We treated a patient with a rare combination of ipsilateral fractures of the distal and proximal ends of the radius. A man aged 42 years had simultaneous fractures of the distal and proximal ends of the radius (radial neck) following a roadside accident. The distal end fracture of the radius was treated with surgical reduction and T-plate volar fixation, and the undisplaced radial neck fracture was treated by an above elbow splintage for 2 weeks. The elbow mobilization was started at 2 weeks. The distal radius was protected for another 4 weeks in a below elbow functional brace...

A pediatric patient presenting with an open forearm fracture with segmental defect is rare, and the pediatric orthopedic literature to guide treatment is sparse. There are several described methods to treat the defect, including bone grafting and bone transport techniques. In addition, there are reports of fibular regeneration after resection if the periosteum is left intact. We present a case report of complete regeneration of over half of a pediatric radial shaft with an intact periosteum, after traumatic extrusion from an open fracture...

Robotic exoskeletons can provide the high intensity, long duration targeted therapeutic interventions required for regaining motor function lost as a result of neurological injury. Quantitative measurements by exoskeletons have been proposed as measures of rehabilitative outcomes. Exoskeletons, in contrast to end effector designs, have the potential to provide a direct mapping between human and robot joints. This mapping rests on the assumption that anatomical axes and robot axes are aligned well, and that movement within the exoskeleton is negligible...

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...

Assessing joint position sense for rehabilitation after neurological injury provides a prognostic factor in recovery and long-term functional outcomes. A common method for testing joint position sense involves the active replication of a joint configuration presented via a passive movement. However, recent evidence showed how this sense is mediated by the centrally generated signals of motor command, such that movements produced volitionally may be coded differently from passive movements and accuracy may be different when matching targets presented actively...

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...

Rehabilitation exoskeletons may make use of myoelectric control to restore in patients with significant motor impairment following a spinal cord injury (SCI) a sense of volitional control over their limb - a crucial component for recovery of movement. Little investigation has been done into the feasibility of using surface electromyography (sEMG) as an exoskeleton control interface for SCI patients, whose impairment manifests in a highly variable way across the patient population. We have demonstrated that by using only a small subset of features extracted from eight bipolar electrodes recording on the upper arm and forearm muscles, we can achieve high predictive accuracy for the intended direction of motion...

Background This paper investigates and discusses the effect of perioperative plexus catheter treatment in former CRPS patients. Patients and Methods A retrospective matched-pair analysis was conducted on 10 CRPS patients with comparable injuries, who underwent surgery in the disease-free interval. In 10 cases, the procedure was performed with perioperative plexus catheter treatment (intervention group), whereas 10 patients did not receive perioperative plexus catheter treatment (control group). Results In the intervention group, after a follow-up time of 105 (20-184) days after the last surgical procedure, pain intensity on the visual analogue scale (VAS; 0 to 10) was 6...

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...

BACKGROUND AND OBJECTIVE: Playing string instruments requires advanced motor skills and a long training that is often spent in uncomfortable postures that may lead to injuries or musculoskeletal disorders. Thus, it is interesting to objectively characterize the motor strategy adopted by the players. In this work, we implemented a method for the quantitative analysis of the motor performance of a violin player. METHODS: The proposed protocol takes advantage of an optoelectronic system and some infra-red reflecting markers in order to track player's motion...

BACKGROUND: This study aimed to develop a classification that precisely describes the extensor carpi ulnaris (ECU) groove morphology. METHODS: Reconstructed axial plane computed tomography scans of the wrists of 200 patients were reviewed. Three groups of groove shape were created based on the position of the deepest point: deviated to the ulnar side (Type U), in the middle of the groove (Type M), and deviated to the radial side (Type R). Groove depth, width, carrying angle, and radius of the curvature were measured using the Picture Archiving and Communication System in a slice in which the ulnar head was the largest...

To determine a more precise and reliable method between Greulich-Pyle (GP) and MacKay's (MK) method for the determination of skeletal age in an Indian pediatric population. We carried out a cross sectional study for the assessment of skeletal age on the basis of examination of hand and wrist radiographs of 106 patients (1-15 years of age) who presented with soft tissue injury to hand by the GP and the MK method. These radiographs were evaluated by a radiologist and an orthopedic surgeon independently. In girls, the mean age difference between chronological and skeletal age was 8 months by the GP method, whereas it was 17 months by MK method...

PURPOSE: To correlate the physical examination finding of distal radial metaphyseal tenderness with plain radiographic and magnetic resonance imaging after acute wrist injury to diagnose occult distal radius fractures. We hypothesized that persistent distal radial metaphyseal tenderness 2 weeks after acute injuries is predictive of an occult fracture. METHODS: Twenty-nine adult patients presented, after acute trauma, with distal radial metaphyseal tenderness and initial plain radiographs and/or fluoroscopic images that did not show a distal radius fracture...
