    Description / Table of Contents: Summary An objective functional evaluation after acute repair of unilateral anterior cruciate ligament (ACL) rupture was performed in a homogeneous group of 37 patients at a mean of 44.4 months after trauma. A patient questionnaire, standardized clinical testing, instrumented laxity testing and concentric isokinetic muscle torque evaluation were included. Instrumented laxity testing proved to be closely correlated with the pivot shift test (r=0.54, p〈0.001) and the Lachman test (r=0.73, p〈0.001), but offered a far better resolution. The degree of anterior instability as measured could be shown to correlate negatively with the isokinetic flexor muscle torque (r=−0.61, p〈0.001) and the hamstring/quadriceps ratio (r=−0.44, p〈0.05). The intraindividual differences of instrumented laxity testing revealed that a significant degree of instability (〉2 mm) was present in 49% of the patients contrasting with the good result in the Lysholm score (mean=84.5 pts.) and a 74% rate of satisfied patients. Instrumented laxity testing makes a significant contribution to objective evaluation of functional results after ACL repair.
    Notes: Résumé Une évaluation fonctionnelle objective a été effectuée après réparation unilatérale de rupture du ligament croisé antéro-externe (LCAE) dans une série homogène de 37 patients, avec un recul moyen de 44,4 mois par rapport au traumatisme. Un questionnaire, un contrôle clinique standardisé, des tests instrumentaux de laxité ligamentaire ainsi qu'une évaluation du moment de torsion musculaire isokinétique concentrique furent utilisés. Le contrôle instrumental de la laxité ligamentaire peut être considéré comme très proche du test d'instabilité du pivot (r = 0,54, p 〈 0,001) et le signe de Lachman (r = 0,73, p 〈 0,001) mais est plus rapidement décisif. Le degré d'instabilité antérieure mesuré pourrait être considéré comme corrélé négativement avec le moment de torsion musculaire isokinétique concentrique (r = 0,61, p 〈 0,001) et le rapport ischio-jambiers/quadriceps (r = 0,44, p 〈 0,005). Les différences entre les sujets des tests instrumentaux de laxité ligamentaire révèlèrent qu'un degré significatif d'instabilité (〉 2 mm) existait chez 49 % des patients, ce qui contraste avec les bons résultats au score de Lysholm (moyenne : 84,5 points) et une proportion de 74 % de patients satisfaits. Ainsi le test instrumental de laxité ligamentaire apporte-t-il une contribution importante à l'évaluation fonctionnelle post-opératoire des ligamentoplasties du LCAE.

    Notes: Summary A new technique for the stabilization of metastatic cervical instability of the axis and/or neighboring vertebrae at lower levels is described. By a combination of the transarticular screw fixation C1/2 (Magerl) with the hook plate technique (Magerl) (or facultatively with a 1/3 tubular or 3.5 mm dynamic compression plate) from a posterior approach, the risks and stresses on the patient of a transoral or a combined extended technique are avoided, creating a proven biomechanically stable situation. The new technique is particularly helpful in those patients with a rapid progression of their malignant disease in whom local tumor growth is not expected to compress the spinal cord, and palliative stabilization of the unstable upper cervical spine can avoid neurological deficits or alleviate pain syndromes at a minimized morbidity due to surgery. The new technique has been successfully applied in a limited clinical series of four patients with metastasis of the cervical spine, resulting in substantial improvement of the general condition and cervical pain syndrome and stability of the assemblage during the observation period (4–9 months).

    Thoracoscopic repair of thoracic spine trauma (1995)

    Notes: Summary Modern concepts of treating thoracic and lumbar spinal trauma are based on posterior transpedicular fixation techniques which confer angular stability and instrument only a few levels of the spine. In addition, to prevent secondary losses in postoperative reduction of kyphotic deformities, transpedicular resection of torn dises, and inter-and intracorporeal bone grafting are included in the repair procedures for the entire damaged motion segment. However, due to the small size of the pedicles, a transpedicular approach to the injured vertebral body is not possible in the upper thoracic spine. Patients whose thoracic spine trauma is not serious enough to require ventral instrumentation through open thoracotomy, but who present with an unstable vertebral fracture, may profit from additional ventral bone grafting to stabilize the fracture. The present study examined the feasibility of thoracoscopic ventral bone grafting in seven patients with unstable fractures of the upper thoracic spine. For primary repair, we stabilized the fracture by using posterior transpedicular screw systems (rods or plates). Simultaneously, spongiosa was harvested from the posterior iliac crest and deepfrozen. Repair was completed a few days later via a ventral thoracoscopic approach. The main location of the ventral osseous defect was identified by intraoperative radiology. After mechanical removal of destroyed connective tissue and disc material, fusion was performed using the previously harvested spongiosa, which was placed into the intervertebral disc space and the anterior osseous defect. Our results show thoracoscopic bone grafting to be technically possible and associated with low morbidity, with a potential of yielding satisfactory long-term results.

    Description / Table of Contents: Summary From January 1997 to August 1998 all stabel and nonstabel trochanteric femoral fractures (n=72) were treated routinely by gamma nail using the correct operative technique. Patients showing additional osteoarthritis of the hip in radiographs hip replacement was performed by a cementless modular femoral hip prostheses from January 1996 to August 1998 (n=28). Follow up period was 6 to 18 months. Operation time and blood loss were higher using the prostheses. However complications and letality (〈5%) were not different during postoperativ course. In each group three operative technical complications occured. Using a modified Harris Hip Score (without range of motion, contractions) the score was decreased non significant comparing both groups first of all in unstabel fractures until follow up. In each group one revision (loosening of prostheses, excessive shortening of femoral neck) was necessary. Using the correct operative technique, the gamma nail prooved to be a save device with good outcome. Outcome using modular prostheses is comparable to gamma nail. Therefore the use of modular prostheses is justified in case of osteoarthrosis and in some cases of very unstable fracture.
    Notes: Zusammenfassung In der Zeit vom 1.1.1997 bis 1.8.1998 wurden alle stabilen und instabilen per- bis subtrochantären Femurfrakturen (n=72) routinemäßig durch einen Gammanagel (GN) unter Anwendung der korrekten Operationstechnik stabilisiert. Ausgenommen waren Patienten, die radiologisch eindeutige Koxarthrosezeichen hatten. In dieser Vergleichsgruppe (n=28) wurde der Gelenkersatz durch eine zementfreie, modulare Hüftprothese (MHP) durchgeführt und die Patienten im Zeitraum vom 1.1.96 bis 1.8.98 ebenfalls prospektiv erfaßt. Die Nachuntersuchung erfolgte nach 6–18 Monaten. Trotz längerer Operationszeit und höherem Blutverlust in der MHP Gruppe bestand kein Unterschied an Komplikationen und Letalität (〈5%) während des stationären Aufenthalts. In jeder Gruppe waren drei operationstechnische Komplikationen nachweisbar. Unter Verwendung eines modifizierten Harris-Hip-Scores (ohne Bewegungsumfang, Deformität) zeigten beide Gruppen eine nicht signifikant unterschiedliche Abnahme der Punktzahl vor allem bei den instabilen Frakturen zum Zeitpunkt der Nachuntersuchung. In jeder Gruppe mußte ein Patient (Sinterung im Frakturbereich, Prothesenlockerung) revidiert werden. Unter Anwendung der korrekten Operationstechnik ist der GN ein sicheres Implantat. Die MHP zeigt gleich gute Ergebnisse mit gleicher Letalität, so daß der Einsatz bei Koxarthrose und in ausgewählten Fällen auch bei hochgradig instabilen Frakturen gerechtfertigt ist.

    Description / Table of Contents: Abstract Posttraumatic osteitis is still the most important complication of bone surgery. In the last 30 years we have learned that antibiotics do not solve the problem. For 13 years Taurolin-Gel 4% has been used as a local bactericidal agent. Over 500 patients with acute or chronic osteitis have been treated. The overall results of the different studies show that in 86% infection free consolidation could be achieved.
    Notes: Résumé L'ostéite post-traumatique constitue une importante complication de la chirurgie orthopédique. Une expérience de 30 ans nous apprend que l'antibiothérapie seule est inefficace. Depuis 13 ans, nous utilisons le gel de taurolidine en tant qu'agent local bactéricide. Plus de 500 patients présentant une infection osseuse ont été traités. La revue des cas au dernier contrôle a montré un pourcentage de 86 % de guérisons de l'infection.

    Description / Table of Contents: Zusammenfassung Intraindividuell wurde an 10 Patienten nach Ersatz der infrarenalen Bauchaorta Dopamin I mit 3μg · kg−1 · min−1 und Dopamin II 6 μg · kg−1 min−1 mit Dobutamin I 4 μg · kg−1 · min−1 und Dobutamin II 8 μg · kg−1 · min−1 auf ihre unterschiedliche Beeinflußung der cardialen und renalen Parameter untersucht. Signifikante haemodynamische Unterschiede ergaben sich in der Senkung des rechten Vorhofdrucks und linksventriculären Füllungsdrucks unter Dobutamin II im Vergleich zu einer Steigerung bei Dopamin II. Die Urin- und Natriumausscheidung war in beiden Gruppen bei Dopamin signifikant höher. Beim chirurgischen Intensivpatient ohne kardiale Vorerkrankung genügt zur Kreislaufsteigerung Dopamin.
    Notes: Summary Following replacement of the infrarenal abdominal aortic segment, ten patients were given dopamine (Dop) and dobutamine (Dob) at two different dosages: Dop I (3 μg · kg−1 · min−1), Dop II (6 pμg · kg−1 · min−1), Dob I (4 μg · kgt−1 · min−1), and Dob II (8 μg · kg−1 · min−1). The changes in hemodynamic and renal parameters were studed in each individual patient. Significant differences were shown only in the reduction of right atrial pressure and left ventricular filling pressure during Dob. II application, compared to an increase which occurred with Dop. II. The output of urine and sodium was significantly higher in both groups after dopamine. In the surgical intensive care patient without cardiac disease, adequate circulation can be obtained with dopamine alone.
