How to Wrap a Uterus

A performance piece which makes the location of the ovaries in relation to the uterus, bladder and rectum hard to forget. Designed for audience participation in a large lecture theatre situation the completed assemblage makes the peritoneal folds that wrap the organs in this part of the pelvis easy to understand.

Production Information

1. Materials

Aluminium strip, approx. 1.5m of 25mm x 2.5mm
Duct tape, grey
Velcro, sew in variety, approx. 2.5m each of hook and loop
Polystyrene balls (approx. 125mm diameter), x4
Hot glue
Paper and PVA glue for Papier-mâché
Acrylic paints
Spray on sealant
Padded bags with drawstring
Brushed cotton or Polar fleece fabric in suitable colours for sweatshirts
Felt fabric, white for embroidery
Glass organza (polyester) fabric for peritoneum, approx. 5m of 140cm wide fabric
Bias binding, approx. 10m

2. Method: Strap-on Ovaries

Bend aluminium to fit the chest of an average person. Leave a bit of spring so that it will grip, in part, without the duct tape straps. Cut away excess with hacksaw if needed to make the ends even.

Make straps out of a few layers of duct tape. We found that a couple more straps were needed than shown, to go over the shoulders. Velcro was sewn onto the straps.
Cut each of the polystyrene balls with a saw about 5/8ths across the diameter. Discard the smaller pieces and hot glue pairs of the larger pieces together to make two ovoids. Using a hacksaw or similar, make a cut into the end of these to accommodate the ends of the aluminium strip. Secure with hot glue.

Papier-mâché over the polystyrene, building up the lumpy shapes of multiple follicles. Finish with finer textured paper.

When completely dry, decorate with acrylic paints and seal the completed ovaries with a spray art-sealant.

Some padded bags will protect the ovaries from accidental knocks.

3. Method - Sweatshirts

Make up the sweatshirts, using a pattern large enough to suit most people.

Create two plackets in the back of the uterus sweatshirt to accommodate the ovarian ligaments. Sew in some Velcro tabs.

Trace a design for the embroidery onto white felt. Pin in place on the sweatshirt and embroider with black stitching. Trim away the felt from around the stitching.

4. Method - Peritoneum

Sew the two layers together just under the arm of the wearer. Optional: the wrist opening can be finished with a cuff of e.g. white cotton lycra.

On one layer only of the organza (the posterior layer) sew strips of Velcro to create the Mesovarium.
On both layers sew down smaller pieces of Velcro, which join to form the Mesometrium.
The remaining free ends of the organza can be finished by roll-hemming (anterior and posterior edges) or with bias binding (lateral edges). These parts of the model illustrate the layers of the peritoneum that cover the bladder (anterior layer) and rectum (posterior layer)

Creators: Dr Brad Hurren (initial idea and academic support, painting), Fieke Neuman (sculpting, patterns and sewing). All from Department of Anatomy, University of Otago
