5 Osteoporosis Increased Risk Family history Female Menopause-related low estrogen females, low testosterone malesMedicationsLifestyleFamily history, especially small frame Asians & white femalesFemaleMenopause-related low estrogen females, low testosterone malesUse of anticonvulsants, corticosteroids, heparin, tetracycline, thyroid supplementsLifestyle: inactive, cigarette &/or alcohol use, low lifetime calcium intake
6 Osteoporosis Prevention Diet Calcium supplements Stop smoking Alcohol and caffeine intakeweight-bearing exerciseSunlightIncrease dietary calcium & vitamin D: milk & milk products best sources; sardines, clams, oysters, salmon, dark green leafy vegetablesTeach calcium in diet: Calcium supplements post menopauseStop smokingDecrease alcohol and caffeine intakeIncrease weight-bearing exercise: at least 30 minutes 3 times per weekIncreased exposure to sunlight: vitamin D increases calcium absorption in intestine
7 Osteoporosis Diagnosis Dual-energy x-ray absorptiometry (DEXA) scan Qualitative ultrasound (QUS) of heel or calcaneusDiagnosisDual-energy x-ray absorptiometry (DEXA) scan measures bone mineral density in hip, wrist or vertebrae: best toolQualitative ultrasound (QUS) of heel or calcaneus: low cost screening tool
8 Osteoporosis Collaborative Management Replace estrogen or testosterone Raloxifene (Evista)Biphosphonates: Alendronate (Fosamax) and risedronate (Actonel)Teriparatide (Forteo)Ibandronate sodium (Boniva)Calcitonin (Miacalcin)Sodium fluorideCollaborative Management: retard bone resorption:Replace estrogen after menopause orRaloxifene (Evista): mimicks estrogen effect on bones without risks of estrogenBiphosphonates: Alendronate (Fosamax) and risedronate (Actonel) inhibit bone resorptionTeriparatide (Forteo): synthetic parathyroid increases new bone formationIbandronate sodium (Boniva): both prevents bone loss & increases bone densityCalcitonin (Miacalcin): increases bone formation, decreases resorptionSodium fluoride stimulates bone formation

13 OsteoarthritisOsteoarthritis, formerly called degenerative joint disease (DJD), is the most common joint disorder. Intra-joint cartilage erodes over time leading to synovitis (inflammation) and subluxation (joint dislocation) and joint deformities. This leads to marked immobility, pain, muscle spasm and inflammation.Reprinted with permission: Charles J. Eaton, M.D. of The Hand CenterReprinted with permission: DePuy Orthopaedics, Inc.

23 Key Treatments Closed reduction Immobilization Open reduction Splint CastOpen reductionClosed reduction: Manual traction applied to move bones back together, then casted to maintain position. Done under anesthesia (could be conscious sedation in ER); will reduce pain and muscle spasm.Open reduction involves rods, plates, screws followed by casting in O.R.Open reduction; External FixationNational Institutes of Health Osteoporosisand Related Bone Diseases National ResourceCenter
24 Cast Care Prevent indentations when wet Elevate uniformly Air dry CSM – What am I looking for?No scratching implements!Cast CarePrevent indentations when wet: Handle wet cast with palms, use pillows length-wise to maintain even pressure – cover pillows with towels to promote drying;Elevate uniformly: turn patient/cast to expose all wet areas to air.Air dryColor, Sensation, Movement (CSM): Assess q 15 minutes x 4 hours, then q 1 hour until 24 hours post castingTeach: No scratching implements
25 Skin Traction To decrease muscle spasm Weight 5-7 pounds attached w/ adhesive tapeUsed before surgical repairCheck sling, tape for placementKeep pulley, weights in placeSkin TractionTo decrease muscle spasmFive-to seven-pound weights attached to the skin to indirectly apply pulling force on the bone. If traction is temporary, or if only a light or discontinuous force is needed, then skin traction is the preferred treatment. Because the procedure is not invasive, it is usually performed in a hospital bed.Weight 5-7 pounds attached w/ adhesive tapeWeights are attached either through adhesive or nonadhesive tape, or with straps, boots, or cuffs. Keep the straps or tape loose enough to prevent swelling and allow good circulation to the part of the limb beyond the spot where the traction is applied. The amount of weight that can be applied through skin traction is limited because excessive weight will irritate the skin and cause it to slough off.Used before surgical repairMake sure the limb stays aligned, skin care so it does not become sore and irritated. The patient should also be alert to any swelling or tingling in the limb that would suggest that the limb has been wrapped too tightly.Check sling, tape for placementKeep pulley, weights in placePhoto Source: Royal College of Surgeons of Ireland (RCSI), Creative Commons
26 Buck’s Traction Hip fracture assessment What to do immediately? Buck’s traction assessmentsWhat should be done later?What teaching is needed?Buck’s: NURSING, Nov 2003 by Sprauve, DoyleanAGNES HIGHTOWER, 85, is brought to your ED after falling onto her right hip.She's alert and oriented and appears well nourished. She says she now has severe pain in her right hip and can't move it.What's the situation?Ms. Hightower's right leg is externally rotated and appears shorter than the left one. Her right posterior tibial and dorsalis pedis pulses are +2. Her right leg is cool to touch with limited range of motion. Her left leg is normal.An X-ray of the right hip reveals an intertrochanteric fracture (a fracture between the greater and lesser trochanter of the femur). No osteoporotic changes to the bone are seen on X-ray. The primary care provider calls for an orthopedic consultation.What's your assessment?Ms. Hightowers fracture needs to be treated promptly to avoid tissue necrosis, blood loss, and infection. Pain management is also a priority.What must you do immediately?Start an I.V. line for fluids and keep Ms. Hightower N.P.O. before surgery. Administer parenteral analgesics as prescribed and a muscle relaxant if prescribed. Monitor her vital signs and level of consciousness frequently, watching for respiratory depression and signs of shock, such as decreases in level of consciousness and urine output.To stabilize the fracture, Ms. Hightower s right leg is placed in Buck's traction, which includes a foam boot. A weight attached to the boot pulls the bone fragments into alignment. Buck's traction prevents further traumatic injury and reduces muscle spasms.However, traction puts a patient (especially an elderly one) at increased risk for complications of immobility, including skin breakdown, deep vein thrombosis (DVT), pulmonary embolism (PE), and pneumonia. Assess Ms. Hightower's skin every 2 hours. Place her on a pressure-reducing mattress and provide an overhead trapeze bar to help her with bed mobility. Monitor leg sensation and movement every 2 hours; the traction weights put pressure on her peroneal and tibial nerves.Regularly assess her feet and legs for pain, temperature, pulses, capillary refill, color, and edema. Apply compression stockings to promote venous return and reduce the risk of DVT and PE.Obtain preoperative lab studies and prepare Ms. Hightower for surgery. Although she has fewer reserves than a younger patient, she has no preexisting medical conditions, so her prognosis for successful surgery and functional recovery is good. Twenty-four hours after her fall, Ms. Hightower undergoes a successful open reduction and internal fixation of her right hip.What should be done later?After surgery, Ms. Hightower is transferred to the orthopedic unit, where she'll be monitored for complications such as hemorrhagic shock, neurovascular impairment, and fat embolism (a risk in patients with long bone fractures). The primary care provider orders low-molecular-weight heparin to prevent DVT and PE. Manage Ms. Hightower's pain, encourage early ambulation and good nutrition, and maintain her fluid balance.Monitor the amount and character of drainage from the surgical site and her intake and output, assess her vital signs, and monitor hemoglobin and hematocrit levels. She'll have I.V. fluids and a patient-controlled analgesia pump.Ms. Hightower will have a risk assessment for falls, so that the cause of her fall (for example, overmedication) can be determined and she can be educated about fall prevention.Buck’s TractionSource: DeRoyal Patient Care
27 Other Skin Traction Russell’s Cervical Thomas splint Bryant’s Pelvic Russell's Traction: Traction composed of Buck's extension on the lower leg.Cervical Traction: Traction applied to the neck by use of a head halter.Thomas Splint: A full leg splint used mostly in emergency transport situations.Bryant's Traction: Traction using vertical suspension of the legs. The child's pelvis is elevated off of the bed.
28 Skeletal Traction Weight 25-40 pounds Are the ropes on the pulleys? Are the weights hanging free?Where are the knots?Monitor CSMPin care?Skin careSkeletal TractionSkeletal traction may be configured in two ways: straight/running traction or balanced suspension traction.In straight or running traction the counterforce is supplied by the patient’s body with the bed in one of these positions: 1) flat; 2) tilted away from the traction pull (place bed in Trendelenburg/reverse Trendelenburg position); or 3) with the head of the bed elevated and/or knee catch.The purposes of traction are to:reduce fractures or dislocationsmaintain body or limb alignmentdecrease muscle spasms and relieve paincorrect, lessen or prevent musculoskeletal deformitypromote rest of an injured or diseased partpromote exerciseNursing ManagementWeight poundsAre the ropes on the pulleys?Are the weights hanging free?Where are the knots? (should not be on pulleys)Monitor CSMPin careSkin care
29 Balanced Suspension Counter-traction by weights Check ropes, knots, weightsAre traction bars tightened?Is patient in alignment?How do pin sites look?When can I remove weights?In balanced suspension traction, slings or splints are used to support the affected part. Although the bodyprovides some countertraction, further countertraction is achieved by additional balanced weights attached to the overhead frame. These keep a pull directly opposite and equal to the traction force pull.Assess traction apparatus effectiveness every 8 hours by ensuring that:• ropes are on center of pulley track and are not frayed; knots are secured• weights are hanging freely, away from bed and not touching floor•spreader bars, foot plate, or splints do not touch foot of bed• overhead frame/ traction bars are tightly fastenedAssess for correct positioning of traction and alignment of affected extremityand alignment of entire body every shift.Assess muscle strength, range of motion and ability to perform ADL’s every shift.Assess pin sites/open wounds every 8 hours for:• skin tenting (ensure skin is not attached to pin)• signs and symptoms of infection• persistent erythema or skin breakdown• bleeding• skin tension• drainageREPORTABLE CONDITIONS/ Notify MD for:•diminution of neurovascular status•tenting, erythema, bleeding, or serous/purulent drainage around pin sites•severe pain/ muscle spasms unrelieved by medication and/or repositioning•persistent erythema or skin breakdown in areas other than pin sites•disruption of traction•skin coolness or mottling in affected extremityAttach an overhead frame with trapeze to facilitate patient mobility and independence.Encourage patient to perform ROM exercises of unaffected extremities and unaffected joints of extremity in traction (maintaining body extremity alignment) every two hours while awake.Encourage dorsi-/plantar flexion of feet and ankle circumduction exercises every 2 hours while awake.TRANSPORT: Maintain traction at all times.SAFETY: Do not remove or add weights to skeletal traction without physician’s order.Never take patient out of traction without a physician’s order.
30 Spinal Traction Where are the knots? Are the weights hanging free? What do the pin sites look like?How do I turn the patient?How can I make the patient comfortable?- Turn patient by using logrolling technique (or use Stryker Frame, Circolectric bed, Roto Rest bed)- Maintain body alignment when in side position with full-length bath blanket roll and pillow between knees- Obtain prism glasses by initiating referral to Occupational Therapy.- Align the patient’s body with the pull of the traction- Position head properly to maintain countertraction- Reposition every 2 hours unless medically contraindicated.

58 Percentage of Burn Injury Rule of Nine: This formula divides the body into parts considered to be 9% (arms, head) to 18% (legs, front, back) of total body skin surface in adults. The small child has a different surface area breakdown. The burn size (as % of total) can then be used in the resuscitation formula.Source: Burn diagrams courtesy of BioTel Emergency Medical Service (EMS), Texas Department of Health,
59 Emergency ManagementExcessive leakage of plasma, especially in the first eight hours post-burn, causes hypovolemia, hypoproteinemia, hemoconcentration, electrolyte imbalances and acid base disturbances. In the absence of prompt fluid replacement, burn shock is imminent.Emergency ManagementIn burns greater than 30% BSA, a generalized capillary permeability occurs due to systemic hypoproteinemia and inflammatory mediators, resulting in edema formation in non-burned tissues as well. Excessive leakage of plasma, especially in the first eight hours post-burn, causes hypovolemia, hypoproteinemia, hemoconcentration, electrolyte imbalances and acid base disturbances. Plasma volume is reduced by as much as 23-27%, with a reduction in cardiac output and an increase in peripheral vascular resistance. In the absence of prompt fluid replacement, burn shock is imminent.
60 Fluid Resuscitation Initial 24 hours: Lactated ringer's 2-4 ml/kg/%burn/24 hours - given in the first 8 hours post-injury.Additional fluid required for inhalation injury.Maintain urine output of 30 ml/hr.5% albumin – keep albumin >2.5 gm/dlFluid Resuscitation The most crucial aspect of early care of the burn patient is prompt initiation of volume replacement of large quantities of salt-containing fluids sufficient to maintain adequate perfusion of vital organs. Many formulas for burn resuscitation have proven clinically efficacious, and each differs in volume, sodium, and colloid content. Currently, the most widely used Adult formulas are the Parkland (Baxter) formula and the modified Brooke formula, which deliver Ringer's lactate solution (LR) at 4 ml/kg/%burn and 2 ml/kg/%burn respectively, during the first 24 hours post-burn.In each case, half of this volume is administered in the first eight hours post-burn. The rate is adjusted hourly to assure a urinary output of 30 ml/hr in adults and 1 ml/kg/hr in children. Serum albumin is replaced to keep levels >2.5 gm/dl. NOTE: A 60 kilogram adult with a 40% body surface area burn will receive ml of Lactated Ringer’s in the first 24 hours post-burn; ml of this will be given in the first 8 hours post-burn. That means the patient will receive ml/hr for the first 8 hours. This is calculated from the time of the burn, not from the time of admission.
61 Monitoring Fluid shift lasts 24 to 72 hours. Hematocrit, electrolytes, osmolality, calcium, glucose, albumin Urine output >30 ml/hrMyoglobinuria and hemoglobinuriaPulse rate and pulse pressureNormal sensorium and adequate peripheral capillary refillMonitoringThe acute resuscitation period following burn injury generally lasts 24 to 72 hours. Fluid shifts are rapid. Serial determinations of hematocrit, serum electrolytes, osmolality, calcium, glucose and albumin can help direct appropriate fluid replacement. Persistent metabolic acidosis on arterial blood gases may be indicative of ongoing hypoperfusion from hypovolemia. The single best monitor of fluid replacement is urine output. Acceptable hydration is indicated by a urine output of more than 30 ml/hr is an adult (0.5 ml/kg/hr) and at least 1 ml/kg/hr in a child. Diuretics are generally not indicated during the acute resuscitation period. Patients with high voltage electrical burns and crush injuries have an increased risk of renal tubule obstruction from myoglobinuria and hemoglobinuria. Urine output should be maintained at 1-2 ml/kg/hr, if pigment can be seen in the urine and the urine alkalinized with IV sodium bicarbonate or acetazolamide with IV mannitol to aid in diuresis and to act as a free radical scavenger. Pulse rate and pulse pressure are more sensitive indicators of hemodynamic status than blood pressure. Hypotension is a late finding in burn shock. Normal sensorium and adequate peripheral capillary refill are additional clinical indicators of adequate organ perfusion. Invasive hemodynamic monitoring with central venous catheters, arterial lines, and Swan Ganz catheters is usually not needed in the absence of a severe inhalation injury, and discretion is advised. Pulmonary artery lines especially carry an inordinate risk of sepsis, thrombophlebitis and endocarditis in thermal injury patients. (Shriner’s Hospital burn care orientation:
