August 28, 2002   Pseudoarthrosis and ankylosis of the vertebral spine without sacroiliitis associated with Takayasu's arteritis: review of the association - Skeletal Radiology Pseudoarthrosis and ankylosis of the vertebral spine associated with Takayasu's arteritis is extremely rare. We present a patient with the entity who was HLA-B27 negative and had normal sacroiliac joints. The association between Takayasu's arteritis and ankylosing spondylitis appears real but seemingly rare...   August 27, 2002   Lumbosacral interspinous ligament rupture associated with acute intrinsic spinal muscle degeneration - European Radiology Conclusion: Because this study was an observational one, based solely upon medical imaging, future research must focus upon the correlation of the relevance of these findings with an age-matched asymptomatic control group and longitudinal clinicoradiologic therapeutic trials...   Radiographic Assessment of Bone Formation in Tibia During Distraction Osteogenesis - Journal of Pediatric Orthopaedics Conclusion: No feature was associated with a 100% chance of a satisfactory outcome, but certain appearances in the regenerate were associated with a better BHI than others...   August 26, 2002   Orientational diffusion reflects fiber structure within a voxel - Magnetic Resonance in Medicine Several new MR techniques have been introduced to infer direction through diffusion in multiple nerve fiber bundles within a voxel. To date, however, there has been no physical model reported to evaluate these methodologies and their ability to determine fiber orientation. Orientational diffusion measurements are shown to reflect fiber geometry and theoretical predictions to within 10%. Simulations of fiber crossings within a voxel suggest fiber orientation does not correspond to the direction of the largest measured diffusion coefficient, but theoretical knowledge of signal decay curves can predict the shape of these diffusion coefficient contours for given fiber orientation probabilities...   Orientational dependence of T2 relaxation in articular cartilage: A microscopic MRI (MRI) study - Magnetic Resonance in Medicine We show that even for the long T2 components, which arise in multiple-compartment studies of collagen-water systems, there appears to be two subpopulations. Each has the same peak value of T2, but the angular dependence of one is shifted in phase by 90° relative to the other by virtue of the fact that each is associated with groups of mutually perpendicular fibrils...   August 22, 2002   Magnetic Resonance Imaging Diagnosis of a Deep Soft Tissue Leiomyoma under the Rectus Muscle - Gynecologic and Obstetric Investigation Conclusion: Leiomyomas of the deep soft tissue are extremely rare. We report a case of a deep soft tissue leiomyoma that was difficult to differentiate from a uterine leiomyoma. A 48-year-old woman was diagnosed with a uterine leiomyoma, but surgical and pathological findings revealed a deep soft tissue leiomyoma and normal uterus...   Cervical spine in patients with diastrophic dysplasia - radiographic findings in 122 patients - Pediatric Radiology Conclusion: The most common alignment in the cervical spine is lordosis in adulthood. The vertebral bodies are flattened and the spinal canal is narrowed. Vertebral body hypoplasia and displacement usually resolve spontaneously during growth. Degenerative changes in the cervical spine are common, but vertebral anomalies are rare. Prevalence of SBO is high...   Gracile bone dysplasias - Pediatric Radiology Conclusion: Exact diagnosis of a gracile bone dysplasia is important for genetic counselling and medico-legal reasons...   Prospective Screening for Blunt Cerebrovascular Injuries: Analysis of Diagnostic Modalities and Outcomes - Annals of Surgery Conclusion: Aggressive screening of patients with blunt head and neck trauma identified an incidence of BCVI in 1.03% of blunt admissions. Early identification, which led to early treatment, significantly reduced stroke rates in patients with VAI, but provided no outcome improvement with CAI. More encompassing screening may be required to improve outcomes for patients with CAI. However, less-invasive diagnostic techniques (CTA and MRA) are inadequate for screening. Technological advances are necessary before abandonment of conventional angiography, which remains the standard for diagnosis ...   Rib fractures after chest physiotherapy for bronchiolitis or pneumonia in infants - Pediatric Radiology Conclusion: CPT should be considered a potential, but very rare cause of rib fractures in infants. It can be of clinical relevance when rib fractures are the only feature suggestive of child abuse...

August 21, 2002   Computer-assisted Cobb measurement of scoliosis - European Spine Journal The technique developed allows an observer to measure the spinal curvature with a high resolution and accuracy. One important advantage of the technique is that the assessor does not need to be skilled or experienced in measurement of a spinal curvature...   MRI changes of cervical spine in asymptomatic and symptomatic young adults - European Spine Journal These findings indicate that pathophysiological changes of cervical spine verified on MRI seem to explain only part of the occurrence of neck and shoulder pain in young adults...   August 15, 2002   Interdisciplinary cooperation to improve function and long-term survival in patients with high-grade osteosarcoma of the extremities - Der Chirurg Conclusion: In patients with osteosarcoma of the extremities, limb salvage is possible in a high percentage of cases with a low risk of local recurrence by an effective interdisciplinary cooperation between diagnostic radiologists, oncologists, and orthopedic surgeons. The midterm survival could be improved by the multimodal therapy from about 20% up to about 80%. Metastasectomy gives patients with a limited number of pulmonary metastases a realistic chance to survive...   August 14, 2002   Electrodiagnosis of ulnar neuropathy at the wrist - Neurology In UNW, an additional palmar stimulation site improves electrodiagnostic yield, and demonstrates that CB is an important cause of muscle weakness...   August 06, 2002   Assessment of Articular Fragment Displacement in Acetabular Fractures: A Comparison of Computerized Tomography and Plain Radiographs - Journal of Orthopaedic Trauma Conclusions: 1) Plain radiographs showed poor sensitivity for the detection of step and gap deformities in patients with acetabular fractures and in osteotomized canine specimens, relative to CT scans; 2) differences between CT and plain radiographs in both specimen types were greatest with the most clinically relevant deformity-i.e., step; and 3) CT scans are essential and should continue to be used in conjunction with plain radiographs in the preoperative evaluation of displaced acetabular fractures and perhaps should be considered in the postoperative assessment of fracture reduction...

August 05, 2002   Lumbar Bone Mineral Density at Final Height and Prevalence of Fractures in Treated Children with GH Deficiency - Journal of Clinical Endocrinology and Metabolism The results show that treated patients with GHD have normal mean values of lumbar BMDvolume at final height, but some patients have reduced lumbar BMD (Z score <1) with an increased susceptibility to fractures...   August 02, 2002   Meniscal and articular cartilage changes in knee osteoarthritis: a cross-sectional double-contrast macroradiographic study - Rheumatology Conclusion: Although the cross-sectional nature of this study precluded definite aetiological inferences, this study showed that degenerative changes in the meniscal and articular cartilages were not totally variable. Because of its larger articular surface, changes in the medial femoral cartilage were less marked than at the meniscal and tibial cartilages in the osteoarthritic compartment...   A Training Program in Portable Fluoroscopy for the Detection of Glass in Soft Tissues - Academic Emergency Medicine Emergency medicine residents previously inexperienced in fluoroscopy may, through a brief training intervention, acquire the skill to accurately detect small pieces of glass in a chicken leg model, and maintain proficiency one week later. Further studies of emergency department fluoroscopy in GFB management in humans are warranted...   How Reliable Is Clinical Examination for Detecting Pelvic Fractures? - American Health Consultants - Hot Topics in Healthcare The purpose of this study was to prospectively evaluate the sensitivity of clinical examination as a screening modality for pelvic fractures in awake, alert blunt trauma patients... The results of this trial are consistent with four prior studies demonstrating that a good physical examination can exclude pelvic injury in the majority of alert patients. In this study, the sensitivity of the clinical examination was actually better than radiography...   Use of bone biochemical markers with dual-energy x-ray absorptiometry for early determination of bone loss in persons with spinal cord injury - Metabolism-Clinical and Experimental In conclusion, it was not possible to detect any variation in BMD from the DXA technique at this early stage of demineralization, but the sensitivity and early response of the biochemical markers strongly suggested their usefulness for the early identification of persons with SCI at risk of severe osteoporosis...   August 01, 2002   Joint Space Narrowing and Relationship with Symptoms and Signs in Adults Consulting for Hip Pain in Primary Care - Journal of Rheumatology Conclusion: In primary care patients with hip pain, clinical symptoms and signs can to a moderate extent predict radiological OA and to a large extent more severe radiological OA...
