Pathology MEGA DECK Flashcards
Developmental dysplasia of the hip is cause by?
patients who are born with dislocation or instability of the hip, which may then result in hip dysplasia
What are the symptoms of developmental dysplasia of the hip?
most commonly first born female, breech, left hip
LCP (avascular necrosis) disease is caused by?
result of damage to blood supply to femoral head ossific nodules; unknown etiology
LCP: Legg-Calve-Perthes
What is the cause and symptoms of Slipped Capital Femoral Epiphysis?
acute trauma or repetitive microtrauma, kids 10-17y mechanical effect due to obesity, increased shear forces on physis, may result in coxa vara, hip discomfort referred to knee (obturator nerve), externally rotated gait with limp, leg length discrepancy, limited flexion
What is the causes and symptom of Winged scapula?
damage to long thoracic nerve causes paralysis of serratus anterior muscle medial border and inferior angle of scapula pulled away from posterior thoracic wall when arm is raised or pushing against object. Arm cannot abduct above horizontal position.
What is the cause and symptoms of Erb’s Palsy?
excessive separation of head and neck; such as falling with shoulder on ground or excessive stretching during baby delivery waiter’s tip appearance - injured limb hangs by side in medial rotation; loss of sensation on lateral aspect of upper limb, deltoid, biceps, brachialis, and brachioradialis paralysis
What is the cause and symptoms of backpackers palsy?
micro injury of superior trunk of BP due to carrying heavy backpack sensory deficits in distribution of musculocutaneus and radial nerves, muscle spasms
What are the symptoms and cause of Ulnar nerve injury?
direct hit against hard object or fracture of medial epicondyle, tendinous cubital tunnel, wrist, or hand numbness/tingling at medial palm and digits 4-5, clawhand (loss of Z movement), lean to radial side when flexing the wrist
What are the symptoms and cause of Cubital tunnel syndrome?
ulnar nerve is compressed by flexor carpi ulnaris at its proximal attachment same as ulnar nerve injury
What are the symptoms and cause of rupture of the long head of biceps?
wear and tear of an inflamed tendon, forceful flexion of the arm Popeye deformity; detached muscle belly forms a ball near the center of the distal part of the anterior aspect of the arm
What are the symptoms and cause of pronator syndrome?
median nerve in jury due to compression between heads of pronator teres muscle pain and tenderness in proximal anterior forearm
Median nerve injury has what characteristic sign?
Hand of Benediction / Pope’s Hand flexion of 2-3 lost at MCP joint; flexion of digits 1-3 are lost, 4-5 are weakened at PIP joint; flexion of digits 2-3 are lost, 4-5 not affected at DIP joint
What are the symptoms and cause of elbow tendonitis?
caused by repetitive forceful flexion/extension of the wrist, inflammation of the periosteum of the lateral epicondyle where the superficial extensors form a common tendon to attach pain at lateral epicondyle, radiates down posterior forearm, can be felt at rest or when opening a door/lifting a glass
What are the symptoms and cause of mallet/baseball finger?
caused by sudden forceful extension of a long extensor tendon such as a finger jammed into a base pad DIP cannot extend and is pulled in flexion by flexor tendons
What are the characteristics of a synovial cyst of the wrist?
painful, most common on dorsum of the wrist about the size of a small grape, contain clear mucinous fluid, may communicate with synovial sheaths if on palmar hand may cause median nerve compression
What are the symptoms of radial nerve injury?
Arm - wrist drop deep branch - Inability to extend thumb/MCPs Superficial branch - coin shaped area of numbness in dorsal hand
What are the cause and symptoms of Dupuytren’s Contracture of Palmar Fascia?
progressive shortening, thickening and fibrosis of palmar fascia and aponeurosis, hereditary? Usually bilateral, males 50+ 4th/5th fingers are pulled into partial flexion at MCP and PIP, painless nodular thickenings on palmar aponeurosis, develops into contracting longitudinal bands in the palm
What are the cause and symptoms of Tenosynovitis?
infection of the synovial sheath caused by injury to palm swelling/painful digits, infection can spread to palm, carpal tunnel and forearm, if digital synovial sheath ruptures can spread into midpalmar space
What are the cause and symptoms of De Quervains’s Tenovaginitis Stenosans?
excessive friction of APL and EPB causes fibrous thickening of synovial sheath pain in wrist, radiates into forearm and thumb hold thumb inside other four fingers and adduct (ulnar deviate) wrist joint - painful
What are the cause and symptoms of Digital Tenovaginitis Stenosans (Trigger Finger)?
repetitive forceful use of fingers causes thickening of fibrous digital sheath, FDS/FDP may enlarge finger cannot extend, passive extension of finger results in snapping sound
What are the cause and symptoms of AC Joint Dislocation?
direct impact to shoulder or outstretched arm, often called shoulder separation tear of coracoclavicular lig results in downward separation of upper limb from clavicle, acromion is more prominent, fibrous capsule of AC joint also torn
What are the cause and symptoms of Calcific Supraspinatus Tendonitis (Painful Arc Syndrome)?
inflammation and calcification of the supraspinatus tendon, inflammation of subacromial bursa affects people 50+ years, pain in should with 5-130 degrees of abduction
What are the cause and symptoms of Adhesive Capsulitis of Glenohumeral Joint (Frozen Shoulder)?
fibrosis/scarring in articular capsule due to injuries such as calcific supraspinatus tendonitis, partial rotator cuff tear or bicipital tendonitis difficult abducting arm
What are the cause and symptoms of Dislocation of Radial Head (Pulled Elbow)?
sudden lifting of child’s body by pulling arm, head of radius is pulled out of anular ligament, may be torn common in preschool children, immobile arm and protective position (pain)
