Event Description

"literature article entitled, ¿prosthetic hip infection with edwardsiella tarda in sickle cell beta thalassemia disease: a case report¿ by david b.Frumberg, md, et al, published by journal of clinical orthopaedics and trauma (2016), vol.7s, pp.130-133, was reviewed for mdr reportability.The authors report a previously unrecognized gram-negative bacillus as the infecting agent in a patient with bilateral total hip arthroplasties for stage iv osteonecrosis.A (b)(6)-year-old male with combined sickle cell disease and beta thalassemia with a prior history of unknown hip surgeries and treatment for distal tibial osteomyelitis in africa developed a periprosthetic joint infection; intra-operative cultures confirmed the infecting organism to be edwardsiella tarda which was sensitive to late-generation cephalosporins and vancomycin.He was successfully treated with a staged revision total hip arthroplasty with an antibiotic spacer and has been infection-free since.The patient he underwent a right tha with a cementless modular stem, ceramic-on-ceramic bearing, and cementless cup (s-rom modular implant with a duraloc acetabular cup, depuy).During seating of the metaphyseal sleeve, an incomplete calcar fracture at the level of the lesser trochanter was discovered and fixed with two cerclage cables.Perioperative course was otherwise uneventful.Two months post-operatively, he had a sickle cell crisis which was conservatively managed.At his four-month postoperative clinic visit, a superficial wound dehiscence was observed which was treated aggressively with 1 week of iv vancomycin and oral amoxicillin.His dehiscence closed but an area of subcutaneous abscess emerged, from which purulent material was aspirated.He was indicated for surgical exploration and debridement of the wound.During surgery, purulent drainage was noted from a sinus in the fascia lata, but the short external rotators and hip joint capsule were intact.Intraoperative cultures were negative.Per infectious disease recommendations, he was discharged on a two-week course of oral amoxicillin/clavulanic acid.After 4 weeks, he reported increased pain and wound drainage and was indicated for irrigation and debridement.During surgery, the fascial sinus was observed to communicate with the hip joint.The acetabular component was well fixed, but the femoral component was loose.The stem and sleeve were removed and an antibiotic cement spacer with 6gm of vancomycin and 7.2gm of tobramycin was placed (competitor product).After 3 weeks of aggressive antibiotic treatment, he was then indicated for second-stage reimplantation.He underwent irrigation and debridement, removal of cement spacer, and revision tha with a cementless modular femoral stem, ceramic-on-polyethylene bearing, and a cementless acetabular component (competitor products).The acetabular components and femoral head were explanted due to infection.There was no reported product problem with the components.The authors note that patients who have sickle cell crisis and iron overload are highly susceptible to the infectious organism e.Tarda.They further note that this was the first known, reported case of e.Tarda periprosthetic infection.Captured in this complaint: s-rom stem and sleeve for implant loosening and infection, duraloc cup and locking ring, ceramic head, and ceramic liner for infection.The femoral head and acetabular components had no reported product deficiencies.During the index tha, the patient had no discernable femoral canal and the surgeons had to perform extensive reaming to insert the stem and sleeve causing the intraoperative calcar fracture.".
