Recently fifteen cases, twenty-two joints, of neurogenic arthrosis have been experienced. Eighty per cent of them were older than fifty years of age, and the youngest was twelve years old boy. Five patients were male and ten were female. Six patients complained of mild or moderate pain in affected joints, but nine had no pain.Abnormal findings in the roentgenogram were observed in eleven knee joints (50%), three ankle joints, two lumbosacral joints, two hip joints, two shoulder joints and two elbow joints.Etiologically eleven cases (73.3%) were caused by tabes dorsalis, and the others were by syringomyelia, poliomyelitis, peripheral neuritis and unknown.In roentgenographic findings of the knee joints, there were noted lateral subluxation of tibial articular surface, periosteal thickness and marked bony changes, which were erosion or multiplication, at medial articular border of tibia and lateral articular border of femur in all cases.Analyzing dynamic actions in neurogenic arthrosis of knee joints on the bases of these findings, we assumed that erosion and multiplication of the bones were easily occurred at medial tibial condyle and lateral femoral condyle.
