    Notes: Abstract Although many pathological changes in the internal capsule may lead to neurological deficits, we often encounter ill-defined focal low attenuation in the posterior limb of the internal capsule (PIC) on CT in patients with no neurological disturbance. Brain CT studies of 141 patients without neurological deficites were reviewed to investigate the position of the focal low attenuation by analysis of a profile density curve. Nine patients with lacunar infarcts only within the posterior internal capsule were also studied. The focal low attenuation areas were ill-defined and bilaterally symmetrical, without mass effect. They were seen consistently within the posterior limb of the posterior internal capsule. Correlation between the distribution of these foci and the position of lacunar infarcts in the posterior internal capsule in nine patients with neurological deficits suggests that they may be related to the corticospinal tract.

    Description / Table of Contents: Résumé Une gélatine de matrice osseuse préparée par un traitement chimique séquentiel comportant une décalcification par l'acide chlorhydrique a été utilisée comme implant allogène dans le traitement des tumeurs osseuses, bénignes ou malignes, des dysplasies acétabulaires, des retards de consolidation, des pertes de substance traumatique, etc. Cette gélatine de matrice osseuse mise en place dans les cavités osseuses a été réhabitée avec succès 97 fois sur 99 (98%), à l'exclusion des cas d'infection ou de récidive de la tumeur. L'implant a également été placé à la surface de l'os, en inlay, dans 10 cas mais il s'est résorbé 5 fois, sans formation d'os. La réhabitation a été obtenue dans un délai de 6 à 33 mois (14,9 en moyenne). Une infection est survenue 5 fois sur 165 implantations (3%) sur des lésions osseuses antérieurement aseptiques. Une fièvre modérée persistant plus de dix jours après l'opération (traduisant probablement une réaction immunologique) a été observée 4 fois sur 160 implantations (2,5%), à l'exclusion des cas infectés. Les implants allogènes de matrice osseuse constituent donc un traitement efficace des pertes de substance osseuse avec un faible risque de complications, rejet ou infection.
    Notes: Summary Bone matrix gelatin, prepared by sequential chemical treatment including decalcification with 0.6 N hydrochloric acid [9], was used as an alloimplant for the treatment of benign bone tumours, tumorous conditions of bone, acetabular dysplasia, delayed union, traumatic bone defects and other disorders. The bone matrix gelatin implanted into bone defects was incorporated successfully in 98% of implantations, excluding cases of infection, tumour recurrence and recurrence of tumorous conditions. The material was also implanted into ten bone sites as an onlay but in five it was resorbed without new bone formation. The incorporation of the bone matrix gelatin into the recipient bed was completed from 6 to 33 months (average 14.9 months) after implantation. Wound infection complicated 5 of 165 implantations (3%) in previously uninfected sites. Low grade fever persisting after the tenth post-operative day (a probable sign of immunological reaction) occurred in 4 of 160 implantations (2.5%), excluding cases of infection. Alloimplants of bone matrix gelatin are thus effective in the treatment of bone defects. The risk of complication such as rejection or infection is low.
