Example of contracture
Trigger finger
Breaks down and gets smaller
Overstretched muscle
Tendon or ligament pulled from insertion sight
3 Most common complications in orthropedic surgery
Immobilization, Osteomyelitis, Constant chronic pain
Types of bone / tissue graft
Autologous, tibia, illiac crest, cadaver bone
Instruments used for fixation
Screws, pins, plates, nails, prosthetics
How many cranial bones
Number of facial bones
Number of bones in vertebral collumn
How many cervical bones
How many thoracic
How many lumbar
How many pair of ribs
Smooth layer of cartilage covering bone ends and providing smooth gliding surface where they meet
Articular hyaline cartilage
Pockets of fatty tissue that buffer the joint
Fat pads
Lining of joint capsule. Lubricates joint by secreting synovial fluid, which acts as a shock absorber
Synovial membrane & fluid
Point of contact or connection between bones
List pathology that leads to orthropedic surgery
Congenital, aquired disease, strain, damaged or dislocated joints, fracture, fragmentation
Generally a benign tumor that normally appears in the spur of the long bone
Benign tumor of bone
Tumor composed of fibrous or fully developed connective tissue
Malignant tumor of the bone
Cancer in the bone marrow plasma cells
Tumors in the hyaline cartilage, most often malignant
Connects degenerative contracture and atrophy of a muscle resulting from long continued interference with normal circulation
Volkmann's contracture
Break in the bone; loss of continuity of bone
Torn support structures such as ligaments and tendons or misalignment of the bone at the joint
Damaged or dislocated joints
Fracture where bone fragments do not protrude through adjacent tissue to puncture skin, though the bone may or may not be displaced
Closed / simple fracture
Bone fragments protrude through adjacent tissues and skin, creating a grave danger of infection, not only to tissue, but to the bone itself
Open / compound fracture
Fracture continues all the way through bone, versus one that extends through part of the bone
Complete or incomplete fracture
Bone is broken in several different places
Multiple fracture
Crushing or shattering of bone that dispurses bone throughout injured area
Type of fracture viewed as medical emergency due to increased risk of infection
Open fracture
Bone is crushed
Bone splinters or breaks into more that two pieces, resulting in multiple intersecting breaks and bone fragments
Bone is forced inward; generally on ingress to skull
Bone partially bent or broken; commonly found in children whose bones have not completely calcified
Portion of bone tramatically driven into another bone fragment or adjacent bone and relatively fixed in that position
Fracture line runs along length of bone
Longitudinal (linear)
Fracture line lies at an angle to the long axis of the bone
Fracture line forms a spiral pattern around the bone
Fracture line lies perpendicular to the long axis of the bone
List stages of osteogenesis
Hemorrhage, granulation, bony callus formation, consolidation and remodeling
Bone growth can be stimulated by ???
Minute electrical impulses
Occurs when fracture is healing but not completely united as expected within usual timeframe
Delayed union of bone
Occurs with fracture healing, but bone is not in proper alignment
