Tikanga Pokanga | “Tikanga Here Āwhata Waea Kirschner” mō te Whakapūmau ā-Roto i roto i te Maimoatanga o te Whati o Bennett

Ko te whati o Bennett te take o te 1.4% o ngā whati ringa. He rerekē te nekehanga o te whati Bennett i ngā whati noa o te turanga o ngā wheua metacarpal. Ka mau tonu te wāhanga mata hononga proximal ki tōna tūranga anatomical taketake nā te kukume o te ligament metacarpal oblique, ko te wāhanga distal ia, nā te kukume o ngā uaua abductor pollicis longus me adductor pollicis, ka neke ki te dorsoradial ka piko ki runga.

Mō ngā whati o Bennett kua nekehia, ka tūtohuhia te maimoatanga pokanga kia kore ai e whakararu i te tūnga o te hononga carpometacarpal me te mahi a te koromatua. Mō ngā tikanga maimoatanga pokanga, he whānuitia te whakamahinga o ngā pūnaha whakapiri pereti me te tīwiri, me te whakapiri ā-roto o te waea Kirschner, i roto i te mahi haumanu. Kua whakaarohia e ngā tohunga o te Hōhipera Tuatoru o Hebei he tikanga whitiki whakapiri waea Kirschner, e uru ana ki tētahi tapahi iti iti te whakaekenga hei whakatika i ngā whati o Bennett, ā, ka puta he hua pai.

Hipanga 1: Tapahia he 1.3 cm te whānui ki te taha radial o te hononga carpometacarpal, tapahia papatahi i te papatahi kia kitea te wāhi, hoki whakamuri te abductor pollicis longus ki te taha ulnar, ka whakaaturia te taha tuara o te hononga carpometacarpal.

Hipanga 2: Whakamahia te tōia ā-ringa, ka whakatōkia te koromatua kia iti ai te whati. Whakauruhia he waea Kirschner 1 mm te roa mā te pito whati tawhiti, 1-1.5 cm te tawhiti atu i te hononga carpometacarpal, hei whakapiri i te kongakonga wheua proximal. Kia uru te waea Kirschner ki te kongakonga wheua, haere tonu ki te neke whakamua mā te 1 cm.

Hipanga 3: Tangohia he waea ka takai kia rite ki te āhua waru huri noa i ngā pito e rua o te waea Kirschner, kātahi ka whakau ki tōna tūranga.

Kua whakamahia te tikanga here taura Kirschner i roto i te maha o ngā whati, engari mō ngā whati a Bennett, he maha ngā wā ka kore e kitea pai te whati, ā, ka uaua te mahi. Hei tāpiri, ki te pakaru te whati, kāore pea e taea e te waea Kirschner kotahi te whakau i te kongakonga wheua tata. Tērā pea he iti noa iho tōna whai huatanga haumanu. Haunga te tikanga whakau here taura kua whakahuatia ake nei, kei reira anō te whakau waea Kirschner me te tikanga here taura, kua pūrongohia hoki i roto i ngā tuhinga.
