The upper trunk (or superior trunk) is a trunk of the brachial plexus which derives from the C5 and C6 roots.

Damage to the upper trunk causes: Arm hangs by side, Elbow cannot flex, Arm medially rotated, Forearm pronated, ‘waiter’s tip’, Loss of sensation over deltoid (C5) and lateral upper limb (C6).

The suprascapular nerve (C5,C6) arises from the upper trunk of the brachial plexus beneath the fascial floor of the posterior triangle, before it passes beneath the transverse scapular ligament and round the lateral border of the scapular spine.

The musculocutaneous and median nerves derive largely from this trunk.

Effectiveness of powered hospital bed movers for reducing physiological strain and back muscle activation.

Daniell N1, Merrett S1, Paul G2.
Applied ergonomics.Appl Ergon.2014 Jul;45(4):849-56. doi: 10.1016/j.apergo.2013.11.001. Epub 2013 Nov 15.
Battery powered bed movers are becoming increasingly common within the hospital setting. The use of powered bed movers is believed to result in reduced physical efforts required by health care workers, which may be associated with a decreased risk of occupation related injuries. However, little work

Segment estimates of mass, center of mass and moment of inertia are required input parameters to analyze the forces and moments acting across the joints. The objectives of this study were to propose a new geometric model for limb segments, to evaluate it against criterion values obtained from DXA, a

Angiomatoid "malignant fibrous histiocytoma" (AMFH) is a tumor of intermediate malignancy and undefined lineage, mostly arising in the extremities of young patients. Examples with a prominent myxoid matrix are very uncommon. Twenty-one cases of myxoid AMFH (among a total of 414) identified in consul
