Abavelisi abaPhezulu abali-10 eMelika: iiPleti zokutshixa i-Distal Humerus ( ngoMeyi 2025)

I-Anatomy ye-Distal Humerus

I-distal humerus ihlukaniswe kwikholamu ye-medial kunye nekholamu esecaleni.

Umhlathi ophakathi

Ikholamu ephakathi ibandakanya inxalenye ephakathi ye-metaphysis ye-humerus, i-epicondyle ephakathi, kunye ne-condyle ephakathi, kuquka i-trochlea ye-humerus.

IKholam esecaleni

Ikholamu esecaleni iquka inxalenye esecaleni ye-metaphysis ye-humerus, i-epicondyle esecaleni, kunye ne-condyle esecaleni, kuquka i-capitulum ye-humerus.

I-Coronoid Fossa kunye ne-Olecranon Fossa

Ibekwe phakathi kwezi zintlu zimbini kukho i-coronoid fossa yangaphambili kunye ne-posterior olecranon fossa.

I-Mechanism yokulimala kwi-Distal Humerus Fractures

I-distal humerus ihlukaniswe kwikholamu ye-medial kunye nekholamu esecaleni.

Kutheni i-distal humerus ithanda ukuphuka?

Njengenxalenye ebalulekileyo ye-elbow joint, i-distal humerus fractures idla ngokuphuma 'kwi-trauma ethe ngqo' (efana nokuwa phantsi kwengqiniba) okanye 'i-indirect trauma' (efana nokujija okanye ukujula).

-Izihlunu Zokutsalwa KwezihlunuLateral Column

Ikholamu ephakathi ibandakanya inxalenye ephakathi ye-metaphysis ye-humerus, i-epicondyle ephakathi, kunye ne-condyle ephakathi, kuquka i-trochlea ye-humerus. ·Ukuqina okuqinileyo kwemisipha yangaphakathi yokujikeleza ·Ukunyanzeliswa okuqinileyo kwe-elbow flexor muscles

-I-High-Energy Trauma

Amandla angaphandle afana neengozi zendlela okanye ukuwa ukusuka kumphakamo kunokubangela ukuphuka okuncinciweyo okanye ukubandakanya umphezulu we-articular.

UHlelo lwe-AO: Ukuchwetheza ngokuchanekileyo ukuKhokela iZigqibo zoTyando

Ngokwenkqubo yokuhlelwa kwe-AO, i-distal humerus fractures ihlelwa ngolu hlobo lulandelayo, luchaphazela ngokuthe ngqo ukhetho lwezicwangciso zonyango:

Uhlobo A: Iifractures ezongezelelweyo ze-articular

- A1: Ukuqhekeka okulula, akukho nxaxheba ye-articular. - I-A2 / A3: I-fractures ye-metaphyseal echaphazelekayo okanye efudukayo, ingqalelo efunekayo ngenxa yokukhubazeka kwe-angular.

Uhlobo B: Inxalenye ye-articular fractures

Umgca wokuqhekeka ubandakanya indawo edibeneyo kodwa ngaphandle kokuhlukana okupheleleyo; ukunciphisa i-anatomical kuyimfuneko ukubuyisela ukuhambelana okuhlangeneyo.

Uhlobo C: Gqibezela i-articular fractures

- C1 / C2: Iifractures ezilula ze-intra-articular kunye nokubandakanyeka kwe-metaphyseal. - C3: I-intra-articular fractures edibeneyo, eyona nto inzima ukuyiphatha; ukulungiswa okuzinzile kuyadingeka ukunciphisa umngcipheko we-arthritis post-traumatic .. Loc

Ukubaluleka koHlelo:

Ulwahlulo lwe-AO lucacisa ubuzaza bokwaphuka kwaye lubonelela ngesikhokelo ekukhethweni kwepleyiti (umzekelo, iipleyiti ezingafaniyo nezimbini, uyilo lokutshixa izikrufu) ukuqinisekisa zombini amandla okulungisa kunye nolungelelwaniso lwebhayoloji.

Unyango loTyando: IiNzululwazi eziPhambili zePlate Fixation

Imigaqo yoNyango:

Ukulandela ifilosofi ye-AO: 'Ukunciphisa i-anatomical, ukulungiswa okuzinzile, kunye nokuzivocavoca kwangaphambili.'

I-High-Energy Trauma

Amandla angaphandle afana neengozi zendlela okanye ukuwa ukusuka kumphakamo kunokubangela ukuphuka okuncinciweyo okanye ukubandakanya umphezulu we-articular.

Imigaqo yoNyango

• Ukunciphisa i-anatomical

• Ukulungiswa okuzinzileyo

• Ukuzivocavoca kwangaphambili kokusebenza

Iimpawu zoCando

• Ukufuduswa kwe-Articular> 2mm

• Vula iifractures

• Ukulimala kwe-neurovascular kudibaniswe

• Ukungaphumeleli kunyango olulondolozayo

Isicwangciso soLungiso lwePlate

• Ubuchwephesha bePlati ezimbini

Ifanele uhlobo lwe-C fractures. Ukulungiswa ukusuka kumabini aphakathi (umzekelo, i-anatomical locking plate) kunye necala (umzekelo, i-parallel plate) emacaleni anikezela ukuzinza kwe-3D kunye nokunciphisa umngcipheko wokukhubazeka okujikelezayo emva kokusebenza.

• Ubuchule bePlati enye

Isetyenziselwa uhlobo A kunye nohlobo B lwezahlulo. Iipleyiti ezilungiselelwe kwangaphambili ezihambelana ne-distal humerus anatomy zinciphisa ukuchithwa kwezicubu ezithambileyo.

• Indlela eHlangeneyo encinci

Idityaniswe ne-percutaneous screw placement ukunciphisa umngcipheko wosulelo kunye nokugcina unikezelo lwegazi lweperiosteal.

Ixabiso leKlinikhi yoLungiso lwePlate

Inzuzo yeBiomechanical

Iipleyiti zokutshixa zibonelela ngokuzinza kwe-angular, ngakumbi kunenzuzo kwizigulana ze-osteoporotic.

Isiqinisekiso soBuyiselo esiSebenzayo

Ukunciphisa i-anatomical kugcina ukuhamba kwe-elbow joint ukuya kwinqanaba elikhulu, ukunciphisa iingxaki ezifana ne-nonunion okanye i-malunion.

Uyilo olulungiselelweyo

Iipleyiti ezibunjiweyo zeentlobo ezithile zokuphuka (umzekelo, iipleyiti zenkxaso ye-intercondylar ridge) ziphakamisa ukuhanjiswa kwamandla kunye nokukhawulezisa ukuphiliswa kwamathambo.
