Later on painfulness of the hip-joint is experienced from pressure and at about the same time the movements are impeded.
Then the leg takes a peculiar position. The thigh is slightly bent and rolls outward. For convenience the child drops the half of the pelvis corresponding to the diseased hip-joint, and naturally raises the other half. From this apparently a curvature of the spinal column results in the lumbar region. Apparently only, for when the child is laid down and the morbid position of the thigh is restored the curvature of the lumbar column disappears.
During the further progress of the disease the pain is increased, and the sensibility may become so acute that the slightest movement of the limb, even a shaking of the bed in which the patient lies will cause the most intense pain. In the previous stage walking could only be done for short distances and then awkwardly, now it is entirely impossible. Children are obliged to lie in bed night and day, and under these altered conditions there is a change of the position of the extremity. The increased sensibility induces the child to seek the medium position, the leg is bent more than in the position mentioned above, it is halfway straightened.
To this is added, that the child can not lie well on the sensitive and swollen hip; with right side hip-joint inflammation it turns on the left. As the diseased and bent thigh does not then rest on the mattress the same is placed on the healthy limb for support and for protection from movements, in the same manner as we lay one leg on the other in a healthy condition when we sleep on our side.
The actual danger to life in tuberculous hip-joint inflammation begins with the time when the child takes to his bed. The fatal end comes almost without exception after suppuration has commenced, very rarely before that time. Total suppuration of the hip-joint is an almost absolutely fatal process. If this suppuration sets in suddenly, it may result in an early death with attendance of acute fever. In other cases several weeks may elapse from beginning suppuration till death.
A complete cure of tuberculous hip-joint inflammation may come about spontaneously. But often the knee remains bent and unserviceable for walking, so that crutches or machines must be used.
Even before this the beginning stages were treated with fair prospects of success, and it is a lamentable fact that in many cases the import of these seemingly trivial symptoms has been underestimated.
Rest is of the greatest importance during the very first stages of the disease in which the attending symptoms are of so indefinite a character that it is almost impossible to know whether hip-joint inflammation will develop or not; the child must not be allowed to walk. Aside from this the application of brine-, malt- and sea-water baths is advised. An abundance of nourishing food is of just as great importance. All this will also retain its significance in the future.
Formerly recourse to surgery has been taken during the later stages of the disease in which suppuration of the internal parts of the joint has commenced and large parts of the diseased bones may have become mortified. An incision is made into the joint, the same is exposed and all diseased portions are carefully removed. In the future this operation must probably also be performed, although with the difference that the prospects of success are now much more certain than formerly when relapses only too often followed the operation.
Tuberculous inflammation of the knee-joint is, as said before, very frequent with children and is rather lingering in the beginning. Here also a slight dragging or limping of the diseased leg can be noticed. The child when asked about the limping, or of its own accord, complains of pain in the joint after walking or when the part is pressed; at first nothing abnormal can be seen on the knee by the layman.
