tibial n.

How is strength tested and what does each score indicate?
Strength Testing is scored out of 5:
- 0/5: No muscle movement
- 1/5: Visible muscle movment, but no movement at joint
- 2/5: Movement at joint, but not against gravity
- 3/5: Movement against gravity, but not added resistance
- 4/5: Movement against resistance, but less than usual
- 5/5: NORMAL strength
How are nerve reflexes tested and what does each score indicate?
- 0 = absent
- 1+ = hypoactive
- 2+ = normal
- 3+ = hyperactive, no clonus
- 4+ = hyperactive, with clonus
Define gait and what is considered the normal horizantal length and what is considered the normal step length?
- Gait
- Watching a patient walk
- Normal horizontal distance between feet: 4 inches
- Normal step length: 15 inches
- Watching a patient walk
What are the different types of imaging used (5 types) and what are they each used for?
-
Radiograph – used mainly for simple bone and joint imaging
- IMPORTANT: If joint is weight bearing order weight bearing x-rays
- order x-rays for joints above and below if visualizing long bone
- obtain perpendicular images
-
CT – great for bone visualization
- ALWAYS order CT before MRI
- MRI – great for soft tissue, spine, and joints
- Ultrasound – good for real time assessment of dynamic movement
- Bone Scans – not used, can see deformities of the bone
- What type of orthopedic pathology is tendinopathy considered to be?
- Define some symptoms of tendinopathy.
- What are the two types of tendinopathy and what is each characterized by?
- What is the histology of a normal tendon vs an abnromal tendon?
- Type of Pathology: Overuse injury
- Tendinopathy – pain, swelling, impaired performance
- Tendinitis – inflammation
- Tendinosis – degradation
- Normal Tendon: tightly packed collagen fibers, few cells, little vascularization
- Abnormal Tendon: spread out collagen fibers, many cells, more vascularization
- What type of orthopedic pathology do shin splints fall under?
- What is the medical term for shin splints?
- What are they characterized by?
- Pathology: overuse injury
- Medial Tibia Stress Syndrome: Shin Splints
- Periostitis caused by abnormal traction of deep flexor/soleus muscles with tibia
- Generalized pain along the anterior tibia
- Happens when there is sudden increase in exercise
- What type of orthopedic pathology do stress fractures fall under?
- What are they characterized by?
- Treatment?
- Patholgy: overuse injury
- Stress Fractures
- Focalized pain in a specific area of the body
- Low risk vs. high risk based on where it happens
- High risk: if risk of dealyed union or propensity for re-fracture
- Treatment: Non-operative (4-8 weeks) and Operative
What 5 tests are used to evaluate basic tendon and nerve function in the hand?
- Make fist
- Abduct and adduct fingers
- Make okay sign
- Cross fingers
- Abduct thumb

What is the pathogenesis of trigger finger?
- Pathologic process: locking of flexor tendons due to size mismatch between the tendon and pulley/tunnel/sheath
What are the three types of trigger finger and what are they associated with?
- Types
- Primary: idiopathic
- Secondary: associated with systemic disease (i.e. diabetes and rheumatoid arthritis)
- Infantile: early after birth
For trigger finger, what are the treatments for children and what are the treatment for adults?
- Treatments
- Children: observation
- Adults: steroid injections to reduce inflammation or surgical intervention
Define De Quervains tenosynovitis:
- De Quervains tenosynovitis: tendonitis of thumb extensor as they pass through the thenar snuffbox
What structures are involved in De Quevains tenosynovitis? Remember the pneumonic!
Pneumonic: SEX LAP of the 1st Dorsal Compartment
SEX: EXtensor Pollicis Brevis (S=short)
LAP: Abductor Pollicis Longus
What is the treatment for De Quervains tenosynovitis?
- Treatment:
- Non-operative
- Brace
- NSAIDS
- Injection
- Operative
- Release of tunnel
- Non-operative
Where does carpal tunnel occur? What are the motor and sensory changes in carpal tunnel?
Carpal Tunnel Syndrome: affects median nerve at wrist
- Motor changes
- Weakness
- Thenar muscle wasting
- Sensory changes
- Dropping objects due to inability to feel
- Numbness
- Tingling of thumb, index, and middle finger
Where does cubital tunnel occur? What are the motor and sensory changes in cubital tunnel?
Cubital Tunnel Syndrome: affects ulnar nerve at elbow
- Motor changes
- Atrophy of first dorsal interosseous muscle (between thumb and index finger)
- Clawing of ring and pinky finger
- Sensory changes
- Numbness and tingling of pinky and medial half of ring finger
What are two physical examination tests to diagnose carpal tunnel syndrome?
- Tinel Sign at wrist
- Produces electric shock
- Phalen’s Test but doesn’t isolate the median nerve from radial nerve
What are two physical exam findings with cubital tunnel syndrome?
- Elbow flexion with Tinel
- Elbow compression-flexion with Tinel
What are the 4 most common causes of decreased shoulder motion? Describe them in terms of passive/active motion.
Passive motion = active motion → physical barrier to motion
- Arthritis
- Adhesive capsulitis (frozen shoulder): scar tissue forms after stiffening of joint
- Locked dislocation
Passive motion > active motion → no physical barrier to motion
- Pain/weakness
What are the three phases of adhesive capulitis (frozen shoulder)? How does the pain and ROM progress in each phase? How long does each phase last?
Freezing
- Progressive increase in pain
- Worsening range of motion
- Lasts 6 weeks to 9 months
Frozen
- Pain goes away but unable to move shoulder
- Lasts 4 to 6 months
Thawing
- Range of motion returns slowly
- Lasts 6 months to 2 years
What are the 4 muscles of the rotator cuff and what are their functions?
- Supraspinatus: ABduct 0-15
- Infraspinatus: Externally rotate with arm at SIDE
- Teres minor: Externally rotate with arm abducted
- Subscapularis: Medially/internally rotate
