Symbrachydactyly Of Hand: Report Of A Case With Review Of Li
The symbrachydactyly is one of the relatively rare congenital malformations of the hand and is literally defined as a combination of brachydactyly (short fingers) with syndactyly.The brachydactyly usually involves middle phalanges of the digits (brachymesodactylous) while the syndactyly is predominantly cutaneous. They often manifest sporadically though familial occurrence is not uncommon. The exact cause of Symbrachydactyly is unknown but some insult to the mesenchyme during early gestational period is considered to be the causative factor. The condition usually manifests unilaterally and based on morphological features, classified ranging from simple shortness of middle phalanges to complete absence of the digital rays. The management depends upon the severity of the manifestation and the options range from reassurance to complex surgical reconstructions to improve the digital length for enhanced mechanical advantage and prehension.
Case Report
A 6 year old male child presented to us with congenitally shortened left hand with fused index, middle and ring fingers.
The other hand and both the feet were normal. There were no associated cardiovascular, gastrointestinal or genitourinary system anomalies.

On examination, the child was having a hypoplasia of the left hand and was relatively small by 30% of the uninvolved hand. The index, middle and ring fingers of the involved hand were short with complete, simple syndactyly...
