"Pasentị iri nke mgbawa ụkwụ na-esokwa mmerụ ahụ nke distal tibiofibular syndesmosis. Nnyocha egosila na pasentị iri ise na abụọ nke skru tibiofibular distal na-eme ka syndesmosis ghara ịdị mma. Itinye skru tibiofibular distal perpendicular na elu nkwonkwo syndesmosis dị mkpa iji zere iatrogenic malreduction. Dịka akwụkwọ ntuziaka AO si kwuo, a na-atụ aro ka itinye skru tibiofibular distal 2 cm ma ọ bụ 3.5 cm n'elu elu tibial articular distal, n'akụkụ nke 20-30 ° gaa na mbara ala kwụ ọtọ, site na fibula ruo na tibia, na nkwonkwo ụkwụ nọ n'ọnọdụ na-anọpụ iche."
Ntinye aka nke skru tibiofibular distal na-ebutekarị mgbanwe na ebe ntinye na ntụziaka, ma ugbu a, enweghị usoro kpọmkwem maka ikpebi ntụziaka ntinye nke skru ndị a. Iji dozie okwu a, ndị nchọpụta si mba ọzọ ewerela usoro ọhụrụ—usoro 'angle bisector'.
Site na iji data onyonyo sitere na nkwonkwo ụkwụ 16 nkịtị, e mepụtara ụdị 16 e biri ebi nke 3D. N'ebe dị anya nke 2 cm na 3.5 cm n'elu elu tibial articular, e tinyere waya Kirschner abụọ nke 1.6 mm nke dị n'akụkụ elu njikọ ahụ nso n'akụkụ ihu na azụ nke tibia na fibula, n'otu n'otu. E jiri ihe nrịbama tụọ akụkụ dị n'etiti waya Kirschner abụọ ahụ, e jirikwa obere ihe ndọda 2.7 mm gwuo oghere n'akụkụ ahịrị bisector n'akụkụ, wee tinye skru 3.5 mm. Mgbe etinyere skru ahụ, e jiri igwe gbubiri skru ahụ n'ogologo ya site na iji igwe gbubiri iji nyochaa mmekọrịta dị n'etiti ntụziaka skru na axis etiti nke tibia na fibula.
Nnwale ihe atụ na-egosi na e nwere ezigbo nkwekọ n'etiti etiti axis nke tibia na fibula na ahịrị bisector n'akụkụ, yana n'etiti etiti axis na ntụziaka skru.
N'ụzọ dị irè, usoro a nwere ike itinye skru ahụ nke ọma n'akụkụ etiti nke tibia na fibula.
