Mō ngā kaihoko e rapu ana i ngā MOQ iti me ngā momo hua nui, ka tukuna e Multispecialty Suppliers he whakaritenga MOQ iti, he otinga whakahaere rauemi mai i te tīmatanga ki te mutunga, me te hokohoko maha-kāwai, e tautokona ana e ō rātou wheako ahumahi me te ratonga me te māramatanga pakari ki ngā au hua hou.
Ⅰ. He aha ngā momo whati o te femur e whā?
1. Te whati o te femur proximal
Te whati o te kaki o te femur: He mea noa tēnei i roto i ngā tūroro kaumātua e pāngia ana e te osteoporosis, ā, ka tere pea te arahi ki te ischemia me te nekrosis o te pane o te femur.
Whati i waenganui i te trochanter nui me te trochanter iti: Kei waenganui i te trochanter nui me te trochanter iti te rārangi whati, he pai ake te rere o te toto, ā, he tere ake te whakaora.
Ngā whati subtrochanteric: ka puta i raro i te trochanter iti, ko te nuinga ka puta mai i ngā whara kaha nui, ā, he maha ngā wā e hiahiatia ana he maimoatanga pokanga.
2. Te whati o te kakau o te femur
Ka puta ngā whati i waenganui o te femur, ā, he maha ngā wā ka puta mai i te kaha tika (hei tauira, ngā aituā motuka, te hinganga), ā, he maha ngā wā ka haere tahi me te nekehanga nui me te kino o ngā kiko ngohengohe.
3. Te whati o te femur distal
Te whati o te femur i runga i te tūtae o te waewae: e tata ana ki te hononga turi, ka pā pea te mata o te hononga, ā, me whakaiti te hanganga tinana kia whakahokia mai ai te mahi a te hononga.
Ngā whati o te hononga femur: e pā ana ki ngā hononga femur o waho me te taha o roto, me arotake te papatahi o te hononga hei ārai i te mate rumatiki.
Ⅱ. He aha ngā mahi whakatūpato me mahi i te wā e pokangahia ana ngā whao o te femur?
I muri i te pokanga, me aro nui ki ngā āhuatanga e whai ake nei: Tuatahi, kia aro ki te turuturu o te toto i te wāhi i tapahia, me te whakamahi i ngā paturopi tika mō ngā haora 24~48 i muri i te pokanga hei ārai i te mate. Ka whakarerekētia te wāhi i tapahia i ia wā, ā, ka tangohia te wai i roto i ngā haora 24. Tuarua, me mahi ngā mahi me ngā mahi whakakori tinana i muri i te pokanga i te wā e taea ai. Ko ngā whao intramedullary mō ngā whati o te kakau femur ko ngā whao me whao mā roto i ngā hononga hope, turi rānei, ka pā kino ki ngā kiko ngohengohe huri noa i ngā hononga, ā, ka puta pea he toto i roto i ngā hononga. Nō reira, e taunakihia ana kia mahi wawe i te nekehanga hononga i muri i te pokanga hei ārai i ngā raruraru pēnei i te piri o ngā hononga, me te whakaiti hoki i te hanganga o te thrombosis uaua hohonu i ngā pito o raro. Tuatoru, kāore e tūtohutia kia kawe wawe rawa i ngā taumaha i muri i te pokanga, ā, me arotake tonu i ngā hihi-X kia mārama ai te tipu me te whakaora o te pūtake whati, me te whakatairanga i te whakaora tika o te whati mā roto i ngā rongoā.
Ⅲ. He aha te rerekētanga i waenganui i te PFN A me te A2?
He rerekē rawa ngā ariā e rua o te PFN-A me te A2, ko te mea tuatahi he taputapu whakapiri ā-roto mō te rongoā i ngā whati femur intertrochanteric (he whao intramedullary femur proximal anti-rotation), ā, ko te mea tuarua he whakarōpūtanga o ngā whati femur intertrochanteric i roto i te pūnaha momo AO.
Ko te PFN-A he taputapu whakatikatika ā-roto motuhake, arā, ko te "Proximal Femoral Nail Anti-rotation". He pūnaha whao intramedullary e whakatika ana i ngā whati mā te whakauru ki roto i te kōhao medullary femoral, me ngā āhuatanga o te anti-rotation me te pumau, ā, e whakamahia ana mō te rongoā i ngā whati intertrochanteric o te femoral femoral me ngā momo AO A1, A2, A3 me ngā whati subtrochanteric teitei.
Ko te A2 he momo whakaahuatanga o ngā whati femur intertrochanteric i roto i te pūnaha whakarōpūtanga AO, ā, e whakarōpūtia ana hei whati pumau. E ai ki te whakarōpūtanga AO, ko te momo whati A2 e tohuhia ana e te rārangi whati e haere ana i roto i te rohe trochanteric me te pakaru o te cortex medial i te iti rawa e rua ngā wāhi me te maha o ngā aukati whati. Ka wehea anō kia rua:
Momo A2.1: He puranga whati waenga kei waenganui i ngā trochanter.
Momo A2.2: He maha ngā aukati whati waenga i waenganui i ngā trochanter.
Momo A2.3: Ka toro atu te rārangi whati neke atu i te 1cm i raro i te trochanter iti
I roto i te poto, he taputapu rongoā te PFN-A, ā, ko te A2 te momo whati. I roto i te haumanu, ka whiriwhiria e ngā tākuta te tikanga whakatikatika ā-roto e tika ana i runga i te whakarōpūtanga AO o te whati o te tūroro (pēnei i te momo A2), ā, ko te PFN-A tētahi o ngā tikanga pokanga noa mō te rongoā i ngā whati femur intertrochanteric kāore i te pumau pērā i te momo A2.
