[The urgency of special x-ray control in the conservative treatment of femoral fractures in childhood].

The conservative treatment of fractures of the shaft of the femur by extension according to Weber has been successful with children. It is simple to position the young patient on the so called "Weberbock", the position of the fragments can be always controlled radiologically, and if necessary, it can be corrected. But recent investigations have shown, that in some cases false torsions are corrected spontaneously.

[The dynamic condylar screw (DCS) in proximal femoral fractures. Initial experiences].

Beginning January 1st 1987 19 fractures of the proximal femur were stabilized utilizing the "dynamic condylar screw" (DCS). During or after reduction of the fracture the DCS is accomplished by a supporting plate. In the cases we applied the DCS hitherto employment of a bone distractor of complementary cancellous bone graft has been mandatory. Although we feel encouraged by our preliminary results the DCS will have to undergo arduous clinical trial.

A method for fixation of femoral fractures below previous hip implants.

Previously applied plates and screws or endoprosthetic implants of the proximal femur create a recurrent problem in surgery for fractures below such implants. Of 13 elderly women (mean age, 81 years) six had had a hip arthroplasty, five a nail and plate, and two a nail or a plate only. The fresh fractures were stabilized from the condylar region by intramedullary nails connected to a coupling-piece with two transverse screws preventing extrusion or intrusion of the nails. All fractures healed uneventfully without rotatory and angulatory malalignment. The maximum shortening was 2 cm in two patients and was less in the others. Patients walking before surgery were mobilized the day after. The system is more stable than Rush pins or Ender nails only and does not require good quality of bone needed for plating.

[Calculation of the true angle in malposition of the skeletal system using electronic data processing. Retrospective study of 53 axis deviations in healed femoral fractures].

Under standard conditions deformations in the skeletal system are diagnosed by two X-ray photographs whose planes of projection form a right angle. The degree of deviation from the axis is measured directly on the X-ray photograph with a protractor. The analysis of the position of the axis of a tabular bone is carried out by determining the varus/valgus or ante/recurvation deformities resp. in the a.-p. and lateral rays. The degree of deformation is expressed through the supplementary angle. We asked ourselves whether a diagnostic procedure using X-rays taken in two planes is suitable for substantiating the evidence of a deformation of the axis. Example: If a fracture of the lower leg shows a varus deformity of 20 degrees in the a.-p. and a normal position of the axis in the lateral photograph, the actual angle is 20 degrees. This situation is an expection in that most cases the defect of the axis is a so-called combined defect (dislocation from the axis in both planes). In this case it can maintained that the measurable angle of deviation in the a. -p. and lateral X-ray photographs is smaller than the angle that is actually included by both fragments. We call this angle true angle. If you think of a fractured tubular bone as a cylinder it can be shown in a diagram that its deformation can only occur in one plane (Figure 1). Only from the perspective of a ray falling vertically on the curve k we would be able to determine the true angle directly from the photograph with a protractor.(ABSTRACT TRUNCATED AT 250 WORDS)

Surgical repair of a comminuted distal femoral fracture in a dog.

This case illustrates that good results may be achieved with fractured femur that was severely comminuted (i.e. a "Humpty Dumpty" fracture). The blood supply at the fracture site must be carefully preserved. The bony architecture must be reestablished with perfect reduction of the articular surfaces, preferably with interfragmentary compression between the bone fragments. These fragments are held in place with screws and Kirschner wires. Some of the screws and pins were left in place as the trauma incurred to retrieve them would have done more harm than good due to bony overgrowth.

[Complications of plate osteosynthesis of femoral fractures].

Although the introduction of the locking pin in the management of upper thigh fractures has widened the range of possible indications for intramedullary fixation, there are still cases where the DCP technique is applied. When using DCP, it is essential that the graft chosen has the appropriate length and that great attention is given to correct technique, because plating is still associated with a higher complication rate than intramedullary fixation.

Treatment of distal femoral fractures with intramedullary supracondylar nails in elderly patients.

30 acute fractures of the distal femur in 29 elderly patients were treated with a Russell-Taylor intramedullary supracondylar nail (IMSC). 26 of the 30 fractures (87%) united in 2-8 months. Two patients died before fracture union for reasons unrelated to the fracture. Two patients were reoperated upon, in one case the fracture was not adequately reduced at the first operation; in the other patient the nail broke 4 months after operation. In all patients knee flexion reached at least 90 degrees. No infections or thromboembolic complications were seen. The IMSC nail provided the necessary stable fixation with only a few complications in this group of elderly patients without the need to prolonged immobilisation.

Death after proximal femoral fracture--an autopsy study.

We reviewed 22,486 consecutive autopsy reports in a single District General Hospital, from 1953 to 1992. Five hundred and eighty-one patients with fractures of the proximal femur (hip fracture) were identified. Causes of death were correlated with timing of surgery and change of clinical practice. Thromboembolic and haemorrhagic potential were analysed. The principal causes of death after hip fracture were bronchopneumonia, cardiac failure, myocardial infarction and pulmonary embolism. Surgical intervention, within 24 h of injury significantly reduced death from bronchopneumonia and pulmonary embolism. Early mobilization reduced death from bronchopneumonia. Pulmonary embolism may be reduced by prophylactic anticoagulation, but 17 per cent of patients are at risk of haemorrhage, and mechanical methods seem safer in this population.

Management of periprosthetic femoral fractures.

We followed up 37 periprosthetic fractures to assess the factors related to the outcomes and the loosening of prostheses. The average union time is 3.1 months (range, 2-6.2 months). The most common types were fractures around the stem tip and displaced (89.1%). In our study, the loosening rate (32.4%) was low compared with other reports. These might be due to the cementless stem, but the difference was not significant (P>.05). After management of the fracture with a plate, we noted 5 complications: 2 nonunion and 3 refractures. The causes of these complications were related to screw in the level of the stem tip. Therefore, in the management of fractures with plates, we do not recommend using a screw in the area of the stem tip but rather using a cerclage proximally and bone graft. If stem was unstable or stability was uncertain, and the arthroplasty did not function well previously, revision with a distal fluted stem showed an early bony union.

[406 femoral fractures in children].

406 fractures of the femur in persons younger than 17 years of age were treated at Haukeland University Hospital, Bergen, from January 1980 to December 1993. The incidence was 35/100,000 per year; 57/100,000 for boys, and 24/100,000 for girls. No significant changes in the incidence occurred during the study period. 70% of the fractures occurred in boys. 78% had an isolated fracture, while 7% had other fractures, 7% head injuries and 8% injuries of multiple organs as well. Traffic accidents accounted for 35% of the fractures. 65% of the femur fractures were treated by skeletal traction (mean hospitalisation 30 days), 21% were operated on initially (hospitalisation 12 days), and 14% were given early spica cast (hospitalisation three days). The results of the treatment were generally satisfactory. Neither anisomelia (8.5% more than 10 mm) nor malrotation (12% more than 10 degrees) of the femur was a serious problem, but the length of time the patients were hospitalized was rather long.

Determination of osteoporosis in patients with fractured femoral neck using the Singh index: a Jerusalem study.

The Singh index was used to measure the degree of osteoporosis in patients with fracture of the neck of the femur and to compare its prevalence with a random population sample in Jerusalem. The frequency of osteoporosis was 22.7% among women in the fracture series as compared with 1% in the control group. These figures are much lower than those in comparable series. The Singh index was not as sensitive an indicator of spinal osteoporosis as a direct measurement of vertebral bone density and could not be correlated with the incidence of hip fractures.

Traumatic hip luxation associated with ipsilateral and contralateral femoral fracture in a child.

In children, the association of traumatic luxation of the hip with homo- and heterolateral fracture of the upper extremity of both femurs, is extremely rare. In the case reported here, that association is present. Hip luxation can easily pass unrecognized. Orthopedic reduction is always recommended. Regarding the fracture of the upper portion of the femur in children under 10 years, when alignment of the fragments is not well achieved, surgical treatment should be considered. In this case, valgus osteotomy had to be performed in order to correct a post-traumatic coxa vara. After 4 1/2 years of follow up, the only sequel was a 1 cm leg-length discrepancy.

Middle third femoral fractures treated with medullary nailing or AO compression plates.

Fifty-eight medullary nailings and 46 internal fixations with AO plates were performed on fractures of the middle third of the femur. The complication rate was 21-2%, infections accounting for 7-7% and implant failures for another 7-7%. Critical descriptions of the failures are given, 6 of 8 implant failures being biomechanical. Follow-up results were excellent or satisfactory in 95% of cases in both groups. At follow-up after 3 1/2 years, there was no difference in results between the two methods of treatment.

Closed treatment of femoral fractures with the fluted Sampson intramedullary rod.

A technique of closed intramedullary rodding of femur fractures using a curved fluted Sampson rod under fluoroscopic control is presented. Seventy-nine patients have been treated by this technique over the past four years. In this series there have been no cases of nonunion. There was a 6.3 per cent infection rate. There were three nerve injuries. No leg length discrepancy greater than 1 inch was encountered. We believe that the technique has been successful and has answered the demands of our young trauma population. We remain enthusiastic about its use.

[Femoral fractures treated with intramedullary nailing by Küntscher's method. A review of results in 100 patients treated during a period of 10 years].

The records of 100 patients with 102 fractures of the femur treated with intramedullary nailing by Küntscher's method are reviewed. Eighty-eight of the patients were followed-up with interviews and clinical examination. Fifty-six of the patients had multiple traumata. Primary boney union was achieved within one year in 94 fractures (92%). At follow-up, the majority of the patients had no residual shortening of the affected extremity and no angulation at the fracture, and most of the patients had regained full movement of the knee and hip and good quadriceps function. In spite of this, 49% of the patients seen at follow-up had problems with their previous employment and/or performance in sports and daily activities. It is concluded, that some of the problems are probably due to the associated injuries and others are probably due to residual shortening of the affected extremity and restriction in knee movement.

Antibiotic prophylaxis in operations on trochanteric femoral fractures.

Short-term prophylaxis against infection using cephalothin and cephalexin was studied in 140 patients operated on for trochanteric fractures of the femur. The group given the drug during preparation for anesthesia, intraoperatively, and for two days postoperatively had an infection rate of 1.8 per cent (one patient), whereas the group without prophylaxis had a rate of 16.9 per cent (twelve patients). The two groups were similar with regard to factors that may have influenced the infection rate, for example, age, time required for surgery, and blood loss. Staphylococcus aureus was the most common infecting organism, but several patients had mixed infections with intestinal bacteria.

[Ender nailing of proximal femoral fractures in advanced age--experiences and results].

It is reported of 81 patients (average age: 86.1 years) with fractures of the proximal femur who have been treated with Ender-nails. The results of the preoperative state justify the immediate operation. Local complications were found in 29.6% out of the cases, mainly outcracks of the corticalis in 14.8%. The hospital letality was 19.8%. In 35 patients a follow-up examination was done after an average period of 20.2 months. Before operation about 75% of patients had a very good or good degree of mobility, in follow-up examination the rate was about 50%.

[Social medicine sequelae of femoral fractures near the hip in elderly patients].

On the basis of uni- and multivariant statistic analyses on 1700 old-age patients suffering from hip-joint near femur fractures, socio-medical initial and final parameters of treatment are shown the correlations between the quality of osteosynthesis, psycho-physical ability to walk at the time of discharge and subjective assessment of the personal living circumstances being pointed to. With the help of a long-term study covering a period of 13 years after the accident, it is established that the further posttraumatic life expectancy of old people decidedly depends on the development of their ability to walk after their discharge from the hospital.
