26 ± 114.93 μm at baseline to 454.70 ± 244.08 μm at 1-3 months; P less then 0.001). Repeat multilayer transplantation was required in 7 of the 23 patients included (30.4%), in 6 of whom the treated eye was stable at month 6. In 2 of the 23 patients, perforating keratoplasty became necessary. One patient also demanded such a procedure to improve his visual acuity. The success rate was 91.3% (n = 21). CONCLUSIONS Running resorbable suture fixation of multilayer AMs proved to be an efficient means for the treatment of noninfectious deep or small perforating corneal ulcers.PURPOSE To report a case of conjunctival epithelial ingrowth after penetrating keratoplasty. METHODS A 57-year-old woman with herpetic corneal keratitis, endotheliitis, and bullous keratopathy underwent penetrating keratoplasty (PKP) and secondary cataract surgery. One month after cataract surgery, an epithelial ingrowth was observed at the 5 o'clock donor host junction. Ingrowth extended into the anterior chamber and along the iris surface by 9 months. Another PKP was performed, and the excised graft was submitted for histopathology. Fasudil RESULTS The graft showed CK13-positive and CK3-negative cells lining the endothelial surface, indicating the conjunctival origin of ingrown epithelium. Ten months postoperatively, no recurrence of ingrowth was observed. CONCLUSIONS We experienced a rare case of conjunctival epithelial ingrowth after penetrating keratoplasty. There was no recurrence of the ingrowth after surgical removal, and the conjunctival origin may explain the relatively benign course of the complication.PURPOSE To examine and compare corneal cellular and subbasal nerve (SBN) characteristics in post-laser-assisted in situ keratomileusis ectasia (PLE) corneas, normal post-laser-assisted in situ keratomileusis corneas (PLC), keratoconus (KC) corneas, and normal virgin corneas (NC). METHODS In this cross-sectional comparative study, 18 PLE eyes of 11 patients, 18 PLC of 15 cases, 32 KC eyes of 32 patients, and 29 NC of 29 subjects were assessed using in vivo confocal microscopy. The density of the basal epithelial cell (BEC), anterior keratocyte, posterior keratocyte, and endothelial cell layers, as well as the characteristics of SBN fibers, was compared between the 4 groups. RESULTS The density of the BEC and anterior and posterior keratocyte layers was significantly lower in KC compared with NC (-650 ± 190, P = 0.013; -181 ± 39, P less then 0.001; and -36 ± 11, P = 0.021, respectively). However, there was no significant difference between PLE and PLC regarding these parameters (all Ps ≥ 0.6). Mean SBN parameters, including central corneal nerve branch density, nerve fiber length, total branch density, and nerve fiber area, were significantly lower in KC compared with NC and in PLE compared with PLC (all Ps ≤ 0.021). CONCLUSIONS The pathophysiology of PLE seems to differ from KC. Apparent changes in the BEC and anterior and posterior keratocytes associated with KC were not observed in PLE. However, SBNs seem to be involved in both conditions.PURPOSE The purpose of this study was to evaluate the association between small left atria (LA) according to computed tomography pulmonary angiography (CTPA) and mortality among individuals without pulmonary embolism, and to examine which volumes begin to portend adverse outcomes. MATERIALS AND METHODS Left atrial volume indices (LAVIs) of 752 consecutive patients who underwent CTPA, in which pulmonary embolism were ruled out, were measured retrospectively using an automatic 4-chamber volumetric analysis software. Groups of 5 percentiles within the lower quartile were investigated, and the interquartile range (25th to 75th percentiles) was regarded as the control group. RESULTS Patients within the lower 25th LAVI percentiles ( less then 33 mL/m; n=188) were younger and had less cardiovascular morbidities, while malignancies were less common in the control group (LAVI 33 to 54 mL/m; n=376). Percentiles 5th to 25th did not demonstrate an independent association with mortality. After adjustment for baseline characteristics, the risk for 30-day and 1-year mortality was 5.6 (95% confidence interval 2.1-14.8, P=0.001) and 6.1 (95% confidence interval 2.4-15.1, P less then 0.001) times higher, respectively, among the lowest five LAVI percentiles ( less then 24 mL/m) compared with the control group. Among patients with small LA who died within 1 year, 83% had a diagnosis of malignancy. Albeit, only a minority (3%) of patients with malignancies had small LA. CONCLUSIONS Individuals undergoing CTPA whose LAVI is within the lowest five percentiles have a markedly increased risk for short-term and long-term mortality. The risk can probably be attributed to an underlying malignancy. The feasibility of 4-chamber volumetric analysis while avoiding a time-consuming process due to the automatic properties enables the introduction of this feature to clinical practice.BACKGROUND For almost 30 years, bone-anchored prostheses have offered an alternative solution to prosthetic sockets by attaching the artificial limb directly to the femoral residuum by means of an osseointegration implant. Osseointegration implant surgery was introduced in our center in 2009. The aim of the present study is to report on safety, prosthesis-wearing time, and health-related quality-of-life (HRQoL) for patients with femoral bone-anchored prostheses during a 5-year follow-up period. METHODS All patients who underwent implantation of a press-fit osseointegration implant between May 2009 and November 2013 were eligible for the present study. Implantation was performed in 2 stages. Adverse events included infectious complications (grade 1 to 4), aseptic loosening, breakage, stoma-redundant tissue, and stoma hypergranulation. Prosthesis-wearing time and HRQoL were measured with the Questionnaire for Persons with a Transfemoral Amputation (Q-TFA) prosthetic use score and global score, respectively. RESlications and prevention of osseointegration implant breakage. LEVEL OF EVIDENCE Therapeutic Level IV.

Because of current limitations in resources, many elective surgeons have been forced to venture into utilizing telemedicine, in which the standards for orthopaedic examinations have not previously been fully developed. We report our experience with protocols and methods to standardize these visits to maximize the benefit and efficiency of the virtual orthopaedic examination. At the time of scheduling, patients are asked to prepare for their virtual visit and are given a checklist. In addition to confirming audiovisual capabilities prior to the visit, patients are given specific instructions on camera positioning, body positioning, setting, and attire to improve the efficiency of the visit. During the examination, digital tools can be utilized as needed. In the setting of outpatient injury evaluations, a systematic virtual examination can aid in triaging and managing common musculoskeletal conditions. With the rapid incorporation of telehealth visits, as well as the unknown future with regard to the pandemic, the utilization and capabilities of telemedicine will continue to expand. Future directions include the development of validated, modified examination techniques and new technology that will allow for improved interactive physical examinations, as we rapidly move forward into the realm of telemedicine due to unexpected necessity.STUDY DESIGN Retrospective cohort study. OBJECTIVE To evaluate the role and value of whole-spine computerized tomography (WSCT) vs. radiographs and targeted CT to tender spinal regions in patients with diffuse idiopathic skeletal hyperostosis (DISH) after low-energy trauma. SUMMARY OF BACKGROUND DATA Subjects with DISH are prone to spinal fractures even after low-impact trauma due to a rigid spinal structure. METHODS One-hundred and forty-seven subjects (average age 83 years, MF 64/83) with verified DISH (Resnick and Niwayama radiographic criteria) on WSCT who were admitted to the emergency room (ER) after low-energy trauma and for whom there were radiographs of at least the thoracic and lumbar spine were evaluated for the presence of acute spinal fractures on both radiographs and WSCT. Agreement between fracture location and spinal tenderness location (cervical, thoracic, or lumbar) as reported in the medical record was evaluated. RESULTS Significantly more acute fractures were detected on WSCT compared to radiographs (55 and 32, P  less then  0.00001, respectively). The site of tenderness was not indicative of the fractured spinal segment in 57% of all acute fractures (7 cervical, 15 thoracic, and 16 lumbar). No fracture was detected on WSCT in 10 subjects with an unspecified pain location. Multilevel distant fractures were detected in two patients with a specified pain location to only one of the fractures. CONCLUSION WSCT in DISH subjects after low-impact trauma is mandatory due to the high prevalence of acute fractures and the low specificity for fracture detection on radiographs. A targeted CT approach to the tender spinal segment proved to be inadequate and would have missed 57% of the acute single fractures with incompatible spinal tenderness location. These results support the significant role of WSCT in the ER setting for detecting and pinpointing the spinal fracture site of DISH subjects who present with low-impact trauma. LEVEL OF EVIDENCE 3.STUDY DESIGN A retrospective review of prospectively collected data. OBJECTIVE To compare quality of life (QOL) outcomes of posterior lumbar interbody fusion (PLIF) with lateral lumbar interbody fusion (LLIF) using reports from patients obtained at the 2-year postoperative follow-up. SUMMARY OF BACKGROUND DATA Indirect decompression with LLIF is used to treat degenerative lumbar diseases that require neural decompression. However, the difference in improvement in QOL following indirect decompression compared with direct neural decompression using PLIF is unclear. METHODS We enrolled 284 consecutive patients with degenerative lumbar spondylolisthesis in the present study, 203 who underwent PLIF and 81 who underwent LLIF. All patients completed a minimum of 2 years of follow-up. We evaluated the effectiveness of surgery in each category of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ). RESULTS The results of preoperative JOABPEQ and the severity of thecal sac stenosis were not significantly different between PLIF and LLIF, neither was the rate of perioperative complications (14.8% and 15.4% for the PLIF and LLIF groups, respectively; p = 0.91). The effectiveness at 2 years postoperatively was almost the same for all five domains of the JOABPEQ 62.6% and 68.9% for pain-related disorders (p = 0.34), 38.3% and 42.7% for lumbar spine dysfunction (p = 0.51), 65.8% and 67.5% for gait disturbance (p = 0.79), 53.5% and 48.8% for social life dysfunction (p = 0.47), and 29.1% and 33.3% for psychological disorders (p = 0.48) following PLIF and LLIF, respectively. Visual analogue scale results for back and lower-limb pain and numbness of the lower limbs were almost the same for both groups. No significant differences were observed in terms of perioperative complications and radiographical outcomes. CONCLUSIONS Indirect decompression using LLIF improves QOL and radiographical outcomes to a comparable degree as direct decompression via PLIF. LEVEL OF EVIDENCE 4.
