Enthesitis assessment - Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) The Maastricht ankylosing spondylitis enthesitis score (MASES), developed in patients with AS, has been used in AS and AxSpA consistently, with good performance. • MASES is a validated score mainly used in research. • Thirteen sites are assessed: - Costochondral 1 right/left (a) - Costochondral 7 right/left (b) - Spina iliaca anterior superior right/left (c) - Crista iliaca right/left (d) - Spina iliaca posterior right/left (e) - Processus spinosus L5 (f) - Achilles tendon, insertion right/left (g) • All sites are scored as 0 or 1 • The MASES is the sum of all site scores (from 0 to 13) ref: Heuft-Dorenbosch L, Spoorenberg A, van Tubergen A et al.
