• The branch of medical science dealing
  with prevention or correction of
  disorders and diseases of the
  musculoskeletal system
 Nursing of Pts. with Orthopedic
     Diseases or Disorders
• Objectives:
  –   Maintain body alignment

  becomes more common in females. Why?
• More than 150 types- classified in many
  different ways:
  –   Break in skin integrity
  –   Location or appearance
  –   Alignment status
  –   Force that caused fracture

 Fractures – Medical Treatment
Goals

• Realignment (Reduction)

• Establish sturdy union

• Restore function
       Fracture Reduction
Brings ends of broken bone into proper
   alignment
1. Closed: non-surgical

2. Open: surgical
          Fracture Fixation
Attempts to attach broken bone fragments
  together.
Performed during Open Reduction

ORIF: Internal use of rods, pins, nails, screws
 or metal plates to align and hold in place.

OREF: pins in bone attach to external frame.
 Pin track infection occurs in approx. 10%.
 Pin Care – sterile – nursing responsibility.
  Nursing Care Post-Op Open Reduction
• Assess Q1-2h for neurovascular
  complications
• Vital Signs Q4h, once stable
• Hemoglobin & Hematocrit
• Observe amount, type & characteristic of
  any drainage. Report amounts >100-150ml/hr
  after the 1st 4 hrs.
• Turn & Reposition @ least Q2h
• Deep Breathing, coughing, incentive
  spirometer
• What kind of meds?

•   Infection
•   Fat Embolism
•   Compartment Syndrome
•   Avascular Necrosis
•   Gas Gangrene
           Fat Embolism
• Fat globules released from marrow can
  occlude pulmonary vessels and lead to
  respiratory distress

• S/sx include: dyspnea, change in mental
  status (restlessness, agitation,
  confusion, stupor), tachypnea,
  tachycardia, fever (>103°), petecchial
  skin rash, diffuse rales.

  associated w/ pressure over compartment,
  pain w/ passive stretching of involved
  muscle, paresthesias, edema, pallor, weak or
  ≠ pulses, cyanosis

• Treatment: relieve pressure
        Avascular Necrosis
• Occurs whenever blood supply to bone is
  compromised
• Most often affects head & neck over
  femur and is a gradual process

  intermittent or constant pain w/ wt.
  bearing and any ROM limitation
• Usual treatment is joint replacement
               Gas Gangrene
• Gram + saprophytic bacterial infection (usually
  clostridium)

• S/Sx: change in mental status, fever, chills,
  decreased BP, increased P & R.

  wound site, and profuse drainage having a
  characteristic fruity odor

• FATAL without treatment
• AMPUTATION

• 1-2 small incisions
• Post-op
   – PT, special knee brace, avoid activities
     that stress knee

  – Return to sports 6-9 months after surgery

  – 9/10 report good – excellent results and
    satisfactory knee stability
           ACL Tx: Non-surgical

  impaired circulation,, congenital
  deformities, and infections. Most are
  elective

• Traumatic amputations can sometimes be
  reversed
        Amputation -Types
1. Closed – to create a wt. bearing
   residual limb. Uses a skin flap.

2. Open (Staged or Guillotine) – severed

  volume, pain control, infection
  prevention, Maintenance of adequate
  urinary output, and site preparation.

• Elective – antibiotics, any infections
  treated, and, if possible, resolved, prior

• Dx:
• Moist heat or cold therapy, analgesics,
  NSAIDS, retainer or guard, soft diet,
  Arthroscopy or other surgery last resort
       Carpal Tunnel Syndrome

• Highest incidence in obese middle-aged
  women, and in occupations w/ repetitious
  movements of hands or fingers, also in 3rd
  trimester of pregnancy

• 1 of 3 most common work-related conditions
  due to increased computer usage
Carpal Tunnel Clinical Manifestations
• Assessment: deficits in sensory mapping,
  increased tingling w/ gentle tapping on wrist
  (Tinnel’s Sign), forced flexion of wrists for 1
  minute or more produces numbness & tingling
  (+ Phelan’s sign)

• EMG: weakened muscle response to
  stimulation

• MRI: median nerve compression & flattening
         Carpal Tunnel S/Sx
• Burning, pain, numbness or tingling in hand

• Depression of soft tissue @ base of thumb
  on palmar surface
Carpal Tunnel Medical Management
• For Mild Sx:
  – Immobilization- splinting
  – Hydrocortisone acetate suspension
    injection
• For Severe Sx
  – Surgery – usually done only if there is
    accompanying muscle atrophy. Standard
    surgical treatment is to decompress the
    median nerve by sectioning the tansvers
    carpal ligament
  Carpal Tunnel Nursing Care
• Proper application of immobilizer

• ROM

• Education

• Decrease twisting or turning activities
  of wrist
    Carpal Tunnel Nursing Care

  metabolism of purines. Where do we find
  purines?

• Affects males 8-9x more than females
• Causes: Primary- hereditary
         Secondary- from medication, other
                     disease or idiopathic

• Occurs in mid-life. Why do you think that is?
                Gout S/Sx
• Excruciating pain, edema and inflammation
• Pain duration is variable
• Attack frequency is variable
• Tophi (calculi or stones made of sodium urate
  that develop in the periarticular tissue) may
  be present at the affected joint – usually
  the Great toe
• Edematous joint w/ red/purple discoration
  and heat
• Increased: temp, BP, P, R
• Complications: Kidney Stones
     Clinical Manifestations: Gout

CBC: may reveal anemia & leukocytosis

ESR elevated

X-Ray: cysts, toe bone pockets

Synovial Fluid Analysis: uric acid crystals
     Medical Management of Gout
                     Medications

       production
    2. probenecid (Benenid) increases uric acid
       excretion by kidneys
    3. sulfinpyrazone (Anturane)- prevent tophi dev.
           Nursing Care Gout
