Advanced Health Assessment • Heather Hull, ARNP, PNP
Primary Functions • Provides structure for soft tissues • Protects vital organs • Storage place for minerals • Produces blood cells • Provides stability & mobility for physical activity
Development of M-S System • Fetal: Cartilage calcifies & becomes bone • Childhood: Bone increases in length via epiphyses • Increase in diameter • New bone tissue around bone shaft • Ligaments stronger than bone until puberty
Development of M-S System • Bone growth completed about age 20 • Peak bone mass around age 35 • Aging results in Fibrosis of connective tissue with aging: • Increased collagen • Decreased water content
Aging • Tendons become less elastic • Decreased reaction time & ROM • Increased bone resorption • Decreased bone density • Deterioration of cartilage around joints
Common M-S Problems • Systemic • RA, Lupus & Polymyositis • Local • Lumbar strain • Tennis elbow
Facts • 1 of 7 persons suffer from some type of M-S disorder • Cost 60 billion annually • Ranks second for reasons for visits to medical office
Structure • Bone • Bursae • Muscles • Ligaments • Tendons • Cartilege • Joints
Anatomical References • Medial: ulnar & tibial • Lateral: radial & fibular • Joint Motion:Shoulder • abduction - adduction • flexion - extension • internal & external rotation
History Questions • Employment, Exercise,Weight, Nutrition, Cigarette use, Medications • PMH: Trauma to nerves or soft tissues, fractures, viral illness, chronic illness, breast implants • FH: Congenital deformities, scoliosis, back problems, arthritis
Common Symptoms • Pain • Weakness • Deformity • Limitation of movement • Stiffness • Joint clicking
Assessment • Inspection • Palpation • Passive & Active ROM • Muscle Strength • Integrated Function • Gait • Spine
Joint Pain • Inflammation Present: • Yes: RA, SLE • No: Osteoarthritis • Number of Joints Involved: • Monoarticular - Gout, Trauma, Septic Arthritis, Lyme Disease • Polyarticular - RA, SLE
Joint Pain: Site of Involvement • Distal phalangeal - Osteoarthritis • Metacarpal phalangeal, wrists - RA, SLE • First metatarsal phalangeal - Gout, Osteoarthritis
Osteoarthritis • Affects 1/4 or population • Degeneration of articular cartilage • Weightbearing & distal finger joints • Pain worsens with exercise • Morning stiffness or immobility • Heberdon’s nodes
Rheumatoid Arthritis • Chronic inflammatory condition • Insidious onset over weeks to months • Fatigue, malaise, morning stiffness • Swelling of joints, polyarticular, PIP, MCP joints commonly affected, symmetrical movement • ROM may be limited, tenderness of joints • Lab: RF, Low H&H, ANA
Low Back Pain • Disables 5.4 million Americans • Lifetime prevalence 60-90%
Risk Facators • Repetative Lifting • Exposure to vibration • Cigarette Smoking • Osteoporosis - Spinal Stenosis • Obesity • Lack of Exercise • Increased Age
Differential Diagnosis • Acute lumbar-sacral sprain • Postural backache • Lumbar disk syndrome • Osteoarthritis • Irritable bowel syndrome
Differential Diagnosis • Urinary Disorders • Gynecological disorders • Ankylosing spondylitis • Tumors
Examination • Inspection • Palpation • Passive & Active ROM • Flexion • Extension • Lateral • Rotation
Examination • Heel - Toe Walking • Deep tendon reflexes • Motor strength • Sensation • Distracted SLR
Examination • In Supine position • SLR • Hip - ROM • Sacroiliac joints • Hip abduction
Lumbar Disc Syndrome • With repetative trauma: progressive degeneration of nucleus pulposus leading to protrustion or complete extrusion of portion of disc contents into neural canal. • 95% at 4 & 5 spaces • Most common between 3rd & 4th decades
Clinical Features • Low back pain • Restriction of back motion • Radicular pain • Paresthesias • Local tenderness
Acute Lumbar-Sacral Strain • Related to muscular, ligaments, or facial strain secondary to specific trauma or continuous mechanical stress • Most common in age 20 - 40 • Obesity & lack of exercise
Clinical Features • Low back pain • Muscle spasm • Local tenderness or swelling • Neurologic exam negative
Treatment • Bedrest • Ice - 24 hours • Heat - dry or moist • NSAIDS • Low back exercises • May need to add a muscle relaxant
Cauda Equina • Massive midline protrusion • Medical emergency • Presentation: weakness to legs, urinary changes, impotence, loss of sphincter tone & saddle anesthesia
Knee • Largest joint in body • No intrinsic stability, depends on ligaments, muscles, menisci & capsule for support
Knee • Medial collateral ligament • Lateral collateral ligament • Anterior cruciate ligament • Posterior cruciate ligament • Quadriceps • Hamstrings • Meniscus
Knee Pain - History • Position of leg at time of injury • Popping? • Slepping out of joint? • Swelling? • Stiffness? • Loss of function?
Examination • Inspection • Palpation • ROM • Stability Testing
Examination • Lachman • Posterior drawer • Valgus & varus stress • McMurry
Examination • Apley compression • Compression • Shrug • Apprehension
Injuries to Meniscus • Normal rotation of tibia is forcibly prevented as knee is flexed or extended • Simple twisting injury to knee can tear meniscus • Medial meniscus injuries 10 X more common that lateral meniscus injuries
Clinical Features • Knee pain - well localized • Swelling - gradual • Locking of knee • Popping or tearing
Clinical Features • Walking up & down stairs difficult • Joint effusion • Limited ROM • Positive McMurray • Normal X-ray
Treatment • Rest • Immobilization of knee • Ice • Elevation • ROM - quadriceps strengthening exercises • NSAIDS • Possible surgery
Lesions of Ligaments • Forceful stress against knee - abduction • Ability to bear weight is lost • Immediate swelling • Popping or tearing • Positive Lachman or Posterior Drawer
Treatment: Grade I or II • Protection • Rest • Ice • Compression • Elevation • Support • NSAIDS
Treatment: Grade III • Orthopedic Consultation
Anterior Knee Pain • Seen in adolescents and young adults • Athletes • Irregular pattern of movement of patella • Over-use type of syndrome
Clinical Features • Pain beneath or near patella • Aggravated by walking up & down stairs, squatting or prolonged sitting • No pain during activity - pain follows activity • Crepitus • Swelling • Positive compression, shrug and/or apprehension tests
Treatment • R • I • C • E • NSAIDS
Osgood - Schlatter Disease • Involves the growing tibial tuberosity • Adolescents, 8 - 15 years • Bilateral • Males > Females • Self-limited
Clinical Features • Local pain & swelling over tibial tuberosity • Pain with stair walking, exercise, squatting on kneww • Lateral x-ray may reveal variable degrees of separation & fragmentation of tibial epiphysis
Treatment • Remove stress on tendon • Abstinence from physical activity
Carpal Tunnel Syndrome • Compression of medial nerve of wrist • Associated with • Hypothyroidism • Gouty Arthritis • Decreased B6
