REVIEW
Mark W Allen, David J Jacofsky
Since the initial design of surgical theaters, the thermal environment of the operating suite itself has been an area of concern and robust discussion. In the 1950s, correspondence in the British Medical Journal discussed the most suitable design for a surgeon's cap to prevent sweat from dripping onto the surgical field. These deliberations stimulated questions about the effects of sweat-provoking environments on the efficiency of the surgical team, not to mention the effects on the patient. Although these benefits translate to implant-based orthopedic surgery, they remain poorly understood and, at times, ignored...

BACKGROUND: Although a multidisciplinary approach is often recommended to treat intractable pain, this approach does not completely prevent uncontrolled pain in some patients. The aim of this retrospective study was to investigate the exacerbating factors of prolonged, intractable pain among patients being treated at a pain liaison clinic. METHODS: The participants of this study were 94 outpatients (32 men, 62 women) with chronic intractable pain who visited our hospital between April 2013 and February 2015...

More than two million people tear their anterior cruciate ligament (ACL) each year, and ACL reconstruction occupies a significant proportion of everyday orthopedic practice, being one of the most commonly performed sports medicine surgical procedures. Patients with postoperative symptoms are frequently imaged to monitor ligament grafts and to identify complications. Given the number of patients undergoing ACL reconstruction, knowledge of the potential complications of this surgery is essential for radiologists...

Fast and stable repair of segmental bone defects remains a challenge for clinical orthopedic surgery. In recent years, porous tantalum has been widely applied in clinical orthopedics for low modulus of elasticity, with three-dimensional microstructures similar to cancellous bone and excellent biocompatibility. To further improve bone the repairing ability of porous tantalum, the cyclo(-RGDfK-) peptide was coated on the surface of porous tantalum scaffolds. A model of 15 mm segmental defect was made at the midshaft of right radius in New Zealand White rabbits...

This article reports the use of elastic suture as an adjuvant in surgical wound closure caused by decompressive fasciotomy after compartment syndrome associated with a compound fracture of the tibia. Widely used in other medico-surgical specialties, this technique is unusual in orthopedics surgery, but the simplicity of the procedure and the successful outcome observed in this case allows for its consideration as indicated for situations similar to that presented in this study.

The role of orthopedic surgery in Ehlers-Danlos syndrome is inherently controversial, opaque to most patients and many medical providers, and difficult to discern from available medical literature. Non-operative treatment is preferable, but for carefully selected patients, specific joint stabilization and nerve decompression procedures can provide symptomatic relief when conservative measures fail. © 2017 Wiley Periodicals, Inc.

INTRODUCTION: Tibial plateau fractures often occur in conjunction with soft-tissue injuries of knees. The hypothesis of this study is that parameters of CT imaging can predict intra-articular soft-tissue injuries. PATIENTS AND METHODS: Patients who underwent arthroscopically assisted reduction and internal fixation (ARIF) for acute tibial plateau fractures performed by a single orthopedic surgeon between 2005 and 2015 were included in this retrospective study. Patients with concomitant ipsilateral femoral fractures, who had received revision surgery or who had undergone index surgery more than 30days from the event were excluded...

PURPOSE: Patient-specific musculoskeletal biomechanical simulation is useful in preoperative surgical planning and postoperative assessment in orthopedic surgery and rehabilitation medicine. A difficulty in application of the patient-specific musculoskeletal modeling comes from the fact that the muscle attachment regions are typically invisible in CT and MRI. Our purpose is to develop a method for estimating patient-specific muscle attachment regions from 3D medical images and to validate with cadaver experiments...

In recent years, US hospitals have switched from use of unfractionated heparin to use of low-molecular-weight heparin, which is associated with lower risk of heparin-induced thrombocytopenia (HIT). In the study reported here, we retrospectively searched the Nationwide Inpatient Sample (NIS) for patients who were at least 18 years old and received a diagnosis of HIT between 2009 and 2011. Our goal was to get an updated perspective on the incidence and economic impact of HIT. We calculated the incidence of HIT overall and in subgroups of patients who underwent cardiac, vascular, or orthopedic surgery...
