I-Distal humerus fractures iwuhlobo oluvamile lokulimala kwamandla aphezulu kuma-orthopedics. Ubunzima bokwelashwa buyinkimbinkimbi yesakhiwo se-anatomical kanye nesidingo sokubuyisela umsebenzi ohlangene. Njengomhlinzeki wesisombululo ochwepheshe emkhakheni wokulungiswa kwangaphakathi kwamathambo, sihlinzeka ngokuhlaziywa okujulile kwezinqubo zokulimala, ukuhlukaniswa kwe-AO, namasu okulungisa amapuleti e-distal humerus fractures ukusekela ukwelashwa okunembile komtholampilo.

1. I-Anatomy ye-Distal Humerus
I-distal humerus iqukethe amakholomu aphakathi nendawo, ahlanganisa ama-epicondyles nama-condyles.
2. Indlela Yokulimala
Ukuphuka kwe-distal humerus kubangelwa ukuhlukumezeka okuqondile (isb, ukuwa) noma amandla angaqondile (isb., ukusonteka noma ukudonsa kwemisipha).
3. Ukuhlelwa kwe-AO
Ukuhlukaniswa kwe-AO kuhlukanisa ukuhlukana kwe-distal humerus zibe izinhlobo ezintathu eziyinhloko: A , B , kanye no-C.
4. Ukwelashwa Ngokuhlinza
Ukwelashwa kokuhlinzwa kulandela izimiso ze-AO: ukuncishiswa kwe-anatomical, ukulungiswa okuzinzile, nokuvuselelwa kwangaphambi kwesikhathi.
5. Inani Lomtholampilo
Ama-locking plate inikeza ukuzinza okuphakeme kwe-biomechanical, ikakhulukazi kuthambo le-osteoporotic.
6. CZMEDITECH Amamodeli Amacwecwe
CZMEDITECH inikeza amamodeli amathathu: i-extraarticular (01.1107), i-lateral (5100-17), namapuleti aphakathi (5100-18).

I-Anatomy ye-Distal Humerus
I-distal humerus ihlukaniswe yaba yikholomu emaphakathi kanye nekholomu esemaceleni.
Ikholomu Emaphakathi
Ikholomu ephakathi ihlanganisa ingxenye ephakathi ye-metaphysis ye-humerus, i-epicondyle ephakathi, kanye ne-condyle ephakathi, kuhlanganise ne-trochlea ye-humerus.
Ikholomu Yangemuva
Ikholomu yangemuva ihlanganisa ingxenye esemaceleni ye-metaphysis ye-humerus, i-epicondyle ehlangene, ne-condyle ehlangene, kuhlanganise ne-capitulum ye-humerus.
I-Coronoid Fossa ne-Olecranon Fossa
Kutholwe phakathi kwamakholomu amabili i-anterior coronoid fossa kanye ne-posterior olecranon fossa.

Indlela Yokulimala Ekuqhekekeni Kwe-Distal Humerus
Kungani i-distal humerus ijwayele ukuphuka?
Njengengxenye ebalulekile yendololwane, ukuphuka kwe-distal humerus kuvame ukubangelwa 'ukuhlukumezeka okuqondile' (njengokuwa endololwaneni) noma 'ukuhlukumezeka okungaqondile' (okufana nokusonteka noma ukujikijela).
- Amandla Adonsa Imisipha
Ikholomu ephakathi ihlanganisa ingxenye ephakathi ye-metaphysis ye-humerus, i-epicondyle ephakathi, kanye ne-condyle ephakathi, kuhlanganise ne-trochlea ye-humerus.
·Ukufinyela okuqinile kwemisipha yangaphakathi ejikelezayo
·Ukufinyela okuqinile kwemisipha yokuguquguquka kwendololwane
- High-Energy Trauma
Amandla angaphandle njengezingozi zethrafikhi noma ukuwa ukusuka ekuphakameni kungaholela ekuqhekekeni okunciphile noma kuhilele indawo engaphezulu.
I-Coronoid Fossa ne-Olecranon Fossa
· Izingozi zomgwaqo
·Iwa ukusuka ekuphakameni

Ukuhlelwa Kwe-AO: Ukuthayipha Okunembile Ukuqondisa Izinqumo Zokuhlinza
Ngokohlelo lokuhlukaniswa kwe-AO, ukuhlukana kwe-distal humerus kuhlukaniswa kanjena, okunomthelela ngokuqondile ekukhethweni kwamasu okwelapha:
Uhlobo A: Ukuphuka kwe-articular eyengeziwe
- A1: Ukuphuka okulula, akukho ukubandakanyeka kwe-articular.
- A2/A3: Ukuphuka kwe-metaphyseal okunomthelela noma okususiwe, ukunakwa okudingekayo ngokukhubazeka kwe-angular.
Uhlobo B: Ukuphuka kwe-articular ingxenye
Umugqa wokuphuka uhilela indawo ehlangene kodwa ngaphandle kokuhlukana okuphelele; ukuncishiswa kwe-anatomical kuyadingeka ukuze kubuyiselwe ukuhambisana okuhlangene.
Uhlobo C: Qedela ukuphuka kwe-articular
- C1/C2: Ukuphuka okulula kwe-intra-articular ngokubandakanyeka kwe-metaphyseal.
- C3: Ukuphuka kwe-intra-articular, okuyinselele kakhulu ukukwelapha; ukulungiswa okuzinzile kuyadingeka ukuze kuncishiswe ingozi ye-post-traumatic arthritis.
Ukubaluleka Kokuhlukanisa:
Ukuhlukaniswa kwe-AO kucacisa ubukhali bokuphuka futhi kunikeza isiqondiso sokukhethwa kwepuleti (isb., amapuleti awodwa uma aqhathaniswa namakabili, amadizayini Isikulufu sokukhiya ) ukuze kuqinisekiswe kokubili amandla okulungisa kanye nebhalansi yezinto eziphilayo.

Ukwelashwa Kokuhlinzwa: Izinzuzo Eziyinhloko Zokulungiswa Kwe-Plate
Izimiso Zokwelashwa:
Ukulandela ifilosofi ye-AO: 'Ukunciphisa kwe-anatomical, ukulungiswa okuzinzile, nokuzivocavoca kwangaphambi kwesikhathi.'
I-High-Energy Trauma
Amandla angaphandle njengezingozi zethrafikhi noma ukuwa ukusuka ekuphakameni kungaholela ekuqhekekeni okunciphile noma kuhilele indawo engaphezulu.
Ukuncishiswa kwe-anatomical
Ukulungiswa okuzinzile
Ukuzivocavoca kokuqala kokusebenza
Izinkomba Zokuhlinza
Ukususwa kwe-Articular> 2mm
Vula ama-fracture
Ukulimala kwe-neurovascular okuhlanganisiwe
Ukwehluleka kokwelashwa okuvamile
I-Plate Fixation Strategie
I-Dual Plate Technique
Ifanele uhlobo C lokuphuka. Ukulungiswa kusuka kokubili okuphakathi (isb, i-anatomical I-locking plate ) kanye nezinhlangothi ze-lateral (isb, i-parallel plate) kunikeza ukuzinza kwe-3D futhi kunciphisa ingozi yokukhubazeka kokujikeleza kwangemva kokusebenza.
I-Single Plate Technique
Isetshenziselwa uhlobo A kanye nengxenye ye-B yokuphuka. Amapuleti enziwe ngaphambilini ahambisana ne-distal humerus anatomy anciphisa ukuhlukaniswa kwezicubu ezithambile.
Indlela Engenelela Kancane
Kuhlanganiswe nokubekwa kwesikulufu se-percutaneous ukunciphisa ingozi yokutheleleka kanye nokulondoloza ukutholakala kwegazi kwe-periosteal.

Inani Lomtholampilo Lokulungiswa Kwe-Plate
Inzuzo ye-Biomechanical
Ama-locking plate inikeza ukuzinza kwe-angular, okuzuzisa kakhulu iziguli ze-osteoporotic.
Isiqinisekiso Sokubuyisela Esisebenzayo
Ukwehliswa kwe-anatomical kulondoloza ukuhamba kwamalunga endololwane ngezinga elikhulu kakhulu, kunciphisa izinkinga ezifana nokungavumelani noma i-malunion.
Umklamo Owenziwe ngokwezifiso
Amapuleti amise okwezinhlobo ezithile zokuphuka (isb., amapuleti asekela ama-intercondylar ridge) akhulisa ukudluliswa kwamandla futhi asheshise ukuphola kwamathambo.
