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
Kukiya mahwendefa anopa yepamusoro 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.
Sei iyo distal humerus inowanzoita kuputsika?
Sechikamu chakakosha chejoint yegokora, distal humerus fractures inowanzobva ku 'direct trauma' (sekudonha kudonhera pagokora) kana 'indirect trauma' (sekumonyorora kana kukanda zviito).
- Tsandanyama Dhonza Masimba
Mutsara wepakati unosanganisira chikamu chemukati metaphysis yehumerus, epicondyle yemukati, uye condyle yemukati, kusanganisira 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.
Coronoid Fossa uye Olecranon Fossa
· Tsaona dzemumugwagwa
·Kudonha kubva pakakwirira
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.
Kurapa Misimboti
Anatomical kuderedza
Kugadziriswa kwakagadzikana
Early functional exercise
Kuvhiya Zviratidzo
Articular displacement> 2mm
Vhura mafractures
Yakasanganiswa neurovascular kukuvara
Kukundikana kwekuchengetedza kurapa
Plate Fixation Strategie
Dual Plate Technique
Inokodzera mhando C fractures. Kugadziriswa kubva kune ese ari maviri emukati (semuenzaniso, anatomical locking plate) uye lateral (semuenzaniso, parallel plate) mativi anopa 3D kugadzikana uye inoderedza njodzi yekumashure kwekuita kutenderera kutenderera.
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.
Biomechanical Advantage
Kukiya mahwendefa anopa kugadzikana kweangular, kunyanya kubatsira kune varwere vane osteoporotic.
Functional Recovery Guarantee
Anatomical reduction inochengetedza kufamba kwegokora kusvika pamwero mukuru, kuderedza matambudziko akadai seasina kubatanidzwa kana malunion.
Customized Design
Mahwendefa akaumbwa emhando dzakasiyana dzekutyoka (semuenzaniso, intercondylar ridge support plates) anonatsiridza kutapurirana kwesimba uye nekuchimbidza kupora kwemapfupa.
Yedu distal humerus yekuvhara ndiro yakatevedzana yakanyatsogadzirirwa yakaoma distal humeral fractures. Iine anatomical contouring, kukiya screw tekinoroji, uye akawanda maratidziro, inopa yakachengeteka, yakagadzikana, uye inochinjika kugadzirisa mhinduro dzekuvhiyiwa kwekiriniki.
