[University trauma surgery and orthopedics: where is the journey going to?].

In the field of tension between generalists and specialists, in modern university trauma and orthopedic surgery the question arises as to which expertise has the greatest importance for the future of clinical care. University medicine consists of three large pillars: Research, teaching and treatment of patients. Each of these pillars is faced with the challenge of increasing specialization; however, generalists are extremely important for the future of university trauma surgery and orthopedics.

[Peripheral nerve grafting].

Objective: Peripheral nerve lesions often lead to significant and permanent loss of motor and sensory function. The aim of peripheral nerve grafting is to bridge nerve defects.

Indications: When tension-free nerve repair is not possible, peripheral nerve grafting is indicated.

[Treatment concepts for the medial clavicle and the sternoclavicular joint].

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.

[Scientific methods for in-vitro investigations in the field of joint kinematics : Cluster experimental joint kinematics].

In vitro studies are an established method to determine joint kinematics for answering preclinical questions regarding the effects of new treatment options, surgical techniques or implant designs. The lack of standardized, interdisciplinary representation in the determination of joint kinematics poses a problem. In addition to representation forms such as the "neutral-zero method" or the description of movements within the three basic planes, there are other mathematical joint-specific representations of individual working groups.

[Implant anchorage: In vivo and in vitro analyses : Clusters for implant anchorage and safety].

Aseptic implant loosening is the primary cause of revisions in arthroplasty. Various in vitro and in vivo methods are available for assessing implant fixation and stability. The aim of the Musculoskeletal Biomechanics Research Network (MSB-NET) is to continuously improve or develop these methods.

Hydrogel-based and spheroid-based autologous chondrocyte implantation of the knee show similar 2-year functional outcomes: An analysis based on the German Cartilage Registry (KnorpelRegister DGOU).

Purpose: To compare short-term patient-reported outcomes (PRO) of two contemporary matrix-associated autologous chondrocyte implantation (M-ACI) products for the treatment of large articular cartilage defects of the knee.

Methods: A retrospective, registry-based, matched-pair analysis was performed, comparing PRO of patients undergoing isolated M-ACI with either Spherox™, a spheroid-based ACI (Sb-ACI), or NOVOCART™ Inject, a hydrogel-based ACI product (Hb-ACI), for a focal full-thickness cartilage defect of the knee ≥4 cm. Matching parameters included age, sex, body mass index, defect size, defect localization, symptom duration and previous surgeries.

[Controversies in promoting young talent in orthopedics and trauma surgery].

Background: The field of orthopedics and trauma surgery is facing a serious shortage of new talent due to the increasing average age of active surgeons and a growing need for staff. The appeal of these specialties is declining among medical students.

Solutions: This trend could be reversed by introducing practice-oriented curricula, mentoring programs, and early integration into professional societies.

Operative management of osteochondral lesions of the talus: 2024 recommendations of the working group 'clinical tissue regeneration' of the German Society of Orthopedics and Traumatology (DGOU).

The working group 'Clinical Tissue Regeneration' of the German Society of Orthopedics and Traumatology (DGOU) issues this paper with updating its guidelines. Literature was analyzed regarding different topics relevant to osteochondral lesions of the talus (OLT) treatment. This process concluded with a statement for each topic reflecting the best scientific evidence available with a grade of recommendation.

Follow-up Treatment after Cartilage Therapy of the Knee Joint - a Recommendation of the DGOU Clinical Tissue Regeneration Working Group.

The first follow-up treatment recommendation from the DGOU's Clinical Tissue Regeneration working group dates back to 2012. New scientific evidence and changed framework conditions made it necessary to update the follow-up treatment recommendations after cartilage therapy.As part of a multi-stage member survey, a consensus was reached which, together with the scientific evidence, provides the basis for the present follow-up treatment recommendation.

[Shoulder-clinical introduction].

Background: Radiological imaging plays a significant role in the diagnostics of shoulder pathologies. Based on a patient's medical history, physical examination and radiological imaging, it is possible to plan the further conservative or surgical treatment.

Objectives: Common pathologies of the shoulder and the correct radiological imaging are presented.

[Trigger finger-pitfalls and differential diagnosis].

The differential diagnosis of a trigger finger presents a clinical challenge. This case depicts a 32-year-old male patient who presented with persistent snapping of the right index finger at the metacarpophalangeal joint without localized tenderness despite previous surgical A1-annular ligament release. CT diagnostics demonstrated a prominent articular tuberosity.

[Fractures of the talar neck and body : An overview].

Fractures to the talar neck and talar body (central talar fractures) are rare injuries but often result in devastating outcomes. It is therefore important to diagnose these injuries early and provide the best possible treatment. The analysis, classification, and surgical planning of central talar fractures should be based on computed tomography (CT) imaging.
