The hand and wrist are formed during the 8th week of gestation. This process consists of various steps and failure in any one or more of these steps may cause congenital or birth defects. The deformities may be major (absence of a bone) or minor (disproportion of a finger).
Neuromuscular hand conditions refer to disorders of the hands that occur due to an injury or compression of the nerves in the hands or arms that impact the muscles. Neuromuscular hand conditions affect the normal functioning of one or both hands beginning with muscle weakness, pain, numbness, improper coordination, and may lead to paralysis if not treated quickly.
