Whakarāpopototanga Whakahaere
Ko tenei rangahau take haumanu e whakaatu ana e rua nga tuuroro kaumātua e mau ana i nga whati whawhati tata o te humeral e whakahaeretia ana Nga punaha whao intramedullary XC Medico . I tutuki nga turoro e rua i te whakahekenga tinana, te whakakotahitanga pakari, me te pai o te mahi whakaora ahakoa te nui o te osteoporosis me te uaua o te whati.
Nga kitenga haumanu matua:
- ✓ Ko te whao intramedullary e whakarato ana i te pai o te koiora koiora i roto i nga wheua osteoporotic ka whakaritea ki te whakatikatika pereti
- ✓ Ko te huarahi whakaeke iti ka whakaiti i te kino o te kiko ngohengohe me te wa mahi ma te 25-30%
- ✓ Ko te hoahoa tiritiri kawenga o nga whao IM ka taea te whakakorikori moata me te kore e whakararu i te whakaora whati
- ✓ Ko nga putanga mahi e rua tau (Constant-Murley scores 62-64) e whakaatu ana i te mauroa me te pai o te manawanui
Whakataki Hangarau Hangarau
Na te whao intramedullary (IM) e whakaaehia ana mo nga pakaru o te humeral tata, he mea nui te mohio ki nga tikanga pokanga tika[tohu: 6]. Kaore i rite ki te whakatikatika pereti, ka mahi nga whao IM hei taputapu tiritiri kawenga , ko te tikanga kaore i te whakawhirinaki katoa te pumau ki te hoko wiri i roto i nga wheua osteoporotic[tohu: 5]. Ko tenei rereketanga nui ka tino pai te whao IM ki nga turoro pakeke kua paheke te kounga o te wheua [whakahua: 4].
Nga Tikanga Hangarau Matua
- Te Whakaiti Anatomic: He mea tino nui te whakahoki i te koki o te upoko-kakau me te aukati i te hekenga varus [cite: 4]
- Pumautanga Waenga: Me whakahoki ano te hinge waenga kia kore ai te anga o te varus [cite: 4]
- Whakaritea Tiri-Uta: Ko nga whao IM ka pumau tonu me te kore e hiahia te whakakotahitanga koiora [whakahua: 5]
- Tikanga Whakangungu Iti: Ka whakaitihia te mamae o te kiko ngohe me te wa mahi ka whakaritea ki te whakatikatika pereti tuwhera [whakahua: 4]
I roto i nga wheua osteoporotic, kua whakaatuhia e te whao IM te hiranga o te koiora[tohu: 5]. Ko te whakatikanga tiritiri kawenga ka taea e te whao ake te pumau i te wa e whakatairanga ana i te hanga waea[tohu: 5]. He rereke tenei ki te whakatikatika i te pereti, he kawenga te kawenga me te arahi ki te whakamarumaru ahotea.
Te Ara Haparapara me te Tohu Whakauru
Ko te huarahi whakawehenga deltoid e whakarato ana i te tino whakakitenga i te wa e whakaiti ana i te kino o te kaitahuri hurihuri[whakahua: 10]. Ka kitea te whati, ka taea te whakaheke tinana ma te whakamahi i te arataki fluoroscopic me nga tikanga whakaheke koa.
Te Whakaritenga Waa Medullary
He mea tino nui te waahi urunga[cite: 8]. Ko te tuunga ki waenga ki te kohanga supraspinous me te taha ki te taha o te humeral, ka whakarite i te huarahi whao tino pai[whakahua: 10]. Ka whakanekehia he waea arataki ma roto i te awaawa, ka mahia te reaming raupapa hei whakarite i te awa mo te whakaurunga implant[tohu: 10].
Take 1: Te Waahanga Wha-waahanga Matatini me te Osteoporosis Tino
Tuhinga o nga turoro
Patient: Rosa María Escobar (anonymized)
Age: 67 years old [cite: 18]
Ira tangata: Wahine [cite: 18]
Mechanism of Injuries: He iti te kaha o te tukinga o te motuka motuka i te wa e eke paihikara ana; te paanga tika ki te pakihiwi maui [cite: 19]
History Medical: Tuhituhi osteoporosis (T-score -2.8); i runga i te rongoa bisphosphonate mo te 6 tau [whakahua: 19]
Iwi Kiato: Humeral head BMD 58 HU (he osteoporosis kino)
Atahanga o mua i te mahi
I whakaatuhia e Rosa María he wha-waahanga wha-waahanga a Hertel i te taha taha o te humeral e tohuhia ana e [whakahua: 21]:
- Kua oti te nekehia o te upoko humeral me te angulation varus (18° mai i te tuaka anatomic) [cite: 20, 21]
- He nui ake te nekehanga o te ngongo >10mm
- Te whakakotahitanga o te rohe kaki pokanga
- Te kounga o te wheua osteoporotic kino (BMD 58 HU)
Intramedullary Nail Fixation
Hua i whakamahia: XC Medico Multi-Lock Humerus Intramedullary Nail System
I runga i te osteoporosis kino me te tauira whati wha-waahanga, i tohua te whakatikanga titi IM i runga i te whakatikatika pereti na te mea[tohu: 23]:
- He 250-350 N anake te kaha o te unu i te 58 HU, me te 600-800 N me te whao IM whakanuia.
- Ko te hoahoa tiritiri kawenga e whakatairanga ana i te whakaora whati i roto i nga wheua kounga kore [cite: 5]
- Ko te huarahi whakaeke iti ka whakaiti i te wa mahi ma te 30-40 meneti [cite: 4]
- Ko te raka tata-maha ka tohatoha i nga kawenga puta noa i te hanganga whare herehere ahu-toru [whakahua: 8]
Nga Putanga Haparapara
Nga Taipitopito Mahi: 95 meneti te wa mahi | 140 mL kua mate toto | 3 whakaahua fluoroscopic
Whakaora i muri i te mahi:
- POD 1: Te mamae VAS 2/10; 20° te toronga whakamua; karekau he raruraru [cite: 23]
- 6 wiki: Whakawhiti whakamua 65°, hurihanga waho 25°, mamae VAS 1/10; ka kitea te hanganga o te waea [cite: 23]
- 12 wiki: Whakawhiti whakamua 95°, Constant-Murley 58/100; hoki ki te marama ADL [whakahua: 23]
- 1 tau: Whakawhiti whakamua 125°, kahaki 110°, Constant-Murley 62/100; hoki ki te mahi maara me nga mahi katoa [cite: 25]
Take 2: Te Waahanga Wha-waahanga Kua Hurihia me te Rahunga Maimoatanga Manaakitanga
Tuhinga o nga turoro
Patient: Javier Mendoza (anonymized)
Age: 72 years old [cite: 27]
Ira: Tane [cite: 27]
Mechanism of Injury: Hinga mai i te teitei tu; te ngana ki te kawe pikaunga o te pito o runga [whakahua: 28]

Iwi Kiato: Humeral head BMD 62 HU (he osteoporosis kino)
Akoranga Haumanu: Karekau te Tiaki Manaakitanga
I te tuatahi ka tukuna e Javier te wha-waahanga o te whaa o te humeral o te taha tata, a, i whakahaerehia marietia me te kore e nekehia [whakahua: 29, 32]. Heoi, ko nga reo irirangi tukurua i te wiki kotahi e whakaatu ana i te heke haere o te varus me te nui ake o te nekehanga o te ngongo, e tohu ana i te koretake o te whati[tohu: 32]. Ko tenei wawaotanga pokanga i whakahauhia [cite: 32].
Te wawaotanga pokanga
Hua i whakamahia: XC Medico Humeral Intramedullary Nail System
I runga i te pakeke o Javier, te maha o nga mate (tino ngawari te COPD), me te neke haere o te whati, i whiriwhiria te whao IM ki te whakaiti i te wa mahi i te wa e tutuki ai te pumau i roto i nga wheua osteoporotic[cite: 4, 32].
Nga Taipitopito Mahi: 92 meneti te wa mahi | 155 mL kua mate toto | Maukati tata-maha-marama me nga wiri e toru (45°/90°/135°) [cite: 8]
Te ahunga whakamua i muri i te mahi
- POD 1: I timata te whakakorikori moata; mamae VAS 2/10; tino pai te whakahekenga tinana i whakapumauhia i runga i te whakaahua [whakahua: 10, 32]
- POD 3: Ka tukuna ki te kainga me te rongoa tinana; mamae pai te whakahaere i runga i nga rongoa waha [whakahua: 34]
- 6 wiki: Whakawhiti whakamua 70°, hurihanga waho 30°, mamae VAS 1/10; ka kitea te pirititanga o te waea [cite: 34]
- 12 wiki: Whakawhiti whakamua 105°, Constant-Murley 60/100; motuhake i roto i te ADL [whakahua: 34]
- 2 tau: Whakawhitinga whakamua 120°, kahaki 105°, Constant-Murley 64/100; te whakakotahitanga o nga wheua; karekau he taputapu e wetekina ana [cite: 34]

Whakamutunga
Ko te whao i roto i te whao o nga whati humeral tata i roto i nga turoro osteoporotic tawhito e tohu ana i te paerewa tiaki o naianei mo nga tauira whati uaua (e toru me te wha-waahanga) [whakahua: 6]. Ko te punaha Maha-Maukati a XC Medico, me tana raka tata tata-maha me te tiritiri kawenga, ka puta nga hua pai ake i whakaritea ki te whakatikatika pereti tuku iho[tohu: 5, 8].
Ko nga keehi e rua i whakaatuhia - Ko te whakaora tere a Rosa María mai i te wha-waahanga whawhati [whakahua: 25] me te whakaoranga a Javier o te maimoatanga i rahua [whakahua: 34] - e whakaatu ana i te uara haumanu o tenei huarahi. Ko nga hoa o te hohipera me te tohatoha e whakamahi ana i nga hangarau whao IM ka taea te tumanako he wa poto ake te mahi, he iti ake nga reeti whakapouritanga, he pai nga hua mahi mo te wa roa, me te painga whakataetae kaha i roto i te maakete trauma[tohu: 42].
