Musculoskeletal Care Modalities Slide 2 Managing care of the patient in Cast: A rigid, external immobilizing device Is used to: 1.Immobilize a reduced Fracture ( allow the mobilization of the pt) 2.Correct a deformity 3.Apply uniform pressure to underlying soft tissue 4.Support and stabilize weakened Joint Slide 3 Types of Casts: 1.Short arm cast 2.Long arm cast 2.Short leg cast 3.Long leg cast 3.Walking cast ( long or short) reinforced for strength 4.Body cast: encircle the trunk 5.Shoulder spica cast: a body jacket that enclosed the trunk and the shoulder and elbow 6.Hip spica cast: enclose the trunk and lower extremity ( double hip spica cast ( includes both legs Slide 4 Casting Materials: Plaster: Rolls of plaster bandage, need 24 to 72 hrs to dry completely Nonplaster: Fiberglass cast ( lighter in wt, stronger, water resistant), has pores so diminish skin problems Slide 5 Slide 6 Slide 7 Slide 8 Slide 9 Long-Arm and Short-Leg Cast and Common Pressure Areas Slide 10 Teaching Needs of the Patient With a Cast Prior to cast application Explain condition necessitating the cast Explain purpose and goals of the cast Describe expectations during the casting process: eg, the heat from hardening plaster Cast care: keep dry; do not cover with plastic Positioning: elevation of extremity; use of slings Hygiene Activity and mobility Slide 11 Cont Explain exercises Do not scratch or stick anything under the cast Cushion rough edges Report the following signs and symptoms: persistent pain or swelling; changes in sensation, movement, skin color, or temperature; and signs of infection or pressure areas Required follow-up care Cast removal Slide 12 Nursing Process Assessment of the Patient With a Cast Prior to casting Perform general health assessment Evaluate emotional status Determine presenting signs and symptoms and condition of the area to be casted Knowledge Monitor neurovascular status and the potential for complications Slide 13 Nursing Process Diagnosis of the Patient With a Cast Deficient knowledge Acute pain Impaired physical mobility Self-care deficit Impaired skin integrity Risk for peripheral neurovascular dysfunction Slide 14 Collaborative Problems/Potential Complications Compartment syndrome Pressure ulcer Disuse syndrome Delayed union or nonunion of fracture(s) Slide 15 Interventions Relieve pain Elevate to reduce edema Apply ice or cold intermittently Implement position changes Administer analgesics Unrelieved pain may indicate compartment syndrome; discomfort due to pressure may require change of cast Muscle setting exercises: see Chart 67-3 Patient teaching: see Chart 67-4 Slide 16 Interventions (cont.) Heal skin wounds and maintain skin integrity Treat wounds to skin before the cast is applied Observe for signs and symptoms of pressure or infection Pad cast and cast edges Patient may require tetanus booster Maintain adequate neurovascular status Assess circulation, sensation, and movement Five P s Notify physician at once of signs of compromise Elevate extremity no higher than the heart Encourage movement of fingers or toes every hour Slide 17 Managing patient with an External fixator: Are used to manage open fractures with soft tissue damage. They provide stable support for severe comminuted (crushed or splintered) fractures while permitting active treatment of damage soft tissue. Nursing intervention: Prepare the patient psychologically Cover sharp points on the fixator or pins to prevent injuries Elevate the extremity to reduce swelling Assess neuromuscular status every 2 hrs Assess pin site for sign of infection and loosening of the pin Pin care Encourage isometric and active exercise within the limit of tissue damage. Later the nurse help the patient to mobilize within the prescribed weight bearing limit Teaching patient self care Slide 18 External Fixation Devices (cont.) Slide 19 Slide 20 Managing the patient in Traction: Is used as short-term intervention until other modalities, such as external or internal fixation are possible. Traction: is the application of a pulling force to a part of the body Is used to minimize muscle spasm, to reduce fractures, align and immobilize fractures, to reduce deformity. The effect of traction is evaluated by radioactive studies. Slide 21 Traction (cont.) All traction needs to be applied in two directions. The lines of pull are vectors of force. The result of the pulling force is between the two lines of the vectors of force. Slide 22 Managing the patient in Traction (cont ): Principle of effective traction: 1.Countertraction must be maintained for effective traction 2.Must be continuous to be effective 3.Never interrupted 4.Weight are not removed 5.The patient must be in in good body alignment in the center of the bed 6.Ropes must be unobstructed 7.Weight must hang freely Slide 23 Types of tractions: I. Skin traction: is used to control muscle spasm and to immobilize an area before surgery. No more than 2-3.5 kg of traction should be used, pelvic traction 4.5 to 9 kg depending on the patient weight Complications: Skin breakdown, nerve pressure (drop foot), and circulatory impairment ( DVT) Nursing interventions: 1.Ensuring effective traction 2.Monitor and managing potential complications Slide 24 Skin Traction Slide 25 Types of tractions (cont ): II. Skeletal traction: applied directly to the bone by using metal pin or wires. Most frequently used to treat fracture of long bones and the cervical spine. Is a surgical procedure. Skeletal traction uses 7-12 kg, as the muscle relax the traction weight is reduced to prevent fracture dislocation and to promote healing After removing the traction cast or splint are then used to support the healing bone. Slide 26 Skeletal Traction Slide 27 Nursing Interventions: 1.Maintaining effective traction: the nurse should not remove wt from skeletal traction unless life-threatening situation occurs 2.Maintaining positioning: such as the foot to prevent footdrop (planter flexion), inward and outward rotation. 3.Preventing skin breakdown 4.Monitoring neuromuscular status 5.Providing pin site care 6.Promoting exercise Assess sensation and movement Assess pulses, color capillary refill, and temperature of fingers or toes Assess for indicators of DVT Assess for indicators of infection Slide 28 Joint Replacement: Total Hip Replacement: Is the replacement of a severely damaged hip with an artificial joint Indication: arrithritis, femoral neck fracture, failure of previous reconstructive surgeries, and problems resulting from congenital hip diseases. Slide 29 Slide 30 Slide 31 Cont Nursing interventions: 1.Prevent dislocation: A.positioning the leg in abduction, B.don t turn the patient in the affected side, C.never flex the hip more than 90 degree ( D.don t elevate the head of the bed more than 60 degree E.protective positioning include maintaining abduction, avoiding internal and external rotation, hyperextension, and a cute flexion Slide 32 Cont . 2. Monitoring wound drainage 3. Preventing DVT 4. Prevent infection 5. Teach patient self care 6.

The rate of bone resorption is greater than the rate of bone formation, resulting in a reduced total bone mass. The bones become porous, brittle, and fragile Result in compression fractures of the thoracic and lumber spine, fractures of the neck, intertrochanteic region of the femur, and colle s fracture of the wrist Pathophysiology: Loss of bone mass over time due to Aged-related loss: Decreased calcitonin, decreased estrogen ( which prevent bone breakdown), parathyroid hormone increases with age result in increase bone Resorption Slide 49 Pathophysiology of Osteoporosis Slide 50 Risk factors: see chart 68-7 Assessment and diagnostic findings: Routine X-ray, and bone sonometer Lab. Studies: Serum Ca, Serum Ph, urine calcium excretion, ESR Medical Management: Adequate balanced diet rich in calcium and Vit D Regular weight bearing exercise promotes bone formation Pharmacological therapy: Hormonal replacement therapy ( look for side effect of estrogen and progesterone replacement therapy which result in cancers thus frequent breast examination is recommended ) Alendronate alternative to Hormonal replacement therapy: inhibiting osteoclast function and dedcreases bon loss Calcitonin: suppress bone loss Slide 51 Progressive Osteoporosis Bone Loss and Compression Fractures Slide 52 Osteoporosis Manifestations : Loss of height Progressive curvature of spine Low back pain Fractures of forearm, spine, hip Development of dowager s hump Dorsal kyphosis Cervical lordosis Slide 53 Typical Loss of Height Associated With Osteoporosis and Aging Slide 54 Prevention Follow a balanced diet high in calcium and vitamin D throughout life Use calcium supplements to ensure adequate calcium intake: take in divided doses with vitamin D Regular weight bearing exercises: walking Weight training stimulates bone mineral density (BMD) See Chart 68-8 Slide 55 Musculoskeletal Infections: Osteomylitis Is an infection of the bone through three ways ( extension of soft tissue infection, Direct bone contamination from bone surgery, Hematogenous spread (blood born). More difficult to eradicate than soft tissue infection Pathophysiology: Staphylococcus aureus causes 70% to 80% of bone infection Process of infection (inflammation, edema, thrombosis of the blood vessels result in ischemia with bone necrosis, which may progress to form bone abscess Clinical manifestations: chills, high fever, rapid pulse, pain, swollen area, and tenderness and drainage Assessment and diagnostic Findings: X-ray (shows soft tissue swelling, later bone decalcification and necrosis), MRI, Lab test (leukocytosis, and increased ESR), wound and blood culture Slide 56 Slide 57 Osteomyelitis Deep sepsis after arthroplasty may be classified as follows: Stage 1, acute fulminating: occurring during the first 3 months after orthopedic surgery; frequently associated with hematoma,drainage, or superficial infection Stage 2, delayed onset: occurring between 4 and 24 months after surgery Stage 3, late onset: occurring 2 or more years after surgery, usually as a result of hematogenous spread Slide 58 Cont .. Prevention: treat all sources of infection, Aseptic surgery, Prophylactic antibiotics, Aseptic postoperative care. Medical management: Pharmacological therapy: Intravenous antibiotic according to the wound culture Surgical management: expose the bone surgically to remove infected and necrotic materials and irrigating the area with normal saline, direct application of antibiotics surgical (d bridement).

Nursing Interventions/Patient Education Slide 67 Joint Dislocation articular surfaces of the joint are not in contact A traumatic dislocation is an emergency with pain change in contour, axis, and length of the limb and loss of mobility Most common Shoulder Acromioclavicular joints Subluxation Partial dislocation Slide 68 Fractures: Is a break in the continuity of bone and is defined according to type and extent Occurs when the bone is subjected to stress greater than it can absorb. Can cause by a direct blow, crushing force, sudden twisting motion, and extreme muscle contraction. Slide 69 Types of fractures: 1.Complete fracture: break across the entire cross- section of the bone and is frequently displaced 2.Incomplete fracture: (green stick fracture) the break occur through only part of the cross-sectional of the bone 3.A comminuted fracture: fracture has several bone fragments 4.Closed fracture: simple fracture does not produce a break in the skin 5.Compound, complex fracture (open fracture): is one in which the skin or mucous membrane wound extends to the fracture bone Slide 70 Cont Grade I: clean wound less than 1 cm Grade II: larger wound without extensive soft tissue damage Grade III: is highly contaminated, has extensive soft tissue damage, and is the most severe Slide 71 Types of Fractures (cont.)
