I never saw any troublesome results from perforations of the carpus. The joints of the fingers also offered little special interest, except in so far as they afforded astonishing examples of the extreme neatness of the injuries which a small-calibre bullet can produce. Fig. 59 is a good example of such an injury.

Hip-joint.—I can only repeat with regard to this joint what I have already said as to the injuries to the head of the femur. I had practically no experience of small-calibre bullet injuries to the femoral constituent, and beyond the single case of injury to the acetabular margin mentioned on p. 193 I saw no obvious wounds of the joint at all.

The knee, as usual, proved itself par excellence the joint most commonly injured, no doubt as a result of its size, the extent of its capsule anteriorly, and its exposed position. In spite, however, of the frequency with which it suffered injury, and the opportunities it afforded for observation of the progress of the effusions towards absorption, the injuries to the joint gave less anxiety and attained a more favourable prognostic character than is the case in civil practice. This depended on the very favourable course observed in the frequent pure perforations following a direct line. These occurred in every direction, the accompanying hæmarthrosis usually disappearing completely in an average period of little over a month. The extremes can be fairly placed at a fortnight and six weeks. Limitation of movement was slight or non-existent in many cases; in others it was of a very moderate character, and I only remember to have seen one case in which a really serious anchylosis developed. In this the man was struck from a distance of 300 yards, and a considerable amount of bone dust from the femur was found in the lips of the exit aperture. The wounds healed per primam, but when I saw the man two months later anchylosis in the straight position was apparently complete.

The comparatively frequent association of popliteal aneurisms with wounds of the knee-joint has already been spoken of in relation to anchylosis. Wounds of the popliteal space from larger bullets sometimes caused more troublesome after-stiffness than wounds of the articulation itself. Again I remember a small pom-pom wound at the inner margin of the ligamentum patellæ without obvious wound of the joint, which was accompanied by synovitis from contusion, and was followed by very considerable limitation of movement. This had only been partially improved when the patient returned home, in spite of prolonged massage and passive movement.

The general remarks on the joints cover all that need be said as to suppuration of the knee-joint.

The ankle-joint maintained the undesirable character which it has always held as a subject for gunshot injuries. This is entirely a question of sepsis, and in great measure depends on the fact that the foot, as enclosed in a boot, is invested with skin particularly difficult to thoroughly cleanse; while the socks are an additional source of infection to the wounds before the patients come under proper treatment.

Of seven cases of suppurating ankle-joint, of which I have notes, only two retained the foot, and one of these after a very dangerous illness. This case was one of special interest as exemplifying the results dependent on variations in velocity on the part of the bullet. The patient was struck at a distance of twenty yards. The bullet entered the front of the right ankle-joint and emerged through the internal malleolus, just behind its centre, causing no comminution of the latter. It then entered the left foot by a type wound one inch behind and below the tip of the internal malleolus, traversed and comminuted the astragalus, and emerged one inch below the tip of the external malleolus. The first joint healed per primam. The second produced by the bullet when passing at a lower rate of velocity was accompanied by considerable comminution of the bone. It suppurated, and gave rise to great anxiety both for the fate of the foot and the life of the patient. It is probable that the more abundant hæmorrhage which took place from the second wound was in part responsible for the occurrence of infection.
