“…The etiologies of those disorders are not entirely understood [6][7][8]. Synovitis and joint effusion, which are suspected to play a significant role in the interruption of blood supply of the femoral head, occur in both disorders [9]. JIA with affected hip joints may result in femoral head necrosis as well [10,11].…”

Background: This study aimed to determine the clinical and radiological course in children who had Legg–Calvé–Perthes disease (LCPD) associated with juvenile idiopathic arthritis (JIA). Methods: In a retrospective chart review between 2007 and 2019, eight consecutive JIA patients diagnosed with concomitant LCPD were identified and compared with a case-control group of 10 children with LCPD only. Results: LCPD was diagnosed at a mean age of 8.1 years (3.0–14.7) in children with JIA as compared to 6.1 years (2.9–10.0) in controls. According to the modified Harris Hip Score (mHHS), four children with JIA and all controls had an excellent result. Regarding the fragmentation severity and the duration of each stage, we found no differences using the lateral pillar and modified Elizabethtown classification. Five hips were classified as Stulberg I/II, two hips as Stulberg III, and one hip as Stulberg V with no evidence of hip dysplasia or severe overcoverage in either group. Conclusions: The radiological outcome of LCPD did not differ between both groups, while the clinical outcome was slightly better in controls. Physicians should be aware that children with LCPD may have JIA too. In suspicious cases, further investigations are recommended, and patients should be referred to pediatric rheumatologists.

Bilateral hip involvement in Legg-Calvé-Perthes disease occurs in approximately 10-13% of cases. Although both synchronous and metachronous involvement of the two hips have been described, metachronous involvement is rare and generally occurs within 6 months to 4 years of initial diagnosis. We report the cases of two patients diagnosed with late metachronous involvement of the contralateral hip 8.5 and 9.8 years after initial presentation. This is later than previously reported metachronous involvement in Legg-Calvé-Perthes disease and emphasizes that patients with Legg-Calvé-Perthes disease may be at prolonged risk for recurrent disease.

Radiographic findings in Legg-Calvé-Perthes disease (LCPD) are well known. Four classic stages have been described: incipient stage, avascular stage, fragmentation stage, and residual stage. Final femoral morphology is normally coxa magna, which is associated frequently with hypertrophy of the articular cartilage. We describe five patients with a hip process that initially presented clinical and radiographic findings compatible with LCPD. However, none of these patients showed the typical sequence of the radiographic stages. Instead, the early signs were the formation of rounded areas of rarefaction in the epiphysis and/or the metaphysis with considerable surrounding osteoporosis, early narrowing of the articular space, and final coxa breva morphology with signs of osteoarthritis. No condensation or fragmentation stages were observed. The pathologic study showed complete atrophy of the synovial villi with hyaline cartilage and bone necrosis. The patients described herein presented an intraarticular hip process, initially with signs and symptoms similar to LCPD but with an ultimate clinical evolution that differs from ordinary LCPD.
