Abstract : The anatomy of extensor tendons and juncturae tendinum (JT) is of interest to both anatomists and surgeons. Understanding the structure of the JTs and the interactions between the tendons of the fingers is of utmost importance in hand assessment, especially during the reconstructive procedures such as tendon transfers. During routine dissection of extensor tendons of dorsum of hand there was a filamentous band between the tendon of extensor pollicis longus and extensor indices in the first intermetacarpal space. This band was identified as Juncturae tendinae of Type 1. It was attached to the extensor tendons on either side of the first intermetacarpal space in a transverse direction. The presence of Juncturae tendinae in the first intermetacarpal space is a rare variation. This variation is important as it interferes with independent motion of thumb and index finger and also in tendon repairs.
