The purpose of this study was to assess the long-term outcomes of radioscapholunate fusion, with and without distal pole of scaphoid excision and excision of the triquetrum. These compromised three operative groups. Seventeen patients were identified with a minimum of 10 years follow-up, with a mean of 15 years (range 10-19). Fifteen of the 17 patients were satisfied with their outcome. Two were converted to total wrist fusion. The mean outcomes scores were; pain visual analogue scale score 2.1/10, Quick Disabilities of the Arm, Shoulder, and Hand 29 and Modified Mayo Wrist score 60...

BACKGROUND: In 2001, the European League Against Rheumatism developed and disseminated the first guidelines for musculoskeletal (MS) ultrasound (US) in rheumatology. Fifteen years later, the dramatic expansion of new data on MSUS in the literature coupled with technological developments in US imaging has necessitated an update of these guidelines. OBJECTIVES: To update the existing MSUS guidelines in rheumatology as well as to extend their scope to other anatomic structures relevant for rheumatology...

BACKGROUND: Distal radius and ankle fractures are one of the most common operatively treated fractures. To date, there is no consensus concerning the need for a standard postoperative radiograph. This leads to undesirable practice variations. A standardized radiograph in the department of radiology would theoretically be more reproducible and operator independent than an intraoperatively obtained fluoroscopic image. However, if adequate intraoperative radiographs have been obtained, it is questionable if these postoperative radiographs are necessary and will lead to changes in the treatment strategy...

Prosthetic arms should restore and extend the capabilities of someone with an amputation. They should move naturally and be able to perform elegant, coordinated movements that approximate those of a biological arm. Despite these objectives, the control of modern-day prostheses is often nonintuitive and taxing. Existing devices and control approaches do not yet give users the ability to effect highly synergistic movements during their daily-life control of a prosthetic device. As a step towards improving the control of prosthetic arms and hands, we introduce an intuitive approach to training a prosthetic control system that helps a user achieve hard-to-engineer control behaviours...

Myocontrol, that is control of prostheses using bodily signals, has proved in the decades to be a surprisingly hard problem for the scientific community of assistive and rehabilitation robotics. In particular, traditional surface electromyography (sEMG) seems to be no longer enough to guarantee dexterity (i.e., control over several degrees of freedom) and, most importantly, reliability. Multi-modal myocontrol is concerned with the idea of using novel signal gathering techniques as a replacement of, or alongside, sEMG, to provide high-density and diverse signals to improve dexterity and make the control more reliable...

This paper presents the development of wrist ROM measurement system that was implemented on a rehabilitation glove for paretic hand, Easy-Flex, using a rotary potentiometer. This approach enables the device to measure the angles of up to 80° with the approximate resolution of 0.1°. The method along with a universal goniometer and a smartphone clinometer application were tested on 17 healthy participants in terms of reliability. The three instruments were able to accurately measure three different angles (flexion: -10°, neutral: 0°, and extension: 20°) with measurement errors less than 2(°)...

State of art upper limb prostheses lack several degrees of freedom (DoF) and force the individuals to compensate for them by changing the motions of their arms and body. Such movements often yield to articulation injuries, nonetheless these could be prevented by adding DoFs, for instance, an articulated passive wrist. Available stiff or compliant wrists with passive flexion/extension and/or radial/ulnar deviation are sub-optimal solutions. Indeed, stiff wrists induce the individuals wearing them to perform exaggerated compensatory movements during the reaching phase while compliant wrists proved to be unpractical while manipulating heavy objects...

Robotic devices have been clinically verified for use in long duration and high intensity rehabilitation needed for motor recovery after neurological injury. Targeted and coordinated hand and wrist therapy, often overlooked in rehabilitation robotics, is required to regain the ability to perform activities of daily living. To this end, a new coupled hand-wrist exoskeleton has been designed. This paper details the design of the wrist module and several human-related considerations made to maximize its potential as a coordinated hand-wrist device...

The purpose of this research is to propose a design of a clinically relevant upper-limb (hand, wrist, and elbow) exoskeleton that meets the clinical requirements. At first, the proposed robot was designed to have sufficient torque for passive exercise therapy and spasticity measurement of post-stroke patients with spasticity (grade 3 or lower in Modified Ashworth Scale). Because the therapy of patients with high level spasticity could be laborious for therapists by increased muscle tone, and the patients tend not to get enough rehabilitation treatment...

OBJECTIVE: Analysis of various parameters related to the patient, the disease, and the needed surgical maneuvers to develop guidance for preoperative selection of the appropriate and the best approach for a given patient. Rapid advances in minimally invasive surgical technology are fascinating and challenging alike. It can be difficult for surgeons to keep up with new modalities that come on to the market place and to assess their true value, i.e., distinguish between fashionable trends versus scientific evidence...

INTRODUCTION: This case study describes the application of a commercially available, custom myoelectric elbow-wrist-hand orthosis (MEWHO), on a veteran diagnosed with chronic stroke with residual left hemiparesis. The MEWHO provides powered active assistance for elbow flexion/extension and 3 jaw chuck grip. It is a noninvasive orthosis that is driven by the user's electromyographic signal. Experience with the MEWHO and associated outcomes are reported. MATERIALS AND METHODS: The participant completed 21 outpatient occupational therapy sessions that incorporated the use of a custom MEWHO without grasp capability into traditional occupational therapy interventions...

BACKGROUND/PURPOSE: Radial head replacement is frequently used in treatment of radial head fractures or sequela. Impossibility to restore a correct anatomy, acute elbow traumatic instability and failure of osteosynthesis hardware are the most common indications. The authors describe their case studies and results on the implantation of various radial head prostheses. MATERIALS: Between June 2005 and June 2016, 28 radial head prostheses were implanted in the same number of patients with an average follow-up of 49 months (6-104)...

Scapholunate dissociation in stages 2 and 3 may lead to posttraumatic damage if left untreated. Different types of treatment have been described, including capsulodesis, tenodesis, and others. The purpose of all procedures is to avoid palmar shift of the distal scaphoid resulting in secondary arthritis (SLAC wrist). This study aimed to evaluate a modified dorsal ligamentoplasty in second- and third-degree scapholunate dissociation in a prospective study design. Furthermore, the study aimed to find out if there is a correlation between radiological and clinical parameters at follow-up and whether or not a SLAC wrist can be avoided...

Background High-pressure injection injuries are devastating injuries that often lead to an amputation of the primarily affected finger. The available literature mainly focuses on amputation rates, while there is a lack of knowledge regarding functional results. Patients and Methods Between 1998 and 2016, 47 cases of high-pressure injection injuries of the hand were registered in our department. Out of these, data of 26 patients, all men with an average age of 42 (18-62) years, were included in a retrospective follow-up examination after 4 (1-12) years...

Ronald A Bos, Dick H Plettenburg
The addition of a cosmetic glove to an upper limb prosthesis has a distinct effect on the cosmetic value, but its viscoelastic behaviour adds a substantial amount of stiffness and hysteresis to the system. As a result, the overall usability of the prosthesis is degraded. A novel negative stiffness element is designed to compensate for the cosmetic glove's stiffness. A combination of linear helical springs and the concept of rolling link mechanisms has resulted in a Rolling Stiffness Compensation Mechanism (RSCM)...

S J Wilkinson, A Naylor, K L Goh
This paper describes a simple protocol for measuring the joint space of the rheumatoid arthritic (RA) wrist from projection radiographs. The protocol is implemented using a computer algorithm based upon the Interactive Data Language platform. The computerized algorithm features a user-friendly graphical interface to aid the operator to measure joint space parameters, namely distance and area, of the wrist vertebral morphometry at the radiocarpal region. Dual-energy X-ray absorptiometry (DXA) radiograph of a standard hand and wrist phantom was evaluated using the measurement protocol to determine the accuracy and precision of the protocol...

BACKGROUND: BoneXpert is an automated method to calculate bone maturation and bone health index (BHI) in children with juvenile idiopathic arthritis (JIA). Cartilage thickness can also be seen as an indicator for bone health and arthritis damage. The objective of this study was to evaluate the relation between cartilage thickness, bone maturation and bone health in patients with JIA. METHODS: Patients with JIA diagnosed according ILAR criteria included in a previous ultrasonography (US) study were eligible if hand radiographs were taken at the same time as the US examination...
