AI Article Synopsis
- The study compared the effects of teriparatide (TPTD) and zoledronic acid (ZOL) on bone healing and spinal fusion in osteoporosis patients after lumbar surgery.
- Results showed that TPTD treatment led to greater improvements in bone mineral density and bone formation markers than ZOL over 12 months, with TPTD also demonstrating a higher fusion rate at that time.
- The conclusion highlighted that TPTD is more effective than ZOL for enhancing bone formation and spinal fusion in patients with osteoporosis undergoing transforaminal lumbar interbody fusion (TLIF).
Article Abstract
Purpose: The research aimed to compare the therapeutic effect of teriparatide (TPTD) and zoledronic acid (ZOL) therapy on bone formation and spinal fusion in patients with osteoporosis (OP) who underwent transforaminal lumbar interbody fusion (TLIF).
Methods: On the basis of different anti-OP treatment options, the TPTD group was treated daily with TPTD (20 μg. ih. qd) for at least 6 months, while the ZOL group was treated with a single dose of ZOL (5 mg. ivgtt. st) postoperatively. The visual analogue scale (VAS), Oswestry Disability Index (ODI), bone mineral density (BMD), and concentration of bone turnover markers before, 6, and 12 months after surgery were evaluated. X-ray and three-dimensional computed tomography scans were performed at 6 and 12 months postoperatively to assess interbody fusion.
Results: The number of patients in the TPTD and ZOL groups was 29 and 38 patients, respectively. The VAS and ODI scores in both groups were significantly reduced at 6 and 12 months after TLIF. Compared with that of baseline, the lumbar spine BMD of TPTD patients increased significantly from 0.716±0.137 g/cm to 0.745±0.124 g/cm and 0.795±0.123 g/cm at 6 and 12 months, respectively, and was significantly higher than that of the ZOL group at 12 months (0.720±0.128 g/cm). The bone formation marker, P1NP, in the TPTD group increased significantly (145.48±66.64 ng/mL and 119.55±88.27 ng/mL) compared with baseline (44.67±25.15 ng/mL) and in the ZOL group (28.82±19.76 ng/mL and 29.94±20.67 ng/mL) at 6 and 12 months, respectively. The fusion rates in the TPTD and ZOL groups were 57% and 45% at 6 months, without statistical significance. However, TPTD had a more statistically significant positive influence on fusion rate than ZOL at 12 months (86% vs 70%).
Conclusion: TPTD was more efficient than ZOL in bone formation and spinal fusion in OP patients who underwent TLIF.

In anterior cruciate ligament (ACL) repair methods, the continuous enzymatic erosion of synovial fluid can impede healing and potentially lead to repair failure, as well as exacerbate articular cartilage wear, resulting in joint degeneration. Inspired by the blood clot during medial collateral ligament healing, we developed a composite scaffold comprising collagen (1 %, w/v) and polyvinyl alcohol (5 %, w/v) combined with platelet-rich plasma (PRP). The composite scaffold provides a protective barrier against synovial erosion for the ruptured ACL, while simultaneously facilitating tissue repair, thereby enhancing the efficacy of ACL repair techniques.

Periodontitis, a common chronic inflammatory condition caused by bacteria, leads to loss of attachment, resorption of alveolar bone, and ultimately tooth loss. Therefore, reducing bacterial load and fostering alveolar bone regeneration are essential components in the treatment of periodontitis. In this study, we prepared smaller-sized Ag-Metal Organic Frameworks (Ag@MOF) and loaded with sodium alginate (Alg) hydrogel for periodontitis treatment.

Obesity is a major public health issue worldwide. Despite various approaches to weight loss, the most effective technique for reducing obesity, as well as diabetes and associated diseases, is bariatric surgery. Increasingly, young women without children are undergoing bariatric surgery, vertical sleeve gastrectomy (VSG) being the most common procedure nowadays.

Background: Low-intensity pulsed ultrasound (LIPUS) has been used as an effective noninvasive method for treating fractures and osteoarthrosis, but the application in the field of oral implantation is in its infancy. This study aimed to clarify the effect and mechanism of LIPUS on the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and implant osseointegration, and to provide an experimental basis for future clinical applications.
Methods: Dental implants were inserted into Wistar rat femurs, and LIPUS was performed for 4 weeks.
