Background: Common questions about shoulder arthroplasty (SA) searched online by patients and the quality of this content are unknown. The purpose of this study is to uncover questions SA patients search online and determine types and quality of webpages encountered. Methods: The "People also ask" section of Google Search was queried to return 900 questions and associated webpages for general, anatomic, and reverse SA. Questions and webpages were categorized using the Rothwell classification of questions and assessed for quality using the Journal of the American Medical Association (JAMA) benchmark criteria. Results: According to Rothwell classification, the composition of questions was fact (54.0%), value (24.7%), and policy (21.3%). The most common webpage categories were medical practice (24.6%), academic (23.2%), and medical information sites (14.4%). Journal articles represented 8.9% of results. The average JAMA score for all webpages was 1.69. Journals had the highest average JAMA score (3.91), while medical practice sites had the lowest (0.89). The most common question was, "How long does it take to recover from shoulder replacement?" Conclusions: The most common questions SA patients ask online involve specific postoperative activities and the timeline of recovery. Most information is from low-quality, non-peer-reviewed websites, highlighting the need for improvement in online resources. By understanding the questions patients are asking online, surgeons can tailor preoperative education to common patient concerns and improve postoperative outcomes. Level of evidence: IV.

Background: Massive rotator cuff tears (RCTs) are complicated by muscle atrophy, fibrosis, and intramuscular fatty degeneration, which are associated with postoperative tendon-to-bone healing failure and poor clinical outcomes. We evaluated muscle and enthesis changes in large tears with or without suprascapular nerve (SN) injury in a rat model. Methods: Sixty-two adult Sprague-Dawley rats were divided into SN injury (+) and SN injury (-) groups (n=31 each), comprising tendon (supraspinatus [SSP]/infraspinatus [ISP]) and nerve resection and tendon resection only cases, respectively. Muscle weight measurement, histological evaluation, and biomechanical testing were performed 4, 8, and 12 weeks postoperatively. Ultrastructural analysis with block face imaging was performed 8 weeks postoperatively. Results: SSP/ISP muscles in the SN injury (+) group appeared atrophic, with increased fatty tissue and decreased muscle weight, compared to those in the control and SN injury (-) groups. Immunoreactivity was only positive in the SN injury (+) group. Myofibril arrangement irregularity and mitochondrial swelling severity, along with number of fatty cells, were higher in the SN injury (+) group than in the SN injury (-) group. The bone-tendon junction enthesis was firm in the SN injury (-) group; this was atrophic and thinner in the SN injury (+) group, with decreased cell density and immature fibrocartilage. Mechanically, the tendon-bone insertion was significantly weaker in the SN injury (+) group than in the control and SN injury (+) groups. Conclusions: In clinical settings, SN injury may cause severe fatty changes and inhibition of postoperative tendon healing in large RCTs. Level of evidence: Level Basic research, controlled laboratory study.

As more veterinary clinics become specialized with the growth of the companion animal market, an increasing number of veterinary clinics perform orthopedic surgery and use orthopedic products, some of which are defective and have side effects. Thus, the present study aimed to prepare fundamental data for the revision and development of manufacturing standards for these products in order to prevent their side effects. We conducted a survey targeting veterinary clinics as consumers and medical device companies as suppliers. Veterinary clinics were surveyed via offline and online methods; 320 clinics that offered orthopedic surgery and approximately 4,000 veterinary clinics that were registered in the Korean Veterinary Medical Association were targeted, and 153 veterinary clinics responded to the survey. The survey for medical device companies, was performed online, targeting 29 companies; 14 companies responded. The number of side effects of orthopedic products was higher in animal orthopedic products than in those for human use. Many consumers tended to suspect that side effects were caused by product defects. To resolve side effects after using orthopedic products, consumers mostly underwent reoperation. Meanwhile, some severe cases proceeded to legal disputes. Similarly, medical device companies, or the suppliers, responded that most side effects occurred in veterinary orthopedic products and that product defects and mistakes in use were the causes. As for most of the follow-up actions for side effects, these companies either reported the issue to those in charge or analyzed and resolved the issues themselves. Therefore, to develop quality products, suppliers should be provided with clear standards for the production, and information disclosure and a report system for side effects should be particularly established to gain consumers' trust regarding the safety of these products.

Purpose : This study analysis of nursing interventions and core nursing interventions performed orthopedic surgery care unit. Method : The data were collected from 55 nurses of 4 general hospital from July. 10, 2002 to Aug. 30, 2002. The instrument for this study was the Korean translation of 486 nursing intervention classifications developed by McColskey & Bulechek in 2000. In the 486 nursing interventions 350 nursing interventions were selected 8 among the 10 more than 5 years working group in orthopedic surgery care unit. Self frequency checking performed by 350 nursing interventions were used secondary questionnaire In the orthopedic surgery care unit nurses. Results : 1. The most frequently used nursing interventions domains were "Physiological : basic" and then "Physiological: complex", "Health system" "Behavior", "Family", "Safety". 2. Orthopedic surgery care unit core nursing interventions were performed several times a day by 50% or more of orthopedic surgery care unit and this result were 4 of domain, 11 of class, 26 core nursing interventions. This core nursing interventions were 5 of "Physiological : basic", 17 of "Physiological: complex", 1 of "Safety", 3 of "Health system" and have no "Behavior", "Family". Conclusion : This study analyzed nursing intervention of orthopedics and reestablished nursing intervention concept and I hope this study will be helpful for the nurse to be a professional by applying this to actual clinic, for development in qualified nursing and for establishment nursing information system.

Lateral epicondylitis is one of the most common causes of elbow pain and has been known to be caused by degeneration of the extensor carpi radialis brevis (ECRB). Nonoperative treatment should be tried first in all patients, because it has been deemed highly successful; however only few prospective studies suggest that symptoms frequently was completely resolved. Operative treatment is indicated for recalcitrant pain after failed conservative treatment, which involves excision of the pathologic portion of the ECRB and results in a high degree of subjective relief and functional restoration. We will review the pathology of the lateral epicondylitis and operative and nonoperative treatment of lateral epicondylitis.

The midtarsal joint which consists of the talonavicular and calcaneocuboid joints lies transversely across the medial and lateral arches of the foot. Complete dislocation of this joint unassociated with fracture is extremely rare. A 36 year-old male who was injured by motor vehicle accident came to help for his left midfoot pain and deformity. We misdiagnosed as subtalar dislocation. Closed reduction was performed. We reviewed initial and post-reduction X-rays, and then we diagnosed as Chopart's dislocation. CT scan was taken; it showed fracture of the anterior process of the calcaneous.
