This pattern is part of a long series I'm doing to build up to a life-sized skeleton. It doesn't detail the creation of any bones, but contains patterns for the ligaments involved in the attachment to the skull to the spine, and description of how to attach them to the existing bones you have created. I also contains details of the final spinal ligaments, including one that runs all the way from the skull down to the coccyx.
Difficulty:
Easy - medium
You will need:
- A 1mm crochet hook
- #10 crochet cotton in grey
- A darning needle
- A crocheted skull
- A crocheted vertebral column (this links to the first of the vertebrae, links to the rest can be found on my summary pattern page)
It is also useful to have attached the sacrum to the base of the spine.
In the creation of the skeleton I have so far assembled the ribcage and added the arms, but this is not necessary before completing this step.
Position the body face-downwards (so that the scapula are facing you), and do the same with the head, placing it just above the neck.
For the apical ligament of the dens:
ch5
Row 1: sc in the 2nd chain st from hook, then sc in each of the next 3 chain sts. ch1, turn (4sc)
Sew one end of this to the end of the dens of the axis bone, and the other end to the back of the hole in the base of the skull (i.e. to the side closest to the front of the skull)
For the alar ligaments (make 2):
ch8
ch8
Row 1: sc in the 2nd chain st from hook, then sc in each of the next 6 chain sts. ch1, turn (7sc)
Row 2: sc4, hdc3. ch1, turn
Row 3: make 2hdc in the first st, hdc2, sc, slip3 (8sts)
Fasten off
Sew the thinner end of these to the side of the hole in the skull and the thicker ends to the sides of the dens. The cast-off edge should be furthest away from the tip of the dens, as shown in the photos.

For the cruciate ligament:
ch8
ch8
Row 1: sc in the 2nd chain st from hook, then sc in each of the next 6 chain sts. ch1, turn (7sc)
Row 2: sc4, ch8, sc in the 2nd chain st from hook, then sc in the next 6 chain sts. sc in the first st you crocheted into before you made the ch8, then sc in the next 2sts. Make 2sc in the last st.
Sc in the back loop of the first of the 8 chain sts you made originally (see image 1). sc in the back of the next 3 of these chain sts (image 2), then ch5. Sc in the 2nd chain st from hook and in the next 4 chain sts (image 3). Sc in the back of the same chain st you crocheted into before making the ch5, then sc in the back of each of the following 3 chain sts.
Fasten off

This ligament should be sewn so that the ends of the central (thicker) stripe are attached to the sides of the atlas, as shown in the photo. The shorter chain perpendicular to this strip should be sewn to the body of the axis, and the longer one should be sewn to the hole in the base of the skull, around the same place as where you attached the apical ligament.
For the posterior longitudinal ligament:
ch209

Row 7: sshhss, slip9, sshhss, slip9, sshhss, slip9, sshhss, slip8, sshhss, slip1
Fasten off
Sew this to the inside of the spinal column. Each widened section should sit in between each subsequent vertebra, and the top edge (the other end to where the cast-on end is) should be sewn to the back of the hole in the base of the head, above the cruciate ligament.
For the joint capsules of the atlantooccipital joint (make 2):

ch4
Round 1: sc in the 2nd st from hook and the next chain st. Make 3sc in the last chain st, then sc in the back of the previous chain st. Make 2sc in the back of the first chain st you crocheted into. (8sc)
Round 2: make 2sc in the first st, sc, make 2sc in each of the next 3sts, sc, make 2sc in each of the last 2sts (14sc)

Sew this to the back of the neck. The thicker edge should be sewn to the top of the atlas bone, and the thinner edges should be sewn to the remaining edge of the hole at the base of the skull that you haven't yet sewn any ligaments to (i.e. the edge closest to the back of the head)

Sew this section to the back of the skine and skull as shown below. Each of the sections that stick out should be sewn between the spinal processes of adjacent vertebrae, with the top one being sewn between the atlas and the base of the skull.
