简要总结
Neuromas are a common complication after digital and hand amputations, resulting in significant pain, discomfort, and functional impairment. Various management methods are available, including surgical excision, nerve blocks, and nerve stump protectors, but these treatments may have limited success rates and potential complications. Targeted muscle reinnervation (TMR) is a promising technique that involves surgically rerouting a severed nerve into a nearby muscle, which can prevent the formation of neuromas and provide improved muscle function

研究组 & 干预措施
targeted muscle reinervation post digit amputation group
In 1ry TMR ,after the amputation is performed by the standard method , transected nerves will be replanted micro surgically to motor entry points (MEPS)in the hand as predetermined by Daugherty et al , Motor branches in the recipient muscles could be determined by a nerve stimulator intraoperatively.
In 2ry TMR , neuroma site will be explored and it will be excised ,the distal end of the transected nerve will be connected micro surgically to the nearest MEPS
干预措施: Targeted muscle reinnervation (Procedure)
结局指标
主要结局
Pain character
时间窗: will be taken at intervals over time (1 month, 3 months,6 months, 9 months,1 year until the conclusion of the study
Leeds Assessment of neuropathic symptoms and signs pain scale is a valuable tool designed to evaluate and categorize pain. Its primary purpose is to determine if nerve damage is the primary cause of the pain, distinguishing between neuropathic and nociceptive pain. The scale comprises seven items, divided into two sections. The first part consists of five questions related to symptoms experienced by the individual. The second part involves two clinical examination items that are typically conducted in collaboration with a healthcare provider. A score of 12 or more on this scale confirms a diagnosis of neuropathic pain to some degree. Scores below 12 are less likely to show neuropathic pain
Neuroma incidence
时间窗: through study completion, an average of 1 year
Neuroma incidence post TMR operation is recorded via Tinel's sign
Neuroma recurrence
时间窗: through study completion, an average of 1 year
Neuroma recurrence in cases of 2ry TMR cases
Pain intensity
时间窗: will be taken at intervals over time (1 month, 3 months,6 months, 9 months,1 year until the conclusion of the study
measured using pain rating numerical scale commonly used to assess pain severity at that moment in time using a 0-10 scale, with zero meaning "no pain" and 10 meaning "the worst pain imaginable
