Multiple digital branch involvement of the median nerve by schwannoma: case report

A case of multiple digital branch involvement of the median nerve by a schwannoma is described in this case report. The benign tumor had grown for almost 30 years and infiltrated the digital nerves 1, 2 and 3. As a result the patient’s daily life activities became increasingly affected. After examination and definite evaluation of the tumor entity being a schwannoma, planning of the surgical treatment strategy included total resection of the schwannoma formations and the affected nerves. In a single-step-operation the nerves were grafted using a sural cable graft which was harvested from the right calf and divided into three nerve grafts. During the 4-year clinical follow-up the patient showed no loss in grip strength and pinch grip strength. The two-point static discrimination revealed 8 mm for N1 and N2, 9 mm for N3 and 7 mm for N4. Subjectively his use of the affected hand was unlimited.
