THE ANTERIOR SPLINT OF DR. NATHAN R. SMITH, OF BALTIMORE, MD. BY EPHRAIM CUTTER, M.D. OF WOBURN. This splint is brought forward under the conviction that it possesses features new and worthy the attention of the surgeon. It is a recent production of its distin- guished inventor, and was obtained, by the writer, on a late visit to Baltimore. It is intended for fractures of the lower extremities, and presents the following pecu- liarities : - (1) It is made of iron wire. (2) It is applied to the anterior surface of the limb. (3) It is a suspensory splint. (4) The splint does not touch the limb. (5) It may be bent to different angles, thus giving re- lief by shifting the obtuseness or acuteness of the inclina- tion of the leg with the thigh. (6) The counter-extension is effected by the weight of the body-the extension by the obliquity of the suspen- sory cord. (7) It is simple. (8) It is easy. (9) It is cheap. 12 DR. N. R.

There are two sizes. The larger (for the thigh) is about 4 feet long and 3 J inches wide. The smaller (for the leg) is about 2| feet by 3 inches. The first is made by bending on itself at two right angles a wire, as above, 8 feet and 7 inches in length. It is then crossed by 8 transverse pieces | inch in diameter, four of which are provided with eyes for the insertion of hooks. These bars are segments of a circle, in order to give a convex surface to the splint. The bars with eyes are movable. The smaller splint is similarly made, but with a shorter wire and with two bars having eyes. Fig. II. b I® £ wa Mechanical drawing of the anterior splint for the leg, viewed from above.

It is applied not to the posterior or lateral portions of the limb, but, as the name indicates, to the anterior sur- face. It is, in fact, an inclined plane, like many other splints; but it is an anterior, not a posterior inclined plane. For use, it is bent at three points - at one end to about a right angle, to fit the back of the foot and leg; at another point, near the middle, to an obtuse or acute DR. N. R. SMITH'S ANTERIOR SPLINT. 13 angle, to adapt itself to the obliquity of the limb at the knee joint; and at a third point, near the other end, to suit the angle made with the trunk by the thigh. (3) It is a suspensory splint. This feature is striking, but not original. By means of a cord provided with two hooks, which are inserted into the eyes made in the trans- verse bars of the splint, a loop is formed. This is attach- ed to another cord depending from some support over head, generally the ceiling. This cord, by a simple con- trivance (a block of wood bored with three holes through which the string passes), is lengthened or shortened till the limb is elevated sufficiently, or to gratify the patient with a change. The limb is thus hung in air. (4) The bandages whereby the member is confined to the splint, alone come in contact with the limb. Thus a perfect adaptation to the inequalities of the leg is at- tained, and a uniform support is ensured by the sling so made. (5) The metallic nature of the splint admits of a change in its angles. It is sometimes a relief to the patient to have his limb supported in different positions. An obtuse angle of the leg and thigh may with comfort be made an acute one, and vice versa. This is done in the present instance simply by bending the splint. The same indica- tion is fulfilled in Roe's posterior inclined splint by means of a screw. (6) The counter-extension is made by the weight of the body, the extension by the suspending cord. The more oblique the direction of suspension, the greater the extension. By raising the foot of the bed, the patient will tend to move towards the head, and thus the counter- extension is increased. (7) It is simple. A man of common ingenuity can fashion one. A piece of wire is merely bent on itself at 14 DR. N. R. SMITH'S ANTERIOR SPLINT. two right angles and fitted with cross-bars. The eyes in the bars are made by one turn of the wire on itself. (8) Its ease is considerable. The patient can move in bed. He can sit up. He is made portable without dis- placing the fracture - for by keeping the limb suspended by the cord in the hand, an assistant can lift the patient from his bed without trouble. The writer saw a man with fracture of the thigh at the middle third, of three weeks standing, removed from his bed in the ward and conveyed to a clinical amphitheatre some distance off, without inconvenience - his limb being supported by this splint, in the manner just mentioned. The patients treated expressed satisfaction with the splint. (9) It is cheap. Mr. Taylor, a wire-worker of Balti- more, furnishes the splints for $1.00. This gentleman stated that it was adopted in the U. S. Navy, and that he provided the government with brass models for ships. The splints are no longer an experiment. They have been used in Baltimore for two years. Mode of Application. - Having bent the splint to fit the limb, and arranged the suspensory cords, the surgeon covers ^he splint with bandages and attaches it to the apparatus of suspension. The limb is then confined by adhesive straps passing round the splint at the ankle, knee and thigh, assistants also affording support. Rollers are then applied, the adhesive straps removed, and the opera- tion is complete. DR. N. R. SMITH'S ANTERIOR SPLINT. 15 The thigh splint in situ.
