Comparative Study
[The femoral neck fracture in the elderly patient - cemented or cementless hip arthroplasty?].
This is a report on the treatment results of femoral neck fractures with a cemented (group 1) and cementless (group 2) type of hip prosthesis, resp. 72 patients were enrolled. 35 patients were treated with a cemented hip prosthesis (mean age: 78 years), and 37 patients with a cementless modular hip prosthesis (mean age: 77 years). In the cemented group we observed 5 cases of hypotension during insertion of the prosthesis in the femoral shaft. One of these patients required mechanical resuscitation during surgery. ⋯ No prosthesis loosening was observed in either group. In our view the cemented hip prosthesis is the treatment of choice for femoral neck fractures among the old and very old, if no stabile osteosynthesis can be performed. Patients with cardiopulmonary risk factors, however, may profit from cementless hip arthroplasty to avoid the well known cardiodepression during surgery.

Comparative Study
[Surgical treatment of fractures of the clavicle--Indication, surgical technique and results].
46 cases of clavicular fracture (25 of the middle third and 21 of the distal third) are reviewed concerning indications for surgery, surgical technique and postoperative results. In 32 cases surgery was necessary due to dislocation (in 7 cases with a rupture of the coracoclavicular ligaments), 3 times due to a complex trauma of the shoulder joint, 3 times due to a local neurovascular involvement, 3 times due to a delayed fracture healing and 3 times due to a pathological fracture. In two cases an open fracture required osteosynthesis. The most frequent surgical procedure was plate osteosynthesis using the following materials: 3.5 mm LCDC plate, the so called "Balser plate" and the "Ulrich plate", 3.5 mm reconstruction plate, 3.5 mm T-plate and compound plate. In 14 cases autogenous bone grafting was performed. Additional suture of the coracoclavicular ligaments was indicated in 7 patients. In every case early physiotherapy followed the surgical procedure. ⋯ in 2 cases an avascular pseudarthrosis emerged after plate osteosynthesis without autogenous bone grafting. In one case a non-union developed due to infection. Moreover we found a loosening of a "Balser plate" and in one patient the development of keloid tissue. The functional outcome according to the Constant score was good. 32 patients achieved 89 out of 100 possible points (average follow up 31 months). In distal clavicle fractures we prefer the use of the "Balser plate" combined with a suture of the coracoclavicular ligaments. Due to the occurrance of delayed fracture healing with pseudarthrosis (2/25) in fractures of the middle third, the indication for surgical treatment has to be discussed. In case of local soft tissue trauma and damage of the periostal blood supply, plate osteosynthesis in combination with autogenous bone grafting should be performed.

The importance of laparoscopy in the management of blunt abdominal trauma should be evaluated. Therefore we retrospectively analysed all patients with blunt abdominal trauma treated in the Department of Surgery at the Carl-Thiem-Hospital Cottbus between 1998 and 2000. ⋯ The percentage of so called "negative" exploratory laparotomies within this study was 13.2 %. Our analysis suggests that laparoscopy should become firmly established in the diagnostic management and, if indicated, in the treatment of blunt abdominal trauma as well.
