Isingeniso sendlela yokuthola "i-radial nerve" endleleni engemuva eya ku-humerus

Ukwelashwa ngokuhlinzwa kokuphuka kwe-humerus ephakathi nendawo (njengalokho okubangelwa "ukulwa kwesandla") noma i-humeral osteomyelitis ngokuvamile kudinga ukusetshenziswa kwendlela eqondile engemuva esiya ku-humerus. Ingozi eyinhloko ehlotshaniswa nale ndlela ukulimala kwemizwa ye-radial. Ucwaningo lukhombisile ukuthi amathuba okulimala kwemizwa ye-radial ebangelwa indlela engemuva eya ku-humerus asukela ku-0% kuya ku-10%, kanti amathuba okulimala kwemizwa ye-radial okuhlala njalo asukela ku-0% kuya ku-3%.

Naphezu komqondo wokuphepha kwemizwa ye-radial, izifundo eziningi ziye zathembela ezibonelweni ezibonakalayo ze-anatomical njengesifunda se-supracondylar se-humerus noma i-scapula ukuze kubekwe indawo ngesikhathi sokuhlinzwa. Kodwa-ke, ukuthola imizwa ye-radial ngesikhathi senqubo kusalokhu kuyinselele futhi kuhlotshaniswa nokungaqiniseki okukhulu.

Umfanekiso wendawo yokuphepha kwemizwa ye-radial. Ibanga elimaphakathi ukusuka endizeni yemizwa ye-radial kuya ku-lateral condyle ye-humerus cishe liyi-12cm, kanti indawo yokuphepha idlula i-lateral condyle ngama-10cm.

Kulokhu, abanye abacwaningi bahlanganise izimo zangempela zangaphakathi kokuhlinzwa futhi balinganisa ibanga eliphakathi kwesihloko se-triceps tendon fascia kanye ne-radial nerve. Bathole ukuthi leli banga aliguquguquki futhi linenani eliphakeme lokuma phakathi kokuhlinzwa. Ikhanda elide le-triceps brachii muscle tendon ligijima cishe liqonde phezulu, kuyilapho ikhanda eliseceleni lakha i-arc ecishe ifane. Indawo yokuhlangana kwala ma-tendon yakha isihloko se-triceps tendon fascia. Ngokuthola amasentimitha angu-2.5 ngaphezu kwalesi sihloko, i-radial nerve ingabonakala.

 Indlela Yokubeka Indawo

Ngokusebenzisa ingxenye ephezulu ye-triceps tendon fascia njengereferensi, i-radial nerve ingatholakala ngokuhamba cishe ngamasentimitha angu-2.5 phezulu.

Ngocwaningo oluhilela isilinganiso seziguli ezingu-60, uma kuqhathaniswa nendlela yokuhlola yendabuko eyathatha imizuzu eyi-16, le ndlela yokubeka isiguli endaweni ethile yanciphisa isikhathi sokusikwa kwesikhumba saya esikhathini sokuchayeka emithanjeni ye-radial saba yimizuzu eyi-6. Ngaphezu kwalokho, igweme ngempumelelo ukulimala kwemithambo ye-radial.

Ukulungiswa kwesithombe se-macroscopic ngaphakathi kokuhlinzwa sokuphuka kwe-humeral okuphakathi nendawo okungu-1/3. Ngokubeka ama-suture amabili angena emzimbeni ahlangana cishe no-2.5cm ngaphezu kwendawo ye-triceps tendon fascia apex, ukuhlola ngale ndawo yokuhlangana kuvumela ukuvezwa kwe-radial nerve kanye ne-vascular bundle.
Ibanga okukhulunywe ngalo lihlobene ngempela nokuphakama kwesiguli kanye nobude bengalo. Uma kusetshenziswa ngendlela engokoqobo, lingalungiswa kancane ngokusekelwe emzimbeni wesiguli kanye nobukhulu bomzimba waso.
