Abakhiqizi Abaphezulu Abayi-10 e-America: I-Distal Humerus Locking Plates (May 2025)

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 engemuva ye-metaphysis ye-humerus, i-epicondyle ehlangene, kanye 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

I-distal humerus ihlukaniswe yaba yikholomu emaphakathi kanye nekholomu esemaceleni.

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 ImisiphaLateral Ikholomu

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 ·Ukufingqwa okuqinile kwemisipha enwebekayo yendololwane

- High-Energy Trauma

Amandla angaphandle njengezingozi zethrafikhi noma ukuwa ukusuka ekuphakameni kungaholela ekuqhekekeni okunciphile noma kuhilele indawo engaphezulu.

Ukuhlelwa Kwe-AO: Ukuthayipha Okunembile Ukuqondisa Izinqumo Zokuhlinza

Ngokohlelo lokuhlukaniswa kwe-AO, ukuhlukana kwe-distal humerus kuhlukaniswa ngale ndlela elandelayo, okuthonya ngokuqondile ukukhethwa 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.. Loc

Ukubaluleka Kokuhlukanisa:

Isigaba se-AO sicacisa ubukhali bokuphuka futhi sinikeza isiqondiso sokukhethwa kwepuleti (isb., amapuleti awodwa uma aqhathaniswa namakabili, imiklamo yezikulufu zokukhiya) 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.

Izimiso Zokwelapha

• 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., ipuleti lokukhiya le-anatomical) kanye nezinhlangothi ezingemuva (isb, ipuleti elihambisanayo) kunikeza ukuzinza kwe-3D futhi kunciphisa ingozi yokukhubazeka kokujikeleza kwangemva kokuhlinzwa.

• 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

Amapuleti okukhiya ahlinzeka ngokuzinza kwe-angular, enenzuzo ikakhulukazi ezigulini 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.
