[Initial results with the ball joint fixator].

The ball-joint fixator is a one-plane external fixator system that allows correction of the reduction postoperatively. Dynamic axial loading is made possible by a telescoping device. Between January 1987 and June 1991, 312 external fixators were applied in the Department of Trauma of the Surgical University Clinic in Freiburg/Breisgau. In 25 of these cases the ball-joint fixator (Unifix) was used. The study includes 16 open and 8 closed tibial fractures and 1 open femoral fracture. The pin-tract infection rate was 14%. In 16 patients a cast was necessary for a short time after the fixator had been removed, and 3 other patients needed intramedullary nailing. The long-term complications observed were osteitis pseudarthrosis and refracture (in 1 case each). The ball-joint fixator is a device that can be applied very easily and quickly. It can be used to advantage in the treatment of multiple trauma patients with open tibial fractures. Because of the fixed distance between the pin clamps there is no advantage over the original AO fixator in fractures where the telescoping mechanism cannot be used.

[Traumatology in the elderly. Treatment concept in per- and subtrochanteric fractures in the elderly].

The aim of treatment of trochanteric fractures in the elderly patient is a prompt procedure, which allows early load bearing. Between 1986 and 1988 272 patients were treated with per- and subtrochanteric fractures: pertrochanteric fractures were stabilised by means of the dynamic hip screw (DHS), subtrochanteric fractures via the 95 degree condylar plate. With both methods an early mobilisation of the patients is possible. In 70 per cent of cases treated with DHS, early load bearing could be achieved within one week. 80 per cent of the patients were operated on within the first 24 hours after trauma. Complications of the methods (incorrect position of the lag screw, plate protrusion) were seen in one case in each group. The overall infection rate was 2.2 per cent. Hospital mortality was 10 per cent. On reviewing the results obtained, we approved of the concept of treatment.

[Early functional treatment of fractures of the lower thoracic and lumbar vertebrae with a 3-point brace].

We describe the concept of early functional treatment for patients with stable fractures of the lower thoracic and lumbar spine. Between 1983 and 1985, 102 patients treated in our department were mobilized after an average of 7 days in the three-point brace, which stabilizes the spine in the correct position. At the same time we begin with physiotherapy, which is continued after discharge from the clinic (after an average of 10 days). Our patients wear the brace for an average of 10 weeks. Moreover, 22 patients were mobilized early without a brace. On follow-up examination of 87 patients after an average of 2 1/2 years we found good or very good results more than 85% of patients in both groups. A little loss of reduction was seen despite the three-point brace, but the "sintering" was a little less pronounced than in patients mobilized early without a brace. Moreover, the brace prevents dangerous movements, so that the patients feel more secure.

[Bicycle accidents--causes and sequelae. An evaluation of the 1986 calendar year].

In a population of 402 motorcyclists and bicyclists, which were treated in the Traumatological Department of the University of Freiburg during 1986, we describe the different cause, spectrum and follow-up of the injuries. The special risk factors are discussed. The social implications show the importance of preventive measures to limit the risk of injury. With respect to the 70% of injured bicyclists with severe head injury, the wearing of safety helmets is strongly advocated. The effectiveness of cycle lanes is substantiated by our results.

[Plate osteosynthesis in femoral shaft fractures].

Between 1979 and 1988, 119 children with 123 femur shaft fractures were treated in the Department of Traumatology of the university-hospital of Freiburg. Traffic accidents were the reason in half of the cases. 19 children had multiple trauma and serious cranio-cervical traumata. In the case of 14 further children, additional limb fractures could be diagnosed, four of which were contralateral femur shaft fractures. More than half of the children with femur shaft fractures were treated by internal fixation. Only internal fixation by plate was employed. 32 children were operated upon at the day of the accident (49%). Children with solitary injuries could be treated as outpatients after 13 days. The implanted material could be removed after an average of 8.4 months. At the moment a reexamination of 31 operated cases (altogether 65 children with 69 fractures are operated) is performed. 30 children have excellent (18 patients) or good (12 patients) results. The healing process was complicated by delayed healing of the fracture (1 patient), plate fracture after 2 months (1 patient) and subcutaneous haematoma (2 patients). Osteitis did not occur.

[Fractures accompanied by injuries of the great vessels in sport and leisure accidents. Diagnosis and management concept].

Extremity fractures with concomitant vascular injuries are surgical emergencies. Especially injuries of the upper extremities require a preoperative angiographic examination for the localization of the vascular lesion. In vascular lesions of the lower extremities a primary angiography is not necessary, if there is an opportunity for an intraoperative radiologic evaluation. In our traumatological department 104 patients were treated over the last 15 years with that combined injury. The concept of immediate stabilization of the fracture with simultaneous or postponed arterial repair has been proved to be appropriate. The fasciotomy as prophylactic procedure of a postischemic compartment syndrome is also a part of our concept during the last years. The late results in our mostly young patients depended on the degree of soft tissue damage and the time of ischemia. The often untreatable nerve lesions contributed to a loss of use of about 30% in the late courses.

[Sprain and dislocation of the hip joint].

Traumatic dislocations of the hip, while very infrequent injuries, must be treated with the utmost urgency. The later the adjustment is made, the sooner aseptic necrosis of the femoral head and periarticular ossification have to be reckoned with; these may lead to dysfunction. The results of 40 cases are reported, one-half of which was treated with two-week extension and a long period of non-weight bearing, the other half without extension, early mobilisation and partial weight bearing up the 11th week. The results in each group are equally good. Thus, we endorse Lorenz Böhler's proposal to follow the immediate repositioning with a short inpatient treatment and early mobilisation, increasing to full-weight bearing after one week and certifying working capability after 3 to 4 weeks.
