[The complexity of hand-surgical procedures in the context of cross-sector care concepts: a consensus recommendation of the German Society of Hand Surgery].

Overboarding politcal influence in Germany concerning medical issues has come to a new peak. The report by the IGES Institute published in 2022 made an important contribution in this regard. Unfortunately, only that part of the recommendations of this report were implemented in a new version of the contract for outpatient surgery according to Section 115b SGB V (AOP contract), that called for an expansion of outpatient surgery.

Interdisciplinary consensus statements on imaging of DRUJ instability and TFCC injuries.

Objectives: The purpose of this agreement was to establish evidence-based consensus statements on imaging of distal radioulnar joint (DRUJ) instability and triangular fibrocartilage complex (TFCC) injuries by an expert group using the Delphi technique.

Methods: Nineteen hand surgeons developed a preliminary list of questions on DRUJ instability and TFCC injuries. Radiologists created statements based on the literature and the authors' clinical experience.

Osteoarthritis of the Wrist: Pathology, Radiology, and Treatment.

Osteoarthritis (OA) is a degenerative disease that can manifest in any synovial joint under certain conditions. It leads to destruction of articular cartilage and adjacent bone, as well as formation of osteophytes at the edges of afflicted joint surfaces. Regarding the wrist, typical degenerative arthritis affects particular joints at a specific patient age, due to asymmetric load distribution and repetitive microtrauma.

Interdisciplinary consensus statements on imaging of scapholunate joint instability.

Objectives: The purpose of this agreement was to establish evidence-based consensus statements on imaging of scapholunate joint (SLJ) instability by an expert group using the Delphi technique.

Methods: Nineteen hand surgeons developed a preliminary list of questions on SLJ instability. Radiologists created statements based on the literature and the authors' clinical experience.

Carpal Instability: I. Pathoanatomy.

The pathoanatomy of carpal instability is multifactorial and usually complex. A thorough medical history and clinical examination are essential, as well as profound knowledge of the specific instability patterns. The stability of the wrist is ensured by the carpal joint surfaces, by intact intra-articular (particularly the scapholunate interosseous ligament) and intracapsular ligaments, and by crossing extensor and flexor tendons, the latter making the proximal carpal row an "intercalated segment.
