Abstract
An orthopedic device that includes an ankle arthrodesis nail having a bend, and a surgical implant kit for use in ankle arthrodesis in patients who suffer from severe bone defects in their ankles is provided. The invention further relates to a method of establishing ankle arthrodesis in a subject using an arthrodesis nail having a bend.
Claims13
An ankle arthrodesis nail, comprising:
- a rigid round tibio-talo-calcaneal rod having a distal portion and a proximal portion, a bend in the distal portion, wherein the bend is configured to match an anatomic alignment of a hindfoot, the rod further comprising proximal and distal holes for locking screws, wherein the rod has a bend in the proximal portion, wherein the bend in the proximal portion and the bend in the distal portion create an offset between the ends of the nail.
A method of establishing ankle arthrodesis in a subject, comprising:
- making an opening hole in the body of the calcaneus, talus and tibia;
- inserting an arthrodesis nail in the plantar portion of the heel from the calcaneus into the talus and tibia, the nail comprising a rigid round tibio-talo-calcaneal rod having a bend in the distal portion, wherein the bend is configured to match an anatomic alignment of a hindfoot of the subject, and the rod further comprising proximal and distal holes for locking screws;
- and
- locking the nail in the calcaneus bone with posterior to anterior locking screws to aid in arthrodesis.

A surgical implant kit comprising:
- an arthrodesis nail comprising a rigid round tibio-talo-calcaneal rod having a bend in the distal portion, wherein the bend is configured to match an anatomic alignment of a hindfoot, the rod further comprising proximal and distal holes for locking screws;
- and
- posterior to anterior locking screws;
- and
- a precontoured guidewire to match the bend of the nail to provide a guide for reaming the opening for the insertion of the nail,
- wherein the nail and the screws are configured to lock together to create a compression across ankle joints to aid in arthrodesis, wherein the rod has a bend in the proximal portion, wherein the bend in the proximal portion and the bend in the distal portion create an offset between the ends of the nail.
