The treatment of high-energy open tibia fractures is challenging in both the military and civilian environments. Treatment with modern ring external fixation may reduce complications common in these patients. However, no study has rigorously compared outcomes of modern ring external fixation with commonly used internal fixation approaches. The FIXIT study is a prospective, multicenter randomized trial comparing 1-year outcomes after treatment of severe open tibial shaft fractures with modern external ring fixation versus internal fixation among men and women of ages 18-64...

BACKGROUND: Currently, the most difficult-to-treat tibial plateau fractures are complex, comminuted fractures, which result from high-energy trauma. The anatomical reconstruction of the articular surface and the preservation of the soft tissue envelope are required for a good functional result. The aim of this study is to perform a biomechanical evaluation of three constructs used in the treatment of bicondylar fractures: the L‑shaped plate, the LCP locking plate, and the hybrid external fixator...

BACKGROUND: Moderate graft pretensioning in anterior cruciate ligament (ACL) reconstruction is paramount to restore knee stability and normalize knee kinematics. However, little is known about the effect of graft pretensioning on graft-to-bone healing after ACL reconstruction. HYPOTHESIS: Moderate graft pretensioning will improve bone formation within the bone tunnel after ACL reconstruction, resulting in superior load to failure. STUDY DESIGN: Controlled laboratory study...

BACKGROUND: Proximal humerus fractures are common injuries. Locking plates and anterograde medullary nails are the two most common fixation devices used when open reduction and internal fixation (ORIF) is indicated. Complications related to fracture and to hardware are numerous, especially shoulder stiffness. The goal of this study is to report the clinical outcomes of gleno-humeral arthroscopic arthrolysis combined with hardware removal. METHODS: A total of 58 patients (25 men, 33 women) with a mean age of 58 years (24-79) were reviewed retrospectively...

INTRODUCTION: Fracture of the distal end of radius represents the most common fracture of the upper extremity accounting for 16-20% of all fractures. Plating is now emerging as the gold standard for management of distal radius fractures due to increased rate of complications such as malunion, subluxation/dislocation of distal radio-ulnar joint or late collapse of fracture. Procedures such as closed reduction and cast immobilization, ligamentotaxis with external fixator and percutaneous pin fixation are no longer acceptable...

Offloading is a cornerstone in managing diabetic plantar foot ulcers; however, it often represents one of the most challenging aspects of treatment for clinician and patient alike. The authors present a case of a 61-year-old African American man with type 2 diabetes and a limb-threatening plantar foot ulcer that required aggressive wound and surgical management. Due to the heavy drainage and patient adherence issues, traditional offloading techniques such as total contact cast, DH Pressure Relief Walker (Össur, Foothill Ranch, CA), and wedge shoes, among others, were not viable options...

BACKGROUND: The treatment of pilon tibia fractures is challenging. Anatomical reduction of the joint surface is essential. Excessive soft-tissue dissection may interfere with the blood supply and can result in nonunion. We sought to compare the outcomes of distal tibia fractures treated with medial locking plates versus circular external fixators. METHODS: We retrospectively evaluated 41 consecutive patients with closed pilon tibia fractures treated with either minimally invasive locking plate osteosynthesis (n = 21) or external fixation (EF) (n = 20)...

BACKGROUND: Floating pubic symphysis (FPS) is a relatively rare injury caused by high-energy mechanisms. There are several fixation methods used to treat FPS, including external fixation, subcutaneous fixation, internal fixation, and percutaneous cannulated screw fixation. To choose the appropriate fixation, it is necessary to study the biomechanical performance of these different methods. The goal of this study was to compare the biomechanical characteristics of six methods by finite element analysis...

Age-related Macular Degeneration (AMD) is one of the leading causes of blindness in the elderly. Visual loss associated with AMD often results in a central scotoma which is an alteration in the central vision, leading to distortion or loss of vision. Current methods of detecting AMD are typically manual, require holding fixation and an external response trigger. In this paper, we propose the use of eyegaze tracking to detect for the presence of AMD, using a simple set of test patterns. Experimental results show that the derived eyegaze measurements can help to identify individuals with AMD from healthy individuals...

Recent reports suggest the presence of a rare fracture type for which reduction and fixation cannot be achieved with volar locking plate (VLP). In particular, it is difficult to achieve reduction and fixation with volar lunate facet (VLF) fragments present on the volar ulnar aspect of the lunate facet, because of the anatomical structure and biomechanics in this region. Herein, we report two challenging cases of difficulty in fixation of the VLF fragment in distal radius fracture. For this fracture type, it is most important to identify the volar ulnar bone fragment before surgery; it may also be necessary to optimize distal placement of the VLP via a dual-window approach and to apply additional fixations, such as a small plate, anchor, and/or external fixation...

For eyes with deficient capsular support, intraocular lens (IOL) implantation has long been a technical challenge. Recently, intrascleral fixation of the haptics of a three-piece posterior chamber IOL has become a popular option. In this procedure, externalization of the leading haptic during IOL injection is a stressful step. We present a modified technique to improve the ease and safety of this step. Our modified technique involves IOL injection with a motorized injector with several important modifications described here...
