Maonero: 0 Munyori: Saiti Edhita Nguva Yekuburitsa: 2025-05-22 Mavambo: Site
Distal humerus fractures imhando yakajairika yekukuvara kwepamusoro-simba mune orthopedics. Kuoma mukurapa kunowanikwa mukuoma kwechimiro cheanatomical uye chido chekudzorera basa rekubatana. Semupi wezvekugadzirisa mhinduro mumunda we orthopedic internal fixation, tinopa kuongorora kwakadzama kwemaitiro ekukuvadza, AO kupatsanurwa, uye nzira dzekugadzirisa ndiro dze distal humerus fractures kuti itsigire kurapwa kwekliniki chaiyo.
1. Anatomy yeDistal Humerus Iyo distal humerus inoumbwa nepakati uye lateral columns, iyo inosanganisira epicondyles uye condyles.
2. Nzira yeKukuvadza Distal humerus fractures inokonzerwa nekukuvara kwakananga (semuenzaniso, kudonha) kana masimba asina kunanga (semuenzaniso, kumonyoroka kana kudhonza tsandanyama).
3. AO Classification The AO classification inokamura distal humerus fractures mumhando nhatu huru: A , B , uye C .
4. Kuvhiya Kurapa Kurapa kwekuvhiya kunotevera misimboti yeAO: kuderedzwa kweanatomical, kugadzirisa kwakagadzikana, uye kugadziridza kwekutanga.
5. Kukosha Kwechipatara Locking plates inopa yakakwirira biomechanical kugadzikana, kunyanya mune osteoporotic bone.
6. CZMEDITECH Plate Models CZMEDITECH inopa mhando nhatu: extraarticular (01.1107), lateral (5100-17), uye medial (5100-18) mahwendefa.
Anatomy yeDistal Humerus
Iyo distal humerus yakakamurwa kuita yepakati column uye lateral column.
Medial Column Mutsara wepakati unosanganisira chikamu chemukati metaphysis yehumerus, iyo medial epicondyle, uye medial condyle, kusanganisira iyo trochlea yehumerus.
Lateral Column Iyo lateral column inosanganisira lateral chikamu che metaphysis yehumerus, iyo lateral epicondyle, uye lateral condyle, kusanganisira capitulum yehumerus.
Coronoid Fossa uye Olecranon Fossa Iri pakati pemakoramu maviri pane anterior coronoid fossa uye posterior olecranon fossa.
Mechanism yeKukuvadza muDistal Humerus Fractures
Sei iyo distal humerus inowanzoita kuputsika? Sechikamu chakakosha chejoint yegokora, distal humerus fractures inowanzobva kune 'direct trauma' (sekudonha kudonhera pagokora) kana 'indirect trauma' (sekumonyorora kana kukanda zviito).
- Tsandanyama Dhonza Masimba Mutsara wepakati unosanganisira chikamu chemukati metaphysis yehumerus, iyo medial epicondyle, uye medial condyle, kusanganisira iyo trochlea yehumerus.
·Kubatana kwakasimba kwemukati rotator tsandanyama
·Kudhonzwa kwakasimba kwemhasuru dzegokora
- High-Energy Trauma Masimba ekunze akadai mutsaona dzemotokari kana kudonha kubva pakakwirira zvinogona kuguma nekutyoka kwakapetwa kana kubatanidza nzvimbo yearticular.

AO Classification: Yakarurama Typing Kutungamira Kuvhiya Sarudzo
Zvinoenderana neiyo AO classification system, distal humerus fractures yakakamurwa seizvi, ichipesvedzera zvakananga kusarudzwa kwemaitiro ekurapa:
Rudzi rweA: Kuwedzera-articular fractures - A1: Kutyoka kuri nyore, hapana kubatanidzwa.
- A2 / A3: Yakakanganiswa kana yakadzingwa metaphyseal fractures, kutarisisa kunodiwa kune angular deformities.
Rudzi B: Chikamu che articular fractures Mutsara wekuputsika unosanganisira nzvimbo yakabatana asi pasina kuparadzaniswa kwakakwana; anatomical kuderedza kunofanirwa kudzoreredza kubatana kwekubatana.
Rudzi C: Yakazara articular fractures - C1 / C2: Nyore intra-articular fractures ine metaphyseal kubatanidzwa.
- C3: Yakagadzirirwa intra-articular fractures, yakanyanya kuoma kurapa; kugadziriswa kwakasimba kunodiwa kuderedza njodzi yepost-traumatic arthritis.
Kukosha Kwekuronga: IAO classification inojekesa kuoma kwekuputsika uye inopa hutungamiri hwekusarudzwa kweplate (somuenzaniso, single vs. dual plates, Siruu yekukiya magadzirirwo) kuti ave nechokwadi chekugadzirisa simba uye biological balance.
Kuvhiya Kurapa: Core Kubatsira kwePlate Fixation
Kurapa Misimboti: Kutevera huzivi hweAO: 'Kuderedzwa kweAnatomical, kugadzirisa kwakadzikama, uye kurovedza muviri kwekutanga.'
High-Energy Trauma Masimba ekunze akadai mutsaona dzemotokari kana kudonha kubva pakakwirira zvinogona kuguma nekutyoka kwakapetwa kana kubatanidza nzvimbo yearticular.

Plate Fixation Strategie
Dual Plate Technique Inokodzera mhando C fractures. Kugadziriswa kubva kune zvose zviri mukati (semuenzaniso, anatomical Locking plate ) uye lateral (eg, parallel plate) mativi anopa 3D kugadzikana uye kunoderedza ngozi ye postoperative rotational deformity.
Single Plate Technique Inoshandiswa kune mhando A uye chikamu chemhando B mafractures. Pre-contoured plates inoenderana ne distal humerus anatomy inoderedza kupfava kwenyama dissection.
Minimally Invasive Approach Yakasanganiswa nepercutaneous screw placement kuderedza njodzi yehutachiona uye kuchengetedza periosteal ropa.
Clinical Value yePlate Fixation
Biomechanical Advantage Locking plates inopa kugadzikana kweangular, kunyanya inobatsira kune varwere vane osteoporotic.
Functional Recovery Guarantee Anatomical reduction inochengetedza magokora akabatana kufamba kusvika pamwero mukuru, kuderedza matambudziko akadai seasina nonunion kana malunion.
Customized Design Mahwendefa akaumbwa emhando dzakasiyana dzekutyoka (semuenzaniso, intercondylar ridge support plates) anonatsiridza kutapurirana kwesimba uye nekuchimbidza kupora kwemapfupa.
