Abstract
There is provided a splint for supporting portions of bone to be set, the splint comprising first and second body-part engaging portions arranged with elastic bias there-between to provide support to portions of bone to be set and thereby in use hold the portions of bone to be set in place with a pressure above a predetermined minimum.
Description
Splint
The present invention relates to splints, in particular to splints to aid bone setting. The present invention also relates to associated methods of manufacturing a splint and to associated methods of supporting bone portions using a splint.
Providing a rigid plaster cast splint to externally support portions of broken bones and thereby aid bone setting remains a widely practiced technique. However, when applying a plaster cast it is sometimes difficult to hold the portions of bone to be set in the correct position while at the same time avoiding application of excess pressure. Further problems arise when soft tissue swelling surrounds the portions of bone to be set, as a subsequent reduction in swelling within a finished plaster cast can allow the portions of bone to move within the cast in a way that is undesirable. It is an aim of example embodiments of the present invention to address at least one disadvantage of the prior art, whether identified herein, or otherwise.
According to a first aspect of the present invention there is provided a splint for supporting portions of bone to be set, the splint comprising first and second body-part engaging portions arranged with elastic bias there-between to provide support to portions of bone to be set and thereby in use hold the portions of bone to be set in place with a pressure above a predetermined minimum.
In this way, the splint is able to accommodate a reduction in swelling around the portions of bones to be set while maintaining the pressure to the portions of bone to thereby hold the portions of bone in the correct position while healing occurs.
Suitably, the splint comprises a plastics material. Suitably, the body-part engaging portions are formed as one piece of flexible material. Suitably, the splint comprises a one-piece plastics form. Suitably, the splint comprises a heat-formable material.
Suitably, the body-part engaging portions are distributed along the splint and are arranged along the splint to extend in alternating directions away from one another. Suitably, the body- part engaging portions are arranged to wrap, or partially wrap around a body part, preferably a limb or limb portion. Suitably, the body-part engaging portions are arranged to partially wrap around a body part in alternating directions.
Suitably, the splint comprises first, second and third body-part engaging portions arranged with elastic bias there-between to provide three-point support to portions of bone to be set and
thereby in use hold the portions of bone to be set in place with a pressure above a predetermined minimum
Suitably, one of the first, second and third body-part engaging portions comprises a primary portion arranged to provide support proximate to the portions of bone to be set, and the others of the first, second and third body-part engaging portions comprise secondary portions arranged to provide support for the primary portions at a distance therefrom.
Suitably, the splint comprises a wrist splint. Suitably, the splint is arranged to support portions of bone from a distal radius fracture. Suitably, the predetermined minimum pressure applied to the site of the distal radius fracture corresponds to a force in the range 5-15N applied over the fracture site, preferably 10N. Suitably, the predetermined minimum pressure corresponds to that which a physician would typically apply when setting the portions of bone in a rigid cast. According to a second aspect of the present invention there is provided a method of manufacturing a splint, the method comprising: forming first and second body-part engaging portions and providing elastic bias there-between, such that in use the splint is arrangeable to provide support to portions of bone to be set and thereby in use hold the portions of bone to be set in place with a pressure above a predetermined minimum.
According to a third aspect of the present invention there is provided a method of supporting bone portions using a splint, the method comprising arranging first and second body-part engaging portions of the splint to provide support to the bone portions to hold the bone portions in place with a pressure above a predetermined minimum, as determined by elastic bias between first and second body-part engaging portions.
Suitably, the method employs the splint of the first aspect of the present invention or a splint manufactured according to the method of the second aspect of the present invention According to the present invention in other aspects there is provided an apparatus and method as set forth in any appended claims. Other features of the invention will be apparent from any dependent claims, and the description which follows.
For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings in which:
Figure 1 shows a perspective view from a first side and above a splint according to an example embodiment of the present invention, in use;
Figure 2 shows a perspective view from a first side and above a splint according to an example embodiment of the present invention, in use, this view from a lower point than that of Figure 1 ;
Figure 3 shows a perspective view from a second side and above the splint of Figure 1 , in use; and
Figures 4 and 5 show further perspective views of the splint of Figure 1 in use.
Referring now to Figures 1 to 5 there is shown a splint 1. The splint 1 comprises a wrist splint, and is shown in use arranged to support portions of bone formed by a distal radius fracture.
The splint 1 comprises first, second and third body-part engaging portions 1 1 , 12, 13 arranged with elastic bias there-between to provide support to portions of bone to be set. In this way the splint 1 holds the portions of bone to be set in place with a pressure above a predetermined minimum, even when swelling under the splint subsides or is reduced. The splint is able to accommodate a reduction in swelling around the portions of bones to be set while maintaining the pressure to the portions of bone. Maintaining pressure holds the portions of bone in the desired position while healing occurs, resisting any tendency of the bone portions to move within the splint 1.
The first, second and third body-part engaging portions 11 , 12, 13 are distributed along the splint 1 , and are arranged along the splint 1 to extend in alternating directions away from one another and generally perpendicular to the axial length of the splint 1. In use the body-part engaging portions 11 , 12, 13 partially wrap around a body part, here the wrist to provide three- point support to the portions of bone to be set. In other embodiments the body-part engaging portions may be provided in other arrangements to provide the support, for example in one or more loops or broken loops substantially encircling the body part of interest, and arranged unevenly along the length of the splint and unevenly between opposite sides of the splint.
The first body-part engaging portion 1 1 comprises a primary portion arranged to support at the fractured portion of bone to be set, and the second and third body-part engaging portions 12, 13 comprise secondary portions arranged to provide support for the primary portion 11. The secondary portions engage the wrist at a distance from the portions of bone to be set, and cooperate with the primary portion to provide the three-point support.
As shown in Figures 1 to 5, the splint, including the body-part engaging portions 11-13 is formed as one piece of flexible plastics material, and are heat-formed to provide the correct
size and deformation for the patient's personal requirements. In other embodiments the splint may be provided in a range of sizes, with the correct size from the range of sizes being selected according to the requirements of a patient. In such embodiments the process of heat- forming to provide conformance with the anatomy of a patient may not be needed at all, and the material used for such embodiments need not be heat-formable at the fitting stage.
Although the specific embodiment shown is a wrist splint comprising three body-part engaging portions, other embodiments are envisaged. For example embodiments comprising two, four or more body part engaging portions are envisaged. In particular, the example embodiments of the present invention may also be particularly suited to ankle fractures.
