[Follow-up of Patients Treated by Sliding Compressive Screws on Account of Fractures of the Head ot the Femur.].

The authors submit an analysis of a patient group treated in 1986 to 1987 by synthesis, using a dynamic sliding compressive screw produced in POLDI Kladno for fractures of the neck of the femur after an interval of cca 4, 5 years (interval 4-5 years) following synthesis. Apreliminary reports after cca 6.5 months following operation was submitted in 1988. From the original group of 26 operated patients four patients died during the follow-up period, seven were lost from the follow, three were reoperated because of early failure of the synthesis. An account of all three patients was presented in the previous communication. Another tree patients were treated by secondary alloplasty on account of sequelae of aseptic necrosis of the head of the femur, one patient waits for the same reason for implantation of a total endoprosthesis. At present eight patients have recovered and are satisfied with the operation. In patients with fractures of the neck of the femur within five years after synthesis the main problem as regards possible complications is aseptic necrosis of the head. Key words: fractures of the neck of the femur, dynamic compressive screw (DHS - dynamische Hufschraube, dynamic sliding screw).
