| Association of baseline levels of urinary glucosyl-galactosyl-pyridinoline and type II collagen C-telopeptide with progression of joint destruction in patients with early rheumatoid arthritis - Arthritis & Rheumatism | |
|
|
Conclusion: High baseline levels of Glc-Gal-PYD, CTX-II, and MMP-3 are associated with increased risk of progression of joint destruction over 1 year in early RA. The association between baseline levels of urinary Glc-Gal-PYD and progression of joint erosion was independent of the severity of radiologic damage and inflammation at baseline. Combining the measurements of these molecular markers with radiologic assessment of joint damage may be useful for identifying patients with RA who are at high risk of rapid progression and for whom early aggressive treatment would be beneficial ... |
| Field test of the reproducibility of the semiflexed metatarsophalangeal view in repeated radiographic examinations of subjects with osteoarthritis of the knee - Arthritis & Rheumatism | |
|
|
Conclusion: The semiflexed MTP protocol affords highly reproducible radioanatomic positioning of the knee, although misalignment of the medial tibial plateau and the x-ray beam occurs in >70% of cases. Precision of measurement of JSW in the semiflexed MTP view approaches that associated with fluoroscopically assisted positioning protocols. However, the consequences of poor, albeit reproducible, alignment of the knee in serial semiflexed MTP radiographs in longitudinal studies of OA progression are currently unknown ... |
| The relationship of bone density and fracture to incident and progressive radiographic osteoarthritis of the knee: The Chingford study - Arthritis & Rheumatism | |
|
|
Conclusion: These results confirm that for women who develop incident knee OA, defined by osteophytes, BMD is higher and of a magnitude similar to that shown in cross-sectional studies. Low BMD at the hip appears weakly related to progression. Women with previous fractures have less chance of developing OA, independent of BMD status. Although the mechanism for this action is unclear, these results suggest a possible common role of bone turnover and repair in the early manifestations of OA ... |

| January 10, 2002 | |
| Implementation of the Ottawa ankle rule in a university sports medicine center - Medicine and Science in Sports and Exercise | |
|
|
Conclusion: The OAR reduced radiography in acute ankle/midfoot injury and saved money in relatively younger patients in the outpatient sports urgent care setting without missing any clinically significant fractures. The specificity of the Buffalo malleolar rule in the present implementation study, however, was not a significant improvement over the OAR malleolar rule. Widespread application of the OAR could save substantial resources without compromising quality of care... |

| The Role of Plain Films and Computed Tomography in the Evaluation of Scapular Neck Fractures - Journal of Orthopaedic Trauma | |
|
|
Conclusion: Scapular neck fracture displacement, angulation, and anatomic classification showed moderate interobserver reliability by plain films but were not enhanced by computed tomography. Computed tomography confused, rather than clarified, the assessment of these characteristics. Computed tomography may be useful to identify associated injuries to the superior shoulder suspensory complex, which can be missed by plain films alone. Routine computed tomography in patients with scapular neck fractures cannot be recommended based on this study. Computed tomography of scapular neck fractures may be useful in selected cases in which intraarticular extension is noted on plain films... |
| Teleradiology in Orthopaedic Surgery: Impact on Clinical Decision Making for Acute Fracture Management - Journal of Orthopaedic Trauma | |

| Bone densitometry in the management of Colles' fractures: which site to measure? - British Journal of Radiology | |
|
|
A peripheral bone
mineral densitometry strategy using forearm BMD alone will miss
many individuals with osteoporosis. Therefore where forearm, and
probably any peripheral scanning method, only is used for
patient assessment there should be close liaison with an axial
BMD centre with agreed joint protocols, as some patients should
be advised to have an additional axial BMD measurement following
their peripheral BMD measurement...
|
| Cervical spine radiography in alert asymptomatic blunt trauma patients - Emergency Medicine Journal | |
|
|

Altogether 232 papers were found using the reported search, of which six presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are shown in table 2. A clinical bottom line is stated... |
| Isolated Anterior Arch Fracture of the Atlas - Spine | |
|
|
On plain radiographs, fractures of the atlas and anterior aspect in particular may remain occult. Accurate diagnosis of atlas fractures depends on further radiologic investigations including computed tomography and magnetic resonance imaging. Experience in treating atlas fractures is insufficient because of a paucity of literature. Immobilization with a firm cervical collar is the treatment of choice in stable atlas fracture... |
| Stress Reactions of the Lumbar Pars Interarticularis - Spine | |

| Comparison of Long-Term Functional and Radiologic Outcomes After Harrington Instrumentation and Spondylodesis in Adolescent Idiopathic Scoliosis - Spine | |
|
|
. In patients with adolescent idiopathic scoliosis who undergo surgery with Harrington instrumentation, the overall long-term clinical outcome does not correlate with the radiologic outcome. However, a significant inverse correlation was found between the magnitude of the primary thoracic curve at follow-up assessment and the scores for questions on cosmetic matters in the Scoliosis Research Society questionnaire. Spine mobility is diminished as a result of spondylodesis, but the patients perform, on the average, as well as the normal population in nondynamometric trunk strength measurements... |
| Young Investigator Award 2001 Winner: Risk Factors for Lumbar Disc Degeneration - Spine | |
|
|
