Abstract

The Retinacular system of the hand consists of extensor and flexor retinaculum, juncture tendinum, sagittal bands, spiral oblique retinacular ligament, transverse retinacular ligament, triangular ligaments, and the palmar pulleys. These structures have an intricate relationship with each other. The importance of these structures on the biomechanics of the digital motion is well described by various authors including: Tubiana, Bunnell, Brand, and Kapandji. These structures transmit precise forces during flexion, extension and opposition of the digits, by regulating excursion of flexors, extensors and the intrinsics for digital function.  Extensor or the flexor tendon injuries, attenuation or adaptive shortening of any of the retinacular structures disrupt the kinematic chain equilibrium and lead to various hand deformities such as swan neck and boutonniere/pseudo-boutonniere. Recognition of pathologies, and conducting special clinical tests directs precise management of the various clinical conditions. Once diagnosed, treatment may consist of relative motion splinting and standard therapeutic measures to increase joint motion, tendon excursion, and function.
The presentation includes illustrations, animations clinical and the cadaveric dissection videos to simplify understanding of the normal and disturbed digital mechanics. The use of the above-mentioned media is to contribute to the evidence of clinical management. 

 Course Objectives
Upon completion of the webinar the participants will have:

1. A thorough knowledge of the retinacular system anatomy and it’s function
2. An understanding of how these structures influence smooth and synergistic motion of the phalanges and excursion of the tendons during flexion, extension and opposition of the digits
3. An understanding of various deformities that are likely to develop due to malfunctioning of the retinacular system
4.  An in-depth knowledge of which tests are performed to identify structural deficiencies
5. An ability to plan an evidence based precise therapeutic intervention to maximize the functional outcome.
