F. Wound infection1. May be superficial or deep wound2. Deep wound infection may lead to osteomyelitis3. Findings include erythema and swelling around suture line, increased drainage
and elevated temperature4. Treated with antibiotics; may require incision and drainage of wound or removal
of prosthesis if severe infection is presentG. Special complications in hip replacement
1. Femoral fracturea. occurs near distal end of femoral-shaft part of prosthesisb. occurs more frequently with elderly, clients with osteoporosis, or after

ii. rheumatoid arthritisiii. femoral neck fracturesiv. avascular necrosis of femoral head caused by steroidsv. failure of previous prosthesis
2. Surgical modalities
a. total hip replacement (hip arthroplasty) is the replacement of both articular surfaces of thehip joint, the acetabular socket and the femoral head and neck.b. hemiarthroplasty of the hip is the replacement of one of the articular surfaces, usually the
femoral head and neck.2. Surgical and immediate postoperative care
a. in first 24 hours, expect wound to drain blood and fluid up to 500ml.b. by 48 hours, wound drainage should be minimal
c. clients may require transfusions (autologous is preferred) due to blood loss duringsurgery.d. best pain management is patient controlled analgesia (PCA) for the first 48 hours,advancing to non-narcotic oral analgesics by the fourth or fifth postoperative day.e. monitor for signs of deep venous thrombosis (DVT) and pulmonary embolism (PE) or fatembolism

f. monitor neurovascular status of affected limb; color, temperature, presence of pulses.
3. Postoperative complications ORTHOPEDIC COMPLICATIONS
A. Venous thromboembolic problems1. Thrombophlebitis (TP)
a. inflammation of a vein with the formation of a blood clotb. incidence is greatest after trauma or surgery to legs or feet
B. Deep venous thrombosis (DVT)
1. Anterior tibial or femoral veins2. May be caused by immobility3. Findings include calf pain, positive Homan's sign4. Immediately after operations
a. anticoagulant therapyb. antiemboli stockings (usually)c. sequential compression device (possibly)
C. Pulmonary embolism (PE)1. Blood clot from systemic circulation enters pulmonary circulation2. Most commonly seen after hip fractures and total hip/knee replacements3. Occurs in approximately ten percent of patients undergoing hip arthroplasty4. May be caused by femoral vein manipulation during surgery and therefore occur
without signs of DVT
5. Findings include chest pain (pleuritic), sudden shortness of breath, tachycardia,palpitations, or change in mental status
6. If PE is suspected,do not leave client. Get charge nurse to notify health careprovider immediately
7. Diagnosis confirmed via ventilation/perfusion scan or pulmonary angiography8. Continuous IV heparin therapy usually prescribed
D. Fat embolism1. Definition: fat cells enter pulmonary circulation2. Associated with
a. multiple trauma accidentsb. multiple organ involvement
c. fractures of marrow producing bonesd. joint replacementse. insertion of intermedullary rods
3. Usually occurs 24 to 48 hours after the fractureE. Hemorrhage
1. Abnormal loss of blood from the body2. Most common in fractures of bone marrow producing bones
F. Wound infection1. May be superficial or deep wound2. Deep wound infection may lead to osteomyelitis3. Findings include erythema and swelling around suture line, increased drainage
and elevated temperature4. Treated with antibiotics; may require incision and drainage of wound or removal
of prosthesis if severe infection is presentG. Special complications in hip replacement
1. Femoral fracturea. occurs near distal end of femoral-shaft part of prosthesisb. occurs more frequently with elderly, clients with osteoporosis, or after
revision to total hip replacementc. primary finding is severe pain with ambulationd. diagnosis is confirmed with x-raye. depending on severity, treatment will be immobilization or open
reduction with internal fixation

2. Dislocation of hip prosthesisa. greatest risk during the first postoperative week but can occur at any time
within the first year.b. risk decreases as muscle tone of the hip increasesc. caused by flexion of the hip or poor prosthetic fitd. findings include pain and external rotation of the lege. treated by closed reduction under conscious sedation or open surgical
revisionH. Special complication in knee replacement: flexion failure
1. Client cannot flex knee 90 degrees two weeks postoperatively2. Treated with closed manipulation of the knee joint under general anesthesia
4. Nursing interventions
a. an abduction device is used during the first postoperative week while the client is in bedor sitting in a chairb. to keep abduction device in place, turn client by logrollingc. to prevent flexion of the hip, use fracture bedpand. client teaching
I. use of assistive devices; crutches, walker, raised toiletseat
II. methods to prevent dislocationIII. can resume sexual activity when suture line heals. To
avoid flexion of hip, client should be in dependentposition for three to six months
B. Total knee replacement1. Indications for surgery
a. osteoarthritisb. rheumatoid arthritisc. trauma
2. Surgical modalitiesa. metal or acrylic prosthesis, hinged or semiconstrainedb. choice of prosthesis depends on the strength of surrounding ligaments to provide jointstability

diabetes mellitus)B. gangreneC. trauma such as crushing injuries, burns, or frostbiteD. congenital deformities
E. malignant tumorc. Upper extremity indications
A. traumaB. malignant tumorC. infectionD. congenital malformations
d. Levels of amputation Objective of surgery is to eradicate the diseaseprocess while conserving as much of the extremity as possible
1. Toes and portion of the foot - usually as a result of trauma or infection. Causes minorchanges in gait or balance
2. Syme: disarticulation of ankle; stump can bear full weight, with prosthesis3. Below knee (BK) - preserves knee joint which facilitates use of prosthesis4. Knee disarticulation - at level of knee joint5. Above knee (AK) - measures undertaken to provide as much length to limb as possible6. Hip disarticulation - most often performed due to malignancy. Client cannot walk with
prosthesis.7. Below elbow (BE) - preserves elbow joint, thus eases use of prosthesis8. Above elbow (AE) - measures undertaken to provide as much length to limb as possible9. Staged amputation - used for infection. Guillotine amputation to remove infectious and
necrotic tissue is performed. After intensive antibiotic therapy, a second operation isperformed for skin closure.
A. amputate to most distal point that will heal successfullyB. determined by circulation and functional status
e. Potential postoperative complicationsA. hemorrhageB. infectionC. skin breakdown
f. Nursing interventionsA. pain management - usually relieved with narcotic analgesicsB. may require evacuation of accumulated fluid or hematomaC. muscle spasms may be relieved by heat or changing positionD. phantom limb pain

U. When performing a musculoskeletal assessment on a client with Paget's disease, note thesize and shape of the skull. The skulls of these clients will be soft, thick and enlarged.
V. Clients at high risk for acute osteomyelitis are: elderly, diabetics, and clients withperipheral vascular disease.
W. When clients receive corticosteroids long-term, evaluate them continually for side effects.X. Immunosuppressed clients should avoid contact with persons who have infections.Y. Steroids may mask the signs of infections, so client should promptly report slightest
change in temperature or other complaints.
Z. Photosensitive clients should avoid the sun, limit outdoor activities during peak sun hoursand wear sun block.
