Autologous Fat Grafting for the Treatment of a Painful Neuroma of the Hand: A Case Report and Review of Literature

Neuropathic pain caused by a neuroma can have a significant effect on daily life. Current surgical treatments include simple neuroma excision and proximal nerve stump relocation (into a muscle, vein, or bone). We describe a patient who presented with neuropathic pain, restricted to the dorsum of the right hand, and numbness of the dorsum of the radial half of the middle finger. The patient is a right-handed architect and due to the trauma could no longer shake hands for fear of pain. Her Tinel's test was strongly positive. In 2015, she was diagnosed with a neuroma-in-continuity of the third digital nerve originating from the superficial branch of the radial nerve. At the time she was treated with an on-site Naropin injection and hand rehabilitation therapy, which ultimately alleviated the pain. Three years later she presented with pain progression whereupon we treated her exclusively with AFT. The patient was followed up for 12 weeks after the operation; the pain completely disappeared and the patient could shake hands again. After one year, she was still pain-free. AFT is a new technique for the treatment of persistent neuropathic pain and numbness in the hand caused by blunt-trauma neuroma. Autologous fat grafting is a safe, effective, minimally invasive, and innovative therapeutic approach for the management of painful neuromas.
