Nā hopena o ka ʻoki ʻana o nā lālā haʻahaʻa

He hopena koʻikoʻi ka ʻoki ʻana o nā lālā haʻahaʻa i ka neʻe ʻana o nā hono a me nā ʻiʻo o ka lālā haʻahaʻa.Ma hope o ka ʻoki ʻana, hoʻemi pinepine ʻia ka wahi o ka neʻe ʻana o ka hui, ka hopena i nā ʻāpana ʻokoʻa ʻole i makemake ʻia a no laila paʻakikī ke uku ʻia me nā prostheses.No ka mea, ke alakaʻi ʻia nā prostheses o ka ʻaoʻao haʻahaʻa e ke koena lālā, he mea nui e hoʻomaopopo i ka hopena o ka ʻoki ʻana i nā hui nui a me ke kumu o ia mau loli.

(I) Nā hopena mai ka ʻoki ʻana i ka ʻūhā

ʻO ka lōʻihi o ke kumu he hopena koʻikoʻi i ka hana o ka hui pūhaka.ʻO ka ʻoi aku ka pōkole o ke kumu, ʻoi aku ka maʻalahi o ka ʻāʻī ʻana i ka ʻaihue, ka hoʻohuli ʻana i waho a me ka lohi.ʻO nā'ōlelo'ē aʻe, ma kekahiʻaoʻao, ua mālama ponoʻia ka gluteus medius a me ka gluteus minimus, ka mea nui i ka laweʻana i ka hip;ma ka ʻaoʻao ʻē aʻe, ua ʻoki ʻia ka hui ʻiʻo adductor i ka ʻāpana waena, e hopena i ka emi ʻana o ka ikaika o ka ʻiʻo.

(II) Nā hopena o ka ʻoki ʻana o ka wāwae haʻahaʻa

ʻAʻole i liʻiliʻi ka hopena o ka ʻoki ʻana i ka laulā o ka hoʻololi ʻana o ke kuli a me ka hoʻonui a me ka ikaika o ka ʻiʻo.ʻO ka quadriceps ka hui puʻupuʻu nui no ka hoʻonui a kū i ka tuberosity tibial;ʻO ka pūʻulu ʻiʻo nui e pāʻani ana i ka hoʻololi ʻana, ʻo ia ka puʻupuʻu ʻūhā hope, e kū ana ma kahi kokoke i ke kiʻekiʻe like me ka medial tibial condyle a me ka fibular tuberosity.No laila, ʻaʻole i pōʻino nā ʻiʻo ma luna i loko o ka lōʻihi maʻamau o ka ʻoki ʻana o ka wāwae haʻahaʻa.

(III) Nā hopena ma muli o ka ʻoki hapa ʻana o ka wāwae

ʻO ka ʻoki ʻana mai ka metatarsal a i ka manamana wāwae he mea liʻiliʻi a ʻaʻohe hopena i ka hana kaʻa.ʻO ka ʻoki ʻia mai ka hui tarsometatarsal (Lisfranc joint) i ke kikowaena.Hoʻokumu ia i kahi ʻano like ʻole ma waena o nā dorsiflexors a me nā flexors plantar, kahi e predisposes i ka hoʻololi ʻana o ka plantar flexion contracture a me ke kūlana hoʻohuli wāwae.ʻO kēia no ka mea ma hope o ka ʻoki ʻana, mālama ʻia ka hana o ke keiki triceps e like me ka plantar flexor prime mover, ʻoiai ua ʻoki loa ʻia nā tendons o ka hui dorsiflexor, pēlā e nalowale ai kā lākou hana kūpono.
