Ngā āhuatanga haumanu o te "whara kihi" o te hononga tuke

Ko ngā whati o te pane radial me te kaki radial he whati noa o ngā hononga tuke, he maha ngā wā ka puta mai i te kaha axial, i te ahotea valgus rānei. Ina tū te hononga tuke ki te tūranga torotika, 60% o te kaha axial i runga i te ringaringa ka tukuna ki te taha proximal mā te pane radial. Whai muri i te whara o te pane radial, te kaki radial rānei nā te kaha, ka pā pea ngā kaha kutikuti ki te capitulum o te humerus, ka arahi pea ki ngā whara wheua me te kiriuhi.

I te tau 2016, i tautuhia e Claessen tētahi momo whara motuhake i haere tahi ai ngā whati o te pane/kaki radial me te kino o te wheua/karetā ki te capitulum o te humerus. I tapaina tēnei āhuatanga ko te "ngoi kihi," me ngā whati i whakaurua ai tēnei huinga i kiia ko te "whati kihi." I roto i tā rātou pūrongo, i whakaurua e rātou ngā kēhi 10 o ngā whati kihi, ā, i kitea e 9 ngā kēhi he whati pane radial i whakarōpūtia hei momo Mason II. E kī ana tēnei me ngā whati pane radial momo Mason II, me whakanui ake te mōhiotanga mō ngā whati pea o te capitulum o te humerus.

I roto i ngā mahi haumanu, he tino ngāwari te tātaritanga hē o ngā whati kihi, inā koa i ngā wā e nekehia nuitia ana te whati o te upoko/kaki radial. Ka taea e tēnei te arahi ki te kore e aro ki ngā whara e pā ana ki te capitulum o te humerus. Hei tirotiro i ngā āhuatanga haumanu me te auau o ngā whati kihi, i whakahaerehia e ngā kairangahau o tāwāhi he tātaritanga tatauranga i runga i te rahi tauira nui ake i te tau 2022. Ko ngā hua e whai ake nei:

I roto i te rangahau, i whakaurua he katoa o ngā tūroro 101 he whati te upoko/kaki radial i rongoatia i waenga i te tau 2017 me te tau 2020. I runga i te mea he whati te upoko o te humerus i te taha kotahi, i wehea ngā tūroro kia rua ngā rōpū: te rōpū upoko (Rōpū I) me te rōpū kāore i te upoko (Rōpū II).

I tua atu, i tātarihia ngā whati o te pane radial i runga i tō rātou tūranga tinana, i wehea kia toru ngā rohe. Ko te tuatahi ko te rohe haumaru, ko te tuarua ko te rohe waenga o mua, ā, ko te tuatoru ko te rohe waenga o muri.

I whakaatuhia e ngā hua o te rangahau ngā kitenga e whai ake nei:

1. Ko te teitei ake o te whakarōpūtanga Mason mō ngā whati pane radial, ko te nui ake o te mōrearea o ngā whati capitulum. Ko te tūponotanga o te hononga o te whati pane radial momo Mason I ki te whati capitulum he 9.5% (6/63); mō te momo Mason II, he 25% (6/24); ā, mō te momo Mason III, he 41.7% (5/12).

1. I te horapa o ngā whati o te pane radial ki te kaki radial, ka heke te mōrearea o ngā whati o te capitulum. Kāore i kitea i roto i ngā tuhinga tētahi kēhi takitahi o ngā whati o te kaki radial e haere tahi ana me ngā whati o te capitulum.

1. I runga i ngā rohe hanganga tinana o ngā whati pane radial, he nui ake te mōrearea o ngā whati kei roto i te "rohe haumaru" o te pane radial ki te hono atu ki ngā whati capitulum.

▲ Te whakarōpūtanga o ngā whati pane radial mā te whakamahi i te masonry.

▲ He take o te whati kihi i te tūroro, i whakauhia ai te pane radial ki te pereti maitai me ngā tīwiri, ā, i whakauhia te pane o te humerus ki te whakamahi i ngā tīwiri Matotoru.
