Q

Bicipital Tendonitis

A

“nonarticular disorders”

  • anterior shoulder pain (diffuse) from irritation of the long head of the bicepts tendon
  • palpation of bicipital tendon elicits pain but compare slides
    - Yergason’s sign, speed’s test
  • prolonged cases with full tendon rupture can occur producing “Popeye’s sign”

Q

Partial Rotator Cuff Tear

A

weakness, pain, loss of abduction

27
Q

Cervical Radiculopathy

A
  • manifest with shoulder pain, the area of referred pain has dermatomal pattern consistent with the distribution of dermatomal nerve roots
  • pain can be differentiated from shoulder pain by: history, physical, EMG, cervical radiographs, myelography or MRI
28
Q

Brachial Neuritis

A

-painful condition of shoulder associated with limitation of motion after which pain subsides leaving weakness of shoulder muscles including deltoid, supraspinatus, infraspinatis, biceps and triceps and can also have an associated paralysis of the diaphragm; cause is unclear but thought to be associated with viral or post viral syndromes and has developed after a previous vaccination.

29
Q

Nerve Entrapment Syndromes

A

-referred pain to the shoulder; distant compression neuropathies such as carpal tunnel (median nerve) and cubital tunnel (ulnar nerve) may manifest with concomitant and separate shoulder impingement with rotator cuff disease; associated numbness and paresthesias with mapping of the dermatomal distribution and with peripheral neuropathy often direct the examiner to the appropriate diagnosis; in quadrilateral space syndrome, the axillary nerve is compressed and typically occurs when the arm is held in abduction and external rotation with subsequent tightening of fibrous bands across the nerve and is most commonly seen in the dominant shoulder of young athletic individuals such as pitchers, swimmers and tennis players who function with excessive overhead activity; suprascapular nerve entrapment syndrome can be caused by a traction lesion resulting from repetitive overhead activities, a compression lesion, or both to the nerve, caused by tethering of the nerve at the suprascapular notch by the suprascapular ligament, or the spinoglenoid notch by the transverse ligament.

30
Q

Reflex Sympathetic Dystrophy (RSD) [New Name=COMPLEX REGIONAL PAIN SYNDROME]

A

poorly understood and frequently overlooked condition (also known as causalgia, shoulder-hand syndrome and Sudeck’s atrophy) that is generally associated with minor trauma and is to be differentiated from causalgia which involves trauma to major nerve roots; RSD has 3 phases: Phase 1 is characterized by sympathetic overflow with diffuse swelling, pain, increased vascularity and radiographic evidence of demineralization. Phase 2 is characterized by atrophy and the extremity may be cold and shiny with atrophy of skin and muscles. Phase 3 refers to progression of trophic changes with irreversible flexion contractures, a pale, cold and painful extremity.

31
Q

Neoplasms

A

primary or metastatic may cause shoulder pain by direct invasion of musculoskeletal system or by compression with referred pain; In younger individuals consider chondroblastoma (proximal humeral epiphysis) osteogenic sarcoma (metaphysics); For older individuals consider metastatic lesions and myeloma; pancoast syndrome or apical lung tumor may manifest as shoulder or cervical radiculitis.

32
Q

Dialysis Shoulder Arthropathy

A

is seen in some long-term hemodialysis patients and consists of shoulder pain, weakness, loss of motion, and functional limitation. Cause is unknown but may improve with correction of underlying metabolic disorder such as osteomalacia and secondary hyperparathyroidism.

33
Q

Osteonecrosis

A

to necrosis of the humeral head seen in association with a variety of conditions with symptoms due to synovitis and joint incongruity resulting from resorption, repair and remodeling; most common cause is avascularity resulting from a fracture through the anatomic neck of the humerus secondary to condition such as long-term steroid use, SLE, hemaglobinopathies, pancreatitis and hyperbarism.

34

A

rest, shoe modification, a heel raise to reduce tendon stretching, NSAIDs, physiotherapy and splinting if needed

50
Q

Achilles bursitis

A

is associated with posterior heel pain made worse by passive dorsiflexion of the ankle; bursal distention produces a tendon swelling behind the ankle with bulging on both sides of the tendon; may occur with Achilles tendinitis; treatment is similar as for Achilles tendinitis.

51
Q

Plantar fasciitis

A

most common cause of heel pain and results from repetitive microtrauma causing tearing and stretching of the fibers of the plantar fascia and its narrow proximal calcaneal attachment

  • Localized tenderness, without swelling is present over the anteromedial portion of the plantar surface of the calcaneus
  • Passive dorsiflexion of the toes often accentuates the discomfort
  • Commonly seen in obese middle-aged and elderly patients as a result of repetitive trauma from athletic activities
  • worse in morning
52
Q

Flat feet (pes planus)

  • hereditary
  • watch for rupture of posterior tibialis tendon
  • calcaneus is everted and out-toeing is seen on ambulation
53
Q

Cavus feet (pes cavus

A

unusually high arch and is usually hereditary but can follow poliomyelitis, Friedreich’s ataxia or spina bifida; it is usually asymptomatic but can cause foot fatigue and discomfort particularly in runners; shoe modification to accommodate the high instep and claw toes, metatarsal pads with cushioned high arch supports and stretching exercises of the toe extensors are usually helpful

54
Q

Metatarsalgia

A

is pain and tenderness in and about the metatarsal heads or MTP joints and may be limited to a single joint or generalized across the ball of the foot; pain in the forefoot on standing and walking and tenderness on palpation of the metatarsal heads and sometimes in MTP joints are the main clinical findings; this condition frequently follows years of disuse and weakness of the intrinsic muscles due to chronic foot strain from improper footwear with the toes cramped into tight or pointed shoes, but can be associated with a variety of other foot conditions

55
Q

Sesamoiditis

A

results from damage to the articular surfaces between the sesamoids and the first metatarsal head resulting in chondromalacia or osteoarthritis; the area becomes painful, inflamed and is referred to as sesamoiditis; treatment consists of shifting the weight elsewhere by means of a soft metatarsal support, rest, activity modification and NSAIDs; in patients with severe disability, sesamoidectomy may be required

56
Q

Treatment of Flat feet (pes planus

If symptomatic, a soft orthotic polyethylene-foam-lined arch support often produces symptomatic relief
