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. In particular, those aspects that are important from a medical point of view for a patient-specific adjustment of outpatient surgery (e. g. old age, frailty, comorbidities) as well as the important structural requirements for outpatient postoperative care were included in the new AOP contract at best in a rudimentary manner. For this reason, the German Society for Hand Surgery felt compelled to give its members a recommendation as to which medical aspects must be taken into account, especially when performing hand surgery operations, in order to ensure the highest level of safety for the patients entrusted to us while performing outpatient surgery. An expert group of experienced hand surgeons and hand therapists who work in hospitals of all levels of care as well as resident surgeons was formed in order to formulate mutually agreed recommendations for action., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Management of scapholunate dissociations remains a significant challenge. Open approaches suffer from a disadvantageous further impairment of the stabilizing local structures. The minimally invasive arthroscopic technique described provides reliable stability of the scapholunate interosseous ligament complex in dynamic lesions. The anatomic key structure is the dorsal capsuloligamentous scapholunate septum, which provides a mechanical connection between the scaphoid, lunate, and dorsal capsule of the wrist. Arthroscopic capsuloplasty aims to tighten and stabilize this complex structure in long term. This approach preserves the adjacent structures, namely the secondary wrist stabilizers and their neuromuscular feedback loops. With a certain degree of experience in wrist arthroscopy, the technique is reliably adaptable and reproducible., Competing Interests: Conflicts of Interest and Source of Funding: The authors report no conflicts of interest and no source of funding., (Copyright © 2022 Wolters Kluwer Health, Inc.

Ulnocarpal impaction syndrome is a common cause for ulnarsided wrist pain caused by an abutment between the ulnar head and the lunotriquetral complex. This pain is typically triggered by load bearing and rotation of the forearm. Radiographic examination is often associated with positive ulnar variance and cysts in the lunate, edema of the ulnoproximal lunate is shown in MRI. Operative treatment aims to reduce load on the lunate, either by open ulnar shortening osteotomy or arthroscopic wafer procedure., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Objective: Arthroscopic decompression (wafer procedure) of the ulnocarpal compartment in patients with ulnar impaction syndrome., Indications: The arthroscopic wafer procedure is recommended in ulnar-plus situations with up to 3 mm length-excess. To perform this procedure the ulnar head needs to be accessible for the burr through a pre-existing, impaction-related, centroradial lesion of the triangular fibrocartilage complex (TFCC). The additional presence of a distal radioulnar joint (DRUJ) type C confirms the indication., Contraindications: The wafer procedure is contraindicated if there is no consistent TFCC injury ensuring access to the ulnar head and furthermore in ulna-plus situations of more than 3 mm. Relative contraindications: in young patients due to lack of evidence-based studies., Surgical Technique: Arthroscopic, semicircular, partial resection of the ulnar head in terms of oblique-helicoidal osteotomy using a 4.2 mm burr, while sparing the DRUJ and the dorsal and the palmar radioulnar ligaments., Postoperative Management: Immobilization for 1 week in a palmar splint with immediate intensive exercising of pro- and supination under physiotherapeutic instruction., Results: Between 2008 and 2010, an arthroscopic wafer procedure was performed in 24 patients. The resection of the ulnar head was 2.5 mm on average. After a mean follow-up time of 13.25 months, very good results were archived in 23 of 24 patients; the ulnar impingement test was negative. On a visual analog scale (0-10) average postoperative pain was 1.16 at rest and 4.5 under stress. The mean postoperative DASH score was 13.4.
