Anatomical hand skeleton

These hands are the second installment of the anatomically correct skeleton pattern that I am slowly uploading. The first is the skull, which can be found here.

Both the hands and the skull are approximately 1/5 size scale.






Difficulty:


Medium - difficult 
The stitches themselves aren't too complicated but the bones are very fiddly as they are so small.

You will need:



  • White regular sewing cotton
  • A 0.6mm crochet hook
  • A regular sewing needle
  • Toy stuffing
  • cocktail stick
Note:

  • "sc12" means "sc in each of the next 12 sts"
  • Whilst you are making each bone, try to stuff it as you go along, using the cocktail stick to push the stuffing into your crochet. Try to stuff each of the bones firmly so that they hold their shape.
  • For each of the hand bones you make try to shape them after you have made them to try and make them resemble the diagrams given.

Image showing all of the phalanges in their relative places
Part C: making them up

Lay out all of the finger bones in their relative positions, as shown below







For the fingers:
Lay out each of the fingers as shown below.

For the bones of each finger, secure thread to the bases end of the metacarpal, and thread it up through the middle of this bone and each subsequent bone. Pull tight to bring the bones together, and then secure. You may wish to also thread the yarn back the other way and secure at the opposite end to ensure the bones are held together tightly, but not too tightly that they are no longer movable.


For the wrist bones:
The wrist bones are built up one by one. I started with the right hand and then did the left hand after, with each bone being in the opposite orientation to its location in the right hand. Try not to sew the bones too tightly together as often you will need to nestle other bones in between existing ones.
Sorry about the blurriness of the images, it was difficult to take clear photos with the bones being so small.

1. First place the scaphoid and lunate in the following position, with the lunate on the left and the scaphoid in front on the right. Sew them together in this orientation.

 



 2. Next place the triquetral behind the lunate slightly above so that the top of it sticks out a little above the lunate. It should be placed so that the pointy end of the triquetral is pointing downwards, as shown below. When it is in the orrect position sew it in place



The triquetral is circled in this photo

 3. The pisiform is attached next. This lies to the left of the triquetral and lunate nestling slightly into any gap between them with the thinner end pointing outwards. Sew this in place.



The pisiform is circled


View from above. The pisiform is the left-most bone 

 4. Next, add the capitate. This sits just behind the scaphoid next to the lunate but not right next to it (You need to leave a little gap to add a bit of another bone later). The rounded end should be facing down so that the little mini spikes on the opposite end point upwards. Sew this in place.

The capitate is circled
5. The hamate is the next to be added. This is added in between the scaphoid, lunate, and capitate, with the non-pointed side nestling in the gap you left when you added the capitate, so that the other side sticks out behind the lunate, triquetral, and pisiform. Sew it in place



The wrist bones so far should look something like this

 6. After this you need to add the trapezoid. This is added to the back of the scaphoid so that the rounded bit on the other corner tucks behind the hamate. Sew it in place.




Trapezoid is circled
 7. Finally, add the trapezium. This is sewn onto the end of the scaphoid with the pointy end on the inner edge (next to the trapezoid)



The trapezium is circled

As explained above, the left hand is the same as the right hand but opposite. I have included images of the creation of the left hand, and the explanation of what is going on is the same as for the right hand.







I have placed the pisiform in slightly the wrong place in this photo - it should be in front of the triquetral not behind (the same as on the right hand), sorry!



 




To finish off:
Finally, you need to sew the finger bones to those if the wrist. The thumb bone is sewn to the trapezium, the index finger is sewn to the trapezoid, the middle finger is sewn to the capitate, and the bones of both the ring and pinkie finger are sewn to the hamate.
Back view

You may also want to sew a line of stitching through the top of the metacarpals to hold them together and make the hand look more natural.
