Abstract
A femoral head surgical resurfacing aid that includes a C-shaped band with an interior surface conformed to fit a femoral neck of a patient is presented. An arch extends from one side of the C-shaped band to the other side of the C-shaped band and further extends over a femoral head of the patient. An alignment tube guide is positioned along the arch and extends outward from the arch.
Claims7
A femoral head surgical resurfacing aid, comprising:
- a C-shaped band constructed of flexible material and defining an elliptical shape with an interior surface slightly smaller than a femoral neck of a patient and conformed to follow the surface of the femoral neck, the C-shaped band further defining an opening configured to enable the C-shaped band to be slipped over the femoral neck and be frictionally fixed in place on the femoral neck upon rotation of the C-shaped band and engagement of the elliptical shape with the cross section of the femoral neck, wherein the width of the C-shaped band substantially spans the femoral head-femoral neck junction and the greater trochanter-femoral neck junction;
- an arch integrally constructed as part of the C-shaped band of the same flexible material and defining a shape following the contour of the femoral head, wherein the arch is formed on opposite sides of the exterior of the C-shaped band and slightly back from the edges of the opening, the arch further extending perpendicular over the C-shaped band;
- and
- an alignment tube guide projecting perpendicularly outward from the top of the arch and extending axially away from the femoral head, wherein an outer diameter of the alignment tube guide matches a width of the arch and further comprises a “snap off” feature at the top of the arch.
