[Complications of synthesis using the Medin sliding compression screw].

In 1993-1999 in the Traumatological Hospital in Brno 141 syntheses DHS Medin were made in patients with fractures of the proximal femur. (Eighteen DHS syntheses of other manufacturers were also made. The latter were however not analyzed). During the primary operations twice revision was necessary on account of a technical mistake of the surgeon ad twice an early infection developed. Seven late complications occurred--4 times a pseudoarthrosis and three times an aseptic necrosis of the head of the femur. All complications were resolved by total replacement of the hip joint. In no instance failure of the implant was recorded.
