We report the measurement of infrared transmission large C60 single crystals. The spectra exhibit a very rich structure with over 180 vibrational absorptions visible in 100 - 4000 cm-1 range. Many silent modes are observed to have become weakly IR-active. also observe number higher order combination modes. temperature (77K 300K) and pressure (0 25KBar) dependencies these were measured presented. Careful analysis IR conjunction Raman scattering data showing second neutron data, allow...
There remains no consensus regarding the role of computed tomography (CT) scans in preoperative planning for malleolar ankle fractures. The aim this study was to determine CT on operative these fractures.A retrospective analysis performed 100 consecutive patients treated at our institution fractures (AO type 44) with both radiographs and scans. Six participants reviewed available formulated an (or nonoperative) plan including positioning, approach, fixation. Participants then analyzed same...
Peroneal tendon displacement (subluxation or dislocation) accompanying an intra-articular calcaneal fracture is often undetected and under-treated. The goals of this study were to determine (1) the prevalence peroneal fractures, (2) association with classifications, (3) heel width, (4) rate missed diagnosis on radiographs computed tomography (CT) scans resulting treatment rate.A retrospective radiographic review all fractures presenting at three institutions from June 30, 2006, 2011, was...
There are conflicting data regarding the benefits of delaying operative fixation calcaneus fractures to decrease wound complication rates. The purpose this study was examine effect on rates as well identify other risk factors.A retrospective review at 4 institutions, including 24 surgeons, identified 405 closed, operatively treated, intra-articular fractures. We compared with and without complications regards patient demographics, medical factors, fracture severity, time fixation, approach,...
Talar displacement is considered the main predictive factor for poor outcomes and development of post-traumatic osteoarthritis after ankle fractures. Isolated lateral talar translation, as previously studied by Ramsey Hamilton using carbon powder imprinting, does not fully replicate multidirectional joint subluxations seen in The purpose this study was to analyze influence multiple uniplanar displacements on tibiotalar contact mechanics utilizing weightbearing computed tomography (WBCT)...
Background: Chronic Achilles tendon ruptures (CATRs) present significant challenges because of delayed diagnosis and more complicated salvage treatments that can result in unfavorable outcomes increased rates adverse events. Various reconstructive surgical options have been described, each with its own unique advantages disadvantages. Comprehensive comparison these techniques, however, is lacking. This meta-analysis aimed to compare clinical following 3 the most commonly used techniques...
175 Background: It is well-known that patients with liver metastases from metastatic castration resistant prostate cancer (mCRPC) have poorer or transient responses to many forms of systemic therapy. Data on outcomes following treatment Lutetium-177–PSMA-617 scarce. The VISION trial reports hazard ratios for overall survival in the subgroup without disclosing absolute duration survival. Using real-world clinical data, we examine this important patients, describing their PSA response rates...
An inherent deficiency in the understanding of biomechanics fractures is reliance on cadaveric or other nonphysiological injury models resulting from prohibitive ethical and practical considerations conducting studies live participants. We describe a novel methodology for studying mechanisms using vivo videos obtained Youtube.com demonstrating injuries as they occur real time correlating them with radiographs.Over 1000 video clips potential ankle were assessed clear visualization mechanism...
Background. The purpose of this study was to evaluate prognostic predictors complications and need for secondary surgery in a series calcaneal avulsion fractures. Methods. Thirty-three patients who sustained extra-articular fractures from 2002 2011 were retrospectively identified. Main outcome measurement surgical procedures. Secondary such as soft tissue loss fixation noted. Prognostic factors measures Results. There operations 12 cases. Of those, 10 (83%) had wound 5 (41.7%) failure...
Background: The aim of this study was to determine the ability Harris heel view confirm placement sustentacular screw during calcaneal fixation. Methods: A 4.0 cancellous placed in a cadaveric specimen, from lateral medial 5 configurations: (1) within sustentaculum, (2) misdirected inferiorly (3) superiorly (4) anteriorly and (5) posteriorly sustentaculum. views were obtained at angulations analyzed placement. Results: anatomically radiographically confirmed by be sustentaculum all views. An...
There is limited evidence that syndesmotic implant removal (SIR) beneficial. However, many surgeons advocate based on studies suggesting improved motion. Methodologic difficulties make the validity and applicability of previous works questionable. The purpose this study was to examine effect ankle dorsiflexion after SIR using radiographically measured motion before screw utilizing a standardized load.All patients undergoing isolated were candidates for inclusion. Dorsiflexion...
Femoral skeletal traction assists in the reduction and transient stabilization of pelvic, acetabular, hip, femoral fractures when splinting is ineffective. Traditional teaching has recommended a medial entry site for insertion pin order to minimize injury artery as it passes through Hunter's canal. The present anatomical study evaluates risk other neurovascular structures using lateral approach.Six embalmed cadavers (twelve femurs) were obtained dissection. Steinman pins drilled from at...
The majority of retained syndesmotic screws will either loosen or break once the patient resumes weight-bearing. While evidence is limited, anecdotal experience suggests that intraosseous screw breakage may be problematic for some patients due to painful bony erosion. This study seeks identify incidence breakage, variables predict and whether associated with higher rates implant removal secondary pain.Five hundred thirty-one undergoing stabilization were screened, which 43 (with 58 screws)...
Background: The purpose of this study was to determine whether obtaining a radiograph the uninjured contralateral calcaneus (template) before surgery allowed for more precise restoration Bohler’s angle and calcaneal length when performing open reduction internal fixation (ORIF) intra-articular fractures. Methods: Patients who sustained an fracture requiring met inclusion criteria were prospectively randomized into those had preoperative template obtained review at time ORIF (group 1) versus...
Syndesmotic instability is a source of significant pain and disability. Both subtle gross diastasis, whether acute or chronic, require stabilization may benefit from reconstruction with ligamentous augmentation. The use nonabsorbable suture-tape has emerged as promising operative strategy, allowing surgeons to anatomically reconstruct the syndesmosis, in particular anterior inferior tibiofibular ligament. current work provides detailed description technique preliminary results patient cohort...
Background: Crush injuries to the foot are a common workplace injury and significant source of morbidity, disability lost wages. Many regulatory bodies including Occupational Safety Health Administration (OSHA) recommend use safety shoes in certain occupations help protect against these occupational hazards. However there remains controversy paucity published data regarding protection afforded by steel toe cap regards clinical pattern. This study looks investigates protective influence on...
This article describes a case of an ankle fracture following hip arthroscopy. A 58-year-old woman underwent arthroscopy for labral tear. She was placed in lateral decubitus position with her foot padded boot. Traction maintained approximately 30 minutes. instructed to bear weight as tolerated crutches postoperatively. At 2-week follow-up, she reported ipsilateral pain. Radiographs revealed minimally displaced medial malleolus fracture. treated cast followed by cam walker boot and...
