Pearls |
Care should be taken to subperiosteally expose the olecranon sufficiently to allow protection of the ulnar nerve medially and placement of knots under the anconeus laterally. |
Care should be taken to remove degenerative appearing tissue from the tendon edges. |
A high-speed burr should be used to remove all soft tissue and lightly decorticate the footprint. |
The cruciate drill tunnels should be placed on the most proximal medial and lateral aspects of the footprint to allow complete anatomic coverage of the footprint. |
An Army-Navy retractor should be used to protect the ulnar nerve while drilling the transverse tunnel. |
The arm should be placed in full extension and skeletal relaxation should be used while tying the sutures. |
Pitfalls |
Removing too much bone when preparing the footprint |
Failure to aim the drill away from the joint surface during transosseous tunnel placement |
Failure to protect the ulnar nerve while drilling the transverse drill tunnel |
Not placing the knots under the anconeus to avoid knot irritation |
