Interlocking intramedullary nailing currently is the preferred treatment for most tibial fractures requiring operative treatment. Good results with a relative low complication rate have been reported in large clinical series, as well as in comparative series. The reported incidence of neurological complications after tibial nailing varies, involving mainly the peroneal nerve. The mechanism of peroneal nerve damage in tibial fracture nailing is usually indirect, caused by leg traction or compartment syndrome. Direct peroneal nerve damage related to the proximal locking screw seems to be very rare since we were able to identify only one report in the English literature. We report a case of partial peroneal nerve damage caused by a long oblique proximal locking screw. Removal of the proximal locking screw leaded to a gradual improvement of the nerve function and a complete resolution at one year. This seems to be a new emerging iatrogenic complication related to nails designed with oblique proximal locking screws. We feel that the placement of the oblique proximal screw from medial to lateral side needs an extra care. Even fluoroscopy, does not give enough safety due to the spatial geometry of the proximal tibia and the known problems of viewing oblique interlocking screws with a two-dimensional image-intensifier.
