AI Article Synopsis
- The study aimed to evaluate the effectiveness of percutaneous kyphoplasty (PKP) using an improved injecting tube through a single puncture site for treating osteoporotic vertebral compression fractures.
- During the research period, 60 cases were analyzed, with one group using a routine injecting tube and the other using an improved version, showing no significant differences in key preoperative metrics or complication rates.
- Results indicated that while both methods improved postoperative outcomes like pain and vertebral height, the improved injecting tube offered better bone cement distribution, suggesting it could be a more effective option without increasing operation time or complication risks.
Article Abstract
Objective: To research the feasibility and effectiveness of percutaneous kyphoplasty (PKP) by improved injecting tube through unipedicular puncturing.
Methods: Between January 2012 and Junuary 2016, 60 cases (68 vertebrae) of osteoporotic vertebral compression fractures (OVCF) were treated. PKP was performed through unipedicular puncturing with routine injecting tube in 30 cases (34 vertebrae, routine group), and with improved injecting tube in 30 cases (34 vertebrae, improved group). There was no significant difference in age, gender, disease duration, fracture level, preoperative visual analogue scale (VAS), or vertebral height between 2 groups ( >0.05). The operation time, the volume of bone cement injected, preoperative and postoperative VAS, and preoperative and postoperative vertebral height, and postoperative distribution coefficient of bone cement were recorded and compared between 2 groups.
Results: Good healing of puncture points was achieved in 2 groups after PKP, and no serious complication occurred. There was no significant difference in operation time and the volum of bone cement injected between 2 groups ( =0.851, =0.399; =1.672, =0.101). Bone cement leakage was observed in 2 cases of 2 groups respectively. The distribution coefficient of bone cement in routine group was significantly less than that in improved group ( =13.049, =0.000). All patients were followed up 12-36 months (mean, 19 months). The postoperative VAS and vertebral height were significantly improved when compared with preoperative ones in 2 groups ( <0.05), but there was no significant difference in VAS between at 2 days after operation and at last follow-up, in vertebral height between at 2 days after operation and at 1 year after operation, and between 2 groups after operation ( >0.05). X-ray films showed vertebral compression fractures in 6 cases of routine group and in 1 case of improved group during follow-up.
Conclusion: PKP by improved injecting tube through unipedicular puncturing can improve the distribution of bone cement, restore the height and strength of vertebral body, and reduce the incidence of re-fracture.

Introduction: Implantology has become a primary solution for tooth loss due to excellent osseointegration and high long-term success rates. However, complications such as abutment screw loosening, especially in implant-supported single crowns, compromise prosthesis longevity. Anaerobic adhesives (AAs) have shown promise in mechanical fields for preventing screw loosening, but their effectiveness in dental implants, particularly zirconia, remains uncertain.

Background: Limitations to using the knee as donor cartilage include cartilage thickness mismatch and donor site morbidity. Using the radial head as donor autograft for capitellar lesions may allow for local graft harvest without distant donor site morbidity. The purpose of this study is to demonstrate the feasibility of performing local osteochondral autograft transfer from the nonarticular cartilaginous rim of the radial head to the capitellum.

Background: Prone lateral spinal surgery for simultaneous lateral and posterior approaches has recently been proposed to facilitate surgical room efficiency. The purpose of this study is to evaluate the feasibility and outcomes of minimally invasive prone lateral spinal surgery using a rotatable radiolucent Jackson table.
Methods: From July 2021 to June 2023, a consecutive series of patients who received minimally invasive prone lateral spinal surgery for various etiologies by the same surgical team were reviewed.
Background: Kyphoplasty (KP) is a well-established procedure with a low complication risk, however, the procedure's safety in patients with comorbidities and in the setting of systemic infection remains uncertain with no clear guidelines. We present a unique case of KP in the setting of recurrent septicemia, which required subsequent salvage vertebrectomy.
