Microfracture pick for femoral head

1. A microfracture pick system for repairing cartilage on a femoral head, comprising:

a handle having a proximal end and a distal end;

an arcuate arm shaped to extend from the distal end of the handle and adapted to extend around the femoral head, the arcuate arm having a distal tip extending toward the handle along a longitudinal axis of the handle; and

an impaction member at the proximal end of the handle;

wherein the impaction member is a strike plate extending transversely from the proximal end of the handle.

2. The system of claim 1 , wherein the arcuate arm is formed along an arc defined by a circle having a diameter of about 10 centimeters (cm) to about 28 cm.

3. The system of claim 2 , wherein the arcuate arm is defined with a shallow angle and receivable within a cannula for performing a minimally invasive procedure.

4. The system of claim 3 , further comprising a retractable tip.

5. The system of claim 4 , wherein the arcuate arm has a slot in a sidewall and a bore in communication with the slot, the bore defined from the slot to the distal tip, and the retractable tip is slideably received in the bore, with a portion of the retractable tip extending through the slot.

6. The system of claim 5 , wherein the retractable tip further comprises a slider that extends through the slot, the slider manipulable to move the retractable tip between a first position and a second position.

7. The system of claim 6 , wherein the retractable tip further comprises a pointed tip, and in the first position, the pointed tip is wholly contained within the bore, and in the second position, the pointed tip extends beyond the arcuate arm.

8. The system of claim 1 , wherein impacting the impacting member yields a force in a direction of the distal tip towards the handle.

9. The system of claim 1 , wherein the impaction member is a slap hammer having a shaft, a proximal stop, and a collar, the shaft extending from the proximal end of the handle along the longitudinal axis of the handle and the collar operable to slide along the shaft to impact the proximal stop.

10. A microfracture pick system for repairing cartilage on a femoral head, comprising:

a handle having a proximal end and a distal end;

an arm having a proximal end coupled to the distal end of the handle and a distal tip extending toward the handle along a longitudinal axis of the handle, the arm defining a slot and a bore in communication with the slot, the bore defined from the slot to the distal tip;

a retractable tip slidably received in the bore, with a portion of the retractable tip extending through the slot and operable to move the retractable tip from a first position to a second position; and

an impaction member coupled to the proximal end of the handle.

11. The system of claim 10 , wherein the arm is sized to be positioned through a cannula.

12. The system of claim 10 , wherein the retractable tip includes a slider at a proximal end and a pointed tip at a distal end, and the slider extends through the slot to enable the retractable tip to be moved between the first position and the second position.

13. The system of claim 12 , wherein in the first position, the pointed tip is contained wholly within the arm, and in the second position, the pointed tip extends beyond the arm.

14. The system of claim 12 , wherein the pointed tip has a diameter between about 2 millimeters (mm) to about 3 mm.

15. The system of claim 10 , wherein the impaction member is a strike plate extending transversely from the proximal end of the handle.

16. The system of claim 10 , wherein the impaction member is a slap hammer having a shaft, a proximal stop, and a collar, the shaft extending from the proximal end of the handle along the longitudinal axis of the handle and the collar operable to slide along the shaft to impact the proximal stop.
