Ko te whati o te kōiwi tetahi o ngā whati tino noa, e 2.6%-4% o ngā whati katoa. Nā ngā āhuatanga hanganga o te waenganui o te kōiwi, he nui ake te kitea o ngā whati o te waenganui o te kōiwi, e 69% o ngā whati o te kōiwi, ko ngā whati o ngā pito taha me waenga o te kōiwi e 28% me te 3% ia.
He momo whati tino onge tēnei, he rerekē ki ngā whati o te angaanga waenga e puta mai ana i te whara tika o te pakihiwi, i te kaha rānei e tukuna ana mai i ngā whara e amo ana i te taumaha o te peka o runga, he maha ngā whara e pā ana ki ngā whati o te pito waenga o te angaanga. I ngā wā o mua, ko te huarahi maimoatanga mō ngā whati o te pito waenga o te angaanga he tikanga tiaki noa iho. Heoi, kua whakaatuhia e ngā rangahau 14% o ngā tūroro he whati kua nekehia te pito waenga ka pāngia e te kore hononga. Nō reira, i ngā tau tata nei, he maha ake ngā tohunga kua tahuri ki te maimoatanga pokanga mō ngā whati kua nekehia te pito waenga e pā ana ki te hononga sternoclavicular. Heoi, he iti noa iho ngā kongakonga o te angaanga waenga, ā, he herenga ki te whakapiri mā te whakamahi i ngā pereti me ngā tīwiri. He take wero tonu te kukū ahotea ā-rohe mō ngā taote pokanga wheua e pā ana ki te whakaū i te whati me te karo i te korenga o te whakapiri.
I. Hurihanga LCP o te Clavicle Distal
He rite tonu ngā hanganga tinana o te pito tawhiti o te angaanga ki te pito tata, he whānui te turanga o ia mea. He maha ngā kōhao tīwiri maukati o te pito tawhiti o te pereti kōpeketanga maukati angaanga (LCP), e āhei ai te whakapiri pai i te kongakonga tawhiti.
I runga i te āhua ōrite o te hanganga i waenganui i ngā mea e rua, kua whakatakotoria e ētahi tohunga he pereti maitai whakapae ki te koki 180° i te pito tawhiti o te wheua wheua. Kua whakapotohia hoki e rātou te wāhanga i whakamahia tuatahitia hei whakau i te pito tawhiti o te wheua wheua wheua, ā, kua kitea he pai te uru o te whakaurunga o roto, kāore e hiahiatia he hanga.
Kua kitea te pai o te taunga o te pito tawhiti o te wheua ki te tūranga whakahurihia, me te whakamau ki te pereti wheua i te taha waenga.
I roto i tētahi take o tētahi tūroro tāne 40-tau te pakeke me te whati i te pito waenga o te anga matau, i whakamahia he pereti maitai anga distal kua hurihia. I whakaatuhia i roto i tētahi whakamātautau whai muri i ngā marama 12 i muri i te pokanga he pai te putanga whakaora.
Ko te pereti kōpeketanga maukati anga whakamuri (LCP) he tikanga whakapiri ā-roto e whakamahia whānuitia ana i roto i te mahi haumanu. Ko te painga o tēnei tikanga ko te pupuri i te kongakonga wheua waenga e ngā tīwiri maha, e whakarato ana i te whakapiringa mau. Heoi, me whai kongakonga wheua waenga nui tēnei tikanga whakapiri kia pai ai ngā hua. Mena he iti te kongakonga wheua, he komihana rānei i roto i te hononga, ka ngoikore pea te whai huatanga o te whakapiringa.
II. Tikanga Whakapūmau Poutū Pereti Takirua
Ko te tikanga pereti takirua he tikanga e whakamahia whānuitia ana mō ngā whati pakaru matatini, pērā i ngā whati o te humerus distal, ngā whati pakaru o te radius me te ulna, me ētahi atu. Ina kore e taea te whakatutuki i te whakapiringa whai hua i roto i te papa kotahi, ka whakamahia ngā pereti maitai raka takirua mō te whakapiringa poutū, ka hangaia he hanganga pumau papa rua. I roto i te koiora-mīhini, ka tukuna e te whakapiringa pereti takirua ngā painga ā-mīhini ki te whakapiringa pereti kotahi.
