Executive Summary
Ichi chidzidzo chekiriniki chinopa vaviri vanomiririra varwere vakura vane yakaoma proximal humeral fractures inogadziriswa kushandisa XC Medico's intramedullary nail systems . Vaviri varwere vakawana kuderedzwa kweanatomic, mubatanidzwa wakasimba, uye yakanakisa kupora kupora kunyangwe yakakosha osteoporosis uye kutsemuka kwakaoma.
Key Clinical Zvakawanikwa:
- ✓ Intramedullary nailing inopa yakakwirira biomechanical kugadzikana mune osteoporotic bone kana ichienzaniswa neplate fixation.
- ✓ Maitiro ekupinda zvishoma anoderedza kukuvara kwetishu uye nguva yekushanda ne25-30%
- ✓ Kugovera-kugovera dhizaini yeIM zvipikiri inobvumira kuunganidza kwekutanga pasina kukanganisa kuporeswa kwekutyoka
- ✓ Zvibodzwa zvemakore maviri (Constant-Murley zvibodzwa 62-64) zvinoratidza kusimba uye kugutsikana kwemurwere.
Kuvhiya Technique Nhanganyaya
Ne intramedullary (IM) nailing kuwana kugamuchirwa kweproximal humeral fractures, kunzwisisa kwakakodzera nzira yekuvhiya kwakakosha[cite: 6]. Kusiyana neplate fixation, IM misumari inoshanda semidziyo yekugovanisa zvinhu , zvichireva kuti kugadzikana hakunei nekutenga sikuruu muosteoporotic bone[cite: 5]. Uyu mutsauko wakakosha unoita IM kuroverera zvakanyanya kubatsira muvarwere vakura vane hutsinye hwemapfupa [cite: 4].
Mazano Anokosha Ounyanzvi
- Anatomic Reduction: Kudzoreredza iyo chaiyo musoro-shaft angle uye kudzivirira varus kutama kwakakosha [cite: 4]
- Medial Kugadzikana: Iyo yepakati hinge inofanirwa kudzoserwa kudzivirira varus angulation [cite: 4]
- Kugadziriswa-Kugovera Kugadziriswa: IM zvipikiri zvinopa kugadzikana nekukurumidza pasina kuda biological fusion [cite: 5]
- Minimally Invasive Approach: Inoderedza kupfava kwetishu uye nguva yekushanda ichienzaniswa neyakavhurika plate fixation [cite: 4]
Mune osteoporotic bone, IM nailing yakaratidza hukuru hwebiomechanical [cite: 5]. Kugadzirisa-kugovera kugadzirisa kunobvumira mbambo pachayo kuti ipe kugadzikana uku ichisimudzira callus kuumbwa [cite: 5]. Izvi zvinopesana neplate fixation, iyo inotakura-inotakura uye inogona kutungamirira kune kushungurudzika-kudzivirira.
Kuvhiya Nzira uye Nzvimbo Yekupinda
Iyo deltoid-kupatsanura nzira inopa yakanakisa kuratidzwa uku ichideredza rotator cuff kukuvara [cite: 10]. Kana kuputsika kuchingoonekwa, kuderedzwa kweanatomic kunowanikwa uchishandisa fluoroscopic kutungamira uye nzira dzekudzikisa mufaro.
Medullary Canal Kugadzirira
Nzvimbo yekupinda yakakosha[cite: 8]. Yakamisikidzwa yepakati kune iyo supraspinous fossa uye inoenderana neiyo humeral shaft, inova nechokwadi chekwakaringana chipikiri trajectory [cite: 10]. Waya yekutungamira inozofambiswa mberi kuburikidza nemugero wehumeral, uye sequential reaming inoitwa kugadzirira mugero wekuisirwa kuiswa [cite: 10].

Preoperative Imaging
Rosa María akaunzwa neHertel ina-chikamu proximal humeral fracture inoratidzwa ne[cite: 21]:
- Kutama kwakazara kwehumeral musoro ine varus angulation (18 ° kubva kuanatomic axis) [cite: 20, 21]
- Yakakura tuberosity displacement> 10mm
- Kuendeswa kwekuvhiya mutsipa nharaunda
- Yakanyanya osteoporotic bone quality (BMD 58 HU)
Intramedullary Nail Fixation
Chigadzirwa Chinoshandiswa: XC Medico Multi-Lock Humerus Intramedullary Nail System
Tichipihwa yakanyanya osteoporosis uye mana-chikamu kutsemuka pateni, IM chipikiri kugadzirisa yakasarudzwa pamusoro pekugadzirisa ndiro nekuti[cite: 23]:
- Simba rekudhonza screw mu58 HU bone ingori 250-350 N ine plate fixation, maringe ne600-800 N ine simende-yakawedzera IM kuroverera.
- Mutoro-kugovera dhizaini inosimudzira kuporeswa kwekutyoka muurombo-mhando bhonzo [cite: 5]
- Minimally invasive nzira inoderedza nguva yekushanda ne30-40 maminetsi [cite: 4]
- Multi-planar proximal locking inogovera mitoro kumativi matatu-dimensional cage chimiro [cite: 8]
