AI Technical Summary

Problems solved by technology

However, these techniques create complications
Fixation with tension band wires and K-wires can cause K-wires and wires to protrude under the skin, causing local irritation and requiring secondary surgery for removal
Similarly, plate immobilization can cause the plate to protrude under the skin causing local irritation and requiring removal
Fixation with lag screws is problematic because the curvature of the proximal ulna can make accurate screw placement along the medullary canal difficult
Alternatively, lag screws can be used with tension band wires to solve this problem, but using tension band wires creates the associated problems described above

Embodiment Construction

[0071] The present invention relates to an osteotomy nail insertion system. The osteotomy nailing system includes an osteotomy nailing system 10 and an insertion device 30 . The osteotomy nail system 10 ensures proper anatomical reduction of the osteotomy. The insertion device 30 enables the osteotomy nail system 10 to be firmly fixed within the medullary cavity of the bone. Also, the present invention provides methods for inserting the osteotomy nail system 10 , securing the osteotomy nail system 10 and securing the osteotomy with the insertion device 30 .

[0072] exist Figure 1A In the illustrated embodiment, the osteotomy nail system 10 includes an osteotomy nail 20 , at least two screws 23 and a nail cap 24 . As shown, the osteotomy nail 20 is secured in bone with a screw 23 and a nail cap 24 .

[0073] refer to Figure 2A-2B , according to one embodiment, the osteotomy nail 20 comprises a head 210 and a body portion 220, which are preferably integrally formed into a...

Abstract

The present invention relates to a nail system for fixation of an olecranon osteotomy or fracture. The nail system of the present invention is securely held in place in the intramedullary canal to ensure proper anatomic reduction of an osteotomy. Further, the invention provides an insertion device and a method for inserting the osteotomy nail system, securing the osteotomy nail system, and fixing the osteotomy.

Description

[0001] related application [0001] This application claims the benefit of US Application No. 60 / 799,428, filed May 9, 2006, the contents of which are incorporated herein by reference. technical field [0002] The present invention generally relates to devices for the fixation of condyles. More specifically, the present invention relates to nails for the fixation of olecranon osteotomies or fractures. The invention also relates to devices and methods for securing said staples. Background technique [0003] Distal humerus fractures in adults are optimally treated with open anatomical reduction and stable fixation to achieve early anatomical repair and upper extremity range of motion. Therefore, surgical exposure is often necessary for the treatment of distal humeral fractures. Olecranon osteotomy provides a wide exposure of the distal humerus that is optimal for repairing complex distal humeral fractures. Olecranon osteotomy is a surgical procedure in which a large promin...
