    Description / Table of Contents: Abstract During 1985 and 1993, 7,410 persons were injured in traffic accidents in the area of Hanover. Of these, 306 (4.1%) sustained a pelvic girdle injury. In 139 cases (45%), the pelvic girdle injuries were further classified (Pennal and Tile) and a technical reconstruction of the accident situation was performed. 52% were type A, 27% type B and 21% type C injuries. Some 47% of the casualties were vehicle occupants, 31% pedestrians, 12% motorcyclists and 10% cyclists. In restrained vehicle occupants pelvic girdle injuries occurred mostly in accidents with a delta-v of more than 30 km/h, whereas in unrestrained vehicle occupants, pedestrians and cyclists they also occurred with lower delta-v or collision speed. The percentage of type B and C injuries increased with higher velocities. In addition to further improvements in passive safety, lower collision speed or delta-v is necessary to reduce or prevent pelvic girdle injuries. The reconstruction of pelvic girdle injury mechanism in traffic accidents is possible, when both technical and medical parameters are considered.
    Notes: Zusammenfassung Zwischen 1985 und 1993 wurden 7.410 Verkehrsunfallverletzte im Großraum Hannover erfaßt; 306 (4,1%) erlitten eine Beckenringverletzung mit einem AIS〉2. In 139 (45%) Fällen erfolgte die Klassifikation der Beckenringverletzung nach Pennal und Tile und eine vollständige technische Rekonstruktion; 52% waren danach Typ-A-, 27% Typ-B- und 21% Typ-C-Verletzungen. Bei den Verletzten handelte es sich um 46% PKW-Insassen, 31% Fußgänger, 12% Motorradfahrer, 10% Fahrradfahrer und 1% LKW-Insassen. Die Beckenringverletzungen traten bei gurtgeschützten Fahrzeuginsassen fast ausschließlich bei einem Δ-v von über 30 km/h auf, dagegen bei ungeschützten Verkehrsteilnehmern (Fußgänger und Radfahrer) und bei nicht gurtgeschützten Fahrzeuginsassen auch schon bei Anprallgeschwindigkeiten bzw. Δ-v von 10–20 km/h. Bei höheren Geschwindigkeiten stieg der Anteil der B- und C-Verletzungen. Neben weiteren Verbesserungen der passiven Sicherheit ist zur Verminderung oder Vermeidung von Beckenringverletzungen eine Verringerung der “Unfallgeschwindigkeit” nötig. Unter Berücksichtigung aller technischen und klinischen Parameter wird eine Rekonstruktion des tatsächlichen Unfallmechanismus von Beckenringverletzungen ermöglicht.

    Whiplash-type neck distortion in restrained car drivers: frequency, causes and long-term results (2000)

    Notes: Abstract An analysis was made of 1176 whiplash-type neck distortions taken from a total of 3838 restrained car driver incident reports. The percentage of whiplash-type neck distortion among injured drivers increased from less than 10% in 1985 to over 30% in 1997. Most occurred in head-on crashes or crashes with multiple collisions; only 15% occurred in rear-end collisions. More than 1,000 questionnaires were sent to the injured to find out about the duration and type of complaints caused by their cervical spine injury. Although only 138 (12%) returned the questionnaire, which may not be a representative sample, a further analysis was carried out. Of the 138, 121 (88%) indicated that they had suffered or were still suffering from their symptoms. The percentages of the various complaints were as follows: pain (74%), tension (6%) and stiffness (5%) in the head (27%), neck (55%) and shoulder (8%). The duration of the complaints was longest after multiple collisions and when the onset of complaints was longer than 24 h after trauma. Women and elderly persons predominated slightly in the group with longer duration of complaints. A correlation between the severity of the accompanying injuries and duration of complaints was found. Lack of adequate follow-up for patients with less severe injuries posed considerable difficulties for this retrospective study. In order to better evaluate this problem, prospective studies are necessary, with documentation including diagnosis, treatments, complaint duration and type.

    Description / Table of Contents: Zusammenfassung Im Zeitraum von 4/84–2/87 wurden in der Unfallchirurgischen Klinik der Medizinischen Hochschule Hannover insgesamt 86 zementfreie Revisions-Alloarthroplastiken mit dem PCA Hüftsystem (davon 12 mit Revisionsschaft) durchgeführt. Neben allogener Spongiosaplastik in allen Fällen wurde an 33 Acetabula zusätzlich ein grosser, allogener cortico-spongiöser Aufbau, an 6 Femura eine partielle oder totale Köcherrekonstruktion mit allogenen Spongiosascheiben durchgeführt. Bis auf 2 Lockerungen der acetabularen (n = 2) und der femoralen Komponente (n = 2) heilten alle Transplantate zusammen mit der zementfreien Prothese nach 3–12monatiger Entlastung stabil ein.
    Notes: Summary Between April 1984 and February 1987, 86 cementless revision alloarthroplasties with a PCA hip system were implanted at the trauma center of Hannover Medical School. In 12 cases, the PCA long stem was used. Allogenous cancellous bone grafts were used in all cases; 33 large acetabular defects were grafted with additional allogenous bone blocks. Six defects of the proximal femur were partially or totally reconstructed. During our 3-year follow-up, 2 acetabular and 2 femoral components loosened; the rest showed bony consolidation after 3 to 12 months of partial weight-bearing.
