[Treatment strategy for an unstable chest wall after cardiopulmonary resuscitation]. / Versorgungsstrategie des instabilen Thorax nach kardiopulmonaler Reanimation.

Every year ca. 60,000 people in Germany undergo cardiopulmonary resuscitation (CPR). The two most frequent underlying causes are of cardiopulmonary and traumatic origin. According to the current CPR guidelines chest compressions should be performed in the middle of the sternum with a pressure frequency of 100-120/min and to a depth of 5-6 cm. In contrast to trauma patients where different injury patterns can arise depending on the accident mechanism, both the type of trauma and the injury pattern are similar in patients after CPR due to repetitive thorax compression. It is known that an early reconstruction of the thoracic wall and the restoration of the physiological breathing mechanics in trauma patients with unstable thoracic injuries reduce the rates of pneumonia and weaning failure and shorten the length of stay in the intensive care unit. As a result, it is increasingly being propagated that an unstable thoracic injury as a result of CPR should also be subjected to surgical treatment as soon as possible. In the hospital of the authors an algorithm was formulated based on clinical experience and the underlying evidence in a traumatological context and a surgical treatment strategy was designed, which is presented and discussed taking the available evidence into account.

[Osteosynthesis of Weber B ankle fractures using the one-third tubular plate and refixation of the syndesmosis]. / Osteosynthese von Weber-B-Sprunggelenkfrakturen mit der Drittelrohrplatte und Syndesmosenrekonstruktion.

OBJECTIVE: Anatomical reconstruction and recovery to complete range of function of the upper ankle joint. Therefore, the most stable but least invasive osteosynthesis is required to enable the patient early functional mobilization. INDICATION: Supination and pronation fracture with luxation mechanism of the upper ankle joint with or without rupture of the syndesmosis. Open fracture of the distal fibula including displaced and instable fractures. CONTRAINDICATION: Severe peripheral arterial occlusive disease; contaminated open fractures (≥ 2nd degree); pediatric fractures with open epiphyseal plate. SURGICAL TECHNIQUE: Supine position with ipsilateral slightly elevated hip and knee. Incision of about 8 cm length along the dorsal edge of the distal fibula. When reaching the lateral malleolus, a slight ventral angulation is necessary. Open reduction through this posterolateral approach. Secure the reposition using an interfragmentary lag screw and anatomically adjusted third tubular plate. Followed by a revision of the syndesmosis and transfixation using a tricortical position screw. POSTOPERATIVE MANAGEMENT: Mobilization on day 1 after surgery with reduced weight-bearing when position screw is not applied; when position screw is implanted with ground contact for 6 weeks. Removal of position screw under local anesthesia after 6 weeks and pain-controlled full weight-bearing. Removal of metal after 1.5 years. RESULTS: Open reduction using the third tubular plate and an interfragmentary lag screw through a dorsolateral approach used in 90 % of all Weber B fractures in our clinic. Additional revision of a ruptured syndesmosis performed in 70 % and transfixation through a position screw in 40 %. Persisting instability in the upper ankle joint significantly reduced after surgical treatment compared to a conservative approach. Revisions necessary in 3.7 % of patients and pseudarthrosis diagnosed in 0.9 %. It has been shown that the preoperative x-ray and clinical examination is limited in detecting a ruptured syndesmosis.
