Yasko Attorney-Harris, Kiech, Russell & Kern ABSTRACT: An ankle wrap for use with a splint and leg support members to provide a traction splint. An ankle wrap having five strap elements joined together, with first and second straps for wrapping a foot in overlapping relation, and fourth and fifth straps carried on a third strap for connection to the first and second straps to pull the first and second straps tight on the foot, and means for connecting the third strap to the splint and shortening the third strap to apply tension to the foot, while maintaining the foot in position 90 to the leg.

LEG TRACTION ANKLE STRAP This invention relates to traction splints for legs and in particular, to a new and improved ankle wrap for use in traction splinting. The Hare traction splint has been in use for some time as a leg splint, particularly in the emergency splinting of lower extremity fractures. The conventional traction splint includes an elongated U-shaped metal frame for receiving the leg, a plurality of leg support members positioned along the frame or splint and providing for supporting and retaining the leg in the splint, and an ankle wrap which engages the foot and includes means for attachment to the foot end of the splint. Means are also included for applying a tension force to the ankle wrap, pulling the patients foot toward the end of the splint against the restraining force of the ischial half-ring which is curved at the hip end of the splint and which butts against the ischium, thereby creating the desired traction in the patients leg.

A variety of arrangements have been utilized for ankle straps and tensioning and these prior art devices suffer from various shortcomings. It is highly desirable that the foot be maintained in a position substantially 90 to the leg. When tension is applied in the prior art ankle wraps, the foot is maintained in the forward or Equinus position. It is an object of the present invention to provide a new and improved ankle wrap which will maintain the foot in the desired 90 position while the leg is under traction.

Prior art ankle wraps have required separate tensioning devices, which devices usually require special configurations for the U-shaped splint. It is an object of the present invention to provide a new and improved ankle wrap which is a unitary structure requiring no separate tensioning unit and which does not require any specific configuration of the splint. It is a particular object of the invention to provide a new and improved ankle wrap which provides the traction force separate from the ankle gripping force.

Other objects, advantages, features and results will more fully appear in the course of the following description. The drawing merely shows and the description merely describes a preferred embodiment of the present invention which is given by way of illustration or example.

In the drawing:

FIG. I is a perspective view illustrating the use of the ankle wrap to provide a traction producing mechanism;

FIG. 2 is a plan view of an ankle wrap incorporating a preferred embodiment of the present invention; and

FIG. 3 is a perspective view illustrating a preferred form of connector means for the ankle wrap of FIG. 2.

The ankle wrap includes a strap 10, a strap 11 and a strap 12 joined together at a junction indicated generally at 13. In the preferred construction illustrated, the straps are of woven webbing and strap 12 is of double thickness, being looped over the straps l and II, with the three straps stitched together. A reinforcing pad 14 may be provided at the stitched junction area I3.

The straps 10, 11, 12 preferably are in a generally Y configuration as shown in FIG. 2, and the straps l0 and 11 may carry a soft pad 16 of rubber or plastic, typically urethane foam plastic. The strap I0 passes through slots in the pad 16 at l7, l8 and 19 and the strap 11 passes through slots at 20, 21 and 22 for retaining the pad in position. The pad 14 preferably is composed of Velcro hook material which provides friction and maintains immobility to the urethane foam pad 14, preventing the pad from slipping off of the webbing.

Straps 25 and 26 are joined to the strap 12 at an area indicated generally by 27 spaced from the area 13. The straps 25, 26 typically may comprise a single piece of webbing which is sewn to the strap 12 at the area 27, and preferably are oriented to provide a cross configuration.

A cooperating connector means is provided on the straps l0 and 26 for connecting the straps together to form a loop and for varying the size of the loop. Similarly, a cooperating connector means is provided on the straps 11 and 25 for connecting the straps to form a loop. A preferred form for the connector means is illustrated in FIG. 3.

In the connector means of FIG. 3, a metal hook 30 is fastened to the end of the strap 10 by a small strap 31 passing through a slot in the hook 30, with the ends of the small strap 31 sewn to the end of the strap 10. The strap 26 passes through spaced slots 33, 34 of a metal buckle 35. A pull tab 36 is sewn on the end of the strap 26, providing a larger gripping area and also preventing pulling the end of the strap 26 through the slots of the buckle 35. One edge of the slot 34 may be serrated, as seen in FIG. 3, to provide a better grip on the strap 26.

In operation, the hooked end of the hook 30 is passed through the slot 33 of the buckle 35 to form a loop. Then the end 36 of the strap 26 is pulled to shorten the loop to the desired size. The grip of the buckle 35 on the strap 26 may be released by pulling on another tab 40 which is fixed in another slot 41 of the buckle 35. This combination of buckles and hooks allows adjustability and attachment of the device to any size foot, shoe or boot.

The strap 12 extends beyond the junction area 27 and terminates in a mechanism for attachment to the splint. In the preferred embodiment illustrated, a metal grommet 43 is fixed in the end of the strap and an S-shaped hook 44 has one end positioned in the grommet, with the other end open for hooking over the splint.

The strap 12 includes means for adjusting the overall length thereof and preferably utilizes one of the buckles 35, with a portion 46 of the strap fed through the buckle in the same manner as the strap 26 of FIG. 3. The buckle 35 is attached to the main portion of the strap 12 at the junction area 27 by a short strap 50 which is passed through the slot 33 of the buckle 35 and sewn in with the straps 25, 26. The dashed lines, generally in a rectangular pattern with a cross therein, at the junction areas 13, 27 and at the ends of the straps indicate stitching or sewing. Of course, material other than webbing can be used for the straps as desired, and other methods of attaching may be utilized.

The use of the ankle wrap is illustrated in FIG. I, where the patients leg 60 is positioned in a conventional splint 61. The splint as illustrated comprises an elongated U-shaped frame 62, which may have a detachable U-bracket 63 for raising the foot end of the splint above the work surface. The splint 61 typically includes a ring and strap (not shown) for encircling the leg at the upper end of the thigh. A plurality of leg support members 65 are carried on the frame 62, each including an elastic strap 66 with a closure of some type for strapping the leg to the frame.

The patients leg is first on the splint, with the foot spaced from the end 68. The leg is then strapped in place by the ischial half-ring at the hip and the leg straps 65. The ankle wrap of FIG. 2 is then placed in position under the foot, with the junction area 13 at the back of the heel. The strap 11 is brought forward over the top of the foot and connected to the strap 25 and this loop around the foot is pulled snug. Then the strap 10 is brought over the top of the foot and connected to the strap 26 and the loop is pulled snug. Then both loops can be pulled as tight as desired, providing a firm grip on the foot adjacent the ankle.

The hook 44 may be engaged with the end 66 of the frame prior to or subsequent to placing the straps I0 and 11 around the foot. After the straps 10 and II are firmly in place and after the hook 44 is in place, the strap 12 is placed in tension by pulling on the end of the strap 46. This tensioning produces the desired traction on the patients leg.

The ankle wrap of the present invention is a unitary structure with no loose parts. The three principal straps I0, 11, I2 are individually adjustable for tension. The wrap provides for gripping and adjusting the grip on the patients foot independent of the adjustment of the traction via the tension in the strap 12. The unique arrangement of the straps and the adjustments thereof provides an ankle wrap and tension arrangement which maintains the patients foot substantially at relative to the leg, as seen in FIG. 1.

Although an exemplary embodiment of the invention has been disclosed and discussed, it will be understood that other applications of the invention are possible and that the embodiment disclosed may be subjected to various changes, modifications and substitutions without necessarily departing from the spirit of the invention.
