We undertook a trial on 60 patients with AO 31A2 fractures of the hip who were randomised after stabilisation of the fracture into two equal groups, one of which received post-operative treatment using a non-invasive interactive neurostimulation device and the other with a sham device. All other aspects of their rehabilitation were the same. The treatment was continued for ten days after operation. Outcome measurements included the use of a visual analogue scale for pain, the brief pain inventory and Ketorolac for post-operative control of pain, and an overall assessment of outcome by the surgeon. There were significantly better results for the patients receiving treatment by active electrical stimulation (repeated measures analysis of variance, p < 0.001). The findings of this pilot trial justify a larger study to determine if these results are more generally applicable.
At the Test Laboratory of CITO five modern devices for transosseous osteosynthesis were studied to evaluate the fixation stability in comminuted fractures. Firmness was defined in compression, twisting as well as frontal and sagittal bends. In all planes the highest level of fixation stability was found in RAPFIS device. Design peculiarity of that device provided the additional increase of fixation stability by roads insertion into bone fragments at an angle and diminution of the bonefixative distance (console) that almost 3 times improve the fixation stability.
In 97 patients with fractures of femoral trochanteric zone the treatment was performed by transosseous osteosynthesis using Gorodnichenko rod device. The number of inserted rods depended on fracture pattern as well as presence or absence of osteoporosis. Experimental biomechanic study showed the firmness and stability of fixation achieved. Elaborated surgical technique ensured the precision of rods insertion, minimum traumatization of the surrounding soft tissues and bone, thus providing significant decrease of blood loss and shortening the duration of operation. In all patients including the elderly and senile patients aggravated by concomitant diseases the results were favourable. Good results were achieved in 84,5% and satisfactory in 15,5%) of cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
