Muscle injuries are the most frequent sport injuries in athletes. In addition to a thorough clinical examination and the history of the trauma mechanism, imaging modalities are required to correctly classify the injury and plan the future treatment and rehabilitation. The two major modalities are ultrasound and magnet resonance imaging (MRI). This article aims to give a comprehensive overview on the possibilities and limitations of MRI imaging in musculoskeletal injuries as well as insight into current development, classifications and technologies.

Abdominal trauma represents the leading cause of haemorrhagic shock in the severely injured patient and is associated with high mortality and morbidity rates. The trauma surgeon has a central role in the multidisciplinary team addressing the specific diagnostic and therapeutic needs of patients with abdominal trauma. ⋯ Another key development is the introduction of the damage control concept for the care of patients with abdominal trauma. The present manuscript comprises a review of the current management of abdominal trauma with an emphasis on diagnostic and therapeutic innovations.

Falling on the outstretched hand is a common trauma mechanism. In contrast to fractures of the distal radius, which usually are diagnosed on plain film radiographs, identifying wrist injuries requires further diagnostic methods, e.g., MRI or CT. ⋯ MRI shows a high reliability in the diagnosis of scaphoid fractures and the America College of Radiology recommends MRI as method of choice after X-ray images have been made. In the diagnosis of ligament and discoid lesions, MR arthrography (MRA) using intraarticular contrast agent has considerably higher accuracy than i.v.-enhanced and especially unenhanced MRI.

In addition to ultrasound and conventional x-ray, magnetic resonance imaging (MRI) plays an important role in the visualization of lesions of the knee. It allows the orthopaedic surgeon to safely detect ruptures of the cruciate ligaments, the meniscus, osteochondral lesions and other ligamentary structures such as the collateral ligaments and the medial patellofemoral ligament (MPFL). ⋯ This articles aims to give the reader a comprehensive overview on current concepts and techniques in the use of MRI for lesions of the knee. It focuses on patellar dislocations, where MRI plays a dominant role in supporting decision making for the best therapeutic strategy.
