Abstract
The incidence of proximal humeral fractures in children represents about 2% of all pediatric fractures, with a peak incidence between 11 and 15 years of age. Although most pediatric proximal humeral fractures can be successfully treated conservatively with satisfactory results, many operative techniques have been described for the treatment of displaced proximal humeral fractures, including Kirschner (K) wires, screws, and elastic nails. Insertion of the elastic nails through a window in the distal humerus carries the risk of heterotropic ossification at the site of wire insertion and loss of elbow extension. Fixation with straight K-wires results in poor rotational stability and it is sometimes difficult to engage both the proximal and distal fragments. This study was conducted at Mansoura University Hospitals aiming to evaluate the results of treatment of displaced proximal humeral fractures in children by the modified palm tree technique. We included a total of 19 pediatric cases in the current study. All cases were subjected to complete history taking, clinical examination, along with routine laboratory and radiological investigations. Following that, all cases underwent the modified palm tree technique under general anesthesia. Our results showed the following findings : - The mean age of the included cases was 10.21 years (range, 7 – 14.5). - Most of the included cases were boys, who represented 68.42% of cases, while the remaining cases were girls (31.58%). - The left arm was affected in 11 cases (57.89%), whereas the remaining cases had the fracture in the right arm. - Falling on an outstretched hand was the commonest mechanism of injury (73.68%), while the remaining fractures were caused by direct blow to the shoulder (26.32%).
