Yttrium has been used as the material of choice for synoviorthesis in our centre since 1984. An audit was carried out to determine the long-term results of this modality for treating elbow joints. An unacceptably high percentage of patients lost range-of-movements in the articulation treated. Good results were achieved with respect to a reduction in the bleeding incidences. It is suggested that another isotope be utilized and that other centres carry out an audit and publish their data.
