|
What is a dislocation?
|
A disruption of a joint in which the bone ends are no longer in contact.

|
|
What is a subluxation?
|
A partial dislocation.
|
|
|
What is a sprain?
|
A joint injury that involves both dislocation (often partial and/or temporary) and stretching and/or tearing of the ligaments.
|
|
|
What is a strain?
|
A muscle injury involving the stretching or tearing of the muscle.
|
|
|
What is the zone of injury?
|
The area of potentially damaged soft tissue, nerves, and blood vessels surrounding an injury to a bone or joint.
|
|
|
What is a nondisplaced fracture?
|
A hairline fracture. No displacement of bone. May be difficult to distinguish from a sprain or contusion.
|
|
|
What is a displaced fracture?
|
A fracture in which there is obvious deformity or displacement of the bone
|
|
|
What is the most reliable indicator of an underlying fracture?
|
Point tenderness upon palpation.
|
|
|
What is ecchymosis?
|
Bruising.
|
|
|
What is false motion?
|
Motion at a point in a limb where there is no joint. This is a positive indication of a fracture.
|
|
|
What are the most common locations of sprains?
|
Knee and ankle are most common though sprains can occur at any joint.
|
|
|
What is compartment syndrome?
|
An elevation of pressure within the fascial compartment. Frequently seen in fractures below the elbow or knee in children.
|
|
|
What does DCAP-BTLS stand for?
|
Deformities, Contusions, Abrasions, Puncture wounds, Burns, Tenderness, Lacerations, and Swelling.
|
|
|
Generally, what are the boundaries of the zone of injury for a musculoskeletal injury?
|
From the joint above to the joint below, front and back.
|
|
|
How frequently must neurovascular function (CMS) be assessed?
|
Immediately prior to and after splinting and every 5-10 minutes after that until the patient is delivered to the hospital.
|
|
|
What is the primary goal when providing care for muskuloskeletal injuries?
|
Stabilization of the injured limb/joint in the most comfortable position that allows for maintenance of good circulation distal to the injury.
|
|
|
What is the first step in treating an open fracture?
|
Cover the open wound with a clean sterile dressing and apply pressure to control bleeding.
|
|
|
What is the retroperitoneal space?
|
The space between the abdominal cavity and the posterior abdominal wall.
|
|
|
True or false - most hip dislocations are posterior?
|
True.
|
|
|
What are indications of posterior hip dislocation?
|
Patient hold knee to chest with the thigh rotated towards the midline of the body.
|
|
|
What is the most common type of dislocation of the shoulder?
|
Anterior. Caused by forced abduction with external rotation.
|
|
|
What is a common complication associated with posterior hip dislocation?
|
Injury to the sciatic nerve.
|
|
|
True or False - You should splint all suspected knee ligament injuries
|
True.
|
|
|
What is a common complication associated with knee dislocations?
|
Compression or laceration of the popliteal artery.
|
|
|
With a knee injury, what should you do if there is no pulse distal to the injury?
|
Call medical control immediately.
|
|
|
True or False - if a patient has fallen from a height and complains of heel pain, you should use a long backboard to stabilize any possible spinal injury in addition to splinting the foot?
|
True.
|
|
|
What is the acromioclavicular (A/C) joint
|
A simple joint where the scapula and clavicle meet at the top of the shoulder.
|
|
|
What is the calcaneus bone?
|
The heel bone.

|
|
What is the fibula?
|
The outer and smaller of the two lower lag bones.
|
|
|
What is the glenoid fosa?
|
The part of the scapula that joins with the humoral head to form the glenohumoral joint.
|
|
|
What is hematuria?
|
Blood in the urine.
|
|
|
What is a ligament?
|
A band of fibrous tissue that connects bone to bone and strengthens and supports a joint.
|
|
|
What is the position of function?
|
A hand position in which the wrist is slightly dorsiflexed and the fingers are moderately flexed. Used when when splinting injuries to the arm.
|
|
|
What is the pubic synthesis?
|
