Zoledronate, alendronate, risedronate, etidronate, ibandronate, parathyroid hormone, denosumab and selective estrogen receptor modulators had significant secondary prevention effects on OVCF. Moderate quality evidence proved romosozumab had better effect than alendronate. High quality evidence proved PTH had better effect than risedronate, but with higher risk of adverse events.

Among medical education institutions worldwide, the time allotted for anatomy instruction has decreased without any reasonable time optimization suggestions. In addition, the utility of cadaver dissection has long been debated. Herein, we surveyed students' perceptions of anatomy education with respect to time and hands-on cadaver dissection, at Seoul National University College of Medicine. With the help of a questionnaire, we surveyed third- and fourth-year students at our institute who had co

Highly porous calcium phosphate (CaP) scaffolds with multiple phases were fabricated through combination of material extrusion type 3D printing process, salt-leaching, and bone cement chemistry under physiological conditions. Scaffolds with nano-sized calcium deficient hydroxy apatite (CDHA) in the core and large crystals of dicalcium phosphate dihydrate (DCPD or brushite) on the outer surface were fabricated by immersing the 3D ceramic scaffold in aqueous ‘cement solution’. In contrast to conve

The prevalence of OVCFs in the thoracolumbar junction rapidly increases with old age and low BMD in Korean postmenopausal women. Femur and total hip BMD are more predictive of thoracolumbar junction fractures than lumbar spine BMD. Patients with radiologic OVCFs had a significantly lower quality of life than no OVCF group. Therefore, this study shows it is important to treat and prevent osteoporosis before an OVCF occurs.

Although progression of hPTRCT in the long term is uncertain, after 1-year follow-up with MRI, tears progressed in 16% of the tears in this study. Furthermore, some tears were healed or reduced in size, which indicates that decisions to undertake surgical repair at time of presentation may be excessive.

Radial wedge osteotomy yielded excellent radiological and functional outcomes in advanced stages of Kienböck's disease and these results were comparable to those of Lichtman stage IIIA disease. This technique could be a useful alternative to salvage procedures in the treatment of Lichtman stage IIIB/IV Kienböck's disease without severe radiocarpal arthritis.

PMMA bone cement is commonly used in the field of orthopedics as a filling material. However, due to the lack of biological activity and high elastic modulus, its application scope and efficacy are greatly limited, such as in the treatment of osteoporotic vertebral compression fractures(OVCF). For this reason, new functional bone cement was synthesized and designed to address and improve those shortcomings. In this study, Tetracalcium phosphate (TTCP) and Whitlockite (WH) were incorporated with

Patients with high LM and mild FI ratio observed on preoperative MRI demonstrated more favorable clinical and radiographic outcomes after lumbar interbody fusion. Therefore, preoperative paraspinal muscle condition should be considered when planning lumbar interbody fusion.

Postmenopausal women are liable to have osteoporotic fractures due to the high prevalence of osteoporosis, a history of falling, and the comorbidity with diseases that restrict ambulation. A better understanding of postmenopausal women in the orthopedic outpatient settings is important to the management of osteoporotic fractures.

Whitlockite had a potential of being a better bone substrate hydroxyapatite and tricalcium phosphate in spinal fusion with low risk of inducing ectopic ossification.

The fusion quality of E.BMP-2/HA was superior to that of AIBG. E.BMP-2/HA showed comparable mid-term outcomes to that of AIBG in terms of efficacy and safety in one-level lumbar PLF surgery.

This new 3D scanner has some strengths like radiation-free methods, correlation with x-ray parameters and clinical symptoms, independence to body composition data, and possibility of analyzing dynamic spine balance.

This study demonstrated that the IEI is related to BTMs regardless of BMD in misTLIF. In addition, the P1NP/CTX ratio or subtypes could be helpful in predicting the risk of IEI due to the parallel dynamics of BTMs.

Quality of repair, measured as the extent of postoperative GT coverage at the time of surgery, was associated with clinical and structural outcomes after rotator cuff repair surgery.
