Numerous studies have shown that geriatric cooperation models in traumatology lead to significantly reduced morbidity and mortality rates. Even though national and international orthopedic and trauma societies recommend expanding these concepts to include nontrauma-related musculoskeletal diseases, unfortunately, to date only a few of these projects have been implemented. The present article deals with the necessary personnel and infrastructural implementation of aso-called orthogeriatric concept and puts the special features of this new type of treatment in direct comparison with known traumatological cotreatment concepts.

Radiosynoviorthesis (RSO) is an established therapeutic method for the local treatment of pain in aseptic joint inflammation (e.g. arthritis, activated osteoarthritis, synovitis). RSO can be used for the treatment of synovial membrane inflammation of the finger joints such as the thumb's carpometacarpal joint. The beta emitter Erbium-169 (Er-169) is injected into the joint space, which irradiates the inflamed synovialis, thereby leading to fibrosis and obliteration of the pain receptors of the synovial membrane. The chances of success in the treatment of the thumb's carpometacarpal joint by RSO are estimated to be 54-100% within 2-6weeks after therapy.

The complex kinematics of the saddle joint has been achallenge in the development of trapeziometacarpal prostheses. The introduction of the dual-mobility design increases the range of motion and limits strains on the cup fixation. Therefore, rates of loosening and dislocation have been markedly reduced. Furthermore, several studies showed asimilar relief of pain, range of movement and grip strength compared to the results of resection arthroplasty. The preservation of the length of the first ray as well as the more stable and functional joint can be favourable in younger and active patients. Further investigation is needed to determine whether or not those higher demands affect long-term survivorship. The high grade of patient satisfaction, the shorter recovery time and the safe surgical technique motivates considering the implantation of atotal endoprosthesis with adual-mobility cup as an attractive alternative to resection arthroplasty in the operative treatment for trapeziometacarpal osteoarthritis.

Children and adolescents with neuromuscular scoliosis usually undergo severe challenges with their respiratory and locomotor systems during growth. Early onset scoliotic deformities take awhole team of specialists to ease the problematic side effects associated with poor posture and seating abilities. Wheelchairs and seating shells need to be adjusted as does suitable bracing for the collapsing spine. Key issues are the maintenance of proper lung function and upright sitting in the wheelchair or seating shell. Although spine bracing can be helpful and has its place in seating, the natural history of progression in neuromuscular curvatures is rarely sustainably stopped. While bracing is sometimes not tolerated by patients with severe hypotonic thoracic collapse and breathing issues, it can otherwise buy time for some patients to gain height and weight before surgical intervention inevitably takes place.

As part of the underlying condition, neuromuscular scoliosis occurs in early childhood. Compared to idiopathic scoliosis, neuromuscular scoliosis shows amore rapid progress of deformity, which continues even after the end of growth. This progress and the associated complications can only be prevented by surgical treatment. Depending on the patient's age and the extent of the deformity, different strategies have been established: in early childhood, so-called "growing implants" are used, while between the ages of 10 to 12, definitive treatment by reposition and fusion of the deformity is the treatment of choice. In this review, we present different surgical strategies as well as indications for surgery and discuss challenges in the treatment of these complex deformities.

Wide awake local anesthesia no tourniquet (WALANT) refers to an anesthesia technique with low bleeding and complication rates, which enables interventions on the hand in an awake patient without the use of a tourniquet. Bleeding control is achieved through addition of vasoconstrictors to the infiltration solution. Since the motor function of the extremity is not affected, it offers the additional possibility of intraoperative active function testing. The WALANT procedure constitutes an established, effective, easily learnt and resource-sparing technique. The spectrum of surgical possibilities with WALANT is wide and covers nearly all elective and many emergency procedures. Due to multiple advantages in contrast to other regional and general anesthesia procedures, WALANT features an increasing spectrum of surgical applications and practitioners. It is therefore of interest for hand surgeons working both in hospitals and private practices.

Unicompartmental knee arthroplasty, especially for both femorotibial compartments of the knee, is an established partly joint-saving treatment option for osteoarthritis of the knee if the disease is limited to one compartment. Even smaller implants or resurfacing of the patellofemoral joint have been shown-in smaller patient collectives-to have the potential to yield good clinical results.

Regarding the importance of ligament replacement in existing osteoarthritis three topics are highlighted: the development of osteoarthritis after ACL-tear or -replacement, ACL-replacement in existing osteoarthritis and ACL-replacement together with medial unicompartmental knee replacement. Concomitant lesions at the meniscus and cartilage, especially the patella-femoral cartilage are risk factors for the development and progression of osteoarthritis in ACL insufficiency. The treatment of asymptomatic ACL-insufficiency in existing osteoarthritis in the elderly patient is directly dependent on pre-existing degenerative changes. Medial unicompartmental knee replacement and ACL-replacement can, however, be well combined and lead to very good long-term results even in the young patient.

The decision for total hip arthroplasty (THA) is based on pain, loss of function, radiological changes and failed conservative therapy. These criteria are rarely based on systematic research and have not been integrated in generally accepted treatment guidelines. Aim of our study was, therefore, to analyse which decision criteria German orthopaedic and trauma surgeons use in order to recommend THA for patients with hip osteoarthritis. From 10/2019 to 07/2020 we conducted anation-wide survey among 218 orthopaedic and trauma surgeons about their criteria for and against THA surgery, as well as their treatment objectives. 147 fully completed questionnaires were analysed. Pain (99%), limitation of movement (99%), as well as impairment of walking distance (97%), and the subjective burden (97%) were the most frequent criteria. 97% and 96% of surgeons consider prescription of analgesics and physical therapy, as well as alack of their effectiveness, as criteria for THA. 87% see radiological changes grade Kellgren & LawrenceIII as threshold. Arecommendation against surgery is triggered by obesity (BMI ≥ 40 kg/m2) in 48% and by the presence of an active infection in 96%. Current surgeons' practice criteria of recommendations for THA in Germany seem to reflect widely nationally and internationally discussed recommendations. Particular attention is given to patient factors like pain, loss of function and subjective burden, as well as previous conservative treatment and contraindications, like poorly controlled diabetes or an active infection, whereas morbid obesity is not seen as contraindication by all surgeons.

Fast-track treatment concepts were developed decades ago in general and abdominal surgery and have been adapted in recent years for the special requirements of hip and knee arthroplasty. In this field, Hendrik Husted in particular was able to demonstrate scientific evidence for the components of fast-track concepts. The primary aim is not so much to shorten the patient's hospital length of stay (LOS) but rather to effectively increase the quality of medical treatment for the patient and to reduce complications. The optimization of organizational processes as well as intraoperative and perioperative surgical approaches are essential components regarding the introduction of fast track into the clinical routine. This article gives acomprehensive overview of fast-track treatment concepts and explains the scientific principles for the approach.
