I.N'ihi gịnị ka cannulated ịghasa nwere oghere?
Kedu ka sistemu screw cannulated si arụ ọrụ? Iji obere Kirschner wires (K-wires) nke agbabaworo n'ime ọkpụkpụ iji duzie trajectories nke ọma n'ime obere iberibe ọkpụkpụ.
Iji K-wires na-ezere ịkwanye oghere ndị na-anya ụgbọ elu ma na-enye ohere idozi iberibe ọkpụkpụ dị nso n'oge ntinye screw. A na-etinye ngwaọrụ oghere na skru oghere n'ime ọkpụkpụ n'elu waya K. Ndozi ihe nkedo nke cannulated bara uru na spain cervical iji mee ka ọkpụkpụ odontoid kwụsie ike na iji gwọọ nsogbu nke atlantoaxial.
Ihe nkedo nke cannulated nwere ọtụtụ uru ma e jiri ya tụnyere skru na-enweghị ike: 1) K-wires na-eduzi ọnọdụ ịghasa n'ime ọkpụkpụ;
2) trajectory K-waya na-eme ka ọ dị mfe ma ọ bụrụ na trajectory mbụ adịghị mma;
3) na K-wires na-enye ohere na-aga n'ihu na-edozi iberibe ọkpụkpụ na-adịghị akwụsi ike n'akụkụ;
4) K-wires na-egbochi mmegharị nke iberibe ọkpụkpụ na-adịghị akwụ ụgwọ n'oge ntinye nke ịghasa.
Enwere ike ibelata ihe mgbagwoju anya metụtara waya K (njiji, ndogharị, na ọganihu) site na iji usoro ịwa ahụ. Emepụtara sistemu ihe mgbịrịgba skru pụrụ iche maka ndozi cervical dị elu iji kwe ka mgwupu ala site na iji ngwaọrụ ọwara ogologo, n'ọbọ anụ ahụ, ntụzịaka olulu na ogologo K-wires. Ngwá ọrụ ndị a na-enye ohere ịnye skru cannulated n'akụkụ dị ala n'ọkpụkpụ azụ site na trajectories anụ ahụ dị nro dị ogologo. Mkpọsa mkpọ nwere uru dị ukwuu ma e jiri ya tụnyere skru na-enweghị mkpọ maka ndozi nke spain cervical na-akwụghị ụgwọ na sistemu.
II. Kedu nke ka mma cannulated kposara ma ọ bụ intrameduallary mbọ?
Ma mbọ intramedullary na mbọ cannulated bụ ngwaọrụ ahụike eji emezi n'ime ime mgbaji. Ha nke ọ bụla nwere uru nke ya ma dabara maka ụdị mgbaji dị iche iche na mkpa ọgwụgwọ.
| Ụdị | Uru |
| Ntu intramedullary | Mmetụta ntu ntu intramedullary na mgbaji siri ike nke ọkpụkpụ dị ogologo dị mma, na-enwe obere mmerụ ahụ yana obere ọbara ọgbụgba. Ntuzi ntu intramedullary bụ nke nhazi etiti. E jiri ya tụnyere efere ígwè, ntu intramedullary nwekwara ike ichekwa iguzosi ike n'ezi ihe nke akpụkpọ ahụ na-adịghị ahụkebe, gbochie ọgwụgwọ mgbaji na-egbu oge, ma na-ekere òkè n'izere ọrịa. |
| Mkpọsa akpọnwụ akpọnwụ | A na-etinyekarị ya na mpaghara ndị dị ka mgbaji n'olu femoral, nwere nhazi pụrụ iche na mkpakọ mmetụta. Ọzọkwa, mmebi ahụ dị ntakịrị ma ọ dịghị efere ígwè ọ bụla achọrọ. |
III. Kedu mgbe a ga-eji skru kagbuo vs cortical?
Ihe nkedo nke kagbuo na skru cortical bụ ụdị abụọ nke ọkpụkpụ orthopedic a na-eji na-edozi ọkpụkpụ, ma e mere ha maka ụdị ọkpụkpụ dị iche iche ma nwee ngwa dị iche iche:
Cancellous kposara na-kpọmkwem e mere maka ojiji na spongy, obere ok, na trabecular ọkpụkpụ anụ ahụ, nke a na-ahụkarị na nsọtụ nke ogologo ọkpụkpụ, dị ka femur na tibia.A na-eji na ebe ọkpụkpụ bụ ihe porous na obere ok, dị ka metaphyseal mpaghara nke ogologo ọkpụkpụ. A na-ejikarị ha eme ihe na usoro metụtara ọkpụkpụ azụ, pelvis, na akụkụ ụfọdụ nke ubu na hip.
A haziri skru cortical maka ojiji na nnukwu ọkpụkpụ, ọkpụkpụ cortical, nke na-etolite oyi akwa nke ọtụtụ ọkpụkpụ ma sie ike ma sie ike karịa ọkpụkpụ ịkagbu. A na-ejikarị eme ihe n'ọnọdụ ebe a chọrọ ike na nkwụsi ike ka ukwuu, dị ka na nhazi nke mgbaji na diaphysis (osisi) nke ọkpụkpụ ogologo. A na-ejikwa ha na ụfọdụ ngwaọrụ ndozi ime na efere.
Na nchịkọta, nhọrọ n'etiti ịkagbu na skru cortical na-adabere n'ụdị ọkpụkpụ a na-edozi na ihe ndị dị mkpa nke usoro orthopedic. Ihe nkedo nke kagbuo dabara adaba maka ọkpụkpụ dị nro, nke na-agbapụta agbaze, ebe skru cortical dị mma maka ọkpụkpụ na-ebu ibu.
