Outcome Measures
Primary Outcomes (6)
Patient-Reported Outcomes Measurement Information System - Pain Interference (PROMIS-PI)
PROMIS Pain Interference (PROMIS-PI) scale measures the extent to which pain hinders an individual's engagement with physical, mental, cognitive, emotional, recreational, and social activities over the past 7 days answering each questions with a response of not at all, a little bit, somewhat, quite a bit, and very much with not at all being the best and very much the worst.
Assessing change from Baseline to 1 week, 1 month, 3 months and 6 months
Short-form McGill Pain Questionnaire (SF-MPQ-2)
theShort-form McGill Pain Questionnaire (SF-MPQ-2) measures 24 different qualities of pain and related symptoms using the intensity of pain and related symptoms felt during the past week on 0 to 10 scale, with 0 being no pain and 10 being the worst pain .
Assessing change from Baseline to 1 week, 1 month, 3 months and 6 months
PROMIS Global Health (GH) v1.2
The Global Health Questionnaire contains 10 questions (7 general and 3 about the last 7 days). First 7 questions use a scale of excellent, very good, good, fair, and poor, poor being the worst with excellent being the best. The other three questions use different scales such as; never rarely, sometimes, often or always with never being the best and always being the worst; as well as none, mild, moderate, severe, very severe with none being the best and very severe being the worst; finally pain rating numbered 0-10 with 0 being no pain and 10 being the worst pain imaginable.
Assessing change from Baseline to 1 week, 1 month, 3 months and 6 months
Patient Health Questionnaire (PHQ-9),
The PHQ-9 form is a brief, self-administered questionnaire that assesses depression symptoms over the last 2 weeks consisting of 10 questions. 9 will be answered on a scale of 0-3 with 0 being the best and 3 bing the worst. The last question will use a response of not difficult at all, somewhat difficult, very difficult, and extremely difficult with not difficult at all being the best and extremely difficult being the worst.
Assessing change from Baseline to 1 week, 1 month, 3 months and 6 months
Generalized Anxiety Disorder measure (GAD-7),
Generalized Anxiety Disorder measure (GAD-7) is a screening tool and severity measure for generalised anxiety disorder (GAD) over the past 2 weeks consisting of 7 questions answered on a scale of 0-3 with 0 being the best and 3 being the worst.
Assessing change from Baseline to 1 week, 1 month, 3 months and 6 months
PC-PTSD-5
The Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) is a 5-item screening tool with 'Yes/No" answers designed to identify individuals with probable PTSD. Yes" answers represent the worst and "no" represents the best.
Assessing change from Baseline to 1 week, 1 month, 3 months and 6 months
Secondary Outcomes (13)
PROMIS UpperExtremity (UE)
Assessing change from Baseline to 1 week, 1 month, 3 months and 6 months
Brief Michigan Hand Outcomes Questionnaire (bMHQ)
Assessing change from Baseline to 1 week, 1 month, 3 months and 6 months
Grip Strength
Assessing change from Baseline to 1 month, 3 months and 6 months
Pinch Strength -Key and Three-point
Assessing change from Baseline to 1 month, 3 months and 6 months
Range of Motion
Assessing change from Baseline to 1 month, 3 months and 6 months

Study Arms (2)
Regenerative Peripheral Nerve Interface
symptomatic neuroma is excised, and the end of the peripheral nerve is implanted into a small denervated free muscle graft harvested from the patient
Traction Neurectomy
simple excision and traction neurectomy
Interventions
Surgeons will perform neuroma resection and RPNI creation using a free muscle graft from the brachioradialis muscle harvested through a small separate incision
Surgeons will perform neuroma resection and traction neurectomy,
Eligibility Criteria
Patients 18 years or older with a history of digit, multi-digit or partial hand amputation. Patients must have discrete neuroma pain on clinical exam.
You may qualify if:
- years or older
- History of unilateral digit, multiple digit, or partial hand amputation
- Discrete neuroma pain on clinical exam
- Following standard of care (SOC), confirmation through a local block and/or ultrasound imaging will be performed if indicated
- Must be seen by a hand therapist for at least 6-week trial of desensitization therapy
You may not qualify if:
- Patients with previous surgical treatment for symptomatic neuromas of the digits or hand
- Patients with other major injuries more proximal in the ipsilateral extremity that cause chronic pain or functional loss
- women pregnant at time of enrollment
- prisoners
- adults who are unable to consent
