Putting It All Together - Hands Flashcards
What is the condition called when there is an injury at the DIP tendon which results in no active DIP extension and unopposed flexion? The DIP joint remains in flexion and can become contracted.
Mallet finger
This can result as a late effect of mallet finger
Swan Neck Deformity
Occurs when there is increased pressure in a closed space in the limb that can cause ischemia and damage to the contents of the space; decrease occurs in tissue perfusion, oxygenation, and later reduction in function
Compartment syndrome
What are some causes of compartment syndrome?
Trauma, crush injuries, and swelling
All of these symptoms are characteristics of what?
Pain, parasthesias(numbness, tingling), pulselessness or decreased pulse, paleness of skin, paralysis, weak muscles
Compartment syndrome (insert needle into the compartment to test pressure; if surgery is done on time, results can be good)
T/F: Compartment syndrome can be prevented by monitoring edema if a patient is casted and ensuring bandages are not too tight
True
What issue does this describe? Compression occurs in anterior compartment of the forearm, extrinsic flexors of the digits (FDS and FDP) can be affected; without treatment, flexors can shorten and DIP joints can become contracted into flexion
Volkmann’s Ischemic Contracture
Tightness or contracture of lumbricals and interossei
Intrinsic Plus Hand
Low ulnar nerve injury such as laceration at wrist level; small and ring finger in “claw” position of MCP hyperextension and PIP/DIP flexion; leads to impaired grip strength; thumb loses stabilizer for pinch (adductor)
Intrinsic Minus hand
T/F: The instrinsic minus hand can affect all fingers if there is a low ulnar and median nerve injury - in which case all fingers would be extended at MCP joint and flexed at PIP and DIP joints
True
A nodule or thickening that occurs over the A-1 pulley as a result of inflammation of the synovium where the tendons pass through; makes a “snap” noise and in severe cases, the patient has to pull finger up manually
Flexor Tenosynovitis - Trigger Finger and Thumb
T/F: Some conservative treatment methods for trigger finger include full time splinting, ROM exercises to avoid stiffness, anti-inflammatory meds, corticosteroid injection, and activity modification; surgery is also an option if these don’t work
True
What is iontophoresis treatment?
Use of direct current to transport anti-inflammatory medication into region of A-1 pulley; requires prescription and insurance approval or self-pay
Inflammation or thickening in the tendon sheath of the abductor pollicis longus and extensor pollicis brevis
deQuervain’s Tenosynovitis
T/F: Finklesteins test is where the pt puts thumb in palm and digits in fist and patient ulnar deviates the wrist; can be very painful if they have deQuervain’s tenosynovitis
True
