First Carpometacarpal Joint Instability: Dorsal Ligament Reconstruction.

The first carpometacarpal (CMC-I) joint has an elaborate ligamentous support. Recent evidence has demonstrated that the dorsal ligament group is imperative for joint stability and that CMC-I joint instability may occur as a consequence of trauma and ligamentous laxity, and other conditions, with possible CMC-I subluxation and the development of osteoarthritis. Although various surgical techniques have been introduced for the treatment of ligamentous CMC-I instability, the Eaton-Littler reconstruction has been regarded as the gold standard.

Mixed tocopherols have a stronger inhibitory effect on lipid peroxidation than alpha-tocopherol alone.

Intake of vitamin E with food (mixed tocopherols) has been found to counteract the development of atherosclerotic cardiovascular disease, whereas intake of large amounts of pure alpha-tocopherol has shown only a slight or no effect in clinical studies. This study was designed to investigate the effects of alpha-tocopherol alone and a mixed tocopherol preparation (gamma-, delta-, and alpha-tocopherol) on hydrogen peroxide-induced lipid peroxidation in human erythrocytes. Erythrocytes were incubated with different concentrations of alpha-tocopherol or mixed tocopherols and then exposed to hydrogen peroxide.

Functional outcome of anterior cruciate ligament reconstruction in recreational and competitive athletes.

The aim of this study was to compare the outcome after anterior cruciate ligament reconstruction in recreational and competitive athletes, with a minimum follow-up of two years. Forty-nine patients (24 males and 25 females) who, at the time of the index injury, were classified as recreational athletes (Tegner level 2-5) were compared with 226 patients (61 females and 165 males) who, at the time of the index injury, were classified as competitive athletes (Tegner level 9-10). At the follow-up, no significant differences were found between the study groups in terms of the Lysholm score, IKDC evaluation system, one-leg-hop test, KT-1000 laxity measurements, anterior knee pain and the patients' subjective evaluation of the results.
