greater awareness by doctors and patients of radiation levels involved may diminish ordering lumbar x-rays when serious pathology is unlikely...   Radiographic evaluation of the knee joint after meniscal allograft transplantation. An experimental study in rabbits - Knee Surgery, Sports Traumatology, Arthroscopy Conclusion: Our findings suggest that meniscal allograft transplantation does not prevent degenerative changes in the rabbit knee on a long term...   Laser Stimulation on Bone Defect Healing: An In Vitro Study - Lasers in Medical Science Conclusion: These in vitro results suggest that Ga-Al-As LPL treatment may play a positive role in bone defect healing...   July 25, 2002   Distinct focal lesions of the femoral head: imaging features suggesting an atypical and minimal form of bone necrosis - Skeletal Radiology Conclusion. A distinct, focal lesion of the femoral head is believed to represent an atypical form of bone necrosis. Its restriction to a small portion of the femoral head may relate to localized vascular anatomy. Recognition of the quite characteristic imaging findings can prevent misdiagnosis and may have implications for the prediction of the natural course of the disease...   Ollier's disease in association with adjacent fibromatosis - Skeletal Radiology We report a case of Ollier's disease in association with soft tissue fibromatosis adjacent to the involved upper arm...   Osteosarcoma arising in a femur with melorheostosis and osteopathia striata - Skeletal Radiology We report a 44-year-old man with both melorheostosis and osteopathia striata who presented with pain secondary to superimposed osteosarcoma.

The new system allows greater precision in assessing fracture reduction and follow-up. Its principal application is in studies that utilise the wrist as a model for fracture healing...   Lumbar radiculopathy caused by a tunneling transvertebral Schmorl's node - Skeletal Radiology We report a rare case of lumbar spinal radiculopathy caused by a tunneling Schmorl's node originating from the superior endplate of the L3 vertebra of a 75-year-old patient and penetrating the spinal canal through the posterior wall of this vertebra. This case highlights recent reports emphasizing the clinical pain syndromes possibly associated with Schmorl's nodes...   Microscopic correlation of radiographically disparate appearing well differentiated osteosarcoma - Skeletal Radiology We believe this microscopic interpretation explains the disparate radiographic appearance as all belonging to well differentiated osteosarcoma with varying amounts of fibrous dysplasia-like tissue rather than the development of well differentiated osteosarcoma in fibrous dysplasia...

July 22, 2002   Effect of articular cartilage proteoglycan depletion on high frequency ultrasound backscatter - Osteoarthritis and Cartilage Conclusion: Current results indicate that PG depletion has no significant effect on high frequency ultrasound backscattered from rat patellar cartilage. Ultrasound may provide information about variations of PG content via speed of sound measurement. ...   July 19, 2002   Editorial: Magnetic resonance imaging of the knee - British Medical Journal Magnetic resonance imaging has had an enormous impact on musculoskeletal imaging and in this area the knee is the most frequently imaged joint. The steadily increasing availability of magnetic resonance imaging is moving the investigation from the realms of the last resort of the hospital specialist to part of the diagnostic evaluation by the general practitioner ...   July 17, 2002   Reappraisal of use of X-rays in childhood ankle and midfoot injuries - Emergency Radiology Conclusions: The Ottawa ankle rules are very sensitive and can be applied in children, resulting in a reduction in the use of X-rays studies...   Reliability of vacuum phenomenon in the sacroiliac joint as a sign of traumatic injury - Emergency Radiology Conclusion: Gas in the sacroiliac joint is not a reliable indicator of sacroiliac joint injury...   A reassessment of bone scintigraphy and commonly tested pretreatment biochemical parameters in newly diagnosed osteosarcoma - Journal of Cancer Research & Clinical Oncology Conclusion: The strongest predictor of survival in osteosarcoma is the presence or absence of metastasis. Some biochemical parameters have prognostic value, but they cannot be used for the unequivocal identification of subgroups. Additional scintigraphic parameters are irrelevant for prognostic stratification...   July 15, 2002   Folate-targeted imaging of activated macrophages in rats with adjuvant-induced arthritis - Arthritis & Rheumatism Conclusion: Although EC20 is currently undergoing clinical evaluation for use in the imaging of ovarian carcinomas, the present results suggest that it may also be useful for assaying the participation of activated macrophages in inflammatory processes such as rheumatoid arthritis ...

July 12, 2002   Juvenile dermatomyositis with a fracture of soft-tissue calcinosis in the left biceps muscle - Applied Radiology 10-year-old girl with a 7-year history of a chronic disease presented with pain localized to the left upper extremity...   July 11, 2002   MR Imaging of the Postoperative Knee: A Pictorial Essay - Radiographics Finally, MR imaging has been shown to be accurate in the evaluation of cartilage repair tissue. Knowledge of the normal MR imaging appearance of the knee after the more common repair procedures will allow radiologists to recognize complications associated with such procedure...   Anatomy and MR Imaging Appearances of Synovial Plicae of the Knee - Radiographics Synovial plicae are normal anatomic structures of the knee that sometimes become symptomatic. Magnetic resonance (MR) imaging and MR arthrography are useful tools in the evaluation of synovial plicae and allow differentiation of these entities from other causes of knee pain...   July 10, 2002   The Radiographic Evaluation of Keeled and Pegged Glenoid Component Insertion - Journal of Bone and Joint Surgery Conclusions: Perfectly cementing and seating a glenoid replacement is a difficult task. Radiolucencies and incomplete component seating occur more frequently in association with keeled components compared with pegged components. Surgeon experience may be an important variable in the achievement of a good technical outcome...   Radiological and manometric diagnosis of cricopharyngeal dysphagia in a Japanese encephalitis survivor - European Journal of Neurology Case report: We report a 55-year-old male who survived from JE and was left with sequela of parkinsonism and severe swallowing disorder...

July 09, 2002   Imaging in Scoliosis: What, Why and How? - Clinical Radiology Scoliosis may be a spinal manifestation of underlying disease and although most cases of scoliosis are idiopathic, imaging plays a very important role in determining the underlying aetiology and in monitoring the changes of the deformity that take place with growth. As a clinical problem scoliosis may present directly to the radiology department through a primary healthcare referral, or it may be referred from the paediatric, orthopaedic, spinal and neurosurgical hospital services. Growth affects all types of scoliosis irrespective of cause...   Segmental Lumbar Spine Instability at Flexion-Extension Radiography can be Predicted by Conventional Radiography - Clinical Radiology Conclusion: Sliding instability is strongly associated with various plain radiographic findings. In mechanical back pain, functional flexion-extension radiographs should be limited to situations when symptoms are not explained by findings of plain radiographs and/or when they are likely to alter therapy...   July 08, 2002   Natural History and Distribution of Bone and Bone Marrow Infarction in Sickle Hemoglobinopathies - The Journal of Nuclear Medicine Conclusion: Knowledge of the distribution and natural history of sites of bone and bone marrow infarction is of considerable clinical and diagnostic import in the ongoing evaluation and treatment of sickle hemoglobinopathies...   July 02, 2002   Discovertebral lesion in ankylosing spondylitis: differential diagnosis with discitis by magnetic resonance imaging - Modern Rheumatology The details of these three cases are reviewed, and the importance of differentiating between Andersson lesions and bacterial discitis is discussed.
