1. Anatomy ea Distal Humerus
The distal humerus e na le litšiea tse bohareng le tse ka morao, tse kenyeletsang 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. Bohlokoa ba Clinical
Lipoleiti tse notlelang li fana ka botsitso bo phahameng ba biomechanical, haholo-holo ho osteoporotic bone.
6. CZMEDITECH Plate Models
CZMEDITECH e fana ka mefuta e meraro: extraarticular (01.1107), lateral (5100-17), le lipoleiti tsa medial (5100-18).
Ke hobane'ng ha humerus ea distal e atisa ho robeha?
E le karolo ea bohlokoa ea lenonyeletso la setsoe, hangata ho robeha ha humerus hangata ho bakoa ke 'ts'oaetso e tobileng' (joalo ka ho oela ka setsoe) kapa 'ts'oaetso e sa tobang' (e kang ho sotha kapa ho lahla).

Plate Fixation Strategie
Theknoloji ea lipoleiti tse peli
E loketse mofuta oa C fractures. Ho lokisa ho tloha mahlakoreng a mabeli a bohareng (mohlala, poleiti ea ho notlela ea anatomical) le mahlakoreng a mahlakoreng a mabeli (mohlala, parallel plate) e 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.
Molemo oa Biomechanical
Lipoleiti tsa ho notlela li 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.

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.

Ka theknoloji ea 'anatomical contouring', 'screw screw technology', le litlhaloso tse ngata, e fana ka litharollo tse bolokehileng, tse tsitsitseng le tse bonolo bakeng sa opereishene ea bongaka.
