Male osteoporosis is primarily caused by a decrease in testicular testosterone production. Male osteoporosis remains a disease with insufficient diagnosis and treatment, and its consequences are severe, especially in older patients. The gut microbiota plays a crucial role in its occurrence and development.

Improving the regeneration of the tendon-bone interface (TBI) helps to decrease the risk of rotator cuff retears after repair surgeries. Unfortunately, the lack of inherent healing capacity of the TBI, insufficient mechanical properties, and abnormal and persistent inflammation during repair are the key factors leading to suboptimal healing of the rotator cuff. Therefore, a high-strength rotator cuff repair material capable of regulating the unbalanced immune response and enhancing the regeneration of the TBI is urgently needed.

Orthopaedic Surgery in the Jehovah's Witness Patient: Clinical, Ethical, and Legal Considerations.

J Bone Joint Surg Am

January 2025

Department of Orthopedic Surgery, Warren Alpert Medical School, Brown University, Providence, Rhode Island.

➢ Jehovah's Witnesses refuse allogeneic blood products based on religious beliefs that create clinical, ethical, and legal challenges in orthopaedic surgery, requiring detailed perioperative planning and specific graft selection.➢ Detailed perioperative planning is particularly important for procedures with high intraoperative blood loss.➢ Graft selection must align with Jehovah's Witnesses patients' religious beliefs, with options including autografts, allografts, and synthetic materials; this requires shared decision-making between the patient and surgeon.

Background: An accurate knowledge of a patient's risk of cord-level intraoperative neuromonitoring (IONM) data loss is important for an informed decision-making process prior to deformity correction, but no prediction tool currently exists.

Methods: A total of 1,106 patients with spinal deformity and 205 perioperative variables were included. A stepwise machine-learning (ML) approach using random forest (RF) analysis and multivariable logistic regression was performed.

Thoracolumbar Fracture: A Natural History Study of Survival Following Injury.

J Bone Joint Surg Am

November 2024

Department of Orthopaedic Surgery, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts.

Background: Fractures of the thoracic and lumbar spine are increasingly common. Although it is known that such fractures may elevate the risk of near-term morbidity, the natural history of patients who sustain such injuries remains poorly described. We sought to characterize the natural history of patients treated for thoracolumbar fractures and to understand clinical and sociodemographic factors associated with survival.

Background: Rotator cuff repair (RCR) is a frequently performed outpatient orthopaedic surgery, with substantial financial implications for health-care systems. Time-driven activity-based costing (TDABC) is a method for nuanced cost analysis and is a valuable tool for strategic health-care decision-making. The aim of this study was to apply the TDABC methodology to RCR procedures to identify specific avenues to optimize cost-efficiency within the health-care system in 2 critical areas: (1) the reduction of variability in the episode duration, and (2) the standardization of suture anchor acquisition costs.

Background: Risk factors for gluteal tears include age-related deterioration, female sex, and increased body mass index. As the literature that supports the sagittal relationship between the lumbar spine and the hip is increasing, there may be a parallel relationship between the perturbations in spinopelvic alignment caused by lumbar spine disease and gluteal muscle tears. Because no prior studies other than single-institution series have reported on this phenomenon, we investigated spine-abductor syndrome at the population level.

Introduction: The use of corticosteroid injections for short-term pain relief for knee osteoarthritis can have deleterious adverse effects. Amniotic tissue has shown promise in vitro; therefore, this study compared a morcellized injectable amniotic tissue allograft to corticosteroid injection.

Methods: Eighty-one patients with symptomatic severe knee osteoarthritis (Kellgren-Lawrence grade 3 to 4) were prospectively randomized to either a double-blinded single injection of BioDRestore (Integra LifeSciences; n = 39) or triamcinolone acetonide (n = 42).

» Patients with diabetes mellitus (DM) undergoing shoulder arthroplasty (SA) have a unique risk profile, which must be considered by clinicians.» The presence of DM as a comorbidity is associated with longer length of stay following SA, greater likelihood of nonhome discharge, and a higher rate of 90-day readmission.» Though the incidence is low, patients with DM are at an increased risk of serious postoperative cardiovascular complications, such as pulmonary embolism, venous thromboembolism, and myocardial infarction.

Background: Iliopsoas injuries are a common cause of anterior hip and groin pain and can be successfully managed with conservative treatment. Corticosteroid and local anesthetic injections can also be offered in conjunction with nonoperative management. Given the variability in reported injection guidelines, composition, and techniques, the purpose of this study was to systematically review the literature to assess progression to surgery and patient outcomes following iliopsoas injections.

The prevalence of childhood obesity is increasing worldwide, along with the associated common comorbidities of type 2 diabetes and cardiovascular disease in later life. Motivated by evidence for a strong genetic component, our prior genome-wide association study (GWAS) efforts for childhood obesity revealed 19 independent signals for the trait; however, the mechanism of action of these loci remains to be elucidated. To molecularly characterize these childhood obesity loci, we sought to determine the underlying causal variants and the corresponding effector genes within diverse cellular contexts.

Introduction: Vascular injury during acetabular screw fixation is a life-threatening complication of total hip arthroplasty. This study uses three-dimensional computed tomography to (1) measure absolute distance from the external iliac artery (EIA) to the acetabulum, (2) determine available bone stock along the EIA path, and (3) create a novel acetabular vascular risk map.

Methods: A retrospective radiographic study was conducted using three-dimensional CT.

J Am Acad Orthop Surg

November 2024

From the Department of Orthopaedics, West Virginia University, Morgantown, WV (Sraj and Farley), and Department of Surgery, Division of Plastic Surgery, West Virginia University, Morgantown, WV (Turner and Woodberry).

Orthopaedic surgeons encounter tattoos in surgical fields with an increasing frequency and have the choice of avoiding, disregarding, bordering, or incorporating them into the surgical incisions. This article describes the history and the personal, social, and artistic value of tattoos; the physiology of tattoos and wound healing; the principles of incision planning for optimal cosmesis; and specific considerations when encountering tattoos in the surgical field. It subsequently describes cosmetic outcomes and tattoo-specific complications after surgery and provides a decision tree to help surgeons and patients decide the best approach for individual situations.

Benign Bone Tumors of the Hand: Beyond Enchondromas.

J Am Acad Orthop Surg

November 2024

From the Department of Orthopedic Surgery, SUNY Upstate Medical University, Syracuse, NY (Albanese, Lynch, and Damron), and the Department of Orthopaedic Surgery, Virginia Commonwealth University, Richmond, VA (Eswaran).

Beyond enchondromas, the most common bone tumors of the hand, there are numerous less common benign bone tumors and mimickers with which orthopaedic and hand surgeons should be familiar. These include other benign cartilage tumors, cystic lesions, osteogenic tumors, giant cell tumor, and fibrous dysplasia. Particularly unique lesions include bizarre parosteal osteochondromatous proliferation (Nora lesion), florid reactive periostitis, turret exostosis (acquired osteochondroma), giant cell reparative granuloma (solid aneurysmal bone cyst), and epidermoid cyst.
