Fall 2019 - Spring 2020 1
OSTEOMYELITIS Severe infec*on of bone, bone marrow, and
surrounding soL *ssue Most common microorganism is Staphylococcus aureus, but can be caused by variety of organisms
What are 3 reasons a person would get osteomyeli*s? Fall 2019 - Spring 2020 2
Case Study • 74-‐year-‐old man brought into the ED
by his daughter • CC: Fever, nausea, and constant pain
in his leL leg • PMH: DM and foot ulcers • Examina*on: LLE indicates
inflamma*on with restricted movement secondary to pain
• V.R.’s WBC count is elevated • CT scan reveals severe inflamma*on of
his *bia and surrounding soL *ssue • He is admiYed to the hospital
² What previous (oxygena:on) disease increases risk for osteomyeli:s?
• V.R.’s daughter asks how his bone could get an infec*on.
² What type of infec*on is in the CC? ² What could it turn into? ² How would you explain the disease
process and likely cause?

Fall 2019 - Spring 2020 3
E*ology and Pathophysiology
• Direct entry – Via open wound – Foreign body presence
• Microorganisms grow → increase pressure in bone → ischemia and vascular compromise
• Infec*on spreads through bone → cortex devasculariza*on and necrosis
Fall 2019 - Spring 2020 4
Clinical Manifesta*ons Acute Osteomyeli*s: < 1 month in dura*on
• Local manifesta:ons
– Pain that worsens with ac*vity; is unrelieved by rest
– Swelling, tenderness, warmth
– Restricted movement
• Systemic manifesta:ons – Fever – Night sweats – Chills – Restlessness – Nausea – Malaise – Drainage (late)
Fall 2019 - Spring 2020 5
Clinical Manifesta*ons Chronic Osteomyeli*s: > 1 month or has failed to respond to ini*al an*bio*c
treatment
• Con*nuous and persistent or process of exacerba*ons and remissions
• Systemic manifesta*ons reduced
• Local signs of infec*on more common – Pain, swelling, warmth
• Granula*on *ssue turns to scar *ssue → avascular → ideal site for microorganism growth → cannot be penetrated by an*bio*cs
Fall 2019 - Spring 2020 6
Case Study
• Based on V.R.’s history and presenta*on, how would you classify his osteomyeli*s? • __ __ __ __ __

Consider psychosocial ramifica*ons Fall 2019 - Spring 2020 18
Low Back Pain
Acute Low Back Pain • Few defini*ve diagnos*c
abnormali*es • Straight-‐leg raising test
– Posi*ve for disc hernia*on when radicular pain occurs
• X-‐ray, CT, MRI only for trauma or suspected systemic disease
Chronic Low Back Pain • Spinal stenosis
– Narrowing of spinal canal (lumbar vs. cervical)
– Pain in low back, radiates to buYock and leg
– ↑ With walking/ prolonged standing
– Numbness, *ngling, weakness, heaviness in legs and buYocks
– Pain ↓ when bends forward or sits down
Fall 2019 - Spring 2020 19

– Brace • Ac*vity Restric*ons:
– Brief period of rest may be necessary; Avoid prolonged bed rest*
– No LiLing, bending, twis*ng, prolonged siqng
Health Promo*on: • Proper body mechanics • “Back School” • Appropriate body weight • Proper sleep posi*oning;
firm maYress • Stop smoking • Ways to prevent addi*onal
episodes • Strengthening and stretching
exercises (PT/OT)
Goal is to make an episode of acute low back pain an isolated incident
Fall 2019 - Spring 2020 20
Low Back Pain Pa*ent Teaching • Do:
– Sleep in a side-‐lying posi*on with knees and hips bent

Fall 2019 - Spring 2020 22
When caring for a pa*ent following a lumbar laminectomy, the nurse should a. Place a pillow between the pa*ent’s legs before
turning to the side. b. Elevate the head of the bed 30 degrees and then turn
the pa*ent to the side. c. Ask the pa*ent to flex the knees and push the heels
into the bed during turning. d. Have the pa*ent grasp the side rail on the opposite
side of the bed to help with turning.

bilateral salpingo-‐oophorectomy and refuses estrogen therapy.
Fall 2019 - Spring 2020 35
OSTEOPOROSIS Why is it more common in women? • Lower calcium intake • Less bone mass • Bone resorp*on begins
earlier and becomes more rapid at menopause
• Pregnancy and breasyeeding
• Longevity Screening Guidelines: • Ini*al bone density test in
women over age 65 • Currently no evidence of
benefit for screening in men
Fall 2019 - Spring 2020 36
Interprofessional Care –OSTEOPOROSIS Focus on
1. Proper nutri*on 2. Calcium supplements 3. Exercise 4. Preven*on of fractures 5. Drug therapy
Clinical Manifesta:ons: • Occurs most commonly in
spine, hips, and wrists • Back pain • Spontaneous fractures • Gradual loss of height • Kyphosis or “dowager’s hump “ Diagnos:c Studies: • History and physical exam • X-‐ray and lab studies not
diagnos*c • Bone mineral density
(BMD)Quan*ta*ve ultrasound (QUS)Dual-‐energy x-‐ray absorp*ometry (DXA)
Fall 2019 - Spring 2020 37
Interprofessional Care -‐OSTEOPOROSIS Adequate calcium intake: • 1000 mg/day for
– women ages 19-‐50 years – Men ages 19-‐70 years
• 1200 mg/day for – Women 51 years or older – Men 71 years or older
Fall 2019 - Spring 2020
Supplemental calcium: • Take in divided doses • Calcium carbonate
– 40% elemental calcium – Take with meals
• Calcium citrate – 20% elemental calcium – Less dependent on stomach acid
• Vitamin D necessary for calcium absorp*on/func*on; bone forma*on
• Sunlight for 20 minutes adequate • Supplemental (800-‐1000 IU/day)
– Postmenopausal – Older adults – Homebound/long-‐term care – Minimal sun exposure
38
Interprofessional Care -‐OSTEOPOROSIS • Weight-‐bearing exercise:
– Build up and maintain bone mass
– Increase strength, coordina*on, balance
– Walking, hiking, weight training, stair climbing, tennis, dancing
• Preven:on of Fracture: – Quit smoking – Decrease alcohol intake
Drug therapy to inhibits bone resorp:on: • Bisphosphonates
– Side effects: anorexia, weight loss, gastri*s
– Proper administra*on • Take with full glass of water • Take 30 minutes before food or
other meds • Remain upright for at least 30
minutes • Calcitonin
– Give IM form at night to minimize side effects
– Alternate nostrils when using nasal form – Calcium supplementa*on is needed
• Selec*ve estrogen receptor modulators – Raloxifene (Evista) – Reduces bone resorp*on
Fall 2019 - Spring 2020 39
