BACKGROUND: Neurofibromatosis type 1 is a hereditary disease that can lead to pseudoarthrosis of various long bones. Rarely, pseudoarthrosis affects the forearm, and to the best of our knowledge, this is the first reported case of pseudarthrosis of the distal radius treated by this unique method. METHODS: We present a case of a 7-year-old male who underwent multiple operations to treat pseudoarthrosis of the distal radius. RESULTS: After failed conservative and operative fixation augmented with autologous iliac crest bone grafting, the patient underwent a successful double-barrel vascularized free fibula graft while preserving the physis of the distal radius...

HYPOTHESIS: We aimed to report our experience in treating congenital pseudarthrosis of the clavicle (CPC). MATERIALS AND METHODS: A retrospective search of the archive of our institute was performed; 27 cases (12 male and 15 female patients) affected by CPC were recorded. Among these patients, 19 underwent surgical intervention for cosmetic appearance between 1960 and 2015. Of 19 patients, 18 were treated by pseudarthrosis resection and stabilization with a Kirschner wire, whereas in 1 case, the osteosynthesis was performed with a plate...

Patients with Neurofibromatosis type 1 display delayed fracture healing and the increased deposition of fibrous tissue at the fracture site. Severe cases can lead to non-union and even congenital pseudarthrosis. Neurofibromatosis type 1 is caused by a mutation in the NF1 gene and mice lacking the Nf1 gene show a fracture repair phenotype similar to that seen in patients. Tissue from the fracture site of patients with Neurofibromatosis type 1 and from mice deficient in the Nf1 gene both show elevated levels of β-catenin protein and activation of β-catenin mediated signaling...

There is a lack of studies reporting on rhBMP-2 application in pediatric orthopaedics, although few reports demonstrated promising results of the use of rhBMP-2 in children, especially for spine fusion and for the treatment of congenital pseudarthrosis of the tibia. The objectives of this study were (1) to examine clinical and radiographic healing after rhBMP-2 application for the treatment of congenital pseudarthrosis of the tibia (CPT) or persistent tibial nonunion in children and adolescents, and (2) to investigate the safety of rhBMP-2 use in these cases...

BACKGROUND: Final fusion is thought to be the end point for patients with early onset scoliosis following treatment with the use of growing rods. But is it? The purpose of this study was to determine the incidence and cause of any reoperation after final fusion. METHODS: A multicenter database of patients with early onset scoliosis was retrospectively analyzed to identify patients treated with growing rods with a minimum of 2 years of follow-up after final fusion...

Congenital pseudarthrosis of the clavicle (CPC) is a very rare condition with a predilection for the right clavicle. Young children are often only symptomatic with activities and as they grow. Operative management in an asymptomatic child is debatable, with various techniques reported in the literature. This is a retrospective, single-centre case series study. All children with CPC treated surgically by resection, bone grafting (nonvascular iliac crest) and plate fixation between 2004 and 2012 at our centre were included...

The off-label use of recombinant human bone morphogenetic protein-2 to promote bone healing in adults has significantly increased in recent years, while reports of recombinant human bone morphogenetic protein-2 application in children and adolescents are very rare. The aim of this study was to evaluate the safety of single and repetitive recombinant human bone morphogenetic protein-2 use in pediatric orthoapedics. Therefore we reviewed the medical records of 39 patients who had been treated with recombinant human bone morphogenetic protein-2 at our institution...

UNLABELLED: A strong relationship between congenital pseudarthrosis of the tibia (CPT) and neurofibromatosis type 1 (NF1) has been suggested, but prevalence varies widely throughout the literature and the criteria used for diagnosis are very heterogeneous. Literature focus is mainly on treatment and no specific review on the prevalence of NF1 has been published. Based on our own observations, we hypothesized the prevalence of NF1 in patients with CPT to be higher than what is previously accepted...

Radial club hand may be congenital or acquired; radial deviation of the hand is usually found, associated with palmar flexion-pronation and treatment of severe forms of radial club hand is often difficult. Here we present a case of reconstruction of a severe postraumatic radial club hand with a free fibular osteoseptocutaneous flap and Sauve-Kapandji procedure in a 28-year-old man. The patient had a radial deviation of the wrist and right upper limb shortening as a result of an infected pseudarthrosis of the radius...

BACKGROUND: Having observed a tendency towards femoral overgrowth (FO) of the affected limb in children with atrophic-type congenital pseudarthrosis of the tibia (CPT), we aimed to identify the incidence of, contributors to, and patterns of FO among such children. METHODS: We retrospectively evaluated 55 children with CPT, 22 with prepseudarthrosis and 33 with atrophic-type CPT from 1989 to 2012. FO was defined as an affected femoral segment ≥10 mm longer than the contralateral segment...

A 26-year-old male complained of painful clavicles. His medical history included multiple fractures of both clavicles, all treated conservatively. Conventional radiographs revealed a typical shape of both clavicles, suggesting non-union. His extraordinary medical history and non-union of both clavicles led to the diagnosis: 'congenital pseudarthrosis of both clavicles'.

BACKGROUND: In congenital pseudarthrosis of the tibia, use of intramedullary (IM) fixation and autogenous bone graft has long been the standard of care. This study was undertaken to determine whether the addition of rhBMP-2 to this treatment method further enhances healing potential. METHODS: Twenty-one patients with congenital pseudarthrosis of the tibia were evaluated. Fifteen of these patients had neurofibromatosis type 1 (NF1). All had IM fixation and autogenous bone graft, followed by a BMP-soaked collagen sponge wrapped around both the fracture site and bone graft...

The treatment objectives in congenital pseudarthrosis of the tibia are bone consolidation and a restored lower-limb axis. They are difficult to achieve, and various surgical techniques have been described, with varying results in terms of bone consolidation and complications. The present study reports clinical and radiographic results in 3 patients managed by the same original technique of transplantar intramedullary nailing using a custom-made proximal locking nail, without surgical approach or resection of the pseudarthrosis site...

BACKGROUND: The first successful free vascularized bone flap was performed on June 1, 1974 (and reported in 1975), using the fibula. This was followed by the iliac crest based on the superficial circumflex iliac artery in 1975 and then the deep circumflex iliac artery in 1978. METHODS: A total of 384 transfers using fibula (n = 198), iliac crest (n = 180), radius (n = 4), rib (n = 1), and metatarsal (n = 1) were used between June of 1974 and June of 2014 for reconstruction of the mandible (n = 267), maxilla (n = 20), clavicle (n = 1), humerus (n = 8), radius and ulna (n = 21), carpus (n = 3), pelvis (n = 2), femur (n = 11), tibia (n = 47), and foot bones (n = 4)...
