Sciatic nerve is the thickest nerve of the body which is formed by ventral branches of L4, L5, S1, S2 and S3 of spinal nerves as a part of sacral plexus in pelvis. It leaves the pelvis via the greater sciatic foramen below piriformis muscle and descends between the greater trochanter and ischial tuberosity, along the back of the thigh and dividing into the tibial and common peroneal (fibular) n...
background: effects of platelet-derived growth factor b (pdgf-b) on peripheral nerve regeneration was studied using a rat sciatic nerve transection model. materials and methods: forty‑five male, white wistar rats were divided into three experimental groups (n = 15), randomly: normal control group (nc), silicon group (sil), and pdgf‑b treated group (sil/pdgf). in nc group, left sciatic nerve was...
The sciatic nerve is a largest single nerve of the lumbosacral nervous plexus. This nerve innervates all muscles of the leg and foot as well as the flexor muscles of the knee joint. Many variations in the direction and relations of sciatic nerve were described. The current case report presented a thick septum situated posterior to the sciatic nerve and its branches spread throughout the back of...
Purpose: There are extensive evidences that show axonal processes of the nervous system (peripheral and/or central) may be degenerated after nerve injuries. Axonal regeneration is relation to various factors. In this investigation we decided to evaluate the effects of nerve regeneration age-dependent on injured rat sciatic nerv. Materials and Methods: For this study, the right sciatic nerve of...
regarding the importance of sciatic nerve distribution in replacement of anal sphincter and sciatic nerve block we decided to study this matter for the first time in iran. in this way 100 cadavers (88% male and 12% female) were dissected and studied by loop microscope. the results shows that primarily, according to the first branch derived from sciatic; there would be 4 main groups. if this sam...
Introduction: Repair of peripheral nerve injuries is an intensive area of challenge and research in modern reconstructive microsurgery. Intensive research is being carried out to develop effective alternatives to the standard nerve autografting, avoiding its drawbacks. The aim of the study was to evaluate the effectiveness of a newly designed mechanical device for the reconstruction of the...
Objective(s): We investigated the histopathological effects of metamizole sodium (MS) on the sciatic nerve. Materials and Methods: This study was performed using 48 adult male Wistar albino rats. Ten groups were constituted with 6 rats in each group. MS injection into the sciatic nerve (group 1), MS injection into the muscle [group 3 (50 mg/kg, 0.4 ml) and group 5 (50 mg/kg, 0.8 ml)], MS injec...
Introduction: Peripheral nerve damage is a clinical problem that causes sensory and motor disabilities. Sesamol is an antioxidant that can be effective in repairing various organs. The aim of this study was to evaluate the effect of different doses of sesamol on inflammation and pain in the damaged rat sciatic nerve. Materials and Methods: In this study, 35 adult male Wistar rats were used. The...
objective: to determine the effects of local administration of platelet rich plasma (prp) on peripheral nerve regeneration in rat sciatic nerve transection model. methods: forty-five male white wistar rats were randomized into three experimental groups (n = 15): normal control group (nc), silicon group (sil), prp treated group (sil/prp). in nc group left sciatic nerve was exposed through a glut...
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...
