Prevalence of Upper Extremity Volleyball Injuries Within Different Adult Age Groups: A Comprehensive Analysis of National Data From 2013-2022.

Background: The mean age of volleyball athletes has increased over the past decade, raising concerns about musculoskeletal injuries. There is no literature on how different mechanisms of injury (MOI) affect different adult age groups.

Purpose: To evaluate epidemiologic trends, diagnoses, and mechanisms of volleyball-related upper extremity injuries within different adult age groups.

Lower Extremity Surfing Injuries Seen at United States Emergency Departments From 2002 to 2022.

Background: Surfing is an increasingly popular sport with a high propensity for both traumatic and atraumatic injuries.

Purpose: To analyze the trends, etiologies, and diagnoses of lower extremity orthopaedic-related surfing injuries presenting to United States (US) emergency departments (EDs) within a 21-year study period.

Study Design: Descriptive epidemiology study.

Decreasing Trend in Upper Extremity Surfing Injuries Presenting to United States Emergency Departments - A 20-Year Analysis.

Surfing is a globally popular recreational sport with limited epidemiologic data. Currently, there is a paucity of literature regarding injury profiles and mechanisms of orthopaedic-related injuries. This study analyzed trends, etiologies, and diagnoses of upper extremity orthopaedic-related surfing injuries presenting to United States (US) emergency departments.

What's New in Geriatric Acetabular Fractures.

The incidence of acetabular fractures in the geriatric population is growing, yet the optimal treatment algorithm remains a controversial topic among orthopaedic surgeons. This review highlights key studies published over the past 5 years on the outcomes of various treatment options for geriatric acetabular fractures. Topics include surgical timing, mortality and risk factors, nonoperative treatment, open reduction internal fixation, and acute total hip arthroplasty.

Characteristics, Treatments, and Outcomes of Tibial Plateau Nonunions: A Systematic Review.

Background: Due to the rare incidence of tibial plateau nonunions, current studies are limited to small sample sizes and patient demographics. The aim of this systematic review is to quantify and report patient and fracture traits, possible risk factors, and treatment outcomes of tibial plateau nonunions

Methods: PubMed, Clinical Key, and MEDLINE were searched for articles published prior to August 2020 in accordance to the preferred reporting items for systematic reviews and meta-analyses (PRISMA). The authors used varying combinations of the following terms to identify relevant articles: "tibial," "plateau," "nonunion," "non-union.

Denosumab-Associated Peri-Implant Atypical Femur Fracture: A Case Report.

Bisphosphonate use has been associated with atypical pathologic fracture and slowed bone turnover. We present a case of a bisphosphonate-associated peri-implant atypical femur fracture following use of a recon nail for treatment of a prior bisphosphonate-associated atypical femur fracture.

Implementing Regional Nerve Blocks in Hip Fracture Programs: A Review of Regional Nerve Blocks, Protocols in the Literature, and the Current Protocol at The Queen's Medical Center in Honolulu, HI.

Hip fractures are a common cause of acute pain in elderly patients. However, pain may be undertreated due medical comorbidities. Strong evidence supports the use of regional nerve blocks to reduce preoperative pain after hip fracture.

A Comparison of Skeletal Injuries Arising from Moped and Motorcycle Collisions.

Motorcycle and moped injuries remain a significant cause of motor-vehicle related morbidity and mortality. There is a paucity of literature describing the skeletal injuries of moped riders and how these compare to those of motorcyclists, however. This study seeks to examine the skeletal injuries sustained in such incidents and determine if there are significant differences.

Closed treatment of overriding distal radial fractures without reduction in children.

Background: Traditionally, distal radial fractures with marked displacement and angulation have been treated with closed or open reduction techniques. Reduction maneuvers generally require analgesia and sedation, which increase hospital time, cost, patient risk, and the surgeon's time. In our study, a treatment protocol for pediatric distal radial fractures was used in which the fracture was left shortened in an overriding position and a cast was applied without an attempt at anatomic fracture reduction.

Inhibition of simian/human immunodeficiency virus replication in CD4+ T cells derived from lentiviral-transduced CD34+ hematopoietic cells.

We examined the ability of a HIV-1-based vector (VRX494) encoding a 937-bp antisense HIV-1 envelope sequence to inhibit the replication of chimeric SIV/HIV-1 viruses encoding the HIV-1 envelope. Challenge of VRX494-transduced CEMx174 cells resulted in potent inhibition of HIV-1 and several SHIV strains. To evaluate the potential efficacy of the VRX494 vector for stem cell gene therapy, rhesus CD34(+) bone marrow cells were transduced with VRX494 and then cultured on thymus stroma to induce T cell differentiation.
