Abstract
Abstract A device may be used either for holding the bones of the forearm adjacent the wrist after they have been set following fracture or for holding the bones of the forearm and the wrist during arthrodesis comprises a pair of elongate members. Each member comprises two longitudinally adjustable parts 21, 22 and two end clamps 27, 33 for a pair of Kirschner wires 29, 34. One end clamp 33 can move relatively to the part 21 without exerting any contracting force and the other end 27 is fixed to the part 22 and so is adjustable to effect positive extension and contraction. The part 21 may also carry a third Kirschner wire 36. The device is used for holding a set fracture by using the members with the wire 36 and only one or other of the wires 29 and 36 and for arthrodesis by fitting all three wires. <IMAGE>

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
162 words
A device for holding the bones of the wrist and forearm in positions to which they have been set after fracture or during arthrodesis of the wrist, the device comprising a pair of elongate members, each of adjustable length and each having individual adjustment means by which the length of the member can be adjusted, each member having adjacent the outer ends thereof clamping means for engagement with a pair of pins or wires which are to be passed transversely through the forarm and the ulna and the radius or portions thereof to project from opposite sides of the forearm and the ulna and the radius or portions adjustable by said adjustment means to hold the pair of pins or wires in required relative positions and at a required spacing therebetween, as determined by the positions in which the bones or bone portions have been set or are to be held and the positions at which the pins or wires pass therethrough.
Claim 2
Independent Claim
162 words
A device for holding the bones of the wrist and forearm in positions to which they have been set after fracture or during arthrodesis of the wrist, the device comprising a pair of elongate members, each of adjustable length and each having individual adjustment means by which the length of the member can be adjusted, each member having adjacent the outer ends thereof clamping means for engagement with a pair of pins or wires which are to be passed transversely through the forarm and the ulna and the radius or portions thereof to project from opposite sides of the forearm and the ulna and the radius or portions adjustable by said adjustment means to hold the pair of pins or wires in required relative positions and at a required spacing therebetween, as determined by the positions in which the bones or bone portions have been set or are to be held and the positions at which the pins or wires pass therethrough.
Claim 3
Dependent Claim
81 words
A device according to Claim 1 and primarily intended for fixing set bones of the forearm adjacent the wrist after fracture, in which device, each member comprises a pair of relativeiyadjustable parts and the adjusting means acts therebetween only to extend the member, thereby to enable the member to act as a strut, and is adjustable to permit the member to be contracted but without exerting any contracting force between the ends thereof, whereby the member cannot act as a tie.
Claim 4
Dependent Claim
53 words
A device according to Claim 1 and primarily intended for effecting arthrodesis of the wrist, in which device each member comprises a pair of relatively adjustable parts, the adjusting means acting therebetween positively both to extend and contract the member, whereby each member can act either as a strut or as a tie.
Claim 5
Dependent Claim
167 words
A device according to Claim 1 in which each member comprises three parts, namely a centre part and two end parts providing the clamping means, one end part and the centre part being relatively adjustable and having first adjusting means acting therebetween only to effect extension between the centre part and said one end part and adjustable to permit said centre part and said one end part to be contracted but without exerting any contracting force between the centre portion and said one end part, and the other end part and the centre part being relatively adjustable and having second adjusting means acting therebetween to effect positive extension and contraction between said other end part and the centre part, the centre part of each member also having third clamping means thereon whereby a third pin or wire positioned between the other two pins or wires can be passed transversely through the ulna and the radius of the forearm and secured at its ends to third clamping means.

Claim 10
Independent Claim
49 words
A device which may be used either for holding the bones of the forearm adjacent the wrist after they have been set following fracture or for holding the bones of the forearm and the wrist during arthrodesis constructed in accordance with
Figures 3 and 4 of the accompanying drawings.
Claim 11
Independent Claim
49 words
A device which may be used either for holding the bones of the forearm adjacent the wrist after they have been set following fracture or for holding the bones of the forearm and the wrist during arthrodesis constructed in accordance with
Figures 3 and 4 of the accompanying drawings.
