PURPOSE: Arthroscopic techniques tend to become the gold standard in rotator cuff repair. However, little data are reported in the literature regarding the improvement of postoperative outcomes and re-tear rate relative to conventional open surgery. The aim of this study was to compare clinical outcomes and cuff integrity after arthroscopic versus open cuff repair. METHODS: We prospectively assessed clinical outcomes and cuff integrity after an arthroscopic or open rotator cuff repair with a minimum follow-up of 12 months...

Two patients-one with a terrible triad fracture dislocation and one with an anterior olecranon fracture dislocation-were treated for maltracking of the elbow (medial subluxation). The radial head articulated with the lateral trochlea while the ulnar trochlear notch was perched over the medial trochlea. The late revision surgery could not correct the subluxation because the joints were accustomed to the new alignment, however the overall function was reasonable.

BACKGROUND: Gender differences may exist for patients undergoing shoulder arthroplasty. Limited data suggest that women may have worse preoperative disability and outcomes. Our objective was to determine whether gender influences preoperative disability and patient-reported outcomes after reverse total shoulder arthroplasty. METHODS: Data were prospectively collected for patients who underwent reverse total shoulder arthroplasty for rotator cuff arthropathy or osteoarthritis with a rotator cuff tear at a single institution between 2009 and 2015...

The ribosome is a large ribonucleoprotein complex that is responsible for the production of proteins in all organisms. Accommodation is the process by which an incoming aminoacyl-transfer RNA (aa-tRNA) molecule binds the ribosomal A site, and its kinetics has been implicated in the accuracy of tRNA selection. In addition to rearrangements in the aa-tRNA molecule, the L11 stalk can undergo large-scale anisotropic motions during translation. To explore the potential impact of this protruding region on the rate of aa-tRNA accommodation, we used molecular dynamics simulations with a simplified model to evaluate the free energy as a function of aa-tRNA position...

BACKGROUND AND PURPOSE: Muscle weakness predisposes older adults to a fourfold increase in functional limitations and has previously been associated with reduced motor cortex excitability in aging adults. The purpose of this study was to determine whether a single session of anodal transcranial direct current stimulation (tDCS) of the motor cortex would increase elbow flexion muscle strength and electromyographic (EMG) amplitude in very old individuals. METHODS: Eleven very old individuals-85...

Lichen amyloidosis (LA) is characterized by the deposition of amyloid that may respond to chronic scratching that may be secondary to atopic dermatitis, stasis dermatitis, or interface dermatitis. Despite the development of several therapeutic strategies, including topical steroids, oral antihistamines, cyclosporine, and retinoids, an effective treatment for LA has not been established. A 49-year-old woman who has been treated irregularly for atopic dermatitis for 7 years presented with localized brownish papules on the left forearm and right elbow...

Previous motor learning studies based on adapting movements of the hemiparetic arm in stroke subjects have not accounted for spasticity occurring in specific joint ranges (spasticity zones), resulting in equivocal conclusions about learning capacity. We compared the ability of participants with stroke to rapidly adapt elbow extension movements to changing external load conditions outside and inside spasticity zones. Participants with stroke (n=12, aged: 57.8±9.6 years) and healthy age-matched controls (n=8, 63...

Water polo is a team sport that combines swimming with overhead throwing and wrestling. This places water polo players at risk for a unique group of illnesses and injuries. In addition to the medical problems and injuries seen in competitive swimmers, water polo players are at risk for a variety of traumatic injuries, including concussions, eye injuries, tympanic membrane perforation, fractures, dislocations, and lacerations. Repetitive overhead throwing also places these athletes at risk for related injuries, such as shoulder problems, including rotator cuff strain and impingement, and elbow problems, such as ulnar collateral ligament injuries, posteromedial impingement, and osteochondritis dissecans of the radial capitellum...

The study was aimed at determining the acute effects of two types of occlusal splints on maximum isometric strength and fatigue of the elbow flexors muscles. The hypothesis was that splint-induced masticatory muscle repositioning might improve primary muscles recruitment by stretching masticatory muscles especially with the thicker splint.On nine physically active volunteers with no temporo-mandibular joint and masticatory muscles disorders, we assessed maximum voluntary contraction (MVC) of the elbow flexors with diurnal (OSD, 1-mm thick) and sport (OSSP, 3-mm thick) splints, and without splint (control, Ctrl)...

Restoration of digital flexion after brachial plexus injury or forearm injury has been a great challenge for hand surgeons. Nerve transfer and forearm donor muscle transfer surgeries are not always feasible. The present study aimed at evaluating the effectiveness of restoring digital flexion by brachialis muscle transfer. Ten lower brachial plexus- or forearm-injured patients were enrolled. After at least 12 months following surgery, the middle-finger-to-palm distance was less than 2.5 cm in six patients...

We previously examined adaptive changes of eye-hand coordination during learning of a visuomotor rotation. Gazes during reaching movements were initially directed to a feedback cursor in early practice, but were gradually shifted toward the target with more practice, indicating an emerging gaze anchoring behavior. This adaptive pattern reflected a functional change of gaze control from exploring the cursor-hand relation to guiding the hand to the task goal. The present study further examined the effects of hemispace and joint coordination associated with target directions on this behavior...

BACKGROUND: Although the transversus abdominis (TrA) is considered to play a significant role in maintaining trunk stability, there is little information regarding the type of exercise that best facilitates the development of tension in the TrA. Muscle elasticity shows a strong association with muscle tension. Shear wave ultrasound elastography provides a means by which the tension of TrA can be noninvasively estimated, by quantifying it's elasticity. PURPOSE: The purpose of this study was to examine the TrA elasticity during several exercises as measured by shear wave ultrasound elastography, and to determine which of the studied exercises demonstrated the greatest tension...

The interaction of body-worn antennas with the human body causes a significant decrease in antenna efficiency and a shift in resonant frequency. A resonant slot in a small conductive box placed on the body has been shown to reduce these effects. The specific absorption rate is less than international health standards for most wearable antennas due to small transmitter power. This paper reports the linear relationship between power absorbed by biological tissues at different locations on the body and radiation efficiency based on numerical modeling (r = 0...
