Vascularised fibula or induced membrane to treat congenital pseudarthrosis of the Tibia: A multicentre study of 18 patients with a mean 9.5-year follow-up.

Background: The objective of this study was to compare outcomes of two surgical techniques used to treat congenital pseudarthrosis of the tibia (CPT), the induced membrane technique (IM) and the transfer of the contralateral vascularised fibula (VF).

Hypothesis: The IM technique produces similar outcomes to those of VF grafting in terms of healing and function, while being simpler and having a lower complication rate.

Material And Method: This retrospective multicentre study included 18 patients with a mean age of 2.

Prognostic risk factors for the development of scoliosis after chest wall resection for malignant tumors in children.

Background: Surgical resection of a malignant tumor of the chest wall in children may result in the development of progressive scoliosis. The aim of this study was to identify the risk factors associated with scoliosis following resection of a tumor of the chest wall and to evaluate the prevalence and characteristics of the scoliosis.

Methods: Forty children who underwent resection of a malignant tumor of the chest wall from 1984 to 2005 were included in a multicenter, retrospective cohort study.

Comparative study: Ponseti method versus French physiotherapy for initial treatment of idiopathic clubfoot deformity.

Background: Nonoperative treatment avoids the complications after extensive surgery for idiopathic clubfeet. The purpose of this study was to compare retrospectively French physiotherapy and Ponseti method used to treat idiopathic clubfoot in 2 institutions.

Methods: Two hundred nineteen idiopathic clubfeet (146 patients) managed during a 3-year period (2000 to 2003) were included in this study: 116 clubfeet in group FM were treated according to modified French physiotherapy (with percutaneous heel-cord tenotomy in 17%) and 103 clubfeet in group PM were treated according to the Ponseti method.

Rh-BMP-2 in distraction osteogenesis: dose effect and premature consolidation.

We asked whether locally applied recombinant-bone morphogenic protein-2 (rh-BMP-2) with a type I collagen carrier could enhance the consolidation phase in distraction osteogenesis and whether a dose effect could be reported. We performed unilateral transverse osteotomy of the tibia in 15 immature male rabbits. In Group I (five rabbits), 750 microg of rh-BMP-2 on the type I collagen sponge (Inductos, Medtronic) was locally applied on the day of osteotomy; the Group II animals (five rabbits) received 375 microg of the drug and the Group III (control group, five rabbits) had no local application.

Chondroblastoma of bone in a pediatric population.

Background: Chondroblastoma is a rare benign bone lesion that occurs in young patients and has a high rate of recurrence. The purpose of the present study was to report on eighty-seven cases of chondroblastoma in children and to identify the possible factors that increase the risk of recurrence.

Methods: We retrospectively reviewed eighty-seven cases of chondroblastoma in patients with open physes at the time of diagnosis and treatment.
