Radiological scoring methods in ankylosing spondylitis. Reliability and change over 1 and 2 years.

OBJECTIVE: To compare reliability and change over time of radiological scoring methods in ankylosing spondylitis (AS). METHODS: Two trained observers scored 217 sets of radiographs from baseline and from one and 2 years' followup. Sacroiliac (SI) joints were grade 0-4 by the New York method and Stoke Ankylosing Spondylitis Spine Score (SASSS). Hips and cervical and lumbar spine were graded 0-4 by Bath Ankylosing Spondylitis Radiology Index (BASRI). BASRI spinal scores and New York SI are combined into BASRI-spine (score 2-12) and with the addition of BASRI-hips into BASRI-total (2-16). Cervical and lumbar spine were also scored in detail (SASSS, 0-36 each) and were combined into SASSS-total or "modified" SASSS (both range 0-72). To assess change a smallest detectable difference (SDD) was estimated for data on a quasi-interval scale. RESULTS: The SI scoring methods showed intra and interobserver kappa between 0.36 and 0.70. The BASRI-hip reached kappa between 0.59 and 0.84. Combined SASSS scores were most reliable, with intra and interobserver intraclass correlation coefficients (ICC) between 0.90 and 0.96. The ICC of the combined BASRI scores were also very good, ranging from 0.85 to 0.95. For SI New York, SI SASSS, and BASRI-hip, 0.3-1.2% of patients deteriorated 1 grade; 7.5% deteriorated 1 grade (6.3% of maximum score) in BASRI-spine and BASRI-total, and observers agreed in up to 48% of the cases that no change occurred. The SDD was lowest (7.5; 10% of maximum score) for "modified" SASSS. Only 0.8% of patients deteriorated more than the SDD and observers agreed in up to 92% of the cases that no change occurred. CONCLUSION: Radiological scoring methods for AS are moderately to excellently reliable. Under the selected scoring conditions (concealed time order, average of 2 observers, SDD based on interobserver data, unselected patient population) there was too little change over 2 years to be detected reliably by the scoring methods.

Computed tomography of rheumatologic disorders. Part II.

The advent of computed tomographic (CT) scanning has initiated a revolutionary approach to the evaluation of articular disease. CT affords the opportunity to noninvasively evaluate both osseous and soft tissue structures during a single diagnostic examination. An optimal CT study demands proper technique, including a localization image, appropriate slice thickness and spacing, and window/level manipulation. The examination must be tailored to the specific indication for the study, which may include degenerative processes, inflammatory disease, or unexplained clinical symptomatology.

[Unusual indications for scanning in osteoarticular pathology].

The authors take stock of current applications of the scanner in osteoarticular pathology. At first (1978-1983 approximately), only the vertebral column could be studied by this technique. Now, almost all the osteoarticular system is susceptible to study. Established examples are: study of the sacrum, of the traumatized acetabulum, of the femoropatellar apparatus, and measurement of torsion in the lower limbs. New applications are: study of the back of the foot, of the patellar cartilage, of the glenoid cavity, of the bones and soft parts of the hand, three-dimensional reconstructions, scanning radiology. The authors index and analyse these new techniques.
