ʻenehana ʻokiʻoki | "Kirschner Wire Tension Band Technique" no ka hoʻoponopono i loko i ka mālama ʻana i ka haʻi o Bennett.

ʻO ka haʻihaʻi o Bennett he 1.4% o nā haʻi lima. ʻAʻole like me nā haʻihaʻi maʻamau o ke kumu o nā iwi metacarpal, ʻokoʻa ka neʻe ʻana o kahi haʻi Bennett. Hoʻopaʻa ʻia ka ʻāpana proximal articular surface i kona kūlana anatomical mua ma muli o ka huki ʻana o ka ligament metacarpal oblique, ʻoiai ka ʻāpana distal, ma muli o ka traction o ka abductor pollicis longus a me adductor pollicis tendons, dislocates dorsoradially a me supinates.

No nā haʻihaʻi o Bennett i hoʻoneʻe ʻia, ʻoi aku ka maʻamau o ka mālama ʻana i ka ʻokiʻoki e pale i ka hoʻopololei ʻana o ka hui carpometacarpal a me ka hana manamana lima. Ma ke ʻano o nā ʻano hana lapaʻau, nā ʻōnaehana pale a me nā screw fixation, a me Kirschner wire internal fixation, hoʻohana nui ʻia i ka hana lapaʻau. Ua noi aku nā kānaka ʻepekema mai ka Halemai ʻEkolu o Hebei i kahi ʻenehana Kirschner wire tension band, e pili ana i kahi ʻoki liʻiliʻi liʻiliʻi e hoʻoponopono i nā haʻihaʻi o Bennett, e loaʻa ana nā hopena maikaʻi.

KaʻAnuʻu Hana 1: E hana i kahi ʻoki 1.3 knm ma ka ʻaoʻao radial o ka hui carpometacarpal, e ʻoki i ka papa ma ka papa e hōʻike i ka wahi, e hoʻihoʻi i ka pollicis longus abductor ma ka ʻaoʻao ulnar, a e hōʻike i ka ʻaoʻao hope o ka hui carpometacarpal.

KaʻAnuʻu Hana 2: E hoʻopili i ka traction manual a pronate i ka manamana lima e hōʻemi i ka haki. E hoʻokomo i kahi uea Kirschner 1 mm ma ka ʻaoʻao haʻihaʻi, 1-1.5 knm ka mamao mai ka hui carpometacarpal, e hoʻoponopono i ka ʻāpana iwi kokoke. Ma hope o ke komo ʻana o ka uea Kirschner i ka ʻāpana iwi, e hoʻomau i ka neʻe ʻana ma ka 1 knm.

KaʻAnuʻu Hana 3: E lawe i kahi uwea a hoʻopaʻa iā ia ma kahi ʻano helu-ʻewalu a puni nā ʻaoʻao ʻelua o ka uea Kirschner, a laila hoʻopaʻa i kahi.

Ua hoʻohana ʻia ka ʻenehana Kirschner wire tension band i nā haʻihaʻi he nui, akā no nā haʻihaʻi o Bennett, ʻo ka ʻoki liʻiliʻi e hopena pinepine i ka ʻike maikaʻi ʻole a paʻakikī ke kaʻina hana. Eia hou, inā hoʻopili ʻia ka haʻihaʻi, ʻaʻole hiki i kahi uea Kirschner ke hoʻopaʻa pono i ka ʻāpana iwi kokoke. Hiki ke kaupalena ʻia kāna hana lapaʻau. Ma waho aʻe o ke ʻano o ka hoʻopaʻa ʻana i ka band tension i ʻōlelo ʻia aʻe nei, aia pū kekahi Kirschner uea fixation i hui pū ʻia me kahi ʻenehana hoʻopaʻapaʻa, i hōʻike ʻia ma ka palapala.
