MR imaging of the ischiopubic synchondrosis

A Case of van Neck-Odelberg Disease and Intermittent Overuse Injury

“…Ischiopubic synchondrosis was found to occur in 61% of a population. 6 Fibrous bridging and fusiform swelling of adjacent soft tissue can be observed as well like the current case. 6 Dominant swinging leg is used in skilled motor activities, whereas nondominant standing leg sustains major strain.…”

“…6 Fibrous bridging and fusiform swelling of adjacent soft tissue can be observed as well like the current case. 6 Dominant swinging leg is used in skilled motor activities, whereas nondominant standing leg sustains major strain. In a cohort of Herneth et al, lesions were left sided in 78% of children with unilateral IPS.…”

Groin and Medial Thigh Pain in a 17-year-old Girl

“…The ischiopubic synchondrosis located at the junction of the inferior pubic ramus and ischial tuberosity behaves like a primary ossification center and fuses in late childhood to early adolescence. This normal fusion process may display bony enlargement, mineralization, and lucency, which are well described [1][2][3][4][5][6][8][9][10][11][12]. Junge and Heuck [12] reported one in seven children 5 to 15 years old had ''irregular'' radiographic features of the ischiopubic synchondrosis in their series.…”

Ischio-pubic osteochondritis (Van Neck-Odelberg disease): A case report

“…In some cases, children may present with pain in the groin, hip or gluteal region with restriction of hip movement and limping gait. This combination of clinical symptoms is usually referred as Synchondrosis Ischio-pubic syndrome (SIS) [3,4]. On plain X-rays, SIS is outlined as a bulge with areas of demineralization at IPS, referred by Odelberg and van Neck as "osteochondritis ischio-pubica" or "Van Neck-Odelberg disease" [5,6].…”

“…Usually, ossification of synchondrosis is clinically asymptomatic, though in some cases, children may complain of pain in the groin, hip or gluteal region. It may be associated with limitation of hip movement and limping gait referred as synchondrosis Ischiopubic syndrome (SIS) [3,4]. Odelberg and van Neck described radiographic changes of SIS as bulge with demineralization of the ischio-pubic fusion region.…”
