The indication for surgical treatment of lateral snapping elbow syndrome is recurrent joint blockage in combination with pain of the affected elbow joint. Different parts of the lateral synovial capsule sleeve complex, including the annular ligament itself, a hypertrophic synovial fold, or meniscus-like soft tissue interposition can lead to painful entrapment. Surgical treatment options can include an arthroscopic or open procedure. The aim of this technical note is to provide a step-by-step illustration of the authors' preferred arthroscopic approach with a comprehensive review of literature on clinical outcome.

Introduction: As a consequence of the Swedish model, endoprosthesis registers have become increasingly important worldwide. Due to the increasing number of joint replacements at the shoulder, these are being increasingly included in the register databases - in addition to interventions at the hip and knee joint. In this study, the value of endoprosthesis registers is investigated, using the example of shoulder endoprosthetics and including a comparison with clinical studies.

Material and methods: The annual reports of 32 different endoprosthesis registers with data on hip, knee and/or shoulder arthroplasty were analysed. The number of operations and demographic patient data for all areas of endoprosthetics were examined. In addition, a more detailed consideration of variables such as the primary diagnosis, the cause of the revision, the revision rate depending on risk factors and patient-reported outcome measures (PROM scores) was carried out exclusively for the shoulder joint endoprostheses. Using the example of the inverse shoulder prosthesis, clinical studies were compared to registry data with special regard to the revision rate.

Results: A total of 20 endoprosthesis registers could be included, 9 of these collected data on shoulder arthroplasty. The main primary diagnoses were osteoarthritis (40.6%), rotator cuff defect arthropathy (30.2%) and fractures (17.6%). The most commonly used shoulder joint endoprosthesis was the inverse prosthesis (47.3%). The proportion of revision surgeries in total shoulder arthroplasty operations was less than 10% in all registers. In addition to the revision rate, the PROM scores were sometimes used in the registers to evaluate the success of the prosthesis. Compared to registry data, clinical studies showed more heterogeneous data with a significantly higher revision rate of over 10% in long-term follow-up - using the example of the inverse shoulder prosthesis.

Conclusion: Register data are a valuable source of information in shoulder arthroplasty and can make a significant contribution to the quality assurance of endoprosthetic treatments. Compared to clinical studies, they primarily provide data on durability of different endoprosthesis and give lower revision rates. Clinical studies use PROM scores and clinical and radiological examinations to focus only on individual implants and surgical centres on the one hand and much more on the functional results on the other.

Purpose: This study was designed to observe the medium-term efficacy of an induced membrane technique combined with a locking compression plate as an external fixator for the treatment of tibia infected bone defects.

Methods: Patients with a tibial infection were admitted to our department between January 2013 and November 2014. All patients were treated with the induced membrane technique. In the first stage, polymethyl methacrylate (PMMA) cement was implanted in the defects after debridement and then fixed with a locking compression plate (LCP) as an external fixator. In the second stage, bone grafts were implanted to rebuild the defects. The external plates were replaced with nails in 57 patients (internal group), and the remaining 30 patients were not exchanged with fixation (external group). The infection control rate, bone union rate, and complications of the two groups were compared.

Results: Eighty-seven patients were enrolled in this study, and all patients had a minimum follow-up of 5 years (average 62.8 months) after grafting. Eighty-three patients (95.4%) achieved bone union, and the average union time was 6.77 months. Five patients (5.7%) experienced recurrence of infection. Complications included pin tract infection, fixation loosening, deformity connection, and limitation of joint range of motion (ROM). No significant differences in the infection control rate or bone defect union rate were noted between the two groups. The overall rate of complications in the external group was 50%, which was greater than that noted in the internal group (21.1%).

Conclusions: Locking compression plates are external fixators with smaller sizes that are easier to operate than conventional annular fixators or assembled external fixators. The use of locking compression plates in combination with the induced membrane technique in the treatment of tibia infected bone defects can achieve good clinical efficacy after medium-term follow-up.

The complex regional pain syndrome (CRPS) usually occurs within a few weeks in 2-5% of all patients after trauma or surgery or subsequent measures of the distal extremities. There are certain risk factors for its occurrence but no "CRPS personality", instead there are factors that negatively influence the course. The prognosis is generally good ("rule of thirds"), but remaining limitations are common. The diagnosis is clinically possible according to the "Budapest criteria". Additional examinations are possible in case of doubt but are neither conclusive nor exclusive. Corticoids and bisphosphonates are used alongside drugs that have an effect on neuropathic pain. Invasive therapies do not have good evidence and have therefore lost their importance. The rehabilitative therapy is carried out actively and with a lot of self-exercises at an early stage. Invasive anesthetic, passive therapies are obsolete. Special forms of treatment are "graded exposure" (GEXP) in the case of dominant anxiety and, e.g., "graded motor imagery" (GMI) in case of neglect-like symptoms. In addition to educational and behavioral therapy elements, psychotherapy for CRPS also includes participation as part of graded exposure.
