[Anatomy of the acromioclavicular and coracoclavicular region : Functional and clinical aspects].
The acromioclavicular (AC) joint connects the acromion with the lateral end of the clavicle and constitutes an important load-transmitting element between the upper extremity and the skeleton of the trunk. ⋯ Current clinical classification schemes fail to sufficiently include these multidirectional dislocating forces; however, they have to be considered when choosing the appropriate treatment modality. Thus, understanding the anatomical and functional context of the AC/CC region is essential for a sound management of AC joint injuries and fractures of the distal clavicle.

Acute and chronic acromioclavicular (AC) joint dislocation is frequently encountered in the routine clinical practice. This injury can lead to significant impairment of shoulder girdle function. Therapy based on the severity of injury is recommended to re-establish correct shoulder function. ⋯ Treatment of acute injuries is recommended within 1-3 weeks after trauma but there is no clear evidence of a cut-off for the presence of chronic injuries. Various surgical techniques have been described in the literature. This article presents an arthroscopically assisted technique that addresses both vertical and horizontal instability of the AC joint.

Case Reports
[Compartment syndrome caused by rhabdomyolysis in the context of pychogenic polydipsia.]
Psychogenic polydipsia leading to severe hyponatremia is well documented in the literature. This electrolyte disorder can result in encephalopathy, cerebral edema and epileptic seizures. Another rare effect is rhabdomyolysis with all its well known complications (e.g. renal failure, hyperkalemia and cardiac arrhythmia) and even resulting in compartment syndrome due to severe muscle edema. We present the case of a patient with severe hyponatremia caused by psychogenic polydipsia leading to rhabdomyolysis and compartment syndrome.

Review Multicenter Study Comparative Study
[Therapy of acute acromioclavicular joint instability : Meta-analysis of arthroscopic/minimally invasive versus open procedures].
A variety of surgical procedure are desrcibed for the treatment of acute acromioclavicular (AC-) joint injuries. Beside open techniques arthroscopic assisted procedures spread widely. Each surgical technique offers advantages and disadvantages, but none is currently accepted as a gold standard. Therefore, the study aims to review the evidence for arthroscopic and open surgical procedures in the treatment of acute AC joint instabilities. ⋯ There is insufficient evidence to inform the surgical management of acute AC joint instability. Due to inconsistent study designs there is no evidence for a general superiority of any of the open or arthroscopic procedures. Randomized, controlled studies are necessary to demonstrate whether arthroscopic techniques show a potential benefit in terms of a better functional outcome.

Pertrochanteric fractures are one of the most common injuries in the elderly and due to the demographic changes the incidence and importance of this fracture entity will even increase in the future. The dynamic hip screw (DHS) has been used as the gold standard implant in the treatment of pertrochanteric femoral fractures for many years but recent studies have shown that cephalomedullary nails have some advantages. Due to the high incidence, operative treatment of these fractures is part of the standard repertoire of trauma surgeons and this article therefore provides an overview of existing knowledge and new trends in the treatment of pertrochanteric femoral fractures.
