A Single Dose Versus Two Doses of Tranexamic Acid for Extracapsular Hip Fractures.

Objective In this study, we aimed to compare the effectiveness of one dose of tranexamic acid (TXA) at the time of hospital admission versus two doses of TXA (one at the time of hospital admission and another dose intraoperatively) in reducing perioperative total blood loss in patients with extracapsular hip fractures. Methods This retrospective cohort study included 80 patients from a single institution who underwent surgical fixation for extracapsular hip fractures. Forty patients received a single dose of 1 gram of TXA at the time of hospital admission (per standardized protocol of an ongoing research study at the time), and 40 patients received the same dose of TXA on hospital admission as well as a second dose of 1 gram of TXA intraoperatively at the time of incision (per standard practice change following the completion of the research study).

Total shoulder arthroplasty for glenohumeral arthritis associated with posterior glenoid bone loss: results of an all-polyethylene, posteriorly augmented glenoid component.

Background: Posterior glenoid bone loss is commonly encountered in total shoulder arthroplasty (TSA). The purpose of our study is to report the clinical and radiographic findings of patients with a minimum of 2 years' follow-up treated with an all-polyethylene, augmented glenoid component.

Methods: Twenty-two shoulders with posterior glenoid bone loss were treated by a single surgeon.

Radiographic evidence of regression of a solitary osteochondroma: a report of 4 cases and a literature review.

Solitary osteochondromas are considered to be the most common benign bone tumor. Slow progressive osteochondroma growth is the rule in skeletally immature patients, at times prompting surgical excision. Significant growth of a lesion beyond skeletal maturity is commonly considered to be a harbinger of malignant transformation.
