Ultrasound-guided interscalene brachial plexus blockade (IBPB) has a relatively high success rate in shoulder surgery; however, whether multiple injections are superior to a single injection (SI) is currently unknown. In the present study, ultrasound-guided SI and triple-injection (TI) IBPBs were compared in a prospective randomized trial. A total of 111 patients undergoing arthroscopic shoulder surgery and presenting with an American Society of Anesthesiologists physical status grading of I-II were randomly allocated to receive IBPB with 15 ml of 1% ropivacaine as a SI or TI...

The canonical Wnt/β-catenin pathway is a highly conserved signaling cascade that plays critical roles during embryogenesis. Wnt ligands regulate axonal extension, growth cone guidance and synaptogenesis throughout the developing central nervous system (CNS). Recently, studies in mammalian and fish model systems have demonstrated that Wnt/β-catenin signaling also promotes axonal regeneration in the adult optic nerve and spinal cord after injury, raising the possibility that Wnt could be developed as a therapeutic strategy...

PURPOSE: The aim of this study was to identify the effects of fascia penetration on superficial radial sensory nerve action potential amplitude. METHODS: The penetration point (PP) at which the nerve penetrated the brachioradialis fascia and became superficial was observed using ultrasonography. The sensory nerve action potential amplitude was measured at five points: the penetration point, 2 and 4 cm proximal to the PP, and 2 and 4 cm distal to the PP. RESULTS: The sensory nerve action potential amplitude at the penetration point and at 2 and 4 cm distal to the PP was significantly larger than that at 2 and 4 cm proximal to the PP...

Background: Brittle stars (Ophiuroidea, Echinodermata) have been increasingly used in studies of animal behavior, locomotion, regeneration, physiology, and bioluminescence. The success of these studies directly depends on good working knowledge of the ophiuroid nervous system. Results: Here, we describe the arm nervous system at different levels of organization, including the microanatomy of the radial nerve cord and peripheral nerves, ultrastructure of the neural tissue, and localization of different cell types using specific antibody markers...

The Littler flap has been widely used to repair large pulp defects of the thumb; however, several complications have occurred frequently. In order to reduce these issues, the modified Littler flap innervated by the dorsal branch of the proper digital nerve and the proper digital nerve from the ulnar aspect of the middle finger or the radial aspect of the ring finger were devised in 16 consecutive cases. At the donor site, the defect of the proper digital nerve was repaired with a nerve graft from the proximal portion of the ipsilateral dorsal branch of the proper digital nerve...

Tong Wu, Jiajia Xue, Haoxuan Li, Chunlei Zhu, Xiumei Mo, Younan Xia
Scaffolds functionalized with circular gradients of active proteins are attractive for tissue regeneration due to their enhanced capability to accelerate cell migration and/or promote neurite extension in a radial fashion. Here we report a general method for generating circular gradients of active proteins on scaffolds comprised of radially aligned nanofibers. In a typical process, the scaffold, with its central portion raised using a copper wire to take a cone shape, was placed in a container (upright or up-side-down), followed by dropwise addition of a bovine serum albumin (BSA) solution into the container...

The triceps brachii muscle occupies the posterior compartment of the arm in humans and has three heads. The lateral and medial heads originate from the humerus and the long head arises from the infraglenoid tubercle of the scapula. All heads form a common tendon that inserts onto the olecranon and the deep antebrachial fascia on each side of it. Each head receives its own motor branch, which all are thought to originate from the radial nerve. However, several studies reported that the motor branch of the long head of the triceps (LHT) arises from the axillary nerve or the posterior cord...

In this article, we report two cases in which recurrent adhesive hand neuropathy with allodynia were successfully treated with radial and ulnar artery adipofascial perforator flap coverage. Treatment of recurrent neuropathy, such as recurrent carpal tunnel syndrome and re-adhesion after neurolysis using free and pedicle flaps to cover the nerves, has been reported to show good results. However, for severe painful nerve disorders, such as complex regional pain syndrome, the efficacy of this treatment was unclear...

Superficial ulnar artery (SUA) is defined as arterial variation of an ulnar artery of high origin that lies superficially in the forearm. Because an SUA may be mistaken for a superficial vein, there is a risk of arterial damage. During routine dissection of the cadaver, we incidentally detected a case of unilateral SUA in the left arm. SUA arose from the axillary artery and descended superficial to the axillary artery and median nerve. At the wrist, the SUA crossed over palmaris longus (PL) tendon from the radial side to the ulnar side...

BACKGROUND: Intramedullary fixation for distal radius fractures is reported to be free of hardware irritation and less invasive than other fixation methods. Some specific complications associated with intramedullary fixation, such as radial nerve sensory neuritis, have been reported, but no study has focused on the complication rates of intramedullary fixation for distal radius fractures in the elderly population. Furthermore, no studies have analyzed common complications, such as carpal tunnel syndrome and flexor tenosynovitis including trigger finger, among patients with distal radius fractures treated by intramedullary fixation based on a comprehensive complication checklist...

BACKGROUND: There are several tendon transfers for reconstruction of irreparable subscapularis tears. The latissimus dorsi (LD) could be used because its direction and function are similar to those of the subscapularis. We performed LD transfers for irreparable subscapularis tears and evaluated clinical outcomes. METHODS: The study enrolled 24 consecutive patients who underwent LD transfers. Clinical and functional outcomes were evaluated using the Constant score, American Shoulder and Elbow Surgeons score, pain visual analog scale, and range of shoulder motion preoperatively and at last follow-up...
