Thompson Hemiarthroplasty: Asymptomatic after 40 Years - a Case Report

Thompson hip hemiarthroplasty: Asymptomatic after 44 years a case report

“…Restoring hip anatomy with good abductor lever arm and appropriately sized femoral head 8 must be a priority to achieve optimum results. 5,8 Marchetti et al noted the fact that Moore prosthesis does not have a polyethylene element prevented the development of osteolysis. 8 Our patient had bilateral Thompson hemiprostheses with the right side converted to a total hip arthroplasty 25 years after the original surgery.…”

“…6,7 There are few case reports of long-term follow-up of the hemiarthroplasty in the literature. 5,8,12 Wolfson and Waddell reported a female patient who received a Moore hemiarthroplasty after failed pin fixation following traumatic femoral neck fracture. 12 She enjoyed 32 years of unrestricted lifestyle after which the hip became progressively symptomatic and she underwent a conversion to total hip arthroplasty after 32 years.…”

“…12 Recently, Kelley et al reported on a young, fit postman with an asymptomatic Thompson hemiarthroplasty after 40 years of heavy normal use. 5 Marchetti et al reported a patient who received bilateral Moore prostheses for bilateral avascular necrosis of the femoral head and both hemiarthroplasties were intact after 35 years. 8 The patient sustained a periprosthetic fracture (Vancouver B1) on the left side 35 years after the index surgery which was treated with plate and wire fixation because the prosthesis exhibited excellent acetabular cartilage tolerance and clinical condition, and showed no signs of loosening or osteolysis.…”
