	Achondrogenesis type II with normally developed extremities: a case report - Prenatal Diagnosis
	We present a case of achondrogenesis type II with normally developed extremities that was confirmed with postmortem ultrasonographic and radiographic examination. The length of the long bones may vary and the diagnosis of achondrogenesis should not be ruled out with normally developed extremities. Intrauterine sonographic examination of the vertebrae is very important and the absence of vertebral body ossification may be the unique finding of achondrogenesis type II. Axial ultrasonographic images and postmortem plain radiographs are useful to clarify the pathology...
	Pathophysiology and imaging in inflammatory and blastomatous synovial diseases - Skeletal Radiology
	These imaging modalities allow differentiation of characteristic pathologic features based on a profound knowledge of normal anatomy and pathophysiology...
	Short tau inversion recovery and three-point Dixon water-fat separation sequences in acute traumatic bone fractures at open 0.35 tesla MRI - Skeletal Radiology
	On the basis of qualitative and quantitative assessments, the three-point Dixon "sandwich" water-fat separation sequence was consistently superior to the STIR sequence in the delineation of traumatic fractures...
	Magnetic resonance imaging of Osgood-Schlatter disease: the course of the disease - Skeletal Radiology
	We clarified the progress of OSD with MRI. The process of OSD started from the apophyseal stage and a tear appeared in the secondary ossification center, widening to an opened shell-like shape. This damage progressed to an ossicle in some cases. In short, the ossicle was formed from an avulsed portion. It was very difficult to show the course of OSD with radiography. MR images were especially useful for revealing early and progressive lesions of OSD...
	Avascular necrosis of the epiphysis of the first metatarsal bone - Skeletal Radiology
	To our knowledge, this is the first radiological report of avascular necrosis of the epiphysis of the first metatarsal bone in the world literature, which prompted a review of the osteochondroses and their etiology...
	Clear cell chondrosarcoma mimicking chondroblastoma in a skeletally immature patient - Skeletal Radiology
	We report the case of a clear cell chondrosarcoma (CCCS) occurring in the femoral head of a 14-year-old skeletally immature boy. Radiographic examination revealed a well-defined, osteolytic lesion in the epiphysis of the femoral head...
	Calcific tendinitis of the gluteus medius tendon with bone marrow edema mimicking metastatic disease - Skeletal Radiology
	We present images from radiography, bone scanning, CT, and MR imaging. The unusual combination of findings in these studies should be considered conclusive for calcific tendinitis, and should not be confused with malignancy...

	Sonography of the Medial and Lateral Tendons and Ligaments of the Knee: The Use of Bony Landmarks as an Easy Method for Identification - American Journal of Roentgenology
	Bony landmarks can be identified in healthy adults on the medial and lateral aspects of the knee and may serve as reference points for identification of most medial and lateral tendons and ligaments...

May 28, 2002   Routine panoramic radiography of new adult patients in general dental practice: Relevance of diagnostic yield to treatment and identification of radiographic selection criteria - Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics Conclusion: Routine panoramic radiography of adult dental patients is not supported by the results of this study. The use of clinical indicators to select patients may help to improve diagnostic yield...   Traumatic injuries: imaging of pelvic fractures - European Radiology Radiological assessment must be included in multidisciplinary management and CT imaging stands for the most complete and least time-consuming device, allowing for investigation of both visceral and osseous lesions. In case of hemodynamic shock, external fracture stabilization and embolization of pelvic bleeding are preponderant. Tile/Association for Osteosynthesis classification is the most used presently. It allows good description of mechanisms and lesions and more adapted management...   Storage phosphor radiography of wrist fractures: a subjective comparison of image quality at varying exposure levels - European Radiology A choice of exposure settings according to the clinical situation (ALARA principle) is recommended to achieve possible dose reductions...   CT-guided percutaneous radiofrequency denervation of the sacroiliac joint - European Radiology Computed tomography-guided percutaneous radiofrequency denervation of the sacroiliac joint appears safe and effective. The procedure may be a useful therapeutic modality, especially in patients with chronic low back pain, who only temporarily respond to therapeutic blocks...   Gluteal mass in a bodybuilder: radiological depiction of a complication of anabolic steroid use - European Radiology We report an unusual case of a bodybuilder who developed a large painful inflammatory soft tissue mass in his gluteal area. Multi-modality imaging showed direct evidence revealing the underlying cause of the mass being depot steroid injections...   May 24, 2002   Radiography in acute ankle injuries: The Ottawa Ankle Rules versus local diagnostic decision rules - Annals of Emergency Medicine Conclusion: Because the identification of all relevant fractures is more important than a reduction in radiographs, the higher sensitivity of the Ottawa Ankle Rules makes these most suitable for implementation in The Netherlands...

May 23, 2002   Bilateral dysplasia epiphysealis hemimelica: report of two cases - Pediatric Radiology Dysplasia epiphysealis hemimelica is a rare congenital disorder characterised by unilateral bone overgrowth from large joints, mainly the ankle or knee. We present two cases with bilateral lesions; only two similar cases with bilateral involvement have been reported hitherto. The differential diagnosis is considered...   MRI assessment of the posterior acetabular wall fracture in traumatic dislocation of the hip in child - Pediatric Radiology We present two cases of pediatric traumatic hip dislocation associated with posterior wall fractures of the acetabulum. In both cases, obvious postreduction instability was noted without conclusive findings of etiology on plain X-rays or CT scans. Magnetic resonance imaging (MRI) disclosed an extensive posterior wall traumatic involvement in both cases and helped to decide in favor of open reduction of the hip and internal fixation of the posterior wall fragment...   A probable new type of osteopenic bone disease - Pediatric Radiology A probable new type of osteopenic bone disease in two sisters and one female cousin is described. In infancy, the radiological findings were osteopenia, coxa vara, periosteal cloaking, bowing of the long bones, and flaring of the metaphyses. During growth, spinal pathology developed with compression of the vertebral bodies and scoliosis in one girl and kyphosis in another. All three children had genu valgum and two developed severe S-shaped bowing of the tibiae. Growth was stunted. Inheritance of this disorder is probably recessive. Type I and III collagen biosynthesis was normal. This condition is probably a hitherto undescribed form of osteogenesis imperfecta type III or a new bone disease...   Missed cervical spine fracture-dislocations: The importance of clinical and radiographic assessment - Journal of Manipulative and Physiological Therapeutics Conclusion: Cervical spine fracture-dislocations are often missed during standard radiographic examinations in emergency department settings. Chiropractors are encouraged to perform a comprehensive evaluation of patients presenting with cervical trauma even if they have had prior x-ray films reported as normal. Standard x-ray films taken at emergency department facilities are not entirely reliable for detecting or revealing cervical spine fracture-dislocations. This case stresses the importance of careful clinical assessment and imaging procedures on patients who have encountered cervical spine trauma...   Self-reported exercise before age 40: Influence on quantitative skeletal ultrasound and fall risk in the elderly - Archives of Physical Medicine and Rehabilitation Conclusion: This study showed the important impact of current mobility and muscle strength status on bone structure, as measured by QUS at the calcaneus. In addition, a beneficial effect of former exercise on QUS and fall risk at advanced age could be documented in women. Both findings support life-long engagement in exercise, which might be particularly meaningful for women...   May 21, 2002   Utility of Tc-99m Human Polyclonal Immunoglobulin G Scintigraphy for Assessing the Efficacy of Yttrium-90 Silicate Therapy in Rheumatoid Knee Synovitis - Clinical Nuclear Medicine Conclusions: Quantitative Tc-99m HIG scintigraphy is a valuable method for assessing the efficacy of Y-90 silicate therapy in rheumatoid knee synovitis...   Lack of Effect of a Bisphosphonate (Pamidronate Disodium) Infusion on Subsequent Skeletal Uptake of Sm-153 EDTMP - Clinical Nuclear Medicine There was no difference in skeletal uptake of Sm-153 EDTMP before or at any time after pamidronate infusion. Pamidronate infusion did not interfere with skeletal uptake of Sm-153 EDTMP...   May 17, 2002   Skeletal maturation determined by cervical vertebrae development - European Journal of Orthodontics The results suggest that this new method to determine skeletal maturation is very reliable. A simple method based on morphological characteristics of the cervical vertebral bodies to evaluate the maturation stage has been designed. In the population investigated, this method is as accurate as the Hassel and Farman classification and superior to the Lamparski classification. The morphological vertebral parameter best able to estimate the maturation is the concavity of the lower border of the body...   May 15, 2002   Diagnosis of early Takayasu arteritis with sonography - Rheumatology Conclusion: Sonography of the carotid and subclavian arteries aids in the detection of early Takayasu arteritis. In young females with unclear symptoms and laboratory findings of generalized inflammation, the primary extracranial branches of the aortic arch should be investigated by sonography to detect early Takayasu arteritis...

May 14, 2002   Neuropathic osteoarthropathy - Applied Radiology A 75-year-old retired television repairman with diabetes, hypertension, and heart disease complained of foot pain and flat feet. He attributed his deformity and prior fractures to having "walked all over Europe and half the Pacific!" Physical examination of the right foot showed diminished sensation, pes planus, and a bony prominence of the medial midfoot with a 1-cm partial-thickness ulceration. The rest of the physical examination was essentially normal. Laboratory data revealed normal complete blood count, serum glucose of 173, spot microalbumin:creatinine ratio of 379, and glycosylated hemoglobins of 6.7 and 7.0...

May 13, 2002   Long term efficacy and safety of cyclosporin versus parenteral gold in early rheumatoid arthritis: a three year study of radiographic progression, renal function, and arterial hypertension - Annals of Rheumatic Diseases Conclusion: Three year changes in radiographic damage during cyclosporin and parenteral gold were similar in patients with early, active RA. Abnormal renal function and raised blood pressure were often seen in the cyclosporin treated patients...   May 10, 2002   Results of Operative Treatment of Fractures of the Posterior Wall of the Acetabulum - Journal of Bone and Joint Surgery Conclusion: The uncomplicated radiographic appearance and relatively simple operative approach for fractures of the posterior acetabular wall belie the risk of poor results. Prompt reduction of an associated hip dislocation is imperative. Fractures in elderly patients and those with extensive comminution are more likely to have a poor clinical result. However, a high likelihood of a long-term good-to-excellent result can be expected following anatomic reduction and internal fixation of these fractures...   Assessment of proximal finger joint inflammation in patients with rheumatoid arthritis, using a novel laser-based imaging technique - Arthritis & Rheumatism Conclusion: The new laser-based imaging technique allows the transillumination of PIP joints and gives information about the inflammatory status of the joint after processing through a neural network. Our data indicate that laser imaging may provide additional information in the early diagnosis of an inflammatory joint process and may prove particularly useful in assessing acute joint inflammation at followup ...   Knee pain reduces joint space width in conventional standing anteroposterior radiographs of osteoarthritic knees - Arthritis & Rheumatism Conclusion: JSW in weight-bearing extended-view radiographs of highly symptomatic OA knees can be altered significantly by changes in joint pain. In clinical trials and in epidemiologic studies of OA progression that use this radiographic technique, longitudinal variations in pain may confound changes in the apparent thickness of the articular cartilage ...   Quantitative computed tomography of the lumbar spine, not dual x-ray absorptiometry, is an independent predictor of prevalent vertebral fractures in postmenopausal women with osteopenia receiving long-term glucocorticoid and hormone-replacement therapy - Arthritis & Rheumatism Conclusion: In postmenopausal women with osteoporosis induced by long-term glucocorticoid treatment who are also receiving HRT, BMD of the lumbar spine as measured by QCT, but not DXA, is an independent predictor of vertebral fractures ...   Prospective Validation of the NEXUS Low-risk Criteria for Cervical Spine Radiography - Academic Emergency Medicine Conclusions: These data suggest that the NLC are less sensitive than previously believed, have fair interobserver agreement, and would have little impact on c-spine radiography ordering rates outside of the United States...   Soft tissue uptake on 99mTc methylene diphosphonate bone scan imaging: Pictorial review - Australasian Radiology We present a pictorial review sampling some of the many causes of extra-osseous 99mTc MDP accumulation...

May 09, 2002   A Lucky Fall or Radiological Diagnosis of an Endocrinopathy - International Pediatrics Conclusion: We report the incidental discovery of marked delay of bone ossification on a knee X-ray carried out on a neonate who sustained an accidental fall at home. The case emphasizes the need to be familiar with the suggestive radiological findings which may also be used to confirm the clinical suspicion of congenital hypothyroidism before the results of thyroid functions are available...   Congenital Dislocation of the Radial Head: Avoiding Post-traumatic Misdiagnosis - International Pediatrics Conclusion: We report the findings in 5 patients seen in our department with congenital dislocation of the radial head. Three cases corresponded to bilateral anterior dislocation, one case to bilateral posterior dislocation and one case to single posterior dislocation. Two of the anterior dislocation cases were first seen after traumatism with an initial misdiagnosis; evolution and X-ray of the contralateral elbow helped to find the correct diagnosis...   Evaluation of antegonial notch depth for growth prediction - American Journal of Orthodontics and Dentofacial Orthopedics We concluded that antegonial notch depth fails to provide sufficient indication of future facial growth to warrant its application as a growth predictor in a nonextreme population...   Computed tomography evaluation of temporomandibular joint alterations in Class II Division 1 subdivision patients: Condylar symmetry - American Journal of Orthodontics and Dentofacial Orthopedics Conclusion: The results of this study showed no statistically significant asymmetries between the condylar processes evaluated in this sample

May 02, 2002   Spinal injury Optimising the imaging options - European Journal of Radiology This chapter addresses these issues by reviewing the literature and provides a synopsis of the current thinking in the appropriate sections (adult, paediatric, symptomatic, asymptomatic, etc.) in the quest of finding out the correct answers on how best to exclude/confirm spinal trauma...   Vertebral injuries: detection and implications - European Journal of Radiology The imaging features described in this chapter apply to both radiography as well as to computed tomography (CT). Although helical CT is being used more commonly for the evaluation of suspected cervical injuries, radiography of the entire spine remains the standard...   Spinal trauma: therapy options and outcomes - European Journal of Radiology The purpose of this article is to provide an over view of the therapy options available in the treatment of these fractures. The article shall also look at some of the controversies surrounding the management of these fractures...   May 01, 2002   Unilateral adrenal hyperplasia causing primary aldosteronism: limitations of I-131 norcholesterol scanning - American Journal of Hypertension Conclusion: We report a patient with resistant hypertension and primary aldosteronism with a normal computed tomographic scan of the adrenal glands, a left-sided uptake on adrenal scintigraphy, and a right-sided lateralization of aldosterone after adrenal vein sampling. A repeat adrenal vein sampling confirmed the aldosterone lateralization to the right adrenal gland, which was then removed laparoscopically. The patient had a good clinical and biochemical response, and unilateral adrenal hyperplasia was discovered at histology. Excessive reliance on adrenal scintigraphy without adrenal vein sampling may lead to serious errors in patient management...   Dysplasia Epiphysealis Hemimelica Of Lateral Aspect Of The Distal Ulnar Epiphysis - Internet Journal of Radiology The purpose of this case report is to report a atypical case of a patient who had the lateral aspect of the distal ulnar epiphysis involved which has not been reported before, review the literature and discuss the management...
