Fracture of an Exeter Stem

Prosthetic Fracture of a Cemented Exeter Femoral Stem (Case Report)

“…The finish was ultimately reverted to the polished type in 1986 due to inferior results. The Exeter is a superior prosthesis with a long history and excellent long term results in all major registries [6]. Specifically, the Contemporary/Exeter stem combination has a 10yr revision rate of ranging from 3.2-6.0% depending on acetabular component choice.…”

“…Hamlin et al (2014) reported on a single case of Exeter prosthesis fracture at the trunion-neck junction, in an obese (141kg), elderly male patient who sustained a fall from standing height [11]. He was also noted to have a relatively under-sized stem.…”

Neck fracture of the Exeter stem in 3 patients

“…They did not state the stem specifications. However, 1 recent case report described a patient with a fracture in the neck of the Exeter stem (Hamlin and MacEachern 2014 ). To our knowledge, this is the only neck fracture of the Exeter stem that has been reported to date.…”

“…A recent paper by Hamlin and MacEachern ( 2014 ) described 1 patient with fractured neck, after THR with the Exeter V40 stem. This patient was morbidly obese, weighing 141 kg, and therefore quite different to those described in our report.…”

Fatigue fracture of a cemented Omnifit CoCr femoral stem: implant and failure analysis

“…Since the 1970s, improvements in stem design [1] and metallurgy [3] have markedly reduced the incidence of femoral stem fracture. However, reports of femoral stem fracture have continued to surface in the orthopaedic literature, with causes ranging from corrosion at the head-neck interface [4] , [5] , [6] to defects caused by laser etchings [7] , [8] , [9] . Some investigators [10] , [11] , [12] have reported that insufficient proximal bone support may predispose femoral stems to fracture via fatigue loading, while others [13] have suggested that distal fixation is adequate in this system.…”
