Abstract

Abstract A splint for setting a COLLES' fracture is formed of a pair of relatively shiftable elements (12, 63). The first an elongated support element (12) preferably made of plastic and transparent to x-rays. A travelling block (30), with holes for a first set of pins (103) is shiftable along the length thereof through a first worm and rack, allowing for distraction of the radius. The second element (63), with holes for a second set of pins (104) is pivotally mounted on the proximal end of the first element (12) throuth a second worm and rack. Once the splint is mounted on the forearm, the pivotal axis (42a) of the two elements (12, 63) coincides with the rotational axis of the fracture site itself (135), so that rotational adjustment of the two elements carries hand, wrist and distal bone fragment (137) about the same axis, thereby improving rotational and appositional adjustment at the fracture site. A modified traveling block provides the capability of selectively moving hand, wrist and distal bone fragment (137) in a radial and ulnar direction as well as for selective extension and flexion of the wrist.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 115 words
A fracture splint comprising: an elongated first element having means shiftably mounted thereon for securing first pin means thereto, the first pin means adapted to be inserted into a bone of a patient on one side of a bone fracture; a second member pivotally mounted on said first element near the opposite end thereof, the second element having means thereon for securing second pin means thereto, the second pin means adapted to be inserted into the bone of the patient on the opposite side of said bone fracture, the axis of pivoting movement of the second element relative to the first element being at an angle relative to the longitudinal axis of the first element.
Claim 2
Dependent Claim 115 words
A fracture splint comprising: an elongated first element having means shiftably mounted thereon for securing first pin means thereto, the first pin means adapted to be inserted into a bone of a patient on one side of a bone fracture; a second member pivotally mounted on said first element near the opposite end thereof, the second element having means thereon for securing second pin means thereto, the second pin means adapted to be inserted into the bone of the patient on the opposite side of said bone fracture, the axis of pivoting movement of the second element relative to the first element being at an angle relative to the longitudinal axis of the first element.
Claim 3
Dependent Claim 35 words
A fracture splint as set forth in Claim 1, wherein said securing means for said first pin means has means thereon for moving the same in opposed directions along the length of the first element.
Claim 4
Dependent Claim 52 words
A fracture splint as set forth in Claim 1, wherein said securing means for the first pin means comprises a block shiftably mounted on the first element, and means coupled with the first element and the block for selectively moving the block in opposed directions along the length of the first element.
Claim 5
Dependent Claim 29 words
A fracture splint as set forth in Claim 3, wherein said block has a central passage therethrough, said first element being complementally received within and extending through said passage.
Claim 6
Dependent Claim 51 words
A fracture splint as set forth in Claim 1, wherein said first element has an elongated mounting member near said opposite end thereof, said mounting member being at an acute angle with respect to the longitudinal axis of the first element, said second element being pivotally mounted on said mounting member.
Claim 7
Dependent Claim 57 words
A fracture splint as set forth in Claim 1, wherein is included a ring gear secured to said first el ement and having a central axis coincident with the axis of pivotal movement of the second element relative to the first element, the second element having a worm journalled thereon and in mesh with the ring gear.
Claim 8
Dependent Claim 43 words
A fracture splint as set forth in Claim 1, wherein said securing means for the first pin includes a block shiftably mounted on the first element for movement longitudinally thereof, there being means on the block for defining a pair of pin-receiving holes.
Claim 9
Dependent Claim 47 words
A fracture splint as set forth in Claim 1, wherein said means on the second element includes structure for mounting a pair of spaced second pins thereon, the second pins being substantially coplanar with said axis of pivoting movement when the pins are mounted by said structure.
Claim 10
Dependent Claim 52 words
A fracture splint as set forth in Claim 1, wherein said means on the first element is mounted thereon and movable relative thereto in a direction transverse to the longitudinal axis thereof, and means coupled with the means on said first element for adjustably moving the same relative to the first element.
Claim 11
Dependent Claim 47 words
A fracture splint as set forth in Claim 1, wherein said means on the second element includes structure for mounting a pair of spaced second pins thereon, the second pins being substantially coplanar with said axis of pivoting movement when the pins are mounted by said structure.
