• Bone protruding through skin
• Numbness/tingling in joint
Open/Closed FxOpen/Closed Fx

maxilla• Common in driver in MVA
– Ex: Pott fx • Distal end of fibula
• Locations– Ex: Fx of humerus

DislocationsDislocations
• S&S– Misshapen joint, extreme pain– Rapid edema, ecchymosis, immobility– Possible damage to tissues, nerves, vessels– Can result in distal paralysis, osteoarthitis
• Etiology– Trauma – Congenital weakness– Ehlers-Danlos syndrome
http://www.immediateactionservices.com/dislocatedpatella_jpg.html
Sprains and StrainsSprains and Strains• Sprain
– Acute partial tear of ligament– 1st, 2nd, 3rd degree
• Strain– Injured muscle, tendon, or other tissue– Caused by overuse, overstretching
• Etiology– Acute – Chronic overuse (cumulative trauma)
• Sports/Occupation
S&S, Sprains/StrainsS&S, Sprains/Strains
• Pain, weakness, numbness, edema
• Stiffness, tenderness, soreness– Typical of chronic overuse
• Difficulty using
• Sprains can include damage to– Blood vessels/nerves– Ecchymosis and edema
WhiplashWhiplash
• Trauma to cervical vertebrae
• Etiology– Usu. Due to MVA – Head whipped backwards– Stresses neck spine and muscles
Slipped DiscSlipped Disc
• Herniated Nucleus Pulposus– Cartilage disc ruptures/protrudes– Puts pressure on nerves– Usu. Lumbar-sacral area
• Etiologies– Cumulative trauma (body mechanics)– Impact (fall, MVA)– Poor posture/aging
http://www.nlm.nih.gov/medlineplus/ency/imagepages/9700.htm
MyelopathyMyelopathy
• “any disease or disorder of the spinal cord or bone marrow”
• Spine– Myelopathy - Often results from compression– Caused by injury/pathology– Injury = spinal cord injury

Carpal Tunnel SyndromeCarpal Tunnel Syndrome
• Entrapment/Compression of Median Nerve
http://images.medicinenet.com/images/illustrations/carpal_tunnel.jpg
Carpal Tunnel SyndromeCarpal Tunnel Syndrome
• S&S– Pain more pronounced at night– Swelling of wrist/hand, “fluttering” of fingers– Shaking/moving wrist may bring relief (temp.)
• Etiology– Tendons w/in carpal tunnel become inflamed– Due to Repetitive overuse of hand/wrist/fingers– Pinching of median nerve
• Ergonomics can help in prevention
Pathologic Bone DisordersPathologic Bone Disorders
– Fxs– Osteoarthritis– Rheumatoid arthritis– Gout– Pseudogout– Rickets/Osteomalacia– Osteoporosis– Lyme Disease– Nonunion/Malunion– Neoplasms– Marfan Syndrome
Pathologic FracturesPathologic Fractures
• Common etiologies– Neoplasms– TB of bone– Paget disease– Osteoporosis
• “Spontaneous” fxs – ALWAYS pathologic– insufficiency fx, nontraumatic fx, or nontraumatic compression fx
= pathologic fx• “Compression” fx – be careful!!!
– Can have traumatic OR pathologic etiology
Mal-union/Non-unionMal-union/Non-union
• Malunion – healed fx with poor alignment
• Non-union - failure of the fragments of a broken bone to knit together (no healing)– DM– Renal disease– Smoking slows bone healing

ArthritisArthritis• Inflammation of joints, breakdown of
cartilage (250+ types)
• S&S (common to all types)– Inflammation– Swelling– Pain– Stiffness– Mobility problems
• Can be Primary, often 2ndary
OsteoarthritisOsteoarthritis
– By far the most common type– Degenerative Joint Disease, usu. older pts
• Degenerative cartilage/hypertrophic bone
– Degenerative or hypertrophic arthritis, polyarthritis
– “Wear and Tear”- Arthritis– Joints – large, weight-bearing usually affected
• Hips, knees, spine – fingers, wrists, elbows, ankles
ArthritisArthritis
• Arthritis due to Infection– Gonococcal arthritis– Septic arthritis

http://www.healthinplainenglish.com/health/musculoskeletal/gout/gout-surgery.jpg
ArthritisArthritis
• Post-Traumatic Arthritis– “Any traumatic injury to the joint, its ligaments
or supporting muscles makes the joint unstable. The increased stress on the joint cartilage may lead to arthritis.”
– http://global.smith-nephew.com/us/patients/Posttraumatic_arthritis_11517.htm
Lyme DiseaseLyme Disease
• Infectious - spirochete bacterium– Borrelia burgdorferi, B. afzelii (Europe)– 1975, Lyme, Conn– All 50 states, 5 continents– Hikers, campers
• S&S– Red, itchy rash, red circle center (target lesion)
• 50% of patients

• Lyme arthritis can occur acutely/chronicallyhttp://www.wesleykozinn-md.medem.com/medem/photos/s1802335_p401698_Erythema%20migrans.jpg
OsteoporosisOsteoporosis• Loss of normal bone
density• Most common
metabolic bone disease
• S&S– Loss of height– Spontaneous fxs– Pain can occur, but
usually not until fx occurs
• Risk factors– Female– Postmenopausal
• Lack of estrogen
– Small-boned– Northern European/Asian
background– Smoking– Family hx– Some meds (heparin)
• Increasing #s of men
Rickets vs. OsteomalaciaRickets vs. Osteomalacia
• Soft, flexible, deformed bones• Same disorder
– Rickets is term when occurs in children
• Etiology– Lack of/ineffective use of vitamin D
• Non-exposure to sun, renal diseases, malabsorption of D
• S&S– Fatigue, stiffness– Backaches– Muscle twitching/cramps– Fxs, bowed legs, chest deformity– Shortening of spine
Bone CancerBone Cancer
• Malignant (cancerous) tumor of the bone.
• Benign (noncancerous) bone tumors are more common than malignant ones.
• Malignant tumors that begin in bone tissue = primary bone cancer.
• Primary bone cancer is far less common than cancer that spreads to the bones (2ndary).
• Cancer that spreads to the bones from other parts of the body is metastatic cancer, and is named for the organ or tissue in which it began.
• The most common cancers that spread to the bone are – Breast – Kidney – Lung – Prostate
– Thyroid

Common types of Common types of primary bone cancerprimary bone cancer
• Osteosarcoma arises from osteoid tissue– This tumor occurs most often in the knee and upper
arm • Chondrosarcoma begins in cartilaginous tissue.
– Chondrosarcoma occurs most often in the pelvis upper leg, and shoulder.
– Sometimes a chondrosarcoma has cancerous bone cells (osteosarcoma).
• The Ewing Sarcoma Family of Tumors (ESFTs), – usually occur in bone but can arise in soft tissue
(muscle, fat, fibrous tissue, blood vessels, or other supporting tissue).
– ESFTs occur mostly along the backbone and pelvis and in the legs and arms.
Marfan Syndrome Marfan Syndrome ((arachnodactyly)arachnodactyly)
• Dominant inherited disorder of connective tissue
• causes abnormalities of the eyes, cardiovascular system, and musculoskeletal system
• Named in 1896, gene id in 1991
• Dx: Four skeletal signs + at least one in another system
• Bones and Joints
• Long, thin fingers • Long arms & legs • Tall/thin body type • Curvature of spine
(scoliosis or kyphosis) • Chest sinks in (pectus
excavatum) OR• Chest sticks out/pigeon
breast (pectus carinatum) • Flexible joints • Flat feet • Teeth that are too crowded
