Event Description

A journal article was retrieved from arthroplasty (2021) that reported a study from the united kingdom.The aims of this single center study are to review the mid-term outcomes of porous tantalum cups (tm) and evaluate complications.The data were collected from 2006 to 2018.A total of 59 acetabular revisions in 58 patients were performed using an uncemented tm acetabular component (trabecular metal¿ zimmer biomet) by a single surgeon.Additional screws were used as necessary.Augments were used in two revisions.The head and a constrained liner were also placed.Four patients were lost to follow-up and 13 died during the period without having further surgeries attributed to hip arthroplasty.The remaining 41 patients (42 joints) who underwent revision hip arthroplasty had complete data available.Aseptic loosening (60.3%) of the cup was one of the main indications for the revision surgery, followed by femoral aseptic loosening (11.8%), fracture (11.8%), cup-malalignment (8.8%), infection (3.3%) and metal-on-metal related pathology (4%).The study population had a mean age of 70.11 years at time of surgery (range 30 to 87 years); 23 males, 36 females.Follow-up was conducted clinically and radiographically at six weeks, six months, and annually thereafter with a mean length of follow-up for 87 months (range 24-144 months).The study reported one patient was diagnosed with deep vein thrombosis below the knee which was treated as per the local treatment protocol.Attempts have been made and additional information on the reported event is unavailable at this time.

Manufacturer Narrative

This follow-up report is being submitted to relay additional information.It was reported by a clinical study that a patient underwent a hip arthroplasty.Subsequently, was diagnosed and treated for a lower extremity deep vein thrombosis.Procedural related complications are influenced by the type of surgery, patients pre-existing comorbid state, and perioperative management.Deep vein thrombosis, or dvt, occurs when a blood clot forms in one of the deep veins of the body.This can happen if a vein becomes damaged or if the blood flow within a vein slows down or stops.Total joint patients are typically placed on medication post-operative for a period of time to prevent the development of dvt/blood clot.Even with the administration of preventive medication, dvt/blood clots can still develop.As the complaint indicated, a post-operative complication developed, and medical intervention was required to treat the complication.The root cause of the reported event was determined to be unrelated to the implanted zimmer biomet device; therefore, a review of the device history records will not be performed.If any further information is found which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.
