Intramedullary nailing is the "gold standard" treatment modality of diaphyseal fractures of the tibia. However, when the same method is used for extra-articular fractures of the proximal tibia, various problems may occur, like malalignment, loss of reduction, and non-union. The objective of the present biomechanical study was to compare the stability of six tibial nails when these are used for the treatment of unstable, extra-articular, proximal tibial fractures. ⋯ Solid nails provide more rigidity compared to cannulated ones, and the maximum number of proximal screws in all possible directions should be used in order to achieve maximum stability.

Although cardiopulmonary exercise (CPX) test is an essential tool for the assessment of functional capacity in athletes, limited information exists regarding the cardiorespiratory efficiency in young elite volleyball players. The main objective of the present study was to determine the maximal oxygen uptake (VO2max) and ventilatory anaerobic threshold (VT) during the CPX test in young male and female volleyball players. Moreover, to describe the behavior of the novel cardiorespiratory optimal point (COP) index and to assess its association with VO2max and VT. ⋯ The novel submaximal cardiorespiratory index of COP does not seem to be associated with the traditional aerobic capacity indices in athletes such as VO2max and VT. Thus, it probably constitutes a separate parameter that needs to be further evaluated regarding its significance both in clinical evaluation and sports performance assessment of athletes.

Arthroscopic meniscus surgery can lead to pain at various levels. In this study, we aimed to compare, in patients undergoing arthroscopic meniscectomy under spinal anesthesia, the efficacy of the combination of magnesium sulfate and dexmedetomidine with local anesthetics administered intraarticularly for postoperative pain management Methods: This prospective, randomized, controlled, double-blind study comprised of 52 patients who were randomly assigned into two groups depending on the combination injected intraarticularly at the end of the procedure: bupivacaine and dexmedetomidine (group D) or bupivacaine and magnesium sulfate (group M). Perioperative data, postoperative visual analog scale (VAS) scores, and total analgesic consumption were recorded. ⋯ Both intraarticular dexmedetomidine and magnesium sulfate, in combination with bupivacaine, have similar effects on reducing postoperative pain in arthroscopic knee surgery.
