Predictions of the elastic modulus of trabecular bone in the femoral head and the intertrochanter: a solitary wave-based approach.

Biomech Model Mechanobiol 2021 Jun 10. Epub 2021 Jun 10.

Department of Civil Infrastructure and Environmental Engineering, Khalifa University of Science and Technology, Abu Dhabi, 127788, UAE.

This paper deals with the numerical prediction of the elastic modulus of trabecular bone in the femoral head (FH) and the intertrochanteric (IT) region via site-specific bone quality assessment using solitary waves in a one-dimensional granular chain. For accurate evaluation of bone quality, high-resolution finite element models of bone microstructures in both FH and IT are generated using a topology optimization-based bone microstructure reconstruction scheme. A hybrid discrete element/finite element (DE/FE) model is then developed to study the interaction of highly nonlinear solitary waves in a granular chain with the generated bone microstructures.

Normocalcemic Primary Hyperparathyroidism: Need for a Standardized Clinical Approach.

Endocrinol Metab (Seoul) 2021 Jun 1. Epub 2021 Jun 1.

Division of Endocrinology, Diabetes, Metabolism, and Nutrition, Mayo Clinic, Rochester, MN, USA.

Since normocalcemic primary hyperparathyroidism (NHPT) was first defined at the Third International Workshop on the Management of Asymptomatic Primary Hyperparathyroidism in 2008, many papers have been published describing its prevalence and possible complications. Guidelines for the management of this condition are still lacking, and making the diagnosis requires fulfillment of strict criteria. Recent studies have shown that intermittent oscillations of serum calcium just below and slightly above the normal limits are very frequent, therefore challenging the assumption that serum calcium must be consistently normal to make the diagnosis.

Cluster phenomenon of vertebral refractures after posterior pedicle screw fixation in a patient with glucocorticosteroid-induced Kümmell's disease: a treatment dilemma.

Arch Osteoporos 2021 Jun 8;16(1):93. Epub 2021 Jun 8.

Department of Orthopaedic Surgery, The Sixth Medical Center, General Hospital of PLA, 6# Fucheng Road, Haidian District, Beijing, 100048, China.

Introduction: Surgical treatments are usually preferred in patients with Kümmell's disease since it represents a failure of conservative treatment for osteoporotic vertebral compression fracture without evidence of spontaneous healing. However, the risk of postoperative refractures is much higher in patients with glucocorticosteroid-induced osteoporosis (GIOP) than in those with primary osteoporosis, possessing a therapeutic challenge and dilemma to orthopaedic surgeons.

Case Report: We described a rare cluster phenomenon of vertebral refractures in a patient with GIOP subsequent to segmental internal fixation for the initial management of glucocorticosteroid-induced Kümmell's disease, and a review of the literature. Read More

Anabolic actions of PTH in murine models: Two decades of insights.

J Bone Miner Res 2021 Jun 8. Epub 2021 Jun 8.

Department of Periodontics and Oral Medicine, University of Michigan School of Dentistry, 1011 North University Avenue, Ann Arbor, Michigan, 48109.

Parathyroid hormone (PTH) is produced by the parathyroid glands in response to low serum calcium concentrations where it targets bones, kidneys, and indirectly, intestines. The N-terminus of PTH has been investigated for decades for its ability to stimulate bone formation when administered intermittently (iPTH) and is used clinically as an effective anabolic agent for the treatment of osteoporosis. Despite great interest in iPTH and its clinical use, the mechanisms of PTH action remain complicated and not fully defined. Read More

The Male Athlete Triad-A Consensus Statement From the Female and Male Athlete Triad Coalition Part 1: Definition and Scientific Basis.

Clin J Sport Med 2021 Jun 3. Epub 2021 Jun 3.

Division of Sports Medicine and Non-Operative Orthopaedics, Departments of Family Medicine and Orthopaedic Surgery, University of California Los Angeles, Los Angeles, California; Department of Kinesiology, Penn State University, University Park, Pennsylvania; Department of Sports Medicine and Nutrition, University of Pittsburgh, Pittsburgh, Pennsylvania; Division of Pediatric Endocrinology, Massachusetts General Hospital and Harvard Medical School, Boston, Massachusetts; Department of Orthopaedic Surgery, Stanford University, Stanford, California; Department of Family and Consumer Sciences, California State University, Long Beach, Long Beach, California; and Intermountain Healthcare, Salt Lake City, Utah.

Abstract: The Male Athlete Triad is a syndrome of 3 interrelated conditions most common in adolescent and young adult male endurance and weight-class athletes and includes the clinically relevant outcomes of (1) energy deficiency/low energy availability (EA) with or without disordered eating/eating disorders, (2) functional hypothalamic hypogonadism, and (3) osteoporosis or low bone mineral density with or without bone stress injury (BSI). The causal role of low EA in the modulation of reproductive function and skeletal health in the male athlete reinforces the notion that skeletal health and reproductive outcomes are the primary clinical concerns. At present, the specific intermediate subclinical outcomes are less clearly defined in male athletes than those in female athletes and are represented as subtle alterations in the hypothalamic-pituitary-gonadal axis and increased risk for BSI.
