Fractures of the radial neck accounts for 1% of all childhood fractures and 5% to 10% of childhood traumatic lesions involving the elbow. Intramedullary percutaneous nail reduction (Metaizeau technique) is considered the most effective surgical technique. The purpose of this study was to identify the main clinical features of radial neck fracture in children and to evaluate the anatomical and functional results of the Metaizeau technique. In this retrospective study, we evaluated 22 patients under the age of 16 who were treated for radial neck fracture at the orthopedic and trauma surgery department of Sahloul University Hospital in Sousse over a period of 16 years from January 2001 to April 2017. Authors used Metaizeau classification. Functional results were evaluated by Mayo elbow performance score (MEPS) and the radiological evaluation was based on standard images with measurement of the residual rocker. The average age was 8.6 years (5-13 years). Seven fracture were grade III injuries and three grade IV. In the immediate postoperative period, radiological measurements showed a residual rocker less than 20° in 86.3% and more than 20° in 13.7% of cases. At an average follow-up of 13 months and a half, the MEPS score was excellent and good for 17 patients. Four types of complications were found: necrosis of the radial head in 1 case, pseudarthrosis in 1 case, periarticular calcification in 2 cases and stiff-ness of the elbow in 3 cases. Despite the small number of patients in our series, we believe that the elastic stable intramedullary pinning according to the Metaizeau technique is the treatment of choice for displaced radial neck fractures in children.

Abstract:Hidradenitis suppurativa is a chronic, recurrent inflammatory disease affecting the cutaneous apocrine glands and resulting in their obstruction [1]. This enigmatic disease causes recurrent episodes of infection, edema, scarring, and fibrosis of surrounding tissues. We present the unusual case of a 58-year-old white male with fifteen years of hidradenitis suppurativa (HS) complicated by the occurrence of penoscrotal elephantiasis.

Aneurysm of the renal artery is a rare condition with relatively uncommon symptoms. A 58-year-old male patient presented to the emergency department with urinary retention caused by massive hematuria. He was hemodynamically stable, and Ultrasound examination of the abdomen showed a massive clot of blood in the bladder with no signs of tumor. Multi-detector CT images in the arterial phases showed bleeding in the left renal pelvis and an intra-renal lower pole aneurysm. The CT findings were consistent with a rupture of the aneurysm into the left renal pelvis. The aneurysm was embolized with a coil. Immediate post-interventional checkup injections revealed no sign of renal aneurysm. One month later, clinical follow up revealed no hematuria.
