Kashi 46% na karyewar idon ƙafa mai juyawa suna tare da karyewar malleolar ta baya. Hanyar posterolateral don gani kai tsaye da kuma daidaita malleolus ta baya wata dabara ce da aka saba amfani da ita ta tiyata, tana ba da fa'idodi mafi kyau na biomechanical idan aka kwatanta da raguwar rufewa da gyara sukurori anteroposterior. Duk da haka, ga manyan gutsuttsuran karyewar malleolar ta baya ko kuma karyewar malleolar ta baya da ta shafi posterior colliculus na medial malleolus, hanyar posteromedial tana ba da kyakkyawan ra'ayi na tiyata.
Domin kwatanta yanayin fallasa na malleolus na baya, tashin hankali akan tarin jijiyoyin jini, da kuma nisan da ke tsakanin yankewa da tarin jijiyoyin jini a cikin hanyoyi uku daban-daban na posteromedial, masu bincike sun gudanar da wani bincike na gawarwaki. An buga sakamakon kwanan nan a cikin mujallar FAS. An taƙaita sakamakon kamar haka:
A halin yanzu, akwai manyan hanyoyi guda uku na posteromedial don fallasa posterior malleolus:
1. Hanyar Tsakiyar Tsakiyar Tsakiya (mePM): Wannan hanyar ta shiga tsakanin gefen baya na medial malleolus da kuma jijiyar baya ta tibialis (Hoto na 1 yana nuna jijiyar baya ta tibialis).
2. Hanyar Posteromedial da aka Gyara (moPM): Wannan hanyar ta shiga tsakanin jijiyar baya ta tibialis da kuma jijiyar longus ta lankwasa (Hoto na 1 yana nuna jijiyar baya ta tibialis, kuma Hoto na 2 yana nuna jijiyar longus ta lankwasa).
3. Tsarin Bayan Jijiyoyi (PM): Wannan hanyar tana shiga tsakanin gefen tsakiya na jijiyar Achilles da kuma jijiyar hallucis mai tsayi (Hoto na 3 yana nuna jijiyar Achilles, kuma Hoto na 4 yana nuna jijiyar hallucis mai tsayi).
Dangane da tashin hankali a kan tarin jijiyoyin jini, hanyar PM tana da ƙaramin tashin hankali a 6.18N idan aka kwatanta da hanyoyin mePM da moPM, wanda ke nuna ƙarancin yiwuwar raunin jan hankali a cikin tarin jijiyoyin jini a lokacin tiyata.
Dangane da yanayin fallasa na malleolus na baya, hanyar PM kuma tana ba da ƙarin fallasa, wanda ke ba da damar ganin malleolus na baya da kashi 71%. Idan aka kwatanta, hanyoyin mePM da moPM suna ba da damar fallasa malleolus na baya da kashi 48.5% da 57% bi da bi.
● Zane-zanen yana nuna kewayon fallasa na malleolus na baya don hanyoyi uku. AB yana wakiltar jimlar kewayon malleolus na baya, CD yana wakiltar kewayon fallasa, kuma CD/AB shine rabon fallasa. Daga sama zuwa ƙasa, an nuna kewayon fallasa na mePM, moPM, da PM. A bayyane yake cewa hanyar PM tana da mafi girman kewayon fallasa.
Dangane da nisan da ke tsakanin yankewar da kuma jijiyoyi, hanyar PM ita ma tana da mafi girman nisa, wanda ya kai 25.5mm. Wannan ya fi 17.25mm na mePM da 7.5mm na moPM girma. Wannan yana nuna cewa hanyar PM tana da mafi ƙarancin yiwuwar raunin jijiyoyi a lokacin tiyata.
● Zane-zanen yana nuna nisan da ke tsakanin yanke da kuma tarin jijiyoyin jijiyoyi na hanyoyin guda uku. Daga hagu zuwa dama, an nuna nisan hanyoyin mePM, moPM, da PM. A bayyane yake cewa hanyar PM tana da mafi girman nisa daga tarin jijiyoyin jijiyoyi.
