The Human Hand: A Study of Anatomy and the Anatomical Relationships of the Intrinsic and Extrinsic Mechanisms in Reference to Zone 1 and II Flexor Tendon Injuries

Saturday, November 4th 2023

Location: Saginaw, MI

Delivery format: LIVE (in-person)


Mike Cricchio, MBA, OT/L, CHT

8 Continuing Education Credits.  Occupational Therapy continuing education credit only.

Registration Fee: $285.00

Level: Intermediate

This course is ideal for therapists who are preparing for the CHT Exam or who are pursuing a study of the upper extremity. The course will advance understanding of a intrinsic anatomy, pathology and flexor tendon management while expanding your clinical reasoning via case study analysis regardless of your level of experience.

3-1 Kinesthetic Teaching Model


Course Description: 

Participants will actively learn and participate in the detailed study of the intrinsic anatomy and anatomical relationships of the hand via didactic presentation, discussion, drawing labs and case presentation. Presentation and lab formats will foster an environment of collaborative interaction that promotes independent and group problem-solving and skill development.

Learning Outcomes Assessment Methods:

The learner will be provided a verbal and written list of drawing interventions to be performed throughout the conference. The learner will demonstrate the ability to recognize and treatment make judgments based on anatomy and evidence-based interventions by verbally reciting, drawing and recording to group partners using the below 3-1 Kinesthetic Teaching Model. The learner will then put anatomical and pathological concepts together to create new and novel constructs of learning.

3-1 Kinesthetic Teaching Model:

This conference will provide the learner with the opportunity to participate in an indelible learning experience. One drawer, one narrator, one videographer, one small group. Three distinct and effective methods of adult learning, using a single model of The Dell Hand.

The Dell Hand is an individually and professionally sculpted translucent model of the hand. The model provides an artistic rendering of the human hand in which the student can visually appreciate the natural contours of the hand while gaining insight into the osseous and intrinsic anatomy of the hand.

The translucent exterior provides a smooth surface in which the student can illustrate anatomic structures with dry erase markers. All markings easily wipe completely clean. The Dell Hand models, Zenzoi dry erase markers and cleaning kits will be provided by The Teton Hand and Upper Extremity Conference Series for use during the conference.

During the drawing segments of the conference, all attendees will be divided into small groups of three therapists and one Dell Hand (3 to 1 Model).

All participants are to come with a charged cell phone that will be used during the small group drawing sessions. Each small group will be have one drawer, one narrator, and one videographer. All participants will leave the conference with an individual video recording of their specific small group drawing session.


The learner will:

1. Make decisions and judgments relating to their understanding of intrinsic anatomy and relational anatomy of the hand within the context diagnostic and case specific scenarios.

2. Put concepts together in effort to recognize the value of personal and clinical collaborative work through multiple small group discussions and drawing labs centered on hand anatomy the management of hand pathology.

3. Reorganize understanding of anatomy and pathology in order to differentiate between initial and concluding knowledge of intrinsic anatomy of the hand and associated diagnoses and pathologies.

4. Create new pattern of networking with of colleagues in which to exchange ideas and contact information.

5. Make judgments regarding the difference and value of studying the intrinsics of the hand via various educational modes and media.

6. Establish clinical rationale for the anatomical and biomechanical importance of the extrinsic extensor mechanism, the flexor pulley system and the balance between the two.

7. Advance working knowledge of the etiology paradoxical extension and its role in treating flexor tendon injuries.

8. Increase understanding of the normal relationship between the flexor digitorum profundus tendon and the lumbrical muscle.

9. Establish clinical rationale and evidence of the modulating and proprioceptive role of the lumbrical muscle in relation to the flexor digitorum profundus muscle.

10. Introduce clinical framework for understanding the potential of a spectrum of paradoxical extension following Zone II flexor digitorum profundus tendon injuries

Why Attend:

The Teton Hand and Upper Extremity Conference Series, LLC has been providing professional education for occupational and physical therapists for twenty years. We specialize in the study of anatomy and treatment of upper extremity pathology utilizing an innovative learning model that couples intense education with outdoor recreation.

We recognize the changing and challenging healthcare environment and strive to provide professional education that emboldens the therapist with a foundational knowledge of anatomy, clinical reasoning, and problem-solving requisite for evidence-based practice and patient-centered clinical decisions.
