Pseudarthrosis development is dependent on the presence of individual risk factors in approximately 10% as a result of fractures and are more frequently located in the region of the long bones. The development of non-union regularly results in prolonged pain and reduced functionality of the affected limb. The resulting clearly increased socioeconomic costs are caused by the complex operative treatment strategies and increased indirect costs, which include lost wages, social benefits and compensation. Altogether, non-unions require a differentiated therapeutic treatment strategy...

Congenital pseudarthrosis of the clavicle (CPC) is a very rare pathology of which over 200 cases have been reported. Usually discovered during the first months of life, CPC is characterised by a definitive bone defect in the middle third of the clavicle. Generally asymptomatic, the pseudarthrosis of the clavicle can cause aesthetic issues and functional symptoms indicating a surgical repair. Different reconstruction techniques have been reported with various complications. We present a 14-year-old boy diagnosed with CPC and concerned about the cosmetic aspect of a swelling of his right clavicle...

Andersson lesion is a destructive vertebral or disco-vertebral lesion that occurs in the late stage of the ankylosing spondylitis. According to the etiology, these lesions are usually classified into localized lesions and extensive lesions. The history of ankylosing spondylitis and characteristic imaging is the key to the diagnosis of Andersson lesion. Conservative treatment may be effective for localized lesions. However, surgical intervention is often required for the failure of conservative treatment and extensive lesions...

Neurofibromatosis type 1 (NF1) is a common genetic disorder caused by mutations in the NF1 gene. Recalcitrant bone healing following fracture (i.e. pseudarthrosis) is one of the most problematic skeletal complications associated with NF1. The etiology of this condition is still unclear; thus, pharmacological options for clinical management are limited. Multiple studies have shown the reduced osteogenic potential of Nf1-deficient osteoprogenitors. A recent transcriptome profiling investigation revealed that EREG and EGFR, encoding epiregulin and its receptor Epidermal Growth Factor Receptor 1, respectively, were among the top over-expressed genes in cells of the NF1 pseudarthrosis site...

Since 1968, many surgical techniques used in repairing the pars defect of the vertebra have been reported. Technological advances are giving rise to new ways of obtaining the best outcome using less invasive methods, which are more accurate, simple and effective. To treat cases of spondylolysis such as pseudarthrosis, we used neuro-navigation and microscopy through a 2.5-cm skin incision to approach the pars defect, freshen the fracture and place a type of screw that, until now, has never been used for this purpose...

PURPOSE: To determine the incidence of pseudarthrosis at the osteotomy site after three-column spinal osteotomies (3-COs) with posterior column reconstruction. METHODS: 82 consecutive adult 3-COs (66 patients) with a minimum of 2-year follow-up were retrospectively reviewed. All cases underwent posterior 3-COs with two-rod constructs. The inferior facets of the proximal level were reduced to the superior facets of the distal level. If that was not possible, a structural piece of bone graft either from the local resection or a local rib was slotted in the posterior column defect to re-establish continual structural posterior bone across the lateral margins of the resection...

INTRODUCTION: The SOFCOT symposium (2005) on periprosthetic fractures of the femur (PFFs) highlighted a high rate of dislocation (15.6% at 6 months) after change of prosthesis. So far, no study has ever proved the benefit of dual-mobility articulation during PFFs revisions. We conducted a comparative study on two prospective cohorts in order to (1) assess the influence of systematic acetabular revision in favor of a double mobility on dislocation rate (2) and in order to evaluate the rate of morbidity associated with this extra surgical procedure...
