. A practical treatise on fractures and dislocations . Huntons yoke splint, modified by Day. Front view of Welchs apparatus. Fox, Listons Practical Surgery, Amer. ed., p. , Sargents Minor Surgery, p. 132. FRACTURES OF THE 45. 197. Back View of Welchs Apparatus.—X Vertical or dorsal piece. 6, 6. Lateral or thoracic arms, c, or cervical arms, d, d. Transverse or acromial arms, e, e. Leather shoulder-caps and straps. The frame, consisting of the dorsal piece with the thoracic and cervical arms, is formed of flexiblemetal, which yields sufficiently to adapt it always to the motions of the spine and chest. The lateralor thoracic arms encircle the body, and the vertical or cervical arms, passing upwards, outwards, andforwards, conform to the sides of the neck. The whole are well and thickly padded. The transverse or acromial arms, running parallel with the spine of the scapula to the acromion pro-cess, are made of elastic steel, slightly curved backwards at their outer extremities, so that, when theshoulders are made fast to them by the shoulder-straps, they will tend constantly to pull the shouldersoutwards and backwards. The several parts of the apparatus are adjusted to persons of different sizes. 1st.
