    Volar locking plates are an increasingly popular treatment for distal radius fractures. We reviewed complications observed after volar locking plate fixation in a busy teaching hospital. The purpose of the study was to assess whether complication rates after volar locking plate use in general, routine trauma practice were higher than published literature from expert users. A retrospective review was carried out of patients treated with a volar locking plate between January 2009 and ...

    Fractures of the odontoid peg are common spinal injuries in the elderly. This study compares the survivorship of a cohort of elderly patients with an isolated fracture of the odontoid peg versus that of patients who have sustained a fracture of the hip or wrist. A six-year retrospective analysis was performed on all patients aged > 65 years who were admitted to our spinal unit with an isolated fracture of the odontoid peg. A Kaplan-Meier table was used to analyse survivorship from the ...

    BACKGROUND: Hip and wrist fractures are the most common orthopaedic injuries. Combined hip and distal radius fractures are an important clinical and public health problem, since mobilisation and rehabilitation is challenging and likely to be prolonged in this setting. Few studies have explored the influence of an associated wrist fracture in patients with hip fracture. We present the largest series of patients with concomitant hip and wrist fractures. We perform the first meta-analysis ...

    AIMS: This purpose of this meta analysis was to investigate and quantify the relative risk of hip fracture in patients who have sustained a wrist fracture.

    METHOD: Studies were identified by searching Medline, Embase, Cochrane CENTRAL database and CINAHL from their inception to August 2015. Studies reporting confirmed hip fracture following wrist fracture were included. Data extraction was carried out using a modified Cochrane data collection form by two reviewers independently. Quality ...

    AIMS: The degree of displacement of a fracture of the distal radius is an important factor which can be assessed using simple radiographic measurements. Our aim was to investigate the reliability and reproducibility of these measurements and to determine if they should be used clinically.

    PATIENTS AND METHODS: A 10% sample was randomly generated from 3670 consecutive adult patients who had presented to University Hospitals of Leicester NHS Trust between 2007 and 2010 with a fracture of ...

    AIMS: Carpal malalignment after a distal radial fracture occurs due to loss of volar tilt. Several studies have shown that this has an adverse influence on function. We aimed to investigate the magnitude of dorsal tilt that leads to carpal malalignment, whether reduction of dorsal tilt will correct carpal malalignment, and which measure of carpal malalignment is the most useful.

    METHODS: Radiographs of patients with a distal radial fracture were prospectively collected and reviewed. ...

    This study investigated the accuracy and maintenance of reduction of intra-articular steps achieved with closed reduction and percutaneous K wires and open reduction and a volar locking plate for the treatment of intra-articular distal radius fractures. We performed a retrospective review of 359 patients with an intra-articular fracture of their distal radius. Multivariate linear regression was undertaken to investigate the influence of multiple variables such as age, gender, initial ...

    INTRODUCTION Intramedullary nailing is a common treatment for proximal femoral fractures. Fracture of the nail is a rare but devastating complication that exposes often frail patients to complex revision surgery. We investigated which risk factors predict nail failure. METHODS We reviewed all cases of nail breakage seen over a 10-year period in a single busy trauma unit; 22 nail fractures were seen in 19 patients. Comparison was made with a group of 209 consecutive patients who underwent ...

    Distal radial fractures are the most common adult orthopaedic fracture. We sought to determine whether the incidence of this injury is changing and identify trends in its occurrence. We analysed data for all adult patients presenting to University Hospitals of Leicester with a distal radial fracture from 2007-2016. Incidence rates were calculated using United Kingdom population data. Poisson regression techniques were used to analyse weekly, seasonal and annual variation in fracture ...

    The ageing population and an increase in both the incidence and prevalence of cancer pose a healthcare challenge, some of which is borne by the orthopaedic community in the form of osteoporotic fractures and metastatic bone disease. In recent years there has been an increasing understanding of the pathways involved in bone metabolism relevant to osteoporosis and metastases in bone. Newer therapies may aid the management of these problems. One group of drugs, the antibody mediated ...

    INTRODUCTION: This observational study investigated the incidence of distal radius fractures in children, to determine whether the rate is rising, the effect of seasonal variation on incidence and whether fracture type and rate of surgical intervention has changed, to help in determining costs for secondary care and to aid resource allocation.

    MATERIALS AND METHODS: All paediatric patients(n = 6529) who sustained a distal radius fracture over an eight-year period (2007-2014) were ...

    Aims: The aim of this study was to evaluate the need for hand trauma services during the COVID-19 pandemic lockdown, specifically related to surgical requirements. This will provide useful information for planning and resource allocation in the event of any further lockdown.

    Methods: A prospective analsysis of all patients attending our hand trauma unit throughout the UK COVID-19 lockdown period (24 March to 10 May 2020) was carried out. Prospectively collected departmental data from the ...

    Distal radius fractures are very common yet controversy exists regarding which require treatment and is reflected by significant variation in surgical intervention rate. Evidence regarding which fractures would benefit from intervention is varied and largely poor quality. This study had three aims; identify which radiographic parameters are clinically important; quantify the threshold of displacement at which intervention should occur and investigate which patient factors influence the ...

    Introduction Fractures of the distal radius are the most common fracture in humans and are the sempiternal hazard of 3.5 million years of bipedalism. Despite the antiquity of the injury, one of the most controversial topics in current orthopaedics is the management of distal radius fractures. It has been suggested that radiographic appearances rarely correlate with functional outcomes. As the success of the human species is predicated almost exclusively on its dexterity and intelligence, ...

    INTRODUCTION: Predicting when fracture incidence will rise assists in healthcare planning and delivery of preventative strategies. The aim of this study was to investigate the relationship between temperature and the incidence of hip and wrist fractures.

    METHODS: Data for adults presenting to our unit with a hip or wrist fracture over a seven and eight-year period respectively were analysed. Incidence rates were calculated and compared with meteorological records. A Poisson regression ...
