We evaluated radiographs of the hands of 20 pianists. The radiologic manifestations arising from long-term stress and strain applied to the hands were recorded. The changes are characterized by: 1) alignment adaptation consisting of axial radial rotation of the digits, particularly the fifth but also the third and fourth, 2) degenerative changes at the distal interphalangeal DIP and metacarpophalangeal MCP joints, and 3) mechanical remodeling manifested as periostal thickening and flattening of the phalangeal tufts associated with sclerosis. These findings suggest the existence of an occupational entity which might be described as pianist's osteoarthropathy.
我们评估了20名钢琴家手部的X光片。记录了长期手部压力和劳损所产生的放射学表现。这些变化的特征为：1）排列适应性，包括手指轴向桡侧旋转，尤其是小指，第三和第四指也有；2）远端指间关节（DIP）和掌指关节（MCP）的退行性改变；3）机械性重塑，表现为与硬化相关的骨膜增厚和指骨粗隆变平。这些发现提示存在一种职业性病症，可称为钢琴家骨关节炎。
