All-Arthroscopic Foveal Triangular Fibrocartilage Complex Tendon Reconstruction.

Background In symptomatic chronic injury of ulnar-sided tear of the triangular fibrocartilage complex, reconstruction techniques involving foveal reconstruction with palmaris longus tendon graft using the method described by Bain have been described with good outcomes. Description of Technique With increasing popularity of wrist arthroscopy to address various wrist pathologies, we present our technique of arthroscopic foveal reconstruction. We also include a step-by-step description of the procedure with illustrations, with aims to aid surgeons in executing it Conclusion Unlike other arthroscopic techniques described, this involves single osseous ulnar tunnel and performed completely arthroscopically, allowing an end result similar to Bain's open technique.

Symptomatic Radial-Sided Tears of the Triangular Fibrocartilage Complex: An All-Arthroscopic Repair Using Bone Anchors.

Radial-sided tears of the triangular fibrocartilage, though uncommon, can still be a reason for ulnar-sided wrist pain, and, at times, instability of the distal radioulnar joint. Historically, it has been believed that because of the paucity of vascularity along the radial edge of the triangular fibrocartilage complex (TFCC), any form of repair will not lead to healing, thus stating it to be an exercise in futility. Current literature deftly argues against this previously prevailing concept and supports the need of repair in case of symptomatic radial-sided TFCC tears. In our study, we describe an all-arthroscopic technique of repairing radial-sided tears using a bone anchor which can be a fast and simple procedure in the hands of an orthopaedic or hand surgeon trained in arthroscopy. This technique also circumvents the risk of injuring the superficial radial nerve and other radial-sided structures which are stated complications of the current arthroscopic repairs.

Association of reported fish intake and supplementation status with the omega-3 index.

BACKGROUND: An Omega-3 Index (O3I; EPA+DHA as a % of erythrocyte total fatty acids) in the desirable range (8%-12%) has been associated with improved heart and brain health. OBJECTIVE: To determine the combination of fish intake and supplement use that is associated with an O3I of >8%. DESIGN: Two cross-sectional studies comparing the O3I to EPA+DHA/fish intake. PARTICIPANTS/SETTING: The first study included 28 individuals and assessed their fish and EPA+DHA intake using both a validated triple-pass 24-hr recall dietary survey and a single fish-intake question. The second study used de-identified data from 3,458 adults (84% from US) who self-tested their O3I and answered questions about their fish intake and supplement use. STATISTICAL ANALYSES PERFORMED: Study 1, chi-squared, one-way ANOVA, and Pearson correlations were computed. In Study 2, multi-variable regression models were used to predict O3I levels from reported fish/supplement intakes. RESULTS: The mean ±â€¯SD O3I was 4.87 ±â€¯1.32%, and 5.99 ±â€¯2.29% in the first and second studies, respectively. Both studies showed that for every increase in fish intake category the O3I increased by 0.50-0.65% (p < 0.0001). In the second study, about half of the population was taking omega-3 supplements, 32% reported no fish intake and 17% reported eating fish >2 times per week. Taking an EPA+DHA supplement increased the O3I by 2.2% (p < 0.0001). The odds of having an O3I of ≥8% were 44% in the highest intake group (≥3 servings/week and supplementation) and 2% in the lowest intake group (no fish intake or supplementation); and in those consuming 2 fish meals per week but not taking supplements (as per recommendations), 10%. CONCLUSIONS: Current AHA recommendations are unlikely to produce a desirable O3I. Consuming at least 3 fish servings per week plus taking an EPA+DHA supplement markedly increases the likelihood of achieving this target level.

Survey of the erythrocyte EPA+DHA levels in the heart attack/stroke belt.

BACKGROUND: The Omega-3 Index (O3I; erythrocyte EPA+DHA as a percent of total fatty acids) is inversely related to risk for cardiovascular disease (CVD). The cardioprotective target O3I is 8%-12%. O3I levels in American regions with high CVD risk are poorly characterized. PURPOSE: To determine the O3I in individuals participating in a Seafood Nutrition Partnership (SNP) survey in seven US cities in the CVD "belt." METHODS: Fingerstick blood samples were analyzed for the O3I. RESULTS: The SNP cohort (n = 2177) had a mean (SD) O3I of 4.42% (1.12%). Only 1.2% were in the desirable range, whereas 42% had an undesirable (<4%) O3I. The mean (SD) O3I in a subset of 772 SNP subjects who were matched for age and sex with the Framingham study was 4.6% (1.2%) compared 5.3% (1.6%) in the Framingham cohort (p < 0.0001). CONCLUSIONS: Individuals in the CVD "belt" had relatively low O3I levels. Since in other settings, a low O3I is associated with increased risk for CVD, this may be one factor contributing to the higher risk for CVD in this region of the US.
