Background: Minimally invasive (MIS) treatment of hallux valgus (HV) deformity is increasing in popularity. A 2-mm diameter burr is used to create a distal first metatarsal osteotomy prior to capital fragment translation and fixation. The metatarsal will shorten by the burr's diameter (2 mm). Plantar or dorsal capital fragment displacement may also cause load transference and possibly transfer metatarsalgia. The purpose of this study is to examine the effect of MIS HV on forefoot loading mechanics with respect to metatarsal shortening and sagittal plane displacement., Methods: Four lower-limb cadaveric specimens were studied. A pedobarography pressure-sensing mat was used to record forefoot plantar pressure in a controlled weight-bearing stance position. Control and postosteotomy measurements were obtained with the capital fragment fixated in 3 possible positions: 0 mm, 5 mm dorsal, and 5 mm plantar displacement. Pedobarography data yielded pressure data within measurable graphical depictions. Raw mean contact pressure measurements were taken under the first and fourth metatarsal heads to establish medial and lateral forefoot loading pressure ratios. An a priori power analysis was performed based on previous peer-reviewed pedobarographic data, and our study was adequately powered., Results: Around 40 measurements were recorded, and ratios of medial-to-lateral forefoot loading were constructed. Medial forefoot pressure control versus 0 mm displacement, and control versus dorsal displacement were not found to be statistically significant ( p  = 0.525, p  = 0.55, respectively). Medial pressure significantly increased when comparing control versus plantar displacement ( P  = .006). Lateral pressure significantly increased with dorsal displacement of the osteotomy ( P  = .013)., Conclusion: Our study found that MIS HV correction did not cause an increase in lateral forefoot pressure loading when sagittal plane displacements were controlled. Plantar displacement increased medial loading, and dorsal displacement increased lateral loading. It may be valuable for surgeons to consider metatarsal head position postosteotomy, as a decrease in medial loading and subsequent increase in lateral loading may lead to lateral forefoot pain and transfer metatarsalgia., Levels of Evidence: IV., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: The purpose of this study is to evaluate patients' knowledge of the professional training between doctors of podiatric medicine (DPM) and orthopedic surgery doctors (MD or DO), patients' confidence in understanding these differences, and factors that are important to patients when selecting a provider. Design: A 28-question survey was administered to new patients who were referred to the foot and ankle service in an orthopedic department. Survey questions included data on patient demographics, patient opinion, and knowledge of differences between podiatrists and orthopedic surgeons. Setting: Patient surveys were administered at Froedtert Memorial Lutheran Hospital in Wauwatosa, Wisconsin USA and Mayo Clinic in Jacksonville, Florida USA. Participants: 186 patients completed the survey. Methods: Study population characteristics and survey results were analyzed with variance (ANOVA), Fisher's Exact test, binomial tests, and chi-square tests. Results: Of the 186 patients who completed the entire survey, 108 chose "orthopedic surgeon" as their provider of preference for any foot or ankle injury. Patients preferred an orthopedic surgeon over a DPM for ankle (65.7% vs. 9.6%, P <0.01) and knee injuries (86.0% vs. 5.0%, P <0.01), while they preferred a DPM for toe pain (29.4% vs. 42.2%, P <0.03). 80.8% of patients thought orthopaedic surgeons and podiatrists undergo the same professional training. Conclusions: Patients have poor understanding of the different provider training between a DPM and orthopedic surgeon. Patients showed a preference based on anatomic location with podiatrist favored for conditions affecting the toes. Those patients that demonstrate a higher level of knowledge of the specialties were more likely to prefer an orthopaedic surgeon. Other factors, such as physician interpersonal skills and provider availability, may be more important for patients than training backgrounds., (© 2022 Marshfield Clinic Health System.)

Background: Ehlers-Danlos syndromes (EDSs) are connective-tissue disorders resulting in joint laxity. Soft-tissue stability is a concern in these patients when they undergo total hip arthroplasty (THA). Our purpose was to compare THAs in the population with EDS with a matched control undergoing THA for osteoarthritis., Methods: Thirteen patients with EDS underwent THA from 1997 to 2017. Matching was 1:3 with a control group of patients who underwent THA for osteoarthritis. Matching was based on the gender, age, and length of follow-up., Results: We found no difference in demographics or postoperative Harris Hip Scores between the cohorts ( P > .05). Two patients (15.4%) with EDS and 2 patients (5.1%) in the control group suffered a dislocation. We found no difference in the reoperation or revision rate between the groups ( P  = .28)., Conclusion: Patients with EDS have a significant improvement in postoperative Harris Hip Scores after THA. These patients also have a high dislocation rate after surgery, and alternative approaches and technologies such as dual-mobility components should be considered to reduce the rate of dislocation in this population., (© 2020 The Authors.)

Introduction: Referred to as the "fifth vital sign", pain is unique in that it cannot be obtained accurately by objective measurements. Instead, providers rely on patient-reported scales, such as the numerical rating scale (NRS), to determine a patient's pain level. Research has shown that patients report different pain scores to nurses and physicians in the clinic setting. It is unknown if this also occurs in the acute postoperative period. We hypothesized that patients report similar pain scores to the nursing staff and physician postoperatively. The primary aim of this study was to examine the degree of agreement between these patient-reported pain scores., Methods: A prospective study was conducted on 90 postoperative patients. During rounds, the surgeon collected a patient-reported pain score using the 11-point verbal NRS. Following rounds, the nursing staff obtained a pain score using the same scale. The patient was blinded to the study., Results: The median score reported to both the surgeon and nurses was 3 (range: 0-10), with a median difference of 0 (range: -2.5 to 7). Fifty-four percent of patients reported the same score to both the surgeon and the nurse and 88% of patients reported scores within a 1-point difference. This corresponded to an interclass correlation coefficient of 0.90, indicating very good agreement. The degree of agreement in pain scores reported to surgeons and nurses was consistent according to sex and age., Conclusion: The results of the study demonstrate a high degree of agreement between the pain scores reported by the patients to both the nursing staff and the surgeon postoperatively, with 88% of the scores at most being 1-point different., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2019, Foster et al.)

Purpose: To evaluate the hypothesis that platelets and fibrin differentially accrue at microvascular anastomoses in arteries versus veins and under different pharmacologic conditions., Methods: We evaluated mouse arterial and venous anastomoses with intravital fluorescence imaging, using fluorophore-labeled platelets and anti-fibrin antibodies to measure the extent of thrombus component development in the intraluminal anastomotic site. We evaluated systemic heparin or eptifibatide (platelet aggregation inhibitor) to determine their relative influences on thrombus composition., Results: Platelets accumulated rapidly in both arterial and venous repairs, and then fell in number after 10 to 30 minutes of reflow. Fibrin had a relatively steady development over 60 minutes in veins, with a more variable increase in arteries. Heparin reduced platelet accumulation in arteries and fibrin development in veins. Eptifibatide reduced platelets in both arteries and veins and had an apparent effect on lowering the amount of fibrin in veins., Conclusions: These findings show that platelets have a rapid, transient response, whereas fibrin has a slower, more sustained accrual in both arterial and venous anastomoses. Furthermore, inhibition of either coagulation or platelet aggregation can influence presumably non-targeted components of thrombosis in vascular repairs of both arteries and veins., Clinical Relevance: Preventing replantation failure using antithrombotic therapies requires a better understanding of the effect of each pharmacologic compound on the various aspects of thrombogenesis., (Copyright © 2013 American Society for Surgery of the Hand.
