I-distal humerus fractures luhlobo oluqhelekileyo lokulimala kwamandla aphezulu kwi-orthopedics. Ubunzima bonyango buxhomekeke kubunzima besakhiwo se-anatomical kunye nesidingo sokubuyisela umsebenzi odibeneyo. Njengomboneleli wesisombululo sobuchwephesha kwinkalo yokulungiswa kwangaphakathi kwamathambo, sinika uhlalutyo olunzulu lweendlela zokulimala, ukuhlelwa kwe-AO, kunye nezicwangciso zokulungiswa kweplate kwi-distal humerus fractures ukuxhasa unyango oluchanekileyo lwekliniki.

1. I-Anatomy ye-Distal Humerus
I-distal humerus iqukethe iikholomu zangaphakathi kunye necala, ezibandakanya i-epicondyles kunye ne-condyles.
2. Inkqubo yokwenzakala
Ukuqhekeka kwe-distal humerus kubangelwa kukwenzakala ngokuthe ngqo (umzekelo, ukuwa) okanye amandla angathanga ngqo (umzekelo, ukujija okanye ukutsalwa kwezihlunu).
3. Ukuhlelwa kwe-AO
Uluhlu lwe-AO luhlula i-distal humerus fractures kwiintlobo ezintathu eziphambili: A, B, kunye noC.
4. Unyango lotyando
Unyango lotyando lulandela imigaqo ye-AO: ukunciphisa i-anatomical, ukulungiswa okuzinzile, kunye nokuvuselelwa kwangaphambili.
5. Ixabiso loNyango
Iipleyiti zokutshixa zinika uzinzo oluphezulu lwe-biomechanical, ngakumbi kwithambo le-osteoporotic.
6. Iimodeli zePlati zeCZMEDITECH
I-CZMEDITECH inikezela ngeemodeli ezintathu: i-extraarticular (01.1107), i-lateral (5100-17), kunye ne-medial (5100-18) iipleyiti.

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
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 Ukutsalwa Forces
Ikholamu ephakathi ibandakanya inxalenye ephakathi ye-metaphysis ye-humerus, i-epicondyle ephakathi, kunye ne-condyle ephakathi, kuquka i-trochlea ye-humerus.
·Ukunyanzeliswa okuqinileyo kwezihlunu zangaphakathi ezijikelezayo
·Ukuqina okuqinileyo kwezihlunu ze-elbow flexor
-I-High-Energy Trauma
Amandla angaphandle afana neengozi zendlela okanye ukuwa ukusuka kumphakamo kunokubangela ukuphuka okuncinciweyo okanye ukubandakanya umphezulu we-articular.
I-Coronoid Fossa kunye ne-Olecranon Fossa
· Iingozi zendlela
·Ukuwa ukusuka phezulu

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 okuzinzileyo kuyafuneka ukunciphisa umngcipheko we-post-traumatic arthritis.
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.'
Umothuko waMandla aphezulu
Amandla angaphandle afana neengozi zendlela okanye ukuwa ukusuka kumphakamo kunokubangela ukuphuka okuncinciweyo okanye ukubandakanya umphezulu we-articular.
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
Ilungele 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.
