    Description / Table of Contents: Résumé Les auteurs décrivent une nouvelle prothèse fémorale modulaire associant une prothèse conventionnelle et un clou centro-médullaire. La prothèse est constituée d’une pièce céphalique et d’une partie diaphysaire fixées ensemble par un cône morse. Chaque pièce est modulaire selon les besoins en longueur et en diamètre. L’antéversion de la pièce céphalique est libre. Les pièces diaphysaires ont une courbure sagittale anatomique et sont creuses, permettant l’utilisation d’un guide centro-médullaire. Les pièces diaphysaires longues peuvent être verrouillées. Les pièces céphalique et diaphysaire sont en alliage de titane et la pièce diaphysaire a une surface grenaillée dans sa partie proximale. Le cône morse a été optimisé par l’adjonction d’une rainure qui a diminué l’usure par abrasion lors des tests de fatigue. Aucun démontage de la jonction intraprothétique et aucune fracture dé tige n’a été rencontrée lors de c es tests. La technique opératoire n’offre aucune particularité. Cent vingtquatre prothèses ont été implantées depuis 1990, principalement pour des fractures du col fémoral et des changements de prothèses totales de hanche. Les résultats cliniques sont en cours d’investigation. D’autres indications plus rares ont été choisies : pseudarthrose per-trochantérienne, fracture sur coxarthrose, chirurgie métastatique. Cette prothèse permet un ancrage diaphysaire stable dans les pertes de substance de l’extrémité supérieure du fémur, et autorise ainsi la repousse osseuse dans cette zone, spontanée ou après greffe osseuse, et la fixation proximale secondaire. L’optimisation du cône morse a permis de diminuer de façon considérable l’usure par abrasion. La modularité de la prothèse permet de s’adapter à toutes les morphologies et toutes les situations cliniques.
    Notes: Summary The development and clinical indications of a new modular femoral endoprosthesis consisting of a head and shaft component is discribed. Components are available in different lengths and diameters and therefore can be joined individually depending on the patients anatomy and surgery required. Both parts are joined by a unique optimized taper socket with a groove, avoiding fretting and corosion. Fatigue tests showed no loosening of the tapered connection and no prosthesis fracture. The advantage of this new modular prosthesis is diaphyseal stabilization, if necessairy by two distal interlocking screwes. Indications are revisions, pertrochanteric femoral and neoplastic fractures if cementless bridging of boney defects in the calcar region must be achieved. Further indications are femoral neck fraktures and coxarthrosis if stable diaphyseal fixation is required. The material and surface structure as well as the philosophie of the distal fixation are discussed.

    Posterior stabilization of C2 metastases by combination of atlantoaxial screw fixation and hook plate (1994)

    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).

    Description / Table of Contents: Zusammenfassung Weichteil- and Knochendefekte stellen den Unfallchirurgen am Unterschenkel vor große Probleme. Mit autochtonen Muskel- Bowie mikrovascularen Lappen läßt sich ein stabiler Weichteilmantel mit autologen Beckenknochen die Tibia wiederherstellen. 54 Weichteildefekte am Unterschenkel wurden 41mal mit Muskel- und 13mal mit mikrovascularen Lappen gedeckt. Zu Lappennekrosen bzw. Teilnekrosen kam es in l2 Fällen. Bei diesen waren Sekundärmaßnahmen zur Deckung and Heilung notwendig. Durch die Spongiosaplastik and kombinierte Weichteildeckung mit Muskulatur oder mikrovascularen Lappen IABt sich die Funktion eines beschädigten Unterschenkels wieder erlangen.
    Notes: Summary Many problems rise from soft tissue and bone defects in the lower leg. Soft tissue can be reconstructed by muscle or microvascular flaps, and bone defects can be restored with autogenous bone. Fifty-four soft tissue defects in the lower leg were treated in 41 cases with muscle flaps and 13 with a microvascular flap. In 12 cases, total or partial flap necrosis occurred. These cases required further treatment to obtain healing. Function of a damaged lower leg can be restored by combined therapy with local muscle or microvascular flaps and pelvic bone transplantation.

    Description / Table of Contents: Zusammenfassung Der postoperative Frühinfekt nach Osteosynthese gefährdet eine sichere, fristgerechte Ausheilung. Die sofortige chirurgische Revision des Infektherdes ist angezeigt. Implantate, die nicht sicher stabilisieren, werden entfernt. Implantate, die die Revascularisation des Infektfoyers behindern, werden ebenfalls entfernt. Die Restabilisierung erfolgt durch den Fixateur externe, so daß der gefährdete Knochenbezirk frei von Metallimplantaten bleibt. Der Fixateur externe sollte nicht länger als ca. 3 Monate belassen werden, bei Zeichen des knöchernen Durchbaus funktionelle Behandlung. Ansonsten ist eine Reosteosynthese mit Transplantation von Knochen notwendig.
    Notes: Summary Acute osteitis after osteosynthesis of closed or open fractures must be immediately surgically revised. Metal implants not stabilizing the fracture or interfering with the revascularization of the infected area must be removed. Restabilization should be done using external fixation, this is possible without using metal implants incorporated in the infected area. External fixation should be used for a period of at least 3 months. Thereafter, if possible, functional treatment should be used.
