While deltoid length can be easily measured in a cadaver, we were not able
to find a method for reproducibly measuring the deltoid length in a patient.
In our opinion, measuring deltoid length requires additional techniques.A reference point for a surgical exposure must be easy to locate by
palpation because the surgeon may need to check the reference site again later
in the operation. Because of that need, the upper border of the deltoid muscle
may not be sufficiently discrete to serve as a reference point
intraoperatively, as recommended by Kontakis et
