PFNA Nail: Inoshanda Orthopedic Solution

Proximal femoral fractures inoramba iri imwe yekukuvara kwakanyanya uye kwakaoma mukukuvara kwemapfupa, kunyanya pakati pevarwere vakwegura vane osteoporosis. Nekuwedzera kwehupenyu hwehupenyu uye chiitiko chepamusoro chekutyoka kwehudyu pasi rose, yakagadzika masisitimu ekugadzirisa anobvumira kuunganidza kwekutanga uye kuvimbika kwekupwanyika kuporeswa kwave kunonyanya kukosha kuchipatara.

Iyo PFNA chipikiri (Proximal Femoral Nail Antirotation) yakagadzirwa kugadzirisa izvi zvinodiwa. Nekubatanidza intramedullary load-sharing mechanics ine antirotation blade dhizaini, iyo PFNA sisitimu yave mhinduro inogamuchirwa nevakawanda yekusagadzikana proximal femoral fractures.

Ichi chinyorwa chinopa tarisiro yakazara yePFNA mbambo system, kusanganisira zviratidzo zvayo, biomechanical zvakanakira, kuvhiya misimboti, postoperative kupora, uye kufunga nezve njodzi.

Kunzwisisa iyo PFNA Nail System uye Yayo Dhizaini Pfungwa

Iyo PFNA chipikiri ndeye intramedullary fixation system yakanyatso kugadzirirwa kuputsika kweiyo proximal femur. Kusiyana neyakajairwa extramedullary zvishandiso, PFNA inoshanda padivi pemuchina axis yefemur, ichibvumira yakawedzera physiological mutoro kutamiswa.

Chinhu chinotsanangudza chePFNA system ndeye helical antirotation blade , iyo inobatanidza cancellous bone panguva yekuiswa. Iyi compaction inowedzera kutenga mukati meosteoporotic bone uye inovandudza kuramba kutenderera uye varus kudonha masimba. Nekuda kweizvozvo, PFNA inopa kugadzikana kwakawedzera zvichienzaniswa neyakajairwa lag screw-based masisitimu, kunyanya muvarwere vane hurombo hwemapfupa.

Clinical Zviratidzo uye Kusarudzwa Kwevarwere kwePFNA Nail Fixation

Common Proximal Femoral Fracture Pateni Yakabatwa nePFNA

PFNA zvipikiri zvinonyanya kuratidzwa kune mafractures anosanganisira proximal femur, kusanganisira:

• Intertrochanteric femoral fractures

• Kusagadzikana kana kuderedzwa kwetrochanteric fractures

• Subtrochanteric femoral fractures

• Reverse obliquity fracture mapatani

Aya marudzi ekutyoka anowanzo kupa biomechanical kusagadzikana, zvichiita kuti intramedullary fixation ive sarudzo inosarudzwa.

PFNA Nail Kushandisa muOsteoporotic uye Vakwegura Varwere

Osteoporosis inonyanya kukanganisa screw fixation simba mumusoro wemukadzi. Iyo PFNA antirotation blade inonyanya kubatsira mune idzi kesi, sezvo inomanikidza trabecular bone pane kuribvisa. Iyi dhizaini inoderedza njodzi yekudyara-kuchekwa-kunze uye kurasikirwa kwekugadzirisa, zvichiita kuti PFNA ive sarudzo yakavimbika kune vakura varwere vane osteoporotic hip fractures.

Biomechanical Advantages yePFNA Inofananidzwa neMamwe Magadzirirwo Systems

Mutoro-Kugovera Intramedullary Fixation uye Kutenderera Kugadzikana

Kubva pane biomechanical maonero, intramedullary zvipikiri zvinopa yepamusoro mitoro-kugovera kana ichienzaniswa neplate-based system. Iyo PFNA chipikiri inobatana padhuze neiyo femoral mechanical axis, ichideredza nguva dzekukotama panzvimbo yekutyoka.

Iyo antirotation blade inosimudzira kutenderera kugadzikana nekuwedzera pamusoro pekubata nekanzura pfupa, iyo inobatsira kuchengetedza kuderedzwa kwekutyoka pasi peaxial uye torsional mitoro panguva yekutanga kurema.
