“…In our study the values for the distal femur and the FEHMW showed less increase with age than those of the control group, but the flattening of the epiphysis was as described in other skeletal dysplasias. 11 The development of the proximal tibial epiphysis followed a similar pattern, although the deformation and degeneration were less pronounced than in the distal femur. Physeal irregularity and metaphyseal intrusions were also more severe in the distal femur, which may be due to the different anatomy of these growth areas.…”

“…This is probably due to the degenerative changes. Schlesinger et al 11 have described the radiological parameters for the distal femoral epiphysis in bone dysplasias. In our study the values for the distal femur and the FEHMW showed less increase with age than those of the control group, but the flattening of the epiphysis was as described in other skeletal dysplasias.…”

“…The clinical and radiological outcome is largely based on studies with a very Fig. 1 Diagram of the radiological measurements modified from the method of Schlesinger et al 11 (FM, femoral metaphyseal width; FH, femoral epiphyseal height; FE, femoral epiphyseal width; TH, tibial epiphyseal height; TE, tibial epiphyseal width; TM, tibial metaphyseal width).…”

We examined clinically and radiologically the knees of 46 patients (27 females and 19 males) with diastrophic dysplasia. The age of the patients varied from newborn to 38 years. A total of 18 patients was followed during their growth until adolescence. The knees of two legally aborted fetuses appeared on examination to be macroscopically normal and congruous. Excessive valgus deformity of the tibiofemoral weight-bearing angle with a mean of 14° was noted in infancy. Most of the patients had marked instability of the knees. The range of movement of the knee began to decrease before the age of five years. There were signs of early degeneration and deformation of the bony epiphyses before the age of six years. The patellofemoral joint was abnormal from an early age. A marked patella infera, often associated with a lateral position of the patella with bony fragmentation, was noted. The knee in diastrophic dysplasia is basically unstable, showing early deformation of the subchondral bone and degeneration of the joint. Early degeneration of the joints is a cause of major disability in patients with severe osteochondrodysplasias.

“…In such subtle cases, it can be helpful to determine the ratio between the height of the distal femoral epiphyseal and its epiphyseal/metaphyseal width, which is decreased in MED. Values can be compared to established norms [ 108 ]. This dysplasia usually become apparent after 2 years of age, and mild cases can manifest in adulthood merely with relatively short stature.…”

The chapter begins with a section on the normal development of the pelvis, acetabulum, and femoral neck, head, and epiphysis. Discussion of congenital and developmental abnormalities follows. Proximal focal femoral defi ciency is described fi rst. This is followed by a discussion of both intrauterine hip dislocation and a lengthy discussion of developmental dysplasia of the hip (DDH). Within this section, many different imaging techniques are broken down, the treatment of DDH by osteotomies is discussed, and postoperative complications as well as differential diagnosis are explained. Sections on coxa vara and acetabular protrusion follow. Femoral head dysplasia is broken down into both localized and generalized disorders: microepiphyseal dysplasia, Meyer dysplasia, osteochondritis dissecans-like femoral head dysplasia, multiple epiphyseal dysplasia, and epiphyseal dysgenesis in hypothyroidism.

Objective. To describe radiologic features of patients with juvenile idiopathic arthritis (JIA) in a standardized manner, to test the reliability and feasibility of this description, and to correlate these features with clinical signs as a first step in the development of a standardized assessment method.Methods. The placebo-controlled study of sulfasalazine in patients with oligoarticular, extended oligoarticular, and polyarticular JIA performed by the Dutch Juvenile Idiopathic Arthritis Study Group yielded the data for this study. All trial entry radiographs (clinically involved joints and contralateral joints) were scored (in consensus by a skeletal radiologist and pediatric rheumatologist) for the presence of swelling, osteopenia, joint space narrowing, growth abnormalities, subchondral bone cysts, erosions, and malalignment.Results. Data on 67 of 69 patients were analyzed. The mean age was 9.1 years (range 2.5-17.6 years), and the median disease duration was 24 months (range 5-176 months). Thirteen percent of the patients were IgM rheumatoid factor (IgM-RF) positive, and 16% were HLA-B27 positive. All 68 clinically evaluated joints were included in the maximum of 19 radiographed joints (or joint groups) per patient. The mean number of radiographed joints per patient was 7 (range 2-15); knees, hands, ankles, and feet were most frequently affected. Fifty-eight patients (87%) had radiologic abnormalities in at least one joint (soft-tissue swelling in 63% of patients, growth disturbances in 48%, joint space narrowing in 28%, and erosions in 15%). In total, half of the radiographs of the clinically involved joints showed radiologic abnormalities, including two-thirds of the radiographs of the clinically affected hands and knees.
