W e congratulate Kwofie et al 1 on their thorough study on the motor effects after adductor canal block (ACB). The authors found no motor weakness after ACB in healthy volunteers using a relatively high volume of local anesthetic. The injection was made at a point considered distal to the motor supply to the quad-riceps femoris muscle. However, the motor branch to the vastus medialis muscle con...

RATIONALE Although lower-extremity surgeries are mainly performed under general or central neuraxial anesthesia, ultrasound-guided peripheral nerve block (PNB) can be a good alternative, especially for patients who require continuous anticoagulation treatment and present with poor cardiovascular conditions. PATIENTS CONCERNS The patient required continuous anticoagulation treatment due to the...

•Intraoperative injury of the obturator nerve is not an infrequent complication of gynecological surgeries.•This injury can occur in association with pelvic lymphadenectomy for uterine or cervical cancer.•This manuscript demonstrates an alternative technique for the obturator nerve repair, when primary end to end anastomosis is not possible.

UNLABELLED Chronic perineal pain is often a difficult condition to manage. Current treatments include pudendal nerve injections and pudendal nerve release surgery. The obturator internus muscle has a close relationship to the pudendal nerve and might be a potential target for therapeutic intervention. PERSPECTIVE A case is presented of refractory perineal pain that was successfully treated by...

Single spinal anesthesia in transurethral resection of bladder tumor (TURBT) has been reported to be unable to prevent obturator nerve stimulation and adductor muscle contraction, which can cause complications like bladder perforation. The present study aimed to compare the effectiveness of the classic and inguinal approaches for obturator nerve block (ONB ). Seventy patients with cancers of th...

Management of pain from skeletal metastases is notoriously difficult. Case reports and case series have described radiofrequency ablation of the obturator nerve branches to the femoral head for treatment of intractable hip pain. Ablation of the obturator branches to the femoral head is technically difficult because of bony and vascular anatomy, including close proximity of the femoral vessels. ...

BACKGROUND This study aimed to estimate the minimum effective anaesthetic concentrations of lidocaine required to block the femoral nerve under ultrasound (US) guidance in 90% (MEAC90) of patients. METHODS A minimum of 45 patients who had undergone knee arthroscopy were included in this observational study. All the patients received US-guided sciatic, obturator, and femoral nerve blocks. The ...
