Mallet Finger - ANS Rupture of the extensor at its insertion Jersey Finger - ANS Rupture of flexor digitorum profundus (FDP) at its insertion Distal phalanx Boutonniere deformity - ANS Rupture or tear of the central portion of the extensor tendon Kienbock's disease - ANS avascular necrosis of the lunate Where is the cuboid located? - ANS lateral aspect of foot Where is the Capitellum located? - ANS Is lateral and it articulates with the radial head of the radius. symptoms of carpal tunnel syndrome - ANS numbness, pain, tingling in the thumb, index, and middle fingers. Median nerve distribution - ANS Carpal tunnel syndrome Bennets Fracture - ANS fracture at the base of the first metacarpal (Thumb) De Quervain's Tenosynovitis - ANS inflammation the extensor pollicis brevis and the abductor pollicis longus tendons on the side of the wrist at the base of the thumb. Can be brought on by simple strain injury, treated by bracing the thumb and wrist. gameskeeper's thumb - ANS aka skiers thumb injury to the ulnar collateral ligament ganglion cyst - ANS Mass on a finger that contains jelly-like viscous fluid and is connected to a synovial Sheath or capsule Giant cell tumor - ANS a rare, aggressive non-cancerous tumor. Usually develops near a joint at the end of the bone.Giant cell tumors most often occur in young adults . The exact cause of giant cell tumors remains unknown. lipoma - ANS Benign tumors of fat, formed between the skin and the underlying muscle Enchondroma - ANS Benign tumor consisting of cartilage in bone sugar tong splint - ANS TX: temp immobilize wrist, forearm fx's Prevents suppinating and pronating. Thumb Spica Splint - ANS Immobilization for acute non-displaced scaphoid Fracture thumb spica cast - ANS TX: stable, reduced fx's, thumb ligament injuries, non-displaced scaphoid fx's Physis - ANS cartilaginous area between the epiphysis and metaphysis responsible for longitudinal growth of bones. Diaphysis - ANS shaft of long bone (compact bone) Epiphysis - ANS End of a long bone. After growth stops, it becomes part of the metaphysis What is the physis also Known as? - ANS Growth Plate metaphysis - ANS growth zone between the epiphysis and the diaphysis during development of a long bone. Composed of primary and secondary spongiosa. Primary spongiosa - ANS The region of the ossification center containing calcified cartilage, woven bone and lamellar bone Secondary spongiosa - ANS Part of the ossification center consisting of spicules of lamellar bone Bursae - ANS fluid-filled sac that allows for easy movement of one part of a joint over another. They relieve pressure between two moving parts. Fascia - ANS Sheets of dense connective tissue that envelop muscular components and hold Muscles, blood vessels and nerves into bundles Synovium - ANS Connective membrane that lines joints and produces and absorbs synovial fluid. This lubricates and feeds cartilage surfaces Periosteum - ANS A firm 2 layered fibrous membrane covering the surface of bones. The outer layer contains blood vessels while the inner layer contains connective tissue cells and elastic fibers. Important for bone growth and repair Colles fracture - ANS fracture of the distal radius at the wrist where the fragment is tilted dorsally Smith fracture (reverse Colles) - ANS Fracture of the distal radial head fragment displaced anterior fall backward on outstretched arm Buckle Fracture - ANS An incomplete fracture in children in which one side of the bone buckles out upon itself without disrupting the other side. Boxer's fracture - ANS Fracture of the fifth metacarpal (most common Hand Fracture) The fracture is at the base of the distal metaphysis stress fracture - ANS a slight bone break caused by repetitive low-impact forces, such as running, rather than single forceful impact impacted fracture - ANS fracture in which bone fragments are pushed into each other Butterfly fracture - ANS Usually occurs after high-energy force, causing a comminuted fracture resembling a V Shape/Butterfly transverse fracture - ANS complete fracture that is straight across the bone at right angles to the long axis of the bone chondrolysis - ANS degeneration of cartilage cells ending in cell death chondromalacia - ANS softening of cartilage on the underside of the patella chondroporosis - ANS formation of empty space in cartilage osteochondritis - ANS inflammation of the bone step through gait - ANS Injured limb is advanced then the intact limb is brought through to same position (Walking) Two-point gait - ANS (Hop to Gait) The Crutches and injured limb are advanced as one unit, then the intact limb is advanced to the crutches. Three point Gait - ANS both crutches and the affected leg are advanced together and then the normal leg is moved forward. Four Point Gait - ANS Slow pattern One crutch, Injured limb, other crutch, intact limb valpeau dressing - ANS applied to the arm and torso such that the elbow is at the side in flexion and the hand is pressed against the upper chest Munster cast - ANS AKA supracondylar cast: Limits suppination and pronation of arm w/out completely prevention flx/ext of elbow. Applied in manner of long arm cast, but cast is extended just above distal biceps. Once hardened, prox portion is trimmed around elbow jt. (supracondylar cast)
