BACKGROUND: Acetabular fractures are quite challenging injuries for the orthopedic surgeon because of their low incidence and their deep and complex anatomy. The objective of this study was to evaluate surgeon-independent parameters that might influence radiographic outcome and early complication rates of high-energy acetabular fractures treated by open reduction and internal fixation via the Kocher-Langenbeck approach, the golden standard for posterior access. METHODS: One hundred sixty-seven consecutive patients (111 males and 56 females) with a mean age of 41...

Recent reports have demonstrated that nearly two-thirds of the world's population do not have access to adequate surgical care, a burden that is borne disproportionately by residents of resource-poor countries. Although the reasons for limited access to surgical care are complex and multi-factorial, among the most substantial barriers is the lack of trained surgical providers. This is particularly true in surgical subspecialties that focus on life-improving, rather than life-saving, treatments, such as pediatric hand and upper extremity surgery, which manages such conditions as congenital malformations, trauma and post-traumatic deformities including burns, and neuromuscular conditions (brachial plexus birth palsy, spinal cord injury, and cerebral palsy)...

Hoverboards burst onto the scene with wide popularity only to be quickly deemed unsafe and banned in many arenas. We conducted a retrospective cohort study of 35 patients seen in our outpatient pediatric orthopedic office over a 1-year period. The mean age of injured patients was 11.14 years; 18 patients were male (51.4%), and 17 were female (48.5%). The highest number of injuries occurred in children 10 to 14 years old who had 57.1% of the injuries. There were a total of 31 fractures in 27 patients. Most of the fractures were in the upper extremities (93...

BACKGROUND AND PURPOSE: T2*-weighted imaging provides sharp contrast between spinal cord GM and WM, allowing their segmentation and cross-sectional area measurement. Injured WM demonstrates T2*WI hyperintensity but requires normalization for quantitative use. We introduce T2*WI WM/GM signal-intensity ratio and compare it against cross-sectional area, the DTI metric fractional anisotropy, and magnetization transfer ratio in degenerative cervical myelopathy. MATERIALS AND METHODS: Fifty-eight patients with degenerative cervical myelopathy and 40 healthy subjects underwent 3T MR imaging, covering C1-C7...

BACKGROUND: Rotator cuff tears are very common and their incidence increases with age. Shoulder ultrasonography has recently gained popularity in detecting rotator cuff tears because of its efficiency, cost-effectiveness, time-saving, and real-time nature of the procedure. Well-trained orthopedic surgeons may utilize shoulder ultrasonography to diagnose rotator cuff tears. The wait time of patients planned to have shoulder MRI (magnetic resonance imaging) to rule in rotator cuff tears may decrease after orthopedic surgeon start doing shoulder ultrasonography as a screening tool for that...

PURPOSE OF REVIEW: This review provides historical background on trauma care in the USA and summarizes contemporary trauma-related health policy issues. It is a primer for orthopedic surgeons who want to promote improvements in research, delivery, and cost reduction in trauma care. RECENT FINDINGS: As of 2010, funding for trauma research accounted for only 0.02% of all National Institutes of Health research funding. This is disproportionate to the societal burden of traumatic injury, which is the leading cause of death and disability among people aged 1 to 46 years in the USA...

Soft supporting tissues in the human body, such as cartilages and ligaments, are tough materials and firmly fixed to bones. These soft tissues, once injured, cannot regenerate spontaneously in vivo. Developing tough and biocompatible hydrogels as artificial soft supporting tissues would substantially improve outcomes after soft tissue injury. Collagen is the main rigid component in soft connective tissues which is organized in various hierarchical arrays. We have successfully developed a novel class of collagen fibril-based tough hydrogels based on the double network (DN) concept using swim bladder collagen (SBC) extracted from Bester sturgeon fish...

INTRODUCTION: Emergency Department (ED) visits for injury often precede hospital admissions in older adults, but risk factors for these admissions are poorly characterized. We sought to determine the incidence and risk factors for hospitalization shortly following discharge home from an ED visit for traumatic injury in older adults. We hypothesized higher risk for admission in those with increased age, discharged home after falls, with increased comorbidity burden, and who live in poor neighborhoods...

Pediatric traumatic brain injury (TBI) research depends on comparisons of profiles and outcome between brain injured individuals and groups consisting either of injured controls (e.g., orthopedic injuries, OI) or uninjured, typically developing children recruited from the community (community controls, CC). Children with OI are thought to provide optimal comparisons for individuals with TBI because they share injury-related experiences and pre-morbid characteristics; however, a study by Mathias and colleagues (2013) in adults has called into question the added value of injury control groups in TBI research...

INTRODUCTION: The damage control orthopedics (DCO) concept is a sequential surgical management strategy indicated when ideal primary treatment is not possible or suitable. DCO principles are routinely applied to hand traumas in wartime practice, but could also be useful in a civilian setting when immediate specialized management cannot be carried out. METHODS: The authors report three typical observations of soldiers treated for a complex hand trauma on the field by orthopedic surgeons from the French Military Health Service (FMHS)...
