We report here three fully documented cases of periosteal chondroma diagnosed and treated in our hospital. There have been few references since Lichtenstein first described this condition as a separate tumour, and none of them concerned children under 10 years old. deSantos accurately describes the radiological features of the tumour. All of our patients were under 10 years old at the moment of the appearance of the lesion, which was always detected in the long bones of the upper limbs. The study included a previous histological examination in two cases and a follow-up in all of them. From this study we learned that invasive diagnosis procedures are unnecessary as we could follow the behaviour and evolution of this cartilaginous benign tumour for a long period of time.
We present a review of six cases of children with congenital pseudarthrosis of the clavicle, treated and followed up at the "La Fe" Hospital for Children. One of them had bilateral involvement. Five of them, including the bilateral case, were surgically treated at ages ranging from 18 months to 4 years. Bone graft and internal fixation with a Kirschner wire were used. Healing of the pseudarthrosis was obtained in all patients in 6-8 weeks. We discuss the suitability of early surgical treatment that, in our opinion, produces very satisfactory results.
Relative overgrowth of the greater trochanter is a problem related to proximal femoral growth cartilage damage. Eleven hips in 10 patients aged 4-13 years with acquired coxa vara were retrospectively reviewed. Distal and lateral transfer of the greater trochanter was performed in all patients. The average follow-up was 42.7 months. The causes of the overgrowth were Perthes disease, avascular necrosis after treatment of developmental dysplasia of the hip, septic arthritis and rheumatoid arthritis. Radiological assessment revealed an improvement of both the articulotrochanteric distance and the greater trochanter relative overgrowth. Values referred to the acetabulum or the neck-shaft angle remained unmodified. Clinical improvement was achieved. A fracture of the transferred greater trochanter was observed. We believe that this procedure is a simple technique, with good results and few complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
