Several cases of suppuration which came under my notice did well. I saw one of them a few days ago, six months after the injury, with perfect movement. In another of which I took notes, the bullet entered over the outer aspect of the head of the radius, to emerge just above the internal condyle anteriorly. A considerable amount of comminution of the olecranon resulted, and when the man came into hospital some ten days later the joint was suppurating. The joint was opened up from behind, and some fragments of bone removed by Mr. Hanwell. On the 26th day this joint was doing well, and considerable flexion and extension were possible without pain. There was a somewhat abundant discharge of bloody synovia during the first few days after the operation. [Illustration: FIG. 59.--Illustrates the very neat and limited injury to the Phalanges over the dorsal aspect of the first inter-phalangeal joint of the Middle Finger, accompanying a gutter wound received by the patient while holding a rifle.] 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 haemarthrosis 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.
