Abstract

The present invention relates to a device and method for supporting the first metacarpal bone and second metacarpal bone when the trapezium bone removed. A support is attached to both the first metacarpal bone and second metacarpal bone to support each bone.

Description

Carpal Metacarpal Support Device
Field of the Invention
[001] The present invention relates to a device and method for supporting the first metacarpal bone and second metacarpal bone when the trapezium bone has been removed.
Background of the Invention
[002] With some arthritic conditions it has been shown that the removal of the trapezium bone greatly reduces pain in the area of the hand between the base of the first metacarpal and second metacarpal bone. The problem with removing the trapezium bone is that it supports the first metacarpal and second metacarpal and without the support, one or both metacarpal bones may move out of position before scar tissue forms that would support them. This can necessitate the need for further surgical procedures.
[003] To keep the first and second metacarpal bones in position after trapezium removal, physicians have wrapped k-wire (usually about .045" in diameter) around the base of the first metacarpal and the base of second metacarpal to hold the bones in position. This is a time-consuming process because k-wire is difficult to bend and maintain in a proper position. It is also obtrusive. Another method to keep the first and second metacarpal bones in position is to drill aligning holes in the first metacarpal and second metacarpal and place a metal rod or screw therein to support both the first metacarpal and second metacarpal bone. The problem with this procedure is that it is timely, takes a relatively high degree of precision, and drilling through the first metacarpal and second metacarpal at an angle in the manner described can cause one or both metacarpal bones to break.
Summary of the Invention
[004] Embodiments of the invention relate to supporting the first metacarpal bone and second metacarpal bone when the trapezium bone has been removed, often because of an arthritic condition. The device includes a support sling that is comprised either of material that is gradually absorbed into the body or material that stays permanently within the body. Preferably before the trapezium bone is removed, the support sling, which may be a mesh material, is attached to the first metacarpal and the second metacarpal, preferably by screw bones to create a tight fit so the first metacarpal and second metacarpal are maintained in their normal position. Afterwards, the trapezium bone is removed. Brief Description of the Drawings
[005] Figure 1 shows support sling material that may be used in aspects of the invention.
[006] Figure 2 shows bone screws that may be used in aspects of the invention.
[007] Figure 3 shows the sling material of Figure 1 connected to the first metacarpal and the second metacarpal using the bone screws of Figure 2.
[008] Figure 4 shows the attached bones of Figure 3 after the trapezium bone has been removed.
Preferred Embodiments of Aspects of the Invention
[009] Turing now to the figures where the purpose is to describe preferred
embodiments of the invention and not to limit same, Figure 1 shows a support sling 10 that may be used in aspects of the invention. Any suitable, flexible material may be used. The support sling as shown may be biodegradable or be capable of being permanently retained in the body.
[0010] As shown, the support sling is 0.5 cm wide and 3 cm in length, although any suitable size material may be used. The support material may be a vicryl mesh although any suitable material may be used.
[001 1] The support sling 10 can be attached between the first metacarpal and the second metacarpal bones in any suitable manner, and is preferably attached by screws 2, which are self-tapping bone screws.
[0012] Figure 3 shows the support sling 10 attached (using screws 2) to the first metacarpal bone Ml and the second metacarpal bone M2. The support sling 10 is wrapped around and attached to the base of first metacarpal bone Ml and attached to the base and bottom of second metacarpal bone M2, so that the second metacarpal bone is supported.
[0013] Figure 4 shows the arrangement of Figure 3 with the trapezium bone removed. The support sling 10 attached to bone Ml holds both metacarpal bones in position until scar tissue can form to support them. Optionally, a substance such as a silicone implant or collagen filler may be added to the space where the trapezium was located.
[0014] Some examples of the invention:
