Humerus Anatomy
Friday, 27 September 2019 10:00 PM
The humerus is described as having a proximal
region, shaft, and distal region. The humerus
articulates proximal region by the scapula at
the shoulder joint and radius and distal region
with ulna at the elbow joint. Anatomical and
surgical neck both of the humerus are highly
susceptible to fracture.
The humeral upper extremity comprises a
rounded head, a narrow neck, and two short
processes (tubercles/ tuberosities). The body is
cylindrical in its upper section and more prismatic
below. The lower extremity comprises 2
epicondyles, 2 processes (trochlea & capitulum),
and 3 fossae (radial fossa, coronoid fossa, and
olecranon fossa). And it refers to its true
anatomical neck, the constriction below the
greater and lesser tubercles of the humerus to as
its surgical neck for its tendency to fracture, thus
often becoming the focus of surgeons.
