67
Collaborative Care/Nursing Therapeutics Goal for Amputations
Preserve extremity length as necessary
68
Health Promotion for Amputations: Monitor
Changes of the extremity involved such as:
- skin color changes
- decrease or absence of sensation
- pulsation/presence of adequate circulation
69
Amputations: Preoperative Management
o Reinforce information: reason for amputation, proposed prosthesis, mobility training program
o Discuss about phantom limb sensation
70
Amputations: Postoperative Management
o Assess, monitor VS and dressing
o Maintain *STERILE technique on wound dressing changes
o Pain Management
71
Amputations: Acute Interventions
* Notify surgeon immediately if bleeding occurs

* Bandaging of the residual limb for proper prosthesis fitting
* Compression bandage applications
* Minimized edema of the ritual limb
* Active ROM
72
Osteomyelitis
a severe infection of the bone, bone marrow and surrounding tissues
73
Osteomyelitis is most often caused by
Staphylococcus aureus
74
Limited supply of blood to the bone can cause
Limited amount of antibodies to the infection site -> more time for bacteria to multiply
75
Causes of Osteomyelitis include
```
Indirect Entry:
-Blunt Trauma
-Vascular Insufficiency (DM)
Direct Entry:
-Open wounds
-Foreign bodies (implant or orthopedic prosthetic devices)
```
76
Common Sites for Osteomyelitis
Pelvis
Tibia
Vertebrae
77
Pathophysiology of Osteomyelitis
* Predisposing or precipitating factors (entrance of microorganisms)
* Lodge to area with slow circulation
* Microorganism multiplies
* Increase pressure in the bone area
* Ischemia/vascular compromise
* Infection to the bone cortex
* Cortical devascularization
* Spread to other parts
78
Clinical Manifestations of Osteomyelitis: Localized
```
o Bone pain
o Swelling
o Tenderness
o Warmth in site
o Restricted movement
o Drainage (serosanguinous to purulent drainage)
```
79
Clinical Manifestations of Osteomyelitis: Systemic
```
o Fever
o Night sweats
o Chills
o Restlessness
o Nausea and malaise
```
80
Diagnostic Studies of Osteomyelitis

o Care of access device
o Dressing change
85
Sequestrum
- Dead bone
| - May also be a reservoir for microorganisms that spread systemically -> lungs and brain
85
Involucrum
- new bone (makes it difficult for successful antibiotic therapy)
- Antibiotics and WBC have difficult time reaching sequestrum
86

- usually caused by high speed motor vehicular accident or skiing
- can cause life threatening hemorrhage
91
Closed book fracture (lateral compression)
Lateral force impact
92
Treatment for Stable, Nondipslaced Pelvic Fractures
