A standardized method to assess structural osteoarthritis (OA) burden thorough the body lacks from literature. Such a method can be valuable in developing personalized treatments for OA. We developed a reliable scoring system to evaluate OA in large joints and the spine—the OsteoArthritis Computed Tomography (OACT) score, using a convenience sample of 197 whole-body low-dose non-contrast CTs. An atlas, containing example images as reference points for training and scoring, are presented. Each joint was graded between 0–3. The total OA burden was calculated by summing scores of individual joints. Intra- and inter-observer reliability was tested 25 randomly selected scans (N = 600 joints). Intra-observer reliability and inter-observer reliability between three observers was assessed using intraclass correlation coefficient (ICC) and square-weighted kappa statistics. The square-weighted kappa for intra-observer reliability for OACT-score at joint-level ranged from 0.79 to 0.95; the ICC for the total OA grade was 0.97 (95%-CI, 0.94 to 0.99). Square-weighted kappa for interobserver reliability ranged from 0.48 to 0.95; the ICC for the total OA grade was 0.95 (95%-CI, 0.90 to 0.98). The OACT score, a new reproducible CT-based grading system reflecting OA burden in large joints and the spine, has a satisfactory reproducibility. The atlas can be used for research purposes, training, educational purposes and systemic grading of OA on CT-scans.

“…This can be interpreted as an indication that a limited part of the cartilage layer is subjected to osteoarthrosis but other parts of the joint surface have normal cartilage thickness. This has been described by Collins [2] and was found in a previous investigation [7].…”

“…The occurrence of other manifestations of osteoarthrosis in Petersson and Redlund-Johnell's series is not reported, so some of the joints with narrow spaces might have radiographic signs of severe osteoarthrosis. Judging from previous studies [7], it is unlikely that a normal acromioclavicular joint surface would have a cartilage layer of less than 1.0 mm. This corresponds to a radiographic joint space under compression of 2 mm.…”

“…The film used was high resolution, Kodak R1. The radiographs from the acromioclavicular joint with the arm hanging down were categorised into one of five different grades of osteoarthrosis according to Collins [2] and with the same criteria as described in a previous paper [7].…”

“…Twenty-seven percent were vertical and in 3% the articular surface of the clavicle underrode the acromion. In a previous study of osteoarthrosis of the acromioclavicular joint, conventional radiography was compared to the macroscopic findings in 110 acromioclavicular joints [7]. Radiography was found to be inadequate for demonstrating slight or moderate osteoarthrotic changes.…”

Diminished space in the acromioclavicular joint in forced arm adduction as a radiographic sign of degeneration and osteoarthrosis

1992

The purpose of this study was to examine the acromioclavicular joint by radiography under forced arm adduction to demonstrate diminished joint space as a sign of cartilage degeneration and osteoarthrosis. A total of 192 right and left joints were investigated in 96 healthy working men. There were three main results from the manoeuvre: in 135 of the 192 joints the space was reduced, in 33 joints it was unchanged, and in 24 joints the joint space was increased. In 43 joints (22% of the total) a marked reduction of the joint space to 1 mm or less occurred during the manoeuvre; in the remaining 92 joints with space reduction the reduction was less pronounced. A narrow acromioclavicular joint space during forced adduction of the arm indicates cartilage thinning and may be interpreted as a sign of osteoarthrosis.
