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...

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. ...

OBJECTIVES Acetabular retractors have been implicated in damage to the femoral and obturator nerves during total hip replacement. The aim of this study was to determine the anatomical relationship between retractor placement and these nerves. METHODS A posterior approach to the hip was carried out in six fresh cadaveric half pelves. Large Hohmann acetabular retractors were placed anteriorly, ...

The obturator foramen is large oval aperture in males or irregularly triangular aperture in females in the hipbone, situated anteroinferior to the acetabulum between the pubis and ischium. The dry bone under study is a male left sided hipbone. It contains the obturator groove through which the obturator nerve and vessels pass. During analysis of hipbones in the osteology laboratory of CSM ...

The obturator foramen is a large opening in the hip bone situated below and anterior to the acetabulum. The obturator foramen is enclosed by the obturator membrane, apart from the part above near the obturator groove, where the obturator vessels and nerve pass through. The present study reports multiple openings in the obturator foramen detected incidentally in a left hip bone specimen and disc...

BACKGROUND Pelvic masses are a common gynecologic problem, and majority of them are diagnosed as ovarian tumors finally. Sometimes, it is hard to distinguish the origin of these pelvic masses. The following case is a solitary neurofibroma arising from the right-side obturator nerve, which was impressed as a right-side ovarian tumor initially. We reported this case, and also performed a PRISMA-d...

BACKGROUND Intraoperative injury of the obturator nerve has rarely been reported in patients with gynecological malignancies undergoing extensive radical surgeries. Irreversible damage of this nerve causes thigh paresthesia and claudication. Intraoperative repair may be done by end-to-end anastomosis or grafting when achieving tension-free anastomosis is not possible. CASE PRESENTATION A 28-y...

Case A well nourished 43-year-old female presented with intestinal obstruction and a tender irreducible left femoral hernia. A viable loop of ileum was released from the hernia via a low inguinal approach and the small bowel proximal and distal were carefully examined. The femoral hernia was repaired and the patient made a slow but steady recovery, being discharged on the sixth postoperative da...

This review outlines the anatomy of the obturator nerve and the indications for obturator nerve block (ONB). Ultrasound-guided ONB techniques and unresolved issues regarding these procedures are also discussed. An ONB is performed to prevent thigh adductor jerk during transurethral resection of bladder tumor, provide analgesia for knee surgery, treat hip pain, and improve persistent hip adducto...
