[Changes in collagen biosynthesis in patients with hip joint replacement surgery and reoperation].

The authors investigated the intensity of collagen synthesis in patients subjected to operation or re-operation of a total endoprosthesis of the hip joint. The patients suffered from osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. The authors assessed the activity of collagen glucosyl transferase (S-GGT) and the concentration of the N-terminal propeptide procollagen type III by two methods (S-Pro III-N-P and S-Fab) in serum before and after operation. A significant rise of S-GGT and S-Fab, as compared with controls, occurred only after operation while S-Pro III-N-P was elevated already before operation. S-GGT did not differ before and after operation, while N-propeptide concentration rose when either method was used.

[Surgical lengthening of the femur using the Poldi 7 device].

The work presents the evaluation of longterm results of the surgical prolongation of the femur. The examined group includes 10 patients: 5 boys and 5 girls which the authors treated in the years 1978-1986. Their average age in time of operation was 15.5 years. The youngest was 8 and the oldest 25 years old. Shortening was in 4 cases caused by poor healing of the fracture, in three cases it was a results of congenital hypoplasia of the femur or the whole lower extremity, in three cases it was caused by osteomyelitis. The duration of the prolongation was on average 4 months, the external fixation device was removed on average after 8 months. The mean prolongation was 8 cm, ranging from 4 cm to 11 cm. In 8 cases healing was without complications, twice there occurred a fatigue fracture which was treated by plate osteosynthesis.
