   • 2004, Erbil Ünsal, Chapter II: Andersson Lesion in Early Juvenile Spondyloarthropathies, Frank Columbus (editor), Focus On Arthritis Research, page 26,

     Like arthritis, peripheral enthesitis occurs predominantly in the lower extremities, particularly in the foot, at single sites at onset, and then at several entheses throughout the course of the disease.

   • 2007, Philip Helliwell, James Woodburn, The Foot And Ankle in Rheumatoid Arthritis: A Comprehensive Guide, page 64,

     Functional entheses occur where tendinous and ligamentous structures, while not actually attaching to bone, are adjacent and in a close relationship to the underlying bone.

   • 2010, Richard J. Wakefield, Maria Antonietta D′Agostino, Essential Applications of Musculoskeletal Ultrasound in Rheumatology, page 211,

     Inflammation of the enthesis, when associated with arthritis in children, is called the syndrome of seronegative enthesopathy associated with arthritis (SEA). The entheses most commonly involved in children are the plantar aponeurosis, calcaneal enthesis, and distal and proximal patellar ligament insertions.
