Study Notes
Musculos del Dorso
- Le musculos del dorso pote esser classificate in duo gruppos: musculos extrinsic e musculos intrinsic.
- Le musculos extrinsic son superficiale e agisce super le bracio e le scapula, le musculos intrinsic son plus profunde e agisce super le columna vertebral.
Musculos Extrinsic del Dorso
- Le musculos extrinsic del dorso pote esser dividite in duo stratas: le strato superficial e le strato intermedie.
- Le strato superficial include le musculos trapezius, latissimus dorsi, levator scapulae, e rhomboideus.
- Le strato intermedie include le musculos serratus posterior superior e serratus posterior inferior.
Musculos Intrinsic del Dorso
- Le musculos intrinsic del dorso pote esser dividite in tres stratas: le strato superficial, le strato intermedie e le strato profonde.
- Le strato superficial include le musculos splenius cervicis e splenius capitis.
- Le strato intermedie include le musculos iliocostalis, longissimus e spinalis.
- Le strato profonde include le musculos semispinalis, multifidus, rotatores, interspinales, intertransversarii e levatores costarum.
Ossea del Membro Superior
- Le cintura scapular include le clavicula e le scapula.
- Le clavicula connecte le membro superior al trunco.
- Le scapula es un osse triangular que se situa super le 2° a 7° costulas.
- Le bracio contine le humero.
- Le antebracio contine le radio e le ulna.
- Le mano contine le osses carpales, metacarpes e phalanges.
Ossea del Mano
- Le mano contine 8 osses carpales: scaphoide, lunate, triquetrum, pisiforme, trapezium, trapezoid, capitate e hamate.
- Le osses metacarpes son 5 osses que forman le palma del mano.
- Le phalanges son 14 osses que forma le digitos.
Fracturas del Humero
- Fracturas del humero pote esser asociate con injurias a nervos e arterias:
- Colli chirurgico: nervo axillari.
- Sulco radial: nervo radial.
- Extremo distal del humero: nervo mediano e arteria brachial.
- Epicondylo medial: nervo ulnar.
Fracturas del Radio
- Un fractura transversal complete del ultime 2 cm del radio, appellate fractura de Colles, es le fractura le plus commun del antebracio.
- Le fragmento distal es displaciate dorsalmente.
- Le fractura resulta de un extension forciate del mano, usualmente como resultato de un tentativa de amollecer un caduta per extender le membro superior.
Clavicle
- The clavicle (collar bone) connects the upper limb to the trunk.
- The medial two thirds of the clavicle's shaft are convex anteriorly, while the lateral third is flattened and concave anteriorly.
- The clavicle has a sternal end (flat) which forms the sternoclavicular joint, and an acromial end (round) which forms the coracoacromial joint.
Scapula
- The scapula (shoulder blade) is a triangular flat bone that overlies the 2nd–7th ribs.
Digits
- The digits (fingers) have three phalanges except for the first (the thumb), which has only two.
- Each phalanx has a base proximally, a shaft (body), and a head distally, the shafts of the phalanges taper distally.
Carpals
- The carpals are the eight small bones of the wrist.
- The carpals include the scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate.
Humerus
- In fractures of the humerus the following elements can be injured:
- Surgical neck: axillary nerve
- Radial groove: radial nerve
- Distal end of humerus: median nerve and brachial artery
- Medial epicondyle: ulnar nerve
Radius
- A complete transverse fracture of the distal 2 cm of the radius, called a Colles fracture, is the most common fracture of the forearm.
- The distal fragment is displaced dorsally.
- The fracture results from forced extension of the hand, usually as the result of trying to ease a fall by outstretching the upper limb.
