Ọkpụkpụ nke isi radial na olu radial bụ mgbaji nkwonkwo nkwonkwo nkwonkwo, na-esitekarị na ike axial ma ọ bụ nrụgide valgus.Mgbe nkwonkwo ikpere ụkwụ nọ n'ọnọdụ dị ogologo, 60% nke ike axial na aka aka na-ebufe ya nso site na isi radial.Na-esochi mmerụ ahụ n'isi radial ma ọ bụ olu radial n'ihi ike, ndị agha ịkwa osisi nwere ike imetụta capitulum nke humerus, nke nwere ike ibute ọkpụkpụ na ọkpụkpụ cartilage.
Na 2016, Claessen chọpụtara otu ụdị mmerụ ahụ ebe mgbaji nke isi / olu radial na-esonyere ọkpụkpụ / cartilage mebiri na capitulum nke humerus.Akpọrọ ọnọdụ a “ọnya nsusu ọnụ,” ya na mgbaji gbajiri agbaji nke gụnyere nchikota a nke a na-akpọ “njiji nsusu ọnụ.”Na akụkọ ha, ha gụnyere ikpe iri nke nsusu ọnụ ma chọpụta na ikpe 9 nwere mgbaji isi radial nkewapụtara dị ka ụdị Mason II.Nke a na-egosi na site n'ụdị mgbawa isi radial nke Mason II, ekwesịrị inwewanye mmata maka mgbaji nke capitulum nke humerus nwere ike iso.
N'ihe omume ụlọọgwụ, mgbaji nsusu ọnụ na-adịkarị mfe nchọpụta ezighi ezi, ọkachasị n'ọnọdụ ebe enwere nnukwu ngbanwe nke mgbawa isi/olu radial.Nke a nwere ike bute ileghara mmerụ ahụ metụtara anya na capitulum nke humerus.Iji nyochaa njirimara ụlọ ọgwụ na ọnụọgụ nke nsusu ọnụ, ndị nchọpụta si mba ọzọ mere nyocha nke ọnụ ọgụgụ buru ibu na 2022. Nsonaazụ bụ ndị a:
Ọmụmụ ihe ahụ gụnyere ngụkọta nke ndị ọrịa 101 nwere mgbawa isi / olu radial bụ ndị a na-emeso n'etiti 2017 na 2020. Dabere na ma ha nwere mgbaji jikọtara nke capitulum nke humerus n'otu akụkụ, e kewara ndị ọrịa ahụ ụzọ abụọ: otu capitulum (Group I) na otu na-abụghị capitulum (Group II).
Ọzọkwa, a na-enyocha mgbawa isi nke radial dabere na ọnọdụ ha, nke kewara na mpaghara atọ.Nke mbụ bụ mpaghara nchekwa, nke abụọ bụ mpaghara etiti etiti, na nke atọ bụ mpaghara etiti azụ.
Nsonaazụ ọmụmụ ahụ gosipụtara nchoputa ndị a:
- Ka ọkwa Mason dị elu nke mgbaji isi radial, ka ọ na-enwekarị ihe ize ndụ nke iso mgbaji capitulum.Ihe gbasara nke puru omume nke ụdị Mason I radial isi mgbaji jikọtara ya na mgbawa capitulum bụ 9.5% (6/63);maka ụdị Mason II, ọ bụ 25% (6/24);na maka ụdị Mason III, ọ bụ 41.7% (5/12).
- Mgbe mgbawa isi radial gbatịpụrụ ka ọ tinye aka n'olu radial, ihe ize ndụ nke mgbaji capitulum belatara.Akwụkwọ ndị ahụ akọwapụtaghị ihe ọ bụla dịpụrụ adịpụ nke mgbawa n'olu radial na-ejikọta ya na ọkpụkpụ capitulum.
- Dabere na mpaghara anatomical nke radial isi mgbaji, mgbaji dị n'ime "mpaghara nchekwa" nke isi radial nwere nnukwu ihe ize ndụ nke ijikọta ya na ọkpụkpụ capitulum.
▲ nhazi ọkwa Mason nke mgbaji isi radial.
▲ Ihe gbasara nsusu ọnụ onye ọrịa gbajiri agbaji, ebe a na-edozi isi radial na efere ígwè na kposara, na-edozi capitulum nke humerus site na iji kposara Bold.
