The overview of the Australian trauma system.

Trauma management in Australia is predominantly that of blunt mechanism trauma spread across a geographically large and sparsely populated country. A complex network of patient care has evolved to manage major trauma. Over recent decades, focus has been given to improving and co-ordinating transfer of patients into major trauma centers and improved data collection with the corresponding improved patient outcomes.

Evidence based management of intracapsular neck of femur fractures.

Neck of femur fractures are occurring at an increased incidence. Functionally independent patients without cognitive impairment can expect reasonable life expectancy. This indicates the need for a durable surgical option that optimises the chance to return to pre-injury functional status, with minimal risk of complications and reoperation.

Comparison of lumbar epidural bupivacaine with fentanyl or clonidine for postoperative analgesia in children with cerebral palsy after single-event multilevel surgery.

Aim: To compare diazepam use, muscle spasm, analgesia, and side effects when clonidine or fentanyl are added to epidural bupivacaine in children with cerebral palsy after multilevel orthopaedic surgery.

Method: Fifty children were prospectively randomized to receive clonidine (n=24, mean age 10y 10mo [SD 2y 11mo]) or fentanyl (n=26, mean age 10y 11mo [SD 2y 10mo]).

Results: There was no difference in primary outcome measures: median diazepam use (fentanyl 0, interquartile range [IQR] 0-0; clonidine 0, IQR 0-0; p=0.

Computational simulation of the early stage of bone healing under different configurations of locking compression plates.

Flexible fixation or the so-called 'biological fixation' has been shown to encourage the formation of fracture callus, leading to better healing outcomes. However, the nature of the relationship between the degree of mechanical stability provided by a flexible fixation and the optimal healing outcomes has not been fully understood. In this study, we have developed a validated quantitative model to predict how cells in fracture callus might respond to change in their mechanical microenvironment due to different configurations of locking compression plate (LCP) in clinical practice, particularly in the early stage of healing.

Can the ICF osteoarthritis core set represent a future clinical tool in measuring functioning in persons with osteoarthritis undergoing hip and knee joint replacement?

Objective: To determine the dimensionality, reliability, model fit, adequacy of the qualifier levels, response patterns across different factors, and targeting of the International Classification of Functioning, Disability and Health (ICF) osteoarthritis core set categories in people with osteoarthritis undergoing hip and knee arthroplasty.

Methods: The osteoarthritis core set was rated in 316 persons with osteoarthritis who were either in the pre-operative or within one year post-operative stage. Rasch analyses were performed using the RUMM 2030 program.

Do patient-reported outcome measures in hip and knee arthroplasty rehabilitation have robust measurement attributes? A systematic review.

Objective: The aim of this study was to systematically review and compare the measurement attributes of multidimensional, patient-reported outcome measures used in hip and knee arthroplasty rehabilitation.

Methods: A search of PubMed, CINAHL, Cochrane Central Registry, SCOPUS and PEDro databases up to December 2009 identified the validation studies. The quality of the measurement properties were assessed based on the Terwee and Bot criteria, and Scientific Advisory Committee of the Medical Outcomes Trust guidelines.

Health-related quality of life outcomes improve after multilevel surgery in ambulatory children with cerebral palsy.

Background: Studies evaluating multilevel surgery to treat spastic deformity and functional deficits in cerebral palsy (CP) usually focus on data from instrumented gait analysis and clinical examination without examining functional and health-related quality of life (HRQOL) outcomes. Recently, outcome measures for well-being in children with a variety of musculoskeletal disorders have also been validated specifically for CP. Therefore, this study aimed to investigate the impact of multilevel surgery on the function and HRQOL in a group of ambulatory children with CP.

Case report: biceps tenosynovial rice bodies.

Here we report the first documented case of rice body formation within the biceps tenosynovium in a patient with juvenile rheumatoid arthritis. We discuss the pathophysiology and the clinical and radiographic findings and correlate these to prior case studies. Lastly, we suggest that limited awareness is a barrier in achieving a timely diagnosis and appropriate management.

Body mass index and Blount disease.

As the increasing prevalence of overweight and obese children is approaching epidemic proportions in North America, this study was designed to investigate whether Body Mass Index (BMI) and age- and gender-specific percentile Body Mass Index (BMI %) are associated with the likelihood of being listed for surgery for Blount disease after initial presentation to a tertiary referral centre. In a restrospective consecutive sample of 102 children with an average age of 5.9 +/- 4.

Total knee arthroplasty: the future.

Few areas in orthopaedics have evolved so dramatically over the past few decades as our knowledge of knee physiology, knee kinematics, and knee replacement surgery. This article addresses major breakthroughs in knee replacement surgery, the thought process behind these concepts, and their impact on clinical practice. It focuses on compartmental arthroplasty, use of minimally invasive surgery, advances in biomaterials, and biological solutions for treating arthritis.

The assessment of acetabular index: is there still a place for plain radiography?

This is a series of 7 children (14 hips) with a mean age of 7.3 years (range, 3.3-10.

Body mass index in patients with slipped capital femoral epiphysis.

Approximately 20% of children with idiopathic slipped capital femoral epiphysis (SCFE) have bilateral disease. Predicting which patients will develop problems with both hips remains difficult. This is the first study to evaluate the relationship between body mass index (BMI) and unilateral and bilateral SCFEs.

Function and well-being in ambulatory children with cerebral palsy.

The purpose of this study was to determine whether there is a significant association between function and well-being in children with cerebral palsy. To determine this, the authors used validated measures of function (Gillette Functional Assessment Questionnaire, Gross Motor Function Classification System, Gross Motor Function Measure, and walking speed) and correlated them to health-related quality of life (HRQOL) measures (Pediatric Outcomes Data Collection Instrument, Pediatric Quality of Life instrument). In a cross-sectional study of ambulatory children with mild to moderate cerebral palsy aged 10.

Calcaneocuboid fusion in children undergoing talectomy.

The aim of management of the child with a severe, rigid equinovarus foot is to provide a foot that is plantigrade and painless and can be placed within standard footwear. The authors identified a retrospective cohort of 17 children with a mean age at surgery of 5.6 years (range 2.

Uptime in children with cerebral palsy.

Quantitative evaluation of function, in children with physical disabilities, has to date been mainly focused on laboratory-based measures. However, the measurement of activity in the community may have a more direct relationship with physical function, health, and well-being. We assessed the utility of a remote activity monitor, the Uptimer (National Aging Research Institute of Melbourne, Melbourne, Australia), to measure one aspect of physical function, time spent in the upright position, in a consecutive cohort of 300 children with cerebral palsy who attended an orthopedic outpatient department.

The Functional Mobility Scale (FMS).

We devised a new Functional Mobility Scale (FMS) to describe functional mobility in children with cerebral palsy, as an aid to communication between orthopaedic surgeons and health professionals. The unique feature of the FMS is the freedom to score functional mobility over three distinct distances, chosen to represent mobility in the home, at school and in the wider community. We examined the construct, content, and concurrent validity of the FMS in a cohort of 310 children with cerebral palsy by comparing the FMS to existing scales and to instrumented measures of physical function.

Primary bacterial pyomyositis associated with septic arthritis caused by Streptococcus pyogenes: a case report.

Pyomyositis is relatively rare in temperate climates. This is the first report of a case of calf pyomyositis associated with septic arthritis of the knee. This case illustrates that pyomyositis should be included in the differential diagnosis of a swollen, tender calf in an emergency setting.

Wound blisters post hip surgery: a prospective trial comparing dressings.

Introduction: Wound blisters are formed in the epidermis adjacent to surgical incisions and are a significant cause of morbidity following hip surgery. This study was designed to compare two commonly used primary dressings, namely a nonadherent absorbable (NAA) dressing and paraffin tulle gras (PTG). Monitoring for the subsequent development of wound blisters in the epidermis adjacent to the surgical incision was then undertaken.
