title: [Arthroplasty of the rheumatoid hand. Pre- and postoperative imaging with special consideration of biomechanical and pathobiomechanical aspects and its radiological evaluation].
abstract: Radiology plays a key role when the indications for arthroplasties of the hand and finger joints are determined and for the postoperative follow-up. On the one hand, the degree of inflammatory changes in all affected compartments is to be evaluated and graded; on the other hand, conventional radiograms allow for a first assessment of possible joint instability and impaired biomechanics. Both aspects influence the choice of the proper surgical therapeutic strategy. Osteolysis, deformity, fracture, prosthesis loosening or failure, heterotopic ossification, and foreign body-associated formation of granulation tissue are complications which can be detected on follow-up radiographs early on.
