RESUMO
Bilateral injuries of the sensory branch of the radial nerve (SBRN) usually occur as a result of tight-handcuff neuropathy. In this case we aimed to present bilateral isolated cut of SBRN resulting an injury mechanism that has not been reported in the literature previously. A male twenty-four years old, a worker in a glass factory, presented to our clinic. The dorsolateral skin of his wrists were cut by breaking of the glass as a result of occupational accident and was primarily sutured in a healthcare center. The patient sought additional care after a month because of lingering numbness and pain, and surgery was planned. During surgery, scar tissue and neuroma at the cut ends of SBRN were excised, and bilateral SBRN cuts were repaired. Four weeks after operation, mild sensory deficit on the dorsal side of bilateral thumbs, and left first web space and flexion limitation on the right wrist were detected. At the 3rd month postoperative, right wrist joint range of motion was full, and sensory deficits, and hyperesthesia were decreased. The SBRN elicits the sensory innervation of the thumb dorsum and its injury does not cause important functional deficit. However because of susceptibility of SBRN to develop painful neuroma, diagnosis, treatment and follow up of isolated SBRN injury would be worthwhile for prevention of possible painful neuropathy disturbing quality of life.
