The proximal interphalangeal joint: arthritis and deformity

[摘要] Destruction of a proximal interphalangeal (PIP) joint is either a result of an inflammatory/degenerative process or is post-traumatic. It is a clinical diagnosis and is confirmed with conventional radiographic examination (Fig. 1). Patients classically present with swollen, tender PIP joints, with a more diffuse, swollen appearance and a fusiform joint contour. Joint stiffness is almost always present and often correlates with the degree of swelling. In specific post-traumatic instances at the PIP joint level, a computerized tomography (CT) scan may be useful to determine whether a joint-preserving procedure is warranted, such as an intra-articular osteotomy or joint reconstruction.
