Summary: In front of a muscle injury, first thing must imperatively be interrogation and complete physical examination that will mostly be followed by ultrasound. The treatment is based on fight against deficiencies (pain, shortening of articular amplitudes, decrease of muscle strength) and on restoration of proprioception and stability qualities. The notion of “directed traction” and muscle strengthening is essential because only that will allow a good healing. Rehabilitation principles are globally the same whatever the injury''s seriousness is, the only variations are exercises delays and intensity. Indeed, in every case, rehabilitation will be always adapted to physical examination and will respect pain threshold. The duration of sport rest is in general 1 week for a minor injury and until 6 weeks for a serious one but in certain cases, these delays could be lengthened. [Copyright &y& Elsevier]

Abstract: The use of arthroscopy in the management of intra-articular fractures of the distal radius has become established over the last ten years, but the operative technique is not yet standardised. We report our experience with this technique and give a stage by stage description of the operative procedure. The arthroscopic part of the procedure consists firstly of an evaluation of the bony, cartilaginous and ligamentous injuries and secondly direct visual control of the reduction. The choice of bone fixation depends on the individual preferences of the surgeon but may be influenced by the configuration of the fracture. A literature review reiterates the advantages of arthroscopic assistance in managing these fractures without revealing any disadvantages. However, mastery of the arthroscopic techniques is vital before the full advantages of this type of management can be realised. [Copyright &y& Elsevier]

Résumé: Les traumatismes des métacarpiens représentent environ un tiers des lésions de la main chez l’enfant et l’adolescent. Seule une bonne connaissance du potentiel de croissance local et des particularités anatomiques permet de prendre en charge ces fractures et luxations, qui sont le plus souvent d’évolution favorable. Vingt pour cent d’entres elles nécessitent une réduction, et le recours à la stabilisation chirurgicale est rare. Les différentes lésions sont abordées en précisant les modalités diagnostiques, les principes thérapeutiques, les pièges à éviter et les complications éventuelles. [ABSTRACT FROM AUTHOR]
