Retinal diseases, such as age-related macular degeneration (AMD), are the leading cause of blindness in the elderly population. Since no known cures are currently present, it is crucial to diagnose the condition in its early stages so that disease progression is monitored. Recent advances show that the mechanical elasticity of the posterior eye changes with the onset of AMD. In this work, we present a quantitative method of mapping the mechanical elasticity of the posterior eye using confocal shear wave acoustic radiation force optical coherence elastography (SW-ARF-OCE). This technique has been developed and validated with both an ex-vivo porcine tissue model and a customized in-vivo rabbit model, which both showed the quantified elasticity variations between different layers. This study verifies the feasibility of using this technology for the quantification and diagnosis of retinal diseases from the in-vivo posterior eye.In this work, we investigate two-dimensional arrays of High-T C superconducting quantum interference devices (SQUIDs) for optimization of their electrical transport characteristics. Specifically, we look at devices with different electrode configurations in between the series segments to gain insight into how the array spacing, in the direction of the bias current, affects the voltage magnetic field characteristics. Our results suggest that for spacing dimensions greater than the penetration depth interactions are minimal. Furthermore, comparisons of voltage field characteristics reveal higher modulation voltages and narrower peaks with as the numbers of SQUIDs in the parallel direction increases from 1 to 6. For larger numbers of SQUIDs in parallel greater than 6 little change is observed. These results suggest a pathway to SQUID array scaling for very large numbers of SQUIDs within in a small area.The purpose of this study was to identify the vessels feeding the FPL to reduce the FPL tendon ruptures related to VLP surgery. The dissections identified the FPL, radial artery (RA) and anterior interosseous artery (AIA). The mean number of branches of the RA and AIA to the FPL was 2.0 and 4.0, respectively. The distance from volar prominence of the radius to the most distal branch of the RA and AIA was 43 mm and 57 mm, respectively. The most distal branch would be frequently injured during VLP surgery because of its proximity to the surgical field. © 2020 Professor P K Surendran Memorial Education Foundation.

Methods Analysis of consecutive patients undergoing surgery for distal biceps tendon ruptures by a single surgeon. Measurements regarding the site and degree of tendon retraction in relation to anatomical landmarks following rupture were correlated with intraoperative findings. Postoperative functional outcomes were assessed in cases with >12 months follow-up. Results 24 cases of distal biceps tendon ruptures treated surgically were identified. Mean tendon retraction was 6.0 cm (range 1.2-9.5) from the radial tuberosity. 22 cases were reattached successfully. 2 required ligament augmentation/bridging using a synthetic ligament. In 2 cases the tendon could not be reattached due to poor quality of the tendon stump. Ability to reattach the tendon was unrelated to degree of radiological retraction or chronicity of rupture. Degree of retraction was not related to rupture chronicity. All reattachments healed with no re-rupture at follow-up with no substantial motion loss. In 17 cases >12months follow-up the DASH and OES were not related to retraction or chronicity of rupture. Conclusions Radiological retraction and chronicity are not related to the ability to reattach distal biceps tendon ruptures or their clinical outcomes, hence should not discourage surgical exploration and attempted reattachment. Substantial tendon retractions can occur acutely and reattachment in considerable flexion did not produce any significant motion loss. Some cases will need augmentation or gap bridging and augmentation devices need to be available at surgery. Level of evidence Level IV Retrospective Study Defined.

Methods The San Francisco Match's website identified directors encompassing 8 subspecialties. The Scopus database identified the number of publications, citations, and h-index for each director. H-index was assessed with/without self-citation. Results Mean publications, citations, self-citation rate, and h-index for the 446 directors were 71.2, 1816, 3.86%, and 18.3, respectively. Excluding self-citations reduces mean h-index to 18.0; and h-index changed by ≤ 1 integer in 95% of directors. Conclusions Self-citation has minimal impact among fellowship directors and should not be adjusted for when considering external funding.The purpose of this study is to assess the role of bioskills in orthopaedic and neurosurgical resident education. A survey of the utilization and perceived efficacy of bioskills was submitted to Lumbar Spine Research Society (LSRS) members. 36/104 surgeons responded, including 25 orthopaedic, 7 neurosurgical, and 4 integrated respondents. 63% of orthopaedic and 83% of neurosurgery faculty, reported using bioskills. When asked if completion of bioskills modules would encourage advancing trainees' participation (1-10 scale, 10 greatly increase), neurosurgical faculty reported 4.00 versus orthopaedics 6.43. Although orthopaedic faculty perceive greater efficacy of bioskills, the clinical impact of this difference remains uncertain. © 2020 Professor P K Surendran Memorial Education Foundation.

Methods The PubMed and Cochrane databases were searched for relevant papers. Results Thirteen articles were included. The mean clinical/functional subjective scores significantly improved postoperatively. The implant revision rate for primary and revision RTSA was 3.1% and 21.1% respectively. The reoperation rate was 3.5% and 24.4% respectively. Conclusions There was moderate evidence that bone grafting is effective for glenoid defects in primary RTSA. Further high-quality research is required about revision RTSA for moderate-to-severe glenoid defects. © 2019 Professor P K Surendran Memorial Education Foundation. Published by Elsevier B.V.
