Q

Gerontologic Considerations: Effects of aging on the musculoskeletal system:

A
  • Bone remodeling is altered
  • Muscle mass and strength decrease
  • Loss of motor neurons
  • Tendons and ligaments less flexible
  • Joints more likely to be affected by osteoarthritis
  • Osteoarthritis and osteoporosis not normal consequences of aging

Q

Changes with aging:

A
  • Total number of bone cells decrease
  • Decline of tissue loses elasticity, muscle lose bulk, tone and strength
  • Bone resorbtion is more rapid than bone growth
  • calcium is lost from the bone
  • calicium loss makes bones softer and prone to fractures
  • leads to osteoporosis
  • -articular cartilege degenerates in weight bearing joints and heals slower

Q

Acute low back pain:

A
  • Def: activity intolerance d/t LBP or back related symptoms of 3 months or less. It becomes chronic if it last longer than 12 weeks.
  • LBP: affects areas below the ribs and gluteus muscles, often radiates to the thigh, sciatic pain from sciatic nerve impairment

Q

Low Back Pain: Etiology:

A

A common problem because the lumbar region bears most of the weight of the body; is the most flexible region of the spinal column; contains nerve roots that are vulnerable to injury or disease; has an inherently poor biomechanical structure. Often due to a musculoskeletal problem.

Q

Diagnostic test:

A
  • No routine labs
  • X-rays may be ordered
  • CT and MRI are performed on patients that are having surgery
  • Myelograms: radiography of the spinal cord associated nerves after intrathecal injection of a radiopaque dye: water soluble contrast
  • water base contrast: post procedural: includes elevating head to prevent seizures and n/v
  • contrast inject in subarachnoid space to see compression on the cord or see protrusion of the disk

Collaborative care:

A

Conservative management:

  • *Goal: pain control and return to baseline functioning
  • non pharmalogical

  • pt referral
  • corsets or braces for spinal support
  • -lumbar and pelvic traction not beneficial
  • application of heat/cold
  • -heat and cold the first 48 hours
  • -heat after the first 48 hrs
  • -helps reduce pain
  • massage therapy
  • Trigger point therapy
  • Spinal manipulation
  • do not do if suspected herniated disk risk of increasing neurological deficits

Q

Acute LBP: Planning:

A
  • have satisfactory pain relief
  • avoid constipation secondary to medication and immobility
  • learn back-sparing practices
  • return to previous level of activity within prescribed restrictions
19
Q

Chronic LBP:

A

*lasts more than 3 months or is a repeated incapacitating episode. Causes include degenerative disk disease, lack of physical exercise, prior injury, obesity, structural and postural abnormalties and systemic disease

20
Q

Diagnoses: Acute LBP-

A
  • Acute pain r/t herniated nucleus pulposus, muscle spasms, and ineffective comfort measures as exhibited by verbalization of back pain on movement, guarded movements, palpable muscle spasm, decreased physical activity, rating pain as >4 on a 10-point pain scale
  • Impaired physical mobility r/t pain as exhibited by limited active joint ROM, movement restrictions, muscle spasms
21
Q

Diagnoses- Chronic LBP:

A
  • Ineffective coping r/t effects of chronic pain as exhibited by verbalization of inability to cope, irritability, tension, inability to meet role expectations, altered participation in social events, ineffective or inappropriate use of defense mechanisms
  • Ineffective therapeutic regimen management r/t lack of knowledge regarding posture, exercises, body mechanics, and weight reduction as exhibited by lack of necessary knowledge to participate in treatment plan, inadequate understanding, or inaccurate follow-through of previous instructions
22
Q

Pain felt in your lower back may come from:

A

the spine, muscles, nerves or other structures in that region of you back. It may also radiate from other areas like your mid or upper back, a hernia in the groin, or a problem in the testicles or ovaries. You may feel a variety of symptoms if you hurt your back. You may have a tingling or burning sensation a dull aching or sharp pain. You also may experience weakness in your legs or feet. It wont necessarily be one event that actually causes your pain. You may have been doing things improperly–like standing, sitting, or lifting–for a long time. Then suddenly, one simple movement, like reaching for something in the shower or bending from your waist, leads to the feeling of pain.

23
Q

Pathophysiology: degenerative disc disease

A
  • As a result of biochemical changes in the intervertebral disc
  • The intervertebral disk between L4-5 vertebrae is subjected to tremendous forces and degenerative disease
  • When ligaments which surrounds the disk are injured or weakened disk material begins to extrude through the ligaments.
  • The exudated nucleus pulpous compress the spinal roots or spinal cord
24
Q

Herniated disk: risk factors

A
  • lack of muscle tone
  • excess body weight
  • poor posture
  • cigarette smoking
  • stress
  • lifting, vibration and prolonged periods of sitting
  • Occupational hazards
  • osteoporosis
  • hyperthyroidism
25
Q

Herniated Intervertebral Disk: Etiology:

A

-natural degeneration with age or repeated stress and trauma to the spine

26
Q

Herniated Intervertebral Disk: Clinical manifestations

A

-low back pain, radiating down the buttock and below the knee along the distribution of the sciatic nerve (radiculopathy)

27
Q

Herniated Intervertebral Disk: Diagnostic

A

*disc problem exists therefore more test than just x-rays are needed, myelogram; MRI, CT; possibly epidural venogram or diskogram; EMG of extremities

28
Q

Herniated Intervertebral: Conservative treatment

A
  • Restricted activity
  • Medication
  • analgesics
  • nonsteroidal antiinflammatory drugs
  • muscle relaxants
  • Local ice or heat
  • Physical therapy
  • Surgical treatment- laminectomy with or without spinal fusion
  • diskectomy
  • percutaneous laser diskectomy
  • spinal fusion with or without instrumentation
29
Q

Slipped disc:

A

When the soft, gelatinous central portion of an intervertebral disk is forced through a weakened part of a disk it is a conditon known as a slipped disk. Most herniation takes place in the lumbar area of the spine, and it is one of the most common causes of LBP. The mainstay of treatment for herniated disks is an initial period of rest with pain and anti-inflammatory medications followed by physical therapy. If pain and symptoms persist, surgery to remove the herniated portion of the intervertebral disk is recommended

30
Q

Nursing management: Spinal Surgery:

A
  • Focus on maintaining proper alignment of the spine at all times until healing has occurred.
  • flat bedrest with logrolling
  • Positioning
  • Pain management
  • Peripheral neurological assessment
  • Bowel/bladder function
31
Q

Surgical Management:

A
  • Laminectomy
  • Discetomy
  • Spinal fusion
  • Decompression
  • Microdisectomy
32
Q

Laminectomy

A

Removal of the lamina: posterior arch of the vertebra

33
Q

Discetomy

A

removal of all or part of a herniated intervertebral disc

34
Q

Spinal fusion

A

*Stabilization of 2 or more vertebrae by insertion of bone grafts with or without hardware

35
Q

Decompression

A

Release of pressure impinging on the spinal nerve or cord

36
Q

Microdisectomy

A

Smaller surgical incision; removal of the disc

37
Q

Decompression Laminectomy anterior cervical approach: PC

A

Airway obstruction r/t post-operative edema

38
Q

Decompression Laminectomy anterior cervical approach: Assessment

A
  • neurovascular will be upper extremities not lower
  • pain neck to arms
  • strength and movement of arms need to be assessed
  • vascular check: upper arms
39
Q

Decompression Laminectomy anterior cervical approach: Equipment

A

*at bedside: airway and suction

40
Q

C6-7 cervical disk laminectomy-

A

2 nurses are needed in assisting pt getting up the first day

  • prior to getting up- apply cervical collar
  • prevent twisting or pulling on the shoulders
41
Q

To maintain independence for C4 laminectomies with fusion

A

*use assistive or adaptive devices at home

42
Q

Posterior Laminectomy: Nursing diagnoses:

A
  • Risk for peripheral neurovascular compromise of blood vessels and nerves d/t the edema and pressure on the spinal nerve root and or spinal cord
  • log roll: prevents disruption of spinal alignment and integrity
43
Q

Posterior Laminectomy: When doing your assessment:

A

Pt c/o numbness

-check previous assessment
