Landmarks for rotational alignment of the humeral component …
Oct 3, 2012 · Our purpose was to assess whether the flat posterior humeral cortex proximal to the olecranon fossa is a reliable landmark with which to orient the humeral component during elbow arthroplasty. Methods: Fifty cadaveric elbows (mean age [and standard deviation] at the time of death, 73 ± 12 years) underwent computed tomography (CT) scans.
Landmarks for Rotational Alignment of the Humeral Component... : JBJS - LWW
Oct 3, 2012 · The reference points for rotational orientation of the humeral component during elbow arthroplasty typically are on the articular surface or the humeral epicondyles. With bone loss, these landmarks may be compromised.
Landmarks for rotational alignment of the humeral component …
The posterior humeral cortex is a reproducible landmark that is externally rotated with respect to the flexion-extension axis of the distal part of the humerus and the surgeon must be aware of the need for an internal rotation correction factor. BACKGROUND The reference points for rotational orientation of the humeral component during elbow arthroplasty typically are …

A Soft-Tissue Landmark to Assess Humeral Component Rotation …
Jul 11, 2023 · The purpose of this study is to test the hypothesis that the intermuscular septum axis (IMSA) is a reliable soft-tissue landmark to set rotation of the humeral component intra-operatively when bony landmarks are not present or are not reliable due to deformity.
Landmarks for Rotational Alignment of the Humeral Component …
Oct 3, 2012 · Navigated alignment was based on positioning the humeral component with the aid of a computed tomography (CT)-based preoperative plan registered to landmarks on the distal humerus.
Primary elbow arthroplasty: problems and solutions - PMC
In a cadaveric study, Sabo et al. 31 showed that the flexion–extension axis is internally rotated by approximately 15° (12° in males and 16° in females) in reference to the posterior cortex of the humerus, and approximately 3° in reference to the transepicondylar axis. Thus, the humeral component should be implanted in approximately 3 ...

The reference points for rotational orientation of the humeral component during elbow arthroplasty typically are on the articular surface or the humeral epicondyles.
A Soft-Tissue Landmark to Assess Humeral Component Rotation …
Jul 11, 2023 · Hypothesis: Assessing the rotational alignment of the humeral component during total elbow arthroplasty is dependent upon bony landmarks that can be absent or altered in cases of distal humerus fractures, revision arthroplasty, severe bone loss, or deformity.
Current concepts in distal humeral hemiarthroplasty - PMC
May 27, 2021 · The humeral stem should be positioned in the epicondylar axis of the native distal humerus for correct rotation (Fig. 6). In a fracture, the bony landmarks that determine this axis are lost, hence a secondary landmark is the flat area of the posterior humerus, proximal to the olecranon fossa.
