"Bakeng sa ho robeha ha molala oa basali bao e seng ba tsofetseng, mokhoa o sebelisoang haholo oa ho lokisa ka hare ke sebopeho sa 'inverted triangle' se nang le likurufu tse tharo. Li-screw tse peli li behiloe haufi-ufi le li-cortices tse ka pele le tse ka morao tsa molala oa mosali, 'me sekurufu se le seng se behiloe ka tlase. Paterone ea '3-screw' e bonoa.
Ha li-screw li kenngoa ka holimo ho karolo e ka morao ea molala oa botšehali, ho baka kotsi ea ho ntša kotsi ea methapo ea methapo, e leng ho ka senyang phallo ea mali molaleng oa mosali, ka lebaka leo, ho ama ho fola ha masapo."
