Rim Fracture of a Tibial Base-Plate Due to Retained Cement as a Cause of Catastrophic Failure of Unicompartmental Knee Arthroplasty: A Case Report.

Case: We report a case of catastrophic implant failure due to fatigue fracture of a well-functioning unicompartmental knee arthroplasty at 7 years in an active 55-year-old man, who presented with sudden onset of atraumatic knee pain and effusion. The patient underwent revision to total knee arthroplasty. Intraoperative findings included a metallic fragment fractured off the rim of the tibial base-plate and cement retained in the tibial tray.

Is Scheduled Intravenous Acetaminophen Effective in the Pain Management Protocol of Geriatric Hip Fractures?

Background: Hip fractures have significant effects on the geriatric population and the health care system. Prior studies have demonstrated both the safety of intravenous (IV) acetaminophen and its efficacy in decreasing perioperative narcotic consumption. The purpose of this study is to evaluate the effect of scheduled IV acetaminophen for perioperative pain control on length of hospital stay, pain level, narcotic use, rate of missed physical therapy (PT) sessions, adverse effects, and discharge disposition in geriatric patients with hip fractures.

Factors used by program directors to select hand surgery fellows.

Purpose: To identify factors and attributes hand surgery fellowship program directors consider important in selecting applicants for interview and ranking.

Methods: A web-based questionnaire was sent to all hand fellowship program directors in the United States. The questionnaire was designed to identify the most important criteria in granting an interview, sources of letters of recommendation, the interview process, and factors used to rank a candidate.

Short, locked humeral nailing via Neviaser portal: an anatomic study.

Objective: Supraspinatus tendon trauma may contribute to residual shoulder pain after nail fixation for proximal humeral fractures. Some have proposed a more medial starting point for humeral nail insertion to avoid cuff tendon footprint damage. We hypothesized that percutaneous nail insertion via Neviaser portal would not only be possible, but would avoid tendon trauma, while sacrificing articular cartilage.

Osteolytic lesion of the tibial diaphysis after cementless TKA.

Biomaterial wear debris is a known contributing factor in aseptic loosening of total joint prostheses, particularly when cementless tibial trays are used in total knee arthroplasty (TKA). Local inflammatory response can lead to osteolysis and aseptic loosening of implants. The resulting lesions require careful clinical evaluation.
