Ankle Joint Actions: Video #16 of Introduction to Functional Anatomy

Lower leg, getting there, getting there. Gone a long way today, we're on like mild 24 of our marathon. All right we got to talk about the ankle a little bit, because unfortunately is this word bank going to work for our ankle? No, now you guys already know enough to know that the ankle has its own set of joint actions. What type of joint is the ankle? It's commonly referred to as a hinge joint. That's a little deceptive but the ankle is also two joints not one. So you have this mortise is what it's called, it's like a mortise joint, that's another one of those construction things right, where you have like a one of these shapes and a tongue that goes into it that way. So you have the end of the tibia and the fibula, the lateral malleolus of the fibula coming down and basically blocking this part of your ankle joint into what plane? What plane can this actually move? Sagittal that's it right, but alright so that's the tibiotalar ,a talocrural joint. Then you have the subtalar joint which is your heel bone, your calcaneus on the talus. Does the fibular or the lateral malleolus of the fibula extend  that low? No, so now what plane can this move in? Frontal it'll rock this way. Alright so we have sagittal here and frontal here, subtalar beneath the talus. Tibia, fibula, talus, calcaneus those are kind of the bones that make up our ankles. So we got some sagittal joint actions, and we got some frontal actions. Well I guess I actually could kill two birds with one stone here, and just make our word bank huh. So what can my ankle do in the sagittal plane? Plantarflexion and dorsiflexion, You guys are already way on top of it. Where do those terms come from, why isn't it flexion and extension? And you guys are right dr. Falinger steals all my stuff. Alright so dorsiflexion dorsal refers to top service, like the dorsal fin on a shark. dolphin! We're hardcore in this room. we're gonna refer to dorsal fins. It's going to be jaws, not some little dolphin. Shamu is a killer whale, it has killer in the name so that's that's ok, that's it in between, does funny shows but still a possible killer. Kills trick, kills trainers, all right kind of kind of coo,l I guess kind of cool not as cool as jaws, but more cool than a dolphin. All right so dorsal fin, yes I'm recording this on video and that that whole thing is just going to look like a weird aside, about my fascinations with fish that eat other fish, or in the case of killer whales and dolphins, mammals and now I've proved I watch way too much Discovery Channel. Alright so moving on we got dorsal fins top surface, flexion refers to two bones getting closer together, in this case it's the dorsal surface of the foot getting close to the tibia. Plantar flexion what is plantar refer to? The underside. Now how we get plant our flexion not really sure other than the calcaneus does actually come close to the tibia, your ankles more of a seesaw than it is like your elbow You guys cool with that. I always think like plant myself into the ground is plantar flexion and then dorsiflexion is coming up. You guys got that, now in the frontal plane plantarflexion as a rear is an actual word, it's just not used. Plantarflexion, dorsiflexion, frontal is actually eversion and inversion and this is subtalar joint actions. So eversion is what? Yes so eversion, well actually let's start with inversion because this I have a little cue to help me memorize this. Inversion is the sole of my foot facing inward. Inversion sprains happen more often right. Why do inversion sprains happen more often than eversion sprains? Okay if this is my left foot because the fibula blocks the talus, there's less stability this way. Yeah if you hear of an e-version sprain, which eversion now is the other way, foot flattening or beyond. If it goes beyond and you get an eversion sprain what often happens? Fibula fracture, not okay, not okay. Alright so we got inversion and eversion.
