Xikongomelo xa xisekelo xa ku khoma ku tshoveka i ku tiyisisa marhambu lama tshovekeke, ku endla leswaku marhambu lama vavisekeke ma hola hi ku hatlisa, ni ku vuyisa ku famba-famba ka ha ri ni nkarhi ni ku tirha hi ku helela ka marhambu lama vavisekeke.

External fixation i endlelo leri tirhisiwaka ku pfuneta ku horisa marhambu lawa ya tshovekeke swinene. Muxaka lowu wa vutshunguri bya marhambu wu katsa ku tiyisisa ku tshoveka hi xitirhisiwa xo hlawuleka lexi vuriwaka fixator, lexi nga ehandle ka miri. Hi ku tirhisa swikwirikiri swo hlawuleka swa marhambu (leswi hi ntolovelo swi vuriwaka tiphini) leswi hundzaka eka nhlonge ni misiha, fixator yi hlanganisiwa ni marhambu lama onhakeke leswaku ma tshama ma ri eku ringaniseni loku faneleke loko ma ri karhi ma hola.

Xana xisirhelelo xa le handle xi tirhisiwa yini?

Xitirhisiwa xo khoma xa le handle xi nga ha tirhisiwa ku hlayisa marhambu lama tshovekeke ma tshamisekile naswona ma ringanana. Xitirhisiwa lexi xinga lulamisiwa ehandle kutiyisisa leswaku marhambu yatshama eka xiyimo lexinene hinkarhi wa ku hola. Xitirhisiwa lexi xitala kutirhisiwa eka vana na loko nhlonge ehenhla ka ndzhawu leyi tshovekeke yi onhakile.

Hi tihi tinxaka ta xisirhelelo xa le handle?

Kuna tinxaka tinharhu ta xisekelo ta ti fixators tale handle: standard uniplanar fixator, ring fixator, na hybrid fixator.

Switirhisiwa swo tala leswi tirhisiwaka ku khoma swilo endzeni swi avanyisiwile hi swiyenge swi nga ri swingani leswikulu: tintambhu, tiphini ni swikwirikiri, tipuleti ni swipikiri kumbe tinhonga ta le ndzeni ka khwiri.

Ti staples nati clamps titlhela titirhisiwa nkarhi wun’wana eka osteotomy kumbe fracture fixation. Ti autogenous bone grafts, allografts, na bone graft substitutes switala kutirhisiwa eka ku tshungula swihoxo swa marhambu leswi vangiwaka hi swivangelo swohambana hambana. Eka ku tshoveka loku tluleriweke swin’we ni ku tshungula mavabyi ya marhambu, vuhlalu bya swidlaya-switsongwatsongwana byi tala ku tirhisiwa.

Dynamic Axial Proximal Femoral Fragment Xisirhelelo xa le handle: Nkatsakanyo lowu heleleke

Ku tshoveka ka tinyonga i xiphiqo lexi tolovelekeke xa marhambu, ngopfu-ngopfu eka vanhu lava dyuhaleke. Ku tshoveka loku ku nga vanga mavabyi lamakulu ni ku fa, naswona vulawuri bya kona hakanyingi byi rharhanganile. Yin’wana ya tindlela leti tirhisiwaka ku lawula ku tshoveka ka xirhendze i dynamic axial proximal femoral fragment external fixator (DAPFFEF). Eka xitsalwana lexi, hi ta nyika nkatsakanyo lowu heleleke wa DAPFFEF, ku katsa na swikombiso swa yona, thekiniki, swiphiqo, na mimbuyelo.

Manghenelo

Ku tshoveka ka tinyonga i xiphiqo lexikulu xa rihanyo ra vaaki, laha ku ringanyetiwaka leswaku timhangu ta 1,6 wa timiliyoni ti humelela emisaveni hinkwayo lembe na lembe. Ku tshoveka loku ku fambelanisiwa na mavabyi yale henhla na ku fa, ngopfu ngopfu eka vavabyi lava dyuhaleke. Hakanyingi ku lawula ku tshoveka ka swikunwana swa rharhanganile naswona ku tirhisiwa tindlela to hambana-hambana ta vuhandzuri ku swi lawula. Yin’wana ya tithekiniki leti i dynamic axial proximal femoral fragment external fixator (DAPFFEF).

Anatomy ya Xirhendzevutani

Loko hinga se burisana hi DAPFFEF, i swa nkoka ku twisisa anatomy ya xirhendze. Nhlanganelo wa xirhendze i nhlangano wa bolo na socket, lowu vumbiwaka hi acetabulum ya pelvis na nhloko ya femoral. Nhamu ya femoral yi hlanganisa nhloko ya femoral na shaft ya femoral. Proximal femur i xiphemu xa femur lexi nga ekusuhi swinene na hip joint.

Xana i yini xisirhelelo xa le handle xa Dynamic Axial Proximal Femoral Fragment?

Dynamic axial proximal femoral fragment external fixator (DAPFFEF) i xitirhisiwa lexi tirhisiwaka ku tiyisisa ku tshoveka ka proximal femur. Xitirhisiwa lexi xi na sete ya tiphini kumbe swikwirikiri leswi nghenisiwaka eka proximal femur naswona swi hlanganisiwa na furemu ya le handle. Fureme yi endla leswaku marhambu lama tshovekeke ma tiya, leswi endlaka leswaku ma hola.

Swikombiso swa DAPFFEF

DAPFFEF yi tirhisiwa ku tshungula ku tshoveka ka proximal femur, ku katsa na ku tshoveka ka subcapital, ku tshoveka ka intertrochanteric, na ku tshoveka ka subtrochanteric. Yitlhela yitirhisiwa ku tshungula non-unions na malunions ya proximal femur.

Thekiniki ya DAPFFEF

Thekiniki ya DAPFFEF yi katsa ku nghenisa tiphini kumbe swikwirikiri eka proximal femur, leswi endzhaku swi hlanganisiwaka na furemu ya le handle. Tiphini kumbe swikwirikiri swi nghenisiwa hi ndlela leyi pfumelelaka ku tirha tani hi voko ra lever, leswi nyikaka dynamic compression eka marhambu lawa ya tshovekeke. Fureme yi lulamisiwa ku fikelela mpimo lowu lavekaka wa ntshikelelo.

Swipfuno swa DAPFFEF

Swipfuno swa DAPFFEF swikatsa vuswikoti bya yona byo nyika ku khomiwa loku tiyeke ka proximal femur, vuswikoti bya yona byo nyika dynamic compression eka marhambu lawa ya tshovekeke, na vuswikoti bya yona byo pfumelela ku rhwala ntiko ka ha ri na nkarhi. Swilo leswi swi nga endla leswaku ku va ni vuyelo lebyi antswisiweke ni minkarhi yo hatlisa yo hola eka vavabyi.

Swiphiqo swa DAPFFEF

Swiphiqo swa DAPFFEF swi katsa ku tluleriwa hi ti pin tract, ku nga vi na nhlangano, malunion, ku lahlekeriwa hi ku hunguteka, na ku tsandzeka ka implant. Swiphiqo leswi swi nga lawuriwa hi vutshunguri lebyi faneleke, ku katsa ni swidlaya-switsongwatsongwana, vuhandzuri byo pfuxeta ni ku susiwa ka fixator.

Mimbuyelo ya DAPFFEF

Mimbuyelo ya DAPFFEF yi kamberiwile eka swikambelo swo hlayanyana swa tliliniki. Mikambelo leyi yi kombisile leswaku DAPFFEF yi nga nyika ku khomiwa loku tiyeke ka proximal femur, leswi pfumelelaka ku rhwala ntiko ka ha ri na nkarhi na mimbuyelo leyi antswisiweke eka vavabyi.

Mahetelelo

Dynamic axial proximal femoral fragment external fixator (DAPFFEF) i endlelo ra vuhandzuri leri tirhisiwaka ku tiyisisa ku tshoveka ka proximal femur. Yi nyika ku khomiwa loku tiyeke na ku tshikileriwa loku cinca-cincaka eka marhambu lama tshovekeke, leswi pfumelelaka ku rhwala ntiko ka ha ri na nkarhi na mbuyelo lowu antswisiweke eka vavabyi. Swiphiqo swi nga humelela, kambe swi nga lawuriwa hi vutshunguri lebyi faneleke.
