Following anterior cruciate ligament (ACL) injury of the knee, the functional hop test (an averaging of 4 component hop tests including single-hop, triple-hop, cross-over-hop, and 6-meter-hop) is commonly used by sports medicine physicians, doctors of physical therapy, and athletic trainers in return-to-practice and return-to-play decision making. In this case report, the functional hop test was applied to a 31-year-old recreational basketball player status-post full-tear of the anterior talofibular ligament (ATFL) to examine the applicability of a standardized, efficient, and easy-to-administer functional test in making return-to-play decisions following an ankle injury. The functional hop test was administered 5 times across a treatment course of 11 physical therapy sessions emphasizing pain-free range of motion, baseline strength, weight-bearing loading, and sport-specific training. The functional hop test was found to be a helpful (albeit imperfect) tool for clinical decision-making following an ankle injury. Specifically, improvements in landing skill/confidence of single hop accounted for the greatest gains in total score in the early phase of rehabilitation, while momentum and plyometric skill/control of triple hop accounted for the greatest gains in total score in the later phase of rehabilitation. Modification of the functional hop test to include sub-component tests of strength, endurance, and/or lateral hops are discussed.

Recent developments in digital health technologies are overwhelming, and their use in routine work is still difficult to anticipate. This narrative review summarizes the concept of consecutive cohorts in the literature, together with local research experiences in consecutive rheumatic outpatients. Digital health techniques have to reflect the clinicians’ needs, support real-life care of patients, and allow for the specific assessment of quality parameters fulfilling the Donabedian aspect of qualified health care, using quality indicators to improve health care and research. Rapidly growing observational cohorts will perform best to provide follow-up data as the basis for further development of healthcare approaches for rheumatic patients. The challenges of a selection bias, patients with limited disease expression, and chances of early detection of patients with rare diseases are addressed. For research purposes, sequential analyses with growing cohort size, comparative cross-sectional studies with sequential hypothesis testing and other prognostic, diagnostic, and therapeutic aspects of patient management can be performed. With the support of new technologies, young clinicians can easily approach such clinical topics, and learn about clinical data analyses. The use of quality standards as proposed in international recommendations for diagnostic issues and classification criteria, management recommendations, monitoring, and training issues can be supported by digital technologies. In conclusion, collaborative projects allow detailed clinical analyses of large cohorts, but local initiatives can prepare these co-operations, provide first local logistics and research experiences, and teach clinicians how to perform clinical research. Digital health technologies will strongly support these local initiatives.

Rheumatology, the medical specialty dealing with the diagnosis and treatment of rheumatic and musculoskeletal diseases (RMDs), is evolving with the emergence of digital health technologies, such as electronic health records (EHRs), virtual visits, mobile health (mHealth), wearable medical devices, social media, websites, digital therapeutics, artificial intelligence (AI) and machine learning. These technologies offer new opportunities to improve essential aspects of care, such as care access or disease management. They can significantly reduce the risk of errors and the workload of rheumatologists, while enhancing communication between physicians and patients, resulting in better quality of care. Moreover, digital health technologies can significantly improve research outcomes. However, digital health technologies in rheumatology also face specific barriers such as privacy, security concerns, incremental costs as well as limited digital health literacy and access. Therefore, further analysis, actions and strategies are needed to overcome these barriers. This article explores the impact of digital health technologies on rheumatology practice and highlights their contributions and challenges. By understanding the immense potential and overcoming the obstacles, the way for a future where digital health technologies are integrated into daily rheumatology care may be envisioned, in order to empower patients and healthcare providers.

This paper provides a review of the years of experience of hip sonography since the first ultrasound (US) course in Italy in 1987. Clinical and US findings were correlated in 1,000 newborns examined consecutively in a study in 1991. Developmental dysplasia of the hip (DDH) was present even in the absence of clinical signs, including the Ortolani sign. The percentage of US diagnosis of DDH in newborns was 2.8%, while instability according to the Ortolani test was present in 0.75%. After recommendations from the American Academy of Pediatrics against universal US screening, early diagnosis decreased from 74.4% in the period 1992–2002 (43,418 hips examined) to 52.7% in 2013–2014 (5,598 hips examined). In order to answer the question of whether early treatment of DDH has better outcomes, the acetabulum maturation was studied in 93 type III hips. The statistical analysis showed a strong dependency (P < 0.001) between the alpha-angle gain and the age at which treatment was started. The first 2 weeks of life is the optimum time for early diagnosis and treatment; after 6 weeks of life, treatment is less effective and the results are less predictable. Furthermore, the role of the labrum and its morphological changes was analyzed in 86 unstable dysplastic hips (13 type D, 49 type III and 24 type IV) in patients with an average age of 53 days (range 1–134 days) at DDH diagnosis and the beginning of treatment. The labrum was never inverted and underwent a statistically significant increase in echogenicity and dimensions with a frequency of 97% and 96% respectively, suggesting the labrum’s stabilizing role. Abnormal findings such as in achondroplasia, cleidocranial dysplasia, other rare osteochondrodysplasias and in coxa vara are underlined. Uncommon findings such as incomplete acetabular bony rim and eccentric position of the femoral head nucleus are also described.

The diagnosis of hip dysplasia has developed very differently in different countries over the last few decades. The development and current situation in Hungary is described in this paper. The Ortolani test is still the gold standard for clinical examination in most regions. Hip sonography is not officially established and is only used occasionally. However, thanks to private initiatives, more and more orthopaedic surgeons are now familiarising themselves with this method and the first courses are being held in accordance with International Interdisciplinary Consensus Committee on DDH Evaluation (ICODE) guidelines. A regional screening with Graf hip sonography was carried out in Szeged. The results of the evaluation impressively demonstrate the efficiency of this method.
