Bullosis diabeticorum following carpal tunnel decompression.

A 76-year-old gentleman underwent carpal tunnel decompression on his right dominant hand under local anaesthesia. He was diabetic and otherwise healthy. He presented 3 days after with ischaemic blisters of his lateral three and a half fingers on the finger tips. This complication following carpal tunnel decompression or following the use of local anaesthetics at the wrist has not been documented so far in the literature on the PUBMED data base. The authors wish to highlight this rather unusual complication encountered following this common procedure in orthopaedic surgical practice.
