Modular titanium alloy neck failure in total hip replacement: analysis of a relapse case.
نویسندگان
چکیده
Modular neck hip prosthesis born in the 1990 with the aim of allowing the surgeon to modify CCD angle, offset and femoral anteversion intra-operatively restoring patient's original biomechanics. In order to achieve the best biomechanics of the reconstructed hip, preoperative planning is essential. In the last few years modularity has been questioned and an argument made for the return to mono block stems due to events of breakage or disconnection of modular components. Fretting or crevice corrosion may lead to failure of such modular device due to the contamination inside the modular coupling or to high loads. We present a case of repetitive modular femoral neck prosthesis fracture.

Modular titanium alloy neck adapter failures in hip replacement - failure mode analysis and influence of implant material
BACKGROUND Modular neck adapters for hip arthroplasty stems allow the surgeon to modify CCD angle, offset and femoral anteversion intraoperatively. Fretting or crevice corrosion may lead to failure of such a modular device due to high loads or surface contamination inside the modular coupling. Unfortunately we have experienced such a failure of implants and now report our clinical experience wi...
متن کاملComment on: Modular titanium alloy neck failure in total hip replacement
To the Editor of the SICOT-J Orthopaedic Journal, I am writing to you as I would like to kindly express some considerations on the case-report of Dr. Marco Ceretti on ‘‘Modular titanium alloy neck failure in total hip replacement’’ published in your on-line journal last April (M. Ceretti and F. Falez SICOT J 2016, 2, 20). The Authors report on ‘‘a case of a repetitive modular femoral neck prost...
متن کاملCorrosion and adverse local tissue reaction after total hip arthroplasty with a modular titanium alloy femoral neck
This report describes a case of mechanically assisted crevice corrosion and secondary adverse local tissue reaction in a patient following a total hip arthroplasty, utilizing a modular neck (bi-modular) femoral component. Radiographic evaluation demonstrated a well-positioned, stable, cementless arthroplasty. Upon further evaluation, the patient had elevated serum cobalt and chromium levels, an...
متن کاملNeck fracture of a cementless forged titanium alloy femoral stem following total hip arthroplasty: a case report and review of the literature
INTRODUCTION Fractures of the neck of the femoral component have been reported in uncemented total hip replacements, however, to our knowledge, no fractures of the neck of a cementless forged titanium alloy femoral stem coated in the proximal third with hydroxy-apatite have been reported in the medical literature. CASE PRESENTATION This case report describes a fracture of the neck of a cement...
