Upper tibial osteotomy of valgization in the treatment of genu-varum arthrosis [36 cases]

The authors report 56 cases of upper tibial osteotomy of valgization for gonarthrosis upon genu-varum in 32 patients whose mean age is 57 years. The initial angular deviation is assested from 5° to 30° [average: 12.4°]. The tibial osteotomy is realized by external closing in 33 cases, by internal opening in 3 cases and its fixation requires Blount's staples in 64% of cases. 18 patients are followed with an average recall of 4 years. The results are assested according anatomic and functionnel patterns. They are good in 52% of cases, average in 38% of cases and mediocre in 10% of cases. In the light of this experience and after the literature's review, the authors emphasize the different prognosis factors that permit electing the candidates for this type of surgery

[Osteosynthesis of trochanteric bulk fractures by lamina plate material [67 cases]]

The retrospective study of 67 cases of pertrochanteric fractures treated by AO material showed their particular superviness at a relatively young age [mean age = 60,5 years] in males [70%], Opposite to elderly females in western countries. Support after osteosynthesis has been precocious for stable fractures, and was not authorised until 2 to 3 months in instable fractures, the necessary time for consolidation. This discharge time had reduced mecanic complications rate to 3 minor cases and one case of intracephalic scanning with protrusion of the plate. In other aspects it has influence on mortality rate 4,5%, that remains small in comparison with surmortality in developed countries. Vital prognosis depends essentially on age and pre-operatory physiologic state and not precocious non limited support
