[Periarticular calcinosis following implantation of total hip endoprostheses]

Different factors for periarticular calcification following total hip replacement were analysed in a follow up study. The extent and location was evaluated in accordance to classification of Arcq (1973) with a grid stencil. In 68.5% of 111 THR's calcification of different degrees were to obtain. Early calcifications were to find 2 weeks and in completed form 6 month after the operation in x-ray. The most frequent location was around the Trochanter major. In dependence of operation's term male patients are more affected than females. Age, diagnosis, former operations, typ of prosthesis, secretion of wound and postoperative complications seem to have no influence on periarticular calcifications.
