Current European Practice in the Treatment of Proximal Interphalangeal Joint Arthritis.

There are increasing numbers of proximal interphalangeal (PIP) arthroplasties performed in Europe. Meanwhile, most surgeons prefer arthroplasty over arthrodesis. Silastic arthroplasties remain the most widely used implants. The main disadvantage of the Silastic implants is the limited stability they provide. Correction of pre-existing deformation is difficult. Soft tissue handling and postoperative scarring have an influence on the results of PIP arthroplasty. Different surgical approaches are possible. The most popular approach in Europe is dorsal. Different surface replacement implants are on the market in Europe. The main advantage of these implants is the lateral stability provided through their more anatomic form.
