ESP Ltd manufactures and sells complete human skeletons (with or without ligaments and/or muscle attachments), disarticulated human skeletons and any individual bone in the human body. A number of skull variants are available as options. All are available in either standard or medical quality. ESP Ltd uses a unique bone-like material which closely resembles natural bone in looks, weight, texture and durability. Many joints can be supplied as well as bones showing osteoporosis and arthritis. Vertebrae models are available in many variants and our unique Lifting Manikin demonstrates correct lifting technique as well as the effects on the spine of incorrect lifting technique. The Lifting Manikin is our own design and is in great demand for applications such as Manual Handling tuition.
