Extra-neural signals from severed nerves enable intrinsic hand movements in transhumeral amputations.

Sci Rep 2022 Jun 17;12(1):10218. Epub 2022 Jun 17.

Center for Bionics and Pain Research, Mölndal, Sweden.

Robotic prostheses controlled by myoelectric signals can restore limited but important hand function in individuals with upper limb amputation. The lack of individual finger control highlights the yet insurmountable gap to fully replacing a biological hand. Implanted electrodes around severed nerves have been used to elicit sensations perceived as arising from the missing limb, but using such extra-neural electrodes to record motor signals that allow for the decoding of phantom movements has remained elusive.

Feasibility of a Wireless Implantable Multi-electrode System for High-bandwidth Prosthetic Interfacing: Animal and Cadaver Study.

Clin Orthop Relat Res 2022 06 23;480(6):1191-1204. Epub 2022 Feb 23.

Clinical Laboratory for Bionic Extremity Reconstruction, Department of Plastic, Reconstructive and Aesthetic Surgery, Medical University of Vienna, Vienna, Austria.

Background: Currently used prosthetic solutions in upper extremity amputation have limited functionality, owing to low information transfer rates of neuromuscular interfacing. Although surgical innovations have expanded the functional potential of the residual limb, available interfaces are inefficacious in translating this potential into improved prosthetic control. There is currently no implantable solution for functional interfacing in extremity amputation which offers long-term stability, high information transfer rates, and is applicable for all levels of limb loss.

Clinical outcome in patients who underwent amputation due to extremity soft tissue sarcoma: Tokai Musculoskeletal Oncology Consortium study.

Jpn J Clin Oncol 2022 Feb;52(2):157-162

Department of Orthopaedic Surgery, Nagoya University Hospital, Nagoya, Japan.

Background: Soft tissue sarcomas are a diverse group of rare malignant tumours, mostly occurring in the lower extremities. Amputations are necessary for achieving local control when the soft tissue sarcomas are too large and/or have neurovascular involvement. Patients who require amputation have a poorer prognosis than those who undergo limb-salvage surgery. Read More

Therapy Interventions for Upper Limb Amputees Undergoing Selective Nerve Transfers.

J Vis Exp 2021 10 29(176). Epub 2021 Oct 29.

Clinical Laboratory for Bionic Extremity Reconstruction, Medical University of Vienna; Department of Plastic and Reconstructive Surgery, Medical University of Vienna;

Targeted Muscle Reinnervation (TMR) improves the biological control interface for myoelectric prostheses after above-elbow amputation. Selective activation of muscle units is made possible by surgically re-routing nerves, yielding a high number of independent myoelectric control signals. However, this intervention requires careful patient selection and specific rehabilitation therapy. Read More

Patterns and Outcomes of High-Voltage vs Low-Voltage Pediatric Electrical Injuries: An 8-Year Retrospective Analysis of a Tertiary-Level Burn Center.

J Burn Care Res 2022 May;43(3):704-709

Department of General Surgery, Burn Center, University of Health Sciences, Adana City Training and Research Hospital, Turkey.

Although electrical injuries (EIs) are rare traumas in the pediatric age group, they are considered one of the most devastating injuries. We aimed to evaluate the patterns and outcomes of pediatric high-voltage injuries (HVIs) vs low-voltage injuries (LVIs), admitted to the burn center within the efforts of determining evidence-based data for contributing to burn prevention strategies. A retrospective study was conducted on children with EIs hospitalized in the Burn Center of Adana City Training and Research Hospital for 8 years (2013-2020). Read More

Decoding attempted phantom hand movements from ipsilateral sensorimotor areas after amputation.

J Neural Eng 2021 09 23;18(5). Epub 2021 Sep 23.

UMC Utrecht Brain Center, Department of Neurology and Neurosurgery, University Medical Center Utrecht, Utrecht, The Netherlands.

The sensorimotor cortex is often selected as target in the development of a Brain-Computer Interface, as activation patterns from this region can be robustly decoded to discriminate between different movements the user executes. Up until recently, such BCIs were primarily based on activity in the contralateral hemisphere, where decoding movements still works even years after denervation. However, there is increasing evidence for a role of the sensorimotor cortex in controlling the ipsilateral body. Read More

Replantation of forequarter amputation: Report of two cases with successful structural, motor and sensorial results.

Microsurgery 2021 Sep 17;41(6):562-568. Epub 2021 Apr 17.

Akdeniz University Faculty of Medicine, Antalya, Turkey.

Although there have been numerous reports of major replantation of upper extremity amputations, limited numbers of above-elbow amputation replantation have been reported. We present the technical details of two successful replantations of forequarter amputations in a nine-year-old girl and a three-year-old boy. In both cases, the forequarter was amputated due to avulsion traction injuries resulting in amputation including the entire upper limb, while the integrity of the scapula and parascapular muscles was maintained, with no injury to the glenohumeral joint.

Revision Targeted Muscle Reinnervation Improves Secondary Pain Insult in an Upper Extremity Amputee: A Case Report.

Hand (N Y) 2021 11 17;16(6):NP15-NP18. Epub 2021 Feb 17.

Medical College of Wisconsin, Milwaukee, USA.

Targeted muscle reinnervation (TMR) has been shown to improve phantom and neuropathic pain in both the acute and chronic amputee population. Through rerouting of major peripheral nerves into a newly denervated muscle, TMR harnesses the plasticity of the brain, helping to revert the sensory cortex back toward the preinsult state, effectively reducing pain. We highlight a unique case of an above-elbow amputee for sarcoma who was initially treated with successful transhumeral TMR. Read More

Outcomes, Challenges, and Pitfalls after Targeted Muscle Reinnervation in High-Level Amputees: Is It Worth the Effort?

Plast Reconstr Surg 2019 12;144(6):1037e-1043e

From the Division of Plastic and Reconstructive Surgery and the Christian Doppler Laboratory for Restoration of Extremity Function, Division of Plastic and Reconstructive Surgery, Department of Surgery, and the Department of Physical Medicine and Rehabilitation, Medical University of Vienna; and the Department of Plastic Surgery, Southmead Hospital, North Bristol NHS Trust.

Background: Although the distal targets have been lost in proximal upper limb amputees, the neural signals for intuitive hand and arm function are still available and thus can be incorporated into more useful prosthetic function using targeted muscle reinnervation technique. In this article, the authors present their outcomes and range of indications in addition to experiences and pitfalls after 30 targeted muscle reinnervation cases at above-elbow and shoulder disarticulation level of amputation.
