Creation of animations, illustrations and an anatomical 3D model of the hand for a web-based training of Allianz AG on the musculoskeletal system of the upper body with a focus on the anatomy of the hand. A linear, seamless animation leads through the topics of the e-learning. At defined points, the animation stops and textual information, illustrations and interactive 3D models are displayed to explain the content, or the viewer’s level of knowledge is tested by means of a quiz.

This e-Learning module provides basic knowledge of hand anatomy and common disorders.

The hand is a complex part of the human body and consists of various anatomical structures: Carpal bones, metacarpal bones, phalanges, metacarpophalangeal joints, interphalangeal and distal joints, tendons, wrist (carpal joint), hand muscles (extrinsic muscles and the intrinsic muscles). The anatomy of the hand is extremely complex and allows us to perform a variety of fine motor activities. The cooperation between bones, joints, tendons and muscles enables precise movements, grasping, touching and manipulation of objects.

The following disorders of the hand were addressed:

Carpal tunnel syndrome is a condition caused by compression of the median nerve in the wrist. The carpal tunnel is a narrow space in the wrist made up of bones and ligaments. When pressure on the nerve increases, various symptoms can occur such as numbness and tingling, lack of coordination of the fingers, and pain. Treatment of carpal tunnel syndrome can be conservative or surgical.

Rhizarthrosis is a degenerative joint disease that affects the thumb saddle joint. The thumb saddle joint is located at the base of the thumb and allows us to move the thumb against the rest of the fingers, which is important for precise hand gripping function. Rhizarthrosis is a progressive wearing away of the cartilage in the thumb saddle joint. This leads to pain, stiffness, limited mobility, and possibly the formation of bone growths (osteophytes) around the joint.

Wrist osteoarthritis is a degenerative joint disease in which the cartilage in the wrist degrades. The wrist is made up of a combination of small carpal bones and cartilage that serve as a buffer between the bones. With osteoarthritis, the cartilage wears away over time, leading to pain and limited movement.

In addition to above diseases of the hand, the following topics were covered: Atrophy of the thumb muscles, palmar fibromatosis (Dupuytren’s disease).
