Pyomyositis of the inner thigh muscles due to Escherichia coli in a young patient with severe aplastic anemia.

Pyomyositis, an acute bacterial infection of skeletal muscle, is caused by Staphylococcus aureus or other gram-positive organisms in >90% of cases. A 19-year-old boy with severe idiopathic aplastic anemia presented a pyomyositis of inner thigh muscles due to Escherichia coli as a complication of his underlying disease. The diagnosis was established by means of soft tissue ultrasound, magnetic resonance imaging (MRI) and blood culture.

Iatrogenic femoral neck fracture during closed nailing of the femoral shaft fracture.

Background: Intramedullary nails have become a popular implant in the management of femoral shaft fractures. The occurrence of a femoral neck fracture after closed intramedullary nailing is an exceptional complication of this technique that has been rarely reported in the literature.

Methods: We report a retrospective study to identify the possible causes that could produce a fracture of the femoral neck after nailing of the ipsilateral femur.

Direct repair of spondylolysis using a new pedicle screw hook fixation: clinical and CT-assessed study: an analysis of 19 patients.

Objective: A prospective analysis of 19 consecutive cases of spondylolysis repair using a new hook screw device is presented. The objective of the study was to assess the clinical, radiologic, and computed tomography (CT) scan outcomes to establish the indications of isthmic repair in the treatment of spondylolysis.

Methods: Nineteen patients treated with a new segmental pedicle screw hook fixation were followed up for a minimum of 2 years (mean 30 months, range 24-48 months).
