Adverse Local Tissue Reaction and Osteolysis After Ceramic-on-Ceramic Total Hip Arthroplasty.

Adverse local tissue reaction (ALTR) and osteolysis formation are more frequently described complications after total hip arthroplasty (THA) with metal-on-metal bearings. In this report, we present a unique case of ALTR and osteolysis formation with ceramic-on-ceramic bearing THA, which has been less commonly described in the existing literature. This rare case occurred in a 54-year-old patient who had a primary THA done 17 years prior to representing to our institution.

Intestinal schistosomiasis manifesting as colonic intussusception arising from a mucocele of the appendix: report of a case.

We report a case of intestinal schistosomiasis manifesting as colonic intussusception resulting from a mucocele of the appendix, caused by the obstruction of appendiceal outflow by schistosome egg-induced fibrosis. An 81-year-old woman from China presented with a tender right iliac fossa mass and computed tomography (CT) showed intussusception in the ascending colon. Exploratory laparotomy confirmed an appendiceal mass causing intussusception of the cecum into the ascending colon, with the appendix as the lead point, and lymphnode enlargement.

Osteolysis and wear debris after total knee arthroplasty presenting with extra-articular metallosis in the calf.

Component wear after total knee arthroplasty (TKA) with extruded metallosis in the extra-articular tissue of the calf secondary to a periprosthetic fracture is a rare complication. A 77-year-old man with a failed Insall-Burstein II TKA prosthesis presented with calf cellulitis after a fall. Radiologic evaluation revealed severe osteolysis and loosening of prosthetic components and an intramuscular abscess communicating with the medullary canal of the tibia through an undisplaced periprosthetic fracture.
