RESUMEN
The performance of the external fixation regarding severe fractures of the distal radius was evaluated by means of a very detailed retrospective study. Between 1989 and 1994 74 Patients with 76 fractures of the distal radius with a mean age of 69 years for female and 39 years for male patients were treated with the external fixator. 37% were open fractures. Using the ASIF classification, 21% were type A-fractures, 8% were type B-fractures and 71% were type C-fractures. In 44 cases the external fixator was used primarily, in 32 cases secondarily after failed conservative treatment. Additional procedures were partially necessary (K-wires, screws, bone grafts etc.). 32 complications had to be noted, the lesion of the superficial branch of the radial nerve being the most common (16%). After a mean follow up of 36 months 60 patients with 61 fractures could be evaluated clinically and radiologically. With the Sarmiento score as well as the Castaing score, 84% could be classified as very good or good, 16% as fair, no poor results were recorded. From this study we conclude that the primary treatment of complex fractures of the distal radius can be performed with external fixation along with the additional procedures necessary (K-wires etc.). Because of the reliable elimination of pain caused by the fracture, it forms a preventive measure against reflex sympathic dystrophy.

According to the "sense of coherence" concept, those subjects who can give meaning to a traumatic event can comprehend what has happened and have a sense of manageability of the sequelae, are able to cope better with the traumatic event itself. In the present study, this concept was applied to traffic accident victims. Severely injured traffic accident victims were assessed a few days after the accident and at 6-month follow-up. At follow-up, patients filled in the 29-item version of the Sense of Coherence (SOC) self-rating scale. The results show that the SOC total score correlated negatively with the development of: (i) posttraumatic psychopathology; (ii) psychological disorders (i.e., posttraumatic stress disorder after the accident); and (iii) anxious cognitions. The personality trait of neuroticism correlated negatively and extraversion and frustration tolerance correlated positively with SOC total score. Previous hypotheses are supported by our findings.

Since transmission of HIV through allogenic bone grafts has been established, the concept of cryopreservation of allogenic bone had to be reconsidered. The strict guidelines of the scientific board of the Bundesärztekammer of 1990 are very labour-, time- and money-intensive. We have therefore moved to autoclaving allogenic cancellous bone. This is harvested from femoral heads during THR in slices of 2 to 3 mm, then cleaned under non-sterile conditions with a hard water jet followed by an ultrasonic bath for approx. 20 minutes. The slices are then double sealed individually and autoclaved at a temperature of 134 degrees C and a pressure of 2.5 atmospheres. Storage is in sealable containers at room temperature, so the material available at any time. Since the bone tissue has been freed of most organic matter and therefore lost its bone-specific antigenic structure, all that is left is the anorganic component with its inimitable architecture. This treatment results in a cancellous bone graft which is sterile, biocompatible and osteoconductive. Biologically it is inferior to autogenic and cryopreserved bone. Experimental and clinical studies show, however, that autoclaved cancellous bone can be a suitable substitute in well-selected indications. To elucidate the ultrastructural changes of the spongiosa and proteins induced by autoclaving further investigations are necessary. For example, the specific proteins involved need to be determined.

In a prospective clinical study the intraarticular pressure of 55 patients with intracapsular femoral neck fractures was measured intraoperatively with the hip in different positions. Intraarticular hemarthrosis was quantified by a preoperative sonography examination. In 75% of the patients, increased intraarticular pressure caused by the hemarthrosis was found. The spontaneous median pressure increased significantly from 22 mm Hg with extension (28 mm Hg) and internal rotation of the hip joint (56 mm Hg). The lowest pressure was found in 70 degrees flexion (15 mm Hg). The median pressures increased within the first 24 hours after injury from 26 mm Hg in the first 6 hours to 46 mm Hg from 7 to 24 hours. Even in the first and second weeks after trauma, increased median pressures were detected (8.5 mm Hg and 13 mm Hg, respectively). No significant difference was found between undisplaced and displaced fracture types. Because increased joint pressure in other studies correlates with reduced perfusion of the femoral head, it can be deduced that reduction maneuvers without capsulotomy can compromise the circulation of the femoral head. Capsulotomy and osteosynthesis of the femoral neck at the earliest time possible is the best prophylaxis of tamponade. If the osteosynthesis is delayed, a preoperative sonography after admission and a control sonogram after 6 hours is recommended. In the event of relevant hemarthrosis, immediate therapeutic drainage is suggested for patients who will receive joint conserving osteosynthesis.

In the past, biomechanical investigations on the dorsal pelvic ring have generally been performed on a small number of cadaveric pelves in various non-standardized procedures. Significant differences in stability between different internal fixation methods of unstable pelvic ring fractures were not found. The experimental design presented here was based as closely as possible on the physiological loading of the pelvis in one-leg stance. This method made it possible to carry out standardized, reproducible tests on different osteosytheses of the sacroiliac joint. Furthermore, the suitability of artificial bones for such investigations can be assessed on the basis of a larger number of similar experiments on artificial and human pelves and the number of human pelves required for such studies could be reduced.

Road traffic accidents often cause serious physical and psychological sequelae. Specialists of various medical faculties are involved in the treatment of accident victims. Little is known about the factors which might predict psychiatric disorders, e.g. Posttraumatic Stress Disorder (PTSD) after accidents and how psychological problems influence physical treatment. In a prospective study 179 unselected, consecutively admitted road traffic accident victims were assessed a few days after the accident for psychiatric diagnoses, severity of injury and psychopathology. All were inpatients and had to be treated for bone fractures. At 6-months follow-up assessment 152 (85%) of the patients were interviewed again. Of the patients, 18.4% fulfilled the criteria for Posttraumatic Stress Disorder (DSM-III-R) within 6 months after the accident. Patients who developed PTSD were injured more severely and showed more symptoms of anxiety, depression and PTSD a few days after the accident than patients with no psychiatric diagnosis. Patients with PTSD stayed significantly longer in the hospital than the other patients. Multiple regression analysis revealed that the length of hospitalization was due mainly to a diversity of factors such as severity of injury, severity of accident, premorbid personality and psychopathology. Posttraumatic stress disorder is common after road traffic accidents. Patients with PTSD at follow-up can be identified by findings from early assessment. Untreated psychological sequelae such as PTSD cause longer hospitalization and therefore more costs than in non-PTSD patients.

Almost 50% of acetabular fractures occur in polytraumatized patients; in over 80% additional injuries are found. The surgical goal is anatomical restoration of the acetabulum and stable fixation, in order to avoid postoperative external fixation. Careful clinical and radiological evaluation is essential to successful surgery. Standard radiological investigations include an anteroposterior view of the pelvis, a "spot" radiograph of the affected hip as well as obturator and iliac oblique views. The latter arc is especially helpful in assessing the central segment of the acetabulum ("dome fragment"). The documentation of any primarily traumatic sciatic nerve lesion is very important, and the quality of reduction depends greatly on the timing of surgery. The operation should be performed as early as possible after the surgical procedure has been carefully planned. A 3-D CT scan provides good information in choosing the surgical approach for complex fractures. In most cases, adequate reduction cannot be accomplished without appropriate aids. For internal fixation, both curved ASIF plates and straight plates are used. The operation demands a high degree of experience. Postoperative complications include iatrogenic nerve palsy, insufficient reduction, incorrectly placed implants, unstable fixation, redislocation, etc. With scrupulous aseptic conditions, the postoperative wound infection rate is low. Ectopic bone formation can occur after extensive surgical approaches and may, depending on size (Brooker III and IV), impair the range of motion of the hip. Indomethacin given perioperatively is always indicated. Postoperative radiation treatment should as a rule be viewed critically.

The long-term functional results of acetabular fractures are assessed in terms of the corresponding criteria of Merle-D'Aubigné and Postel (pain, mobility, walking). Other essential criteria include the quality of reduction and the radiological appearance. The age of the patient, the type of fracture and above all, the interval between the accident and the surgical treatment or reduction of the fracture must be counted among the decisive factors which influence the late effects of this injury. Whether or not reduction can correctly center the femoral head in the socket is of paramount importance, but postoperative infection or the development of a hematoma may also critically affect outcome. In addition to a report on the long-term results achieved at the Trauma Department of the University Hospital of Freiburg, Germany, the literature on the late complications of acetabular fracture is also reviewed.

It has been observed that after reduction of an unstable vertebral fracture, treated either conservatively or operatively, the encroachment of the spinal canal remaining after reduction can decrease considerably with time. A series of 31 cases, each with a set of CT scans taken preoperatively, immediately after surgery and after implant removal respectively, was assessed using computer-aided planimetry. The mean initial narrowing of the spinal canal was 44.6%. Through surgery this was decreased by 20.4%, leaving a remaining deficit of 24.2%. After implant removal, 15 months after trauma and surgery, the area of the spinal canal increased a further 17.4%, leaving a remaining deficit of only 6.8%. Comparing the values of the spinal canal for T12-L5 directly after surgery and after implant removal, an almost identical degree of restoration for each level can be seen. This additional and gradual restoration of the spinal canal is termed remodeling. This study demonstrates that a residual postoperative narrowing of the spinal canal of up to 25% can be ignored, provided there is no initial neurologic damage.

PURPOSE: In an experimental study, the correlation between the trabecular bone density of the different regions of the proximal femur and the fracture load in the setting of femoral neck fractures was examined. METHODS: The bone mineral density of 41 random proximal human femora was estimated by single-energy quantitative CT (SE-QCT). The trabecular bone density was measured at the greatest possible extracortical volume at midcapital, midneck and intertrochanteric level and in the 1 cm3 volumes of the centres of these regions in a standardised 10 mm thick slice in the middle of the femoral neck axis (in mg/ml Ca-hydroxyl apatite). The proximal femora were then isolated and mounted on a compression/bending device under two-legged stand conditions and loaded up to the point when a femoral neck fracture occurred. RESULTS: Statistical analysis revealed a linear correlation between the trabecular bone density and the fracture load for the greater regions, with the highest value in the maximal area of the head (coefficient factor r = 0.76). CONCLUSION: According to our data, the measurement of the trabecular bone by SE-QCT at the femoral head is a more confident adjunct than the neck or trochanteric area to predict a femoral neck fracture.

Skeletal scintigraphy is the most frequently utilized nuclear medicine imaging procedure in traumatology. Concerning any skeletal abnormality associated with changes in local perfusion, exudation and metabolism, it is a sensitive functional imaging procedure to detect bony disease. However, because of the varying causes of bony disease, it is characterized by a low specificity. Further, specificity may be enhanced, when patient history, clinical and lab results as well as results obtained from other diagnostic imaging procedures are combined with the result of skeletal scintigraphy. On the other hand, it is known that metabolic abnormalities of the skeleton depicted by radionuclide imaging occur much earlier than structural changes visible on X-ray imaging. Beside skeletal scintigraphy, antigranulocyte antibody or labelled leucocyte imaging may greatly assist in the detection of inflammation or infection following joint replacement surgery, respectively. Ultimatively, a combination of clinical, lab and imaging results including radionuclide imaging may represent the best approach to answer some questions asked by surgical traumatologists.

RESUMEN
UNLABELLED: Perfusion and Vitality of the Femoral Head after Medial Neck Fracture and Osteosynthesis. AIMS: to analyse with regard to necrosis the perfusion and vitality of the femoral head after medial neck fracture and repair by placement of a dynamic hip screw. PATIENTS AND METHODS: Twenty-one patients were examined by scintigraphy immediately following operation as well as at 3 and 6 months postoperative for evaluation of dysfunctions of perfusion and mineralization. RESULTS: Complete perfusion and mineralization defects with a tendency for revascularization at 3 months will be normal at 6 months. Persisting dysfunctions at 3 and 6 months will progress to femoral head necrosis irrespective of the fracture staging. CONCLUSIONS: Three-phase skeletal scintigraphy is a highly sensitive, non-invasive method for evaluating perfusion and revascularization of the femoral head after femoral neck fracture and repair by means of a dynamic hip screw. When perfusion of the femoral head is observed one week after the trauma, femoral head necrosis will not arise. Immobilization is necessary after partial or complete perfusion and mineralization dysfunctions until the scintigraphic findings return to normal. The present results may serve as a recommendation for loading after fracture repair with a dynamic hip screw.

Aseptic pseudarthrosis may occur after all kinds of traumatology treatment. Following conservative treatment, incomplete immobilisation or an unattached bone fragment can be causal. After plate osteosynthesis the biomechanical principles are not efficient or the circulatory damage delays healing. There are two broad types of pseudarthrosis: vascular and nonvascular. The extent of vascularisation can be demonstrated by bone scintigraphy as well as X-ray. The treatment of vascular nonunions is very common. Mechanical stability is required, therefore a new osteosynthesis is desirable. Osteoporosis caused by inactivity and dislocation increases the rate of complications. Much more difficult problems are encountered in treatment of unreactive and avital pseudarthrosis, particularly in cases with a defect of bone substance. These defects can be treated with a segment transfer and a fibula-to-tibia operation. Extracorporal lithotripsy has been established as a new method in treatment of active and vascular nonunions. Former osteosynthesis is not a contraindication. Stability and immobilisation are necessary. Treatment in the low-frequency magnetic field shows no effect. Correct biomechanical and biological osteosynthesis with proper attention paid to location, quality of bone and asepsis can avoid the development of a pseudarthrosis.

In 106 cases of unstable vertebral fractures treated with the ASIF internal fixator, the degree of restoration of the spinal canal could be studied in detail. Computer-aided planimetry was used to measure the area of the spinal canal. Three series could be studied, where the postoperative CT scans had been performed at different times. The first series of 58 cases had the CT scans taken immediately after surgery; the initial mean traumatic narrowing of the spinal canal had been 42.8%, but after surgery it was only 25.2%. The second series consisted of 74 CT scans performed after implant removal. At this time, a residual defect of only 3.7% was observed. In a third series 31 cases could be analysed where CT scans obtained both directly after surgery and after implant removal were available. This confirmed the first two series insofar as it demonstrated the existence of a further mechanism, i.e. remodeling, that served to increase the degree of restoration of the spinal canal. This biological-functional process operates to approximately the same degree at each fracture level, demonstrated by the almost parallel course of the graph showing reduction plus internal fixation and remodeling. In summary, the remaining deficit of 25% after surgery is restored almost to normal through remodeling and can be neglected, provided there is no neurologic damage.

Today an increasing number of automobiles are being equipped with additional passive safety devices: driver and passenger airbags. To examine the efficiency of the airbag in real road traffic accidents, a collective study was conducted from 181 traumatology centres throughout Germany. The inquiry was answered by 81 per cent of the medical centres contacted. From the evaluation of 122 accident victims in 1993 who were protected with an airbag the following was concluded. The patients treated in surgical and in traumatological departments suffered predominantly superficial injuries of the head, cervical vertebra and thorax. Some of these chiefly superficial wounds, such as abrasions and bruises, were initiated by contact with the airbag. It is remarkable that 72.1 per cent of the airbag-protected patients suffered a maximum of MAIS 2. What is also notable is the continuing high number of patients suffering from severe injuries (AIS 3+) of the lower extremities.

Recurrent haemarthros is described as consequence of cruciate ligament repair. The main cause of haemarthros is described after unisometric fixation of the ligaments which leads to the rupture of the synovia membrane. This is a case report of a young man, who suffered from recurrent haemarthros for several years although he has intensively examined by radiological and arthroscopical means. It was falsely presumed to be a muscular arthrophy. The cause, however, was found in a wire suture, which was used to fix the anterior cruciate ligament in the femoral bone. This suture was laying under the synovia within the ligament and there fore could be seen and taken away arthroscopically only after total synovialectomy.

In the treatment of fractures of the calcaneus, the particularly intricate local anatomy, complicated fracture forms and associated soft tissue damage often prejudice operative, anatomical reconstruction. We propose a simplified classification that is based on the Regazzoni classification of 1993 and has six grades of severity. It can be helpful in the selection of operative treatment and, above all, make it possible to recognize whether operative reconstruction is possible and appropriate. When operative reconstruction is indicated we find the secondary operation important; it is also important to diagnose and treat compartment syndrome if present and otherwise to take steps to prevent it. In the first phase, in special cases we use an external fixator without reconstruction of the full length. The operative technique is largely standardized as as the fixator is placed only temporarily. Correct positioning allows easy correction of shortening or varus deformation, and joint surface reconstruction is also feasible. Autologous bone grafting is possible. The definitive fixation is achieved with internal plate stabilization by a lateral approach and removal of the fixator. Contraindications for this procedure are burst fractures with total destruction of the joint surfaces and cartilage. Out of 54 fractures we used the fixator to aid reduction in 45. In 71% of these we had very good and good results according to the Merle d'Aubigné scoring system.
