Background: This study aims to demonstrate the 3-dimensional pattern of the nutrient vessels of the triquetrum using micro-computed tomography and determine the safe region for screw applications to the bone.
Methods: Seven fresh frozen cadavers' ulnar and radial arteries were injected with Microfil MV-117. Triquetral bones were dissected and examined using micro-computed tomography.
Posterior interosseous artery distal ulna graft for management of radius nonunion: Technique and case report.

Distal radius fracture nonunion can result in significant deformity, loss of function, and chronic pain. Presented here is a case of distal radius nonunion that was surgically reconstructed with a pedicled distal ulna bone graft based on the periosteal branches of the posterior interosseus artery (PIA). This technique has limited prior utilization for adult distal radius nonunion treatment but offers an effective option for surgical reconstruction of distal radius nonunion with preservation of the radiocarpal joint, utilizing a less invasive surgery that also reduces hospitalization stay.

From the Department of Anesthesia, Perioperative and Pain Medicine, Lahey Hospital and Medical Center, Burlington, Massachusetts.
After vascular puncture and catheterization, arteries can have many complications that impede blood flow such as vasospasm, thrombosis, and emboli generation, among other complications. Treatment depends on severity of ischemic symptoms and can range from as mild as applying local heat packs to surgical thrombectomy. We present a case of digital ischemia secondary to vascular puncture that was successfully treated with a supraclavicular nerve block, resulting in the vascular surgery team canceling an emergent surgery.

To evaluate the association of anti-IFI16 antibodies with peripheral vasculopathy and the predictive value of anti-IFI16 antibodies for the development or persistence of digital ulcers (DPDU) in SSc. A total of 42 SSc patients and 42 age- and sex-matched healthy controls were enrolled. Anti-IFI16 antibodies were examined by ELISA.

Ulnar artery aneurysms are extremely rare and are mainly associated with hypothenar hammer syndrome, an ischemic disorder of the hand resulting from mechanical and repetitive trauma to the hypothenar region. The ulnar artery is hit against the hook of the hamate bone, causing damage to the vessel wall and leading to occlusion or formation of an aneurysm. We describe the case of a truck driver who underwent resection of an ulnar artery aneurysm in the right hand and reconstruction using end-to-end anastomosis with no complications or recurrence.
