Abstract
A prosthetic joint is disclosed that includes a plurality of elements, which may be provided in kit form, that can be assembled to form either a single-axis joint or a double-axis joint depending on whether an adaptor is used to join first and second elements of the joint.
Claims18
A prosthetic elbow comprising:
- a humeral component;
- an ulnar component adapted to pivotably engage said humeral component;
- and
- an adaptor having a first end pivotably connected to said ulnar component and a second end pivotably connected to said humeral component.
1 more element
A kit assembleable in a first configuration to form a single-axis prosthetic joint or in a second configuration to form a double-axis prosthetic joint comprising:
- a first component having a proximal end insertable into a first bone and a distal end;
- a second component having a distal end insertable into a second bone and a proximal end;
- and
- an adaptor connectable between said first component and said second component;
- whereby said kit is assembled by connecting said first component directly to said second component to form a single-axis joint or by connecting said adaptor between said first component and said second component to form a double-axis joint.
2 more elements
A method of assembling a prosthetic joint comprising the steps of:
- providing a first joint component having a first end adapted to be inserted into the interior of a first bone and a second end;
- providing a second joint component having a first end adapted to be inserted into the interior of a second bone and a second end;
- providing a first connector for forming a single-axis pivotal connection between said first component and said second component;
- providing a second connector for forming a double-axis pivotal connection between said first component and said second component;
- selecting one of said first and second connectors;
- and
- connecting said first component to said second component using the selected one of said first and second connectors.
4 more elements
A double-axis prosthetic joint comprising
- a first component having a proximal end adapted to be mounted in a first bone and a distal end comprising a pair of spaced apart arms;
- a second component having a distal end adapted to be mounted in a second bone and a proximal end including a bore;
- a connector for pivotably connecting said first component to said second component comprising a first end having a bore pivotably mounted between said first component spaced apart arms and a second end comprising a pair of spaced apart arms, said second component distal end being pivotably mounted between said connector second end spaced apart arms.
A prosthetic joint kit comprising:
- a first component having a first end and a second end comprising a pair of spaced apart arms:
- a second component having a first end and a second end comprising a bore;
- a first connector for pivotably connecting said first component directly to said second component;
- and
- a second connector for pivotably connecting said first component indirectly to said second component.
2 more elements
A method of converting a single-axis prosthetic joint to a double-axis prosthetic joint comprising the steps of:
- providing a first joint element having a first end insertable into a bone and second end having a first shape;
- providing a second joint element having a first end insertable into a bone and a second end having a second shape complementary to said first shape, said second end being pivotably connectable to said first joint second end to form a single-axis prosthetic joint;
- providing a connector having a first end having a shape complementary to said first shape and a second end complementary to said second shape;
- pivotably attaching said first joint element second end to said connector first end;
- and
- pivotably attaching said second joint element second end to said connector second end to form a double-axis prosthetic joint.
