A white cardboard box with an off-white label on the lid contains two pieces: a hip prosthesis made primarily of clear Perspex and a second component made of opaque white plastic.
The prosthesis consists of a “ball” element attached to a tapered “femoral” stem. The prosthesis is a single solid piece. A metal stem is visible within the clear stem. A pattern of metal wires are visible within the clear ball element. These are x-ray markers that will indicate whether the device has rotated following installation.
The second component has a curved face opposite a textured face.
Accession Number: 2023.JAC.283
Alternative Name:
Perspex (Acrylic), White Plastic of unknown composition.
The label on the lid of the box includes the following information: “BUXTON’S MODEL// PERSPEX HIP PROSTHESIS// WITH X-RAY UMBRELLA// SHALLOW GROOVED STEM// HEAD 45mm. STEM 80mm.// GUTTER 36mm.”
Stamped on a portion of the metal reinforcement that is visible within the clear ball: “45”, “7 cm”, “DOWN-MAYER”, “PAT. PEND”.
Box: Height = 5.2. Width = 11.5, Length = 5.5.
This prosthesis appears similar in form and purpose to the Judet acrylic prosthesis. It is installed transversally through the lateral cortex of the femur. (Miller 2002, 214)
Both elements of prosthesis appears to be unused and undamaged.
