Regenerative Peripheral Nerve Interfaces to Treat Painful Digit and Hand Neuromas After Amputation: A Prospective Observational Trial"
Summary
This study is being done to demonstrate the effectiveness of Regenerative Peripheral Nerve Interfaces (RPNI) surgery in treating symptomatic neuromas of the hand and digits following amputation compared to standard of care using a Prospective, Observational Trial
Detailed description
This will be a prospective observational study that seeks to provide a comprehensive assessment of the outcomes after RPNI surgery compared to standard of care by utilizing multiple established and validated patient-reported outcomes measures, carefully tracking pre- and post-operative pain regimens, and performing functional and physiologic tests.
Arms & interventions
- ProcedureRegenerative Peripheral Nerve Interface (RPNI) surgery
Surgeons will perform neuroma resection and RPNI creation using a free muscle graft from the brachioradialis muscle harvested through a small separate incision
- ProcedureTraction Neurectomy
Surgeons will perform neuroma resection and traction neurectomy,
Outcome measures
Primary
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.
Time frame: 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 .
Time frame: 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.
Time frame: 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.
Time frame: 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.
Time frame: 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.
Time frame: Assessing change from Baseline to 1 week, 1 month, 3 months and 6 months
Secondary
PROMIS UpperExtremity (UE)
Time frame: Assessing change from Baseline to 1 week, 1 month, 3 months and 6 months
Brief Michigan Hand Outcomes Questionnaire (bMHQ)
Time frame: Assessing change from Baseline to 1 week, 1 month, 3 months and 6 months
Grip Strength
Time frame: Assessing change from Baseline to 1 month, 3 months and 6 months
Pinch Strength -Key and Three-point
Time frame: Assessing change from Baseline to 1 month, 3 months and 6 months
Range of Motion
Time frame: Assessing change from Baseline to 1 month, 3 months and 6 months
Fine Motor Function - 9-Hole Peg Test (9HPT)
Time frame: Assessing change from Baseline to 1 month, 3 months and 6 months
FunctionalTask Testing - Lifting boxes
Time frame: Assessing change from Baseline to 1 month, 3 months and 6 months
Functional Task Testing - Carrying Boxes
