A small locking plate for reduction and fixation of proximal humeral fracture with severe medial instability. Late in life, the sagittal, coronal, and lambdoid sutures of the skull will begin to ossify and fuse, causing the suture line to gradually disappear. suture - skull term for a fibrous connective tissue joint. Crouzon syndrome is inherited in an autosomal dominant manner. This coronal suture may close (fuse) prematurely on one side (unicoronal) or both sides (bicoronal). Moreover, these data suggest a possible mechanism for syndromic craniosynostoses arising from FGFR2 gain-of-function mutations.
The plane may be in the center of the body and split it into two halves (mid-sagittal) or away from the midline and split it into unequal parts (para-sagittal).The anatomical term sagittal was coined by Gerard of Cremona. It then courses posterolaterally to blend with the epicranial aponeurosis at the level of the coronal suture of the skull. Coronal suture - unites the frontal bone with the parietal bones.
