What is the depression on the distal end of the anterior humerus?
What is the depression on the distal end of the anterior humerus?
Coronoid Fossa
Which is a spool shaped process on distal end of the humerus that is found medial to the capitulum and articulates with the ulna?
humerus. … smooth articular surfaces (capitulum and trochlea), two depressions (fossae) that form part of the elbow joint, and two projections (epicondyles). The capitulum laterally articulates with the radius; the trochlea, a spool-shaped surface, articulates with the ulna.
Is the radius distal to the humerus?
Humerus: The humerus attaches proximally to the scapula (shoulderblade) at the humeral head and distally with the radius and ulna (lower-arm bones) at the trochlea and capitulum, respectively. The proximal portion of the humerus can be divided into three parts.

What is the most common site for proximal humerus fracture?
The most frequently fractured site of the humerus especially in elderly is the surgical neck which is an area of constriction distal to the tuberosities.
What part of the humerus is the most commonly fractured?
The most common location of proximal fractures is at the surgical neck of the humerus. Incidence of proximal fractures increases with age, with about 75% of cases occurring among people over the age of 60.
How do you prevent a proximal humerus fracture?
For valgus-impacted fractures, a periosteal elevator can be inserted across the fracture and used to lever the fracture out of valgus. Alternatively, direct pressure on the superior aspect of the lateral humeral head subchondral bone can be used to reduce the fracture out of valgus.
How long is ORIF surgery?
ORIF is a two-part procedure. The surgery can take several hours, depending on the fracture. An anesthesiologist will give you general anesthesia. This will put you in a deep sleep during the surgery so you won’t feel any pain.
