Summary
The present is a long-term follow-up study of patients who underwent triple arthrodesis for a variety of pathologic alterations. Utilizing a new method for both the qualitative and quantitative measurement of foot-ground pressure patterns, these patterns were recorded in forty control feet and twenty-six operated feet. In the patient group, less equal distribution of body weight between both feet was observed in comparison to the control group. In the latter, the main load underneath the foot was distributed underneath the forefoot and heel, while in the patient group, this load distribution had persistently shifted to the midfoot and heel, thus producing a completely different foot-ground pressure pattern. Furthermore, under the forefoot, the main load was located under the medial two rays in the control group, shifting towards the lateral rays in the patient group. The talo-navicular joint had the highest rate of non-union, but no positive correlation between that finding and persistent pain was found. Feet affected by neurological disorders often became pain-free following surgery, but none of the patients showed such post-traumatic relief.
Zusammenfassung
Die Verteilung des Fußbodendruckes bei vierzig normalen und sechsundzwanzig operierten Füßen wurde qualitativ und quantitativ untersucht und verglichen. Die Patientengruppe bestand aus Fällen, bei welchen eine Arthrodese der subtalaren Gelenke zwischen 1958 und 1976 für verschiedene Pathologien vollzogen wurde. In der Patientengruppe zeigte der Fußbodendruck eine weniger symmetrische Verteilung zwischen den beiden Füßen, während am Fuß selbst die Druckverteilung bei der Patientengruppe einen völlig anderen Auswurf zeigte. Die Unterschiede zwischen den beiden Gruppen waren statistisch höchst signifikant. Das talo-naviculare Gelenk bewies den höchsten Prozentsatz von Pseudarthrosen, jedoch keine positive Korrelation zwischen Fußschmerzen und dieser Pseudarthrose. Füße, die wegen neurologischer Krankheiten operiert wurden, waren nach der Operation oft schmerzfrei, während post-traumatische Füße nie schmerzfrei wurden.
