Randomized Controlled Trial Comparative Study Clinical TrialComparison between single injection transthecal and subcutaneous digital blocks.
A randomized double blinded study was performed on 142 patients to evaluate two different techniques of single injection digital anaesthesia. In group A, 86 digits in 71 patients were anaesthetized by a single injection transthecal technique using 3 cc of lignocaine and bupivacaine mixture. ⋯ Total anaesthesia of the digit was achieved in 75 (94%) digits. These two techniques were found to have no differences in effectiveness, distribution, onset and duration of anaesthesia.

X-ray characteristics of wrists in calcium pyrophosphate crystal deposition disease. Is pseudogout a major cause of scapholunate advanced collapse?
Deposition of calcium pyrophosphate dihydrate (CPPD) crystals has been considered to be a cause of scapholunate advanced collapse (SLAC) wrist. The aim of this study was to look at X-ray changes in wrist joints affected by CPPD crystal deposition disease and to determine whether crystal deposition is a cause of SLAC wrist. ⋯ In our population of Japanese patients with CPPD crystal deposition disease, the incidence of SLAC wrist was very low, and no case of Stage III SLAC wrist was found. We therefore conclude that SLAC wrist is not a radiographic characteristic of CPPD crystal deposition disease and that pyrophosphate crystal deposition cannot be a major cause of SLAC wrist.
