What's the difference between flexion and retroflexion?

Flexion


Definition:

  • (n.) The act of flexing or bending; a turning.
  • (n.) A bending; a part bent; a fold.
  • (n.) Syntactical change of form of words, as by declension or conjugation; inflection.
  • (n.) The bending of a limb or joint; that motion of a joint which gives the distal member a continually decreasing angle with the axis of the proximal part; -- distinguished from extension.

  • (15) Although the entire cohort of neck patients, regardless of group assignment, improved significantly on all the outcome variables over the 6-week period, patients receiving intermittent traction performed significantly better than those assigned to the no traction group in terms of pain (P = 0.03), forward flexion (P = 0.01), right rotation (P = 0.004) and left rotation (P = 0.05).

  • (19) In severely impaired limbs, there was a marked shift in both the peak EMG angle and the angular domain of EMG activity for both biceps and triceps muscle groups, away from the normal elbow flexion-extension axis towards external humeral rotation and shoulder girdle elevation.
  • (20) On physical examination the patients complained of pain on both passive flexion and internal rotation of the hip, and when the thigh was pushed backwards at 90 degrees of flexion.

Retroflexion


Definition:

  • (n.) The act of reflexing; the state of being retroflexed. Cf. Retroversion.

Example Sentences:

  • (1) The most important differential diagnostic problems involve anencephaly with spinal retroflexion and the Klippel-Feil syndrome.
  • (2) Iniencephaly is a very rare malformation comprising a bone defect at the occiput, malformation of the cervical and thoracic vertebrae, spina bifida, and retroflexion of the head.
  • (3) It is associated with a defect in the occiput, alterations in the spinal column that are variable and retroflexion of the fetus.
  • (4) Moreover, the authors provided evidence that the area of the dural sac diminishes significantly in retroflexion, as compared with the neutral position in subjects with a normal spinal canal as well as in subjects with congenital stenosis of the spinal canal.
  • (5) Because of our good results, we make a plea for expectant management of retroflexion of the pregnant uterus.
  • (6) It is suggested that for precision the term "spinal retroflexion" should be used after duly prefixing it by an appropriate word (severe, moderate or mild) indicating the degree of retroflexion observed.
  • (7) The findings show that retroflexion in this variant of anencephaly can be classified into severe, moderate and mild forms.
  • (8) Retroflexion of the head with exaggerated cervicothoracic lordosis is always present, and CNS malformations in the form of anencephaly, spina bifida and encephalocele are often present.
  • (9) It is discussed that, though the anencephalies with severe or moderate degree of cervical retroflexion resemble iniencephaly in their features of spinal retroflexion, those having mild retroflexion are contrasted and should not be categorised with iniencephaly.
  • (10) The incidence of retroflexion in holoprosencephaly was apparently higher than that of ordinary subdural hygromas.
  • (11) A frequent feature is pain on retroflexion of the head.
