What is Osteoarthritis
The wearing away of hyaline cartilage in bone
What are the symptoms of osteoarthritis?
pain, stiffness, prominent morning pain, localized tenderness, cracking, crepidus.
What is the primary treatment for osteoarthritis?
manage symptoms and correct poor mechanics
What is a Bursa?
a fluid filled sac that's primary function is to reduce friction
What causes Bursitis?
sudden irritation can cause acute bursitis, while overuse and constant external compression can cause chronic bursitis.
Signs and Symptoms of Bursitis
Pain, swelling, and some loss of function
The Result of repeated joint trauma
develops from an improperly treated injury
What is Chronic Synovitis?
thickening of the synovial lining and compromises joint mechanics and ROM
Functions of Bone
Body support, organ protection, movement via lever systems, calcium storage
Ribs, Skull, and Scap
Vertebrae and Skull
Wrist and Ankle
humerus, ulna, radius, fib, tib, femur
What is the Most commonly Injured Bone type?
Shaft - hollow and cylindrical covered by compact bone, medullary cavity contains yellow marrow lined by endosteum
Ossification occurs from synthesis of bones and matrix from what two cells?
Osteoblasts & osteoclasts
composed of cacellous bone and has hyaline cartilage covering. PROVIDES ATTACHMENT AREA FOR MUSCLE
Dense, white, fibrous covering which penetrates bone via sharpey's fibers. contains blood vessels and oseoblasts
How does the diameter of bone increase?
Osteoblasts add bone to the exterior while clasts break down the medullary cavity
every change in form and function or in its function alone is followed by changes in architectural design.
Displacement of the fractured ends breaking through the surrounding tissue
little movement or displacement
Signs & Symptoms of a fracture
Deformity, pain, point tender, swelling, pain on active and passive motion
Direct or indirect, sudden, violent, and forceful muscle contraction or force must occur.
What is a greenstick fracture?
when a bone bends and cracks, instead of breaking completely into separate pieces.. Most common in children
What is a Comminuted Fracture?
A Fracture in which bone is splintered, broken, or crushed into a number of pieces
What is a Linear Fracture?
runs parallel to the long axis of a bone
What is a Transverse Fracture?
A fracture which the line of break forms a right angle with the axis of bone
