Morton's neuroma is regarded as a type of entrapment neuropathy, therefore, 
neurolysis as surgical treatment is preferable to neurectomy. We have developed 
a new surgical procedure which consists of a plantar zigzag incision, incision 
of the plantar aponeurosis, and microsurgical neurolysis of the interdigital 
nerve. We have performed this operation on 6 nerves with Morton's neuroma in 5 
patients and obtained excellent results. The remaining one nerve showed fair 
results. Neurectomy of the interdigital nerve has been regarded as the surgical 
treatment of choice for Morton's neuroma. However, a resection neuroma and 
permanent sensory deficit are inevitable sequelae after neurectomy. Since 
Morton's neuroma is considered to be a type of entrapment neuropathy, it is 
reasonable to think that neurolysis is preferable to neurectomy. We have 
developed a renewed procedure of microsurgical neurolysis on nerves involved 
with Morton's neuroma. Using this procedure, we operated 6 nerves with Morton's 
neuroma on 5 patients and obtained excellent results, which forms the basis of 
this report.
