    Abstract:
    INTRODUCTION: Radionuclide synovectomy/synoviorthesis (RS) to manage proliferative synovitis in persons with bleeding disorders has been utilized for decades; however, aggregate US results are limited. AIM: To determine the prevalence of RS utilization, patient and procedure related demographics and functional outcomes in United States haemophilia treatment centres (HTCs). The ATHNdataset includes US patients with bleeding disorders who have authorized the sharing of their demographic and clinical information for research. METHODS: We performed a multi-institutional, observational cohort study utilizing this dataset through 2010. Cases treated with RS procedure were compared to controls within the dataset. Standard template for data collection included patient and procedure related demographics as well as functional outcomes including range of motion (ROM) of the affected joint. Normative age- and sex-matched control ROM was obtained from published data. RESULTS: In the ATHNdataset there were 19 539 control-patients and 196 case-patients treated with RS. Patients with severe haemophilia were more likely to have had RS compared to those with mild/moderate haemophilia, although the proportion of RS performed was similar between severe HA and HB. Inhibitory antibodies, HIV and hepatitis C infection were significantly more common in cases. There were 362 RS procedures captured with 94 cases having >1 RS procedures. CONCLUSIONS: Right-sided joint procedures were more prevalent than left-sided procedures. Overall, case-patients had worse joint ROM compared to control-patients and published normative values. Geographically, there was regional variation in RS utilization, as the Southeast region had the largest percent of case-patients.
