Study Notes

Joint Articulations

Trochlea of humerus articulates with trochlear fossa of ulna at the humeroulnar joint.
Humeroradial joint involves the capitulum of humerus with the head of radius.
Proximal radioulnar joint includes the head of radius articulating with radial notch of ulna.

Nerve Injuries

Grade 1 nerve injury features localized conduction block and temporary loss of sensation/motor function, typically resolving in days to weeks.
Grade 2 nerve injury leads to significant motor deficits and mild sensory deficits, with recovery often occurring within several weeks.

Fracture Types

Greenstick fracture is an incomplete break in a bone, akin to how a young twig breaks.
A simple fracture is a type that does not break through the skin, opposite to a compound fracture that does.
An oblique fracture occurs at an angle across the bone.
An impacted fracture results from a bone driven into another bone piece.
Epiphyseal fractures occur along the growth plate, affecting the physes of the bone.
A comminuted fracture results in the bone breaking into multiple pieces.
An avulsion fracture arises when a bone is pulled away by an attached tendon or ligament.
A countercoup fracture typically manifests on the opposite side of the impact.
A longitudinal fracture runs along the length of the long axis of the bone.

Fractures and Injuries Overview

An impacted fracture is characterized by bone pieces being driven into one another.
A spiral fracture usually occurs when twisting forces are applied, leading to a helical break.
Motor and sensory deficits lasting for months may indicate a grade 3 nerve injury, which may require surgical intervention.
The capitulum of the humerus articulates with the head of the radius at the humeroradial joint.
A compound fracture is distinguished by breaking through the skin.
Oblique fractures are distinguished by their angled break, setting them apart from transverse or linear fractures.
