Akutes Kompartmentsyndrom der Extremitäten

Acute compartment syndrome of the extremities is a surgical emergency and a rapid diagnosis and immediate surgical treatment are essential for the outcome. The cause is an increase in the tissue pressure inside a muscle compartment enclosed by fasciae and the resulting disruption of microperfusion. This can have potentially disastrous consequences, such as loss of the extremity due to extensive tissue necrosis or a threat to life due to infectious complications. Although mostly triggered by trauma, a multitude of other causes can lead to the formation of a compartment syndrome, so that a basic knowledge of this condition is of great importance not only for trauma surgeons. This is particularly true because a timely treatment necessitates rapid diagnosis and evaluation of the indications. This article provides an overview of the underlying pathophysiology, the causes, the symptoms and the treatment of acute compartment syndrome

Treatment of parturition-induced rupture of pubic symphysis after spontaneous vaginal delivery

Parturition-induced rupture of pubic symphysis is an uncommon but severe complication of delivery. Characteristic symptoms are an immediate onset of suprapubic and/or sacroiliac pain within the first 24 hours postpartum, often accompanied by an audible crack. Diagnosis can be confirmed by imaging including X-ray, Magnet Resonance Imaging (MRI), and ultrasound. However, there is no consensus on the optimal therapy. Conservative treatment is predominantly used. It has been reported that, in cases of extreme symphyseal rupture with pelvic instability or persisting pain after conservative therapy, operative treatment achieves a successful outcome. In this report, we present a case of a twenty-year-old primigravida who developed suprapubic pain after a nonoperative vaginal birth with shoulder dystocia. A rupture of pubic symphysis with a gap of 60 mm was confirmed by means of X-ray and MRI. Simultaneously, other pelvic joint injuries could be excluded. Operative treatment by an open reduction and internal plate fixation yielded excellent results
