Abstract
A prosthetic system includes a movable joint defining at least one gap, and at least one spacer unit positionable in the at least one gap. The at least one spacer unit includes a resilient element that is controllably deformable to vary a thickness of the at least one spacer unit to fill the at least one gap, and to reduce the likelihood of the at least one spacer unit interfering with relative movement between components of the movable joint. The at least one material forming the resilient element is compressible in a first direction with little or no expansion in a second direction normal to the first direction.
Claims20
A prosthetic system comprising:
- a movable joint defining at least one gap;
- and
- at least one spacer unit positionable in the at least one gap, the at least one spacer unit including a resilient element formed of at least one material that is controllably deformable to vary a thickness of the at least one spacer unit to fill the at least one gap, and to reduce a likelihood of the at least one spacer unit interfering with relative movement between components of the movable joint, wherein the at least one material forming the resilient element is configured to compress in a first direction with little or no expansion in a second direction normal to the first direction.
A prosthetic system comprising:
- a movable joint defining at least one gap between first and second components;
- and
- at least one spacer unit positionable in the at least one gap, the at least one spacer unit including a resilient element formed of at least one material that is controllably deformable to vary a thickness of the at least one spacer unit to fill the at least one gap, and to reduce a likelihood of the at least one spacer unit interfering with relative movement between the first and second components, wherein the at least one material forming the resilient element is compressible in a first direction with little or no expansion in a second direction normal to the first direction.
A spacer unit comprising:
- a body positionable in at least one gap defined by a movable joint of a prosthetic system, the body including:
- a resilient element formed of at least one material that is controllably deformable to vary a thickness of the body to fill the at least one gap;
- and
- at least one rigid element attached to the resilient element and arranged to form a bearing surface between the movable joint and the body and to direct forces away from the resilient element, wherein the at least one material forming the resilient element is compressible in a first direction with little or no expansion in a second direction normal to the first direction.
