The authors present the reasons failed lumbar disc operations among 51 patients, 53% of them were womae and 47% were mae. Age of the patients was from 30 to 73 years (average 49 years). Most of them have had some operations. They complained of constant, strong lumbar pain with sciatic pain, restriction of lumbar spine mobility and paresis. The results were compared after 12 months from final operation with applying 3 methods: decopmpression, transpedicular fixation with decompression and decompession conected with transpedicular fixation and inerbody fusion. Intraoperatively considerable amount of instability (60%) was found. The best results of treatment was gained in decompression conected with transpedicular fixation and interbody fusion. The good result came up 41% in this group and in the other 20%.

Comparative study of the Ender method and Dynamic Hip Screw stabilization in the treatment of intertrochanteric fractures of the femur.

Background. The aim of this retrospective study was to compare the results of two fixation devices (Ender rods in 118 patients and dynamic hip screw in 98 patients) for treatment of intertrochateric fractures of the hip. Material and methods. The two treatment groups were similar with respect to important preoperative variables such as age, coexisting disseases, bone quality and incidence of stable and unstable fractures. The following outcomes were assessed: quality of reduction, length of hospital stay, early mortality, reoperations, persistent pain at a knee or hip, decrease in range of motion of the knee and leg shortening. Results and conclusions. The subgroup analysis showed higher incidence of complications in patients with unstable type of fracture treated with Ender nailing. These complications included mainly valgus angulation and malrotation of the fracture, need for a secondary procedure due to loss of stabilization and knee pain. Intramedullary stabilization with Ender rods is not recommended in treatment of unstable intertrochanteric fractures of the femur.
