I proceeded next with the right thumb.* A longitudinal incision was designed over the ulnar midlateral aspect of the thumb, centered over the IP articulation.* The incision was carried down through the subcutaneous tissues.* Soft tissue dissection was performed extensively in this area.* The ulnar digital nerve was identified and carefully protected throughout the duration of surgery.* The trifurcation point and the resultant sensory nerves were also identified and protected.* There was no evidence of soft tissue mass.* There was no evidence of cystic lesion in this particular area.* A small longitudinal incision was made over the collateral ligament.* There was no evidence for cyst embedded or buried within this particular area.* I was not able to identify a glomus tumor or a nerve sheath tumor of any sort.
Following extensive dissection and neurolysis, skin closure was performed.
