The osteo-anconeus flap. An approach for total elbow arthroplasty

Hospital for Special Surgery, New York, N.Y. 10021.
Twenty-seven consecutive primary total elbow arthroplasties were done with
a technique that preserved the continuity of the attachment of the triceps
brachii muscle with a wafer of bone from the reflected extra-articular
portion of the olecranon and with the lateral fascia of muscles of the
forearm. During closure, the wafer was reattached to the broad cancellous
surface of the olecranon with sutures through the bone. The elbows were
immobilized for an average of sixteen days postoperatively. The patients
who were available for follow-up were re-examined at an average of 3.9
years, and the strength of the triceps muscle was checked. No extensor lag
or avulsion of the triceps occurred, and mild extensor weakness was seen in
only two elbows. No patient had early or late drainage of the wound or
infection. The average range of motion compared favorably with that in
other reported series. This osteo-anconeus posterior approach is advocated
for total elbow arthroplasty because it provides rapid and wide exposure,
it is associated with a low rate of complications related to the wound, and
it preserves the strength of the triceps.
