ObjectiveTo determine the intraoperative and early postoperative opioid requirement after ultrasound-guided sciatic and/or femoral nerve block or epidural anaesthesia in dogs undergoing tibial plateau levelling osteotomy (TPLO).Study designProspective, masked, pilot, randomized, clinical trial.AnimalsA total of 40 client-owned TPLO.MethodsEach dog was randomly assigned to group SF (combined blo...

background and objective: sciatic nerve transection is characterized by a rapid wave of motoneuron death associated with progressive synaptic lesions. the purpose of this study was to evaluate the long term synaptic changes. materials and methods: this basic study was carried out on paraffin- or resin-embedded tissue blocks for evaluation of synaptophysin and choline acetyl transaferase (chat) ...

BACKGROUND Blockade of the sciatic nerve is necessary for complete analgesia of the lower extremity using peripheral nerve blocks. We identified the sciatic nerve in relation to the ischial tuberosity in fresh cadaver dissections as well as in patients to compare sciatic nerve blockade using the conventional approach versus our experimental approach. Specifically, we tested the hypothesis that ...

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...

Sciatic nerve is the largest nerve in the body originating from the sacral plexus and it supplies the lower limb through its branches. It leaves the pelvic cavity and enters the gluteal region usually through the greater sciatic foramen below the piriformis. It divides into its terminal branches at various levels which determine the length of sciatic nerve. The present study is undertaken to me...

Neurology lays many claims to being one of the more precise and scientific branches of medicine but, nevertheless, there have been several neurological conditions almost mediaeval in their conceptions. One of these is a group included under the general heading of the neuritides-namely, sciatic and brachial neuritis and neuralgia. There is now a large body of evidence to show that the humoral, a...

Sciatic nerve entrapment can occur as post-operative complication of perineal hernia repair when sacrotuberous ligament is incorporated during hernia deficit closure. This results in sciatic sensory loss and paralysis of the hind leg. This study investigated the spatial relationship of sciatic nerve and sacrotuberous ligament and their surface topographic projection of 68 cadavers (29 Beagles a...

In discussing this rare phenomenon, the author considers it result of compression intrapelvic segment sciatic nerve by a large fetal head in narrow pelvis or traumatization with forceps.

Total hip arthroplasty (THA) in patients with high hip dislocation is challenging and technically demanding. Nerve injury is a problem associated with leg lengthening after THA. The purpose of this study was to identify the risk factors for sciatic nerve injury after THA in patients with high hip dislocation. Thirty-seven patients (41 THAs) with Crowe type IV hips were consecutively treated. Th...
