I nā ʻeha ʻeha, hoʻonui kēia ala i ka nui o ka maʻi i ka 15-25% a hoʻopiʻi i ka hoʻōla ʻana o ka ʻiʻo palupalu. Hōʻalo ʻo Retrograde intramedullary nailing (DTN) i kēia mau pilikia ma ka hoʻohana ʻana i kahi wahi komo kuʻekuʻe wāwae liʻiliʻi, e hāʻawi ana i nā hopena maikaʻi loa i nā hiʻohiʻona kahi e hakakā nui ai ka hoʻoponopono ʻana i ka pā.
