Description: An individual is immobilized in a cast for 4 to 6 weeks following a fracture. In general, what structures lose their elasticity, and what restrictions do you feel when testing range of motion, joint play, and flexibility?

Key Concepts

Connective Tissue Elasticity

Following a period of immobilization, the connective tissues—particularly the joint capsules, ligaments, and surrounding soft tissues—experience a loss of elasticity. This happens because the normal stretching and loading of these tissues are reduced, leading to a buildup of less organized collagen and a decrease in the tissues’ ability to elongate, which is essential for normal joint mobility.

Joint Contracture

Immobilization often results in joint contracture, a condition where the soft tissues around the joint become shortened and stiff. This is primarily due to the prolonged lack of movement which causes the tissues to adapt to a shortened state, leading to restrictions in a joint's range of motion, limited joint play, and decreased overall flexibility.

Range of Motion and Joint Play Assessment

When assessing a joint after immobilization, clinicians typically encounter limitations in range of motion and joint play. These restrictions reflect the underlying loss of elasticity within the connective tissues and the development of contractures, making it difficult to achieve full movement and flexibility during clinical evaluations.
