Bilateral pedicle stress fracture in the lumbar spine of a sedentary office worker

A case of bilateral pedicle fracture in the lumbar spine of a sedentary office worker is being presented. No such case has been reported in the literature previously. Bilateral pedicle fracture is a rare entity. Few cases have been reported in literature. All the reported cases had some underlying causative factors like degenerative spine disease, previous spinal surgery or stress-related activities, e.g. athletes. Our case is a 36-year-old sedentary office worker with none of the factors mentioned. We present a case of a 36-year-old sedentary worker with long-standing low backache. There were no root tension signs. Plain radiographs were inconclusive. The patient had a CT scan. The CT scan revealed long-standing defects in the pedicles of L2 vertebra with pseudoarthrosis. Infiltration with anaesthetic relieved the symptoms. Our patient was managed conservatively with spine rehabilitation physiotherapy program. Pedicle fracture can develop due to abnormal stresses in the pedicle either because of previous spinal surgery or spondylitic changes in the spine. Bilateral pedicle fracture in the absence of these conditions is extremely rare

Adrenal suppression: A practical guide to the screening and management of this under-recognized complication of inhaled corticosteroid therapy

Inhaled corticosteroids (ICSs) are the most effective anti-inflammatory agents available for the treatment of asthma and represent the mainstay of therapy for most patients with the disease. Although these medications are considered safe at low-to-moderate doses, safety concerns with prolonged use of high ICS doses remain; among these concerns is the risk of adrenal suppression (AS). AS is a condition characterized by the inability to produce adequate amounts of the glucocorticoid, cortisol, which is critical during periods of physiological stress. It is a proven, yet under-recognized, complication of most forms of glucocorticoid therapy that can persist for up to 1 year after cessation of corticosteroid treatment. If left unnoticed, AS can lead to significant morbidity and even mortality. More than 60 recent cases of AS have been described in the literature and almost all cases have involved children being treated with ≥500 μg/day of fluticasone

Does soft tissue balancing using intraoperative pressure sensors improve clinical outcomes in total knee arthroplasty? A protocol of a multicentre randomised controlled trial

Introduction Soft tissue imbalance is considered to be a major surgical cause of dissatisfaction following total knee arthroplasty (TKA). Surgeon-determined manual assessment of ligament tension has been shown to be a poor determinant of the true knee balance state. The recent introduction of intraoperative sensors, however, allows surgeons to precisely quantify knee compartment pressures and tibiofemoral kinematics, thereby optimising coronal and sagittal plane soft tissue balance. The primary hypothesis of this study is that achieving knee balance with use of sensors in TKA will improve patient-reported outcomes when compared with manual balancing. Methods and analysis A multicentred, randomised controlled trial will compare patient-reported outcomes in 222 patients undergoing TKA using sensor-guided balancing versus manual balancing. The sensor will be used in both arms for purposes of data collection; however, surgeons will be blinded to the pressure data in patients randomised to manual balancing. The primary outcome will be the change from baseline to 1 year postoperatively in the mean of the four subscales of the Knee Injury and Osteoarthritis Outcome Score (KOOS 4) that are most specific to TKA recovery: pain, symptoms, function and knee-related quality of life. Secondary outcomes will include the surgeon's capacity to determine knee balance, radiographic and functional measures and additional patient-reported outcomes. Normality of data will be assessed, and a Student's t-test and equivalent non-parametric tests will be used to compare differences in means among the two groups. Ethics and dissemination Ethics approval was obtained from South Eastern Sydney Local Health District, Approval (HREC/18/POWH/320). Results of the trial will be presented at orthopaedic surgical meetings and submitted for publication in a peer-reviewed journal. Trial registration number ACTRN#12618000817246
