High-resolution peripheral quantitative computed tomography (HR-pQCT) assesses both volumetric bone mineral density (vBMD) and trabecular and cortical microarchitecture. However, studies of the association of HR-pQCT parameters with fracture history have been small, predominantly limited to postmenopausal women, often performed limited adjustment for potential confounders including for BMD, and infrequently assessed strength or failure measures. We used data from the Osteoporotic Fractures in Men (MrOS) study, a prospective cohort study of community-dwelling men aged ≥65 years, to evaluate the association of distal radius, proximal (diaphyseal) tibia and distal tibia HR-pQCT parameters measured at the Year 14 (Y14) study visit with prior clinical fracture...

The Sauve-Kapandji (SK) procedure for distal radioulnar joint osteoarthritis have complications including pain over the proximal ulnar stump, nonunion of the fused distal radioulnar joint, and less frequently, insufficiency fracture of the distal radius. We report a case of insufficiency fracture of the radial diaphysis as a rare complication of the SK procedure.

INTRODUCTION: The treatment of neglected radial head dislocation after missed Monteggia fracture dislocation in children is a controversial issue. The purpose of this study is to report our clinical experience in the treatment of the condition without annular ligament reconstruction. METHOD: This is a retrospective review of 20 patients between 2008 and 2014. Procedures included open reduction of the radial head and ulnar lengthening angulation osteotomy. In cases of unstable radial head reduction, a trans-capitellar K wire was applied...

Radial head and neck fractures are one of the most common elbow fractures, comprising 2% to 5% of all fractures, and 30% of elbow fractures. Although uncomplicated Mason type I fractures can be managed nonsurgically, Mason type II-IV fractures require additional intervention. Mason type II-III fractures with 3 or fewer fragments are typically treated with open reduction and internal fixation using 2 to 3 lag screws. Transverse radial neck involvement or axial instability with screw-only fixation has historically required the additional use of a mini fragment T-plate or locking proximal radius plate...

Objective: To develop a surgical technique for percutaneous upper extremity fracture fixation using a novel glass-based adhesive. Methods: Three intact upper extremity cadaveric specimens with undisturbed soft tissues were obtained. Two were used to model a wrist fracture, and the third to model a proximal humerus fracture. Fractures were produced using a small osteotome in a percutaneous fashion. Banna Bone Adhesive (BBA) was delivered to the fracture site percutaneously using a 16 gauge needle under bi-planar fluoroscopic guidance...

INTRODUCTION: We report the outcome of using a novel technique of minimally invasive internal fixation and distal radius bone grafting using the Jamishidi Trephine needle and biopsy/graft capture device. METHODS: The technique utilises a 8 mm incision at the distal pole of the scaphoid. The non-union is excavated using the standard Acutrak drill. An 8 gauge Jamshidi trephine needle is used to harvest bone graft from the distal radius which is impacted into the scaphoid and fixed with an Acutrak screw...

A 10-year-old girl presented to the emergency department with proximal radioulnar translocation and radial head fracture, after fall onto an outstretched hand. Open reduction was used to reduce and stabilise the elbow joint after which the radial head was fixated by Kirschner wires. Three months after surgery, full range of motion was regained and union of the radial head was achieved. Proximal radioulnar translocation is a rare injury which is often missed on initial radiographs. Persistent restriction of forearm rotation with seemingly normal elbow configuration must trigger to take a closer look at the relationship between the ulna, radius and distal humerus...

Flexor tendon injury after volar plating of distal radius fractures is due to friction against the plate. To assess this risk, the distance between the flexor pollicis longus (FPL) and the volar prominence of the plate was measured with ultrasonography under various conditions: a standard plate fixed proximal or distal to the watershed line and a low-profile volar rim plate, with and without transection of the pronator quadratus (PQ). Distance from the FPL to the volar prominence of the plate decreased significantly when the PQ was cut and when a standard plate was placed distal to the watershed line, with the tendon often bulging over the plate...

AIM: To determine if ketamine sedation is a safe and cost effective way of treating displaced paediatric radial and ulna fractures in the emergency department. METHODS: Following an agreed interdepartmental protocol, fractures of the radius and ulna (moderately to severely displaced) in children between the age of 2 and 16 years old, presenting within a specified 4 mo period, were manipulated in our paediatric emergency department. Verbal and written consent was obtained prior to procedural sedation to ensure parents were informed and satisfied to have ketamine...

PURPOSE: To determine the accuracy of a distal-first open reduction internal plate fixation technique in achieving correction of volar tilt in dorsally angulated distal radius fractures. METHODS: Twenty foam radius models were divided evenly into groups N (normal) and O (osteoporotic). Dorsally angulated extra-articular distal radius fractures were then created. Group O underwent further modification to simulate an osteoporotic model. After static pinning in various degrees of dorsal angulation, opaque fiducial markers were placed and fluoroscopy was used to measure prereduction volar tilt...

Background: There is evidence that human immunodeficiency virus (HIV) infection and antiretroviral therapy (ART) are independent risk factors for osteoporosis and fracture which is not solely explained by changes in bone mineral density. Thus, we hypothesized that the assessment of trabecular microstructure might play an important role for bone quality in this population and might explain the increased fracture risk. In this study, we have assessed bone microstructure in the proximal femur using high-resolution magnetic resonance imaging (MRI) as well as in the extremities using high resolution peripheral quantitative computed tomography (HR-pQCT) in HIV-infected men and healthy controls and compared these findings to those based on areal bone mineral density (aBMD) derived from dual X-ray absorptiometry (DXA) which is the standard clinical parameter for the diagnosis of osteoporosis...

PURPOSE: To present a new arthroscopic method for treating supination losses. METHODS: Six patients (15-71 y) were eligible for this study. All had a history of trauma to the wrist more than 6 months previously. Five of them had sustained a distal radius fracture: 3 had been treated with a volar plate (1 of them for an extra-articular malunion), 1 with an external fixator and K-wires, and 1 had been treated in a cast. One of these patients underwent a further operation for correcting an intra-articular malunion...

BACKGROUND: The association of scaphoid or other carpal bone fractures with distal radius fractures is frequently reported, whereas few studies have described pisiform malalignment associated with distal radius fractures. The purpose of this study was to investigate the frequency and characteristics of pisiform malalignment associated with distal radius fractures. METHODS: We performed a retrospective study by reviewing the data of 152 consecutive patients with a mean age of 63 years who were treated surgically for distal radius fractures during a five-year period...

Radial shaft convergence in distal radius fractures is often misdiagnosed. This common deformation is often associated with a radial translation of the distal fragment. This parameter has to be corrected because of the increased risk of distal radioulnar joint instability due to detensioning of the distal interosseous membrane if there is an associated triangular fibrocartilage complex lesion. A new radiologic sign for diagnosis of proximal radius convergence during distal radius fracture is presented as well as technical tips for correction of this deformity...

The minimally invasive flexor carpi radialis approach can be used for volar locking plate fixation of distal radius fractures. After 15-mm incision on the lateral aspect of the FCR tendon and all structures but the radial artery are reclined ulnarly, a plate is inserted under the pronator quadratus just proximal to the "watershed line." The distal epiphyseal screws are put in place, and the proximal part of the plate is exposed by flexion of the wrist to put in place the proximal screws. No drainage or postoperative immobilization is used...

BACKGROUND: Vascularized periosteal flaps from the distal radius have been previously proposed. The purpose of this study was to investigate the vascularity and osteogenic potential of a vascularized volar distal radial periosteal flap for the treatment of scaphoid nonunion. METHODS: In 5 fresh frozen cadavers, a rectangular periosteal flap was elevated from the distal radius with the pedicle just proximal to the watershed line. Latex dye was injected into the radial artery proximally and the vascularity of the flap characterized by microscopic evaluation...

BACKGROUND: The aim of this study was to compare the complete visible surface area of the radial head, neck, and coronoid in the Kaplan and Kocher approaches to the lateral elbow. The hypothesis was that the Kaplan approach would afford greater visibility due to the differential anatomy of the intermuscular planes. METHODS: Ten cadavers were dissected with the Kaplan and Kocher approaches, and the visible surface area was measured in situ using a 3-dimensional digitizer...

INTRODUCTION: In 2015, 11.9% of people with cystic fibrosis (CF) in the United States had osteopenia, 5.1% osteoporosis, and 0.3% experienced a fracture. Screening for CF-related bone disease starts in childhood, and dual energy x-ray absorptiometry (DXA) is the recommended method. It is unknown whether peripheral quantitative computed tomography (pQCT) can detect deficits earlier than DXA. This study compared pQCT and DXA scans in a group of pre-pubertal children with CF and healthy controls...

Fractures are common traumatic injuries that mainly occur in the metaphyses of long bones such as the proximal humerus, distal radius, and proximal femur. However, most studies of fracture repair processes have focused on the diaphyseal region. In this study, we compared the bone repair processes of the metaphysis and the diaphysis of the mouse tibia. Bone apertures were formed in the tibial metaphysis and diaphysis. At indicated times after surgery, samples were collected, and the healing process was investigated using micro-computed tomography, as well as histological, immunohistochemical, and mRNA expression analyses...
