[Clinical and radiologic skills for fracture management. Multicenter study at orthopedics residents].

Background: There is a shortcoming in the diagnostic integration of the mechanism of injury and the radiographic findings. This leads to diagnostic errors and a poor surgical planning with labor and legal repercussions. The purpose is to find out which is the prevailing clinical skill in various Orthopedics residencies by applying a measurement tool prepared ex profeso.

[Treatment of recurrent giant cell tumor of the tibia with en bloc resections, bone transport and arthrodesis using an AO type external fixations system. A case report].

Introduction: The primary treatment for the giant cell tumor (GCT) at the knee level, both distal femur and proximal tibia remains curettage and application of methyl methacrylate. In the cases where recurrence occurs, controversy exists in the decision making algorithm whether to preserve the joint, or to perform en bloc resection.

Case Report: We report a case of GCT that relapsed at proximal tibia in a stage III of Enneking, in a 26 year old patient, that was handled with en bloc resection, transportation and bone arthrodesis using an AO type tubular external fixator (Synthes).

[Fracture due to bilateral avulsion of the tuberosity of the shin bone (tibia). A case report].

Introduction: The avultion-fracture of the tibial tuberosity is a rare injury, one which appears in adolescents, predominantly male and happens in a zone in which the conditions of bone immaturity are favorable, so that an abrupt traction of the patellar tendon generates the injury. The reports of simultaneous fractures in both knees are rare.

Clinical Case: A 14-year-old masculine patient, who had suffered indirect trauma in both knees while playing soccer.

[Treatment of traumatic clavicular pseudoarthrosis with the Hunec Colchero nail].

Introduction: Post-traumatic clavicular pseudoarthrosis occurs as a complication of mid third fractures, particularly of those with an important displacement that leads to failure of conservative treatment. Most reports on the management of this complication use various plates and grafts. We used the Hunec nail as an implant and an iliac crest graft.
