Distal tibia fractures e emela 7-12% ea fractures eohle ea tibial 'me e baka mathata a ikhethang a ho buuoa. The distal tibia's anatomy-sebaka se pharaletseng sa metaphyseal hammoho le tšireletso e fokolang ea lisele tse bonolo karolong e ka pele-ea bohareng-e etsa hore ho behoa ha poleiti e bulehileng ho be kotsi maemong a sithabetsang ka likotsi tse sithabetseng kapa ho senyeha ho matla ha lisele tse bonolo.
Ho ea ka nalane, lingaka li ne li itšetlehile ka phokotso e bulehileng le ho lokisa poleiti, e hlokang ho phethoa ho hoholo ka pele-pele ka lithane tse sithabetseng maikutlo. Likotsing tse sithabetseng, mokhoa ona o eketsa sekhahla sa ts'oaetso ho 15-25% mme o thatafatsa pholiso ea lisele tse bonolo. Retrograde intramedullary nailing (DTN) e qoba mathata ana ka ho sebelisa sebaka sa maqaqailaneng se kenang maqaqailaneng, ho fana ka liphetho tse holimo maemong ao ho thata ho lokisa poleiti.
