    Notes: Summary  To appraise the validity, intra-operative elevation of hand temperature ensuring a successful T2-sympathectomy, we conducted a randomized, self-compared, case-control study on 40 consecutive patients with palmar hyperhidrosis. All patients had a postoperative follow-up of at least 18 months without recurrence. During operation, dynamic temperature changes on their thenar eminence of both the surgically treated and non-surgically treated hands were simultaneously measured just before (baseline) and after completion of T2-sympathectomy, and again 5 and 10 minutes later. An elevation of the temperature by at least 0.5°C from the baseline temperature was recognized as an “elevated” temperature. The relationship between sensitivity and specificity of temperature changes was compared using receiver operator characteristic (ROC) analysis. Sensitivity was defined as the proportion of temperature-elevating procedures in the group of operated hands. As a whole, post-sympathectomy elevation of hand temperature is a useful, but not an ideal, indicator for assuring a successful T2-sympathectomy due to its low sensitivity. At the 5-minute point, if the hand temperature was elevated by 1°C, its sensitivity, specificity and positive predictive value were 40%, 80% and 66.7%. In comparison, a 2°C elevation at the 10-minute point had a sensitivity, specificity and positive predictive value of 30%, 90% and 75% (p〈0.05). We suggest that correct localization of the T2 ganglion followed by adequate ablation should be the prerequisite for use of this monitoring system.

    Description / Table of Contents: Résumé Les auteurs présentent une revue de 50 genoux, chez 42 malades, opérés entre août 1973 et novembre 1976. Après de bons résultats initiaux, sont apparus divers problèmes. Les complications provenant de fautes dans le dessin de la prothèse, dans le choix des malades et du fait d'obstacle techniques sont analysées. Ce type de prothèse ne convient pas aux malades dont les genoux sont très instables et déformés. La crête médiane de polyéthylène à haute densité de la pièce tibiale n'est pas suffisamment forte pour résister aux contraintes en valgus ou en varus. La correction totale du valgus, du varus ou du flessum est essentielle pour éviter les complications tardives. La déformation associée en rotation externe des genoux ayant un important valgus doit être totalement corrigée si l'on veut éviter la survenue d'une luxation de la rotule. En conclusion, à l'heure actuelle, les prothèse avec et sans charnière ont toutes deux une place dans l'arthroplastie totale du genou.
    Notes: Summary A review of 50 knees in 42 patients operated upon between August, 1973 and November, 1976 is presented. Following initial good results, problems have been encountered with the passage of time. Complications due to design faults, selection, and technical pitfalls are analysed. Patients who have grossly unstable and deformed knees are not suitable for this type of prosthesis. The high density polyethylene central flange in the tibial component is not strong enough to withstand valgus or varus forces. Full correction of valgus, varus, or flexion deformities is essential if late complications are to be avoided. Associated external rotation deformities in grossly valgus knees have to be fully corrected to prevent late dislocation of the patella. Our conclusion is that at present there is a place for both the hinged and hingeless type of prosthesis in total knee replacement.
