Life-size skeleton arm




This is part of a series of patterns that fit together to form a life-size anatomical skeleton. This particular pattern give the pattern for the long bones of the arm, and the ligaments of the elbow and wrist. I have previously published a pattern for the hand skeleton.

Difficulty:
Medium - difficult

You will need:
  • A crocheted hand
  • A 2.5mm crochet hook
  • A 2mm crochet hook
  • A 1mm crochet hook
  • anchor creative fino 4ply in white
  • light grey rico #10 crochet cotton
  • a pack of barbecue skewers (you will need about 18 in total) or some lengths of bamboo (and a saw to cut them to the correct length)
  • Polyester toy stuffing
  • A darning needle
  • A pair of scissors

Stuff the shaft of the bone around the barbeque skewers. Try to make this bone as smooth as possible (this may require moving the stuffing around a little to get it into a good position with regards to the skewers) . If you are using bamboo this should be cut to approximately 26cm long.

Trim the skewers so that the ends are level with the end of the bone.

Part B: the ligaments
For the right arm
Section 1: The wrist ligaments

Place the right hand face up next to the ends of the radius and ulna, as shown below. You will be attaching the radius first, so make sure that this is positioned correctly, with the pointed part of the end nearest to the thumb.

Fasten off
Sew one edge of this to the radius just to the right of where the short radiolunate is attached. The other end should be attached to the scapholunate ligament.


You should now position the ulna next to the radius. It should be positioned so that the head curves towards the radius, as shown below.

For the ulnolunate ligament:
ch3
Row 1: sc in the 2nd chain st from hook and the next st. ch1, turn (2sc)
Row 2: sc in each st. ch1, turn
Row 3: sc in each st
Fasten off
(Note: The ends of this ligament that you sew to the bones are perpendicular to the grain of the rows)

Sew one end of this ligament to the top right-hand side of the ulna, and the other to the lower left-hand edge of the lunate.

ch7
Row 1: sc in the 2nd st from hook and the next 5sts (6sc)
Fasten off
Sew one end of this to the left-hand side of the radius, and the other to the centre of the ulna.

You now need to turn the hand and arm over so you can add the dorsal ligaments

For the dorsal radiocarpal ligament:
ch7
Row 1: sc in the 2nd chain st from hook and the next 5sts. ch1, turn (6sc)
Rows 2 - 3: (2 rows) sc in each st. ch1, turn
Row 4: hdc3, sc, slip1
Fasten off
Sew the thicker end of this to the right-hand edge of the radius, and the other end to the lower left-hand edge of the triquetrum.


For the distal radioulna ligament:
ch6
Row 1: sc in the 2nd chain st from hook and the next 4sts. ch1, turn (5sc)
Row 2: sc in each st. ch1, turn
Row 3: hdc2, sc, slip2. turn
Row 4: slip2, sc, hdc2
Fasten off
Sew the thicker edge of this to the right-hand side of the radius, and the other end to the right-hand edge of the ulna (so that it overlaps most of the bone)




Section 2: The elbow ligaments

Place the humerus next to the heads of the radius and ulna. The hooked part of the ulna should be in contact with the dip you created in the end of the humerus (see images below)

Side view of humerus positioning



For the ulna collateral ligament (part 1):
This consists of 2 parts which form a sort of v-shape between the humerus and the ulna

For the ulna collateral ligament (part 2):
ch7
Row 1: sc in the 2nd chain st from hook and the next 5 chain sts. ch1, turn (6sc)
Row 2: sc in each st. ch1, turn
Fasten off
Sew one end to the coronoid process of the ulna and the other end to the humerus, just below where you attached the previous ligament.




Turn the arm over (we are going to add ligaments to the other side of the joint)

For the lateral ulna collateral ligament:
ch9
Row 1: sc in the 2nd chain st from the hook and the next 7sts. ch1, turn (8sts)
Row 2: sc in each st

Row 2: sc in each st
Row 3: hdc4, sc2, slip2. ch1, turn
Fasten off

Sew the thicker end of this ligament to the coronoid process of the ulna, just underneath where you attached the lateral ulna collateral ligament. Wrap the ligament around the head of the ulna, then sew the other end to the opposite side of the coronoid process of the ulna (as shown in the 3rd image)



For the joint capsule ligaments:
The joint capsule has been made in several parts

ch13

Sew the jagged edge of this ligament inside the curve of the head of the ulna (along the edge of the trochlear notch). The corner of the ligament should extend under the ulna collateral ligament and attach to the radius. Sew the other end to the humerus, just above and left of where the lateral ulna collateral ligament attaches. The green lines in the third image show where you should sew the ligament to the bone.





Flip the arm over (again), so the other side of the elbow is facing upwards
ch5

Sew the curved edge inside the curve of the head of the ulna. Tuck the ends behind the ligaments that are already there, then sew the other end to the humerus, around where the other 2 ligaments are attached. Once again the green lines in the 2nd image show where the ligament should be attached.


ch21
Row 1: sc in the 2nd chain st from hook and the next 19 sts. ch1, turn (20sc)
Rows 2 - 3: (2 rows) sc in each st. ch1, turn

Sew the cast-on edge of this to the humerus (to the section that doesn't have any ligaments attached yet). This can be seen in images 1 and 2, which show it from different angles.
Sew the cast-off edge of this ligament to the head of the radius, just above where the anula ligament sits. The corner of the ligament should also be sewn to the ulna, around the side of the coronoid process.

For the transverse ligament:
This is the last ligament of the elbow joint. It attaches between 2 parts of the head of the ulna.
ch9
Row 1: sc in the 2nd chain st from hook and the next 7sts
Fasten off
Sew across the curve of the ulna head on the side of the bone where the 2 parts of the ulna collateral ligament are situated.




The final part of this pattern involves creating the interossus membrane between the ulna and radius. 

With a 1mm crochet hook and grey #10 crochet cotton ch5
Row 1: sc in the 2nd chain st from hook and the next 3 chain sts. ch1 turn (4sc)
Row 2: make 2sc in the first st, sc, sc2tog. ch1, turn
Row 3: sc2tog, sc, make 2sc in the next st. ch1, turn
Repeat these last 2 rows 24 times more

Row 52: make 2sc in the first st, sc, sc2tog. ch1, turn
Row 53: sc2tog, sc, make 2sc in the next st
Fasten off

Sew this between the ulna and radius. You should leave a small gap (about 2.5cm) at the top and bottom between the end of the ligament and where the 2 bones touch.

ch5
Row 1: sc in the 2nd chain st from hook and the next 3 chain sts. ch1 turn (4sc)
Row 2: make 2sc in the first st, sc, sc2tog. ch1, turn
Row 3: sc2tog, sc, make 2sc in the next st. ch1, turn
Row 4: make 2sc in the first st, sc, sc2tog. ch1, turn
Row 5: sc2tog, sc, make 2sc in the next st. ch1, turn
Row 4: make 2sc in the first st, sc, sc2tog
Fasten off

Sew this between the ulna and radius around where they touch at the wrist end of the arm.  There should be a small triangular section where there is no ligament present between the 2 sections of interossus membrane.


For the oblique cord:
ch13
Row 1: sc in the 2nd chain st from hook and the next 11 chain sts. ch1, turn
Row 2: sc in each st
Fasten off

Sew this to between the ulna and radius on the elbow edge of the bones. It should be sewn next to the interossus membrane on the radius side, and the other end should be sewn to the head of the ulna, to teh underside of the coronoid process.

For the left arm
The left arm is assembles in exactly the same way as the right, just mirrored. I have included a photo tutorial for this, but the crochet is exactly the same.

Radioscaphocapitate

Long radiolunate

short radiolunate/ radioscapholunate

Ulnolunate

Ulnotriquetral

Ulnocapitate

volar radioulna

Turn hand over

dorsal radiocarpal

distal radioulna

Elbow ligaments
ulna collateral ligament (part 1)

ulna collateral ligament part 2
(ignore the anular ligmaent of the radius for the minute)

Turn arm over
lateral ulna collateral ligament


radial collateral ligament

anular ligament of the radius


Joint capsule parts 1 and 2

joint capsule part 3

Joint capsule part 4





You then need to attach the transverse ligament and the interossus membrane in exactly the same way as before.


That's all! I hope you have enjoyed this pattern - if you have please think about following my Instagram, where you can keep up to data with all the patterns I release, as well as whatever project I'm currently working on. I'm currently working through releasing the various parts of the pattern of the rest of the skeleton.
