    Description / Table of Contents: Résumé.  57 ténotomies des adducteurs ont été réalisées chez 30 enfants IMC tétraparétiques spastiques. A 23 reprises, une neurotomie obturatrice a été associée au geste de ténotomie. Le recul moyen était de 6 ans et 3 mois (2A–20A). Nous avons jugé nos résultats avec l’indice de Reimers et établi 3 groupes selon sa valeur. Cet indice était inférieur à 20% dans le groupe A (2 hanches), compris entre 20 et 40% dans le groupe B (25 hanches), et supérieur à 40% dans le groupe C (20 hanches). Au plus long recul une nouvelle analyse de cet indice a été réalisée. On a considéré qu’il avait amélioration quand l’indice avait diminué de 10% par rapport aux clichés pré-opératoires, aggravation quand il avait augmenté de 10% et stabilisation quand sa variation était comprise entre –10 et +10%. Dans le groupe A, 11 hanches se sont stabilisées (92%) et 1 s’est aggravée. Dans le groupe B, 12 hanches se sont stabilisées (48%), 7 se sont améliorées (28%) et 6 se sont aggravées (24%). Dans le groupe C, 7 hanches se sont stabilisées (35%), 13 se sont aggravées (65%) et aucune ne s’est améliorée. En conclusion le facteur prédictif essentiel reste l’indice de Reimers. L’âge de l’enfant au moment de l’intervention ne semble pas influer de manière évidente sur le résultat final, pas plus que l’association d’une neurotomie obturatrice.
    Notes: Summary.  This study reviewed 57 hips in 30 children (18 girls and 12 boys) with cerebral palsy who had undergone an adductor tenotomy alone or in combination with an anterior obturator neurectomy (23 hips). Results were evaluated by the Reimers migration percentage (MP). The hips were split into three groups: group A (12 hips) a preoperative MP of less than 20%, group B (25 hips) between 20 and 40%, and group C (20 hips) more than 40%. The mean age at the time of surgery was 6 years and 1 month (range: 2.5–13 years). The mean period of review was 6 years and 3 months (2–20 years). The results were considered as ”good” when radiographs at the longest follow-up showed a decrease of 〉10% of the MP, as ”bad” when they showed an increase of 〉10%, and as ”stable” when the MPs varied less than 10%. At the latest review of group A, 11 were stable (92%) and 1 was bad. In group B, 12 were stable (48%), 7 were good (28%), and 6 were bad (24%). In group C, 7 were stable (35%), and 13 were bad (65%). The preoperative migration percentage proved to be the only predictor of outcome. Age at the time of surgery had no constant significant effect on the outcome, neither had the addition of an anterior neurectomy.

    Notes: Abstract. Technetium-99m sestamibi (MIBI), an alternative radiopharmaceutical for myocardial perfusion imaging, has also been proposed for use as an imaging agent for various tumours, including breast cancer, lung cancer, lymphomas, melanomas and brain tumours. After routine radiation therapy, deteriorating clinical status or treatment failure may be due to either radiation-induced changes or recurrent tumour. Computed tomography and magnetic resonance imaging offer imperfect discrimination of tumour viability and radionecrosis. Against this background we undertook a retrospective study of 35 malignant glioma patients in whom clinical deterioration had occurred, in order to clarify the value of 99mTc-MIBI SPET in identifying tumour recurrence. SPET was performed 15 min after intravenous injection of 1110 MBq 99mTc-MIBI. The images were obtained with a dual-headed gamma camera using a fan-beam collimator. Transverse, coronal and sagittal views were reconstructed. Intense MIBI uptake was found in 31 patients. This uptake was correlated with tumour recurrence as proved by histology and/or rapid, fatal evolution of these cases. The statistical analysis performed on this population of patients with MIBI uptake revealed a group of patients with a long mean survival and a group with a short mean survival. Two subgroups were found within each of these groups, according to the functional index ratio (tumour uptake/pituitary gland uptake ratio). No MIBI uptake was found in four patients who are still alive and can be considered to be disease-free. In those cases showing MIBI uptake, death occurred an average of 6.69 months following brain SPET. According to our results, the specificity and sensitivity of 99mTc-MIBI brain SPET seem to be high. Moreover, this technique is more accurate than computed tomography or magnetic resonance imaging for discriminating between tumour recurrence and radionecrosis.
