STUDY DESIGN A consecutive series of 52 chordomas of the mobile spine observed over a 50-year period includes a retrospective review of 15 cases treated prior to 1991 and a prospective group of 37 cases treated from 1991 to 2002. OBJECTIVES This series reviews epidemiologic issues as well as clinical patterns of spinal chordomas. We attempt to correlate(More)
Between 1985 and 1990 we treated 11 large segmental bone defects (average 6.7 cm) in ten patients with the Ilizarov technique. Open fractures, type III according to Gustilo, represented the largest group (8 of 11 cases). The average delay before the Ilizarov technique was initiated was 8.9 months. The external fixator was usually maintained for 1 year. Bone(More)
STUDY DESIGN Twenty-one cases of chordoma arising in the mobile spine were retrospectively reviewed. OBJECTIVES All the cases were submitted to oncologic and surgical staging to correlate treatment and outcome. SUMMARY OF BACKGROUND DATA Excluding plasmacytomas, chordoma is the most frequent primary malignant tumor of the spine, occurring mainly in(More)
AIM To compare clinical and radiological results in per- and subtrochanteric fractures' management with 90 degrees blade plate or Gamma nail fixation; an implant allowing early weight-bearing and fracture healing in correct position remains still difficult. METHOD Between 1993 and 1995, 26 patients addressed to our Center for a Kyle IV [1] fracture were(More)
One of the most demanding steps of an intramedullary nailing is the distal locking. The aim of this study is to evaluate clinically and prospectively a new targeting guide. Twenty-five patients were treated consecutively in two different trauma centres (level one and one general hospital) by two different surgeons who were instructed on using the new(More)
PURPOSE To report the middle term results of partial coccygectomy in a consecutive series of 15 patients with chronic coccygodynia. METHODS Fifteen patients with chronic coccygodynia were referred to our outpatient clinics. The patients were investigated with dynamic lateral radiography and magnetic resonance imaging (MRI). We diagnosed a posttraumatic(More)
Sternoclavicular dislocations represent a rare injury. Based on our clinical experience with a patient showing an anterior subluxation after reduction of a posterior traumatic dislocation, we review the literature. The emergent reduction of the dislocation is mandatory, always keeping in mind the potentially devastating neurovascular complications. If the(More)
OBJECTIVE To analyze the use of the gamma nail in the treatment of pertrochanteric fractures. DESIGN Prospective. SETTING University. PATIENTS Sixty-three fractures in sixty-three patients treated with gamma nails. RESULTS Forty-five of the sixty-three patients (71 percent) were followed until the end of treatment, for an average follow-up period of(More)
INTRODUCTION Periprosthetic femur fracture (PFF) is a serious complication after total hip arthroplasty that can be treated using different internal fixation devices. However, the outcomes with curved non-locking plates with eccentric holes in this indication have not been reported previously. The objectives of this study were to determine: (1) the union(More)
A group of nine patients with a diaphyseal fracture of the humerus and treated with retrograde nailing were studied with a mean follow-up of 15.3 months. Six patients with a humeral fracture without neurological deficit showed a good shoulder and elbow mobility at the last visit. Three patients with neurological lesion preoperatively suffer from a(More)
