Njengoba kunombhalo wokubhekisela mayelana ne-incudomalleolar joint, ngitshele umsebenzi wayo oyinhloko.
Context:I-incudomalleolar joint (ngokufanele ibizwa ngokuthi i-incudomallear joint) noma i-articulatio incudomallearis iyinhlangano encane ye-synovial ephakathi kwe-malleus (hammer) ne-incus (anvil). Umsebenzi walo mthambo ukudlulisa ukudlidliza phakathi kwamathambo endlebe ephakathi, okuqondwa njengomsindo. Ngokungafani namanye amalunga e-synovial ukunyakaza kulinganiselwe kakhulu. Wonke amathambo ahamba cishe njengeyunithi, okungenani emazingeni aphansi.  Lapho isigubhu sendlebe sishukunyiselwa ngaphakathi ngenxa yokudlidliza komsindo, okudluliselwa ngendlebe yangaphandle, sidlulisela esibambweni noma emananubrium ye-mallus exhunywe ku-drum yendlebe. Ikhanda le-maleus (caput mallei) lihamba nalo futhi lidlulisela amandla/ukuhamba emzimbeni we-incus (corpus incudis), okhona ngqo ngemuva. Khona-ke, ukudlidliza komsindo kudluliselwa ku-stapeus (ku-stirrup) ngokusebenzisa i-incudostapedial joint.
Umsebenzi wejoyinti le-incudomalleolar uwukudlulisa ukudlidliza phakathi kwamathambo endlebe ephakathi.
