[Foreign body retained within ulnar nerve in the distal humerus]. / Einsprengung eines metallischen Fremdkörpers in den N. ulnaris am Oberarm.

This report describes the procedures applied to remove a metal foreign body retained inside the ulnar nerve in the distal humerus of a 49-year-old patient. Exemplified by an unfavorable primary treatment this article presents the first description of removal of an foreign body retained within a nerve whereby emphasis is placed on the problems associated with the preoperative and intraoperative localization of the foreign particle.

[Multidimensional corrective osteotomy of the distal femur using a retrograde femoral nail]. / Mehrdimensionale Korrekturosteotomie des distalen Femur unter Verwendung des retrograden Femurnagels.

We report the case of a 62-year-old woman with marked valgus and limitation of extension of the right knee joint as the result of a supracondylar fracture of the femur, originally treated by internal fixation with a dynamic condylar screw. Two years later, revision osteotomy with retrograde femoral nailing was carried out to achieve variation and improve extension. Within a week of operation the patient's right leg was fully weight bearing with normal axial positioning. A retrograde locking nail provides satisfactory and stable internal fixation in cases of revision.
