Category: Anatomy


Introduction: Juncturae tendinae (JT) (Intertendinous connections) are oblique intertendinous fiber bands between extensor tendons in the Inter Metacarpal Space (IMCS).These juncturae tendinae are clinically important since the finger extension can be preserved when the extensor digitorum longus is lacerated proximal to the juncturae tendinae.

Aim & Objectives : To study the morphology of juncturae tendinae of extensor tendons of hand.

Materials & Method : The present study was carried out in the Department of Anatomy, Aarupadai Veedu Medical College, Pondicherry. Fifty South Indian cadavers with intact upper limbs aged between 30 and 70 years were used for this study . The extensor tendons to each finger were exposed identified, cleaned and the gross appearance, shape, location and distribution of the juncturae tendinae were studied.

Results: In the present study Juncturae Tendinae(JT) were absent in 18 hands (18%). Juncturae tendinae (JT) was absent in the 1st IMCS of all hands. In the remaining spaces Type 1 was absent in the 4th IMCS of all hands and Type 3 r and y pattern were absent in 2nd IMCS of all hands.

Conclusion: A knowledge in complex anatomy of intertendinous connections (Juncture Tendinae) between the extensor tendons is essential for hand assessment, repair, and reconstruction during injury. The results of the present study confirm the findings of previous studies on intertendinous connections.
