April 26, 1955 N. s. HALE ETAL 2,706,982 SURGICAL SPINAL REDUCTION SPLINT Filed June 26, 1952 IN VEN TOR.
wad bra ale flfizizf/i 1 %5502Z United States Patent Ofitice 2,706,982 Patented Apr. 26, 1955 2,706,982 SURGICAL SPINAL REDUCTION SPLINT Application June 26, 1952, Serial No. 295,622 4 Claims. (Cl. 128-87) Our invention relates generally to splints and more particularly, to an improved spinal reduction splint.
The splint directed to this purpose in common practice consists of a pair of collars linked usually by four turnbuckles. One of the collars fits under the chin and base of the neck of the patient and the other rests on the patients shoulders. The turnbuckles are turned to separate the two collars, so to apply expansive force as between the head and shoulders.
This device, while compact and generally effective, has certain defects which make it generally objectionable to the wearer, and limitations w ich render its use impossible under some circumstances. For instance, other head injuries such as broken jaws, injured skulls, often accompany fractured spines. It is evident that the conventional splint above cannot be used in such cases. Other drawbacks are the high degree of discomfort which accompanies the wearing of these braces and the difiiculty of eating, drinking and speaking. Further, there is no way of obtaining precisely even exerted pressure as between the several turnbuckles, nor when a particular pressure is desired is there any Way of determining it.
There are spinal reduction techniques which are directed variously to the correction of some of these defects, but they do not meet the prime requisite of being ambulatory, involving most often a procedure for anchoring a patient in a fixed position to a bed while at the same time exerting a pull on the patients head.
Therefore, it is our primary objective to provide an ventional ambulatory splint in being suitable for use in a Wider range of circumstances, of being more comfortable in the wearing and permitting substantially normal eating and drinking and talking, of being more versatile in the direction and the force of pull and affording greater assurance that the direction of traction will be correct, and in making provision for the application of a constant and measurable tractive force.
Conspicuous advantages of our splint are its structural simplicity and strength, its wide range of adjustment, not
of head grasping procedures, and its firm connection with the shoulders of the patient.
Other objects and advantages of our invention will be apparent from the following description and drawings of a preferred embodiment thereof, of which Fig. 1 is a front elevation showing our splint as it is employed on a patient,
Fig. 2 is a side elevation showing the manner in which our splint is secured to a cast,
Fig. 3 is an isometric view of that portion of our splint which fits over the shoulder,
Fig. 4 is an enlarged elevation, broken away to a section in part, of the upper left portion of Fig. l, and
ig. 5 is a section which may be considered as being taken substantially along the line 55 of Fig. 4 looking in the direction of the arrows.
The illustrated embodiment of our invention is preferably made throughout of a stainless steel and consists shoulder, but the curvature of the straps may be changed by manual bending to fit the circumstances of differing cases. The straps are perforated at 14 for the reception of bolts 16. In practice, a person suffering, for example, a cracked cervical vertebra will be first encased in an inner portion 18 of a cast 20 which extends over the shoulders. This inner portion 18 should be built up into a relatively smooth curve over the shoulders to ensure the straps 10 fitting fiat against it. As was indicated above, the straps 10 may be bent to accommodate different cast shapes occasioned by different shoulder sizes.
The straps 10 with bolts 16 in place, heads inward, are then placed on the still wet and plastic cast, and the outer cast portion 22 added so as to embed the straps 10 firmly in the cast. The ends of the bolts 16 will protrude out of the finished cast.
A pair of base plates 24 which are slightly curved and perforated with holes to align with the outstanding bolt 16 ends comprise the next elements of our device. These members are adapted to be seated on the completed, but not fully set, cast and to be bolted thereagainst and to the straps 10 by bolts 16. The base plates 24 have outstanding transverse ears 26 perforated for the reception of another bolt or pin 28 formed centrally thereon.
The remainder of frame 30 amounting tangle. which are formed to have a right angle 34 therein by bending, welding, that the members part of the sides of the frame and on the angle, part of d seized tightly by bolts are tightened. addition to the tubular portion proper, fittings 44 secured to the lower end thereof by welding or other appropriate means which provide at their lower extremity spaced perforated ears 46 which, with the ears 26 and bolts 23, provide the means for attaching the frame to the base plates 24.
A cross-piece 48 constitutes the remainder of the frame, this member likewise being telescopically slidable in the opposing other ends of the frame members 32 or alternatively capable of being clamped by the clamping ends 37 thereof.
Generally centrally of the cross-piece 48 a clamp 50 is the cable 64 to the turnbuckle is accomplished by a clamp be grasped at any point to cable length.
a bar 78. end on the pins the hook 72 is secured, centrally located on Two arms 80 are adjustably mounted at one bar, and at the other end carry opposite attachment 82 which are imbedded directly in the skull bone. It will be evident, however, that a variety of head clamps or slings may be employed depending on the nature of the injury and the preferences of the physician.
The use of the device embodying our invention will be largely self evident from the above description. In the case of a person suffering, for example, a cracked vertebra, the initial step will probably be the attachment of the head clamp 74 of whatever description and the patient will be placed in a stationary traction device for the application of the cast 20 which, it will be noted, fits closely up under the chin and to the sides thereof to inhibit movement of the head, but sufficient clearance is allowed so that there is no pressure or even direct contact between the head and cast. At a time when the cast however, sufficient to con 10 with the bolts 16 in place are bent to conform to the inner cast portion and placed thereon over the shoulders. The outer portion 22 is then added to complete the cast, the straps being completely and firmly embedded therein and the end of the bolts 16 protruding therefrom. Before the finished the base plates 24 are bolted to the protruding bolt ends 16 and drawn down against the cast to form firm seats for the plates in that part of the cast between the straps and plates. The cast is then permitted to set and dry.
After it has properly set, the frame is attached to the base plates 24 by bolts 28, the necessary adjustments being made in the telescoping joints 37 associated with the cross-piece 48 to fit the spacing of the plates 24 and to locate as desired the pulley 54 centrally or elsewhere within the frame 30. Likewise the joints 37 in the sides of the frame are adjusted to bring the cross-piece as close as possible to the patients head for convenience in wearing while at the same time leaving sufficient space for the clamp, hook and cable under circumstances of maximum desired traction. The telescoping joints are then tightened to make the frame fixed and rigid. To conclude the process, the hook 72 is secured to the head clamp 74, the cable 64 is adjusted in the clamp 66 to remove any excessive slack therein, and the turnbuckle 62 is tightened to effect the desired degree of traction on the head, the tractive force being readable on the spring scale 60.
In this fashion is provided a traction device which possesses all the advantages mentioned above and which is capable of employment in a wide variety of circumstances. It is of course understood that we do not desire to be limited by the specific disclosure herein. Many modifications are possible among which might be mentioned entraining and enclosing the cable, scale, and turnbuckle within the tubular frame members 30, the members having openings to permit adjustment and reading of the device. The limitations of our invention are set forth in the following claims:
