The present study aimed to evaluate periprosthetic bone mineral density (BMD) changes around a cementless short tapered-wedge stem used for total hip arthroplasty (THA) and to determine the correlation between BMD changes and stem alignment after THA. ⋯ We demonstrated that periprosthetic BMD was well maintained in the proximal femur after THA with a short tapered-wedge stem and that stem anteversion affects periprosthetic BMD after THA.

Comparative Study
Risk of stem undersizing with direct anterior approach for total hip arthroplasty.
The direct anterior approach (DAA) for total hip arthroplasty (THA) is claimed to be as effective but less invasive than the conventional posterior approach (PA). However, the higher risk of femoral fracture and soft tissue damage cannot be underestimated. The present authors believe that the difficult femoral exposure and the surgeon's knowledge of possible complications related to femoral preparation may result in a higher rate of undersized stems when compared to PA, even when a short femoral component is employed to minimise these risks. ⋯ The technical difficulty of femoral preparation and the surgeon's knowledge of possible related complications might lead to implant undersized stems more frequently through DAA than through PA, especially if intraoperative imaging controls are not used.

Hip fractures are becoming an increasing public health issue due to an ageing population (1). Total hip replacements (THR) produce better outcomes in certain patients who were functioning independently before the injury (2). We aimed to assess whether the management of intracapsular hip fracture is carried out in accordance with the National Institute for Health and Care Excellence (NICE) hip fracture guidance (1) and the outcomes with regards to performing THRs on those patients who fulfil the described criteria. ⋯ Of those eligible for a THR, the patients who underwent that procedure had a significantly lower mortality rate compared to those who underwent a hemiarthroplasty (0% versus 19.6% at 1 year, p = 0.007). However, those who did not meet the NICE criteria but underwent a THR had the worst mortality rate (50% at 30 days and 1 year). The provision rate of THR in displaced intracapsular hip fracture is low at 41.0% for those who met the NICE criteria. The results suggest that the decision process when determining if a patient should undergo THR for a fractured neck of femur is multifactorial.

Acetabular deficiencies in young patients can be restored in several ways during total hip arthroplasty. Currently, cementless cups are most frequently used. Impaction bone grafting of acetabular defects is a more biological approach, but is it cost-effective in young patients on the long term? ⋯ Based on this model, the first choice of treatment of the acetabular bone deficient osteoarthritic hip in a young patient is reconstruction with impaction bone grafting and a cemented cup.

Randomized Controlled Trial
Combined use of intravenous and topical tranexamic acid following cementless total hip arthroplasty: a randomised clinical trial.
This study was designed to compare the efficacy and safety of the combined use of tranexamic acid (TXA) with the intravenous (IV) or local use alone in total hip arthroplasty (THA). ⋯ Combined use of intravenous TXA and local TXA in primary unilateral THA can effectively decrease total blood loss and increase postoperative haemoglobin levels without influencing complication rates. It is suggested that this combined TXA regimen is more effective in decreasing blood loss in cementeless THA than intravenous or local administration alone.
