quiz 3 Flashcards
explain the difference between extra and intra-articular fracture?
Extra-articular: occurs outside joint (bone shaft) and not too big of a deal unless it is a complete fracture
intra-articular: occurs within the joint space and can affect ROM
Explain a boxer fracture
Cause: hitting something very hard with closed fist
Involves proximal end of the 5th metacarpal into the palm
Results from a blow on the distal - dorsal aspect of the closed fist
After a splint comes off, there is a loss in ROM in the MCP jt.
Type of fracture? → impacted, comminuted, simple fracture line
Explain a scaphoid fracture
If it is tender it may = a fracture
Palpation in the snuff box area to the wrist distal to the radial styloid.
MOST COMMON carpal fracture
Damage is usually due to hyperextension of the thumb.
Common cause is falling on outstretched hand. (FOOSH)
Requires open reduction. A hereberts screw is commonly used.
If left untreated, patient may develop avascular necrosis.
what is a colles fracture?
it is a fracture of the distal radius which results in a dinner fork deformity and can happen when falling on an outstretched hand (FOOSH)
what is a torn ulnar collateral ligament of the MCP joint of the thumb?
There can be a grade 1, 2, or 3 sprain
Happens when extreme radial deviation/adduction of the thumb occurs.
Lateral stress it applied to stress patency.
what is a mallet finger?
Avulsion injury
Flexion posture or “droop” of finger at the DIP joint
Complete passive but incomplete active extension of the DIP joint
Cause by a blow to the tip of an extended finger
To repair- splinting in DIP hyperextension for 6 weeks.
what is the boutonniere deformity?
Flexion of PIP jt. & hyperextension of the DIP jt.
Openly reduced→ dorsal hood will be changed forever.
what is a swan neck deformity?
Hyperextension of PIP joint & flexion of DIP joint
Volar and the dorsal hood will be changed forever
what is a closed reduction?
it is less invasive and does not require opening of soft tissues, splits and casts are forms of this
what is an open reduction?
it is more invasive and requires the opening of soft tissues and is usually used in cases where there are more severe fractures that need wires, pins, screws and/or plates
what is a complete fracture?
bone breaks cleanly and does not break the skin
what is a compound/open fracture?
bone ends penetrate through soft tissues and the skin
what is a greenstick fracture
a fracture where the bone breaks incompletely, and occurs more frequently in the younger population because their bones are not ossified yet so it doesn’t break it bends
what is a transverse fracture?
when the bone breaks in a straight line across the bone
what is an oblique fracture?
when a break occurs diagonally when torsion occurs on one end when is being fixed
what is a spiral fracture?
jagged bone end are S-shaped because excessive torsion is applied to a fixed bone, commonly caused by twisting of the bone and heals incorrectly if not fixed (will have to be rebroken if this happens) more common in the finger
what is an avulsion?
Bone fragment is pulled off by an attached tendon or ligament (tendon tears but takes the bone with it)
Caused by injury/fall
Example of avulsion→ mallet finger, dorsal hood tears off distal pharynx.
what is a comminuted fracture?
Bone fragments into several pieces
example → distal radial fractures
Open reduction needed to fix
what is an epiphyseal fracture?
“Growth plate” break
Separation involves the epiphysis of the bone
Identified by X-Ray and need a specialized surgeon to perform surgery.
This type of break prohibits and stunts growth
what is an impacted fracture?
another bone is driven into another piece of bone
what is a depressed fracture?
Occurs on flat bones when the broken bone portion is driven inward
Diffuse axonal and focal axonal
Causes→ blunt trauma
Baseball bat
Hard fall
what is a synonym for healing?
union
what are influences of healing?
age and presence of disease
what nerve wraps around the humerus?
radial nerve
what are 3 phases approach to therapy program based on healing?
stabilize
what is an adhesion?
when two tissues stick together that are not usually stuck together
what is the etiology of thoracic outlet syndrome (TOS)?
A. Tight pectoralis minor. Collar bone and deeper first rib (shoulder girdle) movement can affect the amount of space.
B. Congenital first rib anomaly (not normal from birth) can cause this problem. It takes away the space from the brachial plexus, subclavian vein, and subclavian artery. This is the only one that can be taken care of through surgery.
2B. Dynamic posture related, depending on posture depends how much space those structures have. Narrowing and opening of the space.
C. Tight scalene muscle or overdeveloped scalene muscle.
what is the pathology of thoracic outlet syndrome (TOS)?
compression of the brachial plexus (subclavian vein/artery)
what is RSD or reflex sympathetic dystrophy aka complex regional pain syndrome
it is a secondary complication due to trauma with a skeletal fracture and the sympathetic nervous system is inactive, worsening symptoms
what is phase one of RSD?
phase one is early: hot or cold skin, skin is blotchy, edema (ballooning/soft and pitted edema), aching/burning pain, hypersensitivity, skin is shiny
