An apparatus for reducing a fracture of the metacarpal comprising: a foundation having a reducing portion overlying the dorsum of the hand adjacent to at least one metacarpal, and a support portion extending from said dorsum around the ulnar side of said hand and terminating in a support end; means for reducing the apex of said fracture, said means connected to said reducing portion and mounting at a lower end adjacent said hand a pressure distributing plate, said means adapted for adjustable advancement of said plate from a first position adjacent said reducing portion to at least one other position displaced from said reducing portion toward said dorsum of said hand; a flexible strap fixedly secured at one end to said reducing portion and adjustably secured at one end to said reducing portion and adjustably secured to another segment of said splint; a flexible connector attached on one side to said support end and having on a second side an eyelet adapted to receive said strap; adjustable means for securing said strap to said eyelet; and a set of projecting sections extending outwardly of the distal end of said support end, said connector being attached to said projecting sections.

Claim 9

An apparatus for reducing a fracture of the metacarpal comprising: a foundation having, a reducing portion overlying the dorsum of the hand adjacent at least one metacarpal of said hand and having therethrough a threaded aperture, said aperture surrounded by a strengthening shoulder, said reducing portion having a width of about one inch, a support end coplanar to the palm of the hand, having extending from a distal end thereof two projecting sections, said support end having a width in excess of two inches, and a support portion connecting said support end and reducing portion, the longitudinal cross section of said support portion having a C-shaped curve complementary to the curve of the ulnar side of the hand; a flexible connector attached along one side to said two projecting sections and having on a second side an eyelet; a flexible strap having a VELCRO segment, said strap being fixedly attached at a first end to said reducing portion, one type of said VELCRO being located on the outside of said first end of said strap and a complementary attaching type VELCRO being located on the remainder of said side of said strap, and strap sized to pass through said eyelet; a pressure plate having a U-shaped curve and being about one inch long; and a threaded shaft passing through said threaded aperture, said shaft movably mounting at an end thereof toward said support end said pressure plate, and mounting at its other end a knob.

Claim 10

An apparatus for reducing a fracture of the metacarpal comprising: a foundation having, a reducing portion overlying the dorsum of the hand adjacent at least one metacarpal of said hand and having therethrough a threaded aperture, said aperture surrounded by a strengthening shoulder, said reducing portion having a width of about one inch, a support end coplanar to the palm of the hand, having extending from a distal end thereof two projecting sections, said support end having a width in excess of two inches, and a support portion connecting said support end and reducing portion, the longitudinal cross section of said support portion having a C-shaped curve complementary to the curve of the ulnar side of the hand; a flexible connector attached along one side to said two projecting sections and having on a second side an eyelet; a flexible strap having a VELCRO segment, said strap being fixedly attached at a first end to said reducing portion, one type of said VELCRO being located on the outside of said first end of said strap and a complementary attaching type VELCRO being located on the remainder of said side of said strap, and strap sized to pass through said eyelet; a pressure plate having a U-shaped curve and being about one inch long; and a threaded shaft passing through said threaded aperture, said shaft movably mounting at an end thereof toward said support end said pressure plate, and mounting at its other end a knob.

Claim 11

A method for reducing a fracture of the metacarpal wherein said fractured portion extends above the normal location of said metacarpal in a direction toward the dorsum of a human hand, said method comprising: positioning a rigid foundation having a support portion extending from said dorsum around the ulnar side of said hand and terminating in a support end, the longitudinal cross section of said support portion being generally curved shaped and complementary to said ulnar side of said hand, said support portion terminating in a support end whose width exceeds the width of said reducing portion, said reducing portion having an aperture therethrough to receive a threaded shaft mounting at an upper end an adjusting knob and at a lower end whose width exceeds the width of said reducing portion, said reducing portion having an aperture therethrough to receive a threaded shaft mounting at an upper end an adjusting knob and at a lower end a generally rectangular pressure plate, slightly curved along its width; attaching said foundation to said hand using a flexible strap fixedly attached at one end to said foundation and adjustably attached to a flexible connector attached along one said to said support end and having on a second side an eyelet adapted to receive said strap; and adjusting said pressure plate in a direction toward said dorsum to a position at which said plate pushes said fractured portion of said metacarpal back into the position said metacarpal would occupy in a normal, unfractured state.

Claim 12

A method for reducing a fracture of the metacarpal wherein said fractured portion extends above the normal location of said metacarpal in a direction toward the dorsum of a human hand, said method comprising: positioning a rigid foundation having a support portion extending from said dorsum around the ulnar side of said hand and terminating in a support end, the longitudinal cross section of said support portion being generally curved shaped and complementary to said ulnar side of said hand, said support portion terminating in a support end whose width exceeds the width of said reducing portion, said reducing portion having an aperture therethrough to receive a threaded shaft mounting at an upper end an adjusting knob and at a lower end whose width exceeds the width of said reducing portion, said reducing portion having an aperture therethrough to receive a threaded shaft mounting at an upper end an adjusting knob and at a lower end a generally rectangular pressure plate, slightly curved along its width; attaching said foundation to said hand using a flexible strap fixedly attached at one end to said foundation and adjustably attached to a flexible connector attached along one said to said support end and having on a second side an eyelet adapted to receive said strap; and adjusting said pressure plate in a direction toward said dorsum to a position at which said plate pushes said fractured portion of said metacarpal back into the position said metacarpal would occupy in a normal, unfractured state.
