Surgical Experiences in South Africa, 1899-1900 / Being Mainly a Clinical Study of the Nature and Effects of Injuries Produced by Bullets of Small Calibre

by George Henry Makins

The only treatment indicated was a short period of rest, accompanied in the early stages by pressure and slight fixation, followed later by massage and movement if necessary.

Before dismissing this subject, I should like to particularly emphasise the fact, that in the cases described there was no reason to suspect the extension of fissures from the point of fracture in the shafts into the articular ends of the bones. This was as far as possible excluded by clinical examination, and in the cases where wounds of the soft parts only were present, the rapid return of the patients to active duty, with absence of remaining joint trouble, negatived the possibility of such fractures.

I only saw one case in which a longitudinal fracture actually extended for any considerable distance into a neighbouring joint. In this a comminuted fracture occurred just above the centre of the shaft of the humerus. At the time of examination and putting up of the fracture there was considerable swelling of the whole arm, and nothing special was noticed about the shoulder-joint. Three weeks later, however, when the fracture was consolidating, difficulty in abduction of the shoulder was noted, and the arm could not be placed closely in contact with the trunk. There was no evident displacement of the head of the humerus forwards. A skiagram, which I much regret I have not been able to insert, showed that a longitudinal fissure extended from the seat of fracture upwards in such a manner as to divide the upper fragment into two parts, of which the outer bore the greater tuberosity, the inner the articular surface of the head. The latter fragment had become somewhat displaced downwards, and had united in such a manner that the head rested on the lower part of the glenoid cavity. Abduction of the limb therefore brought the greater tuberosity into contact with the acromion process, and movement was checked. This case passed out of my observation shortly afterwards, and I have no knowledge of the final result as to movement.

Fractures of the bony processes surrounding the elbow-joint, and of the malleoli of the tibia and fibula, were not infrequent, but offered no special features.

One other form of injury indirectly affecting the joints is perhaps worthy of mention, but I observed it only once, and that in the case of the shoulder, the only joint where it is likely to be marked. I refer to the displacement of the head of the humerus by the force of gravity, when the circumflex nerve is injured. In the instance I refer to, a fracture of the surgical neck of the humerus was accompanied by complete motor paralysis of the deltoid and very rapid wasting of the muscle. Circumflex sensation was impaired, but not absent at the time the condition of the muscle was noted—a favourable prognostic sign of much importance. At the end of five weeks, when the fracture of the bone was consolidated, the head of the humerus had dropped vertically at least an inch, but could be replaced with ease. Shortly afterwards an improvement in the condition of the muscle commenced, and with this the head of the humerus was gradually raised. This patient later recovered his power in great part, but not completely.

In a few cases bullets lodged in the neighbourhood of joints in such positions as to limit movement by mechanical impact with the bones. Thus I saw one case in which a bullet lay between the radius and ulna just below the lesser sigmoid cavity; in another the bullet lay in front of the ankle-joint, and limited the possibility of flexion; and in a case related to me by Mr. Bowlby, a bullet was removed by him from the wall of the acetabulum where it was tightly fixed in the substance of the bone. In two other cases I saw bullets lying deeply on the anterior surface of the hip capsule and so limiting flexion. In all such cases the indication for removal of the bullet was sufficiently strongly marked.

Wounds of the Joints

These may be divided into several classes, varying much in comparative severity, and in prognostic importance.

1. The comparatively rare instances in which a wound implicated a joint cavity, without accompanying lesion of any bone.

2. Perforating wounds in which the bullet was retained within the articular cavity. These were also rare.
