    Description / Table of Contents: Résumé Nous avons observé un cas de kyste synovial intraosseux de la malléole externe. La lésion était associée à un kyste synovial pré-malléolaire. Il existait une communication entre l'articulation tibiotarsienne, le kyste intra-osseux et le kyste synovial. Les radiographies montraient une image kystique entourée d'une bordure scléreuse, ce qui semble indiquer que la lésion était peu ou pas évolutive. Ce cas est présenté avec une revue de la littérature.
    Notes: Summary We report a case of an intraosseous ganglion of the lateral malleolus of the ankle. The lesion was accompanied by a cystic bursa overlying the lateral malleolus. There were connections between the ankle joint, the intraosseous ganglion, and the overlying cyst. Radiographs of the lesion showed the cystic defect in the lateral malleolus surrounded by a sclerotic rim, suggesting that the lesion had progressed very slowly.

    Description / Table of Contents: Résumé Nous avons conduit une étude rétrospective de 75 malades porteurs d'un kyste solitaire des os afin de déterminer quels sont les types de kystes comportant un risque de fracture et si cette fracture peut accélérer la guérison du kyste. Soixante-quinze patients avec 52 fractures pathologiques ont été revus. Les lésions siègeaient en majorité au niveau de la métaphyse des os longs. Elles étaient localisées essentiellement à l'extrémité proximale de l'humérus et dans la partie supérieure du fémur. La surface occupée par le kyste dans le plan horizontal dépassait 85% sur les radiographies de face et de profil chez tous les patients présentant une fracture pathologique. Dans la plupart des cas l'évolution se fit vers la récidive et même vers l'extension du kyste originel, sans accélération du processus de guérison.
    Notes: Summary We carried out a retrospective review of 75 children with unicameral bone cysts, who had sustained 52 pathological fractures, to determine which cysts were likely to be at risk and whether healing was accelerated after a fracture. Most lesions were in the metaphysis of a tubular bone, the commonest sites being the the upper part of the humerus and femur. The percentage of bone occupied by the cyst in the transverse plane was more than 85% in both anteroposterior and lateral radiographs in every case of pathological fracture. In most cases, the cyst recurred and sometimes became large without any acceleration of healing.

    Description / Table of Contents: Résumé Deux cents quatorze patients, porteurs de 270 prothèses de hanche non cimentées, ont été suivis de deux à huit ans. Les prothèses PCA, AML et HGP (Harris-Galante) ont été utilisées indifféremment. Dans l'ensemble les résultats cliniques de ces trois prothèses sont identiques. Cinq ans après l'opération la cotation de Harris était en moyenne de 93 pour l'AML, de 93 pour la PCA et de 91 pour l'HGP. Quatre prothèses PCA présentaient un descellement radiologique aseptique, dont un a été repris en raison de l'usure du polyéthylène. Aucun descellement n'a été observé dans les prothèses AML et HGP. Les douleurs de cuisse, habituellement légères, sont survenues dans 17% des prothèses AML, dans 23% des prothèses PCA et dans 19% des prothèses HGP. Cinq ans après l'opération les modifications radiologiques, telles que migration, remodelage du calcar, liserés, sont identiques pour ces trois prothèses. Cependant la repousse osseuse radiologique paraît plus marquée au niveau de la tige fémorale des prothèses AML.
    Notes: Summary Two hundred and fourteen patients who had 270 cementless hip prostheses were followed for 2 to 8 years. PCA (Porous-Coated Monatomic), AML (Monatomic Medullary Locking) and HGP (Harris-Galante-Porous) femoral stems and acetabular cups were used without any preference for the prostheses. The overall clinical results were similar for the three prostheses with average Harris hip scores of 93, 93 and 91 respectively. Four PCA prostheses had radiological aseptic loosening and one was revised because of polyethylene wear. There was no loosening in the AML and HGP prostheses. Pain in the thigh, usually slight, occurred in 17% of AML, 21% of PCA and 19% of HGP prostheses. Five years after operation, radiological changes such as migration, calcar remodelling and radiolucent lines were the same for the 3 prostheses, but bony ingrowth was greater with the AML femoral stems.

    The effect of chondroitinase ABC on rabbit intervertebral disc (1995)

    Description / Table of Contents: Résumé La chymopapaïne et la collagénase sont des agents chémonucléolytiques connus dans le traitement des hernies discales. Cependant il y a souvent des problèmes sérieux avec ces enzymes, comme une neurotoxicité sévère ou une anaphylaxie qui peut être fatale. La chondroitinase ABC qui est un produit métabolique du Proteus vulgaris a une action particulière sur le protéoglycan du nucleus pulposus mais n'agit que rarement sur le tissue nerveux. Soixant-dix disques lombaires de lapins ont été examinés radiologiquement et histologiquement après une injection de chondroitinase ABC, à la dose de 40 U/ml par disque et comparés avec un groupe injecté par un tampon et avec un autre groupe de contrôle non injecté. Il existait un rétrécissement considérable de l'espace discal dans le groupe injecté par la chondroitinase ABC, qui était vérifié par la radiographie et l'histologie (p〈0.01). On observait une zone de disparition du safranion 0 au niveau ventral de l'annulus fibrosus, adjacent au nucleus pulposus, dans tous les disques traités, ce qui indiquait une perte de protéoglycan. En microscopie électronique on notait un collapsus des chondrocytes et des cellules notochordales. Toutes ces constatations prouvent que la chondroitinase ABC peut représenter un nouvel agent chémonucléolytique en diminuant le volume du disque et donc en décomprimant la moelle ou les racines nerveuses. Tous les effets histologiques de la chondroitinase ABC sont limités au tissu discal intervertébral. La chondroitinase ABC mérite d'être étudiée en tant qu'alternative pour la chémonucléolyse.
    Notes: Summary Seventy-eight rabbit lumbar discs were evaluated by radiographs and histology after the injection of chondroitinase ABC (40 U/ml for each disc) and compared with injection with phosphate buffer, and also with a control group who were not injected. There was considerable narrowing of the disc space after chondroitinase ABC injection. Safranin-0 depletion was present in the anterior part of the annulus fibrosus near to the nucleus pulposus in all the treated discs, indicating loss of proteoglycan. Electron microscopy showed collapse of the chondrocytes and notochordal cells. These findings suggest that chondroitinase ABC may be another chemonucleolytic agent which decreases disc volume and consequently decompresses the spinal cord or nerve roots; its effects were confined to the tissues within the intervertebral disc.

    Aesthetic problems of eye protrusion in Orientals (1999)

    Notes: Abstract  The typical characteristics of Oriental faces are less prominent supraorbital ridges, a flat and broad nose, and thick, bulky upper eyelids. These characteristics make the eye appear protruded even when they are within the normal range or on the borderline of the exophthalmometric data. Prior to correction of the protruding eye, the patient’s medical and psychological status are investigated. The volume of the bony orbit is estimated using 3-D CT scan data and exophthalmometry before and after the operation. The surgical correction is planned to decompress the orbital contents with preservation of the visual axis. The lateral orbital wall is expanded without change of facial width. The medial wall and orbital floor are outfractured with preservation of continuity of the maxillary and ethmoid bone and sinus mucosa to prevent herniation of the orbital contents and disturbance of extraocular muscle dysfunction. Removal of the retrobulbar fat is mainly from the upper half of the orbit. In the past three years, orbital decompression has been performed in eight patients (12 eyes) for aesthetic reasons. The exophthalmometric data ranged from 17.5 mm to 19.5 mm, with an average of 18.3 mm before operation, this changed 2.0 to 7.0 mm with an average of 3.54 mm after operation. The postoperative complications were two cases of subconjunctival hemorrhage and one case of temporary diplopia. After follow-up of 14 months (4–38 months), there were no cosmetic or functional problems.

    Notes: Summary Treatment of cancer of the cervical aerodigestive tract is challenging due in part to the difficulty in reestablishment of pharyngoesophageal continuity after resection of the involved tract. From May 1989 to August 1990, six patients underwent immediate reconstruction utilizing microvascular transfer of free radial forearm flaps following resection of pharyngoesophageal neoplasms. A small island flap connected to the radial vascular pedicle by fasciocutaneous branch was used to monitor the vascular condition of the hidden fabricated free forearm flap. Stricture is the most troublesome complication of esophageal reconstruction using a conventional free forearm flap. Two small triangular flaps were designed and inserted bilaterally in the distal anastomosis of both lateral esophageal walls to prevent circular contracture. The outer layer sutures were anchored to surrounding rigid structures to withstand shrinkage and circular contraction. The problem of stricture was solved by these procedures. This one-stage, easily monitored operation for pharyngoesophageal reconstruction is considered to be as useful as a free jejunal transfer.
