FINAL EXAM Flashcards
test for intrinsic tightness
(Brunnel Littler Test)
Passively flex PIP joint of finger, initially with MCP in flexion and then with the MCP in extension
If there is more PIP flexion when the MCP is flexed than when it is extended, intrinsic tightness exists
If there is no increase in PIP flexion, this implies a capsular tightness
exercises for intrinsic tightness
Interosei and lumbricals
The PIP and DIP joints are held in flexion as the MCP joints are extended
tightness of oblique reticular ligament
This runs palmar to the axis of rotation of the PIP joint and dorsal to the DIP joint axis
This is like the “distal intrinsics”
The DIP joint is flexed passively first with PIP in flexion and then with PIP in extension
If there is more DIP flexion with PIP flexion than extension, you have contracture of the oblique retinacular ligament
extrinsic flexor tightness - to test
Test for this by looking at the adherence or contracture of extrinsic flexors when you maintain fingers and thumb in full extension and passively extend the wrist – increasing flexor tension will occur and cause the fingers to pull into flexion the further the wrist is extended if there is extrinsic flexor tightness
extrinsic flexor exercise
The DIP, PIP and MCP joints are extended with fingers pulling them back
Wrist is slowly extended until the patient feels a stretch in the anterior forearm
extrinsic extensor tightness
Assessed by keeping all of the digits in full flexion passively and then passively flexing the wrist
If the fingers begin to pull into extension, then this is a positive sign for extrinsic extensor tightness
To test for extrinsic extensor tightness distal to the wrist, all PIP and DIP joints are flexed as the MCP is passively flexed and then you note extensor tension
exercise for extrinsic extensors
DIP, PIP and then MCP are flexed after the wrist is slowly flexed until the patient feels a stretching sensation in the dorsum of the forearm
tendon gliding exercises
median nerve glides
hook
full fist
straight fist
median nerve - 6 positions
finger deformities
swan neck: Hyperextension PIP, flexion DIP
boutinniere: Flexion PIP, hyperextension DIP
mallet finger
inflammation
- first phase of tissue healing
4 Signs of Inflammation:
- Redness
- Swelling
- Heat
- Pain
Acute Inflammation: lasts for about 3-5 days, but can last for 10
Chronic inflammation occurs if the inflammatory phase continues from 4-6 weeks
scar tissue
normal process, Scar tissue is weak and unable to handle normal stresses
Scar tissue becomes problematic when it attaches to adjacent structures and prevents normal movement
This is a contracture → anything that limits joint ROM
Contractures may occur with muscle, tendon, ligament, joint capsule, bursa or skin
colors of wounds
Red: Uninfected, properly healing, definite borders
Yellow: Draining, purulent, slough that is semi-liquid to liquid, Contains pus
Black: Covered with necrotic tissue, debridement is needed to prevent infection
cellular events in healing
Phase 1 is the Inflammatory/Edudative or Oozing Stage
Phase 2 is Fibroplasia or Collagen Deposition
Phase 3 is Maturation → Remodeling
pelvic tilts
Posterior pelvic tilt = hip flexion
Anterior pelvic tilt = hip extension
Pelvis moves medially when the hip is abducted and laterally when it is adducted
angle of inclination (hip)
femur-pelvis
125 degrees
increase in angle of inclination
coxa valga, anteversion, CAM impingement
decrease in angle of inclination
coxa vara, retroversion, pincer impingement
angle of torsion
about 8-30, or 15 degrees on average
roles of knee ligaments
Overall, knee ligaments control: Excessive knee flexion, Varus and valgus stresses at the knee, Anterior or posterior displacement of the tibia beneath the femur, rotary stability
degrees of freedom of LE
Hip: 3 Knee: 6 Talocrural (Ankle): 1 Talocalcaneal/Subtalar: 1 Tarsometatarsal: 1 Metatarsophalangeal: 2 Interphalangeal: 1
tibiofemoral alignment
The femur and tibia intersect to create a valgus angle at the knee joint of about 185-190 degrees
genu valgum
occurs when there is an angle of 165 degrees or less that increases compressive forces on the lateral condyle producing “knock knee”
genu varum
occurs when the angle is 180 degrees or more and increases compressive forces on the medial condyle making the person bow legged
patellofemoral joint
tilts medially until about 11 degrees as the knee flexes from 25-130 degrees
ankle joint
Neutral position is at 90 degrees
Dorsiflexion is about 20
Plantar flexion is 30-50
