Acroparesthesia and Carpal Tunnel Syndrome: A Historical Perspective
submitted by printpok 16 minutes ago - Topic: Health
This article presents the history of acroparesthesia and its contribution to the discovery of idiopathic carpal tunnel syndrome (CTS). We used primary sources from the middle of the nineteenth century onward to show that the first short descriptions of patients with nocturnal and early morning paresthesias, numbness, pain, and weakness in the hands, without accompanying physical signs, were pub...



Carpal Tunnel Syndrome, Syndrome of Partial Thenar Atrophy, and W. Russell Brain: A Historical Perspective
submitted by printpok 17 minutes ago - Topic: Health
This article presents the history of the discovery of compression of the median nerve in the carpal tunnel without an identifiable cause as a distinct clinical entity. By analyzing primary sources, we show that, at the beginning of the twentieth century, physicians described patients with paresthesias and numbness in the hands, most prominent at night, accompanied by bilateral symmetrical atr...

Free Functioning Gracilis Transfer for Traumatic Brachial Plexus Injuries in Children
submitted by printpok 17 minutes ago - Topic: Health
To report our technique and experience with use of free functioning muscle transfer (FFMT) in reconstruction of traumatic brachial plexus injuries (BPIs) in children as well as its complications and outcomes. Twelve patients with complete BPI underwent FFMT for reconstruction between 2000 and 2012. Eight had single-stage gracilis transfer for restoration of elbow flexion, and 4 children had do...

Simulated Distal Interphalangeal Joint Fusion of the Index and Middle Fingers in 0° and 20° of Flexion: A Comparison of Grip Strength and Dexterity
submitted by printpok 17 minutes ago - Topic: Health
To evaluate dexterity and grip strength after simulated distal interphalangeal (DIP) joint fusion of the index and middle fingers in varying degrees of flexion. Forty-six right-handed subjects performed grip and dexterity testing using the Grooved Pegboard Test in positions of index finger 20° flexion or full extension, middle finger 20° flexion or full extension, and unrestricted index and m...

Expression of ghrelin and its receptor in rats after coronary artery ligation
submitted by takedake92 25 minutes ago - Topic: Biology
Ghrelin is a novel growth hormone-releasing peptide, which has been shown to exert beneficial effects on cardiac function and ventricular remodeling. The present study aimed to investigate the expression of ghrelin and the growth hormone (GH) secretagogue receptor 1a (GHSR-1a), and the association with cardiac remodeling in rats with myocardial infarction (MI). Twenty-four hours after ligation ...



Effect of Body Mass Index on Patients With Multiligamentous Knee Injuries
submitted by ciostan 33 minutes ago - Topic: Health
Our goal was to evaluate the impact of body mass index (BMI) on complications and associated injuries in patients undergoing surgical treatment for multiligamentous knee injuries (MLKIs). Over a period of 10 years, 126 MLKIs (123 patients) were included in the study. The inclusion criteria were (1) injury to 2 or more knee ligaments, multiligament repair and/or reconstruction performed by 1 of...

An Analysis of Technical Aspects of the Arthroscopic Bankart Procedure as Performed in the United States
submitted by ciostan 33 minutes ago - Topic: Health
The purpose of this study was to investigate the intersurgeon variation in technical aspects of performing an arthroscopic Bankart repair. A unique approach with experienced equipment representatives from 3 different arthroscopic companies was used. Experienced representatives were identified by DePuy Mitek, Smith Nephew, and Arthrex and filled out questionnaires on how their surgeons performed...


Arthroscopic Surgery for Synovial Chondromatosis of the Hip: A Systematic Review of Rates and Predisposing Factors for Recurrence
submitted by ciostan 33 minutes ago - Topic: Health
Synovial chondromatosis of the hip is a benign condition whereby pain and functional limitations occur due to numerous intra-articular osteochondral fragments produced by a metaplastic synovium. Recurrence not only worsens morbidity but may lead to malignant transformation. With reported recurrence rates as high as 22% by open surgical approaches and given the increasing use of hip arthroscopy ...

Topographic Variations in Biomechanical and Biochemical Properties in the Ankle Joint: An In Vitro Bovine Study Evaluating Native and Engineered Cartilage
submitted by ciostan 33 minutes ago - Topic: Health
The purposes of this study were to identify differences in the biomechanical and biochemical properties among the articulating surfaces of the ankle joint and to evaluate the functional and biological properties of engineered neocartilage generated using chondrocytes from different locations in the ankle joint. The properties of the different topographies within the ankle joint (tibial plafond,...


New Findings in Hip Capsular Anatomy: Dimensions of Capsular Thickness and Pericapsular Contributions
submitted by ciostan 33 minutes ago - Topic: Health
The purpose of this investigation was to provide a detailed description of the anatomy of the hip capsule and pericapsular structures. Dissections were performed on 11 nonpaired, fresh-frozen cadaveric hips by 2 independent observers: 1 fellowship-trained orthopaedic total joint surgeon and 1 chief orthopaedic surgery resident. Documentation of capsular thickness, origins, insertions, and attac...

Arthroscopic Femoral Neck Osteoplasty in Slipped Capital Femoral Epiphysis
submitted by ciostan 33 minutes ago - Topic: Health
To investigate the outcomes of arthroscopic femoral neck osteoplasty in patients with slipped capital femoral epiphysis (SCFE)–related impingement. We retrospectively reviewed 37 consecutive patients (40 hips; 19 male and 18 female patients; age range, 10 to 19 years) with SCFE who underwent hip arthroscopy for femoral neck osteoplasty over a 4-year period. Six hips were excluded because of ...

Fruit consumption and seed dispersal by birds in native vs. ex situ individuals of the endangered Chinese yew, Taxus chinensis
submitted by iic 35 minutes ago - Topic: Biology
The conservation success of endangered trees may depend on re-establishing or replacing the mutualisms that were important in their native habitats. In this study, we quantified avian frugivore diversity on individuals of the endangered Chinese yew (Taxus chinensis) in a botanical garden and at a natural site. We found that frugivore species diversity was lower in the botanical garden than in t...
