Fifty-one skeletally immature cerebral palsied (C.P.) children with 70 subluxated or dislocated hips were treated by conservative methods: femoral osteotomy (65 hips), pelvic osteotomy (52 hips) and arthrotomy when necessary (19 cases). 31 children were less than 10 years of age when operated on (mean 6 years, 6 months), 20 children were more than 10 years of age (mean 13 years, 13 months); mean follow-up was 4 years. Reduction and coverage were achieved and maintained in all patients, except for 6 redislocations: a pelvic obliquity was neglected in 3 cases; femoral shortening was not performed in 2 cases. Post-operative course was difficult in eldest patients with pain and stiffness but functional result was acceptable at follow-up in all cases except redislocations. Open reduction was related to a higher rate of postoperative rehabilitation problems. Modeling of previously deformed femoral heads and improvement of hip mobility were consistently seen at last follow-up, except for 3 redislocations. It is concluded that conservative methods are quite advisable in CP children and adolescents. Hip reduction should be preferred to femoral resection even in adolescent.

Psychophysical measurements were made of the sensory effects of l-menthol applied topically to the forearm under controlled thermal conditions. In the first experiment, subjects judged the intensity and quality of sensations produced by warming or cooling the skin in the presence of menthol or the vehicle. During cooling, menthol intensified cutaneous sensations and increased reports of burning. During warming, menthol intensified sensations transiently at low temperatures and weakened them lastingly at higher temperatures; the frequency of reports of burning varied with intensity. A second experiment tested the hypothesis that menthol would lower the threshold for warmth and raise the threshold for heat pain. No change in either threshold was observed. The primary sensory effects of l-menthol on hairy skin are therefore to heighten the perception of cooling and to attenuate the perception of moderate warming. In contrast with other common chemical irritants, menthol's pungent qualities appear to be enhanced by cooling and suppressed by warming; this suggests that its sensory irritancy may be attributable to the stimulation of a population of high-threshold cold fibers or cold-sensitive nociceptors.

Fifty-one meniscectomies by arthroscopy were realised on patients of more than 55 years of age between 1981 and 1986. Twenty-four patients were reviewed after at least 4 years of follow up, 12 of them after a 7.5 years follow up. 21 results were noted as functionally very good or good, 3 were poor. The radiological analysis of femoro-tibial compartments in comparison with the non operative side showed a clear pejorative difference in one case, moderate in 5 without incriminating the morphological type. If the quality of result does'nt correlate with age, it was'nt the same for the type of lesion seen during arthroscopy, the best results after arthroscopic meniscectomies were seen in traumatic lesions occurring on normal menisci or on degenerative ones. The authors concluded that medial meniscectomy in patients older than 55 years is justified in precise indications: a known traumatism or also acute medial pain, or speedy with normal or subnormal X-ray and after a positive arthrography.

The authors compared the long term follow-up (mean duration 19 years) of 96 patients operated on for hallux valgus, 52 by the McBride procedure, 46 by a Hohmann procedure. Clinical results considered 4 criteria: deformity, pain, mobility and satisfaction. Dorsoplantar weight bearing X-ray compared anatomical results. This study showed that patients were subjectively more satisfied after McBride operation (p = 0.0001) even if the deformity was radiologically better reduced by osteotomy (p = 0.006). This discrepancy between subjective and radiologic results was related to the fact that X-rays represent only the static morphologic reflect of a more complex pathologic entity: radiology can only partly explain the functional discomfort of the patients. The modified McBride procedure was better suited to patients presenting a painful HV. Osteotomy was more suited to bunions causing little pain. Indications for each of these procedures should be based more on patient's history and clinical examination than on X-rays.

Fifty-four rheumatoid wrists, on which synovectomy and caput ulnar resection had been performed, were re-examined 1 to 8 years after the operation (average follow-up: 3.8 years). The clinical results were good, and the wrists pain-free in 91 per cent of cases, with a low rate of synovitis recurrence (4 per cent), and 88 per cent of the mobility in the sagittal plane was preserved. Radiological examination revealed a moderate aggravation of carpite over the years. This evolution was not linked, however, to the fact that no intracarpal synovectomy was performed in our series since a similar evolution has been reported by authors who carry out this synovectomy. Ulnar translocation of the carpus was commonly measured in relation to the ulna axis, but as the latter tends to get into a more medial position after the surgery this analysis was incorrect. Ulnar translocation should be measured in relation to the axis of the radius, which remains in the same position. Studied in this way, the average translocation in this whole series was 2 mm. A comparative study of the operated wrist and the non-operated wrist in 27 patients revealed a significant aggravation (p < 0.2) of ulnar translocation of the carpus at radiological stages 2 and 3. This translocation remained however minimal. A combined transfer of the extensor carpi radialis brevis or longus onto the extensor carpi ulnaris did not slow down ulnar translocation of the carpus, but the other hand it improved the correction of radial deviation of the carpus and ulnar deviation of the fingers.

Fifty patients who underwent a total denervation of the wrist were reviewed after an average of 5 years post-operatively. The main aetiology was diffuse osteo-arthritis secondary to scaphoid nonunion (44 per cent) and Kienbock's disease, stage IV (22 per cent). This resulted in pain and functional disability. Another surgical procedure was carried out in 40 per cent of patients. Post-operative complications included one painful neuroma and 3 patients complained of radial nerve paraesthesia. Pain was improved in 36 of the 50 patients with an average score of 72 over a scale of 100. There was no significant change in power or range of movement.

It is generally accepted that the sensory and affective components of pain may be differentially associated with various acute and chronic diseases, and that some treatment regimens are best directed toward certain aspects of the pain experience. In addition, experimental animal models have been described that presume to assess either the sensory-discriminative aspects of phasic pain or the affective responses associated with tonic pain. The present psychophysical experiment directly compares the perceived intensity and unpleasantness of sensations evoked by four types of experimental noxious stimuli: contact heat, electric shock, ischemic exercise, and cold-pressor pain. A novel pain measurement technique is described that incorporates unbounded magnitude-estimation/category scales; this technique allows precise ratio responses, while minimizing within- and between-subject variability. We observe that, relative to the perceived intensity of the individual stimuli, subjects consistently differentiate among the degrees of unpleasantness evoked by the four stimulus modalities. Ischemic exercise and cold-pressor pain evoke higher estimates of unpleasantness, and thus may better mimic the pain of chronic disease. The relative unpleasantness produced by contact heat is significantly less than that of the other modalities tested, and therefore contact heat stimuli may be ideally suited for assessing sensory-discriminative aspects of pain perception. Possible neurophysiological mechanisms underlying the observed differences in perceived unpleasantness are discussed in relation to the growing body of literature concerning tonic and phasic pain stimuli.

Two cases of tarsal tunnel syndrome caused by lipoma are reported. Both patients had ankle pain that radiated to the sole for years. On physical examination, localized swelling behind medial malleolus was found. Tinel's sign was provoked by gentle percussion on the posterior tibial nerve and its branches. Electrophysiological study showed fibrillation in foot intrinsic muscles or prolongation of motor and sensory latency of plantar nerves. Computed tomography of the tarsal tunnel demonstrated areas of low density indicating masses of high lipid content. Exploration of tarsal tunnel revealed compression of the medial plantar nerve by a lipoma. After excision of the lipoma, both patients had complete relief of ankle and foot pain. Computed tomography is helpful in delineating the nature and extent of lipoma within the tarsal tunnel.

75 subjects were randomly assigned to five self-efficacy conditions (High-High, High-Low, Low-High, Low-Low, and Control) in a 5 x 3 (condition x trial) design. Pressure was applied three times to an exposed finger. After baseline, subjects received false biofeedback (i.e., independent of ratings of pain) that their ability to regulate intensity of pain was either good (High-High and High-Low) or poor (Low-High and Low-Low), or there was no biofeedback (Control). After a second trial, subjects were told that their biofeedback indicated either good (High-High and Low-High) or poor (High-Low and Low-Low) regulatory ability, or they were not given biofeedback (Control). They then received a final trial. Before each trial, subjects recorded self-efficacy expectations for regulating intensity of pain. Mixed multivariate analyses of variance on ratings of intensity and self-efficacy expectations did not yield hypothesized interactions for condition x trial.
