    Notes: Abstract Cushing´s syndrome is frequently associated with osteoporosis. Therefore, the incidence of osteoporotic spine fractures is significant. They are a rare cause of paraplegic syndromes. Additionally, epidural lipomatosis may occur in those patients. The combination of both fracture and lipomatosis may cause neurological deficit. A case of a young patient suffering from drug-induced Cushing’s syndrome is reported. She developed progressive paraplegia. Radiographs demonstrated kyphosis of the thoracic spine from T7 to T9 and pathologic fractures. Urgent operation was planned to stabilize and decompress the spinal cord in the area of the kyphosis. Fortunately, magnetic resonance imaging (MRI) was conducted first. It confirmed pathologic fractures of T7–9 but also showed massive epidural fat extending from the level of T1 to T9. As suspected, laminectomy alone in the area of the fracture proved to be insufficient, as shown by myelography during operation. For treatment of paraplegia in this case of symptomatic epidural lipomatosis, an expanded laminectomy was necessary to remove all the epidural fat. Having undergone this procedure, the patient is now recovering from paraplegia. Our experience suggests that care should be taken before operative treatment of patients with pathological fractures in combination with Cushing’s syndrome. In addition to vertebral fractures, epidural lipomatosis has to be taken into consideration. Those patients with neurological deficits have to be treated by an extensive laminectomy.

    Description / Table of Contents: Summary Anterior decompression in spinal metastases of the corporal type with impending (n=5) or present (n=36) neurological complications was performed in 41 patients. For reconstruction, a titanium cylinder was inserted after spondylectomy and augmented with an anterior plate. The titanium implant can easily be adjusted to the length needed without necessitating expensive additional equipment. Outside the patient the implant is filled with polymethylmetacrylate, facilitating plate transfixation for rotational locking. There was a 30-day mortality of 9.7%. Pain relief was apparent in 38 of 41 patients (92.7%), and motor improvement was manifest in 31 of 35 cases (88.6%). Six patients did not present with any neurological symptoms pre- or postoperatively. Neurological deterioration was registered in only 1 case (2.4%). Surgical efficacy was maintained until the death of the patients. Though tumor recurrence at a different spinal level led to consecutive surgery in 5 patients, no implant dislocation occurred during the observation period (maximum 44 months), characterizing the procedure as a mechanically reliable and safe technique.
    Notes: Résumé La décompression antérieure a été réalisée chez 41 patients porteurs de métastases du corps vertébral. Les complications neurologiques étaient patentes chez 36 patients et latentes chez 5 d'entre eux. On a utilisé pour la reconstruction un cylindre de titane, mis en place après la corporectomie et renforcé par une plaque antérieure. L'implant en titane peut être facilement adapté à la longueur nécessaire sans nécessiter de matériel supplémentaire et onéreux. L'implant est rempli de PMMA avant sa mise en place, ce qui facilite la transfixation nécessaire au verrouillage de la rotation. La mortalité à 30 jours est de 9.7%. La douleur a disparu dans 38 cas sur 41 (92.7%), l'amélioration motrice a été manifeste dans 31 cas sur 35 (88.6%), 6 patients ne présentaient aucun symptôme neurologique ni avant ni après l'opération. Une dégradation neurologique n'a été relevée que dans 1 cas (2.4%). L'efficacité du geste chirurgical a été maintenue jusqu'au décès des patients. Bien que la récidive tumorale à un autre niveau rachidien ait conduit à une chirurgie itérative chez 5 patients, aucun déplacement d'implant n'est survenu durant la période d'observation (recul maximum 44 mois), cela témoignant du caractère mécaniquement faible et sûr du procédé utilisé.

    Description / Table of Contents: Abstract There is an increasing number of patients with bone defects of the femur requiring primary or revision arthroplasty of the hip. Especially problematic in this respect are trochanteric fractures, periprosthetic fractures and aseptic loosening. We report about certain technical aspects, the postoperative course as well as clinical and radiological results after implantation of a modular hip prosthesis for these indications. The modular hip prosthesis consists of a separate head and shaft component with a stem similar to a femoral nail. One hundred and nine patients were prospectively recorded. Hospital mortality was 4.2% and as major surgical complications there were 6 femoral fractures which occurred intraoperatively. Follow-up (mean 13,2 months) could be completed for 48 patients (25 patients had already died). Two patients showed aseptic loosening of modular hip prosthesis and revision with a cemented prosthesis was necessary. In 2 patients with a condition following a periprosthetic fracture radiological signs of loosening could be detected. Quality of life assessed by a modified Harris Hip Score was comparable to the situation prior the fracture or even better in the group following the implantation of modular hip prosthesis because of aseptic loosening. Depending on the fact that 2 individual components, each of which coming in different sizes, can be assembled, the device shows a high degree of variability for different indications. Radiological and clinical results are good, however, follow-up time is too short for final evaluation. Periprosthetic fractures have to be treated more frequently by additional bone grafting in order to improve osseointegration of modular hip prosthesis.
    Notes: Zusammenfassung Die Anzahl an Patienten mit pertrochantären und periprothetischen Frakturen sowie mit aseptischer Prothesenlockerung nimmit kontinuierlich zu. Diese Patienten haben häufig eine Knochendefektsituation des proximalen Femurs. Wir berichten über die operativen, klinischen und radiologischen Ergebnisse bei diesen Indikationen nach Implantation einer modularen Huftprothese, die sich aus einem Prothesenteil und einem Schaft ähnlich eines Marknagels zusammensetzt. 109 Patienten werden prospektiv erfaßt. Die Klinikletalität lag bei 4,2%. Als häufigste intr-aoperative Komplikation traten sechs Femurfrakturen auf. 48 Patienten konnten in einem mittleren Zeitraum von 13,2 Monaten nachuntersucht werden, 25 Patienten waren bereits verstorben. Bei zwei Patienten mußte die modulare Hüftprothese wegen Lockerung gewechselt werden, zwei weitere zeigten radiologische Lockerungszeichen nach Versorgung einer periprothetischen Fraktur. Die Lebensqualität der Patienten, gemessen an einem modifizierten Harris-Score, war vergleichbar zum Zeitpunkt vor der Fraktur oder hat sich bei Wechseloperationen deutlich gebessert. Lockerungen der Prothesenverbindung traten nicht auf. Die modulare Hüftprothese bietet eine hohe Variationsmöglichkeit in der Zusammensetzung and ist deshalb bei vielen Indikationen anwendbar. Unter Einschränkung der kurzen Nachbeobachtungszeit sind die radiologischen und klinischen Ergebnisse gut, wobei in Zukunft bei periprothetischen Frakturen die Primärstabilität der modularen Hüftprothese durch Knochentransplantate ergänzt werden sollte.

    Notes: Abstract Trochanteric femoral fractures are frequently associated with severe osteoporosis in elderly patients. The failure of devices intended to repair trochanteric fractures, such as the gamma locking nail (GLN), might be related to reduced bone desity. Osteoporosis may also influence pain and walking ability because of low stability in the fracture area. In 74 patients (mean age 76 ± 16.5 years), the stability and clinical outcome following treatment with GLN were prospectively evaluated and recorded after 9 (n = 43) and 24 months (n = 34). Vertebral bone mineral density (BMD) was measured via quantitative computed tomography (QCT) at time of operation. Mechanical failure of GLN was recorded by radiographs of the hip. Assessment of outcome included the Harris Hip Score. Regression analysis was done to show the influence of age and BMD on clinical outcome. 9 months after treatment, complete fracture healing without dislocation of the lag screw of the GLN was observed even in patients with low BMD (〈 55 mg/cm3 trabecular BMD). Clinical outcome assessed by the Harris Hip Score was independent of BMD at both follow-ups. At the first follow-up, outcome depended on the patient's age, with younger patients (〈 70 years) showing better results than elderly patients. The stability of fracture also seemed to influence the outcome. Our results indicate that stabilization of unstable osteoporotic fractures with GLN is associated with few complications and can be accomplished with identical clinical and radiologic results seen in patients with high BMD. The critical factor influencing outcome is patient's age, stability of fracture and not BMD.
