Mumakore achangopfuura, nekukwegura kwevanhu, kuwanda kwekutyoka kwechiuno chepamberi petsoka kwave kuwedzera gore negore. Zvichienderana nenhamba dzisina kukwana, paive nevarwere vanosvika mamiriyoni 1.66 vane chirwere chemapfupa ane chekuita neosteoporosis pasi rose muna 1990, uye nhamba iyi inotarisirwa kusvika mamiriyoni 6.26 panosvika gore ra2050.
Varwere vakwegura vane mapfupa akatyoka eparutivi pechifuva vanosangana nehuwandu hwakawanda hwerufu nekuda kwemamiriro ezvinhu emuviri uye matambudziko akasiyana-siyana. Pakati pavo, huwandu hwerufu rwemapfupa akatyoka eparutivi pechifuva hunosvika 15%–20%.
Kutyoka kwechiuno pakati petrochanteric rudzi rwekutyoka kwechiuno kwakajairika muvarwere vakwegura, kunyanya avo vane osteoporosis. Kusiyana neizvi, varwere vadiki vanowanzo tambura nekukuvara kwemusoro kunokonzerwa nesimba rakawanda.
Kurapa kwekupwanyika kwemapfupa emukati metrochanteric kunosanganisira nzira dzakasiyana siyana:
Kugadzika kwekunze kwemedullary, senge dynamic hip screw (DHS), dynamic condylar screw, nezvimwewo.
Kugadziriswa kwemukati memedullary, sengeGammaNmurwi, Pnzara yeFemur(PFN), iri pedyonzara yemukadziantirotation (PFNA), Intertan, nezvimwewo.
Nhasi tinoda kusumaChipikiri cheIntramedullary chakabatanatekinoroji.
Chinhu chikuru chakanakiraTitanium FemoralNail iri munzvimbo yavo yemukati memedullary, iyo inopa rutsigiro rwemuchina mukati memedullary uye inodzivirira kudonha kwakanyanya, uye izvi hazvinei nekuti lateral cortex ine simba rekutsigira here.
Pamusoro pezvo, nzvimbo yemukati medullary ine ruoko rupfupi rwenguva pfupi inopa zvakanakira zve biomechanical uye inogona kuderedza kuitika kwekuneta kwemidziyo yekugadzirisa mukati. Panguva imwecheteyo, sisitimu yekugadzirisa mukati memedullary hainyanyi kubatwa necoxa vara kunyangwe medial cortex ikarasikirwa nerutsigiro. Nokudaro, kuderedza nekugadzika kwakasiyana kwemapfupa e trochanter akaputsika hakukurudzirwi.

Nzara yemusoro yePFNA inoshandisa nzira yekukiya banga rinotenderera. Banga iri rine nzvimbo yakakura uye dhayamita yepakati inowedzera zvishoma nezvishoma. Kana rabatwa mumapfupa, banga rinotenderera rinogona kutenderera roga, richimanikidza mapfupa, nokudaro richichengetedza mapfupa uye richibata mapfupa nebanga zviri pedyo.
Izvi zvinowedzera simba rekubata rebanga rinotenderera. Panguva imwe chete, rinopa simba rekudzivirira kutenderera uye kugadzikana kwekona, izvo zvinogona kuderedza kuwanda kwezvirema zvakaita secoxa vara.
