  		Fig. 2. —75-year-old man with de Quervain tenosynovitis. Posteroanterior wrist radiograph shows focal radial styloid periosteal bone apposition and cortical erosion (arrow). One observer graded this finding as "definitely abnormal"; the other, as "equivocal."

  		Fig. 3A. —70-year-old woman with de Quervain tenosynovitis. Posteroanterior wrist radiograph of symptomatic wrist shows cortical erosion and sclerosis (solid arrows) with adjacent soft-tissue swelling (open arrow). Note that soft tissues were masked at time of study. Each observer graded this finding as "definitely abnormal."

  		Fig. 5. —Graph shows receiver operating characteristic curves for finding focal radial styloid abnormality when diagnosing de Quervain tenosynovitis. Note that areas beneath receiver operating characteristic curves for each observer are not significantly different from each other and are significantly different from chance. {blacktriangleup} = observer 1, {diamondsuit} = observer 2, dashed line = no discrimination.
