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.

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

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

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)

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

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.

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.

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.
