The use of uncemented stems in femoral neck fractures in elderly patients: A comparative study of 671 cases.

Introduction: The use of cemented stems in elderly patients is associated with the risk of intraoperative embolic complications. Uncemented stems eliminate this risk, but their use is controversial because of the risk of mechanical complications, with estimated subsidence between 3.6 and 30% and periprosthetic fractures between 2.

Induced-membrane treatment of refractory humeral non-union with or without bone defect.

Introduction: Treatment of humeral non-union with or without bone defect is complex, with non-negligible rates of complication and failure. Few reports focused on management of treatment failure.

Objective: The study hypothesis was that the induced-membrane technique associated in a 2-stage strategy to internal fixation provides systematic bone healing in refractory humeral non-union.

[The wrapping induced membrane technique for treating recalcitrant non unions].

The induced membrane technique is now well accepted for reconstruction of segmental bone defect. On the other hand, some cases of aseptic non-union are unsuccessfully treated by several surgical attempts for obtaining bone healing. The two stages wrapping induced membrane technique was developed initially for treating atrophic and recalcitrant aseptic non union without bone loss.

Is the position of dual-mobility cup in THA for femoral neck fractures optimal? A retrospective study.

Introduction: Few studies have examined the relationship between the indication of total hip arthroplasty (THA) and the quality of its technical achievement. Implants mispositioning could happen more frequently while THA is performed on acute proximal femur fracture cases. The purpose of this study was to compare the frontal inclination (FTA) of double-mobility cups (DMC) in patients undergoing THA for hip osteoarthritis or fracture.

Comparison of dual mobility total hip arthroplasty and bipolar arthroplasty for femoral neck fractures: A retrospective case-control study of 199 hips.

Background: The choice between performing total hip arthroplasty (THA) or hemiarthroplasty (HA) is not straightforward in older patients with femoral neck fracture, particularly when co-morbidities are factored in. This led us to carry out a case-control study to determine (1) the rate of mechanical complications for these two types of implants, and (2) the rate of medical complications and mortality.

Hypothesis: THA with dual mobility cup (DM) will result in fewer mechanical complications than HA.
