What are the etiologies of bursitis?
cumulative trauma, infection -> inflammation of bursae of synovial joint
What are the clinical features of bursiitis?
S/S:
- tenderness, pain with movement, limited ROM, edema
DIAGNOSTIC TESTS:
- radiography may reveal severity of bursitis and possible calcificaiton
- aspiration can rule out septic arthritis
Whats the treatment and prognosis of bursitis?
TREATMENT:
- NSAIDs, corticosteroid injections, exercises
- surgical excision of any calcifications
PROGNOSIS:
- excellent :DD with treatment
What are the etiologies of osteomyelitis?
(usually) staphylococcal aureus infects proximal humerus or tibia through direct wound or systemic infection -> subperiosteal abscess may form and fragment bone
What are the clinical features of osteomyelitis?
S/S:
- fever, malaise, sweating
- swelling, redness, and pain at site of infection
DIAGNOSTIC TESTS:
- aspiration may reveal pathogen
- radiography may reveal extent of infection
What’s the treatment and prognosis of osteomyelitis?
TREATMENT:
- long-term antibiotics
- possible surgical drainage and/or bone graft
PROGNOSIS:
- curable, but risk of long-term bone deformities
What are the etiologies of gout?
inherited uric acid cycle defects, kidney dysfunction, cytotoxic chemotherapy -> buildup of uric acid in joints
What are the clinical features of gout?
S/S:
- excruciating pain in synovial joints, slight fever, nausea, renal calculi
DIAGNOSTIC TESTS:
- aspiration reveals uric acid crystals
What’s the treatment and prognosis of gout?
TREATMENT:
- NSAIDs, corticosteroids, colchicine
- low-purine diet
PROGNOSIS:
- good with treatmment, risk of bone and joint damage without
What are the clinical featurs of Paget’s disease (or osteitis deformans)?
S/S:
- susceptibility to fractures, local bone pain that’s prominent at night, possible deafness
DIAGNOSTIC TESTS:
- blood tests show elevated alkaline phosphatase
- urinalysis reveals elevated hydroxyproline
What’s the treatment and prognosis of Paget’s disease (or osteitis deformans)?
TREATMENT:
- calcitonin, biphosphinate drugs
- high-vitamin D, high-calcium, high-protein diet
PROGNOSIS:
- generally good, especially if treated early
- slight risk of osteosarcoma
What’s the etiology of Marfan syndrome?
autosomal dominant gene on chromosome 15 -> defect of fibrillin protein
What are the clinical features of Marfan syndrome?
S/S:
- abnormally long extremities, subluxation of lens, hear and vascular anomalies, hyperextensible joints
DIAGNOSTIC TESTS:
- family history, presence of signs/symptoms may indicate syndomre
- echocardiogram may identify aortic abnormalities
What’s the treatment and prognosis of Marfan syndrome?
TREATMENT:
- growth hormone blockers
- possible aortic bypass graft surgery
- possible valve replacement
PROGNOSIS:
- heart and vascular defects carry high risk of complications
What are the etiologies of bone cancers?
- (if primary) growth spurts, being male, Pagets disease, or prior radiation/chemotherapy -> osteosarcoma, chondrosarcoma, or Ewing sarcoma
- (if secondary) Paget’s disease, prior radiation/chemotherapy, other cancers -> metastasis to bone
