Arthroscopic techniques are an emerging technology to deal with glenoid bone defects in patients with anterior shoulder instability, and improvements are being made to safely minimize the risk of injury to the anterior neurovascular structures including the axillary nerve. Arthroscopic glenoid reconstruction is a technically demanding procedure, but it does have promising short-term outcomes. I truly like the concept of anterior (and also posterior) bone grafting for defects of the glenoid, including the arthroscopic Latarjet.

The popliteal nerve plexus contributes to afferent knee-pain conduction. It is mainly formed by genicular branches from the posterior obturator and the tibial nerves, innervating the intra-articular and posterior knee region. A subinguinal obturator nerve block alleviates pain after total knee arthroplasty.

Functional recovery after a recurrent laryngeal nerve or facial nerve injury may be impaired due to aberrant reinnervation. Previous work in a rat peripheral nerve injury model found vincristine to be a potent inhibitor of reinnervation, and it has since been used to effectively block neural regeneration in other animal models. However, vincristine's narrow therapeutic index may limit its utility; therefore, another microtubule inhibitor, paclitaxel, which has a higher therapeutic index, was tested.

This prospective randomized trial compared ultrasound-guided single-injection (SI) and triple-injection (TI) subparaneural popliteal sciatic nerve block. We hypothesized that multiple injections are not required when local anesthetic (LA) is deposited under the paraneurium because the latter entraps LA molecules, ensuring circumferential spread around the nerve. Therefore, in addition to comparable success rates, we also expected similar total anesthesia-related times (sum of performance and onset times) and designed this study as an equivalency trial.

Sciatic Nerve (SN) is the nerve of the posterior compartment of thigh formed in the pelvis from the ventral rami of the L4 to S3 spinal nerves. It leaves the pelvis via the greater sciatic foramen below piriformis and divides into Common Peroneal Nerve (CPN) and Tibial Nerve (TN) at the level of the upper angle of the popliteal fossa. Higher division of the sciatic nerve is the most common variation where the TN and CPN may leave the pelvis through different routes.

Scar ulcers that spread over the Achilles tendon and posterior heel disturb patients by causing pain, impeding hygiene, and creating difficulty in finding appropriate shoe wear. As this region undergoes pressure, effective reconstruction is based on the flap use. The most popular flaps currently used are distally based sural fasciocutaneous flap, calcaneal artery skin flap, and free flaps.

Ultrasound (US) guidance, in some instances, can increase the success rate and reduce the onset and procedure times for peripheral nerve blockade compared with traditional nerve localization techniques. The presumptive mechanism for these benefits is the ability to accurately inject local anesthetic circumferentially around the target nerve. We aimed to determine whether ensuring circumferential spread of local anesthetic is advantageous for US-guided popliteal sciatic nerve block.

The sciatic nerve is the largest nerve, with a long course in the inferior extremity. Its division into the tibial and common peroneal nerves can occur at any level from the sacral plexus to the inferior part of the popliteal space. These anatomical variations may contribute to clinical conditions such as piriformis syndrome, sciatica and coccygodynia.

Plantar fasciitis (PF) is a common clinical condition that usually resolves with non-operative treatments. Extracorporeal shock wave therapy (ESWT) has been used in the treatment of chronic PF not responding to other conservative measures; however, ESWT devices are expensive and available for daily practice in only few centers (In developing countries). A pneumatic lithotripter is a cheap and readily available device which uses pneumatic shock application for the intracorporeal lithotripsy.

PURPOSE OF THE STUDY Regional anaesthesia for the lower extremity distal to the ankle joint, knows as anaesthetic ankle block or foot block, involves a series of injections of local anaesthetic to block the peripheral nerves that supply innervation to the foot. Since the tibial nerve block is not always effective, the aim of this study was to design a modified technique of anaesthetic application. MATERIAL The study was carried out on 30 human cadavers provided by the Institute of Anatomy, 1st Faculty of Medicine, Charles University in Prague, and included data on a total of 60 lower extremities.
