Osteochondritis dissecans in association with legg-calve-perthes disease

Case reports - Free osteochondral fragment caught in the acetabular fossa in the osteochondritis dissecans after Legg-Calvé-Perthes' disease-report of 2 cases

“…Both of our cases were 12 years old when the LCPD was diagnosed. In other reports, the average age at onset of LCPD was 9.3 years (Bowen et al 1986), 8.4 years (Katz and Siffert 1979), 8 years (Öster-man and Lindholm 1980) and 10 years (Rowe et al 1989). The risk of developing this complication seems to be greater in older children.…”

“…This tendency to healing also explains the rarity of loose body formation. Katz and Siffert (1979), Österman and Lindholm (1980), and Bowen et al (1986) reported their experiences of spontaneous healing of OCD after LCPD. We (Rowe et al 1989) have also had 7 cases of OCD in a series of 363 LCPD hips, and observed radiographic healing in 4, spontaneous healing in 3 and healing after drilling and a bone graft in 1.…”

Fate of the osteochondral fragments in osteochondritis dissecans after Legg-Calvé-Perthes' disease

“…Reviewing the literature, [1][2][3][4][5][6][7] we found that 87 cases (92 hips) with OCD after LCPD had been reported in 28 articles (Table III). The current series includes seven cases which we reported in 1989 8 with further follow-up, and six new cases.…”

“…3,5,7 In our group, we followed the patients until a mean age of 24 years and observed spontaneous healing in seven hips and progression towards healing in three. From all the well-documented cases, the 66 in the literature and our 13, we were only able to find six examples of complete separation of the fragment into the joint.…”

“…Several reports described OCD as occurring in up to 4% of patients with LCPD. [5][6][7][8] The treatment of this lesion has not been defined and has varied between simple observation and surgical removal of the fragment. 5,[9][10][11][12][13] We suggest a form of treatment for this lesion, based upon our experience of 13 patients and a review of the literature.…”
