Titanium alloy femoral neck fracture—clinical and metallurgical analysis in 6 cases
Samo K Fokter, Rebeka Rudolf & Andrej MoličnikHip
We present a case series of 6 hips in 6 male patients (average age 50 (37–56) years) who underwent revision of total hip arthroplasty (THA) as a result of a modular femoral neck fracture of an otherwise stable THA (Table 1). All 6 patients presented with acute-onset pain at a mean of 5.6 (2.3–12) years after the index procedure, following an uneventful and asymptomatic initial recovery period. The pain was located in the groin, the patients were unable to tolerate weight bearing, the involved leg was shortened, the hip was in external rotation, and emergency room radiographs revealed a fractured modular femoral neck slightly inside the female taper of the stem (Figure 1).
