Study Notes

Here are the study notes based on the provided text:

Knee Joint Examination

Knee flexion: 125-135 degrees
Knee extension: 0-10 degrees hyperextension
Rotation: 10-15 degrees internal and external tibial rotation
Reflexes: Patellar (L4) - hypoactive/absent indicates L4 radiculopathy; hyperactive indicates UMN injury

Knee Joint Provocative Tests

Bulge sign (for minor effusions): apply pressure on the suprapatellar recess to displace fluid downward
Anterior drawer test: pull the tibia forward; positive test if tibia displaces forward
Posterior drawer sign: push the tibia posteriorly; excessive movement suggests an insufficient or torn PCL
Lachman's test: most sensitive exam test for ACL tears
Abduction (or Valgus) stress test: apply a valgus stress to the medial side of the knee; excessive widening indicates a torn MCL

Special Techniques

McMurray Test: for meniscal injury; palpate for clicks or tenderness along the joint line during flexion and extension
Balloon test: for major effusions; palpate for fluid ejected or "ballooning" into the spaces next to the patella

Neurovascular Examination

Motor: knee flexion (sciatic nerve), knee extension (femoral nerve), foot plantarflexion (tibial nerve), foot dorsiflexion (deep peroneal nerve)
Sensory: medial thigh (obturator nerve), anterior thigh (femoral nerve), posterolateral leg (sciatic nerve), dorsal foot (peroneal nerve), plantar foot (tibial nerve)
Pulses: popliteal, dorsalis pedis, posterior tibial

Shoulder Joint Examination

Range of motion: flexion (anterior deltoid, pec major, coracobrachialis, bicep brachii), extension (lat dorsi, teres major, posterior deltoid, tricep brachii), abduction (supraspinatus, middle deltoid, serratus anterior), adduction (pec major, coracobrachialis, lat dorsi, teres major, subscapularis), internal rotation (subscapularis, anterior deltoid, pec major, teres major, latissimus dorsi), external rotation (infraspinatus, teres minor, posterior deltoid, supraspinatus)
Special maneuvers:
- Acromioclavicular joint: Apley scratch test
- Rotator cuff (pain provocation tests): painful arc test, Neer impingement sign

Wrist Joint Examination

Bones: distal radius and ulna, 8 carpal bones
Joint capsule: radiocarpal (wrist) joint, distal radioulnar joint, intercarpal joints
Ligaments: radiocarpal ligament, intercarpal ligaments
