“…It is imperative to choose a first step radical treatment in order to avoid recurrence and metastases. In this regard, to be initially aggressive in the eradication of the tumor, may lead to a safer level of amputation thus increasing the surface area of healthy tissue available for eventually subsequent reconstruction and prothesization (48)(49)(50)(51)(52)(53)(54)(55). Moreover it potentially decreases patient's number of treatments, hospital stay and last but not least, could reduce sanitary burden related to complex medical dressings and hospital care.…”

“…First, muscular structure can be signi cantly altered due to surgical management. Speci cally, for transradial amputation, myodesis of deeper forearm muscles and myoplasty of super cial muscles are needed for bone coverage and contraction stability post-surgery [55]. These procedures, as well as retractions and brosis after surgery, may alter the conduction of the muscle unit action potentials within the forearm tissue due to changes of the source signal locations and tissue conductivity.…”

Background Establishing a natural communication interface between the user and the terminal device is one of the central challenges of hand neuroprosthetics research. Surface electromyography (EMG) is the most common source of neural signals for interpreting a user’s intent in these interfaces. However, how the capacity of EMG generation is affected by various clinical parameters remains largely unknown. Methods In this retrospective study using an open source database, we examined the EMG activity of forearm muscles recorded from 11 transradially amputated subjects and 40 able-bodied subjects who performed a wide range of movements. By using non-negative matrix factorization, we extracted the synergistic EMG patterns for each subject to estimate the dimensionality of muscle control, under the framework of motor synergies. Results We found that amputees exhibited less than four synergies (with substantial variability related to the length of remaining limb and age), whereas able-bodied subjects commonly demonstrate five or more synergies. Conclusions The results of this study provide novel insight into the muscle synergy framework and the design of natural myoelectric control interfaces.

“…The performance of a successful amputation at each level of the limb permits supreme usage of the remaining extremity, with or without a prosthesis, and reduces the known complications of such injuries [17]. As hand transplantation has come to be more common, many significant problems have appeared.…”

Over the recent past few years, there is a huge innovation in plastic surgery and orthopedic surgery through implantation of new techniques, which enabled a great level of success in hand salvage. Conditions such as trauma, tumor, sepsis, or vascular disease, may necessitate hand salvage. The most frequent argument among surgeon from different subspecialties (orthopedics, plastics, trauma, and vascular surgery) are characterized by in what way each one can do his own part of the salvage operation, be it bony fixation, revascularization, or soft-tissue coverage, but none of them is sure whether it should be endeavored. What is necessary in such clinical situations is an interdisciplinary team attitude led by individual or groups of clinicians who are conversant not only with their identifiable subspecialized skills but also with those of their coworkers and the consequences accompanying the joined efforts at hand salvage. The perception of orthoplastic surgery is based on such an indication, where the integrated skills and techniques of the orthopedic surgeon and reconstructive microsurgeon are performed in recital to direct efforts concerning hand salvage or choose against it when it is not designated. The current article reviews the roles of orthopedic and plastic surgery and how this team can deal with the existing techniques to improve outcomes in hand salvage surgery.
