BACKGROUND: A long-standing relationship between orthopaedic surgeons and industry has made financial conflicts of interest a concerning issue. Research supports that financial conflicts of interest can influence both medical research and clinical practice. Financial conflicts of interest may also influence clinical practice guideline recommendations and their corresponding appropriate use criteria. Because of the influential nature of these guidelines, it is imperative that care be taken to minimize bias during guideline development...

BACKGROUND: Potential sex bias has been shown in general surgery basic science and translational research, with unequal representation of male and female specimens. Because basic science research forms the foundation for clinical studies on which patient care is based, it is important that this research equally consider both sexes. The purpose of this study was to determine if potential sex bias exists in the basic science and translational orthopaedic literature. METHODS: A systematic review was conducted of all articles published in 2014 in The Journal of Bone & Joint Surgery, Clinical Orthopaedics and Related Research, The Bone & Joint Journal, and the Journal of Orthopaedic Research (JOR)...

BACKGROUND: The effect of alternative bearing materials on the risk of revision due to infection after total knee replacement remains uncertain. By reducing the immunomodulating polyethylene wear-particle burden and with different substrate bacterial adhesion properties, Oxinium oxidized zirconium and cross-linked polyethylene (XLPE) could alter infection risk. The purpose of the current study was to analyze the risk of revision for infection in 3 comparisons of bearing combinations. METHODS: To evaluate the risk of revision for infection with XLPE, cobalt-chromium (CoCr) on XLPE was compared with CoCr on non-cross-linked polyethylene (NXLPE)...

Platelet-derived biomaterials are widely explored as cost-effective sources of therapeutic factors, holding a strong potential for endogenous regenerative medicine. Particularly for tendon repair, treatment approaches that shift the injury environment are explored to accelerate tendon regeneration. Herein, genipin-crosslinked platelet lysate (PL) patches are proposed for the delivery of human-derived therapeutic factors in patch augmentation strategies aiming at tendon repair. Developed PL patches exhibited a controlled release profile of PL proteins, including bFGF and PDGF-BB...

BACKGROUND: Although gunshot-induced extremity fractures are typically not considered open fractures, there is controversy regarding wound management in the setting of operative fixation to limit infection complications. Previous studies have evaluated the need for a formal irrigation and debridement (I&D) prior to intra-medullary nailing (IMN) of gunshot-induced femur fractures but none have specifically evaluated tibias. By comparing primary IMN for tibial shaft fractures caused by low-velocity firearms additionally treated with a formal operative I&D (group 1) with those without an I&D (group 2), we sought to identify whether there are: differences in treatment group infection rates; particular fracture patterns more prone to infection; and patient characteristics more prone to infections...

BACKGROUND: Various techniques have been employed for the early detection of perioperative cerebral ischaemia and hypoxia. Cerebral near-infrared spectroscopy (NIRS) is increasingly used in this clinical scenario to monitor brain oxygenation. However, it is unknown whether perioperative cerebral NIRS monitoring and the subsequent treatment strategies are of benefit to patients. OBJECTIVES: To assess the effects of perioperative cerebral NIRS monitoring and corresponding treatment strategies in adults and children, compared with blinded or no cerebral oxygenation monitoring, or cerebral oxygenation monitoring based on non-NIRS technologies, on the detection of cerebral oxygen desaturation events (CDEs), neurological outcomes, non-neurological outcomes and socioeconomic impact (including cost of hospitalization and length of hospital stay)...

Stair descent (SD) is a common, difficult task for populations who are elderly or have orthopaedic pathologies. Joint torques of young, healthy populations during SD increase at the hip and ankle with increasing speed but not at the knee, contrasting torque patterns during gait. To better understand the sources of the knee torque pattern, we used dynamic simulations to estimate knee muscle forces and how they modulate center of mass (COM) acceleration across SD speeds (slow, self-selected, and fast) in young, healthy adults...

Background: The development of Deep Vein Thrombosis (DVT) is a major concern following orthopaedic surgery. No study has yet to compare the rate and risk factors for DVT between total joint and orthopaedic trauma patients. To evaluate if DVT prophylaxis for trauma should differ from total joints, we explored the rate and risk factors for DVT between both cohorts. Methods: Using a CPT code search from 2005 to 2013 in the ACS-NSQIP database, 150,657 orthopaedic total joint patients and 44,594 orthopaedic trauma patients were identified...

Background: Scaphoid fracture is the most common among carpal bone fractures, frequently imperceptible on initial radiographs. Tendency of scaphoid fracture to undergo in non-union makes it an important challenging injury for all orthopaedic surgeons. Displaced scaphoid fracture has high non-union rate in conservative management asserting the need to explore operative treatment. Materials and method: A prospective study was conducted in our institution in thirty patients in 20 to 50 year age group, for displaced scaphoid fracture (<30 days duration)...

Management of proximal and distal biceps tendon pathology is evolving. The long head of the biceps tendon, if inflamed, may be a pain-producing structure. In appropriately indicated patients, a symptomatic long head of the biceps tendon can be surgically managed via tenotomy, tenodesis, and/or superior labrum anterior to posterior repair. In some patients, primary superior labrum anterior to posterior pathology can be managed via biceps tenodesis. Determining which procedure is most appropriate and which technique and implant are preferred for a given patient with biceps tendon pathology is controversial...

Among the various pharmacological options to decrease peri-operative bleeding, tranexamic acid appears to be one of the most interesting. Several trials have consistently documented the efficacy of this synthetic drug in reducing the risk of blood loss and the need for allogeneic blood transfusion in patients undergoing total hip and knee arthroplasty. The safety of intravenous tranexamic acid in major orthopaedic surgery, particularly regarding the risk of venous thromboembolism, was systematically analysed in this review...

BACKGROUND: The use of less-invasive techniques in the treatment of displaced intra-articular calcaneal fractures (DIACFs) remains controversial. No prior meta-analysis has considered the influence of differences in the fracture type. Thus, our meta-analysis aimed to investigate the efficacy and safety of minimally invasive (MI) in Sanders type II and III fractures. MATERIALS AND METHODS: A comprehensive search was performed to identify RCTs comparing MI using sinus tarsi approach (STA) or percutaneous reduction (PR) to open reduction (OR) via extensile lateral approach (ELA) from the Cochrane Library, PubMed, Embase and CNKI...
