Medial clavicle fractures and injuries to the sternoclavicular joint are rare injuries but can have life-threatening consequences. There are no standardized treatment algorithms or guidelines for the diagnostics and treatment. This article provides an overview of the individual topographies as well as the conservative and surgical treatment strategies.Conservative treatment is preferred for medial clavicle fractures. The indications for surgical treatment are variable but this is frequently carried out if there is a fracture displacement > 1 cm or 1 shaft width and high functional demands. In the case of accompanying injuries to neurovascular structures, an open fracture or the threat of perforation of the skin, surgical treatment is mandatory. Open reduction and internal fixation using (locking) plates is currently the preferred form of treatment.In the case of posterior dislocation of the sternoclavicular joint, an immediate closed reduction must be attempted with the patient under analgosedation and with emergency treatment on standby. This temporal urgency does not exist for anterior and superior dislocations. Surgical treatment is indicated in cases of unsuccessful reduction, persistent symptomatic instability or injuries of the neurovascular bundle. From a multitude of treatment options, arthrodesis with suture cerclage has shown good results. Tendon grafts as well as special hook plates are increasingly being used due to better biomechanical qualities. The surgical treatment of combined injuries is determined by the individual injury pattern.Despite the variety of treatment strategies, the long-term outcome has consistently been positively described.

With up to 50 incidents per 100,000 inhabitants, Achilles tendon ruptures are among the most frequent tendon injuries encountered in orthopedics and trauma surgery. Apart from high-risk forms of sport, degenerative processes are primarily responsible for weakening and ultimately rupture. In addition to assessing the typical clinical signs with inability to perform powerful plantar flexion, the diagnostics include easy to earn examination techniques, such as the Thompson test and ultrasound as the imaging gold standard. Conservative and surgical treatment are available depending on the constitution, age and requirements of the patient. The latter option is divided into conventional open, minimally invasive or percutaneous procedures. Good to very good results can be expected regardless of the form of treatment, provided that early functional rehabilitation is carried out. The average rerupture rate is 5% and the return to sport rate is around 80%.

Introduction: The primary goal is preservation of the affected extremity, which can be associated with limitations in tasks relevant for daily life and a distorted body image caused by the original trauma. Therefore, a secondary goal is to reduce the trauma sequelae.

Results: For an esthetic outcome the choice of flap surgery is crucial. Factors such as tissue thickness, skin color, and hair covering need to be considered. The flap should blend seamlessly with the tissue surrounding the defect. The localization and closure of the defect are also important. The flaps undergo vascular, lymphatic and trophic postoperative changes caused by the so-called autonomization. Measures, such as compression therapy reshape the microcirculation and result in volume reduction of the transplant. It is important to preoperatively educate patients about this process. After completion of the conditioning surgical thinning procedures are available for persistent unattractive results, e.g., open surgical and liposuction techniques.

Conclusion: Microsurgical defect coverage of traumatic skin and soft tissue defects is a compromise between limb preservation and functionality. In cases of missing local soft tissue, secure closure of the defect should be prioritized but initial esthetic considerations should also influence the choice of tissue transplant. Patients should be informed early about the development of the flap surgery and undergo postoperative compression therapy for conditioning. Secondary operative corrections are also possible.

Background: The occurrence of infections has always been feared in all surgical disciplines. Plastic reconstructive surgery faces the challenge of treating infection-related defects on a patient-specific basis, which requires a multidisciplinary treatment concept. Satisfactory treatment success can only be achieved through radical debridement for infection cleansing, optimization of the perfusion situation paired with targeted anti-infective treatment and, if necessary, with soft tissue reconstruction by plastic surgery.

Objective: This article presents the current possibilities of plastic and reconstructive surgery with respect to the reconstruction of infection-related defects.

Material and methods: Proven and reliable strategies are presented and supplemented by promising experimental approaches.

Results: Due to the often multilayered defect situation caused by infections, from the epidermis to cancellous bone, the entire armamentarium of plastic and reconstructive surgery is used for reconstruction.

Conclusion: The early involvement of plastic surgery in the treatment of infections and the interdisciplinary and multimodal treatment approach have proven their worth in the treatment of complex infection situations.

Due to demographic changes, fractures and subsequently delayed fracture healing as well as pseudarthrosis of the proximal femur are on the increase. In the acute fracture situation, a load-stable treatment with an intramedullary implant (cephalomedullary nail) is generally sought. To date, there is no uniform consensus on the optimal treatment for complicated cases. The aim of this study was to evaluate the clinical and radiological outcome after revision of pseudarthrosis using a 95° blade plate in aseptic proximal femoral pseudarthrosis and to identify the specifications of blade plate treatment.The retrospective study design was used to evaluate data, some of which were prospectively collected. The study period covered January 2010 to December 2020 and 22 patients (10 women, 12 men) with an average age of 59 years were included in this single-center study. All patients showed pseudarthrosis after a femoral fracture type AO 31 A1-A3 or proximal femoral fracture type AO 32 A-C. Clinical and radiological follow-up were performed after 3, 6 and 12 months. Functional outcomes were assessed using the modified Harris hip score (mHHS), the numerical rating scale (NRS) and the short form health survey (SF-12).The postoperative radiological results after reosteosynthesis using a blade plate showed good results and 86.4% of the patient population were healed during the observation period. Pseudarthrosis persisted in four patients and was surgically revised.The functional results showed good results on average, albeit with a high dispersion of 17-91 points in the mHHS. The SF-12 averaged 42.6 (±10.4) points and the psychological score 49.4 (±9.6) points. The postoperative pain level was low both at rest and under stress.It was shown that reosteosynthesis with a blade plate is a surgically demanding but effective treatment option with a low potential for infection and safe bone consolidation, especially for the correction of high-grade axial deviation or varus malalignment.

Background: The precise analysis of the injured structures requiring reconstruction in complex wound defects is a prerequisite for successful restoration.

Objective: The fundamental reconstructive strategies for soft tissue defects of the extremities including injuries to vessels, nerves and burn wounds in the context of the acute and post-acute trauma phases are presented.

Material and methods: The different phases of soft tissue reconstruction are described. Recommendations for action with respect to the reconstruction of the functional structures are described. Two clinical case examples illustrate the approach.

Results: The acute reconstruction phase is defined as the period 0-72 h after the traumatic event and includes surgical debridement, primary reconstruction of nerves and vessels using interpositional grafts if necessary and temporary soft tissue reconstruction. Combined thermomechanical trauma requires early debridement combined with internal fixation of open fractures. In the post-acute reconstruction phase, which is generally defined as a period of up to 6 weeks after the traumatic event, definitive soft tissue reconstruction is performed. In the case of long reinnervation distances, nerve transfer or motor replacement plastic surgery is performed in the post-acute phase.

Conclusion: The reconstruction of soft tissue after trauma necessitates a stage-dependent approach. In the acute phase procedures aim at the immediate preservation of the limb. In the post-acute phase, definitive soft tissue reconstruction is performed to enable maximum functional preservation. Combined thermomechanical injuries require early surgical treatment in order to prevent infections.

Secondary reconstruction in trauma surgery is crucial for restoring both functional and esthetic results in patients with complex defects. Established reconstructive techniques in plastic surgery offer a wide range of options for an effective treatment. This applies not only to covering large defects with free flaps but especially also for the functional reconstruction of bony, neural and musculotendinous impairments. Advances in the fields of microsurgery and 3D printing show innovative approaches to further improve the therapeutic options. A multidisciplinary approach, requiring close collaboration between trauma and plastic surgeons, is necessary to optimize treatment plans and outcomes. The effective management of complications and qualified postoperative care are essential for the success of reconstructive measures.

The challenge in treating traumatic hemipelvectomy is the dynamics of the complex and life-threatening consequences of the injury. These include skin and soft tissue defects, osseous, neural and vascular injuries as well as the subsequent hemostatic derangement and organ dysfunction as part of the shock process. The treatment requires rapid and targeted decisions to save the patient's life. In this particular case a 34-year-old farmer was trapped between a wheeled loader and a stationary trailer. Upon arrival at the hospital the patient was in a state of hemorrhagic shock with accompanying acute traumatic coagulopathy and a grade III open pelvic trauma with complete ischemia of the left leg and a bladder injury. After performing emergency surgery and a two-stage approach for pelvic stabilization the patient's condition deteriorated up to multiorgan failure, necessitating left-sided hemipelvectomy as an immediate life-saving salvage procedure. In the further course multiple revision surgeries and plastic reconstructions due to wound infections and the presence of skin and soft tissue damage were required. Due to the rare confrontation with this type of injury in everyday practice and the absence of a universal treatment algorithm, the following case report is intended to contribute to a better understanding of the treatment and to illustrate the coherent interactions of the individual organ systems affected.
