Equinus deformity of the foot in cerebral palsy is observed most frequently as the factor of impeading the gait and the standing. Although numerous operative methods were contrived for it since old times, the problem of recurrences of the deformity, the weaknes of muscle and etc. were observed frequently. In our educational institution, we have corrected the deformities of 146 patients since 35th of Showa. We could recently trace 51 feet of 33 patients.
We have corrected these patients chiefly by gastrocnemius recession contrived by Vulpius, Strayer and so on or lengthening of the tendo calcaneus. In the results, we observed quite numerous recurrences in the gastrocnemius recession group. However gastrocnemius recession has given relatively good results to paraplegia but bad to monoplegia. There were few patients who have weakness of plantar flexor. As there were few patients operated by lengthening of the tendo calcaneus, we could not compare it with gastrocnemius recession.
