Materials and methods
Thirty-six fresh-frozen cadaveric upper extremity specimens spanning from the disarticulated glenohumeral joint to the hand were obtained from the Department of Anatomy at our institution. None of the specimens had evidence of prior surgery or injury to the elbow. Specimens were excluded if there was evidence of osteoarthritis of the elbow manifested by osteophyte formation at the olecranon tip or fossa. The mean age of the cadavers was 71.3 years (range, 47-89 years). There were 13 male and 10
Results
Interobserver reliability was determined for each of the measured values in 14 specimens. Intraclass correlation coefficients ranged from 0.903 to 0.996, indicating excellent interobserver reliability (Table I).
Discussion
The anatomy of the distal triceps tendon insertion has received little attention in the orthopaedic literature. An accurate understanding of this anatomy is important for posterior elbow approaches where a split or reflection of the triceps mechanism is performed for deep exposure. Strategies to minimize surgical insult or post-repair complications to the triceps insertion must be founded in a better understanding of the normal anatomy.
On the medial aspect of the elbow, the triceps mechanism
