Distal humerus fractures ke mofuta o tloaelehileng oa kotsi e matla ea matla ho masapo a masapo. Bothata ba phekolo bo itšetlehile ka ho rarahana ha sebopeho sa anatomical le tlhokahalo ea ho tsosolosa mosebetsi o kopanetsoeng. Joaloka mofani oa tharollo ea setsebi lefapheng la ho lokisa masapo a ka hare, re fana ka tlhahlobo e tebileng ea mekhoa ea likotsi, AO classification, le mekhoa ea ho lokisa lipoleiti bakeng sa fractures ea distal humerus ho tšehetsa phekolo e nepahetseng ea kliniki.
1. Anatomy ea Distal Humerus
The distal humerus e na le litšiea tse bohareng le tse ka morao, tse kenyelletsang li-epicondyles le li-condyles.
2. Mokhoa oa Kotsi
Ho robeha ha distal humerus ho bakoa ke ts'oaetso e tobileng (mohlala, ho oa) kapa matla a sa tobang (mohlala, ho sotha kapa ho hula mesifa).
3. AO Classification
AO classification e arola distal humerus fractures ka mefuta e meraro e meholo: A , B , le C .
4. Kalafo ea Opereishene
Kalafo ea ho buuoa e latela melao-motheo ea AO: ho fokotseha ha anatomical, ho lokisoa ho tsitsitseng, le ho tsosolosoa pele.
5. Boleng ba Clinical
Locking plates fana ka botsitso bo phahameng ba biomechanical, haholo-holo ho osteoporotic bone.
6. CZMEDITECH Mehlala ea Plate
CZMEDITECH e fana ka mefuta e meraro: extraarticular (01.1107), lateral (5100-17), le lipoleiti tsa medial (5100-18).
Anatomy ea Distal Humerus
The distal humerus e arotsoe ka kholomo e bohareng le kholomo ea lateral.
Kholomo e Bohareng
Karolo e bohareng e kenyelletsa karolo e bohareng ea metaphysis ea humerus, epicondyle e bohareng, le condyle e bohareng, ho kenyelletsa le trochlea ea humerus.
Kholo ea ka morao
Karolo ea lateral e kenyelletsa karolo ea lateral ea metaphysis ea humerus, epicondyle ea lateral, le lateral condyle, ho akarelletsa le capitulum ea humerus.
Coronoid Fossa le Olecranon Fossa
Lipakeng tsa litšiea tse peli ke karolo e ka pele ea coronoid fossa le posterior olecranon fossa.
Mokhoa oa Kotsi ho Distal Humerus Fractures
Ke hobane'ng ha humerus ea distal e atisa ho robeha?
E le karolo ea bohlokoa ea lenonyeletso la setsoe, ho robeha ha distal humerus hangata ho bakoa ke 'trauma e tobileng' (e kang ho oela holim'a setsoe) kapa 'ts'oaetso e sa tobang' (e kang ho sotha kapa ho lahla).
- Mesifa e Hulang Mabotho
Karolo e bohareng e kenyelletsa karolo e bohareng ea metaphysis ea humerus, epicondyle e bohareng, le condyle e bohareng, ho kenyelletsa le trochlea ea humerus.
· Ho kopana ho matla ha mesifa ea ka hare ea rotator
·Ho honyela ho matla ha mesifa ea setsoe ea flexor
- Tlokotsi ea Matla a Phahameng
Matla a kantle joalo ka likotsi tsa sephethephethe kapa ho oa ho tloha bophahamong ho ka baka ho robeha ho sa feleng kapa ho kenyelletsa bokaholimo ba marang-rang.
Coronoid Fossa le Olecranon Fossa
· Likotsi tsa sephethephethe
·Ho oela ho tloha bophahamong
AO Classification: Mongolo o Nepahetseng ho Tataisa Liqeto tsa ho Buoa
Ho latela sistimi ea AO, fractures ea distal humerus e arotsoe ka tsela e latelang, e amang khetho ea maano a kalafo ka kotloloho:
Mofuta oa A: Ho robeha ho eketsehileng
- A1: Ho robeha ho bonolo, ha ho na karolo ea articular.
- A2 / A3: Ho robeha ha metaphyseal ho amehang kapa ho fallisitsoeng, tlhokomelo e hlokahalang bakeng sa bokooa ba angular.
Mofuta oa B: Ho robeha ha karolo e itseng ea articular
Mohala oa ho robeha o kenyelletsa bokaholimo bo kopaneng empa ntle le karohano e felletseng; phokotso ea anatomical ho hlokahala ho tsosolosa kopanelo conngruency.
Mofuta oa C: Ho robeha ho feletseng ha articular
- C1 / C2: Ho robeha habonolo ha intra-articular ka ho kenya letsoho ha metaphyseal.
- C3: Li-fractures tsa intra-articular, tse thata ka ho fetisisa ho li phekola; ho lokisoa ho tsitsitseng hoa hlokahala ho fokotsa kotsi ea ramatiki ea morao-rao.
Bohlokoa ba Khethollo:
Sehlopha sa AO se hlakisa ho teba ha ho robeha 'me se fana ka tataiso bakeng sa khetho ea poleiti (mohlala, lipoleiti tse le 'ngoe le tse peli, Sekurufu se notlelang meralo) ho netefatsa matla a ho lokisa le ho leka-lekana ha likokoana-hloko.
Phekolo ea ho Buoa: Melemo ea Bohareng ea Plate Fixation
Melao-motheo ea Kalafo:
Ho latela filosofi ea AO: 'Phokotso ea anatomical, fixation e tsitsitseng, le boikoetliso ba pele ba ts'ebetso.'
Tlokotsi ea Matla a Phahameng
Matla a kantle joalo ka likotsi tsa sephethephethe kapa ho oa ho tloha bophahamong ho ka baka ho robeha ho sa feleng kapa ho kenyelletsa bokaholimo ba marang-rang.
Melao-motheo ea Kalafo
Phokotso ea anatomical
Ho lokisa ho tsitsitseng
Boikoetliso ba pele bo sebetsang
Lipontšo Tsa ho Buoa

Plate Fixation Strategie
Theknoloji ea lipoleiti tse peli
E loketse mofuta oa C fractures. Ho lokisoa ho tloha mahlakoreng a mabeli a mahareng (mohlala, anatomical Locking plate ) le lateral (mohlala, parallel plate) mahlakoreng a fana ka botsitso ba 3D le ho fokotsa kotsi ea ho senyeha ha potoloho ka mor'a ho sebetsa.
Mokhoa o le mong oa Plate
E sebelisoa bakeng sa fractures ea mofuta oa A le mofuta oa B. Lipoleiti tse entsoeng esale pele tse lumellanang le distal humerus anatomy li fokotsa ho arohana ha lisele tse bonolo.
Mokhoa o sa Hlaseheng Hanyenyane
E kopantsoe le percutaneous screw placement ho fokotsa kotsi ea tšoaetso le ho boloka phepelo ea mali ea periosteal.
Bohlokoa ba Kliniki ea ho Lokisoa ha Plate
Molemo oa Biomechanical
Locking plates fana ka botsitso ba angular, haholo-holo ho molemo ho bakuli ba osteoporotic.
Tiisetso ea Ts'ebetso ea Ts'ebetso
Phokotso ea anatomical e boloka ho sisinyeha ha manonyeletso a setsoe ka mokhoa o fetisisang, ho fokotsa mathata a kang ho se kopane kapa malunion.
Moralo o ikhethileng
Lipoleiti tse entsoeng bakeng sa mefuta e itseng ea ho robeha (mohlala, lipoleiti tsa li-intercondylar ridge support) li matlafatsa phetiso ea matla le ho potlakisa ho fola ha masapo.
