Hyperimmunoglobulin E syndrome (Job syndrome) discovered in a patient following corrective spine surgery: Case report and review of the literature
Study Design. A case report of the hyperimmunoglobulin E syndrome (Job syndrome) presenting in the context of late postoperative infection after corrective surgery for scoliosis. Objective. To describe the clinical presentation and treatment of a patient with Job syndrome, and its implications for spine surgeons. Summary of Background Data. Job syndrome classically presents with a triad of increased serum immunoglobulin E, multiple abscesses, and pneumonia with pneumatocele formation. In recent years nonimmunologic manifestations have been described, including scoliosis, joint hypermobility, eosinophilia, and atopy. Methods. A 15-year-old female presented with local swelling and fever 2 years after anterior lumbar discectomy and fusion with spinal instrumentation involving T11-L3 levels. Computerized tomography revealed paravertebral, psoas, and pulmonary abscesses. The implants were removed and antibiotic therapy instituted. Further investigation revealed features of the hyperimmunoglobulin E syndrome (Job syndrome). Results. The patient's symptoms resolved, as did markers of inflammation. Conclusions. Job syndrome is a primary immunodeficiency often associated with scoliosis. Given the implications for surgical outcome in immunodeficient patients, the diagnosis should be considered and, blood tests instituted in patients with scoliosis with any of the associated history and physical findings of Job syndrome

The Effect of Comorbidities and Age on Functional Outcomes After Total Knee Arthroplasty in the Octogenarian: A Matched Cohort Study
Introduction: According to the World Health Organization data repository, the average life expectancy at birth for Singapore in 2015 has risen to 83.4 years, and many octogenarians (OG) remain active socioeconomically. The aim of this study is to compare the improvement and the impact of comorbidities on functional recovery after total knee arthroplasty (TKA) between OG and their younger counterparts. Methods: This is a retrospective study of prospectively collected data from a single institution arthroplasty register. Between January 2006 and December 2011, 209 OG with primary knee osteoarthritis underwent TKA. Each OG (mean age 82 ± 2.1) was then carefully matched to a younger control group (YG, mean age 66 ± 4.5). Their postoperative outcomes measured include Oxford Knee Score (OKS), SF36-Physical Function (SF-PF), and knee society rating score comprising of Knee Score (KS) and Function Score (FS). Their respective degrees of improvement were compared and adjusted for their baseline comorbidities, measured using the Deyo-Charlson Comorbidity Index (D-CCI). Results: There were more comorbidities among the OG ( P < .05). Both groups saw the largest improvement ( P < .05) during the first 6 months. There was no statistical significance between their improvement for OKS, KS, and FS between baseline and 6 months and OKS, FS, and SF-PF between 6 and 24 months. Adjusted for D-CCI using linear regression, the above results remained largely unchanged. Discussion: In our study, both groups showed significant improvement across all functional outcomes, especially during the first 6 months. The improvement observed in OG at 6 and 24 months was comparable to that of YG, despite an overall higher baseline D-CCI. Conclusions: Total knee arthroplasty is a viable treatment option for the OG, offering good functional outcomes and results at 6 and 24 months when compared to their younger counterparts
Results, experience and technical points learnt with use of the SKy Bone Expander kyphoplasty system for osteoporotic vertebral compression fractures: a prospective study of 40 patients with a minimum of 12 months of follow-up
To describe our centre’s results, experience and technical points learnt with the SKy Bone Expander System for osteoporotic vertebral compression fractures (VCFs). Forty consecutive patients with painful single level T12 or L1 osteoporotic VCF who had failed conservative management for more than 3 months had 40 single level SKy Bone Expander kyphoplasties performed. Using local anaesthesia with patients in a prone, hyper-lordotic position, a unilateral, percutaneous, intra-pedicular approach was employed. Once correctly positioned, the SKy Bone Expander was expanded, creating a void. It was subsequently contracted, removed and bone cement injected. Pre-kyphoplasty and 12-month post-kyphoplasty radiological and functional outcomes were recorded. Statistical analysis was by Wilcoxon Signed Ranks Test. Median percentage increase in anterior, middle and posterior vertebral body heights at 12-month post-operative was 51.25% [inter-quartile range (IQR) 17.21–93.22], 52.29% (IQR 26.50–126.17) and 9.84% (IQR 4.94–19.26) respectively, while median percentage decrease in kyphotic angle was 30.77% (IQR 17.06–46.61). There was no significant vertebral body correction loss at 12-month post-operative. Visual analogue score, North American Spine Society and Short Form-36 scores for physical functioning and bodily pain scores improved by medians of 5.0 (IQR 3.0–8.0), 1.45 (IQR 0.68–2.90), 20.5 (IQR 0.0–40.8) and 10.0 (IQR 0.0–20.0) respectively. All P-values were <0.001. There were eight adjacent/remote level VCFs, three cases of cement extravasation and one case of the SKy Bone Expander being unable to be contracted and withdrawn from the vertebral body. It was left in situ. This is the first reported incidence of such a complication. The SKy Bone Expander System appears to be a viable alternative to balloon tamp kyphoplasty. Important technical considerations include proper device positioning within the vertebral body before expansion, single use of devices, familiarity with salvage procedure and injection of bone cement under close image intensifier guidance to prevent cement extravasation

Essential Step-by-Step Techniques for Minimally Invasive Spinal Surgery
The ultimate resource for learning and mastering minimally invasive spine surgery techniques An estimated 1.5 million instrumented spinal procedures are performed every year in the US. The majority of decompressions and about 50% of fusion procedures can be performed completely or partially using minimally invasive spine surgery (MISS) techniques. The full potential of MISS techniques has yet to be realized. Essential Step-by-Step Techniques for Minimally Invasive Spinal Surgery by internationally renowned MISS neurosurgeon Roger Härtl, spine-neurosurgeon Rodrigo Navarro-Ramirez, and an impressive group of global multidisciplinary contributors is the most comprehensive and detailed textbook written to date on this topic. The foundation of the book is built on six interacting principles critical to surgical success, and MISS in particular: Target, Technology, Technique, Teaching and Training, Testing, and Talent. The text starts with an opening chapter on the definition of MISS and introduction of these principles. Fifty-six subsequent chapters provide a comprehensive discussion on how to utilize an MISS approach for a full spectrum of spinal pathologies using nuanced variations specific to the operating surgeon. To ensure readers are well versed in all aspects of MISS, these chapters include painstaking details on indications, contraindications, pathoanatomy, operating room set-up, step-by-step techniques, and postoperative management. Key Highlights Contributions from master spine surgeons across the world provide a balanced global perspective on mastering and incorporating diverse techniques into practice Invaluable clinical pearls including tips/tricks and complication avoidance High-quality images, figures, anatomic drawings, and imaging studies illustrate relevant anatomic approaches and corridors and delineate why anatomic masteryis critical to MISS Twenty-five videos enhance the ability to learn and implement MISS approaches This is a must-have resource for practicing spine surgeons interested in MISS who wish to learn the latest techniques from master surgeons and achieve optimal patient outcomes. The text and videos also provide a robust training tool for senior-level orthopaedic and neurosurgery residents and spine fellows
