Remarks on AETIOLOGICAL FACTORS IN OSTEO-ARTHRITIS OF THE HIP-JOINT

Abstract

With Special Plate) Osteo-arthritis of the hip is a condition which presents a characteristic clinical picture. When, however, the history and the pathological changes as seen in x-ray photographs are taken into account, it becomes clear that there are a number of different aetiological factors. The initial symptom may be pain or stiffness. The pain is most often felt in the groin or down the inner side of the thigh. Sometimes, however, it extends down the sciatic nerve, and occasionally at the onset it may be felt in the buttock or even in the back. There is progressive loss of movement characterized particularly by diminution of abduction and of inward rotation, and this eventually leads to a fixed deformity, the joint becoming adductcd, flexed, and rotated out. Finally, with complete fixation in this position, the pain tends to disappear. Most often only one hip-joint is affected, although not rarely both are involved.
