Ọnọdụ na nkwadebe tupu ịwa ahụ: Otu dị ka ọ dị na mbụ.
Usoro ịwa ahụ:
Ebe nchekwa maka itinye K-waya n'akụkụ azụ nke radius dị anya bụ: n'akụkụ abụọ nke tubercle Lister, n'akụkụ abụọ nke akwara extensor pollicis longus, na n'etiti eriri eriri digitorum communis extensor na eriri mkpịsị digiti minimi.
N'otu ụzọ ahụ, a na-etinye screws Schanz abụọ na radial shaft ma jikọta ya na mkpanaka njikọ.
Site na mpaghara nchekwa ahụ, a na-etinye screws Schanz abụọ n'ime iberibe mgbawa radius dị anya, otu site na akụkụ radial na otu site na azụ azụ, na akụkụ nke 60 ° ruo 90 ° na ibe ya.Ihe nkedo ahụ kwesịrị ijide cortex contralateral, ma ekwesịrị ịmara na ọnụ nke ịghasa nke etinyere n'akụkụ radial enweghị ike ịgafe na sigmoid notch wee banye na nkwonkwo redioulnar distal.
Jikọọ ihe nkedo Schanz na radius dị anya na njikọ gbagọrọ agbagọ.
Jiri mkpanaka njikọ etiti jikọọ akụkụ abụọ ndị gbajiri agbaji, ma kpachara anya ka ị ghara igbachi mkpọ ahụ nwa oge.Site n'enyemaka nke njikọ dị n'etiti, a na-ebelata nkebi dị anya.
Mgbe ịtọgharịa, kpọchie chack na mkpanaka njikọ iji mezue ikpeazụndozi.
Ọdịiche dị n'etiti onye na-ahụ maka mpụga na-abụghị nke jikọrọ ọnụ na onye na-eme ihe na-agafe agafe:
N'ihi na enwere ike itinye ọtụtụ screws Schanz iji mechaa mbelata na nhazi nke ọkpụkpụ ọkpụkpụ, ihe ngosi ịwa ahụ maka ndị na-emepụta ihe na-abụghị ndị na-emepụta ihe na-eme ka ndị na-emepụta ihe na-eme ka ndị na-emepụta ihe na-agafe agafe.Na mgbakwunye na mgbaji ọkpụkpụ nke ọzọ, a pụkwara iji ha mee ihe maka mgbaji nke abụọ ruo nke atọ.Ihe mgbawa n'ime akụkụ akụkụ.
Onye na-edozi ihe na-agafe agafe na-edozi nkwonkwo nkwojiaka na-adịghị ekwe ka mmega ahụ na-arụ ọrụ n'oge, ebe onye na-abụghị cross-njikọ mpụga na-enye ohere mgbatị nkwonkwo nkwonkwo n'oge mgbe ọ gasịrị.
