INTRODUCTION: The incidence of obesity has increased significantly worldwide. Our hypothesis was that patients with obesity have a more severe distal radius fracture andwe realized a study to evaluate this correlation between obesity and severity of distal radius fractures caused by low-energy injuries. MATERIALS AND METHODS: A total of 114 patients with distal radius fracture were examined in a cross-sectional, observational study. Fractures were classified according to the international AO-Müller/Orthopedic Trauma Association (AO/OTA) classification in order to determine the severity...

PURPOSE: To compare the patient-reported, clinical, and radiographic outcome of 2 methods of internal fixation in distal radius fractures. METHODS: Fifty patients, mean age 56 years (range, 21-69 years) with primarily nonreducible or secondarily redisplaced distal radius fractures were randomized to open reduction internal fixation using volar locking plates (n = 25) or fragment-specific fixation (n = 25). The patients were assessed on grip strength, range of motion, patient-reported outcome (Quick Disabilities of the Arm, Shoulder, and Hand), pain (visual analog scale), health-related quality of life (Short Form-12 [SF-12]), and radiographic evaluation...

BACKGROUND: Boys with autism spectrum disorder (ASD) have lower areal bone mineral density (aBMD) than typically developing controls (TDC). Studies of volumetric BMD (vBMD) and bone microarchitecture provide information about fracture risk beyond that provided by aBMD but are currently lacking in ASD. OBJECTIVES: To assess ultradistal radius and distal tibia vBMD, bone microarchitecture and strength estimates in adolescent boys with ASD compared to TDC. DESIGN/METHODS: Cross-sectional study of 34 boys (16 ASD, 18 TDC) that assessed (i) aBMD at the whole body (WB), WB less head (WBLH), hip and spine using dual X-ray absorptiometry (DXA), (ii) vBMD and bone microarchitecture at the ultradistal radius and distal tibia using high-resolution peripheral quantitative CT (HRpQCT), and (iii) bone strength estimates (stiffness and failure load) using micro-finite element analysis (FEA)...

BACKGROUND: Bone mineral content (BMC) and bone mineral density (BMD) are positively correlated with dietary protein intakes, which account for 1-8% of BMC and BMD variances. However, the relation between bone strength and microstructure, which are variables that are not captured by areal bone mineral density (aBMD), and dietary protein intakes, particularly from specific dietary sources, has not been clearly established. OBJECTIVE: We investigated the association between the peripheral skeleton-predicted failure load and stiffness, bone microstructure, and dietary protein intakes from various origins (animal, divided into dairy and nondairy, and vegetable origins) in healthy postmenopausal women...

BACKGROUND: Few studies have assessed bone health in lymphoma survivors treated with high-dose therapy with autologous stem cell transplantation (HDT-ASCT). Therefore, we aimed to assess bone mineral density (BMD) at six different skeletal sites and to investigate associations between clinical factors and BMD in these survivors. MATERIAL AND METHODS: Eligible lymphoma survivors were aged ≥18 years at diagnosis and at HDT-ASCT given between 1987 and 2008. Participants responded to questionnaires, blood samples were drawn, and a dual energy X-ray absorptiometry (DXA) was performed...

Upper extremity fractures in the elderly are very frequent and second only to hip fractures in the group of fragility fractures. Their impact on mobility and functional decline seems to be underestimated especially when they occur in combination with lower extremity fractures. Fractures of the proximal humerus and the distal radius can often be treated conservatively; however, the indications for operative treatment must not be based on fracture morphology alone and due consideration should be given to all concomitant circumstances affecting functional aspects of patients...

Fractures of the distal section of the radius (Colles' fractures) occur earlier in life than other osteoporotic fractures. Therefore, they can be interpreted as a warning signal for later, more deleterious fractures of vertebral bodies or the femoral neck. In the past decade, the advent of HR-pQCT allowed a detailed architectural analysis of the distal radius and an automated but time-consuming estimation of its strength with linear micro-finite element (μFE) analysis. Recently, a second generation of HR-pQCT scanner (XtremeCT II, SCANCO Medical, Switzerland) with a resolution beyond 61 μm became available for even more refined biomechanical investigations in vivo...

BACKGROUND: Our study aimed to investigate whether geometrical features (size, shape, or alignment parameters) of the femoral condyle affect the morphology of the trochlear groove. METHODS: Computed tomography models of 195 femurs (97 and 98 knees from male and female subjects, respectively) were reconstructed into three-dimensional models and categorised into four types of trochlear groove morphology based on the position of the turning point in relation to the mechanical axis (types 45°, 60°, 75°, and 90°)...

BACKGROUND: Previous literature has demonstrated that pediatric orthopaedic patients with private insurance have less difficulty obtaining appointments than those with Medicaid. Not all injuries of an orthopaedic nature, however, require specialist care. This study evaluated the willingness of pediatricians to provide care for minor orthopaedic injuries and whether or not the patient's insurance status influenced the decision to provide care. METHODS: Ninety-nine pediatric primary care offices were randomly selected from 2 regions in Florida...

: This study evaluated the value of computed tomography scans for the diagnosis of distal radioulnar joint instability. A total of 46 patients, conservatively treated for a unilateral distal radius fracture, were evaluated. Clinical instability was tested using the stress test and clunk test. A computed tomography scan of both wrists was performed in pronation and supination. Two independent observers reviewed the computed tomography scans using: the radioulnar line, subluxation ratio, epicentre and radioulnar ratio methods...

Fossorial talpid moles use their limbs predominantly for digging, which explains their highly specialized anatomy. The humerus is particularly short and dorsoventrally rotated, with broadened distal and proximal parts where muscles attach and which facilitate powerful abductive movements. The radius and ulna are exceptionally robust and short. The ulna has an expanded olecranon process. The femur is generalized, but the fused tibia-fibula complex is short and robust. To understand the developmental bases of these specializations, we studied expression patterns of four 5' Hox genes in the fossorial Iberian mole (Talpa occidentalis)...

PURPOSE: To test the biomechanical properties of the dorsoradial capsulodesis procedure. METHODS: Six cadaveric hands were used. After exposing the trapeziometacarpal (TMC) joint, we placed Kirschner wires in the distal radius and thumb metacarpal. The rotation shear test was then performed to test the joint axial laxity, and angular measurements using Kirschner wires as reference points were documented. The dorsoradial (DR) ligament and capsule were released, followed by the intermetacarpal (IM) ligament; angular measurements were obtained...

REVIEW
Julie E Adams
The forearm unit consists of the radius and ulna, a complex and interrelated set of joints (distal radioulnar joint, proximal radioulnar joint) and the soft tissue stabilizers between the 3 bones. Distally, this is represented by the triangular fibrocartilage complex at the wrist, proximally by the annular ligament at the elbow, and in the forearm by the interosseous membrane. Disruptions in any of these structures may lead to forearm instability, with consequences at each of the remaining structures.

The management of upper limb non-unions can be challenging and often with unpredictable outcomes. In this study we present our experience with the use of BMP-7 in the treatment of upper limb non-unions. Between 2004 and 2011 all consecutive patients who were treated with BMP-7 were followed up prospectively until fracture union. Fracture union was assessed with regular radiological and clinical assessment. At the final follow up clinical assessment included the short Disabilities of the Arm, Shoulder and Hand (DASH) score...

INTRODUCTION: Distal radius fracture are common injuries but no gold standard for their therapy exists. The aim of this study was to evaluate the quality of fracture care in distal radius fractures using an intramedullary implant (Targon DR interlocking nail). The nail had been developed to minimize the surgical exposure, increase fixation strength, to prevent tendon irritations and to allow for a fast return to activity. PATIENTS AND METHODS: Prospective study reports the result of 43 patients with an age over 70 years (range 70-91 years) treated by closed reduction and intramedullary fixation...

BACKGROUND: Proposed benefits of intramedullary techniques include limited soft tissue dissection while affording sufficient stability to allow early wrist motion. The primary null hypothesis of this randomized trial was that there is no significant difference with respect to functional outcome, pain and disability between patients treated with either 2.4-mm volar locking plate fixation or intramedullary nail fixation of intra-articular fractures of the distal radius. METHODS: We conducted a single-centre, prospective randomized matched-pairs trial...
