The Longest Known Follow‐Up of Vitallium Mold Arthroplasty in China: A Case Report and Literature Review

Abstract

Background: Before the advent of total hip arthroplasty, Vitallium mold arthroplasty had been widely performed. We present a case with a 42-year follow-up after Vitallium mold arthroplasty. To our knowledge, this case represents the longest known follow-up of Vitallium mold arthroplasty in China.Case presentation: This was a 59-year-old male. He underwent Vitallium mold arthroplasty of the left hip 42 years ago because of osteonecrosis of the femoral head. He developed left hip pain 3 months ago and underwent total hip revision surgery. There was some clear synovial fluid in the hip joint. The mold was loosened entirely and taken out effortlessly. Gram-positive cocci could be observed occasionally in the synovial fluid smear, while the synovial fluid culture was negative. The inflammatory markers elevated perioperatively, and prophylactic cefuroxime and vancomycin were utilized successively. All elevated inflammatory markers fell since postoperative day 5, and there was no other sign of infection. The pain and function of the hip joint improved significantly after surgery.Conclusions: Although Vitallium mold arthroplasty was inferior to total hip arthroplasty in survival rate and functional outcome, it did provide an excellent long-term function of the hip joint.

Towards the First Generation of Biomimetic Fixation for Resurfacing Arthroplasty Endoprostheses

“…This allowed movement between the cup and the bone surfaces of the acetabulum and the femoral head and neck and since then Vitallium ® mould arthroplasty has been widely performed. Its survival rate and functional outcome were inferior to total hip arthroplasty, and it was found to provide long-term function of the hip joint [15,18,20], but the general material performance and implant survival turned out to be unpredictable and poor [20][21][22][23]. Although Vitallium ® was found to be an inert and durable material for this type of surgery, its surface characteristics were less than adequate [24].…”
