Improvement in Pain and Quality of Life After Ultrasound-Guided Saphenous Nerve Block in Patients With Knee Osteoarthritis.

Cureus 2022 May 16;14(5):e25060. Epub 2022 May 16.

Radiology, Vardhman Mahavir Medical College and Safdarjung Hospital, Delhi, IND.

Introduction Osteoarthritis (OA) of the knee is a common complaint in the elderly population and results in considerable disability in advanced stages. Though many pharmacological, electrotherapeutic, and interventional options are available for the effective treatment of knee OA in the early stages, these modalities fail to provide effective and long-term relief in some cases where peripheral nerve blocks may prove beneficial. Hence, this study was conducted to assess the efficacy of the saphenous nerve block in knee pain due to OA. Read More

Ultrasound-Guided Saphenous Nerve Block in Rabbits (): A Cadaveric Study Comparing Two Injectate Volumes.

Animals (Basel) 2022 03 1;12(5). Epub 2022 Mar 1.

Southern Counties Veterinary Specialists (SCVS), Forest Corner Farm, Hangersley, Hampshire, Ringwood BH24 3JW, UK.

Ultrasound-guided (US-guided) loco-regional anesthesia techniques allow direct visualization and blockade of sensory nerves. The saphenous nerve (SN), a terminal branch of the femoral nerve (FN), is strictly a sensory nerve for which electrical locator devices are ineffective for localization as no effector muscle contractions can be evoked. US-guided SN block in species other than rabbits produces hind-limb analgesia without affecting FN motor function. Read More

Overview of the Innervation of Ankle Joint.

Phys Med Rehabil Clin N Am 2021 11 14;32(4):791-801. Epub 2021 Jul 14.

Division of Anatomy, Department of Surgery, Temerty Faculty of Medicine, University of Toronto, 1 King's College Circle, Room 1158, Toronto, ON M5S 1A8, Canada.

In this article, the literature describing the origin, course, and termination of the nerves innervating the ankle joint is reviewed and discussed. The anterior aspect of the joint capsule receives innervation from articular branches from the saphenous, superficial, and deep fibular nerves; laterally from the sural and superficial fibular nerves; and medially and posteriorly from the saphenous and tibial nerves. Comprehensive mapping of the trajectory, spatial relationships, and termination of the articular branches innervating the ankle joint capsule will aid in developing new and improving existing image-guided nerve block and radiofrequency ablation protocols to treat chronic joint pain.

Transposition of the superficial femoral artery combined with ultrasound-guided returning-venous cannulation as a last resort for vascular access in a multi-complicated hemodialysis patient.

J Vasc Access 2021 Jun 6:11297298211023288. Epub 2021 Jun 6.

Department of Surgery, Saiwaicho Memorial Hospital, Okayama, Japan.

A superficialized artery as a blood-drawing route could be an option for vascular access (VA) in hemodialysis patients with cardiac failure, vessel damage, steal syndrome, and venous hypertension, and it could be a secondary VA option in those with repetitive vascular access troubles, routinely requiring a blood-returning venous route. The brachial artery is preferably used for superficialization due to the benefit of its appropriate diameter for cannulation, procedural ease of surgery under local anesthesia, and usable subcutaneous vein for blood-returning route in the upper limb. The superficial femoral artery (SFA) has also been reported as a candidate for arterial transposition; however, its subcutaneous transposition could have difficulties in requiring general anesthesia and securing blood-inflow-venous routes.
