Q

symptoms of cervical radiculopathy

A
  • -> neck pain & radicular pain associated with numbness & paresthesia in the upper extremity in the distribution of involved root.
      • reflexes are typically reduced in radiculopathy of the C5 C6 or C7 nerve roots, but there are no standard reflexes that reflect the distribution of the C8 and T1 nerve roots
  • -> muscle spasm or fasciculations in the involved myotomes may occur
  • -> weakness, lack of coordination, changes in handwriting, grip strength, dropping objects from the hand, pain in radiating into the paraspinal and scapular regions (typical of those with root pressure above C5)
  • ->Pts may report they can relieve the pain by placing the hands on top of their head as this decreases tension on the involved nerve root.

Q

spurling’s maneuver

A

+ if limb pain or paresthesias are produced (the test should then be stopped)

  • production of neck pain alone in response to the Spurling maneuver is nonspecific and constitutes a negative test
  • The Spurling test has high specificity for the presence of cervical radiculopathy , but its sensitivity is low to moderate. A positive Spurling test is helpful for supporting the dx of cervical radiculopathy, but negative test does not rule out radicular pathology

**never perform in patients who may have instability of cervical spine, (rheumatoid arthritis, cervical malformation or metastatic disease, since it may cause further injury to the spine. In addition, it should not be perfomed when associated cervical myelopathy is suspected.

Q

indications of EMG

A

The diagnosis of radiculopathy is usually CONFIRMED by needle electromyography (EMG) which frequently reveals a myotomal pattern of denervation.
nerve conduction studies alone are not sensitive for radiculopathy.
performing electrodiagnostic testing when symptoms have been present for less than 3 weeks reduces the sensitivity of the test

Q

treatment for neck pain & paresthesias (neck radiculopathy)

A

Conservative treatment for pt with cervical radiculopathy who have clear radicular pain and symptoms of paresthesia, numbness, or nonprogressive neurologic deficits
—>Oral analgesics (eg. NSAIDS) avoidance of provocative activities, add short course of oral PREDNISONE if pain is severe
—>once the pain is tolerable, initiate PT with exercise & gradual mobilization.
With confirmed cervical radiculopathy with severe or disabling pain despite a course of conservative therapy, & who do not have a progressively worsening neurologic deficit, recommendation is use of epidural steroid injections rather than surgery

pt. who complain of elbow swelling most often have olecranon bursitis
warmth & redness that accompany the swelling and the rapidity with which the symptoms appear are clues to distinguish the underlying cause (usually trauma, sepsis , or gout)
The ability of the pt to extend and flex the elbow completely generally excludes an intrarticular process as the cause of the elbow pain

52
Q

medial epicondylitis “golfer’s elbow” pain

A

medial elbow pain is the second most common complaint at the elbow. it frequently arise either from the medical epicondyle or the ulner nerve as it travels through the cubital tunnel
as with lateral epicondylitis the pain of medical epicondylitis is well localized and is aggravated by actions that contract the wrist flexors, such as lifting or repetitious use of the forearm and wrist

53
Q

lateral epicondylitis “tennis elbow” pain

A

lateral elbow pain is the most common complaint at the elbow. the source of pain may be the lateral epicondyle, the radiohumeral uoint, or referred pain from the shoulder or neck

the pain of lateral epicondylitis (tennis elbow) is typically well localized (the patient often points to the lateral epicondylar process) and is aggravated by activity that contracts the wrist extensors, including repetitious use of the forearm and wrist and shaking hands.

54
Q

treatment for olecranon bursitis

small mass & mild symptoms:

A
  • -> bursitis should be left alone or tx symptomatically with activity modification and possible NSAIDs
  • ->wear an elbow pad & avoiding hyperflexion against hard surfaces may improve symptoms.
55
Q

treatment for olecranon bursitis

more symptomatic bursitis

A

undergo aspiration of the bursa, followed by gram stain & culture of suspicious fluid
if no indication of septic bursitis a compression bandage consisting of circular foam, 8cm in diameter and an elastic warp should be applied.
reassess pt in 2-7 days

56
Q

treatment for olecranon bursitis:

septic bursitis

58
Q

symptoms of carpal tunnel syndrome

A

reports vague aching that radiates into the thenar area
aching may be perceived in the proximal forearm an pain can extend into the shoulder
pain is typically accompanied by paresthesias or numbness in the median distribution (thumb index finger long finger, or some combination of those )
often symptoms are worse at night
dropping objects can’t open jars or twist lids

59

oral glucocorticoids
carpal bone mobilization and yoga may also be beneficial
Referral to an occupational therapist with subspecialty certification in hand therapy may improve outcomes

62
Q

unresponse to wrist splinting (carpal tunnel syndrome)

A

inject methylprednisone 40mg if declines injection try oral prednison 20mg daily for 10-14 days

surgical decompression - moderate to severe CTS that is refractory to conservative measures

63
Q

Osteoarthritis

A

result from multiple factors include joint integrity, genetics, local inflammation, mechanical forces, and cellular and biochemical processes

common: >40 y.o.
pain is exacerbated by activity and relieved by rest

64
Q

osteoarthritis symptoms

A

stiffness (resolves in the morning less than 30 minutes after awakening; the recurrence of stiffness that may occur with inactivity is termed gelling
tenderness on palpation, typically in the absence of inflammation, crepitus, bony enlargement, decreased range of motion; and malalignment; synovial effusion, if present show mild pleocytosis, normal viscosity, and modestly elevated protein

65
Q

where does OA affect

A

all joints but not equally, it has a predilection for the FINGERS, KNEES, HIPS, SPINE, and rarely the elbows, wrists and ankles
OA is generally slowly progressive, although it stabilizes in some pts. The course of those with progressive disease is usually one of intermittent worsening.

66
Q

Rheumatoid Arthritis

A

chronic systemic inflammatory disorder of unknown etiology that primarily involves joints
symmetrical
progresses from periphery to more proximal joints and pts who do not fully respond to tx result in significant locomotor disability within 10-20 years
