Acetabular peri-prosthetic fractures are rare but their incidence is rising due to the increased prevalence of total hip arthroplasty, the increasing life expectancy and the growing functional demand of an ageing population, the incidence of primary total hip arthroplasty is increasing. They are either intra-operative or post-operative and have various aetiologies. Several factors such as implant stability, bone loss, remaining bone stock, fracture pattern, timing, age and co-morbidities of the patients must be considered for adequate treatment. To date, the literature on this subject has been sparse and no universally recognized treatment algorithm exists. Their rarity makes them a little-known entity and their surgical management represents a challenge for most orthopaedic surgeons. This review aims to present an update on epidemiology, the diagnostic work up, existing classification systems, surgical approaches and therapeutic options for acetabular peri-prosthetic fractures.

This study reports the minimum 10 year results of total hip arthroplasty (THA) performed using a monoblock acetabular component with a large-diameter head (LDH) ceramic-on-ceramic (CoC) bearing. Of the 276 THAs included in this study, 237 (85%) were available for review at a mean of 10.5 years (range, 10 to 12) postoperatively. There were eleven deaths that occurred during the follow-up. Reoperations, implant revisions, adverse events, clinical outcomes, radiographic evaluation, and whole blood metal ion levels were assessed at the last follow-up. After a minimum of 10 years, implant survivorship was 98.7%. There were three revisions (1.3%): one for insufficient acetabular cup primary fixation, one traumatic periprosthetic acetabular fracture, and one probable deep chronic infection. No dislocation or ceramic implant fracture was observed. The mean University of California at Los Angeles (UCLA) activity score, Western Ontario and McMaster Universities Osteoarthritis Index score, and Forgotten Joint Score were 5.6 (2 to 10), 90.1 (9 to 100), and 79.2 (4 to 100), respectively. In the 10 years following implantation, at least 43% of patients reported hearing a squeaking noise from the prosthesis. All patients who had squeaking hips were satisfied with the surgery. The mean titanium level was 2.2 μg/L (1.1 to 5.6). No progressive radiolucent lines, osteolysis, or implant loosening signs were observed at the last radiographic evaluation. A LDH CoC THA provides outstanding long-term (minimum 10 year) implant survivorship with unrestricted activity while avoiding implant impingement, liner fracture, and hip instability. Functional outcomes, satisfaction, and joint perception were excellent. Although the incidence of squeaking was high, it did not affect patient satisfaction or function. The systemic titanium levels were low, related to unavoidable passive corrosion of implant surfaces, and did not reveal any indirect signs of trunnionosis.

Background: Hepatic abscess is a rare condition but comes with heavy consequences if not diagnosed and managed properly. Early detection of this pathology is challenging because of the variety and lack of specificity of symptoms but is necessary for accurate management. Case report: We report a case of pyogenic liver abscess secondary to the migration of an ingested fish bone in a 74-year-old female. We used laparoscopic surgery to drain the abscess, remove the foreign body responsible and look for the perforation site. Parenteral antibiotherapy was added to the surgical treatment. Conclusion: Early diagnosis of hepatic abscess caused by the migration of a foreign body remains a challenge. In our opinion, laparoscopic surgery associated with antibiotics is the safest and most effective therapeutic option.
