Reverse total shoulder arthroplasty within 6 weeks of proximal humerus fracture is associated with the lowest risk of revision.

Background: Reverse total shoulder arthroplasty (RTSA) has become an increasingly popular treatment strategy in the management of complex proximal humeral fractures (PHFs). However, no definitive consensus has been reached regarding the optimal surgical timing of RTSA following PHF, particularly considering nonoperative management is often a viable option. Therefore, the aim of this study was (1) to identify optimal timing intervals that maximize the likelihood of revision following RTSA and (2) to determine differences in revision etiologies using the identified timing intervals.

Pediatric Hip Dysplasia Surgery Outcomes by Pediatric Versus Nonpediatric Orthopedists.

Objectives Developmental dysplasia of the hip (DDH) encompasses a spectrum of abnormalities in the immature hip. Surgical intervention is indicated if conservative management fails. Despite the increased supply of pediatric orthopedic surgeons (POSs) over the last few decades, there continues to be a maldistribution of surgeons.

The Association Between Oral Bone Mineral Density-Reducing Medications and the Risk of 2-Year Implant-Related Complications Following Total Knee Arthroplasty.

Background: Certain medications interfere with the bone remodeling process and may potentially increase the risk of complications after total knee arthroplasty (TKA). As patients undergoing TKA may be taking these bone mineral density (BMD)-reducing medications, it is unclear as to whether and which medications impact TKA outcomes. Therefore, the purpose of this study was to observe the impact of various BMD-reducing medications on 2-year implant-related complications following TKA.

Higher 2-Year Cumulative Incidence of Mental Health Disorders Following Irrigation and Debridement in Primary Lumbar Fusion.

Introduction: Spinal fusion is an operation that is employed to treat spinal diseases. Surgical site infection (SSI) after lumbar fusion (LF) is a postoperative complication. SSI is treated with irrigation and debridement (I&D), which requires readmittance following discharge or prolonged hospital stays, which are deleterious to patients' mental health.

Previous external beam radiation therapy for pelvic malignancy increases complications of total hip arthroplasty.

Introduction: External beam radiation therapy (EBRT) has known effects on bone health. No large database studies have looked at the effects of pelvic EBRT on total hip arthroplasty (THA) outcomes. The purpose of this study was to evaluate 90-day and long-term (>2 years) complication rates following THA in patients with a history of pelvic malignancy and EBRT.

Data-driven body mass index threshold associated with increased risk of 2-year periprosthetic joint infection following total shoulder arthroplasty.

Background: Body mass index (BMI) is a modifiable risk factor for medical and infectious complications following total shoulder arthroplasty (TSA). Previous studies investigating BMI were limited to the conventional classification system, which may be outdated for modern day patients. Therefore, the purpose of this study was to identify BMI thresholds that are associated with varying risk of 90-day medical complications and 2-year prosthetic joint infection (PJI) following TSA.
