In the following study, the basal joint of the thumb and its neighboring joints of 100 anatomical specimens were inspected radiologically and macroscopically for arthrotic alterations. The comparison of the radiological and macroscopic findings showed that early arthrotic joint alterations cannot be diagnosed by radiograms. Virtually half of the specimens examined demonstrated arthrotic lesions of the basal joint of the thumb, whereas the trapezio-scaphoidal and trapezoido-scaphoidal joints were only affected in one-third of the specimens. Two-thirds of the cases with manifest arthrosis of the metacarpophalangeal joint of the thumb demonstrated additional arthrotic changes in the joints between the scaphoid, trapezium, and trapezoideum. No macroscopic evidence of arthrotic alterations in the remaining radial carpal bones were observed. The architecture of the capsular and ligamentous apparatus as well as the individual variations in the scaphoid bone have both been discussed as possible causes of these phenomena, as were polyarthrotic or secondary arthrotic processes.
