Juvenile spondylarthropathy accounts for about 20% of all cases of chronic juvenile idiopathic arthritis. The spondyloarthropathy concept includes chronic inflammatory rheumatic conditions involving the spine, peripheral joints, and tendon insertions. There is an HLA B27 linkage and the condition predominates in boys, mean age 11 years.The usual clinical signs are asymmetrical involvement of the joints of the lower limbs associated in 30 to 50% of the cases with enthesiopathy. The diagnosis is based on the B Amor criteria and ESSG. The clinical course follows an episodic pattern in 80% of the cases.Nonsteroidal antiinflammatory drugs and local care are used. Sulfasalazine can be useful but its efficacy has not been proven. The functional prognosis is relatively good; spinal ankylosis is uncommon and hip involvement (destructive coxitis) occur in 30% of patients. About 80% of the patients have minor or no disability after a 10-year course.
