Dear Editor, Postoperative femoral neuropathy is an uncommon complication associated with pelvic/abdominal surgery. The main mechanism underlying this neuropathy is stretching and/or prolonged compression of the nerve.1,2 The nerve compression can be caused by the self-retaining retractors that are sometimes used during surgery directly constricting the nerve against the pelvic sidewall and ind...

Peripheral nerve injuries of the lower extremity (LE) are frequently encountered in orthopaedic practice. They can be traumatic or iatrogenic. Proper and timely diagnosis and treatment are the keys to optimizing outcomes. This paper reviews and discusses the basic anatomy and physiology of nerve injury and the current literature on the incidence, pathogenesis, diagnosis, management and outcomes...

A unique case of a body building champion with localised atrophy of the distal portion of the vastus lateralis muscle is reported; neurophysiological evaluation suggests a selective lesion of a distal branch of the vastus lateralis nerve (a motor branch of the femoral nerve). A necroscopic study in four cases was performed to better clarify the site and mechanism of nerve lesion. The data sugge...

BACKGROUND Recommendations regarding the technical aspects of nerve stimulator-assisted nerve localization are conflicting. The objectives of this study were to determine whether the placement of the cutaneous electrode affects nerve stimulation and to determine the duration and intensity of an electrical stimulus that allows nerve stimulation with minimal discomfort. METHODS Ten healthy volu...

INTRODUCTION Femoral nerve compression due to a cystic lesion around the hip joint is rare and only a few cases have been described in the literature. Among these, true ganglion cysts are even more rare. CASE PRESENTATION We report the case of a 57-year-old woman with femoral nerve compression caused by a true ganglion cyst of the hip joint. CONCLUSION A high index of suspicion is required ...

PURPOSE To evaluate the efficacy of a single shot "3-in-1" femoral nerve block for prosthetic hip surgery in association with general anaesthesia on post-operative analgesia. METHODS Forty patients, ASA 1 to 3, received sham block or "3-in-1" femoral nerve block, following Winnie's landmarks with a nerve stimulator, and 40 ml bupivacaine 0.5% with epinephrine were injected after induction of ...

Although the incidence of sciatic nerve palsy following total hip arthroplasty is low, this complication can cause devastating permanent nerve palsy. The authors experienced a case of sciatic nerve palsy caused by ruptured and contracted external rotator muscles following total hip arthroplasty in a patient suffering from osteonecrosis of the femoral head. We report this unusual case of sciatic...

Ultrasound-guided regional anesthesia can be challenging, especially for inexperienced physicians. The goal of the proposed methods is to create a system that can assist a user in performing ultrasound-guided femoral nerve blocks. The system indicates in which direction the user should move the ultrasound probe to investigate the region of interest and to reach the target site for needle insert...

BACKGROUND Positioning for subarachnoid block (SAB) in patients with femoral fracture is painful and may remain suboptimal requiring use of large doses of opioids. These patients generally being elderly with multiple comorbidities and frailty are likely to have many undesirable effects of opioids including respiratory depression and confusion. OBJECTIVE The objective was to compare the feasib...
