High- versus low-viscosity cement vertebroplasty and kyphoplasty for osteoporotic vertebral compression fracture: a meta-analysis.

Background: To compare high- versus low-viscosity bone cement on the clinical outcomes and complications in patients with Osteoporotic vertebral compression fractures (OVCFs) who underwent percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP).

Methods: PubMed, Embase, and the Cochrane Library were searched for papers published from inception up to February 2021 for potentially eligible studies comparing high- versus low-viscosity cement for PVP/PKP. The outcomes were the leakage rate, visual analog scale (VAS), and Oswestry Disability Index (ODI).

Characteristics and correlation analysis of spino-pelvic sagittal parameters in elderly patients with lumbar degenerative disease.

Background: Retrospective analysis of the characteristics and correlation of spino-pelvic sagittal parameters in elderly patients with lumbar degenerative disease.

Methods: Eighty-seven patients with lumbar degenerative disease, with an average age of 75.4 years old, were enrolled in the observation group.

Bone cement distribution in the vertebral body affects chances of recompression after percutaneous vertebroplasty treatment in elderly patients with osteoporotic vertebral compression fractures.

Objective: Percutaneous vertebroplasty (PVP) is a surgical procedure that has been widely used to treat patients suffering from osteoporotic vertebral compression fractures (OVCFs). The procedure involves injection of bone cement into a fractured vertebra. In this study, we investigated whether the distribution of the cement in the vertebral body is related to the occurrence of recompression after surgery.

[Effects of different repair methods in treatment of supraspinatus tendon tear: experiment with rabbits].

Objective: To compare the effects of different repair methods in treatment of supraspinatus tendon tear.

Methods: Forty-five New Zealand rabbits aged 4 approximately 6 months underwent cutting off of the left supraspinatus tendon for the width of 8 mm, and then were randomly divided into 3 equal groups: Group A, undergoing suture anchor simple suture; Group B, undergoing suture anchor mattress suture; and Group C, undergoing transosseous mattress suture. Eight weeks after the operation the rabbits were killed.

[Evaluation of the postoperative quality of life in the elderly over 80 years old who underwent hip hemiarthroplasty for femoral neck fracture].

Objective: To evaluate the postoperative quality of life of aged patients (> 80 years old) who underwent hip hemiarthroplasty for femoral neck fracture one year ago.

Methods: From February 1995 to February 2001, 52 elderly patients (> 80 years old) underwent the hip hemiarthroplasty after femoral neck fractures. There were 28 males and 24 females, with the average age of 84.
