Kinematyka stawu skokowego w trakcie chodu u pacjentów po operacyjnym usztywnieniu stawu

Background: Osteoarthritis, which causes pain, deformities and instability of the rearfoot, is the most common indication for ankle arthrodesis. The aim of this study was to present the influence of the ankle arthrodesis on the performance of this joint in the three planes during walking at natural velocity. Materials and methods: Fourteen patients, age from 34 to 66 years (mean: 54 years), with ankle arthrodesis participated in the testing procedures. Angular changes of the ankle in the three planes of movement during particular gait phases and spatiotemporal gait parameters were evaluated by a three-dimensional motion analysis system, Vicon®. The study was performed at the Biokinetics Laboratory of the Academy of Physical Education in Kraków. The results of locomotion analysis were compared to a control group, consisting of thirty healthy persons aged 40-65 years. Results: In the saggital plane feet joints worked symmetrically during all gait phases, but there were angular changes of plantar and dorsal flexion, which were different from biomechanical norm. In frontal plane, feet were in abduction during almost all gait phases. In the transversal plane, feet were in internal rotation. Significant differences in spatiotemporal gait factors were observed between the two groups. Conclusions: Ankle arthrodesis leads to significant changes in motion pattern of the ankle joints.Wstęp: Celem badań jest przedstawienie wpływu zabiegu artrodezy stawu skokowego na trójpłaszczyznową pracę stawu w trakcie chodu z naturalną prędkością. Materiał i metoda: Badania zostały przeprowadzone u 14 chorych wieku od 34 do 66 roku życia (średnia wieku 54 lata), u których przeprowadzony został zabieg artrodezy prawego stawu skokowego. Oceniane były zmiany kątowe stawów skokowych w trzech płaszczyznach ruchu w poszczególnych fazach chodu oraz parametry czasowo-przestrzenne chodu. Wyniki badań lokomocji zostały przedstawione na tle grupy porównawczej 30 zdrowych osób w przedziale wieku 40-60 lat. Wyniki: U badanych osób odnotowano zmianę schematu pracy w trzech płaszczyznach ruchu w porównaniu z wykresami grupy kontrolnej. Wnioski: W wyniku operacyjnego usztywnienia stawu skokowego dochodzi do istotnych zmian wzorca ruchowego stawów stopy

Wpływ usztywnienia stawu skokowego na funkcjonowanie stawów kolanowych i biodrowych w trakcie chodu z naturalną prędkością

Wstęp: Celem badań jest przedstawienie wpływu zabiegu usztywnienia stawu skokowego na prawidłowe funkcjonowanie stawów kolanowych i biodrowych w trakcie chodu z naturalną prędkością. Materiał i metoda: Badania zostały przeprowadzone u 14 chorych w wieku od 34 do 66 roku życia (średnia wieku 54 lata), u których wykonano zabieg usztywnienia prawego stawu skokowego z wykorzystaniem systemu do trójwymiarowej analizy ruchu Vicon 250. Oceniane były zmiany kątowe stawów kolanowych i biodrowych w trzech płaszczyznach ruchu w poszczególnych fazach chodu. Wyniki lokomocji zostały przedstawione na tle grupy porównawczej 30 zdrowych osób w przedziale wieku 40-60 lat. Wyniki: U badanych osób odnotowano zmianę schematu pracy stawów kolanowych i biodrowych w trzech płaszczyznach ruchu w porównaniu z wykresami grupy kontrolnej. Największe odchylenia od normy biomechanicznej stwierdzono w płaszczyźnie czołowej i poprzecznej w stawach kolanowych oraz w płaszczyźnie strzałkowej i poprzecznej w stawach biodrowych Wnioski: Zabieg operacyjnego usztywnienia stawu skokowego ma wpływ na funkcjonowanie stawów kolanowych i biodrowych w trzech płaszczyznach ruchu.Background: Ankle arthrodesis is probably still the safest method of treating painful, lesioned ankle in patients with rheumatoid arthritis or osteoarthritis with significant symptoms that do not respond to conservative treatment. The aim of this study was to present the effects of the ankle arthrodesis on correct functioning of the knee and hip joints during walking at natural velocity. Materials and methods: The study was conducted in the Biokinetics Laboratory of the Academy of Physical Education in Kraków. Fourteen patients with ankle arthrodesis, aged from 34 to 66 years (mean: 54 years), were enrolled into the study and participated in the testing sessions. Angular changes of the knees and hips in three planes of movement during particular gait phases were evaluated by a three-dimensional motion analysis system: Vicon®. The results of locomotion analysis were compared to a control group that consisted of thirty healthy persons aged 40-60 years. Results: Significant differences in the movement of the knees and hips in the three planes of motion were observed between the two groups. In the frontal plane, knees moved symmetrically, but during all the gait phases, knees were in a significant valgus deformity. In the transversal plane, knees were in a significant external rotation during all gait phases. In the saggital plane, hips moved with limited extension. There was also a significant external rotation, outside the biomechanical normal range, of both hips in the transversal plane. Conclusions: The most significant deviations from the biomechanical normal range were found in the frontal and transversal planes for knees and in the saggital and transversal planes for hips
