Even though the elbow is the most often dislocated joint in children, this injury accounts for 3-6 % of elbow pathology. Dislocations without associated fractures are extremely rare. They result from a fall onto an outstretched hand. The patient is always referred with a painful joint, movement impairment and even clinical deformity. Acute treatment aims to achieve quick reduction and adequate joint stability, avoiding neurovascular injuries. We sought to analyze the functional outcomes and the complications after non-operative treatment. Our 4 patients Luxaciones puras de codo en pacientes pediátricos: tratamiento conservador y complicaciones asociadas a una patología poco prevalente. Serie de 4 casos Isolated elbow dislocation in pediatric patients: non-operative treatment and complications associated with an infrequent pathology. Series of 4 cases had excellent functional results at the latest follow-up, and one of them suffered from a median nerve palsy without further consequences. In our experience, these injuries presented excellent outcomes and we would like to highlight the importance of a quick and precise neurovascular examination with the possibility of non-surgical management of nerve injuries. A short period of immobilization with early rehabilitation should be indicated to avoid joint stiffness., Competing Interests: None, (Sociedad Argentina de Pediatría.)

Introduction: Femoral neck fractures have been historically diagnosed by anteroposterior (AP) and lateral (L) radiographic views. We analyzed the importance of the L view for management of femoral neck fractures, using the Garden's classification system., Materials and Methods: Slides were elaborated with AP and L radiographic views of 100 patients with femoral neck fractures admitted to our emergency department. Three hip surgeons assessed independently AP views only and then AP and L views together using Garden's classification system., Results: No statistically significant differences (Kruskal Wallis 0, p=1) were found while comparing categories among Garden's classification system, after assessing L views. There was an 81 % (p < 0.001) agreement of Garden category between AP and AP combined with L views. When analyzing patients with changing categories between displaced and non displaced after assessing L view images, we found a 5% (n=5, CI 95% 1-11%) of change. For comparing AP Garden with L view Garden, we used a quadratic weighted kappa method., Conclusions: There is a high agreement in the Garden category when comparing AP with combined AP and L observations. Five patients would have received a different surgical treatment dependent on the hip surgeon who assessed the radiographs. This highlights the relevance of routinely L radiographs whenever a femoral neck fracture is suspected., (Universidad Nacional de Córdoba)

Introduction: Femoral fractures in previously amputated patients (PAP) have been poorly reported in international literature, however it is worth mentioning that advances in the manufacture of orthotics for lower limbs have allowed these patients to remain functionally active. Surgery is then an option but difficulties may appear in positioning the patient for surgery due to the absence of the foot or ankle from where to pull and optimize the fracture reduction., Objective: We report 3 cases of PAP with ipsilateral unstable femur fractures, treated surgically with cervicodiaphyseal endomedular nail. The surgical technique used in each case is described., Results: Good long-term results were obtained demonstrating the effectiveness of surgical treatment and the reduction technique used., Conclusion: Surgical treatment of unstable fractures of the proximal femur with an endomedullary nail should be considered a valid therapeutic option., (Universidad Nacional de Córdoba)
