The Surgical Treatment of a Bimalleolar Ankle Fracture - Tips and Tricks.

The ankle fracture - the most common fracture of the lower extremities - is usually due to pro- and supination trauma and is commonly challenging for junior doctors of orthopaedics and traumatology. To accomplish sufficient surgical results, it is necessary to have surgical experience, not only because of the surrounding fragile soft tissue, but also due to the specific anatomical structures surrounding the ankle joint and the postsurgical biomechanical stress to osteosynthesis. In the following video, the most relevant steps of surgery as well as some useful tips and tricks are mentioned.

Improved gait parameters following surgical revascularization in patients with intermittent claudication.

Objective: Intermittent claudication (IC) is known to be associated with impaired gait parameters, with a higher incidence of falls and higher oxygen consumption due to uneconomic walking. However, the influence of arterial disobliteration in patients with IC on their gait pattern has rarely been investigated to date. The aim of this study was to examine the gait patterns before and after inflow revascularization by surgical disobliteration of pelvic and inguinal arteries (ie, common iliac artery, external iliac artery, common femoral artery, profound femoral artery, superficial femoral artery) in IC patients.

Insufficiency Fractures vs. Low-Energy Pelvic Ring Fractures - Epidemiological, Diagnostic and Therapeutic Characteristics of Fragility Fractures of the Pelvic Ring.

Background: Fragility fractures of the pelvis (FFP) encompass two fracture entities: fracture after low-energy trauma and insufficiency fracture without trauma. It is unclear whether the two subgroups differ in terms of diagnosis and therapy. The aim of this retrospective study was to evaluate insufficiency fractures with regard to defined parameters and to compare specific parameters with the fractures after low-energy trauma.

Epidemiological and Therapeutic Developments in Pelvic Ring Fractures Type C from 2004 to 2014 - a Retrospective Data Analysis of 2,042 Patients in the German Pelvic Register (DGU).

Background: Pelvic ring fractures type C present a special challenge due to their high instability, the possible accompanying injuries and the high mortality rate of up to 18.9%. The aim of this retrospective analysis was to use the data from the DGU pelvic register to identify changes in the epidemiology and therapy for type C pelvic ring fractures between 2004 and 2014.

[Triangular minimally invasive spinopelvic stabilization for type C pelvic fractures according to AO/OTA and type IV according to FFP].

Introduction: Spinopelvic instability is common in type IV fragility fractures of the pelvic ring (FFP) and type C traumatic pelvic fractures. This results in the indications for operative stabilization using a spinopelvic support. Due to the variety of surgical techniques for spinopelvic support it is unclear what importance a minimally invasive spinopelvic screw-rod osteosynthesis can have.

Modified therapy concepts for fragility fractures of the pelvis after additional MRI.

Background: Fractures of the pelvic ring in elderly patients have increased in frequency over time. These injuries are associated with a high morbidity and have a socio-economic impact. The diagnostic procedures and their influence of therapy decisions are still controversial.

Fragility Fractures of the Pelvic Ring - Does the Evidence of Oedema Lead us to More Surgeries?

Introduction: The choice of therapy for fragility fractures of the pelvis (FFP) is largely determined by the diagnosed fracture morphology. It is now unclear whether the change in diagnostic options - sensitive detection of fracture oedema in the sacrum using MRI and dual-energy computed tomography (DECT) - has an impact on the therapeutic consequences. The aim of this retrospective study was therefore to evaluate the change in the diagnostics used and the resulting therapy regimen in our patient population.

[Internal meniscus resections do not affect anterior knee joint stability].

Background: Meniscus injuries lead to increased knee joint instability. Currently, however, it is unclear whether a relevant medial meniscus part resection leads to an increased ventral tibia translation with intact anterior cruciate ligament. The aim of our study was therefore to clinically examine the stabilizer function of at least 30% resected medial meniscus for anterior tibial translation.

Surgical Reconstruction Options in Chronic Distal Biceps Tendon Ruptures - Case Report and Literature Review.

Introduction: Chronic distal biceps tendon ruptures are rare and conservative or operative treatment options are suitable. There is a consensus in the literature in case of acute traumatic ruptures the operative refixation should be preferred. Disagreement exists in the best way of care of old ruptures (> 4 weeks) of distal biceps tendon.

Dual-energy CT as an innovative method for diagnosing fragility fractures of the pelvic ring: a retrospective comparison with MRI as the gold standard.

Introduction: As the average age of society increases, so does the number of cases of fragility fractures of the pelvis (FFP). Magnetic resonance imaging (MRI) can visualise associated oedema and is thus the gold standard for diagnosing such fractures. MRI, however, is costly, not always available, and involves certain exclusion criteria.

Magnetic Resonance Imaging in Pelvic Fractures - Part 2: Gaining Information and Clinical Therapeutic Relevance.

Background: Magnetic resonance and computed tomography (MRI, CT) has been known to compare the sensitivity for the detection of pelvic fractures with others. It is unclear whether MRI imaging beyond CT leads to therapy change. The aim of our study is to determine the information gained from MRI in the diagnosis of pelvic fractures and to reduce the effects on the form of therapy.

Magnetic Resonance Imaging in Pelvic Fractures - Part 1: Which Criteria Lead Us to Supplementary MRI Diagnostics?

Introduction: Isolated pelvic fractures are relatively rare with an incidence of 3 - 6% of all fractures, but their incidence in polytraumatized individuals increases to 25%. The S3 guideline Polytrauma gives a clear recommendation for diagnostics by means of pelvic radiography (X-ray) and computed tomography (CT). A recommendation for the diagnosis by means of magnetic resonance tomography (MRI) especially in patients with low energetic/missing trauma does not currently exist.

Initial Harm Reduction by N-Acetylcysteine Alleviates Cartilage Degeneration after Blunt Single-Impact Cartilage Trauma in Vivo.

Joint injuries are highly associated with the development of post-traumatic osteoarthritis. Previous studies revealed cell- and matrix-protective effects of N-acetylcysteine (NAC) after ex vivo cartilage trauma, while chondroanabolic stimulation with bone morphogenetic protein 7 (BMP7) enhanced type II collagen (COL2) expression. Here, as a next step, we investigated the combined and individual efficacy of intra-articular antioxidative and chondroanabolic treatment in a rabbit in vivo cartilage trauma model.

Fragility Fractures of the Pelvis Classification: A Multicenter Assessment of the Intra-Rater and Inter-Rater Reliabilities and Percentage of Agreement.

Background: The fragility fractures of the pelvis (FFP) classification was established to address the specific fracture morphology and dynamic instability in the elderly. Although this system is frequently used, data on the intra-rater and inter-rater reliabilities are lacking.

Methods: Six experienced and 6 inexperienced surgeons and 1 surgeon trained by the originator of the FFP classification ("gold standard") each used the FFP classification 3 times to grade the computed tomography (CT) scans of 60 patients from 6 hospitals.

Age and "general health"-beside fracture classification-affect the therapeutic decision for geriatric pelvic ring fractures: a German pelvic injury register study.

Purpose: Pelvic ring fractures in the elderly gain increasing importance. Nonetheless, data on factors influencing treatment decision in relation to fracture classification, age, and the resulting treatment are still rare.

Methods: Prospectively collected data of the German Pelvic Injury Registry from patients aged over 65 years with a pelvic ring fracture were evaluated retrospectively.

Avulsion Fractures of the Ischial Tuberosity and Resulting Ischiofemoral Impingement - a Case Report with Literature Review.

Introduction: Apophyseal avulsion fractures of the ischial tuberosity are rare injuries and therefore often not diagnosed in a timely manner. Healing may then result in massive hypertrophic ischial tuberosity. This can cause ischiofemoral impingement symptoms.

Diagnostic Accuracy of Fluoroscopy, Radiography, and Computed Tomography in Detecting Cement Leakage in Kyphoplasty.

Purpose:  Cement leakage is a typical complication of kyphoplasty for vertebral fractures. It is unclear if cement application intraoperatively can be improved by using other techniques of visualization and which kind of postoperative imaging should be recommended to detect cement extravasation accurately.

Objective:  To compare the rates of cement leakage detected by intraoperative fluoroscopy, postoperative radiography, and postoperative computed tomography (CT) in a retrospective study.

[Vertebral Body Height after Balloon Kyphoplasty vs. Radiofrequency Kyphoplasty].

Background: Kyphoplasty is used to alleviate pain and to restore the initial height of osteoporotic vertebral fractures (OVF). One of the most recent procedures is radiofrequency-targeted vertebral augmentation (RFTVA). We investigated whether restoration with this method is similar and as adequate as with the established procedure of balloon kyphoplasty (BKP), as assessed by the anatomical height of the vertebral body.

Dual Energy Computed Tomography in Musculoskeletal Imaging, with Focus on Fragility Fractures of the Pelvis.

Dual energy computed tomography (DECT) is a constantly evolving technology, which opens up new diagnostic possibilities. It is particularly valuable for musculoskeletal (MSK) imaging. Due to the lack of recognition and availability of dual energy scanners, routine use is only established in a few centres.

[The Relevance of Surgeon-performed Ultrasound For the Detection of Acute Appendicitis: a Review of the Literature and a Practical Diagnostic Algorithm].

The relevance of ultrasound (US) in diagnosing acute appendicitis is controversial. The validity of US in comparison with other imaging techniques, such as computed tomography (CT) and magnetic resonance imaging (MRI), is unclear, as is the difference between surgeon-performed ultrasound (SPUS) and radiologist-performed ultrasound (RPUS). On the basis of a review of current literature, our study aimed to develop a US-based algorithm to simplify the choice between additional diagnostic measures and surgery.

Striking a new path in reducing cartilage breakdown: combination of antioxidative therapy and chondroanabolic stimulation after blunt cartilage trauma.

Cartilage injury can trigger crucial pathomechanisms, including excessive cell death and expression of matrix-destructive enzymes, which contribute to the progression of a post-traumatic osteoarthritis (PTOA). With the intent to create a novel treatment strategy for alleviating trauma-induced cartilage damage, we complemented a promising antioxidative approach based on cell and chondroprotective N-acetyl cysteine (NAC) by chondroanabolic stimulation. Overall, three potential pro-anabolic growth factors - IGF-1, BMP7 and FGF18 - were tested comparatively with and without NAC in an ex vivo human cartilage trauma-model.

The role of whole-body computed tomography in the diagnosis of thoracic injuries in severely injured patients - a retrospective multi-centre study based on the trauma registry of the German trauma society (TraumaRegister DGU).

Background: Thoracic injuries are a leading cause of death in polytrauma patients. Early diagnosis and treatment are of paramount importance. Whole-body computed tomography (WBCT) has largely replaced traditional imaging techniques such as conventional radiographs and focused computed tomography (CT) as diagnostic tools in severely injured patients.

[Pathogen Spectrum of Complex Wounds in Germany from War Zones].

Treatment of the injured from war zones with wounds with multi-resistant pathogens is becoming more common in Germany, especially in German Armed Forces Hospitals. In most cases, the pre-treatment of these patients has been inadequate and they have a high load of rare pathogens. In Germany, hospitals have to evaluate these pathogens by law.
