Ying Yang, Qudong Yin, Dongchen Li, Yongjun Rui, Yongwei Wu, Yanping Ding, Yan Jiang
BACKGROUND: Intermediate column fractures of the distal radius (ICF) are fractures only or mainly limited to the lunate fossa of the distal radius. There are no classification systems and its value evaluation for ICF in the literature. METHODS: According to the characteristics of ICF, ICF were divided into the volar, dorsal, split, collapse, and collapse with split types. Inter- and intra-observer agreements were analyzed with kappa statistics. Seventy-four patients with ICF were retrospectively studied from January 2008 to June 2016...

Scaphoid non-union management is still a challenge in clinical practice for orthopaedic surgeons. Though several treatment methods have been described, there is an ongoing debate about optimum management. Based on new concepts about avascular conditions, promising results were reported with metaphyseal decompression of the distal radius by increasing the vascularization of the radial column of the carpus. We aimed to evaluate the clinical, radiological, and functional outcomes of distal radius core decompression and fixation with palmar percutaneous cannulated compression screws without grafting in patients with scaphoid waist fracture non-union...

Osteoporosis is associated with increased risk of fractures, which is clinically defined by low bone mineral density. Increasing evidence suggests that trabecular bone (TB) micro-architecture is an important determinant of bone strength and fracture risk. We present an improved volumetric topological analysis algorithm based on fuzzy skeletonization, results of its application on in vivo MR imaging, and compare its performance with digital topological analysis. The new VTA method eliminates data loss in the binarization step and yields accurate and robust measures of local plate-width for individual trabeculae, which allows classification of TB structures on the continuum between perfect plates and rods...

INTRODUCTION: For intra-articular distal radius fractures (AO Classification, type B2) with a displaced dorsal fragment, there remains much discussion on the fixation method for the dorsal fragment. To reduce the displaced dorsal fragment, we developed a new technique consisting of fenestration of the volar bone cortex, reduction using an intramedullary procedure, and fixation using a volar plate. This avoids necessity of dorsal approach. TECHNICAL NOTE: We performed this surgical technique in 2 patients and achieved a good reduced position without much injury to the bone cortex at the site of volar plate placement...

BACKGROUND: Management of distal radius fractures (DRFs) is still controversial and may be influenced by the initial fracture classification. Even though numerous classification systems have been proposed in this regard, the evaluation and management of this fracture has remained problematic. OBJECTIVES: The purpose of this study was to evaluate the functional outcome of DRF managed on the basis of a new classification. This classification named as Barzullah Working Classification represents a modification of Melone classification, which is based on fracture stability...

BACKGROUND: No single epidemiological study of upper extremity fractures exists in the United States using data from all payers. Current epidemiological estimates are based on case series, foreign databases, or Medicare data, which are not representative of the entire US population. The objective of this project was to accurately describe the incidence of fractures of the upper extremity in a representative sample of the US population. METHODS: Using International Classification of Disease, Ninth Edition codes for patient visits reported in the 2009 State Emergency Department Database and the State Inpatient Database, available from the Healthcare Cost and Utilization Project, and 2010 US Census data, we calculated the annual incidence rates per 10,000 persons of upper extremity fractures of all patients, regardless of age or payer type...

INTRODUCTION: The most commonly used classification for pediatric physeal fractures has been proposed by Salter and Harris. Among the most suitable classification schemes are those proposed by Ogden and Peterson who added several new types of injuries. The purpose of this study was to examine the value of both schemes to classify all different types of physeal injuries of the distal radius that are not included in the Salter-Harris system and to test a new nomenclature to classify and guide treatment for the whole spectrum of these injuries...

BACKGROUND: Implants based on the polyetheretherketon (PEEK) polymer have been developed in the last decade as an alternative to conventional metallic devices. PEEK devices may provide several advantages over the use of conventional orthopedic materials, including the lack of metal allergies, radiolucency, low artifacts on magnetic resonance imaging scans and the possibility of tailoring mechanical properties. The purpose of this study was to evaluate the clinical results at 12-month follow-up using a new plate made of carbon-fiber-reinforced polyetheretherketon for the treatment of distal radius fractures...

PURPOSE OF THE STUDY: Abraham Colles classified and described fractures of the distal epiphyseal radius. He recommended the arm should be immobilized in a cast that extends from the base of the fingers to above the elbow, while holding this joint at ninety degrees of flexion the forearm in pronation and the wrist in slight flexion and ulnar deviation. We identified the brachioradialis muscle as the main culprit in the frequently observed loss of reduction of the fracture. Since the brachioradialis is attached to the distal region of the radius and functions as a flexor of the elbow when the forearm is in pronation, its stimulation easily displaces a reduced fracture, particularly if its geometry suggests axial instability...

We analyzed the efficiency of a new plate DiPhos-RM in CFR-PEEK [carbon-fiber-reinforced poly (etheretherketone)] for the volar fixation of distal radius fractures. The new plate's composition has the advantage of x-ray absolute transparency, therefore allowing to monitor the healing of the fracture. The desired combination of high strength and low rigidity is obtained through the use of the polymer composites CFR-PEEK. In this preliminary study (from March 2012 to June 2012), 10 cases of intra-articular distal radius fractures were treated with DiPhos-RM produced by Lima Corporate (Italy)...

The Henry approach is the classical anterolateral surgical exposure of the volar aspect of the distal radius. This approach does not allow good access to the medial side of the volar distal radius (lunate facet) and the distal radio-ulnar joint, unless it is extended proximally, retracting the tendons and the median nerve medially, which can cause some trauma. The purpose of our study was to investigate the anatomic basis and to outline the advantages of the unusual anteromedial approach, reporting our experience in the treatment of 4 distal radius fractures, with a 90° or 180° twist of the lunate facet, and 10 wrist dissections on cadavers...

Although the Korean population does not have high risk for osteoporosis, the numbers of osteoporosis-related fractures represent a considerable economic burden to society. The purpose of this study was to determine the incidence and residual lifetime risk of osteoporosis-related fractures in Korea, using data from the Health Insurance Review and Assessment Service (HIRA), which includes nationwide information compiled by the Korean government. All new visits or admissions to Korean clinics or hospitals for fractures were recorded prospectively in a nationwide cohort by the Korean HIRA using the International Classification of Diseases, 10th revision, codes and procedure codes...

UNLABELLED: The purpose of this study was to assess changes in epidemiology and reasons for wintertime excess of distal radius fractures in Oulu, Finland. Our results showed that age-specific incidence of distal radius fractures in elderly women in Finland has increased compared with a previous study. Slippery pavement surfaces assessed by a new meteorological model partly explained wintertime excess of fractures, but factors beyond weather are contributing to seasonality. INTRODUCTION: In this report, we describe the epidemiology and seasonal variation of distal radius fractures in Oulu, Finland, with a focus on the effect of weather and slippery pavement conditions...

Distal radius fracture is one of the most common injuries of human beings, particularly in young males and elderly females. There are various classifications among which classification by author' names and the AO fracture classification system are most frequently used. Although the latter one is overall and consummate, a precise classification system with complete description of the fracture remains to be raised. Recently, with the development of wrist biomechanics and microscope anatomy, more and more studies were made to treat distal radius fracture...

Trabecular bone (TB) is a complex quasi-random network of interconnected plates and rods. TB constantly remodels to adapt to the stresses to which it is subjected (Wolff's Law). In osteoporosis, this dynamic equilibrium between bone formation and resorption is perturbed, leading to bone loss and structural deterioration. Both bone loss and structural deterioration increase fracture risk. Bone's mechanical behavior can only be partially explained by variations in bone mineral density, which led to the notion of bone structural quality...
