Format:  45 minutes presentation, 15 minutes Q&A 

Webinar Description:
The retinacular system of the hand is a sophisticated network comprising the extensor and flexor retinacula, juncturae tendinum, sagittal bands, spiral oblique retinacular ligament, transverse retinacular ligament, triangular ligaments and palmar pulleys. These structures are intricately interconnected, playing a critical role in the biomechanics of digital motion. The significance of these components in regulating the precise forces required during flexion, extension, and opposition of the digits has been extensively documented by renowned authors such as Tubiana, Bunnell, Brand, and Kapandji. By controlling the excursion of the flexors, extensors, and intrinsic muscles, the retinacular system ensures the coordinated and effective function of the digits. Injuries, attenuation or adaptive shortening of any of these retinacular structures can disrupt the delicate kinematic balance, leading to various hand deformities, including swan neck and boutonniere/pseudo-boutonniere deformities. Accurate recognition of these pathologies, coupled with the application of specialized clinical tests, is essential for directing precise management strategies. Once diagnosed, treatment may involve relative motion splinting and standardized therapeutic measures aimed at enhancing joint motion, tendon excursion, and overall hand function. This presentation will feature illustrations, animations and clinical and cadaveric dissection videos to facilitate a comprehensive understanding of both normal and pathological digital mechanics. Integrating these media will serve as a foundation for evidence-based clinical management.


Learning Objectives:
Upon completion of this course, participants will:

  1. Gain a thorough understanding of the anatomy and function of the retinacular system
  2. Comprehend how these structures contribute to the smooth and synergistic movement of the phalanges and the excursion of tendons during digital flexion, extension and opposition
  3. Recognize the various deformities that may arise from dysfunctions within the retinacular system
  4. Acquire knowledge of the specific tests used to identify structural deficiencies
  5. Develop the ability to plan precise, evidence-based therapeutic interventions to maximize functional outcomes

Presenter(s)
Shrikant Chinchalkar, M.Th.O, B.Sc.OT, OTR, CHT

Shrikant worked as a senior hand therapist at the Roth-McFarlane Hand & Upper Limb Centre, St. Joseph’s Health Centre in London, Ontario, Canada for 26 years. He has over 50 years of clinical experience in treating upper extremity conditions, nearly 40 years of teaching, and 30 years of research experience. He designed and developed Hand Therapy programs at four major teaching centers in Canada including the Roth-McFarlane Hand & Upper Limb Centre in London, Ontario. In addition, he designed brachial plexus, peripheral nerve injury, elbow, wrist, and hand rehabilitation programs at these hospitals in Canada. In addition, he designed the most structured “Hand Therapy Fellowship program” for the training of therapists at this center. Shrikant worked as a guest lecturer at the University of Manitoba, University of Toronto, and Western University. He conducted many instructional courses on upper extremity rehabilitation in over 35 countries in the world and has won many awards for his presentations. He has over 300 presentations to his credit. He was awarded the Paul Brand Award of Excellence by the American Society of Hand Therapists (ASHT), Award of Leadership by the Canadian Association of Occupational Therapists (CAOT), Award of Excellence by the Sisters of St. Joseph’s Hospital, Best Educator by the Western University, Most Outstanding Prestigious Alumni by the Nagpur University in India, the Lifetime Membership Award by the Canadian Society of Hand Therapists (CSHT) and an award of Excellence in Teaching and Coaching by the administration of the St. Joseph’s Hospital. In 2017 the Hand Therapy fellowship program was named after him. It is now called the Chinchalkar Hand Therapy Fellowship Program at the Roth-McFarlane Hand & Upper Limb Center. In 2019 Shrikant received the Lifetime Achievement Award by the International Federation of Society of Hand Therapists (IFSHT) in Berlin. Also in 2019, he was chosen as an Honorary Advisor to the Asia Pacific Wrist Association in Seoul, Korea during their annual conference. Shrikant is also an “Honorary Advisor to the Society of Hand Therapy, India”. He served as a member of the Education Committee of IFSHT from 2019-2022. He currently serves on the Editorial Board of Hand Therapy Journal published by the British Society of Hand Therapy, an ancillary of the British Association of the Surgery of the Hand. Shrikant has authored six book chapters and has published more than 47 papers and 15 abstracts in numerous peer-reviewed journals related to Upper Extremity Surgery and Therapy.
