UNLABELLED In 1973, Winnie et al. introduced the inguinal paravascular three-in-one block, which allegedly provides anesthesia of three nerves--the femoral, lateral cutaneous femoral, and obturator nerves--with a single injection. This concept was undisputed until the success of the obturator nerve block was reassessed by using evidence of adductor weakness rather than cutaneous sensory blockad...

Both obturator and sciatic nerve block in combination with femoral nerve block (FNB) have been suggested to be useful in relieving pain after total knee arthroplasty (TKA), compared with FNB alone. We compared their efficacy in this retrospective study. For six consecutive months, patients undergoing unilateral TKA under general anesthesia with continuous FNB plus obturator nerve block (n = 8) ...

BACKGROUND AND OBJECTIVES The participation of the obturator nerve in 3:1 blockades is controversial. Superficial surgical interventions in the medial face of the thigh strike femoral and obturator nerves dermatomes with imprecise, overlapped or even absent limits. The correlation between clinical outcome and other diagnostic methods may be conclusive about the involvement of the obturator nerv...

BACKGROUND Obturator nerve block plays an additive role on the quality of analgesia for knee surgery. Since the use of dual guidance increases the success rate of nerve blocks, we investigated the feasibility of performing anterior cruciate ligament reconstruction under dual-guided blockade of obturator with femoral and sciatic nerves. Furthermore, we propose a novel method for the assessment o...

Obturator nerve block has been commonly used for pain management to prevent involuntary reflex of the adductor thigh muscles. One of several options for this block is chemical neurolysis. Neurolysis is done with chemical agents. Chemical agents used in the neurolysis of the obturator nerve have been alcohol, phenol, and botulinum toxin. In the current case, a patient with spasticity of the addu...

INTRODUCTION Idiopathic obturator neuralgia is a rare chronic pain condition. It consists of pain radiating from the obturator nerve territory to the inner thigh. However, the symptomatic obturator neuralgia is commonly caused by the obturator canal bowel hernia that causes painful commpressive neuropathy in more than 85% of the cases. CASE REPORT A 61-year-old female who underwent right femo...

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...
