Question

An adult is swinging a small child by the arms, and the child screams and grabs his left arm. It is determined in the emergency department that the radial head is partially dislocated. What is this partially dislocated radial head documented as?A) Volkmann's contractureB) SubluxationC) Compartment syndromeD) Sprain

Answer 1

Answer: B) Subluxation

Explanation:

A partial dislocation is referred to as a subluxation. A Volkmann's contracture is a clawlike deformity that results from compartment syndrome or obstructed arterial blood flow to the forearm and hand. Compartment syndrome is a condition in which a structure such as a tendon or nerve is constricted in a confined space and affects nerve innervation, leading to subsequent palsy. A sprain is injury to the ligaments surrounding the joint.
