| disputed neurogenic thoracic outlet syndrome | <syndrome> A highly controversial disorder in which the brachial plexus is reputedly repressed at one or more sites along its course, particularly within the interscalene triangle, and between the normal first thoracic rib and some other structures; frequently attributed to trauma (particularly automobile accidents, and most often diagnosed in young to middle-aged women; no characteristic clinical presentation, although forequarter pain is characteristic; no definite objective findings are present, and no undisputed ancillary diagnostic studies are available.

| true neurogenic thoracic outlet syndrome | <syndrome> Very chronic axon loss brachial plexopathy, caused by compromise of the lower trunk fibres by a congenital band extending from a rudimentary cervical rib to the first thoracic rib; rare disorder, found mostly in young to middle-aged women, that presents with unilateral hand wasting and weakness, particularly involving the lateral thenar eminence; sometimes accompanied by intermittent discomfort along the medial forearm and hand. Synonym: cervical rib and band syndrome, classic cervical rib syndrome. (05 Mar 2000) |

Synonym: anteroposterior diameter of the pelvic inlet, conjugata vera, conjugate axis, conjugate diameter of pelvic inlet, diameter mediana, internal conjugate, true conjugate. (05 Mar 2000) |
| parietal pelvic fascia | Including the obturator fascia, covers the muscles that pass from the interior of the pelvis to the thigh. Synonym: fascia pelvis parietalis. (05 Mar 2000) |
