We reviewed 48 arthrodeses of the carpometacarpal joint of the thumb in 39 patients being treated for osteoarthritis. The mean follow-up period was 90 months (range 14 months-17 years). In 28 (58%) hands pain relief was excellent and in 6 (12%) good. Mobility was significantly reduced ( p < 0.002). Mean key pinch (52.9 N) and grip strength (219.5 N) were comparable with the unoperated hand (51.0 and 239.1 N, respectively). Hand function was near normal. In 29 hands an additional operation was needed to remove the osteosynthesis material; 14 hands failed to unite. Osteoarthritis of the scaphotrapezial joint increased significantly faster in the operated hands than in the unoperated ones ( p < 0.0001). A soft tissue procedure (such as flexor carpi radialis interposition arthroplasty) is advised instead of arthrodesis, because of the large number of reoperations, based on non-union and removal of the osteosynthesis material. From a survey of published papers we conclude that arthrodesis of the carpometacarpal joint of the thumb can best be done by stapling and bone grafting. 相似文献

The aim of the present study was to examine visual attention, especially the executive control functions that deal with conflict,
when participants were in a low arousal state shortly after a nighttime awakening. Fifteen participants spent four consecutive
nights at a laboratory and performed a flankers task using two levels of target-distractor spacing (0.75° and 1.50°) and three
trial types (compatible, incompatible, and neutral). The first night was a habituation night. For the next three nights, participants
went to sleep at 2300 hours and were then awakened at either 2400 hours (1-h sleep bout), 0300 hours (4-h sleep bout), or
0600 hours (7-h sleep bout) and were administered a flankers task and a self-report questionnaire that measured arousal level.
These testing times were counter-balanced across participants, and a 2100 hours (pre-sleep) flankers task was also randomly
assigned to be completed on one of the testing nights. Response time on neutral-flanker trials was increased if participants
were awakened from a sleep bout and was slowest at 0300 hours, appearing to parallel circadian body temperature. In contrast,
failures of selective attention, as indexed by the difference between compatible and incompatible trials, increased linearly
as a function of the length of the sleep bout. Compared to the 2100 hours pre-sleep condition, self-reported energy was lower
and Tiredness was higher after awakening from a sleep bout. Taken together, the current data suggest a dissociation between
the processes that perform a non-conflict task and the executive control of attention. Specifically, longer sleep bouts seem
to be associated with greater difficulty in inhibiting task-irrelevant information, perhaps due to a sleep inertia effect
affecting the anterior cingulate cortex. 相似文献
