Orthopedic Considerations
Question | Answer |
---|---|
Most common postural change with age | "senile posture" Forward Head Posture (FHP) Rounded shoulders Increased thoracic kyphosis Decreased lumbar lordosis Flexed hips and knees |
When is the greatest amount of bone density lost with osteoporosis? | Within the first 5 years of menopause |
What is estrogen's effect on osteo cells? | Reduces the lifespan of osteoclasts Lengthens the lifespan of osteoblasts |
What is secondary osteoporosis? | Bone loss associated with chronic medical conditions, nutritional deficiencies, and medications |
What modifiable risk factor doubles the risk of an osteoporotic fracture? | Smoking |
What chronic medical problems can cause osteoporosis? | RA Diabetes Hyperthyroidism Addison's Liver disease |
What kyphotic deformity is associated with osteoporosis? | Anterior compression wedge fractures of the vertebral bodies. Multiple fractures form a curve known as a "Gibbus" or "Dowager's hump" |
Signs and symptoms of a wedge fracture | Loss of height Distended abdomen Stooped posture Only 1 out of 4 women with VCF have symptoms |
Drug therapy to treat osteoporosis | Hormone replacement therapy Bisphosphonates decrease osteoclast activity Selective estrogen receptor modulators (SERMs) |
Recommended doses of Calcium and Vitamin D | Ca = 1000-1500 mg Vitamin D = 400-600 IU per day Vitamin D slows down bone loss, increases absorption of Ca in the GI, and boosts mineralization |
Medical interventions for vertebral fractures | Vertbroplasty - cement injected into the vertebral body Kyphoplasty - balloon tamp inserted prior to injecting cement Significant relief in pain in 90-95% of pts |
Interventions for kyphotic posturing | Proprioceptive and neuromuscular reeducation Kyphothosis or Spino-Medbrace Resistive exercises |
Kyphotic posture has been linked to a propensity to __________ in osteoporotic individuals. | fall |
During the acute phase of vertebral fracture PT should focus on | Exercises to reduce muscle guarding around fx site Deep relaxed breathing to decrease muscle guarding |
How long does it take for changes in BMD to appear due to exercise? | Measurable changes may only be apparent years later |
Type of exercises to increase BMD | Site-specific Heavy loading with few repetitions and high strain |
Flexion vs Extension exercises | 89% of flex group experienced VCF 67% in non-exercise group 53% in flex and ext group 16% in ext group |
T-Score for osteopenia | -1.0 - -2.5 osteopenia lower than -2.5 osteoporosis |
Osteomalacia | Bone disorder caused by a failure of normal calcification of bone matrix Softening of bones due to lack of vitamin D Dysfunction with the ability to metabolize vitamin D |
Most common cause of osteomalacia in older adults | Inadequate intake of vitamin D Lack of exposure to sunlight GI malabsorption Extensive burns Chronic diarrhea Medications - i.e. Dilantin |
Paget's disease (Osteitis Deformans) | Progression of 3 distinct stages 1) Osteoclastic 2) Osteoblastic 3) Sclerotic Osteoblast construct abnormally large and deformed bone |
Locations most often affected by Paget's disease | Pelvis Long bones Spine Reibs Sternum Cranium |
Symptoms of Paget's Disease | Most patients have no symptoms Insidious onset and slow progression Bone and joint pain or stiffness Bowing of femur and tibia and thoracic kyphosis Enlarged head Waddling gait pattern Acute px may indicate fx |
Avascular Necrosis (AVN, Osteonecrosis) | Lack of blood supply resulting in death of bone tissue in absense of infection |
Joints most likely to be affected by AVN | Hip* - most common Shoulder Knee Hand Foot Ankles |
AVN is associated with | Long-term corticosteriod use Excessive alcohol intake DM Obesity Gout Cushing's disease |
Most common locations of OA | CMC Knees Hips |
3 Stages of RA | 1) Synovium swelling, stiffness, erythema, joint effusion 2) Rapid division and growth of cells, thickening of synovium 3) Release of enzymes from inflamed cells, development of vascular granulation tissue (pannus) |
PT interventions for RA | Joint protection techniques Passive mobilization Postural exercises Strengthening exercises at all stages of RA |
Cervical RA symptom location | Usually posterior and mid-cervical |
Cervical spondylosis | Degernerative changes in cervical spine Loss of disk height Reduction in spinal ROM Radiculitis in UE (25% of patients) |
Vertebral artery syndrome (VAS) signs and symptoms | Signs induced by head rotation compressing posterior inferior cerebellar artery Vertigo Dizziness Tinnitus Blurred Vision Nausea Nystagmus Ataxia |
Possible causes of VAS | osteophytes from OA disc degeneration and narrowing of intervertebral space FHP |
Ossification of PLL symptoms | Limits cervical flex May cause radiculopathy |
PT treatments for ossification of PLL | MHP Cervical traction Avoidance of sedentary activites Postural exercises Stretching ROM PREs |
Degenerative disc disease results in _______(3) | Reduces foraminal cross-section due to inward bowing of annulus and ligamentum flavum Loads placed on longitudianl ligaments and outer-most annulus that stimulates osteoblastosis Results in osteophytes or disk-osteophyte formation |
Spinal Stenosis | Initial spinal instability with aging is caused by dehydration of intervertebral disc Addition of bone occurs at periosteal surfaces resulting in osteophyte formation causing stenosis |
What is the most common cause of neurologic leg pain in older adults? | Stenosis |
What leads to compression of the neural elements in the lumbar spine? | Posterior osteophytosis Severe disk narrowing bulging of annulus fibrosis and ligamentum flavum |
What are the most common causes of pain in active geriatric populations? | Impingement syndrome Rotator cuff pathology |
Tendonitis | Inflammation of the tendon sheath (not the tendon itself) |
Bursitis | Inflammation of the subacromial bursa |
Tendonosis | Intra-tendonous disease, such as intra-substance degeneration or tearing |
OA of the shoulder occurs more commonly than shoulder bursitis in the older population. T/F | False. Bursitis is more common than OA |
Symptoms of bursitis | Palpable tenderness in the area of the inflamed bursa Pain with movement of muscle affected by the bursa Symptom relief with rest |
PT interventions for bursitis | Avoid painful movements until pt can tolerate isometric exercise Perform exercises above and below painful arc Modalities for pain |
Rotator cuff tears are often atraumatic in older adults. T/F | True |
In the case of a RTC tear with no substantial weakness or functional disability what is recommended? | PT and anti-inflammatory medication for 6 weeks to 3 months |
Capsular pattern for the shoulder | ER is most limited, ABD, FLEX, IR limited |
Reverse TSA are indicated for | Complete RTC tear Previous TSA that failed |
Colle's Fracture | Distal radius fx with dorsal and radial displacement of the wrist and hand "Dinner fork" deformity |
OA is common in what joints of the hand? | IP and CMC joints of the thumb |
Dupuyten's contracture (definition, age of onset) | Longitudianl bands of palmar aponeurosis undergo fibrosis, MCP and PIP joints flexed Average age of onset 60 y.o. |
