46% yo kuvunika amaguru aherekejwe no kuvunika kwa malleolar inyuma. Uburyo bwa posterolateral uburyo bwo kubona neza no gutunganya malleolus yinyuma nubuhanga bukoreshwa muburyo bwo kubaga, butanga ibyiza bya biomehanike ugereranije no gufunga no gufunga anteroposterior screw. Nyamara, kubice binini byavunitse bya malleolar cyangwa kuvunika kwa malleolar inyuma birimo colliculus yinyuma ya malleolus yo hagati, uburyo bwa posteromedial butanga uburyo bwiza bwo kubaga.
Kugereranya urwego rugaragara rwa malleolus yinyuma, impagarara kumitsi ya neurovasculaire, hamwe nintera iri hagati yigitereko nu mitsi itwara imitsi muburyo butatu butandukanye, abashakashatsi bakoze ubushakashatsi bwa cadaveric. Ibisubizo biherutse gusohoka mu kinyamakuru FAS. Ibyagaragaye mu ncamake ku buryo bukurikira:
Kugeza ubu, hari uburyo butatu bwingenzi bwa posteromedial yo kwerekana malleolus yinyuma:

Ku bijyanye n’impagarara zifata imitsi y’imitsi, uburyo bwa PM bufite impagarara nke kuri 6.18N ugereranije n’uburyo bwa mePM na moPM, byerekana ko bishoboka ko umuntu ashobora gukomeretsa gukurura imitsi mu mitsi.
Kubireba intera igaragara ya malleolus yinyuma, inzira ya PM nayo itanga imenyekanisha ryinshi, ryemerera 71% kugaragara kwa malleolus. Mugereranije, uburyo bwa mePM na moPM butuma 48.5% na 57% byerekana malleolus yinyuma.
Igishushanyo cyerekana intera igaragara ya malleolus yinyuma kuburyo butatu. AB yerekana urwego rusange rwa malleolus yinyuma, CD igereranya urwego rwerekanwe, naho CD / AB ni igipimo cyo kwerekana. Kuva hejuru kugeza hasi, ibyerekanwe kuri mePM, moPM, na PM birerekanwa. Biragaragara ko inzira ya PM ifite intera nini yo kwerekana.
Kubireba intera iri hagati yo gutemwa nu mitsi iva mu mitsi, inzira ya PM nayo ifite intera nini, ipima 25.5mm. Ibi biruta mePM ya 17.25mm na moPM ya 7.5mm. Ibi byerekana ko uburyo bwa PM bufite amahirwe make yo gukomeretsa imitsi ya neurovasculaire mugihe cyo kubagwa.
Igicapo cerekana intera iri hagati yo gutemagurwa hamwe nu muyoboro w'amaraso uva kuri ubwo buryo butatu. Uhereye ibumoso ugana iburyo, intera ya mePM, moPM, na PM irerekanwa. Biragaragara ko inzira ya PM ifite intera nini na bundle yimitsi.
