  Glossary search - adduction.   (Site not responding. Last check: 2007-08-06)
Adduction means to take or lead towards (originally from the latin adducere) so that adduction moves one part of the body closer to another.
In the case of the lower limb, adduction movements of the hip move the whole limb towards the mid-line of the body; thus, adducting both hip joints would bring the legs together.
Powerful adduction of the hip joint allows the legs to grip and is important in activities like climbing or riding a horse.

The higher the adduction moment, the greater the load on the medial plateau relative to that of the lateral plateau, and the higher the bone mineral content in the proximal tibia under the medial plateau (B in Figure 1) as compared to that under the lateral plateau (24).
It has also been shown that although the preoperative adduction moment is not correlated with the mechanical axis, the postoperative adduction is correlated with the postoperative mechanical axis, and the change in the adduction moment is correlated with the change in the mechanical axis (25).
The external knee adduction moment was increased by 10 percent and the external knee flexion moment by 20 percent.

 Testosterone Nation - Construction by Adduction
Adduction refers to the movement of a limb toward the midline of the body in the frontal plane (also known as the coronal or lateral plane).
While adduction is the primary function of each, the amount of hip flexion present determines whether or not some of the adductors work on the femur as medial or lateral rotators and extensors or flexors (2).
In those eight players, average preseason hip adduction strength was 18% lower than that of the players that did not experience a groin injury.

Adduction is performed by means of the logical relations described by hypothetical and disjunctive propositions.

 U of MI/Muscles in Action
A movement of a body part away from the midline, either of the body as a whole or that of the hand or foot, is termed abduction (L., to carry away).
In addition, movement of certain of the metacarpals (or metatarsals) occurs at their joint with carpal bones of the wrist (or tarsals of the foot).
The actions of abduction and adduction were previously described with regard to movements relating to the body as a whole.

He initially believed that the simulated inferior oblique palsy was due to an innervational disturbance to this muscle, with secondary contracture of the anterior sheath of the superior oblique tendon.

Therefore, a new adduction procedure (adduction arytenopexy) was devised to affix the arytenoid on the cricoid facet in a more optimal position for glottal sound production.
The arytenoid is rocked internally on the cricoid facet, and suture tension is adjusted appropriately to simulate normal cricoarytenoid adduction.
In the first study, the adduction arytenopexy was compared with the classic arytenoid adduction in 10 fresh cadaver larynges.

 eMedicine - Duane Syndrome : Article by Arun Verma, MD   (Site not responding. Last check: 2007-08-06)
In neuropathologic terms, the cause of DS is an absent sixth-nerve nucleus and innervation of the lateral rectus by a branch of the inferior division of the third nerve.
Therefore, the generally accepted concept was that the cause of abduction deficiency was fibrosis of the lateral rectus muscle and that the limitation of adduction was caused by a false posterior insertion of the medial rectus muscle or by adhesions between the medial rectus muscle and the orbital wall.
The upshoot in adduction that often is seen in DS bears some resemblance to inferior oblique overaction, but inferior oblique weakening procedures usually are ineffectual in correcting the problem.

Note the under-elevation in adduction of the right eye, which is worse in attempted gaze to the patient's upper left.
The cause of vertical binocular diplopia in this patient was a ethmoidal sinus mucocele pressing on the globe resulting in effacement of the superior oblique tendon with anterolateral displacement of the trochlea thus causing a limitation to elevation in adduction classically known as Brown Syndrome.
Following endoscopic removal of the mass the patient was relieved of diplopia and ugze ability in adduction was improved, but moderately limited.

Medialization laryngoplasty reduces the glottal gap in the anterior vocal fold and therefore is often combined with arytenoid adduction to also minimize the posterior glottal gap.

The purpose of this study is to directly compare the acoustic and aerodynamic effects of medialization laryngoplasty and arytenoid adduction versus adduction arytenopexy in an excised, human larynx model.
