To Evaluate the intra and interobserver agreement for these classification systems. Forty-eight posteroanterior wrist radiographs from patients with osteoarthritis due to scaphoid nonunion were evaluated at two occasions—in a 1 week interval—by five observers with different expertise—hand surgeons, hand surgery residents, orthopedic surgeons and orthopedic surgery residents. They rated osteoarthritis stages according to the above-cited systems. Kappa statistics were performed for measuring agreement. Unsatisfactory (Cohen’s Kappa
