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: To investigate the efficacy of a type I collagen-derived artificial tubular implant on sciatic nerve regeneration. Materials and Methods: Sprague-Dawley rat sciatic nerve injury model was built by cutting a 5.0 mm defect on the sciatic nerve of the right thigh. Rats with sciatic nerve injury were treated with type I collagen-derived artificial tubular implants (Group A), autologous c...

OBJECTIVE To evaluate the anatomic topographic relation between the sciatic nerve in relation to the piriform muscle and the posterior portal for the establishment of hip arthroscopy. METHODS We dissected 40 hips of 20 corpses of adult Brazilians, 17 male and three female, six black, six brown and eight white. We studied the anatomical relationship between the sciatic nerve and the piriform m...

OBJECTIVES 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 injectio...

OBJECTIVE(S) Crocin is a constituent of saffron and has many biological functions. The present study aimed to investigate the effects of intraperitoneal (IP) injection of crocin on sciatic nerve regeneration in male Wistar rats. MATERIALS AND METHODS Fifty-four rats were divided into 9 groups: groups 1-4 (intact + normal saline and intact + crocin at doses of 5, 20 and 80 mg/kg, respectively)...

abstract traumatic hip dislocations are common in high-energy motor vehicle accidents. we present a case of a 43-year old man who sustained posterior hip dislocation with posterior wall acetabular fracture and ipsilateral intertrochantric fracture following a motorcycle accident. urgent open reduction and internal fixation of the hip fracture-dislocation and fixation of intertrochantric fractur...

objective: because of the necessity of more effective treatments for the nervous system injuries and considering the role of survivin in cellular proliferation and apoptotic cell death, we have monitored survivin gene expression changes during the course of regeneration in injured sciatic nerves and also l4-l6 segments of spinal cord. materials and methods: we used adult male nmri mice as a mo...

With great interest, we read the article by Prakash et al, entitled “Sciatic nerve division: a cadaver study in the Indian population and review of the literature”.(1) A total of 86 inferior extremities were dissected in order to expose the sciatic nerve, including its division into the tibial and common peroneal nerves. First, we would like to commend the authors for emphasising the issue of s...

objective: the aim of present study was to evaluate the effects of oral administration of gallic acid (ga) for 21 days alone and in combination with exercise on nerve conduction velocity and sensory and motor functions in rats with sciatic nerve crush. materials and methods: seventy adult male wistar rats (250-300 g) were divided randomly into 7 groups with 10 in each: 1) control (cont), 2) cru...

THE problem of sciatic pain is a complex one. Justification for this paper lies in the belief that it is insufficiently understood and that on the whole there is a widespread laxity in accurate diagnosis, with the inevitable corollary that treatment may be inappropriate or inadequate. There is no need to emphasise the frequency of such pain. Most cases are treated by the general practitioner, b...
