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.
