Multicenter Study
[Pelvic fractures: epidemiology, therapy and long-term outcome. Overview of the multicenter study of the Pelvis Study Group].
Pelvic fractures are rare injuries (3-8%) when compared to fractures in other body regions. They are accompanied by high mortality (5-20%), and the survivors suffer from severe pain and pelvic-related handicaps. The German Pelvic Group (German Chapter of the AO-International & German Trauma Society) started a prospective multicenter study, including ten major trauma centers for collecting a high number of data in a short period of time (1991-1993). ⋯ Although progress in indications and treatment techniques has shown improved radiological results after unstable pelvic ring injuries when compared to earlier studies, the clinical result still remains unsatisfactory. Further analyses and studies must be conducted to identify the prognostic factors for the late sequelae. Whether it is possible influence these factors by additional surgical intervention cannot be answered at present.

Review Multicenter Study[Fractures of the anterior rim of the distal part of the tibia. Apropos of a series of 38 cases].
Fracture of the anterior rim of the distal tibia is a rare injury. This fracture seems less serious than other pilon fractures but its treatment is often difficult and didn't give better results. The aim of this study was to describe problem we dealed with and to suggest solutions in order to improve long term results. ⋯ Better results should come from a better analysis of the bone lesions : separation, impaction or mix fracture. This analysis leads to appropriate surgical procedure which give back a stable and anatomic distal tibia. External fixation can be usefull for immobilization ; this can't avoid open reduction and internal fixation of the fracture. Bone grafting can be useful for impaction fracture.

Multicenter Study
[Femoral neck fractures in adults: joint sparing operations. I. Results of an AO collective study with 328 patients].
In a multi-center study in 14 trauma hospitals 328 patients with fractures and osteosyntheses of the femoral neck were investigated with reference to time between accident and operation implants used, early and late complications, and results in the years from 1974 to 1987. A follow-up examination was possible in 266 patients a mean of 46.7 months after their accidents. General postoperative complications were recorded in 12.2% and local complications in 11.6%. ⋯ The best results (significantly better than in other groups) were obtained in patients who were operated on early (< 24 h after trauma) (P < 0.05) and those in whom dynamic hip screws (DHS) were used (P < 0.01). Of all cases of aseptic necrosis 70% were seen within 3 years and 86% within 6 years after trauma. The rate was dependent on the degree of dislocation of the fracture (Garden III and IV), the time from trauma to operation, and the implant used (130 degrees blade plate 30.5%, DHS 9.2%).

Multicenter Study Clinical Trial
The treatment of open and/or unstable tibial fractures with an unreamed double-locked tibial nail.
A multicenter, prospective study was conducted to assess the efficacy of an unreamed, double-locked tibial nail for the acute management of open and/or unstable tibial fractures. Seventy-seven acute unstable and/or open tibial fractures in 74 patients were treated from December 1986 to February 1989. Forty fractures were closed and 37 were open; 25% occurred in polytraumatized patients and 39% of the patients had additional fractures. ⋯ Difficulty was encountered with proximal screw insertion in one third of the cases. Considering the high energy of these injuries, the treatment of open and/or unstable tibial fractures with an unreamed, double-locked tibial nail can offer the surgeon a high rate of union (97%) with minimal complications. The low infection rate found in this series indicates that this nail may be of particular benefit in the treatment of closed and select open tibial fractures.

Multicenter Study Clinical Trial
[Pelvic fractures in the Kiel trauma surgery clinic. A one-year evaluation].
48 injuries to the pelvis were treated from January 1991 through December 1991. We found 45 fractures of the pelvic ring with associated acetabular fractures in 15 cases and three isolated acetabular lesions. 19 injuries were caused by car accidents, 18 fractures resulted from a fall, especially in older patients. Isolated fractures of the pelvis occurred in 18 cases. ⋯ There were 14 cases in which we found sacral fractures as an additional dorsal lesion. Nine of 14 sacral fractures were recognized only by CT examination. In eleven cases the conventional radiographs showed simple anterior pelvic ring fractures while the CT examination revealed an additional lesion of the sacroiliac joint in nine of these cases.(ABSTRACT TRUNCATED AT 250 WORDS)
