Volar locked plating has become a standard treatment for operative stabilization of distal radius fractures. It is assumed that volar plating portends a low risk of extensor tendon irritation and rupture, especially when compared with dorsal plating constructs; however, extensor tendon tenosynovitis and rupture is a well-described complication after volar plating of the distal radius. Dorsal cortical penetration of screws may go unnoticed with traditional intraoperative fluoroscopic techniques and may contribute to extensor tendon irritation...

Distal radius fractures are among the most common injuries in the upper extremity. While many studies have looked at the maintenance of reduction with volar locking plates, there is a paucity of literature comparing the ability of different plates to maintain reduction over time. This study reviews the ability of various plates to maintain radiographic reduction at union after distal radius fracture treatment. Loss of some aspect of fracture reduction was routinely observed following locked volar plating regardless of implant...

STUDY DESIGN: Single-blinded randomized controlled trial. INTRODUCTION: Pain management is essential in the early stages of the rehabilitation of distal radius fractures (DRFx). Pain intensity at the acute stage is considered important for determining the individual recovery process, given that higher pain intensity and persistent pain duration negatively affect the function and cortical activity of pain response. Graded motor imagery (GMI) and its components are recent pain management strategies, established on a neuroscience basis...

We tested whether cortical bone tissue properties assessed by in vivo impact microindentation would distinguish postmenopausal women with recent distal radius (DRF) or hip fracture (HF) from non-fracture controls (CONT). We enrolled postmenopausal women with recent DRF (n=57), HF (n=41) or CONT (n=93), and used impact microindentation to assess bone material strength index (BMSi) at the anterior surface of the mid-tibia diaphysis. Areal BMD (g/cm(2) ) of the femoral neck (FN), total hip (TH) and lumbar spine (LS) were measured by dual-energy X-ray absorptiometry (DXA)...

Microneedles are micron-sized needles that are widely applied in biomedical fields owing to their painless, minimally invasive, and convenient operation. However, most microneedle fabrication approaches are costly, time consuming, involve multiple steps, and require expensive equipment. In this study, we present a novel magnetorheological drawing lithography (MRDL) method to efficiently fabricate microneedle, bio-inspired microneedle, and molding-free microneedle array. With the assistance of an external magnetic field, the 3D structure of a microneedle can be directly drawn from a droplet of curable magnetorheological fluid...

Flexor tendon injury is a rare, but serious, complication after volar plate fixation for distal radius fractures. The plate position and prominence at the watershed line are contributing factors that cause flexor tendon injury. With the standard volar approach, the pronator quadratus (PQ) is typically elevated off the radial attachment. The distal part of the plate is often visible after repair of the PQ. We describe a "PQ-splitting" technique for covering the distal edge of the plate if primary PQ repair cannot completely cover the distal part of the plate...

Individual trabecular segmentation was utilized to identify differences in trabecular bone structure in premenopausal women with wrist fractures and non-fracture controls. Fracture subjects had reduced trabecular plate volume, number, thickness, and connectivity. Identifying altered trabecular microarchitecture in young women offers opportunities for counseling and lifestyle modifications to reduce fracture risk. INTRODUCTION: Premenopausal women with distal radius fractures (DRF) have worse trabecular bone microarchitecture than non-fracture controls (CONT), yet the characteristics of their trabecular bone structure are unknown...

Upper extremity injuries are associated with significant morbidity in throwing athletes, and prevention and diagnosis of overuse injuries in these athletes are increasingly being emphasized. Although stress fractures are common overuse injuries, stress fractures of the upper extremity are relatively rare. To our knowledge, a stress fracture of the radial shaft has not been reported in a throwing athlete. In this article, we describe the case of a Major League Baseball pitcher who presented with a stress fracture of the lateral cortex of the radius, likely caused by contractile forces of the supinator muscle, arising after his attempt to develop a new pitch...

Distal radius fracture (DRF) is a common injury. Treatment options have evolved and now several can be used to address even the most complex fracture patterns. Complex fractures of the distal radius and ulna can be challenging, and specific goals must be kept in mind to achieve definitive anatomical and functional restoration. This article summarizes the concepts, principles, and surgical options regarding complex DRF reconstruction.

AIM: To evaluate the reliability of pronator quadratus fat pad sign to detect distal radius fracture and to predict its severity. METHODS: Retrospectively we identified 89 consecutive patients (41 female, mean age 49 ± 18 years) who had X-ray (CR) and computed tomography (CT) within 24 h following distal forearm trauma. Thickness of pronator quadratus fat pad complex (PQC) was measured using lateral views (CR) and sagittal reconstructions (CT). Pearson's test was used to determine the correlation of the PQC thickness in CR and CT...
