Inhibition of miR-93-5p promotes osteogenic differentiation in a rabbit model of trauma-induced osteonecrosis of the femoral head.

FEBS Open Bio 2021 Jun 6. Epub 2021 Jun 6.

Medical Center of Hip, Luoyang Orthopedic-Traumatological Hospital (Orthopedics Hospital of Henan Province), 471002, Henan Province, China.

Trauma-induced osteonecrosis of the femoral head (TIONFH) is characterized by femoral head collapse accompanied by degenerative changes of the hip. We previously reported that miR-93-5p expression is abnormally high in TIONFH patients, but the role of miR-93-5p in the TIONFH process remains unclear. Herein, we investigated the role of miR-93-5p in TIONFH in a rabbit model. Read More

Update on Rare Adverse Events from Osteoporosis Therapy and Bisphosphonate Drug Holidays.

Robert A Adler

Endocrinol Metab Clin North Am 2021 Jun 28;50(2):193-203. Epub 2021 Apr 28.

Endocrinology and Metabolism Section, Central Virginia Veterans Affairs Health Care System, Richmond, VA, USA; Division of Endocrinology, Virginia Commonwealth University, Richmond, VA, USA. Electronic address:

Bisphosphonates remain a first-line treatment for osteoporosis and decrease vertebral and hip fractures without side effects in most patients. With extended treatment, osteonecrosis of the jaw and atypical femoral fracture occur rarely, but fear of side effects has led to not starting or discontinuing treatment. Atrial fibrillation and uveitis are less appreciated by the general public, but their rare incidence must be recognized. Read More

Injury 2021 May 2. Epub 2021 May 2.

Duke University Hospital, Department of Orthopaedic Surgery, 2310 Erwin Road, Durham, NC 27710, USA. Electronic address:

Introduction: Osteonecrosis of the femoral head (ONFH) can occur after traumatic injuries of the hip. Surgical treatment with total hip arthroplasty (THA) may not produce lifelong viability in younger patients. Free vascularized fibular graft (FVFG) has become a reliable method to delay or even avoid THA in this patient population by aiming to correct loss of viable bone through vascularized autologous bone transfer.

Lack of Conclusive Evidence of the Benefit of Biologic Augmentation in Core Decompression for Nontraumatic Osteonecrosis of the Femoral Head: A Systematic Review.

Arthroscopy 2021 May 5. Epub 2021 May 5.

Department of Orthopaedics, Balgrist University Hospital, Zurich, Switzerland.

Purpose: To assess whether biologic augmentation in addition to core decompression (CD), compared with CD alone, improves clinical and radiographic outcomes in the treatment of nontraumatic osteonecrosis of the femoral head (ONFH). Our hypothesis was that biologic augmentation would reduce the progression of osteonecrosis and therefore also the rate of conversion to total hip arthroplasty (THA).

Methods: A systematic review was performed in accordance with the Preferred Reporting Items of Systematic Reviews and Meta-analysis (PRISMA) statement. Read More
