“…10 The obturator nerve division is known for its variations with respect to its topography in the obturator canal. 11 Berhanu et al 12 observed intrapelvic division of obturator nerve in 23.9% cases, in the obturator canal in 44.8% cases and infrapelvic in 31.3% cases. In the present study, no extrapelvic divisions were observed (0%).…”

“…There was no division of the obturator nerve in 20% of samples. According to Tshabalala et al 11 from the South African population, intrapelvic branching was observed in 2% of cases, and the majority were branching in the obturator canal (93%). Extrapelvic branching was observed in 5% of cases.…”

“…Anesthesia may be incomplete if there are variations in branching pattern. 11 This study was aimed at helping clinicians, but its limitations, such as individual branches to the muscles it supplies, were not explored. A gender-based comparison of morphometric data was not performed.…”

Background The goal of this cadaveric cross sectional study was to analyse the branching pattern of the obturator nerve morphologically and to determine its dimensions in embalmed cadavers. Methods In this cross sectional study, we examined 50 embalmed adult cadaveric lower limbs. Sex was not taken into consideration in the analysis; however, a side-based comparison was performed. The measurements were performed using a digital Vernier caliper. Results The branching of obturator nerve was observed at the pelvic cavity in 28 specimens (56%) and inside the obturator canal in 12 specimens (24%). The division of obturator nerve wasn’t observed in 10 specimens (20%). The length, width and thickness of the trunk of obturator nerve was 108.26 ± 9.53 mm, 2.84 ± 0.88 mm and 1.11 ± 0.35 mm. The width and thickness of the anterior and posterior divisions of obturator nerve measured 2.19 ± 0.82 mm, 0.9 ± 0.1 mm, 0.99 ± 0.6 mm and 0.71 ± 0.26 mm. The topography of branching of obturator nerve from the superior and inferior border of the obturator foramen was located at 1.48 ± 0.58 mm and 3.07 ± 1.1 mm away. The length of anterior division of the obturator nerve measured 110.88 ± 12.02 mm over the right side and 107.13 ± 7.81 mm over the left side. The width of the main trunk of obturator nerve was 2.87 ± 0.64 mm over the right side and 2.82 ± 0.64 mm over the left side. Conclusions We believe that morphometric data of the obturator nerve will be enlightening to the operating surgeon during procedures such as obturator nerve block, nerve transplantation, and obturator nerve repair. The dimensions of the obturator nerve observed in the present study can be utilized as a morphological database for our sample population.

“…This information can find its application in clinical and educational practice. The high variability of the branches and course of the nerve is particularly relevant in orthopaedics for the treatment of hip pain [9], knee pain [3] and inguinal pain [10] The variability of the obturator nerve is also of importance in performing obturator nerve blocks, e.g. in anaesthesiology when carrying out anaesthesia of the knee joint [1] and in neurology when treating spasticity of the thigh muscles supplied by the obturator nerve [4].…”

“…The obturator nerve is characterized by a very high degree of variability in both its origin, course, and branches. The wide variety of branches and course of the obturator nerve is clinically important for, among others, orthopedists, surgeons, and anesthesiologists during procedures requiring nerve block [1] and treatment of pain in innervated joints [3] or paralysis of innervated muscles [4]. Advancing knowledge of obturator nerve morphology improves the clinical efficacy of locally performed medical procedures.…”

An undescribed junction between the obturator nerve and the saphenous nerve was identified during an autopsy. A case report was conducted using routine dissection techniques, and the material was accessed through a local informed donation program. The case report presented here has an important clinical implications for surgeons operating in the area. An understanding of the anatomy of the obturator nerve and knowledge of its variations is essential for surgical procedures, pain management, radiological diagnosis, and education.
