Background: The continuity of arteriovenous fistula (AVF) patency is essential for effective hemodialysis. In the present study, we aimed to investigate the relationship between AVF patency and atherogenic index of plasma (AIP) in patients with native proximal upper-extremity AVF.
Methods: A total of 143 patients with native proximal upper-extremity AVF created in our clinic between January 2014 and April 2022 were analyzed retrospectively. Those with at least 24 months of follow-up and intact AVF were defined as "Group 1" ( = 97), and those with AVF thrombosis were defined as "Group 2" ( = 46).
Results: The primary patency rates of the patient groups included in the study were found to be 88.1% at 6th month, 79% at 12th month, and 67.8% at 24th month. The mean AIP values that were calculated in Group 2 were found to be statistically significantly higher than the mean value calculated in Group 1 (0.30 ± 0.12 vs 0.20 ± 0.10, < 0.001). In a multivariate logistic regression analysis made to identify the predictors of proximal upper-extremity AVF thrombosis development, total cholesterol (OR [odds ratio] = 2.259, 95% CI [confidence interval] = 1.468-3.475, < 0.001), and triglyceride (OR = 13.777, 95% CI = 3.740-50.750, < 0.001) were identified as independent predictors.
Conclusion: A significant relationship was detected in the analyses between the easily calculated AIP values and the development of AVF thrombosis. The AIP is a remarkable preoperative parameter regarding proximal upper-extremity AVF patency.

Extensor tendon injuries are commonly encountered after trauma. These injuries often result in acute weakness and have widely differing treatment options depending on the severity and the location of the injury within the upper extremity. Zone I injuries can often be treated nonoperatively with the potential for pinning of any large bony avulsion fragments.

Article Synopsis
- Fractures of the proximal ulna and radial head often arise from falls or direct impacts, affecting elbow stability and function with symptoms like pain and limited motion.
- The common clinical scenario involves radial head dislocation accompanied by a proximal ulna fracture, known as a Monteggia fracture-dislocation.
- This study examines the surgical treatment of a patient with these fractures and their subsequent physical therapy follow-up.
Superficial palmar branch of radial artery flap for digital skin reconstruction: anatomical study and clinical applications.
Surg Radiol Anat

Faculty of Medicine, Dokuz Eylul University, Izmir, Turkey.
Article Synopsis
- The study examines the superficial palmar branch of the radial artery (SUPBRA) to improve techniques for reconstructing palmar skin, focusing on its anatomy and harvesting methods.
- Researchers dissected 19 male hand specimens to gather detailed anatomical data, including dimensions and positions of key structures related to SUPBRA, analyzing how best to utilize this flap in reconstruction efforts.
- Results indicated that the SUPBRA has adequate dimensions for viability in surgical applications, with specific measurements and the identification of critical vascular contributions that ensure successful use in cases of hand injury.
Dorsoradial ligament reconstruction versus imbrication for restoring trapeziometacarpal joint stability: a comparative biomechanical study.

Department of Orthopedic Surgery, Yonsei University College of Medicine, Seoul, South Korea.
The unique saddle articulation of the trapeziometacarpal joint allows for a wide range of motion necessary for routine function of the thumb. Inherently unstable characteristics of the joint can lead painful instability. In this study, we modified a surgical dorsal ligament reconstruction technique for restoring trapeziometacarpal joint stability.

Background: Open and crushed forearm injury is a complex and rare injury affecting the upper extremity. It results in damage to various structures, including bones, soft tissues, and neurovascular bundles, ultimately leading to functional impairment. Typically, these injuries occur owing to high-energy trauma.
