despite promising results observed using silicone rubber chamber, no previous comprehensive work was performed on behavior of the conduit. present study aimed at further functional, histomorphometrical and immunohistochemical assessment of nerve regeneration in the same animal along a 10-mm rat sciatic nerve gap. fifty- four male wistar rats were divided into three experimental groups (n = 18),...

BACKGROUND AND OBJECTIVES Unilateral spinal anesthesia has advantages when used in outpatient basis. The objective of the present study was to compare unilateral spinal anesthesia with combined sciatic-femoral nerve block in unilateral orthopedic surgeries in outpatients. METHODS Sixty patients were randomly divided into two groups of 30 patients to receive 6 mg of hyperbaric or hypobaric bup...

OBJECTIVE The aim of this study is to compare the effects of parasacral and posterior Winnie approaches when combined with the inguinal paravascular approach for lumbar plexus block. METHODS After the approval of the Ethics Committee, 40 patients scheduled to undergo arthroscopic knee surgery were enrolled. The patients were randomly assigned into two groups in a double-blind manner to perfor...

OBJECTIVES The efficacy of combined lumbar plexus-sciatic nerve blocks was compared to epidural anesthesia in patients undergoing total knee surgery. PATIENTS AND METHODS The study included 80 American Society of Anesthesiologists (ASA) Physical Status I-III patients (age range 18 to 65) undergoing knee surgery. The patients were randomly divided into one of two groups. Epidural anesthesia wa...

Objective- The objective was to assess local effect of brain derived neurotrophic factor (BDNF) on functional recovery of peripheral nerve in rat sciatic nerve transection model. Design- Experimental study. Animals- Sixty male healthy white Wistar rats Procedures- The animalswere randomized into four experimental groups of 15 animals each: In sham-operated group (SHAM), sciatic nerve was exp...

INTRODUCTION 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. METHODS This study was perf...

Objective(s):  The aim of this study was to evaluate the final outcome of nerve regeneration across the eggsell membrane (ESM) tube conduit in comparison with autograft. Materials and Methods: Thirty adult male rats (250-300 g) were randomized into (1) ESM conduit, (2) autograft, and (3) sham surgery groups. The eggs submerged in 5% acetic acid. The decalcifying membranes were cut into four pie...
