The results of operation on 71 volar wrist ganglia are reported. The recurrence rate was 28%, occurring between 1 and 144 months (median: 5 months). The highest risk of recurrence is in a male patient, under 30 years of age, in a manual occupation, operated on by a junior surgeon. The use of a post-operative plaster slab seemed to be followed by significant wrist stiffness. 28% of the patients had evidence of damage to the palmar cutaneous branch of the median nerve. It is suggested that this could be avoided by positive identification of this nerve at operation.
