Akụkọ - Atụmatụ ahụike nke "ọnyá ọnụ" nke nkwonkwo ikpere aka

Mgbaji isi radial na olu radial bụ mgbawa nkwonkwo ikpere aka a na-ahụkarị, nke na-esikarị n'ike axial ma ọ bụ nrụgide valgus apụta. Mgbe nkwonkwo ikpere aka dị n'ọnọdụ gbatịpụrụ agbachapụ, a na-ebufe 60% nke ike axial dị n'aka ekpe gaa n'isi radial. Mgbe mmerụ ahụ merụrụ isi radial ma ọ bụ olu radial n'ihi ike, ike ịkpụcha akpụkpọ ahụ nwere ike imetụta capitulum nke humerus, nke nwere ike ibute mmerụ ahụ ọkpụkpụ na cartilage.

Na 2016, Claessen chọpụtara ụdị mmerụ ahụ kpọmkwem ebe mgbawa isi/olu radial na mmebi ọkpụkpụ/cartilage na capitulum nke humerus. A kpọrọ ọnọdụ a "ọnya ọnụ," yana mgbawa nke gụnyere njikọta a nke a na-akpọ "nchịkọta ọnụ ọnụ." N'akụkọ ha, ha tinyere ikpe iri nke mgbawa ọnụ ọnụ ma chọpụta na ikpe 9 nwere mgbawa isi radial nke a na-akpọ Mason ụdị II. Nke a na-egosi na site na mgbawa isi radial nke Mason ụdị II, ekwesịrị inwe nghọta ka mma maka mgbawa isi nke humerus nwere ike iso ya.

N'ọrụ ahụike, a na-ahụkarị mgbawa nke isusu ọnụ n'ụzọ na-ezighi ezi, ọkachasị n'ọnọdụ ebe mgbawa isi/olu radial dị ukwuu. Nke a nwere ike ibute ileghara mmerụ ahụ metụtara ya na capitulum nke humerus anya. Iji nyochaa njirimara ahụike na ihe gbasara mgbawa nke isusu ọnụ, ndị nchọpụta si mba ọzọ mere nyocha ọnụọgụgụ na nha sample buru ibu na 2022. Nsonaazụ ya bụ ndị a:

Nnyocha ahụ gụnyere ngụkọta nke ndị ọrịa 101 nwere mgbawa isi/olu radial bụ ndị a gwọrọ n'etiti 2017 na 2020. Dabere na ma ha nwere mgbawa metụtara capitulum nke humerus n'otu akụkụ ahụ, e kewara ndị ọrịa ahụ n'ime otu abụọ: otu capitulum (Otu nke Mbụ) na otu na-abụghị capitulum (Otu nke Abụọ).

Ọzọkwa, a tụlere mgbawa isi radial dabere na ebe anatomical ha dị, nke e kewara n'ime mpaghara atọ. Nke mbụ bụ mpaghara nchekwa, nke abụọ bụ mpaghara medial anterior, na nke atọ bụ mpaghara medial posterior.

Nsonaazụ nnyocha ahụ gosiri ihe ndị a chọpụtara:

Ka nhazi Mason nke mgbawa isi radial dị elu, otú ahụ ka ohere nke ịgbaji isi capitulum na-abawanye. Ohere nke mgbawa isi radial nke ụdị Mason nke mbụ na mgbawa capitulum bụ 9.5% (6/63); maka ụdị Mason nke abụọ, ọ bụ 25% (6/24); na maka ụdị Mason nke atọ, ọ bụ 41.7% (5/12).

Mgbe ọkpụkpụ isi radial gbawara agbawa ruo n'olu radial, ihe ize ndụ nke ọkpụkpụ isi capitulum belatara. Akwụkwọ ndị e bipụtara egosighi ihe ọ bụla gbasara ọkpụkpụ olu radial nke nwere ọkpụkpụ capitulum.

Dabere na mpaghara anatomical nke mgbawa isi radial, mgbawa dị n'ime "ebe nchekwa" nke isi radial nwere nnukwu ihe ize ndụ nke njikọta na mgbawa capitulum.
