Achilles Heal

Perhaps if this research had come just a few millennia earlier, Achilles’ heel wouldn’t have been such a vulnerability. Researchers working to improve recovery for people with tendon and ligament injuries are increasingly interested in synthetic hydrogels – injectable material that can encourage regrowth. There have also been recent strides in techniques that use microparticles to deliver dissolvable factors to the right spot. Now a study has combined these approaches to create a hydrogel system with fibres (pink) and microgels (green) carrying dissolvable factors. Starter cells for regrowth (blue/yellow) were recruited along the fibres, their development helped by both the physical landscape and the delivery of soluble cues in a lab model (pictured) and in ruptured mouse Achilles tendons. If the injection of a hydrogel including fibres and microparticles can boost the body’s ability to repair, recovery time after all too common tendon and ligament injuries could be greatly reduced.

Major Ligaments of the Knee Joint

Anterior view of the knee joint, showing some of the major ligaments. The patella ligament is situated on the anterior aspect of the knee joint, and is not visible is this diagram.

Patellar ligament – a continuation of the quadriceps femoris tendon distal to the patella. It attaches to the tibial tuberosity.

Collateral ligaments – two strap-like ligaments. They act to stabilize the hinge motion of the knee, preventing excessive medial or lateral movement

Tibial (medial) collateral ligament –  A wide and flat ligament, found on the medial side of the joint. Proximally, it attaches to the medial epicondyle of the femur, distally it attaches to the medial condyle of the tibia.

Fibular (lateral) collateral ligament –  Thinner and rounder than the tibial collateral, this attaches proximally to the lateral epicondyle of the femur, distally it attaches to a depression on the lateral surface of the fibular head.

Cruciate Ligaments – These two ligaments connect the femur and the tibia. In doing so, they cross each other, hence the term ‘cruciate’ (Latin for like a cross)

Anterior cruciate ligament – attaches at the anterior intercondylar region of the tibia where it blends with the medial meniscus. It ascends posteriorly to attach to the femur in the intercondylar fossa. It prevents anterior dislocation of the tibia onto the femur.

Posterior cruciate ligament – attaches at the posterior intercondylar region of the tibia, and ascends anteriorly to attach to the anteromedial femoral condyle. It prevents posterior dislocation of the tibia onto the femur.

Harry&Hermione - 'Ligament' please

It’s not a thing. She’s sure of it. It’s just when she sees the full reach of him—the extension from the tops of his fingers to the leg he’s thrown out for balance—she goes to the library and finds three books on anatomy and one on geometry. It can’t be just because it’s him, surely. There’s got to be some inherent magic in the shape or line of that extension, in the way she heard something pop in the silence (ankle or hip, she isn’t sure), in the perfect balance of it. If it was just him she could admit it and move on, surely. She’s had a crush on him on and off for so long that it doesn’t even feel strange anymore.

But that’s not it.

Because her breath doesn’t catch over simple crushes any more and she’s had the image of him, fingers fully extended, leg stretched behind his body, and his head bowed almost in reverence in her head for days.

She finds nothing in the books except scientific terms and so discards them all. Maybe she’ll find it in her arithmetic book—something about certain kinds of magic found in the angles of the body, something about how the body can hold itself so taught, something about balance.

Posting a couple of my concept works from Patreon about the internal workings of orekroarks here.  

A generalized final and preliminary sketches exploring how the changes in the orekroark flight and torso anatomy work and look.  this gives a bit of an idea the kind of movement I'm looking for within this skeleton, and and extension on the direct structure of some bones.

These sketches are some of the concept and reconstruction of orekroark flight anatomy.  As an alien creature that walks both bipedally, and quadrupedally... and has the capability of flight, it has been a bit of a struggle to develope a system that allows it to retain maximum flexibility and the ability to fly.

The skeleton has been redeveloped from a very bone heavy structure to a skeleton that has a shortened ribcage with a sternal spoon, and enlargened 3 pronged processes on vertebra that accomodates both the front limbs and the wings in different connective space.  I'm still shifting around the shape and sizes of the scapulas, and other parts of the spine and pelvis.

One thing that I tried to add to this design was a lateral semi-rigid, pliable connective ligament net that anchored to the wing's scapula, pseudo ribs and the pelvis, with a ridge along the entire ligament that acts as an alternate space for flight muscles to connect to all the way towards the pelvis.  The idea was to maximize the flexibility of the creature (To that similar of a cat) while this net and the muscles connected to it were relaxed without the muscles getting too much in the way of the movements like they would if they were connected to a larger rib system with a stiff sternum.  During flight, the net would tighten, which would keep the body stiff and stable for flight, and allow the msucles connected to it to use it like a bone.

Not all of the flight muscles are connected to this ligament net.  I've still maintaned some of the connections to the main sternum and the 'flight spoon', which the scapula is also anchored to.

They always need work, but at least they are always advancing.
