Minimally invasive hollow trephine technique is recommended for revision of broken uncemented and extensively porous-coated monolithic femoral stems: a review of three cases

Abstract: Total hip arthroplasty has been used for almost over five decades as a well-established procedure. Increasing number of revision total hip replacements (THR) due to aseptic and septic complications. [1,2] lead to the design of improved revision prostheses. Distally fixed, cementless, cylindrical femoral stems with an extensive porous coating are one of principal revision options in case of failed THR on the femoral side. These stems have been used in absence of adequate proximal femoral bone stock for over 30 … Show more

“…Although some studies have linked excessive body weight of patients to stem fractures,[ 2 3 ] in our study, the body weight of the two patients was only 35.0 kg and 66.8 kg, with BMI of 16.2 and 24.8, respectively. They could not be classified as overweight but fractures still happened, which implies that proximal bone loss and stem sizes are more important risk factors than body weight.…”

“…However, complications of these stems are not uncommon. Fracture of these stems, although rarely reported in literature,[ 1 2 3 ] is challenging for orthopedic surgeons. Extraction of the broken components is difficult, and special instruments or techniques are usually required.…”

“…When the diagnosis was confirmed, several methods were considered for management such as the femoral cortical window approach and the extended trochanteric osteotomy. Nevertheless, these methods are either extreme, offer restricted visibility of the distant fragment, or result in the absence of distal intra-medullary support [ 10 ]. Wroblewski developed an innovative method using specialized tools.…”

“…Revision surgery for stand modular prosthesis due to mechanical failure is not uncommon in orthopaedic oncology, and several studies have documented such revisions. 9 , 10 , 11 , 12 Feasible revision methods for corresponding broken sites, such as corticotomy 9 the hollow trephine technique 11 , 12 for extracting the broken stem, and use of a retrograde inserted instrument for punching the modular prosthetic component, 10 are well documented. However, the literature on revision for 3D‐printed implant is scarce, and clinical experience is limited.…”
