Ungawalungisa Kanjani Ama-Distal Humerus Fractures Usebenzisa Amapuleti?

Ukuhlukana okushintshile kwe-distal humerus kubantu abadala kuyinkinga enzima ngenxa ye-anatomy eyinkimbinkimbi ye-elbow joint, izingcezu ezincane zokuphuka, kanye nenani elilinganiselwe lethambo le-subchondral. Amakholomu asemaceleni namaphakathi we-distal humerus akha uhlaka lukanxantathu oluzinzile. Lolu hlaka oluzinzile lukanxantathu luyaphazamiseka ngemva kokuphuka kwe-distal humerus, ikakhulukazi ukuphuka kohlobo lwe-AO C oluyinkimbinkimbi.

Umsuka

Encwadini ye-AO Internal Fixation Technique eyanyatheliswa ngo-1979, ngenxa yokuqhekeka kwe-distal humerus, ithimba le-AO lancoma ukuthi amapuleti abekwe 90 ° komunye nomunye, eyodwa medial noma lateral kanye posterior eyodwa (1).

Izinyathelo zobuchwepheshe (izimiso ze-AO zokwelashwa kokuphuka)

a: Ukwakhiwa kabusha kwe-trochlear ne-capitellum.

bc: Ngemva kokunciphisa izingcezu ezintathu zamathambo aqinile, bhora intambo ye-Kirschner iye kolunye uhlangothi. Intambo ye-Kirschner ingasetshenziswa njengentambo yomhlahlandlela yesikulufu se-cannulated esingu-3.5mm, noma isikulufu singafakwa ngokuhambisana nentambo ye-Kirschner.

d: Sebenzisa i-Kirschner wire yesikhashana ukuxhuma i-articular bone fragment ku-humeral shaft

e: Ukulungisa ucezu lwe-articular ku-humerus, i-LCP ye-anatomic kufanele iqale ibekwe endaweni engemuva ye-humerus, futhi ipuleti ingafakwa ngemuva kwe-capitulum ngaphandle kwe-cartilage. I-LCP ye-anatomical ephakathi ingabekwa endaweni ephakathi ye-humerus ukuze kuthuthukiswe ukuzinza. Ngokulahleka okukhulu kwamathambo noma ukuqhutshwa kwe-metaphyseal okunzima, ukubekwa kwama-LCP amabili ku-90 ° komunye nomunye kunconywa, njengoba lokhu kulungiselelwa kunikeza ukuzinza okungcono kwe-biomechanical. Kufanele kuqashelwe ukugwema ukungena ejoyintini uma kusetshenziswa izikulufu zokusimamisa i-engeli.

Ukuqhathaniswa kwamapuleti ensimbi ahambisanayo naqondile

Ocwaningweni Lwe-Mechanics lwango-1995 Luqhathanisa Amapuleti Amabili Okwelapha I-Distal Humeral Fractures, imiphumela yokubekwa kwamapuleti ayisithupha yaqhathaniswa (A, ipuleti elingemuva elikabili; B, ipuleti elingemuva le-ulnar, i-lateral kuya ku-radial plate; C, ipuleti eliphakathi nendawo; D, i-medial kuya ku-ulnar plate, i-plateerior engemuva kwe-plateeri ye-radial kanye nemodeli ye-radial; ukuphuka; F, imodeli ye-fractures enzima kakhulu enezikulufa eziphakathi nendawo), ebonisa ukuthi ukuphuka okuningi kungelashwa ngamapuleti aphindwe kabili ezindaweni ezahlukene zokwelashwa, kodwa ngenxa yokulimala okukhulu, lolu cwaningo lwaphetha ngokuthi ukulungiswa kwepuleti ye-medial-lateral kuhlanganiswe ne-screw fixation kuthuthukisa kakhulu ukuqina namandla okugcina (3).

U-Ata C (4) et al wabonisa ukuthi ipuleti elime mpo elinepuleti le-posterolateral kanye nezikulufu ezine ezikude ezingu-2.7 mm zazinokuqina okufanayo nesistimu yepuleti elihambisanayo ekwelapheni ukuphuka kwe-intra-articular kwe-distal humerus. Ukungakhululeki kwesiguli ngenxa yokucasuka kwesikhumba sepuleti ye-lateral, ikakhulukazi iziguli ezincane nezikhulile, zingaqedwa ngepuleti ye-posterolateral.
