Is Femoral Head to Acetabular Cup Ratio Associated With Dislocation After Total Hip Arthroplasty?

Background: Dislocation remains a common complication following total hip arthroplasty (THA). Previous literature has shown that the femoral head-to-neck ratio is essential in hip motion, function, and stability. While large femoral heads and dual mobility bearings have been developed to improve stability, it remains unknown if the ratio between femoral head size to acetabular cup size also plays a role in stability.

Evaluating Harms Associated with Prolonged Antibiotic Duration of Therapy in Community Dwelling Older Adults: A Cohort Study using Instrumental Variable Analysis.

Background: Shorter courses of antibiotic therapy are increasingly recommended to reduce antibiotic exposure. However quantifying the real-world impact of duration of therapy is hindered by bias common in observational studies. We aimed to evaluate the harms and benefits of longer versus shorter duration of therapy in older adults.

Characterization of genetic diversity and identification of genetic loci associated with carbon allocation in N fixing soybean.

Background: Efficient capture and use of resources is critical for optimal plant growth and productivity. Both shoot and root growth are essential for resource acquisition, namely light and CO by the shoot and water and mineral nutrients by roots. Soybean [Glycine max (L.

Surgical Time and Complication Risk in Conversion Total Hip Arthroplasty With Implant Removal: Finding an Optimal Surgical Duration.

Background: Although longer surgical times in primary total hip arthroplasty (THA) are associated with higher complication rates, this has yet to be explored in conversion THA. The purpose of this study is to investigate the relationship between surgical time and complications in the setting of conversion THA with implant removal. We aim to establish a length of surgery after which the risk of complications increases.

Outcomes in Acetabular Revision for Acute Pelvic Discontinuity Utilizing Plating of the Posterior Column.

Background: Acute pelvic discontinuity (PD) is a rare, yet challenging complication following total hip arthroplasty (THA). Although several techniques, such as plating of the posterior column and spanning of the discontinuity with a cup cage, have been described for the management of acute PD, few studies have determined the survivorship of acetabular constructs in this setting. The purpose of this study was to determine the outcomes of acetabular fixation of the posterior column in patients who had acute PD following THA.
