Approach to the Musculoskeletal Patient Flashcards
(67 cards)
Common musculoskeletal chief complaints include:
- Pain/Stiffness
- Instability/Dysfunction
- Deformity
- Weakness
4 Goals for Evaluating Patients with Musculoskeletal Complaints
- Develop accurate diagnosis
- Provide timely care
- Avoid unnecessary testing
- Identify “red flag” conditions
Keys to Success In Evaluating MSK Complaints
- appropriate, thorough hx
- PE
- DDX - Considering MC disorders first
- Consider need for diagnostic testing
what is often the most important factor in diagnosing musculoskeletal problems
history!
- Obtain a complete ROS
- Thorough past medical history
- Review medications and allergies
- Family history
Key Historical MSK Considerations
LOCATES
- Onset
- Location
- Quality/Character
- Timing/Duration
- Aggravators/relievers
- Associated signs & symptoms
Onset questions when taking hx?
- When?
- Activity at onset?
- Was there an injury?
- What was the MOI? - Timing of onset?
- Sudden vs insidious
location questions when taking hx?
- Joint
- Unilateral vs Bilateral - Bone
- Midshaft
- Joint involvement - Soft tissue
- Muscle, tendon, ligament
Quality/character of pain when taking hx?
- Catching/locking in the joint
- Instability/giving way
- Burning
- Aching vs. sharp
- Radiating
associated s/s of MSK compliant when taking hx?
- Systemic Symptoms
- Neurogenic Symptoms
- Inflammatory Symptoms
MSK/Orthopedic complaints classification
- Traumatic vs. atraumatic
- Articular vs. nonarticular
- Localized/Monoarticular vs. widespread/polyarticular
- Acute vs. chronic
- Inflammatory vs. non-inflammatory
MSK Physical Exam Goals
- Determine structures involved
- Determine the nature of the underlying pathology
- Determine the functional consequences of the process
- Determine the presence of systemic or extraarticular manifestations
Key Physical Exam Principles
- Inspection
- Palpation
- Range of motion
- Neovascular status
- Muscle testing
- Motor and Sensory evaluation
- Special tests
Inspection components of MSK PE
- Expose area of concern
- Have pt point to area of maximal pain/tenderness
- REMEMBER “SEADS” - Swelling, erythema, atrophy, deformity, scars/skin
When examining the extremities, it is IMPERATIVE to examine how?
BILATERALLY
For palpation what are you assessing
- Assess for tenderness, masses, fluctuance, temperature changes, crepitus - Locate point of maximal tenderness
- Imagine the anatomy as you are palpating
- Hard → bone
- Spongy/Boggy → synovial thickening
- Fluctuance → effusion
- Position→ joint or periarticular (bursa)
pain SHOULD NOT discourage you from palpating the affected area
How to assess ROM during MSK exam?
- Provides info on severity and progression of disorder
- Always compare sides!
- Types of ROM:
- Active (AROM)
- Passive (PROM)
- Active Assistive Range of Motion (AAROM) - Measuring ROM
- Can be estimated
- More accurate assessment utilizing a goniometer
Goniometer are preferred for evaluating these specific joints:
- Elbow
- Wrist
- Digits
- Knee
- Ankle
- Great toe
Goniometers are less useful for ___ and ___ ROM evaulation
Hip and shoulder
Overlying soft tissue structures don’t allow for as much precision
how to use a goniometer?
- Start by placing the joint in the “Zero Starting Position”
- In most joints this is in the anatomic position of the extremity in extension - Place the center of the goniometer at the joint
- Have patient actively perform ROM
- Move the distal end of the goniometer to align with the distal extremity
Manual Muscle Testing Grades
- 5/5: Normal (complete ROM against gravity w/full resistance)
- 4/5: Good (complete ROM against gravity w/some resistance) - Sometimes subdivided into 4-, 4, and 4+
- 3/5: Fair (ROM against gravity, but not with resistance)
- 2/5 : Poor (ROM only if gravity eliminated)
- 1/5: Trace (twitch/muscle contraction but no joint motion)
- 0/5: Absent (muscle does not contract)
what is the Neurovascular Assessment
- Assess vascular status in trauma patient
- Assess one muscle/nerve at a time
- Neck and Back - Assess nerve root function
- Extremity - Peripheral nerve testing
- Digits - 2-point discrimination
First line in bone and joint imaging, especially for initial evaluation
Radiography
advantages of Radiography
- fast, inexpensive, readily available, easily interpreted
- Plain x-ray is often needed (by insurance) prior to more detailed imaging
disadvantages of radiography
poor soft tissue contrast, 2D, quality is technician dependent, some radiation exposure (small)
