Background and Clinical Significance: Since their first introduction in the early 1950s, hip prostheses implants are becoming increasingly reliable; nevertheless, failures can still happen. The focus of this paper is to present a case study on a catastrophic fractured hip prosthesis liner that consequently led to revision surgery and the replacement of the destroyed implant. Case Presentation: The patient was diagnosed with Hodgkin’s lymphoma and had Total Hip Arthroplasty on both legs, but only the right side needed revision due to a fracture in the liner. The patient’s symptoms were a squeaking sound, functional impairment, and pain, and an X-ray showed the extent of the damage. We also present a short review on the mechanisms of liner fracture, focusing strictly on the mechanical aspects of failure. Conclusions: Hip prosthesis implants are not immune to failure. This case highlights the importance of an interdisciplinary approach and emphasizes the need for vigilant postoperative monitoring and the development of predictive tools. Full article

This study aims to evaluate the preliminary effects of a hybrid tele-supervised airway clearance protocol on secretion clearance, health-related quality of life, and patient satisfaction in bronchiectasis patients. A single-arm experimental pilot case series with three participants was conducted, involving six ACT sessions over three days, including one onsite supervised session and five tele-supervised sessions. Assessment measures comprised sputum expectoration, COPD assessment test (CAT), and participant satisfaction ratings. The results showed increased sputum expectoration rates during each ACT session, alongside notable improvements in CAT scores (reductions of 16, 8, and 8 points for each participant). Participants expressed high satisfaction with tele-supervised sessions and reported increased confidence in independent ACT performance post-program. The findings suggest that the hybrid ACT program may be a promising avenue for enhancing bronchiectasis management. However, further research with larger sample sizes and rigorous control groups is necessary to validate its efficacy and broader applicability. Full article
