Vagadziri vepamusoro gumi muAmerica: Distal Humerus Locking Plates ( Chivabvu 2025)

Anatomy yeDistal Humerus

Iyo distal humerus yakakamurwa kuita yepakati column uye lateral column.

Medial Column

Mutsara wepakati unosanganisira chikamu chemukati metaphysis yehumerus, epicondyle yemukati, uye condyle yemukati, kusanganisira 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

Iyo distal humerus yakakamurwa kuita yepakati column uye lateral column.

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).

AO Classification: Yakarurama Typing Kutungamira Kuvhiya Sarudzo

Zvinoenderana neiyo AO classification system, distal humerus fractures yakarongedzerwa sezvizvi, zvichipesvedzera zvakananga kusarudzwa kwemaitiro ekurapa:

Rudzi rweA: Kuwedzera-articular fractures

- A1: Kutsemuka kuri nyore, hapana kubatanidzwa kwekutaura. - 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 dambudziko rekurwadziwa kwearthritis.. Loc

Kukosha Kwekuronga:

The AO classification inojekesa kuoma kwekutyoka uye inopa nhungamiro yekusarudza ndiro (semuenzaniso, single vs. dual plates, locking screw designs) kuti ive 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.

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.

Clinical Value yePlate Fixation

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.
