Abstract
Abstract The lumbrical bar includes a stem attached at its upper end to the longitudinal bar of a dorsal splint and a transverse pad at its lower end to provide support of one or more of the proximal or distal phalanges. The stem is adjustable to permit placement of the pad above or below the fingers without rotating the splint. The stem includes a narrow neck portion to permit extension between two adjacent fingers. A palmar pad or flexion cuff can be utilized with the bar to provide flexion of the fingers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
204 words
In a dynamic brace for metacarpophalangeal articulation reconstruction having a dorsal splint attachable to the forearm and extending to a point to be located with respect to the hand beyond the wrist for support thereof; a longitudinal bar mounted to said splint and having a portion spaced from said splint and extending therewith to a position to be over the hand; and a lumbrical bar attached to said longitudinal bar for supporting the metacarpal; the improvement comprising said lumbrical bar having a means at one end attaching said lumbrical bar to said longitudinal bar, a transverse pad at the other end of said lumbrical bar for supportive engagement of one or more of the proximal or distal interphalanges, said attaching means being adjustable to permit selection of the degree of extension of said pad along said longitudinal bar, and a stem portion extending from said attachment means to said pad, said stem including a narrow necked down portion that is thinner than the overall dimensions of the remainder of said stem extending from said pad and sized to permit comfortable positioning of said neckeD down portion between adjacent fingers whereby said pad is positionable proximally or distally against the bottom portions of said interphalanges.

Claim 3
Dependent Claim
28 words
The improved brace according to claim 1 wherein said transverse pad has a generally arcuate curvature, the radius of curvature extending vertically from a point beneath the pad.
Claim 4

42 words
The improved brace according to claim 1 wherein said stem is comprised of an upper and lower part slidably attached to each other to vary the length of said stem, said lower part including said neck portion at the lower end thereof.
Claim 5
Dependent Claim
44 words
The improved brace according to claim 1 wherein said brace further includes a pad secured to said splint for supporting the palm when said lumbrical bar is extended so that said transverse pad is adapted to be positioned beneath the metacarpophalangeal for support thereof.
