Nationwide community based emergency centers reveal scale of hand trauma.

Injury 2022 Jun 10;53(6):2102-2109. Epub 2022 Feb 10.

Braun School of Public Health, Hadassah-Hebrew University, Jerusalem, Israel.

Introduction: This study describes the characteristics of hand trauma treated in community-based emergency centers (CBECs) in Israel. It was hypothesized that the rate of hand trauma, as well as patient and injury characteristics, would differ from a recent study of patients treated in hospital emergency departments (EDs) in Jerusalem.

Methods: Data on all hand injury patients treated at any of the CBECs belonging to a large nationwide chain in 2017 were retrieved from the electronic medical records of the treatment centers, including demographic and clinical characteristics. Read More

Recurrent Convolutional Neural Networks as an Approach to Position-Aware Myoelectric Prosthesis Control.

IEEE Trans Biomed Eng 2022 Jul 17;69(7):2243-2255. Epub 2022 Jun 17.

Objective: Persons with normal arm function can perform complex wrist and hand movements over a wide range of limb positions. However, for those with transradial amputation who use myoelectric prostheses, control across multiple limb positions can be challenging, frustrating, and can increase the likelihood of device abandonment. In response, the goal of this research was to investigate convolutional neural network (RCNN)-based position-aware myoelectric prosthesis control strategies. Read More

Shoulder kinematics plus contextual target information enable control of multiple distal joints of a simulated prosthetic arm and hand.

J Neuroeng Rehabil 2021 01 6;18(1). Epub 2021 Jan 6.

Institut de Neurosciences Cognitives et Intégratives d'Aquitaine, UMR 5287, CNRS and Univ. Bordeaux, 146 rue Léo Saignat, 33076, Bordeaux, France.

Background: Prosthetic restoration of reach and grasp function after a trans-humeral amputation requires control of multiple distal degrees of freedom in elbow, wrist and fingers. However, such a high level of amputation reduces the amount of available myoelectric and kinematic information from the residual limb.

Methods: To overcome these limits, we added contextual information about the target's location and orientation such as can now be extracted from gaze tracking by computer vision tools. Read More

A Muscle Synergy Framework for Cross-Limb Reconstruction of Hand Muscle Activity Distal to a Virtual Wrist-Level Disarticulation.

Annu Int Conf IEEE Eng Med Biol Soc 2020 07;2020:3285-3288

Currently, myoelectric prostheses lack dexterity and ease of control, in part because of inadequate schemes to extract relevant muscle features that can approximate muscle activation patterns that enable individuated dexterous finger motion. This project seeks to apply a novel algorithm pipeline that extracts muscle activation patterns from one limb, as well as from forearm muscles of the opposite limb, to predict muscle activation data of opposite limb intrinsic hand muscles, with the long-range goal of informing dexterous prosthetic control.

Survival and Versatility of the Flow-Through Lateral-Thigh Free Flap in Severe Electrical Injuries to the Wrist.

Ann Plast Surg 2020 12;85(6):612-617

From the Department of Burns and Plastic Surgery, Beijing Jishuitan Hospital, Beijing.

Background: The hand and wrist are most often in contact with electrical currents and thus most vulnerable to severe electrical burns. The treatment of such severe injury via surgical intervention remains a big challenge because of the vast tissue necrosis and the segmental vascular injury. The flow-through lateral-thigh free flap has been used effectively to resurface these defects and to reconstruct segmental vascular defects. Read More

Self-amputation of the Upper Extremity: A Case Report and Review of the Literature.

Cureus 2019 Oct 7;11(10):e5858. Epub 2019 Oct 7.

Plastic and Reconstructive Surgery, University of Texas Health Science Center, Houston, USA.

Indications for upper-extremity replantation include wrist-level and wrist-proximal amputations, due to the devastating loss of function incurred from these severe injuries. Decisions regarding replantation must be made expeditiously at these proximal levels in an effort to minimize ischemia time. This decision-making process becomes more complicated when a patient presents following intentional self-amputation of an extremity, especially in the setting of an associated mood disorder, psychiatric illness, and/or frank psychosis.

Upper extremity myxofibrosarcoma mimicking an erosive inflammatory arthritis: a case report.

Skeletal Radiol 2019 Oct 15;48(10):1643-1649. Epub 2019 Apr 15.

Imaging Institute, Cleveland Clinic, 9500 Euclid Ave. A21, Cleveland, OH, 44195, USA.

Myxofibrosarcoma is a malignant fibroblastic soft tissue neoplasm containing a variable amount of myxoid stroma that commonly presents as a slow-growing mass in elderly patients. The neoplasm may be superficial or deep to the muscle fascia and characteristically has an infiltrative growth pattern with a dominant or multinodular mass. We describe an unusual case of high-grade myxofibrosarcoma of the wrist and forearm that infiltrated the muscles, tendons, and wrist joint, causing bone erosions. Read More

Hand Clin 2019 05;35(2):143-154

Department of Surgery, Division of Plastic and Reconstructive Surgery, University of Colorado, Anschutz Medical Center, 12631 East 17th Avenue, C309 (Room 6414), Aurora, CO 80045, USA; Department of Orthopedics, University of Colorado, Anschutz Medical Center, 12631 East 17th Avenue, C309 (Room 6414), Aurora, CO 80045, USA. Electronic address:

Level of injury plays a significant role in decisions to perform replantation, with improved function, nerve regeneration, and decreased rate of reperfusion injury for injuries at the distal forearm or wrist compared with proximal injuries. The principles of a functional and sensate outcome dictate replantable parts, whereas patient comorbidity, expectations, and safety dictate patient candidacy. Vascular grafts are an expected part of the operation, and the contralateral arm or a lower extremity should be prepped into the surgical field. Read More

Targeted Muscle Reinnervation for Prosthesis Optimization and Neuroma Management in the Setting of Transradial Amputation.

J Hand Surg Am 2019 Jun 4;44(6):525.e1-525.e8. Epub 2019 Feb 4.

Carolinas Medical Center, Atrium Health, Charlotte, NC; Reconstructive Center for Lost Limbs, OrthoCarolina Hand and Wrist Center, Charlotte, NC. Electronic address:

Targeted muscle reinnervation (TMR) is a surgical technique that improves modern myoelectric prosthesis functionality and plays an important role in the prevention and treatment of painful postamputation neuromas. Originally described for transhumeral amputations and shoulder disarticulations, the technique is being adapted for treatment of transtibial, transfemoral, transradial, and partial hand amputees. We describe a new technique for forearm TMR following transradial amputation with an emphasis on selecting nerve transfer patterns, managing sensory nerves, improving terminal soft tissue coverage, and employing pattern recognition technology.

Traumatic Divergent Elbow Dislocation with Associated Forearm Amputation in an Adult: A Case Report.

JBJS Case Connect 2018 Oct-Dec;8(4):e92

Western Orthopaedics, Denver, Colorado.

Case: A 49-year-old right-hand-dominant man sustained an auger-related injury that resulted in open dislocation at the left wrist and palm, with complete amputation of the distal aspect of the forearm and the hand. The injury at the elbow included instability with an ulnar coronoid fracture, posterior dislocation of the ulna, and posterolateral dislocation of the radius. To restore stability of the forearm stump and elbow, we performed a complete resection of the radius, open reduction and internal fixation of the coronoid tip, a repair of the lateral collateral ligament, and transfer of the distal biceps tendon to the coronoid.

Restoring Natural Forearm Rotation in Transradial Osseointegrated Amputees.

IEEE Trans Neural Syst Rehabil Eng 2018 12 13;26(12):2333-2341. Epub 2018 Nov 13.

Osseointegrated transradial prostheses have the potential to preserve the natural range of wrist rotation, which improves the performance of activities of daily living and reduces compensatory movements that potentially lead to secondary health problems over time. This is possible by enabling the radius and the ulna bone to move with respect to each other, restoring the functionality of the original distal-radioulnar joint. In this paper, we report on psychophysics tests performed on an osseointegrated transradial amputee with the aim to understand the extent of mobility of the implants that is required to preserve the natural forearm rotation.
