anomaly

 [ah-nom´ah-le]
marked deviation from normal. adj., adj anom´alous.
Axenfeld's anomaly a developmental anomaly characterized by a circular opacity of the posterior peripheral cornea, and caused by an irregularly thickened, axially displaced Schwalbe's ring.
congenital anomaly (developmental anomaly) absence, deformity, or excess of body parts as the result of faulty development of the embryo.
Ebstein's anomaly see ebstein's anomaly.
May-Hegglin anomaly a rare dominantly inherited disorder of blood cell morphology, characterized by RNA-containing cytoplasmic inclusions (similar to Döhle bodies) in granulocytes, by large, poorly granulated platelets, and by thrombocytopenia.

hem·i·ver·te·bra

(hem'ē-ver'tĕ-bră),
A congenital defect of the vertebral column in which one side of a vertebra fails to develop completely due to failure of the chondrification center to form on this side. This produces scoliosis (lateral curvature of the vertebral column).

hemivertebra

Orthopedics A congenital vertebral body defect arising from a simple–ie, nondysplastic, nonmetabolic embryonal defect, in which the anterior half of a vertebral body is absent and adjacent vertebrae expand to fill the void, accompanied by preservation of interspaces. See Vertebra. Cf Butterfly vertebra.

hem·i·ver·te·bra

, pl. hemivertebrae (hem'ē-vĕr'tĕ-bră, -brē)
A congenital defect of a vertebra in which one side of a vertebra fails to develop completely.

The location of the hemivertebra is a significant factor in the progression of the deformity.
compared hemiepiphysiodesis or in situ fusion, instrumented fusion without hemivertebra excision, and instrumented hemivertebra excision.
On the other hand, hemivertebra excision is the only method that allows complete correction of the deformity by elimination of the pathology and yields predictable results.
The average amount of correction in the sagittal and coronal planes we achieved after hemivertebra resection with the posterior-only approach is around 90%.
Previous studies have reported that various complications may develop after hemivertebra resection including infection, bleeding, temporary or permanent neurologic injuries, failed instrumentation or recurrence of the deformity [2, 5, 8, 16, 20].
Complications such as hemorrhage, bleeding, infections, and recurrence of deformity associated with hemivertebra resection are rarely reported in the literature, but we have not encountered such a negative situation in our series (2-8).
These results demonstrate that hemivertebra resection by a posterior approach with segmental posterior transpedicular instrumentation is an effective and safe treatment options in children with congenital spine deformities.

En las radiografias se debe evaluar cuidadosamente la union craneocervical, con especial atencion en la articulacion axo-atlo-occipital para descartar la fusion atlooccipital; ademas se deben obtener radiografias laterales, antero posteriores y postero-anteriores del resto de la columna vertebral para : a) identificar o descartar anomalias vertebra-costales; b) observar el torax para descartar anormalidades cardiacas; c) identificar la posible fusion de las vertebras cervicales con las vertebras toraxicas; d) constatar o descartar la presencia de hemivertebras; e) detectar la espina bifida oculta, el disrafismo espinal, la fusion de costillas y las escoliosis.
En las radiografias dorsal y toraco- lumbar se pudieron observar: fusion de las costillas 1-2 y 5-6 del lado derecho, presencia de hemivertebras en T1, T2, T3 y T4, hemi-vertebra entre L2 y L3, fusion de L3 y L4, roto-escoliosis derecha, espina bifida en sacro, en la caja toraxica se observan multiples deformaciones costales que hacen el torax asimetrico pero sin causar desviacion de las estructuras mediastinales.
