I.He aha ngā raruraru o te herenga o te maikuku o te femur?
He rerekē te pūnaha whao raka-maha-ahu o te humerus i te pūnaha whao raka-roto-o-te-humerus e raka-ana.
Ko te pūnaha whao honohono-roto-medullary o te humerus he mea hanga mai i te whao honohono-humeral, te mata hurihuri o te humerus, te tīwiri raka, te whao me te taupoki me te taupoki pito roa. Ahakoa ko te pūnaha whao honohono-humerus - te raka maha-ahu he mea hanga mai i te pūnaha whao honohono-humeral - te raka maha-ahu (momo maui me te matau),Φ4.5 tīwiri maukati maha-ahu,ΦHe tīwiri maukati 3.5, he taupoki pito me te taupoki pito roa.
He aha te take o tēnei rerekētanga i waenganui ipūnaha whao honohono o te humerus - raka maha-ahumete pūnaha whao o roto o te humerus e raka tahi ana?
Ka taea e te hoahoa raka maha-ahu te raka i te wāhi whati i ngā taha maha, ka whakarato i te pānga whakapiri pumau me te pono, ka whakaiti i te nekehanga moroiti o te pito whati, ka whakahaere i te whakaora whati. He pai ake mō ngā āhuatanga whati uaua. Ko te pūnaha whao intramedullary kore-maha-ahu e raka ana i te femur he pai ake mō ngā āhuatanga whati ngawari.
Tuarua.He aha ngā painga o te intramedullary nailing?
Ko te pūnaha whao honohono o te humerus - he kupu hauora matatau te raka maha-ahu mō ngā whati o te humerus. E whakaatuhia ana ōna painga i roto i ngā āhuatanga e whai ake nei:
1)He miro motuhake o roto o te tīwiri hei whakapai ake i te pumau.
2)Ka whakapiki ake te tīwiri cortical takirua i te pumau o ngā whati whakawhiti me ngā whati poto whakarara.
3)He mea hanga mai i te whao poto me te whao roa, ā, he maha ngā momo tīwiri hei whiriwhiri māu hei whakaoti i ngā whati ngāwari me ngā whati uaua o te humerus proximal me te tuaka humerus. He rite ki te kakau wheua, he hoahoa hihiri ka taea te whakahaere, he nekehanga moroiti, ka whakatairanga i te hononga.
4)Mā te whakamahi i ngā tikanga tino iti te whakaekenga, ka iti noa te tapahi o te pokanga, ka whakaiti i te kino ki ngā kiko ngohengohe e karapoti ana, ka whakaiti hoki i te mōrearea o te mate me ngā raruraru i muri i te pokanga.
5)He pai te pumau o te tuaka me te hurihuri, ka taea te tu atu i te kawenga tinana nui, ā, he pai hoki mō te mahi wawe o ngā tūroro.
III.Āhea me tīmata te maimoatanga i muri i te whati o te humerus?
Te maimoatanga pokanga：
1) Te whao i roto i te hononga o te waewae: Koinei te maimoatanga pai rawa atu mō ngā whati o te kakau femur, inā koa mō ngā tūroro taitamariki me ngā tūroro hohe.
2)Te whakapiri pereti: Mō ētahi whati uaua, mō ngā tūroro rānei kāore e tika ana mō te whakapiri whao intramedullary, ka taea te whiriwhiri i te whakapiri pereti.
3)Kaiwhakatikatika o waho: Ka whakamahia whānuitia mō ngā whati tuwhera, ngā tūroro he maha ngā whara, me te hunga rānei e hiahia ana kia whakatikatikahia mō te wā poto.
4）Te pokanga wheua: Mō ngā whati o te huha tata, inā koa ngā whati o te kaki o te huha, ngā whati rānei o raro i te tumuaki o te upoko i roto i ngā tūroro kaumātua, e tika ana pea te pokanga wheua hope.
Maimoatanga kore-pokanga：
1）Te rongoā kukume: He pai mō ētahi tūroro kāore e tika ana mō te pokanga, pērā i te kaumātua, te hunga ngoikore te āhua tinana, te hunga rānei he mate kino ā-roto.
2）Te whakapiri i te pāreti, te whakapiri rānei i te whāriki: Mō ētahi whati femur ngāwari, kāore hoki i te nekehia, ka taea te whakamahi i te whakapiri pāreti, te whakapiri rānei i te whāriki.
