Early result of femur neck fracture treated with modular hemiarthroplasty fenix

: The aim of the study is clinical assessment of modular arthroplasty Fenix and early assessment of 77 patient with femoral neck fracture treated with Fenix hemiarthroplasty. The mean age of the group was 77 years. There were 51 woman and 16 men in the group. Size of the used steam and head, the way of steam implantation, time of the operation and early complication was assessed. Operated patients were evaluated with Harris Hip Score, Larson I and Larson II score. The most common used steams were number 3 and 4, and the most common used head was number 44 with -4 mm offset. Mean operation time was 68.9 minute. The following early complication occurs: superficial wound infection treated with antibiotics--8 cases, pneumonia--8 cases, urinary tract infection--6 cases, intra operative femur shaft fracture during steam implantation, treated with plate osetosynthesis--1 cases. There were 14 cases of death in the group. 22 patients were evaluated with HHS and Larson. Mean score in HHS was 71 point, in Larson I--76 point, in Larson II--72 point. There was found that operating technique is similar like in the others hemiarthroplasty system and system is easy to use. Most of the stems were cemented. There was found that there are a high percent of death in femur neck fracture patient group during the first year after the operation and this kind of fractures handicap patient locomotion in spite of good hip joint function.
