Childhood idiopathic chondrolysis of the hip: MRI features

Abstract

MRI in ICH clearly demonstrates cartilage loss and enables delineation of bone and muscle abnormalities. It is helpful in the differential diagnosis of hip joint disease in children and may provide further information on the progression and aetiology of ICH.

The Pelvis and Hip: Acquired Disorders

“…12.42 ). As disease progresses, extensive edema develops in the femoral head and acetabulum, joint fl uid increases, and the gluteal musculature atrophies [ 96 ].…”

Quadril doloroso na criança

“…Remodelação óssea, edema de medula óssea, atrofia muscular e derrame articular em pequena quantidade também são demonstrados (7) . Realce sinovial ocorre apenas em alguns casos e a ausência deste pode ajudar a diferenciar de artrite idiopática juvenil e artrite séptica (Figura 7).…”

Subtotal capsulectomy for idiopathic chondrolysis of the hip: A clinical, radiological and histological study

“…38 Premature closure of the femoral capital physis 9 and protrusio acetabuli 39 is also documented. Late manifestations of the disease reflect the secondary degenerative changes of osteoarthritis.…”

“…Early features included focal cartilage loss, bone marrow oedema, a small joint effusion without significant synovial enhancement, muscle wasting and signs of bone remodelling. 38,40,41 Late features were widespread cartilage loss and bone erosions. 38 Our case series demonstrated similar features with the notable exception of early articular cartilage destruction affecting the acetabular cartilage (superomedial weightbearing areas) more than the femoral head cartilage as suggested by earlier reports.…”
