Gnathodiaphyseal dysplasia (GDD) is a rare skeletal syndrome that involves an osteopetrosis-like sclerosis of the long bones and fibrous dysplasia-like cemento-osseous lesions of the jawbone. Although the genetic analysis of the respective patients has revealed mutations in the ANO5 gene as an underlying cause, there is still no established consensus regarding the bone status of GDD patients. We report a new case of GDD in a 13-year-old boy with recurrent diaphyseal fractures of the femur, in whom we identified a novel de novo missense mutation in the ANO5 gene, causing a p...

BACKGROUND: Ipsilateral femoral neck fractures occur in 1% to 9% of adult trauma patients with femoral shaft fractures making dedicated imaging important. This is not as clear in children. Our purpose is to establish the incidence of ipsilateral femoral neck fractures in children with femoral shaft fractures and to provide recommendations regarding diagnostic imaging protocols. METHODS: A retrospective analysis of medical records was performed for pediatric patients (below 18 y) with femoral shaft fractures seen at our trauma center over a 10-year period...

BACKGROUND: Management of fibrous dysplasia of the proximal femur is a progressive, often recurrent condition of bone that can cause skeletal deformity, fractures, and pain. Allogeneic cortical strut grafting to minimize the risk of fracture or as part of fracture treatment is a promising treatment option, but evidence is scarce on the intermediate- to long-term results of this procedure and there are no data on factors associated with graft failure. QUESTIONS/PURPOSES: The purposes of this study were (1) to evaluate the revision-free survivorship; (2) radiographic findings; (3) factors associated with failure; and (4) complications associated with cortical strut allograft to prevent or treat fractures of the proximal femur in patients with fibrous dysplasia...

Falls are the leading cause of accidental death among the elderly, accounting for about 12 000 deaths per year. The risk of falls increases with age: one-third of subjects over 65 years old living in the community and half of those over 85 fall at least once a year. Despite their frequency, falls should not be trivialized, as they are associated with significant morbidity and care expenditure: 10% of falls have severe traumatic consequences, and30 % of hospital admissions for traumatic injury among elderly individuals are due to falls...

Fibrocartilaginous dysplasia (FCD) is a rare variant of fibrous dysplasia (FD) which frequently involves the long bones, and the proximal femur is the most commonly affected site. This benign, lytic, and expansile bone lesion causes progressive deformity in the bones and may lead to pathological fracture. Radiologically, this lesion may mimic cartilaginous benign and malignant bone tumors. Therefore, histopathological differentiation of FCD from other cartilaginous tumors is of the utmost importance. The treatment is often surgical, in the form of curettage and bone grafting or corrective osteotomy, to treat progressive deformity in the long bones...

Scurvy is a rare disease in developed countries. Risk groups include children with restricted diets, mainly patients who are autistic or have cerebral palsy. Furthermore, consumption of plant-based beverages has increased in recent years, especially in developed countries. When plant-based beverages are the exclusive diet in the first year of life and not consumed as a supplement to formula or breastfeeding, it can result in severe nutritional problems. We report a case of scurvy after exclusive intake of almond beverages and almond flour from 2...

Maffucci syndrome, a rare sporadic form of enchondromatosis, is characterized by hemangiomas and multiple enchondromas, benign cartilaginous tumors that arise near growth plates. Previous studies demonstrate that individuals diagnosed with Maffucci syndrome have approximately 100% lifetime risk of malignant transformation. Identification of Maffucci syndrome by surgical excision and pathological diagnosis can be life-saving due to its high malignant potential relative to other subtypes of enchondromatosis such as Ollier's disease...

Pathological and metabolic bone diseases are common and relevant occurrences in orthopedics and trauma surgery; however, fractures are often treated as being the illness itself and not seen as the symptom of an underlying bone disease. This is why further diagnostics and systemic treatment options are often insufficiently considered in the routine treatment of fractures. This review focuses on osteoporosis, osteopetrosis, hypophosphatasia and Paget's disease of bone.In patients with osteoporotic vertebral or proximal femur fractures, pharmaceutical treatment to prevent subsequent fractures is an integral part of fracture therapy together with surgical treatment...

Hydatid disease is caused by the parasitic tapeworm Echinococcus granulosus. Osseous involvement accounts for 0.5% to 4% of cases in humans. Patients usually are from endemic zones and are initially asymptomatic, presenting with pain and edema at a later stage of disease. However, large lesions may present initially as pathologic fractures. Standard radiographs usually show expansive osteolytic lesions associated with initial cortical thinning, with compromise of the metaphysis or epiphysis, and may involve the diaphysis...

Trauma is a significant health problem and a leading cause of death in all age groups. Pain related to trauma is frequently severe, but is often undertreated in the trauma population. Opioids are widely used to treat pain in injured patients but have a broad range of undesirable effects in a multitrauma patient such as neurologic and respiratory impairment and delirium. In contrast, regional analgesia confers excellent site-specific pain relief that is free from major side effects, reduces opioid requirement in trauma patients, and is safe and easy to perform...

Despite the case of a 19-year-old male with a pathological subtrochanteric left femoral fracture in the course of an extensive arteriovenous malformation of the left thigh. The arteriovenous malformation was diagnosed when the patient was 16 years old. He has undergone several embolization procedures. The fracture was caused by a fall from the patient's own height. Before the patient was qualified for surgery of the fracture, a left lower limb angiography confirmed the presence of extensive pathological vascularity (arteriovenous malformation), and an embolization procedure was performed on the branches and trunk of the left deep femoral artery, several vessels branching off of the proximal and distal segment of the superficial femoral artery and one branch of the internal iliac artery...

Loeys-Dietz syndrome (LDS) is a connective tissue disorder characterized by vascular and skeletal abnormalities resembling Marfan syndrome, including a predisposition for pathologic fracture. LDS is caused by heterozygous mutations in the genes encoding transforming growth factor-β (TGF-β) type 1 and type 2 receptors. In this study, we characterized the skeletal phenotype of mice carrying a mutation in the TGF-β type 2 receptor associated with severe LDS in humans. Cortical bone in LDS mice showed significantly reduced tissue area, bone area, and cortical thickness with increased eccentricity...

We describe a case of a 59-year-old woman with a medical history of upper leg pain and chronic lymphatic leucaemia (CLL), with known diffuse bone marrow infiltration and without signs of lymphatic or extra-lymphatic disease activity on positron emission tomography CT (PET-CT). She presented with multiple fractures of the pelvis, sacrum and left proximal femur as a result of a low energy fall. During admission, she sustained a non-traumatic fracture of the right proximal femur. Pathological fractures in patients with CLL are usually based on Richter's transformation or multiple myeloma...

Nowadays, women with genital cancers live longer due to early diagnosis and better treatment schemes. Only few studies assessed bone mass in patients with genital cancer Osteoporosis is a condition characterized by progressive loss of bone mass, weakening of the spatial structure of the bone, and increased susceptibility to fractures. Osteopenia is a condition of reduced, but not yet reaching the pathological values, bone density in relation to norms for age and sex. Metastases are the primary cause of death in cancer patients...

INTRODUCTION: There is no consensus on when and how to treat unicameral bone cysts (UBCs), partly because of a lack of knowledge of the aetiology. PURPOSE: To review the different treatment techniques for UBCs and to describe our results with a single injection of autogenous bone marrow (BM) mixed with demineralised bone matrix (DBM) in very young children. PATIENTS AND METHODS: We reviewed five patients under the age of 8 years with UBCs treated by percutaneous aspiration and a single injection of BM associated with DBM...

Brown tumors result from excess osteoclast activity and consist of collections of osteoclasts intermixed with fibrous tissue and poorly mineralized woven bone. They are secondary to hyperparathyroidism (HPT). Their incidence is higher in primary than in secondary hyperparathyroidism. We report a 69 years-old male, admitted in a state of confusion, lethargy and bedridden, with a pathological fracture of the femur caused by a brown tumor. The laboratory examination revealed a hypercalcemia (8.85 mEq/L), with high levels of ionized Ca (5...

Hedgehog (Hh) signaling plays important roles in various development processes. This signaling is necessary for osteoblast formation during endochondral ossification. In contrast to the established roles of Hh signaling in embryonic bone formation, evidence of its roles in adult bone homeostasis is not complete. Here we report the involvement of Gli1, a transcriptional activator induced by Hh signaling activation, in postnatal bone homeostasis under physiological and pathological conditions. Skeletal analyses of Gli1+/- adult mice revealed that Gli1 haploinsufficiency caused decreased bone mass with reduced bone formation and accelerated bone resorption, suggesting an uncoupling of bone metabolism...
