In Germany, Halsted had seen Volkmann remove not just the breast, but a thin, fanlike muscle spread out immediately under the breast called the pectoralis minor, in the hopes of cleaning out the minor fragments of leftover cancer.
A great, fan-shaped muscle, called the pectoralis major, lies on the chest.
It can recur on the chest wall, which is called the pectoralis muscle.
Instead of stripping away the thin pectoralis minor, which had little function, Halsted decided to dig even deeper into the breast cavity, cutting through the pectoralis major, the large, prominent muscle responsible for moving the shoulder and the hand.
With the pectoralis major cut off, the shoulders caved inward as if in a perpetual shrug, making it impossible to move the arm forward or sideways.
But Halsted, evidently scornful of “mistaken kindness,” did not stop his surgery at the pectoralis major.
Birds found here and in only few other places include white-bellied seedeaters Sporophila leucoptera, grassland yellow-finches Sicalis luteola, chalk-browed mockingbirds Mimus saturninus, tropical peewees Contopus cinereus, rufous-throated antbirds Gymnopithys rufigula, black-breasted puffbirds Notharchus pectoralis, and plain-bellied emeralds Amazilia leucogaster.
