Here it enters the thigh, through the obturator canal, and divides into an anterior and a posterior branch, which are separated at first by some of the fibers of the obturator externus, and lower down by the adductor brevis. [2] An accessory obturator nerve may be present in approximately 8% to 29% of the general population. [3]
A palatal obturator is a prosthesis that totally occludes an opening such as an oronasal fistula (in the roof of the mouth). They are similar to dental retainers , but without the front wire. Palatal obturators are typically short-term prosthetics used to close defects of the hard/soft palate that may affect speech production or cause nasal ...
Obturator hernia The Hannington-Kiff sign is a clinical sign in which there is an absent adductor reflex in the thigh in the presence of a positive patellar reflex . It occurs in patients with an obturator hernia , due to compression of the obturator nerve .
Disposable trocars Laparoscopic instruments for insertion through trocars. A trocar (or trochar) is a medical or veterinary device used in minimally invasive surgery.Trocars are typically made up of an awl (which may be metal or plastic with a pointed or tapered tip), a cannula (essentially a rigid hollow tube) and often a seal.
Part of a trocar device A device used as a guide during tracheostomy tube insertion Palatal obturator , a dental prosthesis used to seal an opening in the palate, i.e. cleft palate
The obturator nerve is the primary nerve supplying this compartment. The obturator artery is the blood supply to the medial thigh. The muscles in the compartment are: gracilis; adductor longus; adductor brevis; adductor magnus; The obturator externus muscle is sometimes considered part of this group, [1] [2] [3] and sometimes excluded. [4]
This fossa is the point of insertion of four muscles. Moving from the inferior-most to the superior-most, they are: the tendon of the obturator externus muscle, the obturator internus, the superior gemellus and inferior gemellus. The width and depth of the trochanteric fossa varies taxonomically. [1] [2] [3]
The nerve to obturator internus (also known as the obturator internus nerve [citation needed]) is a mixed (sensory and motor) [1] nerve providing motor innervation to the obturator internus muscle and gemellus superior muscle, [2] [1] and sensory innervation to the hip joint. [1] It is a branch of the sacral plexus. It is one of the group of ...
